Description

Technical Field

[0001] This application relates to the technical field of vehicles, and particularly relates to a pedal assembly module, a braking system, and a vehicle. Background Art

[0002] A vehicle receives an input operation from a user through a pedal assembly, thereby sensing the user's braking intention and braking the vehicle. The pedal assembly is also used to provide a rebounding force when the user steps on the foot pedal. Different users have different requirements for the magnitude of the rebounding force and the position of the foot pedal. Summary of the Utility Model

[0003] This application provides a pedal assembly module, a braking system, and a vehicle. The pedal assembly module realizes the independent installation of a pedal feel simulator and a foot pedal, so as to adapt to the needs of different users and improve the user experience.

[0004] In a first aspect, this application provides a pedal assembly module. The pedal assembly module includes a transmission member, a sensor, a foot pedal interface, and a pedal feel simulator interface. A foot pedal interface is used for drivingly connecting a foot pedal, and a pedal feel simulator interface is used for installing a pedal feel simulator. The housing of the pedal assembly module is used for accommodating a transmission member and a sensor. Among them, a transmission member is used for drivingly connecting a foot pedal through a foot pedal interface, a transmission member is used for drivingly connecting a pedal feel simulator through a push rod, and a push rod is used for squeezing one or more elastic members in a pedal feel simulator and for receiving the rebounding force of one or more elastic members.

[0005] A sensor is used for detecting the movement of a transmission member or a push rod and outputting a stroke signal or a pressure signal. A stroke signal or a pressure signal is used for indicating the braking operation output by the user to a foot pedal.

[0006] The pedal assembly module provided by this application installs a foot pedal through a foot pedal interface and installs a pedal feel simulator through a pedal feel simulator interface. Thus, a foot pedal is used for receiving the braking operation of the user and driving a transmission member through a foot pedal interface. A transmission member is used for driving a push rod to squeeze one or more elastic members in a pedal feel simulator through a pedal feel simulator interface. A transmission member is also used for receiving the rebounding force of one or more elastic members through a pedal feel simulator interface and a push rod, and transmitting the rebounding force to a foot pedal through a foot pedal interface, so as to realize the elastic feedback of the user's braking operation.

[0007] During this process, the pedal assembly module provided by this application senses the braking operation of the user through a sensor accommodated in a housing, and outputs a stroke signal or a pressure signal to achieve braking.

[0008] The pedal assembly module provided by this application separately realizes the independent installation of a pedal feel simulator and a foot pedal, facilitating the formation of different rebound forces by replacing different pedal feel simulators, and facilitating the adjustment of the position of the foot pedal or the adjustment of the material and appearance of the foot pedal by replacing different foot pedals. The pedal assembly module provided by this application facilitates the replacement of a pedal feel simulator and a foot pedal based on different user requirements to improve the user experience.

[0009] In one implementation, a foot pedal interface includes a pedal rod. One end of a pedal rod is used for driving connection with a transmission member, and the other end of a pedal rod is used for fixedly connecting with a foot pedal.

[0010] In this implementation, the pedal assembly module connects a foot pedal through a pedal rod. A pedal rod is located outside a housing, facilitating the installation of a foot pedal on a foot pedal interface.

[0011] In one implementation, a foot pedal interface includes a connecting rod accommodated inside the housing of the pedal assembly module. One end of a connecting rod is used for driving connection with a transmission member, the other end of a connecting rod is used for driving connection with one end of a pedal rod, and the other end of a pedal rod is used for fixedly connecting with a foot pedal.

[0012] In this implementation, the pedal assembly module drives and connects a pedal rod through a connecting rod. A connecting rod is accommodated inside a housing, and a housing can protect a foot pedal interface.

[0013] In one implementation, a foot pedal includes a pedal arm. A pedal arm is used for extending into a housing and fixedly connecting with a connecting rod.

[0014] In one implementation, the housing of the pedal assembly module includes two mounting surfaces. One of the pedal feel simulator interfaces includes a mounting surface. A mounting surface is used for fixedly connecting with the firewall of the vehicle and for fixedly connecting with the housing of a pedal feel simulator. A mounting surface includes a through hole, and a through hole is used for passing through a push rod. A foot pedal interface includes another mounting surface, and another mounting surface includes another through hole. Another through hole is used for passing through a pedal rod.

[0015] In this implementation, the pedal assembly module of this application is accommodated in the passenger compartment of the vehicle, and a pedal feel simulator is accommodated in the front compartment of the vehicle to reduce the space occupied by a pedal assembly in the passenger compartment. A foot pedal is installed in the passenger compartment of the vehicle through another mounting surface, facilitating the user to input a braking operation and also facilitating the installation and replacement of a foot pedal.

[0016] In one implementation, the orientations of the two mounting surfaces are perpendicular to each other. Along the orientation of one mounting surface, a through hole penetrates through one mounting surface, and along the orientation of the other mounting surface, another through hole penetrates through the other mounting surface.

[0017] In this implementation, one mounting surface is used to face the front compartment of the vehicle. A push rod axially passes through a through hole to drive-connect a transmission member and one or more elastic members of a pedal feel simulator. The other mounting surface is used to face the lower part of the passenger compartment, and the transmission connection between a foot pedal and a transmission member is avoided through the other through hole.

[0018] In one implementation, the pedal assembly module includes a push rod. A push rod is used to extend out of a housing from a through hole and drive-connect one or more elastic members in a pedal feel simulator.

[0019] In one implementation, a pedal feel simulator includes a push rod. A push rod is used to extend into a housing through a through hole and drive-connect with a transmission member.

[0020] In one implementation, a through hole axially includes two sections. One section is closer to a mounting surface compared to the other section, and the inner diameter of one section is larger than that of the other section.

[0021] In this implementation, a pedal feel simulator interface is fixedly connected to the housing of a pedal feel simulator through the section with a larger inner diameter in a through hole. The pedal feel simulator interface reduces the gap between the two through the cooperation between the inner peripheral surface of the section with a smaller inner diameter in a through hole and the outer peripheral surface of a push rod to protect the interior of the housing.

[0022] In one implementation, the inner diameter of the other section is equal to the outer diameter of a push rod.

[0023] In this implementation, the other section of a through hole is used to cooperate with a push rod to seal the interior of the housing. The other section of a through hole is also used to limit the radial displacement of a push rod to ensure reliable transmission between a push rod and a transmission member.

[0024] In one implementation, the inner peripheral surface of a through hole includes a plurality of mounting shoulders. Each mounting shoulder includes an axial section and a circumferential section. Along the axis of a through hole, one end of an axial section is located on a mounting surface, and the other end of the axial section is used to communicate with a circumferential section. Along the circumference of a through hole, the axial sections are arranged at intervals, and each circumferential section is located on the same side of the axial section it communicates with.

[0025] In this implementation, multiple mounting spigots are used to fix the housing of a pedal feel simulator. Each axial section is used to allow the housing of a pedal feel simulator to extend into a through hole, and each circumferential section is used to allow the housing of a pedal feel simulator to rotate and be fixed within a through hole. The housing of a pedal feel simulator is fixed within the housing of a pedal assembly module by extending and then rotating, which facilitates installation and replacement.

[0026] In one implementation, along the axis of a through hole, the distances from multiple circumferential sections to a mounting surface are equal.

[0027] In this implementation, along the axis of a through hole, the axial widths of multiple axial sections are equal, which facilitates the installation of the housing of a pedal feel simulator within multiple mounting spigots and also facilitates the machining of the multiple mounting spigots and the housing of a pedal feel simulator.

[0028] In one implementation, along the axis of a through hole, the axial widths of each circumferential section are equal.

[0029] In this implementation, the axial widths of each circumferential section are equal, which facilitates controlling the angle at which the housing of a pedal feel simulator is screwed into a through hole and also facilitates the machining of multiple mounting spigots.

[0030] In one implementation, along the circumference of a through hole, the arc lengths of multiple circumferential sections are less than the spacing between adjacent two axial sections.

[0031] In this implementation, along the circumference of a through hole, the circumferential spacing between adjacent two axial sections is greater than the arc length of a circumferential section located between the adjacent two axial sections, so that when mounting a pedal feel simulator on a mounting surface, the end of each circumferential section away from the axial section it is connected to can define the rotation angle of a pedal feel simulator.

[0032] In one implementation, along the circumference of a through hole, the arc lengths of each circumferential section are equal, so that when mounting a pedal feel simulator on a mounting surface, the end of each circumferential section away from the axial section it is connected to can cooperate to define the rotation angle during the installation of a pedal feel simulator and also facilitates the machining of each mounting spigot.

[0033] In one implementation, along the axis of a push rod, the difference in length dimensions between another through hole and a pedal rod is less than the maximum compression amount of one or more elastic members in a pedal feel simulator.

[0034] In this implementation manner, the pedal assembly module includes a pedal rod. One end of the pedal rod is received in a housing and is in driving connection with a transmission member or a connecting rod. The other end of the pedal rod extends out from another through hole and is fixedly connected to a foot pedal. When the user inputs a braking operation through a foot pedal, the pedal rod moves relative to the housing towards the mounting surface along with the user's braking operation. Along the axial direction of a push rod, the length dimension of the other through hole is used to define the moving stroke of the pedal rod.

[0035] Along the axial direction of a push rod, the difference between the length dimension of the other through hole and that of the pedal rod is the moving stroke of the pedal rod within the other through hole. The moving stroke of the pedal rod within the other through hole is less than the maximum compression amount of one or more elastic members in a pedal feel simulator to prevent damage to one or more elastic members due to an excessive stroke of the pedal rod.

[0036] In one implementation manner, a foot pedal includes a pedal arm. Along the axial direction of a push rod, the difference between the length dimension of the other through hole and that of the pedal arm is less than the maximum compression amount of one or more elastic members in a pedal feel simulator.

[0037] In this implementation manner, a foot pedal includes a pedal arm. The pedal arm is used to extend into a housing and is connected to a transmission member or a connecting rod. When the user inputs a braking operation through a foot pedal, the pedal arm moves relative to the housing towards the mounting surface along with the user's braking operation. Along the axial direction of a push rod, the length dimension of the other through hole is used to define the moving stroke of the pedal arm.

[0038] Along the axial direction of a push rod, the difference between the length dimension of the other through hole and that of the pedal arm is the moving stroke of the pedal arm within the other through hole. The moving stroke of the pedal arm within the other through hole is less than the maximum compression amount of one or more elastic members in a pedal feel simulator to prevent damage to one or more elastic members due to an excessive stroke of the pedal arm.

[0039] In one implementation manner, along the axial direction of a push rod, the difference between the length dimension of the other through hole and that of the transmission member is less than the maximum compression amount of one or more elastic members in a pedal feel simulator.

[0040] In this implementation manner, the pedal rod is outside the housing. A transmission member is used to extend out from the other through hole and is in driving connection with the pedal rod. When the user inputs a braking operation through a foot pedal, the pedal rod moves relative to the housing towards the mounting surface along with the user's braking operation and drives the transmission member to also move towards the mounting surface. Along the axial direction of a push rod, the length dimension of the other through hole is used to define the moving stroke of the transmission member.

[0041] Along the axis of a push rod, the difference between the length dimension of another through hole and that of a transmission member is the moving stroke of the transmission member within the other through hole. The moving stroke of a transmission member within the other through hole is less than the maximum compression amount of one or more elastic members in a pedal feel simulator to prevent damage to one or more elastic members caused by an excessive stroke of the transmission member.

[0042] In one implementation, one end of a pedal rod includes a slide rail. The pedal rod is used to drive-connect a transmission member through a slide rail. When a push rod does not press on a pedal feel simulator, the extending direction of the slide rail is parallel to the axis of the push rod.

[0043] In this implementation, a transmission member includes a chute for mating with the slide rail to achieve the installation of the pedal rod and the transmission member. Alternatively, a connecting rod includes a chute for mating with the slide rail to achieve the installation of the pedal rod and the connecting rod.

[0044] In one implementation, along the radial direction of a push rod, the slide rail includes a protrusion extending towards the transmission member. When the push rod does not press on the pedal feel simulator, along the axial direction of the push rod, the protrusion includes an abutting surface facing an installation surface. The distance between the abutting surface and the installation surface is less than the distance between the slide rail and the installation surface. The abutting surface includes a bolt hole. One end of the pedal rod is used to fixedly connect to the transmission member through the bolt hole.

[0045] In this implementation, a transmission member includes a chute, or a connecting rod includes a chute. A protrusion of the slide rail is used to embed into the bottom of the chute and abut against the transmission member or the connecting rod along the axial direction of the push rod to limit the sliding displacement of the pedal rod and reliably transmit the braking driving force applied by the user to the foot pedal via the pedal rod.

[0046] On the other hand, along the axial direction of the push rod, the transmission member or the connecting rod includes another abutting surface abutting against the slide rail, and the other abutting surface faces away from the installation surface. The other abutting surface includes a communication hole. When an abutting surface of the protrusion abuts against the other abutting surface, the bolt hole communicates with the communication hole, and a bolt realizes the fixed connection between the pedal rod and the transmission member or the connecting rod through the bolt hole and the communication hole.

[0047] In one implementation, a transmission member includes a rotating arm. One end of the rotating arm is used to rotatably connect to the housing of the pedal assembly module, the other end of the rotating arm is used to drive-connect a foot pedal, and the middle section of the rotating arm is used to abut against a push rod along the axial direction of the push rod.

[0048] In this implementation, the other end of a rotating arm is used for fixedly connecting to a pedal rod. When a user inputs a braking operation through a foot pedal, both the pedal rod and the other end of the rotating arm rotate around one end of the rotating arm following the user's braking operation. The middle section of the rotating arm rotates towards a mounting surface following the rotation of the other end of the rotating arm, and pushes a push rod to squeeze one or more elastic members of a pedal feel simulator. Thus, the braking driving force exerted by the user on a foot pedal is transmitted into a pedal feel simulator.

[0049] In one implementation, a rotating arm and a connecting rod are of an integral structure. That is to say, the other end of the rotating arm is used for drivingly connecting a foot pedal through a pedal rod. Alternatively, one end of the connecting rod is used for rotatably connecting to the housing of the pedal assembly module.

[0050] In one implementation, the other end of the rotating arm is used for extending out of a housing and fixedly connecting to a pedal rod or to a foot pedal.

[0051] In one implementation, the pedal assembly module includes a sensor interface, and the sensor interface is used for mounting a transmission terminal. A sensor is used for outputting a travel signal or a pressure signal through a transmission terminal.

[0052] In this implementation, a transmission terminal is used for electrically connecting to a sensor, and the transmission terminal is also used for communicatively connecting to an external circuit. When a user inputs a braking operation through a foot pedal, a rotating arm or a push rod exerts the braking driving force applied by the user on the foot pedal on the sensor. The sensor is used for detecting the braking driving force transmitted by the rotating arm or the push rod and outputting a pressure signal, and the pressure signal is output through a transmission terminal to reflect the braking intention of the user. Alternatively, when a user inputs a braking operation through a foot pedal, a rotating arm or a push rod generates an axial displacement based on the braking driving force applied by the user on the foot pedal. The sensor is used for detecting the axial displacement of the rotating arm or the push rod and outputting a travel signal, and the travel signal is output through a transmission terminal to reflect the braking intention of the user.

[0053] In one implementation, a sensor interface includes a third mounting surface, and the third mounting surface includes a third through hole. The third through hole is used for passing through a transmission terminal to facilitate the electrical connection between the transmission terminal and the sensor.

[0054] In one implementation, the orientation of the third mounting surface is perpendicular to the orientation of one mounting surface and opposite to the orientation of the other mounting surface, and a third through hole penetrates the third mounting surface along the direction of the third mounting surface so that a transmission terminal connected to communicate with an external circuit passes through a shell and is electrically connected to a sensor.

[0055] In one implementation, the pedal assembly module further includes a controller, which is used to output a control signal according to a travel signal or a pressure signal, and the control signal is used to instruct one or more braking devices of the vehicle to brake the wheels of the vehicle.

[0056] In this implementation, a controller is used to communicate with a sensor, and a controller is also used to communicate with the circuits in one or more brake devices of the vehicle. When a user inputs a braking operation through a foot pedal, a sensor outputs a pressure signal or a travel signal by detecting a rotating arm or a push rod, and a pressure signal or a travel signal is output to a controller. A controller is used to process a pressure signal or a travel signal and output a control signal to the circuits of one or more brake devices of the vehicle. The one or more brake devices of the vehicle brake the wheels of the vehicle based on a control signal, thereby reflecting the user's braking intention.

[0057] In one implementation, a controller is communicatively connected to one or more braking devices of a vehicle via a transmission terminal. A transmission terminal is used to output a control signal of a controller.

[0058] In a second aspect, the present application provides a pedal assembly, which includes a foot pedal, a pedal feel simulator, and the pedal assembly module provided in the first aspect, a foot pedal interface of the pedal assembly module is used for transmission connection to a foot pedal, and a pedal feel simulator interface of the pedal assembly module is used for installing a pedal feel simulator.

[0059] The pedal assembly provided in the present application facilitates replacement of a pedal feel simulator and a foot pedal based on different user needs to enhance the user experience.

[0060] In one implementation, a pedal feel simulator includes another sensor, which is used to electrically connect to a transmission terminal through a pedal feel simulator interface, and another sensor is used to detect the movement of a push rod or one or more elastic members and to output another travel signal or another pressure signal through a transmission terminal.

[0061] In this implementation, another stroke signal or another pressure signal output by another sensor is used to cooperate with a stroke signal or a pressure signal output by one sensor to form control redundancy. When one of one sensor or another sensor fails, it is ensured that the stroke signal or pressure signal output by the other of one sensor or another sensor can be output through a transmission terminal.

[0062] In one implementation, another sensor is used to electrically connect to a controller through a pedal feel simulator interface. The controller is used to receive another stroke signal or another pressure signal output by another sensor. The controller can selectively respond to one of a stroke signal or a pressure signal output by one sensor and another stroke signal or another pressure signal output by another sensor to output a control signal. When one of one sensor or another sensor fails, the controller can output a control signal based on the stroke signal or pressure signal output by the other of one sensor or another sensor and transmit it to one or more braking devices of the vehicle. Thus, the braking intention of the user is reflected.

[0063] In one implementation, one or more elastic members include at least one of a spring, a hydraulic piston, and a pneumatic piston.

[0064] In a third aspect, the present application provides a braking system. The braking system includes at least one electromechanical braking device and a pedal assembly module provided in the first aspect. Each electromechanical braking device is used to brake a wheel in response to a braking operation of a user on a foot pedal indicated by a pedal assembly module. Alternatively, the present application provides a braking system. The braking system includes at least one electromechanical braking device and a pedal assembly provided in the second aspect. Each electromechanical braking device is used to brake a wheel in response to a braking operation of a user on a foot pedal of a pedal assembly.

[0065] In a fourth aspect, the present application provides a vehicle. The vehicle includes a plurality of wheels and a braking system provided in the third aspect. Each electromechanical braking device in the braking system is used to brake a wheel.

[0066] Both the electromechanical braking device provided in the third aspect of the present application and the vehicle provided in the fourth aspect are convenient to replace a pedal feel simulator and a foot pedal based on different user requirements to improve the user experience because they adopt the pedal assembly module provided in the first aspect of the present application.

[0112] Please refer to Figure 2 and Figure 3 where Figure 2 is a schematic flow chart of the braking system 1002 of the vehicle provided by the embodiment of this application, Figure 3 is a schematic structural diagram at the wheel of the vehicle provided by the embodiment of this application.

[0113] As Figure 2 and Figure 3 shown, the electromechanical braking device 1004 includes a braking motor 1005 and a brake 1006. The brake 1006 is used to fixedly connect to the vehicle body 1001. The braking motor 1005 is used to respond to the braking operation of the foot pedal 201 of the user acting on the pedal assembly 200, and based on the braking operation of the user, output braking force to the brake 1006. The brake 1006 can brake the brake disc 1003 under the action of the braking force output by the braking motor 1005.

[0114] In one embodiment, the brake 1006 includes a brake caliper, a caliper bracket and friction pads. Among them, the caliper bracket is used to fixedly connect to the vehicle body 1001. The brake caliper is slidably connected to the caliper bracket. The brake caliper is used to fixedly connect to the braking motor 1005, and the braking motor 1005 can slide synchronously with the brake caliper relative to the caliper bracket.

[0115] The brake caliper is also used to install friction pads. In one embodiment, the number of friction pads is two, and the two friction pads are arranged on both sides of the brake disc 1003 along the axial direction of the brake disc 1003. The two friction pads respectively face the two outer surfaces of the brake disc 1003 that are opposite to each other.

[0116] The braking motor 1005 is used to drive two friction plates to slide axially towards each other along the brake disc 1003 until the two friction plates contact the two outer surfaces of the brake disc 1003 facing away from each other, so as to generate frictional force to brake the brake disc 1003. The braking motor 1005 is also used to drive the two friction plates to slide axially away from the brake disc 1003 along the axial direction of the brake disc 1003 and separate from the two outer surfaces of the brake disc 1003 facing away from each other to release the braking of the brake disc 1003. That is, in this embodiment, the braking motor 1005 is used to drive the two friction plates towards or away from the brake disc 1003.

[0117] As Figure 2 and Figure 3 shown, the pedal assembly 200 provided in the present application is used for communication connection with the braking motors 1005 of each electro-mechanical braking device 1004. The pedal assembly 200 is used to output a control signal to indicate the braking operation of the user, and the braking motor 1005 is used to rotate forward in response to the control signal output by the pedal assembly 200. In one embodiment, the pedal assembly 200 is used to output a stroke signal to indicate the braking operation of the user, and the braking motor 1005 is used to rotate forward in response to the stroke signal output by the pedal assembly 200. In one embodiment, the pedal assembly is used to output a pressure signal to indicate the braking operation of the user, and the braking motor 1005 is used to rotate forward corresponding to the pressure signal output by the pedal assembly 200.

[0118] The braking motor 1005 rotates forward to output braking force to the brake 1006, and makes the friction plate close to the braking motor 1005 along the axial direction of the brake disc 1003 slide towards the brake disc 1003 until the friction plate abuts against the brake disc 1003. At this time, the braking motor 1005 continues to rotate forward to output braking force, and this part of the braking force is transmitted to the brake caliper through the friction plate and the internal structure of the brake 1006, and makes the brake caliper slide relative to the caliper bracket, so as to drive the friction plate away from the braking motor 1005 along the axial direction of the brake disc 1003 to slide towards the brake disc 1003 until the friction plate abuts against the brake disc 1003. Thus, the two friction plates are brought into contact with the two outer surfaces of the brake disc 1003 facing away from each other, and the braking of the wheel is achieved.

[0119] The pedal assembly 200 is also used to indicate the user to end the braking operation by interrupting the control signal, and the braking motor 1005 responds to the interruption of the control signal and rotates in reverse to cooperate with the internal structure of the brake 1006 to drive the two friction plates to slide axially away from the brake disc 1003 along the axial direction of the brake disc 1003 until the two friction plates are separated from the two outer surfaces of the brake disc 1003 facing away from each other respectively. Thus, the braking of the wheel is released, and the wheel can continue to rotate to drive the vehicle to travel.

[0120] Please refer to Figures 4 - 8 , in which Figure 4Schematic diagram of the installation structure of the pedal assembly 200 in the vehicle provided by the embodiment of the present application Figure 5 Schematic diagram of the external structure of the pedal assembly 200 provided by the embodiment of the present application Figure 6 Schematic sectional view of the pedal assembly 200 provided by the embodiment of the present application Figure 7 Exploded view of the pedal assembly 200 provided by the embodiment of the present application Figure 8 Partial sectional view of the pedal assembly module 100 provided by the embodiment of the present application

[0121] As Figures 4 - 8 As shown, the pedal assembly 200 provided by the present application includes a foot pedal 201, a pedal feel simulator 202, and a pedal assembly module 100. Among them, the foot pedal 201 and the pedal feel simulator 202 are respectively installed on the pedal assembly module 100. The foot pedal 201 is used to receive the braking operation of the user, and the pedal feel simulator 202 is used to provide elastic feedback to the foot pedal 201 after receiving the braking driving force applied by the user. In one embodiment, the housing of the pedal assembly module 100 is installed on the firewall 1007 of the vehicle. The foot pedal 201 is located in the passenger compartment of the vehicle body 1001 to facilitate responding to the braking operation of the user. In one embodiment, the pedal feel simulator 202 is accommodated in the front compartment of the vehicle body 1001 to reduce the space occupied by the pedal assembly 200 in the passenger compartment.

[0122] The pedal assembly module 100 includes a housing, a transmission member 20, a sensor, a foot pedal interface 30, and a pedal feel simulator interface 40. For ease of description, the housing of the pedal assembly module 100 is defined as the first housing 10, and the housing of the pedal feel simulator 202 is defined as the second housing 2021.

[0123] Among them, the first housing 10 of the pedal assembly module 100 is used to accommodate the transmission member 20 and the sensor. The foot pedal interface 30 is used for driving connection with the foot pedal 201, and the pedal feel simulator interface 40 is used for installing the pedal feel simulator 202. During the assembly process of the pedal assembly 200 of the present application, the foot pedal 201 is drivingly connected to the transmission member 20 through the foot pedal interface 30, and the pedal feel simulator 202 is drivingly connected to the transmission member 20 through the pedal feel simulator interface 40. That is, the foot pedal 201 is installed on the pedal assembly module 100 of the present application through the foot pedal interface 30, and the pedal feel simulator 202 is installed on the pedal assembly module 100 of the present application through the pedal feel simulator interface 40, thereby assembling into a pedal assembly 200.

[0124] During the process of the user inputting a braking operation, the user applies a braking driving force to the foot pedal 201 by stepping on the foot pedal 201. This braking driving force can be transmitted into the transmission member 20 through the foot pedal interface 30, and the transmission member 20 transmits the braking driving force into the pedal feel simulator 202 through the pedal feel simulator interface 40. After receiving the braking driving force, the pedal feel simulator 202 transmits a reverse rebounding force to the transmission member 20, and this rebounding force is transmitted to the foot pedal 201 through the transmission member 20, thereby realizing the elastic feedback of the user's braking operation.

[0125] The present application does not limit the specific implementation manner of the transmission member 20. In one embodiment, the transmission member 20 of the pedal assembly module 100 of the present application is a single part. In another embodiment, the transmission member 20 is an assembly. In another embodiment, the transmission member 20 is a partial structure of a single part.

[0126] In one embodiment, the pedal assembly module 100 further includes a push rod 50, and the push rod 50 is drivingly connected between the transmission member 20 and the pedal feel simulator 202. That is to say, the transmission member 20 is drivingly connected to the pedal feel simulator 202 through the pedal feel simulator interface 40 and the push rod 50. In another embodiment, the pedal feel simulator 202 includes a push rod, and the pedal feel simulator 202 is drivingly connected to the transmission member 20 through the push rod.

[0127] In the embodiment of the present application, the transmission member 20 transmits the braking driving force transmitted to the transmission member 20 into the pedal feel simulator 202 through the pedal feel simulator interface 40 and the push rod 50. The pedal feel simulator 202 is used to absorb the braking driving force transmitted by the push rod 50, and based on the absorbed braking driving force, apply a rebounding force to the transmission member 20 through the push rod 50 and the pedal feel simulator interface 40. That is to say, the pedal feel simulator 202 is used to apply a rebounding force to the user when the user inputs a braking operation, so as to realize the elastic feedback of the user's braking operation. In one embodiment, the pedal feel simulator 202 includes an elastic member.

[0128] When the user inputs a braking operation, the user applies a braking driving force to the pedal assembly 200 by stepping on the foot pedal 201. The foot pedal 201 displaces relative to the pedal assembly module 100 under the action of the braking driving force, and drives the transmission member 20 to displace relative to the pedal assembly 200 through the foot pedal interface 30. The transmission member 20 drives the push rod 50 to displace towards the elastic member through the pedal feel simulator interface 40 and squeezes the elastic member. The elastic member generates an elastic deformation under the extrusion of the push rod 50, and applies a reverse rebounding force to the push rod 50 based on its own elastic deformation. The push rod 50 is used to absorb the rebounding force of the elastic member, and acts on the transmission member 20 through the pedal feel simulator interface 40. The transmission member 20 transmits the rebounding force to the foot pedal 201 through the foot pedal interface 30, and the foot pedal 201 applies it to the user.

[0129] That is, during the process of the user inputting a braking operation, the foot pedal 201 is used to receive the braking operation of the user, and the pedal assembly module 100 is used to transmit the braking driving force applied by the user to the foot pedal 201 to the pedal feel simulator 202. The pedal feel simulator 202 receives the braking driving force through the deformation of the elastic member, and releases the rebound force based on the deformation of the elastic member. The rebound force of the elastic member acts on the user through the pedal assembly module 100 and the foot pedal 201 in sequence, and enables the user to receive an elastic force in the direction opposite to the braking driving force applied by the user. Thus, the elastic force feedback for the user's braking operation is realized.

[0130] Since when the user steps on the foot pedal 201, the foot pedal 201 will gradually displace along with the stepping of the user. And the larger the displacement amount of the foot pedal 201 is, the greater the torque output by the pedal assembly 200 indicating the braking motor 1005 is. Correspondingly, the braking force of the brake 1006 on the brake disc 1003 is greater, and the vehicle can be braked faster under the action of the electromechanical braking device 1004. That is, the displacement amount of the foot pedal 201 is related to the actual braking speed of the vehicle.

[0131] The elastic member of the pedal feel simulator 202 is used to apply a rebound force in the direction opposite to the braking driving force to the user when the user steps on the foot pedal 201, so that the user can indirectly judge the magnitude of the braking force of the brake 1006 on the brake disc 1003 through the magnitude of the rebound force, which is convenient for the user to control the displacement amount of the foot pedal 201 by adjusting the braking driving force applied to the foot pedal 201 to match the user's braking intention.

[0132] After the user cancels the braking operation, the rebound force stored in the elastic member of the pedal feel simulator 202 is used to drive the push rod 50 to slide towards the transmission member 20, and push the transmission member 20 to displace in the reverse direction. The transmission member 20 drives the foot pedal 201 to displace in the reverse direction based on the rebound force of the elastic member until the foot pedal 201 moves to the initial position. So as to facilitate the user to input a braking operation through the foot pedal 201 again.

[0133] For the pedal assembly 200 including the pedal assembly module 100 of the present application, considering that there are differences in the requirements of different users for the pedal assembly 200. For example, in order to meet the requirements of different users for elastic force feedback, it is usually necessary to adjust the magnitude of the rebound force of the elastic member in the pedal feel simulator 202. In order to meet the requirements of different users for the foot pedal, it is usually necessary to adjust the position, appearance, or material of the foot pedal 201 to facilitate the user to step on or improve the appearance effect. In the prior art, the pedal feel simulator, the foot pedal, and the pedal assembly module are usually integrated in a pedal assembly, and it is difficult to adjust or replace the pedal feel simulator 202 or the foot pedal 201, which is not conducive to meeting the personalized needs of different users. On the other hand, it is also not conducive to the maintenance and repair of the pedal feel simulator 202 or the foot pedal 201.

[0134] In the pedal assembly module 100 of the present application, the pedal 201 and the pedal feel simulator 202 are independently installed through the pedal interface 30 and the pedal feel simulator interface 40 respectively. When different users have different requirements for the pedal 201 and / or the pedal feel simulator 202, the pedal assembly module 100 of the present application facilitates forming different rebound forces by replacing different pedal feel simulators 202, and / or facilitates adjusting the position of the pedal 201 or adjusting the material and appearance of the pedal 201 by replacing different pedals 201. Thereby, different user requirements are met, and subsequent maintenance and servicing are facilitated.

[0135] On the other hand, when matching different user requirements, only the customized pedal feel simulator 202 and / or the pedal 201 need to be matched, and the pedal assembly module 100 of the pedal assembly 200 does not need to be replaced, reducing the manufacturing cost of the vehicle.

[0136] In the embodiment of the present application, the pedal interface 30 refers to a part, a component, or a part of a part in the pedal assembly module 100 of the present application for installing the pedal 201. When installing the pedal 201, the pedal 201 is installed through the remaining structure of the pedal assembly 200 within the pedal interface 30. Correspondingly, the pedal feel simulator interface 40 refers to a part, a component, or a part of a part in the pedal assembly module 100 of the present application for installing the pedal feel simulator 202. When installing the pedal feel simulator 202, the pedal feel simulator 202 is installed through the remaining structure of the pedal assembly 200 within the pedal feel simulator interface 40.

[0137] In the embodiment of the present application, the pedal assembly module 100 includes a sensor for detecting the movement of the transmission member 20 or the push rod 50 and outputting a stroke signal or a pressure signal.

[0138] For ease of description, the sensor of the pedal assembly module 100 is defined as the first sensor 60. Correspondingly, the first sensor 60 can be a displacement sensor and is used to output a stroke signal. When the stroke signal output by the first sensor 60 is defined as the first stroke signal; when the first sensor 60 can be a pressure sensor and is used to output a pressure signal, the pressure signal output by the first sensor 60 is defined as the first pressure signal.

[0139] In the embodiment of the present application, the first sensor 60 is used to detect the movement of the transmission member 20 or the push rod 50 and output the first stroke signal or the first pressure signal. That is, the pedal assembly module 100 senses the user's braking operation through the first sensor 60 and outputs the first stroke signal or the first pressure signal to achieve braking.

[0140] During the process of the user inputting a braking operation, the braking driving force applied to the foot pedal 201 is transmitted to the transmission member 20 and the push rod 50 via the foot pedal interface 30, and causes the transmission member 20 and the push rod 50 to displace relative to the first housing 10. The first sensor 60 is used to detect the displacement amount of the transmission member 20 or the push rod 50 along the axial direction of the push rod 50, and outputs a first stroke signal.

[0141] In another embodiment, the transmission member 20 includes a groove, and the push rod 50 includes a piston. The piston is used to be embedded in the groove. Along the sliding direction of the piston relative to the first housing 10, the length of the piston is less than the length of the groove. The piston is used to enclose a sealed piston chamber with the groove, and the piston chamber is used to accommodate the first sensor 60. During the process of the user inputting a braking operation, the piston is used to squeeze the piston chamber along with the movement of the foot pedal 201 to change the internal pressure of the piston chamber. The first sensor 60 outputs a first pressure signal by detecting the pressure in the piston chamber.

[0142] In the embodiment of the present application, both the first stroke signal or the first pressure signal output by the first sensor 60 can reflect the magnitude of the braking driving force transmitted by the transmission member 20 or the push rod 50. During the process of the user inputting a braking operation, the pedal assembly module 100 of the present application controls the braking motor 1005 of each electro-mechanical braking device 1004 to operate according to the first stroke signal or the first pressure signal output by the first sensor 60. That is, the first stroke signal or the first pressure signal is used to indicate the braking operation output by the user to the foot pedal 201, so that the braking effect of each electro-mechanical braking device 1004 on the wheels matches the user's braking intention. Thus, the pedal assembly module 100 of the present application reflects the user's braking intention according to the first stroke signal or the first pressure signal output by the first sensor 60.

[0143] In one embodiment, the pedal assembly module 100 further includes a controller 70. The controller 70 is used to output a control signal according to the first stroke signal or the first pressure signal. The control signal is used to indicate one or more electro-mechanical braking devices 1004 of the vehicle to brake the wheels of the vehicle. That is, when the user inputs a braking operation to the foot pedal 201, the first stroke signal or the first pressure signal output by the first sensor 60 will be processed by the controller 70 first and then converted into a control signal and transmitted to the braking motor 1005, and then the brake disc 1003 is abutted through the same power transmission path as above, thereby braking the vehicle.

[0144] In one embodiment, the pedal feel simulator 202 includes another sensor, which is used to detect the movement of the push rod 50 or the elastic member and to output another travel signal or another pressure signal. For ease of description, the sensor of the pedal feel simulator 202 is defined as a second sensor. Correspondingly, when the second sensor outputs a travel signal, the travel signal output by the second sensor is defined as a second travel signal. Or when the second sensor outputs a pressure signal, the pressure signal output by the second sensor is defined as a second pressure signal.

[0145] In the embodiment of the present application, the pedal feel simulator 202 includes a second sensor, which is used to detect the movement of the push rod 50 or the elastic member and to output a second travel signal or a second pressure signal. That is, the pedal feel simulator 202 senses the user's braking operation and outputs a second travel signal or a second pressure signal to achieve braking.

[0146] During the process of the user inputting the braking operation, the braking driving force applied to the pedal 201 is transmitted to the transmission member 20 via the pedal interface 30, and the transmission member 20 drives the push rod 50 to move and squeeze the elastic member through the pedal feel simulator 202. The push rod 50 or the end of the elastic member abutting against the push rod 50 is displaced relative to the second housing 2021. The second sensor is used to detect the displacement of the end of the push rod 50 or the elastic member abutting against the push rod 50, and output a second stroke signal.

[0147] In another embodiment, the pedal feel simulator 202 further includes a piston, and the second housing 2021 includes a groove. The piston is accommodated in the second housing 2021 and is used to be embedded in the groove. Along the sliding direction of the piston relative to the second housing 2021, one end of the piston is connected to the elastic member or the push rod 50 in a transmission manner, and the length of the other end of the piston is less than the length of the groove. The other end of the piston is used to enclose the groove to form a sealed piston cavity, and the piston cavity is used to accommodate the second sensor. During the user input braking operation, the piston is used to squeeze the piston cavity with the movement of the foot pedal 201 to change the internal pressure of the piston cavity. The second sensor outputs a second pressure signal by detecting the pressure in the piston cavity.

[0148] In the embodiment of the present application, both the second stroke signal or the second pressure signal output by the second sensor can reflect the magnitude of the braking driving force transmitted by the push rod 50 or the elastic member. During the process of the user inputting a braking operation, the pedal assembly 200 of the present application can also control the operation of the braking motor 1005 of each electromechanical braking device 1004 according to the second stroke signal or the second pressure signal output by the second sensor. That is, the second stroke signal or the second pressure signal is used to indicate the braking operation output by the user to the foot pedal 201, so that the braking effect of each electromechanical braking device 1004 on the wheel matches the user's braking intention. Thus, the pedal assembly 200 of the present application reflects the user's braking intention according to the second stroke signal or the second pressure signal output by the second sensor.

[0149] On the other hand, the second stroke signal or the second pressure signal output by the second sensor is also used to cooperate with the first stroke signal or the first pressure signal output by the first sensor 60 to achieve control redundancy. In the embodiment of the present application, the pedal assembly 200 of the present application can control the operation of the braking motor 1005 based on the first stroke signal or the first pressure signal output by the first sensor 60, or can also control the operation of the braking motor 1005 based on the second stroke signal or the second pressure signal output by the second sensor. When one of the first sensor 60 and the second sensor fails, the pedal assembly 200 of the present application can realize the operation control of the braking motor 1005 through the other one of the first sensor 60 and the second sensor, ensuring the reliable response of the pedal assembly 200 of the present application to the user's braking operation and improving the safety and reliability of the pedal assembly 200 of the present application.

[0150] In one embodiment, the second sensor is used to be electrically connected to the controller 70 through the pedal feel simulator interface 40. The controller 70 is further used to receive the second stroke signal or the second pressure signal output by the second sensor and output a control signal according to the second stroke signal or the second pressure signal. That is, when the user inputs a braking operation to the foot pedal 201, the controller 70 can selectively respond to one of the first stroke signal or the first pressure signal output by the first sensor 60 and the second stroke signal or the second pressure signal output by the second sensor to output a control signal.

[0151] In an embodiment of the present application, when the first sensor 60 fails and cannot output a correct first stroke signal or first pressure signal, the second stroke signal or second pressure signal transmitted to the controller 70 will be converted into a control signal by the controller 70 and then transmitted to the brake motor 1005, and then the brake disc 1003 will be abutted through the same power transmission path as above, thereby braking the vehicle. When the second sensor fails and cannot output a correct second stroke signal or second pressure signal, the first stroke signal or first pressure signal transmitted to the controller 70 will be converted into a control signal by the controller 70 and then transmitted to the brake motor 1005, and then the brake disc 1003 will be abutted through the same power transmission path as above, thereby braking the vehicle. Thus, the braking intention of the user is reflected.

[0152] In one embodiment, the vehicle includes a vehicle control unit (VCU). The control signal output by the controller 70 in the pedal assembly module 100 can be transmitted to the vehicle control unit for processing, and then the vehicle control unit controls the electromechanical braking device 1004 to achieve braking.

[0153] In one embodiment, the first stroke signal or first pressure signal output by the first sensor 60 of the pedal assembly module 100 can be directly transmitted to the vehicle control unit, and after being processed by the vehicle control unit, the vehicle control unit controls the electromechanical braking device 1004 to achieve braking.

[0154] After the vehicle of the present application introduces the vehicle control unit to process the first stroke signal or first pressure signal of the pedal assembly module 100, the vehicle control unit can further form a safety redundancy effect on the control signal output by the controller 70, thereby further improving the safety and reliability of the vehicle.

[0155] In one embodiment, the number of elastic members of the pedal feel simulator 202 is one. In another embodiment, the number of elastic members of the pedal feel simulator 202 is multiple.

[0156] In one embodiment, one or more elastic members include at least one of a spring, a hydraulic piston, and a pneumatic piston.

[0157] In one embodiment, a pedal interface 30 includes a pedal rod 31. One end of a pedal rod 31 is used for driving connection with a transmission member 20, and the other end of a pedal rod 31 is used for fixedly connecting a foot pedal 201. For ease of description, the end of the pedal rod 31 drivingly connected to the transmission member 20 is defined as the first end 31a, and the end of the pedal rod 31 fixedly connected to the foot pedal 201 is defined as the second end 31b.

[0158] Please refer to Figure 9, where Figure 9 is a schematic diagram of the connection structure of the foot pedal 201 in an embodiment of the pedal assembly 200 provided by the present application.

[0159] As Figure 9 shown, the pedal rod 31 is located outside the first housing 10. The first end 31a of the pedal rod 31 is used for driving connection with the transmission member 20, and the second end 31b of the pedal rod 31 is used for fixedly connecting with the foot pedal 201. Along the self-extending axis direction of the pedal rod 31, the first end 31a of the pedal rod 31 is closer to the first housing 10 than the second end 31b of the pedal rod 31.

[0160] During the user's input of the braking operation, the braking driving force applied by the user to the foot pedal 201 causes the pedal rod 31 to displace relative to the first housing 10, and drives the transmission member 20 to displace relative to the first housing 10. The transmission member 20 squeezes the elastic member in the pedal feel simulator 202 through the push rod 50 and receives the rebounding force provided by the elastic member. The rebounding force is sequentially transmitted to the foot pedal 201 through the push rod 50, the transmission member 20, and the pedal rod 31, and acts on the user to achieve the elastic feedback of the user's braking operation.

[0161] In the embodiment of the present application, a part of the structure of the transmission member 20 is located outside the first housing 10 and is in driving connection with the first end 31a of the pedal rod 31. Since the second end 31b of the pedal rod 31 is fixedly connected to the foot pedal 20. When the foot pedal 201 is installed on the pedal assembly module 100 of the present application, the foot pedal 201 is installed on the pedal assembly module 100 of the present application through the driving connection between the pedal rod 31 and the connecting rod 32. That is, the foot pedal interface 30 of the pedal assembly module 100 of the present application is a structure for realizing the fixed connection between the pedal rod 31 and the transmission member 20.

[0162] Since the structure for realizing the fixed connection between the pedal rod 31 and the transmission member 20 is located outside the first housing 10. Correspondingly, the foot pedal interface 30 of the pedal assembly module 100 of the present application is located outside the first housing 10, which is convenient for the installation of the foot pedal 201 on the foot pedal interface 30 and avoids the first housing 10 affecting the installation space between the pedal assembly module 100 of the present application and the foot pedal 201. Thereby, the installation efficiency of the pedal assembly module 100 of the present application and the foot pedal 201 is improved.

[0163] In one embodiment, a foot pedal interface 30 includes a connecting rod 32 accommodated inside a first housing 10 of a pedal assembly module 100. One end of the connecting rod 32 is used for driving connection with a transmission member 20, and the other end of the connecting rod 32 is used for driving connection with a first end 31a of a pedal rod 31. A second end 31b of the pedal rod 31 is used for fixedly connecting with a foot pedal 201. For ease of description, the end of the connecting rod 32 drivingly connected with the transmission member 20 is defined as a third end 32a, and the end of the connecting rod 32 drivingly connected with the first end 31a of the pedal rod 31 is defined as a fourth end 32b.

[0164] Please refer to Figure 10 in conjunction with Figure 10 which is a schematic diagram of the connection structure of the foot pedal 201 in another embodiment of the pedal assembly 200 provided by the embodiment of the present application.

[0165] As Figure 10 shown, along the extension axis direction of the connecting rod 32, the third end 32a of the connecting rod 32 is farther from the foot pedal 201 than the fourth end 32b of the connecting rod 32. The first end 31a of the pedal rod 31 is accommodated inside the first housing 10 and is drivingly connected with the fourth end 32b of the connecting rod 32.

[0166] During the process of the user inputting a braking operation, the braking driving force applied by the user to the foot pedal 201 causes the pedal rod 31 to displace relative to the first housing 10, and successively drives the connecting rod 32 and the transmission member 20 to displace relative to the first housing 10. The transmission member 20 presses an elastic member inside the pedal feel simulator 202 through a push rod 50 and receives the rebounding force provided by the elastic member. The rebounding force is successively transmitted to the foot pedal 201 via the push rod 50, the transmission member 20, the connecting rod 32 and the pedal rod 31, and acts on the user to realize the elastic feedback of the user's braking operation.

[0167] In the embodiment of the present application, the first end 31a of the pedal rod 31 is located inside the first housing 10 and is drivingly connected with the fourth end 32b of the connecting rod 32. Since the second end 31b of the pedal rod 31 located outside the first housing 10 is fixedly connected with the foot pedal 201. When the foot pedal 201 is installed on the pedal assembly module 100 of the present application, the foot pedal 201 is installed on the pedal assembly module 100 of the present application through the driving connection between the pedal rod 31 and the connecting rod 32. That is to say, the foot pedal interface 30 of the pedal assembly module 100 of the present application is a structure for realizing the driving connection between the pedal rod 31 and the connecting rod 32.

[0168] Since the structure for realizing the transmission connection between the pedal rod 31 and the connecting rod 32 is located within the first housing 10. Correspondingly, the foot pedal interface 30 of the foot pedal assembly module 100 of the present application is located within the first housing 10, and the first housing 10 can protect the foot pedal interface 30, preventing external impurities from affecting the installation of the foot pedal 201 at the foot pedal interface 30. Thereby, the connection stability between the foot pedal assembly module 100 and the foot pedal 201 of the present application is ensured.

[0169] In one embodiment, a foot pedal 201 includes a pedal arm 2011, and the pedal arm 2011 is used to extend into a first housing 10 and fixedly connect with a connecting rod 32.

[0170] Please refer to Figure 11 , in which Figure 11 is a schematic diagram of the connection structure of the foot pedal 201 in another embodiment of the foot pedal assembly 200 provided by the embodiment of the present application.

[0171] As Figure 11 shown, one end of the pedal arm 2011 is used to receive the braking operation of the user, and the other end of the pedal arm 2011 is used to extend into the first housing 10 and fixedly connect with the connecting rod 32. For the convenience of description, it is defined that the end of the pedal arm 2011 outside the first housing 10 is the fifth end 2012, and the end of the pedal arm 2011 inside the first housing 10 is the sixth end 2013.

[0172] During the process of the user inputting a braking operation, the user steps on the fifth end 2012 of the pedal arm 2011 to apply a braking driving force to the pedal arm 2011. The braking driving force causes the pedal arm 2011 to displace relative to the first housing 10, and successively drives the connecting rod 32 and the transmission member 20 to displace relative to the first housing 10. The transmission member 20 presses an elastic member inside the pedal feel simulator 202 through the push rod 50 and receives the rebounding force provided by the elastic member. The rebounding force is successively transmitted to the pedal arm 2011 via the push rod 50, the transmission member 20, and the connecting rod 32, and acts on the user from the fifth end 2012 of the pedal arm 2011, realizing the elastic feedback to the user's braking operation.

[0173] In the embodiment of the present application, the sixth end 2013 of the pedal arm 2011 is located within the first housing 10 and fixedly connected to the fourth end 32b of the connecting rod 32. That is to say, the structure for realizing the fixed connection between the pedal arm 2011 and the connecting rod 32 is located within the first housing 10. Correspondingly, the foot pedal interface 30 of the foot pedal assembly module 100 of the present application is located within the first housing 10, and the first housing 10 can protect the foot pedal interface 30, preventing external impurities from affecting the installation of the foot pedal 201 at the foot pedal interface 30. Thereby, the connection stability between the foot pedal assembly module 100 and the foot pedal 201 of the present application is ensured.

[0174] In one embodiment, the first housing 10 of the pedal assembly module 100 includes two mounting surfaces. One of the pedal feel simulator interfaces 40 includes a mounting surface. One mounting surface is used for fixedly connecting to the firewall 1007 of the vehicle and for fixedly connecting to the second housing 2021 of a pedal feel simulator 202. One mounting surface includes a through hole, and the through hole is used for a push rod 50 to pass through. A foot pedal interface 30 includes another mounting surface, and the other mounting surface includes another through hole, and the other through hole is used for a pedal rod 31 to pass through.

[0175] For ease of description, define the mounting surface of the pedal feel simulator interface 40 as the first mounting surface 41. Correspondingly, the through hole on the first mounting surface 41 is the first through hole 42. Define the mounting surface of the foot pedal interface 30 as the second mounting surface 33. Correspondingly, the through hole on the second mounting surface 33 is the second through hole 34.

[0176] Please refer to Figures 12 - 14 , where Figure 12 is a schematic diagram of the external structure of the pedal assembly module 100 provided by an embodiment of the present application from one perspective, Figure 13 is a schematic diagram of the external structure of the pedal assembly module 100 provided by an embodiment of the present application from another perspective, Figure 14 is a schematic cross-sectional structure diagram of the pedal assembly module 100 provided by an embodiment of the present application.

[0177] As Figures 12 - 14 shown, the pedal assembly module 100 of the present application is accommodated in the passenger compartment of the vehicle. The pedal feel simulator 202 is installed in the front compartment of the vehicle through the first mounting surface 41 to reduce the space occupied by the pedal assembly 200 in the passenger compartment. The foot pedal 201 is installed in the passenger compartment of the vehicle through the second mounting surface 33, facilitating the user to input a braking operation.

[0178] Since when the user inputs a braking operation, the user usually steps on the foot pedal 201 such that the foot pedal 201 moves towards the first mounting surface 41. The pedal assembly module 100 of the present application is fixedly connected to the firewall 1007 of the vehicle through the first mounting surface 41 to reduce the space occupied by the pedal assembly 200 on the side of the passenger compartment away from the firewall 1007. Compared with the prior art in which the pedal feel simulator is arranged in the passenger compartment of the vehicle, the user of the pedal assembly module 100 of the present application has a relatively large activity space when stepping on the foot pedal 201, enabling the user to have a relatively long braking stroke during braking, facilitating the user to input a braking operation on the foot pedal 201, and improving the user experience.

[0179] On the other hand, since the front compartment of the vehicle is relatively enclosed compared to the passenger compartment of the vehicle, the footrest 201 and the pedal assembly module 100 of the present application are both accommodated in the passenger compartment of the vehicle, so that the footrest interface 30 of the pedal assembly module 100 of the present application is also accommodated in the passenger compartment of the vehicle, facilitating the replacement of the footrest 201 connected to the pedal assembly module 100. That is, the footrest 201 is located in the passenger compartment of the vehicle, facilitating the installation and replacement of the footrest 201.

[0180] In one embodiment, the orientations of the first mounting surface 41 and the second mounting surface 33 are perpendicular to each other. The first through hole 42 penetrates the first mounting surface 41 along the orientation of the first mounting surface 41, and the second through hole 34 penetrates the second mounting surface 33 along the orientation of the second mounting surface 33. Among them, the first mounting surface 41 is used to face the front compartment of the vehicle. Along the axial direction of the push rod 50, one end of the push rod 50 is located in the front compartment of the vehicle and extends into the second housing 2021, and is in transmission connection with the elastic member of the pedal feel simulator 202. The other end of the push rod 50 passes through the first through hole 42 along the axial direction of the push rod 50 and is located in the passenger compartment of the vehicle to be in transmission connection with the transmission member 20. That is, the push rod 50 axially passes through the first through hole 42 to be in transmission connection with the transmission member 20 and the elastic member of the pedal feel simulator.

[0181] In one embodiment, the second mounting surface 33 is used to face the lower part of the passenger compartment. The pedal rod 31 passes through the second through hole 34 and is in transmission connection between the footrest 201 and the transmission member 20. That is, the pedal assembly module 100 of the present application avoids the transmission connection between the footrest 201 and the transmission member 20 through the second through hole 34, and when the user inputs a braking operation, it is ensured that the pedal rod 31 can displace relative to the first housing 10 in the second through hole 34. This facilitates the transmission of the braking driving force applied by the user to the footrest 201 into the pedal feel simulator 202.

[0182] In one embodiment, the pedal assembly module 100 includes one push rod 50. One push rod 50 is used to extend out of the first housing 10 from the first through hole 42 and is in transmission connection with one or more elastic members in one pedal feel simulator 202.

[0183] In one embodiment, one pedal feel simulator 202 includes one push rod. One push rod is used to pass through the first through hole 42 and extend into the first housing 10 and is in transmission connection with one transmission member 20.

[0184] In one embodiment, the first through hole 42 includes two sections along the axial direction. One section is closer to the first mounting surface 41 than the other section, and the inner diameter of one section is larger than that of the other section. For the convenience of description, the section of the first through hole 42 relatively close to the first mounting surface 41 is defined as the first section 42a, and the section of the first through hole 42 relatively far from the first mounting surface 41 is defined as the second section 42b.

[0185] Please refer to Figure 15 and Figure 16 , where Figure 15 is a partial sectional structural schematic diagram of the pedal assembly 200 provided by the embodiment of the present application, Figure 16 is a partial sectional structural schematic diagram of the pedal assembly module 100 provided by the embodiment of the present application.

[0186] As Figure 15 and Figure 16 shown, the first section 42a of the first through hole 42 of the pedal assembly module 100 of the present application is used to allow the second housing 2021 of the pedal feel simulator 202 to extend therein, and the inner peripheral surface of the first section 42a is used to be fixedly connected to the outer peripheral surface of the second housing 2021. That is, the pedal feel simulator interface 40 of the pedal assembly module 100 of the present application is fixedly connected to the second housing 2021 of the pedal feel simulator 202 through the first section 42a of the first through hole 42 to realize the installation of the pedal assembly module 100 of the present application and the pedal feel simulator 202.

[0187] Along the radial direction of the first through hole 42, the inner diameter of the second section 42b is smaller than the outer diameter of the second housing 2021 of the pedal feel simulator 202, and the second section 42b of the first through hole 42 is used to block the second housing 2021 of the pedal feel simulator 202 from extending into the second section 42b. To avoid the phenomenon that the pedal feel simulator 202 passes through the first through hole 42 and extends into the first housing 10 to occupy the space inside the first housing 10 on the premise of ensuring the fixed connection between the first section 42a of the first through hole 42 and the second housing 2021. Thus, the pedal assembly module 100 of the present application has a relatively small volume, which is beneficial to the miniaturization of the pedal assembly module 100 of the present application.

[0188] In the embodiment of the present application, the second section 42b of the first through hole 42 is also used to allow the push rod 50 to extend therein. That is, along the axial direction of the push rod 50, one end of the push rod 50 is in transmission connection with the transmission member 20, and the other end of the push rod 50 passes through the second section 42b of the first through hole 42 and extends into the second housing 2021 accommodated in the first section 42a and is connected to the elastic member inside the second housing 2021. Thereby ensuring that the push rod 50 can transmit the braking driving force transmitted to the transmission member 20 to the pedal feel simulator 202 when the user inputs a braking operation, and transmit the rebound force provided by the compressed elastic member to the transmission member 20 to realize the elastic feedback of the user's braking operation.

[0189] On the other hand, the inner diameter of the second section 42b of the first through hole 42 is smaller than that of the first section 42a of the first through hole 42, so that the inner peripheral surface of the second section 42b can cooperate with the outer peripheral surface of the push rod 50 to reduce the radial clearance between the second section 42b and the push rod 50, thereby reducing the entry of external impurities into the first housing 10 through the first through hole 42, and thus protecting the structure of the pedal assembly module 100 accommodated in the first housing 10. That is to say, the pedal feel simulator interface 40 of the pedal assembly module 100 of the present application reduces the clearance between the two through the cooperation of the inner peripheral surface of the second section 42b of the first through hole 42 and the outer peripheral surface of the push rod 50 to protect the interior of the first housing 10.

[0190] In one embodiment, the inner diameter of the second section 42b of the first through hole 42 is equal to the outer diameter of a push rod 50. The inner peripheral surface of the second section 42b of the first through hole 42 is used to contact the outer peripheral surface of the push rod 50 to eliminate the radial clearance between the second section 42b and the push rod 50, thereby blocking the entry of external impurities into the first housing 10 through the first through hole 42 and protecting the structure inside the pedal assembly module 100 accommodated in the first housing 10. That is to say, the second section 42b of the first through hole 42 is used to cooperate with the push rod 50 to seal the interior of the first housing 10.

[0191] On the other hand, the outer peripheral surface of the push rod 50 contacts the inner peripheral surface of the second section 42b, so that the second section 42b of the first through hole 42 can limit the radial displacement of the push rod 50, so as to avoid the phenomenon that when the transmission member 20 transmits the braking driving force to the push rod 50 during the user's input of a braking operation, the push rod 50 will generate a displacement along its own radial direction, resulting in the elastic force stored in the elastic member not corresponding to the braking driving force released by the user driving the foot pedal 201. That is to say, the second section 42b of the first through hole 42 is used to limit the radial displacement of the push rod 50, ensuring reliable transmission between the push rod 50 and the transmission member 20 during the user's input of a braking operation.

[0192] In one embodiment, the inner peripheral surface of the first through hole 42 includes a plurality of mounting shoulders 421, each mounting shoulder 421 includes an axial section 4211 and a circumferential section 4212. Along the axial direction of the first through hole 42, one end of an axial section 4211 is located on the first mounting surface 41, and the other end of an axial section 4211 is used to communicate with a circumferential section 4212. Along the circumferential direction of the first through hole 42, the axial sections 4211 are arranged at intervals, and each circumferential section 4212 is located on the same side of an axial section 4211 with which it communicates.

[0193] Please refer to Figures 17 - 19 , in which Figure 17 is a schematic diagram of the external shape structure of the first housing 10 of the pedal assembly module 100 provided by the embodiment of the present application, Figure 18A partial cross-sectional structural schematic diagram of the first housing 10 of the pedal assembly module 100 provided by the embodiment of the present application. Figure 19 An external structural schematic diagram of the pedal feel simulator 202 of the pedal assembly 200 provided by the embodiment of the present application.

[0194] As Figures 17 - 19 Shown in the figure, a plurality of mounting stops 421 are all located in the first section 42a of the first through hole 42. The plurality of mounting stops 421 are used to fix the second housing 2021 of the pedal feel simulator 202. Among them, the outer peripheral surface of the second housing 2021 of the pedal feel simulator 202 includes a plurality of mounting protrusions 2022, and each mounting protrusion 2022 is respectively arranged in matching with a mounting stop 421, so that each mounting stop 421 can embed a mounting protrusion 2022, thereby realizing the fixed connection between the second housing 2021 and the inner peripheral surface of the first through hole 42.

[0195] When installing the pedal feel simulator 202 into the plurality of mounting stops 421, it is necessary to first align each mounting protrusion 2022 of the second housing 2021 with the corresponding plurality of mounting stops 421, and extend the pedal feel simulator 202 into the first through hole 42 along the axial direction of the first through hole 42. Among them, each mounting protrusion 2022 respectively extends into the axial section 4211 of the corresponding mounting stop 421. Until each mounting protrusion 2022 extending into each axial section 4211 extends into the connection between each axial section 4211 and the corresponding circumferential section 4212. The second housing 2021 rotates by facing the side where each axial section 4211 communicates with the circumferential section 4212, so as to screw each mounting protrusion 2022 into the corresponding circumferential section 4212 respectively. Thus, the fixed connection between the first housing 10 of the pedal assembly module 100 of the present application and the second housing 2021 of the pedal feel simulator 202 is realized.

[0196] That is to say, each axial section 4211 is used to allow the second housing 2021 of a pedal feel simulator 202 to extend into the first through hole 42, and each circumferential section 4212 is used to allow the second housing 2021 of the pedal feel simulator 202 to rotate and be fixed in the first through hole 42. Since during the actual use of the pedal assembly module 100 of the present application, when the braking driving force applied by the user to the foot pedal 201 is transmitted to the pedal assembly module 100, the pedal assembly module 100 drives the push rod 50 to displace axially along the axial direction of the push rod 50 through the transmission member 20. And the axial displacement of the push rod 50 may drive the second housing 2021 to displace axially along the push rod 50.

[0197] In the embodiment of the present application, along the axial direction of the first through hole 42, the circumferential length of each axial segment 4211 is smaller than the circumferential length of the circumferential segment 4212 connected thereto. When the second housing 2021 of the pedal feel simulator 202 is fixed to the first housing 10 of the pedal assembly module 100 of the present application by extending and then rotating, each axial segment 4211 can limit the second housing 2021 from sliding out of the first through hole 42 along the axial direction of the first through hole 42. That is, the plurality of mounting protrusions 2022 of the second housing 2021 of the pedal feel simulator 202 will be restricted within the plurality of circumferential segments 4212 under the action of the plurality of mounting stops 421, thereby avoiding the influence of the axial braking driving force of the push rod 50 on the fixation between the second housing 2021 and the first housing 10.

[0198] On the other hand, the mounting stops 421 of the pedal assembly module 100 of the present application, through the connected axial segments 4211 and circumferential segments 4212, enable the second housing 2021 of the pedal feel simulator 202 to be fixedly connected to the first housing 10 only by extending and then rotating. Correspondingly, when it is necessary to replace the pedal feel simulator 202, the second housing 2021 of the pedal feel simulator 202 can also be disassembled by rotating and then extending. This simplifies the installation and disassembly processes of the pedal assembly module 100 and the pedal feel simulator 202 of the present application, facilitating the installation and replacement of the pedal feel simulator 202.

[0199] In one embodiment, along the axial direction of the first through hole 42, the distances between the plurality of circumferential segments 4212 and the first mounting surface 41 are equal. Wherein, the axial distance between each circumferential segment 4212 and the first mounting surface 41 is the axial width of the axial segment 4211 connected to the circumferential segment 4212. That is, along the axial direction of the first through hole 42, the axial widths of the plurality of axial segments 4211 are equal.

[0200] When installing the pedal feel simulator 202 in the plurality of mounting stops 421, the axial widths of the respective axial segments 4211 are used to define the depth to which the respective mounting protrusions 2022 of the second housing 2021 of the pedal feel simulator 202 extend into the first through hole 42. When there are at least two axial segments 4211 with unequal axial widths, the axial thicknesses of the respective mounting protrusions 2022 of the pedal feel simulator 202 also need to be adjusted correspondingly to match the corresponding mounting stops 421. During the installation process of the pedal feel simulator 202, the insertion posture of the pedal feel simulator 202 needs to be adjusted to ensure that the axial thickness of each mounting protrusion 2022 can match the axial width of the inserted axial segment 4211. This increases the installation difficulty of the second housing 2021 of the pedal feel simulator 202. On the other hand, the adjustment of the axial thicknesses of the respective mounting protrusions 2022 of the pedal feel simulator 202 also increases the manufacturing cost and is not conducive to the machining of the second housing 2021 of the pedal feel simulator 202.

[0201] Therefore, by controlling the axial widths of the respective axial segments 4211 of the pedal assembly module 100 of the present application to be equal, it is convenient for the second housing 2021 of the pedal feel simulator 202 to be installed in the plurality of mounting stops 421. On the other hand, the equal axial widths of the respective axial segments 4211 of the respective mounting stops 421 also facilitate the machining of the plurality of mounting stops 421 and the second housing 2021 of the pedal feel simulator 202.

[0202] In one embodiment, along the axial direction of the first through hole 42, the axial widths of the respective circumferential segments 4212 are equal. When the axial widths of at least two circumferential segments 4212 are not equal, the axial thicknesses of the respective mounting protrusions 2022 of the pedal feel simulator 202 also need to be adjusted correspondingly to match the corresponding mounting stops 421. During the installation process of the pedal feel simulator 202, the insertion attitude of the pedal feel simulator 202 needs to be adjusted to ensure that the axial thickness of each mounting protrusion 2022 can match the axial width of the circumferential segment 4212 into which it is screwed. Thereby, the installation difficulty of the second housing 2021 of the pedal feel simulator 202 is increased.

[0203] Therefore, by controlling the axial widths of the respective circumferential segments 4212 of the pedal assembly module 100 of the present application to be equal, it is convenient for the second housing 2021 of the pedal feel simulator 202 to be installed in the plurality of mounting stops 421 and convenient to control the angle at which the second housing 2021 of the pedal feel simulator 202 is screwed into the first through hole 42. On the other hand, the equal axial widths of the respective circumferential segments 4212 of the respective mounting stops 421 also facilitate the machining of the plurality of mounting stops 421.

[0204] In one embodiment, along the circumferential direction of the first through hole 42, the arc lengths of the plurality of circumferential segments 4212 are less than the distance between adjacent two axial segments 4211. That is, along the circumferential direction of the first through hole 42, the circumferential spacing between adjacent two axial segments 4211 is greater than the arc length of the circumferential segment 4212 located between the adjacent two axial segments 4211.

[0205] Along the circumferential direction of the first through hole 42, each circumferential segment 4212 includes a circumferential side wall 4213 away from the axial segment 4211 to which it communicates. During the process of installing the pedal feel simulator 202 in the plurality of mounting stops 421, the rotation angle of the respective mounting protrusions 2022 of the pedal feel simulator 202 screwed into each circumferential segment 4212 is limited by the position of the circumferential side wall 4213. That is, when installing the pedal feel simulator 202 on the first mounting surface 41, the circumferential side wall 4213 of each circumferential segment 4212 can cooperate to limit the rotation angle during the installation of the pedal feel simulator 202.

[0206] In one embodiment, along the circumferential direction of the first through hole 42, the arc lengths of each circumferential segment 4212 are equal. When there are at least two circumferential segments 4212 with unequal arc lengths, during the installation of the pedal feel simulator 202 within the plurality of mounting stops 421, the circumferential side wall 4213 of the circumferential segment 4212 with a relatively smaller arc length defines the maximum rotation angle when the pedal feel simulator 202 is installed. Correspondingly, the rotation angle of the pedal feel simulator 202 is also relatively small under the limitation of the circumferential side wall 4213 of the circumferential segment 4212 with a relatively smaller arc length. During the use of the pedal assembly 200 in this application, external vibrations may cause the second housing 2021 of the pedal feel simulator 202 to spin out of the circumferential segment 4212, resulting in the second housing 2021 of the pedal feel simulator 202 disengaging from the pedal assembly module 100 of this application.

[0207] Therefore, the pedal assembly module 100 of this application controls the equal arc lengths of each circumferential segment 4212 to ensure a relatively large range of rotation angles when the pedal feel simulator 202 is installed, thereby ensuring the reliable installation of the pedal assembly module 100 of this application and the pedal feel simulator 202. On the other hand, the equal arc lengths of each circumferential segment 4212 facilitate the machining of each mounting stop 421 on the premise that the circumferential side wall 4213 of each circumferential segment 4212 defines the rotation angle when the pedal feel simulator 202 is installed.

[0208] Based on the limitations of the above embodiments, the pedal assembly module 100 of this application enables the pedal feel simulator 202 to be fixed to the pedal assembly module 100 in a rotational snap - fit manner based on each mounting stop 421. In other embodiments, other fixing methods may also be adopted between the pedal assembly module 100 of this application and the pedal feel simulator 202. In one embodiment, at least one of threaded connection, riveting, and welding is used to fix the pedal assembly module 100 of this application and the pedal feel simulator 202.

[0209] In one embodiment, along the axial direction of a push rod 50, the difference between the length dimension of the second through hole 34 and that of a transmission member 20 is less than the maximum compression amount of one or more elastic members in a pedal feel simulator 202.

[0210] Please refer to Figure 20 for reference, where Figure 20 is a partially enlarged structural schematic diagram of an embodiment of the pedal assembly 200 provided by an embodiment of this application.

[0211] As shown in Figure 20As shown, the pedal rod 31 is outside the first housing 10. The transmission member 20 is configured to extend out of the second through hole 34 and be in transmission connection with the first end 31a of the pedal rod 31. The second end 31b of the pedal rod 31 is used for fixedly connecting to the foot pedal 201. When the user inputs a braking operation through the foot pedal 201, the pedal rod 31 moves relative to the first housing 10 toward the first mounting surface 41 along with the user's braking operation, and drives the transmission member 20 to also move toward the first mounting surface 41. At this time, the transmission member 20 can axially displace within the second through hole 34 under the action of the braking driving force along the axial direction of the push rod 50.

[0212] In the embodiment of the present application, the length dimension of the second through hole 34 is used to define the moving stroke of the transmission member 20. Along the axial direction of the push rod 50, the part of the transmission member 20 accommodated in the second through hole 34 includes two axial side walls, and one of the axial side walls is closer to the first mounting surface 41 than the other axial side wall. Before the user inputs a braking operation through the foot pedal 201, as Figure 20 shown, the axial side wall of the transmission member 20 that is relatively far from the first mounting surface 41 contacts the hole wall of the second through hole 34. At this time, the distance between the pedal rod 31 and the first mounting surface 41 along the axial direction of the push rod 50 is the largest.

[0213] During the process when the user inputs a braking operation through the foot pedal 201, as Figure 21 shown, along the axial direction of the push rod 50, the axial side wall of the transmission member 20 that is relatively far from the first mounting surface 41 separates from the hole wall of the second through hole 34, and the axial side wall of the transmission member 20 that is relatively close to the first mounting surface 41 gradually reduces the gap with the hole wall of the second through hole 34 along with the user's braking operation until this axial side wall contacts the hole wall of the second through hole 34. At this time, the distance between the pedal rod 31 and the first mounting surface 41 along the axial direction of the push rod 50 is the smallest.

[0214] Thus, along the axial direction of the push rod 50, the difference between the length dimensions of the second through hole 34 and the transmission member 20 is the moving stroke of the transmission member 20 within the second through hole 34. In the embodiment of the present application, the difference between the length dimensions of the second through hole 34 and the transmission member 20 is less than the maximum compression amount of the elastic member of the pedal feel simulator 202, so that the moving stroke of the transmission member 20 within the second through hole 34 is less than the maximum compression amount of the elastic member of the pedal feel simulator 202, avoiding the phenomenon that the elastic member is damaged due to excessive braking driving force absorbed when the transmission member 20 is at the maximum stroke. Thereby, the protection of the elastic force feedback function of the pedal feel simulator 202 by the pedal assembly module 100 of the present application is realized.

[0215] It should be noted that when there are multiple elastic members in a pedal feel simulator 202, along the axial direction of one push rod 50, the difference between the length dimensions of the second through hole 34 and one transmission member 20 is less than the sum of the maximum compression amounts of the multiple elastic members respectively.

[0216] In one embodiment, along the axial direction of a push rod 50, the difference between the length dimension of the second through hole 34 and that of a pedal rod 31 is less than the maximum compression amount of one or more elastic members in a pedal feel simulator 202.

[0217] Please refer to Figure 22 , where Figure 22 is a partially enlarged structural schematic diagram of another embodiment of the pedal assembly 200 provided by the embodiment of the present application.

[0218] In one embodiment, as Figure 22 shown, the pedal assembly module 100 includes a pedal rod 31, a transmission member 20, and a connecting rod 32. The first housing 10 is used to accommodate the transmission member 20 and the connecting rod 32 that are in transmission connection. The first end 31a of the pedal rod 31 is accommodated in the first housing 10 and is in transmission connection with the connecting rod 32. In another embodiment, the pedal assembly module 100 includes a pedal rod 31 and a transmission member 20. The first end 31a of the pedal rod 31 is accommodated in the first housing 10 and is in transmission connection with the transmission member 20.

[0219] In the embodiment of the present application, the second end 31b of the pedal rod 31 extends out of the second through hole 34 and is fixedly connected to the foot pedal 201. When the user inputs a braking operation through the foot pedal 201, the pedal rod 31 moves relative to the first housing 10 toward the first mounting surface 41 along with the user's braking operation. At this time, the pedal rod 31 can axially displace in the second through hole 34 under the action of the braking driving force.

[0220] The length dimension of the second through hole 34 is used to define the moving stroke of the pedal rod 31. Along the axial direction of the push rod 50, the part of the pedal rod 31 accommodated in the second through hole 34 includes two axial side walls, and one of the axial side walls is closer to the first mounting surface 41 than the other axial side wall. Before the user inputs a braking operation through the foot pedal 201, as Figure 22 shown, the axial side wall of the pedal rod 31 that is relatively far from the first mounting surface 41 contacts the hole wall of the second through hole 34. At this time, the distance between the pedal rod 31 and the first mounting surface 41 along the axial direction of the push rod 50 is the largest.

[0221] During the process of the user inputting a braking operation through the foot pedal 201, as Figure 23 shown, along the axial direction of the push rod 50, the axial side wall of the pedal rod 31 that is relatively far from the first mounting surface 41 separates from the hole wall of the second through hole 34, and the axial side wall of the pedal rod 31 that is relatively close to the first mounting surface 41 gradually reduces the gap with the hole wall of the second through hole 34 along with the user's braking operation until this axial side wall contacts the hole wall of the second through hole 34. At this time, the distance between the pedal rod 31 and the first mounting surface 41 along the axial direction of the push rod 50 is the smallest.

[0222] Therefore, along the axial direction of the push rod 50, the difference in the length dimensions between the second through hole 34 and the pedal rod 31 is the moving stroke of the pedal rod 31 within the second through hole 34. In the embodiment of the present application, the difference in the length dimensions between the second through hole 34 and the pedal rod 31 is less than the maximum compression amount of the elastic member of the pedal feel simulator 202, such that the moving stroke of the pedal rod 31 within the second through hole 34 is less than the maximum compression amount of the elastic member of the pedal feel simulator 202, avoiding the phenomenon that the elastic member is damaged due to excessive braking driving force absorbed when the pedal rod 31 is at the maximum stroke. Thus, the protection of the elastic force feedback function of the pedal feel simulator 202 by the pedal assembly module 100 of the present application is achieved.

[0223] It should be noted that when there are multiple elastic members in a pedal feel simulator 202, along the axial direction of one push rod 50, the difference in the length dimensions between the second through hole 34 and one pedal rod 31 is less than the sum of the maximum compression amounts of the multiple elastic members respectively.

[0224] In one embodiment, one foot pedal 201 includes one pedal arm 2011. Along the axial direction of one push rod 50, the difference in the length dimensions between the second through hole 34 and one pedal arm 2011 is less than the maximum compression amount of one or more elastic members in one pedal feel simulator 202. When there are multiple elastic members in one pedal feel simulator 202, along the axial direction of one push rod 50, the difference in the length dimensions between the second through hole 34 and one pedal arm 2011 is less than the sum of the maximum compression amounts of the multiple elastic members respectively.

[0225] Please refer to Figure 24 , in which Figure 24 is a partially enlarged structural schematic diagram of another embodiment of the pedal assembly 200 provided by the embodiment of the present application.

[0226] In one embodiment, as Figure 24 shown, the pedal assembly module 100 includes a transmission member 20 and a connecting rod 32. The first housing 10 is used to accommodate the transmission member 20 and the connecting rod 32 that are in transmission connection. The sixth end 2013 of the pedal arm 2011 is accommodated within the first housing 10 and is in transmission connection with the connecting rod 32. In another embodiment, the pedal assembly module 100 includes a transmission member 20, and the sixth end 2013 of the pedal arm 2011 is accommodated within the first housing 10 and is in transmission connection with the transmission member 20.

[0227] In the embodiment of the present application, the fifth end 2012 of the pedal arm 2011 extends out from the second through hole 34 to receive the braking operation of the user. When the user inputs a braking operation through the fifth end 2012 of the pedal arm 2011, the pedal arm 2011 moves relative to the first housing 10 towards the first mounting surface 41 along with the braking operation of the user. At this time, the pedal arm 2011 can displace axially along the push rod 50 within the second through hole 34 under the action of the braking driving force.

[0228] The length dimension of the second through hole 34 is used to define the moving stroke of the pedal arm 2011. Along the axial direction of the push rod 50, the part of the pedal arm 2011 received in the second through hole 34 includes two axial side walls, and one of the axial side walls is closer to the first mounting surface 41 than the other axial side wall. Before the user inputs a braking operation through the foot pedal 201, as Figure 24 shown, the axial side wall of the pedal arm 2011 that is relatively far from the first mounting surface 41 contacts the hole wall of the second through hole 34. At this time, the distance between the pedal arm 2011 and the first mounting surface 41 along the axial direction of the push rod 50 is the largest.

[0229] During the process that the user inputs a braking operation through the foot pedal 201, as Figure 25 shown, along the axial direction of the push rod 50, the axial side wall of the pedal arm 2011 that is relatively far from the first mounting surface 41 separates from the hole wall of the second through hole 34, and the axial side wall of the pedal arm 2011 that is relatively close to the first mounting surface 41 gradually reduces the gap with the hole wall of the second through hole 34 along with the braking operation of the user until this axial side wall contacts the hole wall of the second through hole 34. At this time, the distance between the pedal arm 2011 and the first mounting surface 41 along the axial direction of the push rod 50 is the smallest.

[0230] Thus, along the axial direction of the push rod 50, the difference between the length dimension of the second through hole 34 and that of the pedal arm 2011 is the moving stroke of the pedal arm 2011 in the second through hole 34. In the embodiment of the present application, the difference between the length dimension of the second through hole 34 and that of the pedal arm 2011 is less than the maximum compression amount of the elastic member of the pedal feel simulator 202, so that the moving stroke of the pedal arm 2011 in the second through hole 34 is less than the maximum compression amount of the elastic member of the pedal feel simulator 202, avoiding the phenomenon that the elastic member is damaged due to excessive braking driving force absorbed when the pedal arm 2011 is at the maximum stroke. Thus, the protection of the elastic force feedback function of the pedal feel simulator 202 by the pedal assembly module 100 of the present application is realized.

[0231] In one embodiment, the first end 31a of a pedal rod 31 includes a slide rail 311, and a pedal rod 31 is used to be drivingly connected to a transmission member 20 through a slide rail 311. When a push rod 50 does not press a pedal feel simulator 202, the extending direction of a slide rail 311 is parallel to the axial direction of a push rod 50.

[0232] Please refer to Figures 26 - 28 for cooperation, in which Figure 26 is a schematic cross-sectional structure diagram of the connection between the transmission member 20 and the pedal rod 31 in the pedal assembly module 100 provided by the embodiment of the present application, Figure 27 is a schematic partial external shape structure diagram of the transmission member 20 in the pedal assembly module 100 provided by the embodiment of the present application, Figure 28Schematic diagram of the partial external structure of the pedal rod 31 in the pedal assembly module 100 provided by the embodiments of the present application.

[0233] As Figures 26 - 28 shown, the pedal assembly module 100 includes a transmission member 20. The transmission member 20 includes a chute 21. When the push rod 50 does not press the pedal feel simulator 202, the extending direction of the chute 21 is parallel to the axial direction of the push rod 50. The extending direction of the chute 21 is parallel to the extending direction of the slide rail 311. The chute 21 is used to match the slide rail 311 to realize the installation of the pedal rod 31 and the transmission member 20. That is, during the process of the user inputting a braking operation through the foot pedal 201, the braking driving force transmitted by the user from the foot pedal 201 to the pedal rod 31 can be transmitted into the transmission member 20 based on the mutual cooperation between the slide rail 311 and the chute 21.

[0234] In one embodiment, along the radial direction of a push rod 50, a slide rail 311 includes a protrusion 3111. The protrusion 3111 is used to extend towards the direction of a transmission member 20. When a push rod 50 does not press a pedal feel simulator 202, along the axial direction of a push rod 50, the protrusion 3111 includes a contact surface facing the first mounting surface 41. The distance between the contact surface and the first mounting surface 41 is less than the distance between the slide rail 311 and the first mounting surface 41. The contact surface includes a bolt hole 3112. The first end 31a of a pedal rod 31 is used to be fixedly connected to a transmission member 20 through a bolt hole 3112. For the convenience of description, the contact surface on the protrusion 3111 is defined as the first contact surface 3113.

[0235] As Figures 26 - 28 shown, along the radial direction of the push rod 50, the protrusion 3111 of the slide rail 311 is used to be embedded in the bottom 211 of the chute 21 and is in contact with the transmission member 20 along the axial direction of the push rod 50. Among them, the bottom 211 of the chute 21 includes a limiting groove 212. The limiting groove 212 is used to embed the protrusion 3111 of the slide rail 311. When a push rod 50 does not press a pedal feel simulator 202, along the axial direction of a push rod 50, the limiting groove 212 includes another contact surface in contact with the protrusion 3111 of the slide rail 311. The other contact surface faces away from the first mounting surface 41. For the convenience of description, the contact surface on the limiting groove 212 is defined as the second contact surface 213.

[0236] During the installation of the pedal rod 31 and the transmission member 20, the slide rail 311 slides into the chute 21 along the axial direction of the push rod 50, and the protrusion 3111 is embedded in the limiting groove 212. When a push rod 50 does not press a pedal feel simulator 202, along the axial direction of the push rod 50, the first contact surface 3113 of the protrusion 3111 embedded in the limiting groove 212 is in contact with the second contact surface 213 of the limiting groove 212.

[0237] When the user inputs a braking operation through the foot pedal 201, the braking driving force transmitted by the user from the foot pedal 201 to the pedal rod 31 can be transmitted into the transmission member 20 through the abutting relationship between the protrusion 3111 and the limiting groove 212. That is, the abutting relationship between the protrusion 3111 and the limiting groove 212 restricts the axial sliding of the pedal rod 31, and enables the braking driving force applied by the user to the foot pedal 201 to be reliably transmitted into the transmission member 20 after being transmitted to the pedal rod 31.

[0238] In the embodiment of the present application, the second abutting surface 213 includes a communication hole 214. During the installation of the pedal rod 31 and the transmission member 20, the communication hole 214 and the bolt hole 3112 communicate with each other as the first abutting surface 3113 abuts against the second abutting surface 213. The pedal assembly module 100 of the present application further includes a bolt 80. The bolt 80 realizes the fixed connection between the pedal rod 31 and the transmission member 20 through the mutually communicating communication hole 214 and bolt hole 3112. Thereby ensuring that the braking driving force of the user's braking operation transmitted to the pedal rod 31 can be reliably transmitted into the transmission member 20.

[0239] Based on the descriptions of the above two embodiments, in another embodiment, the pedal assembly module 100 includes a transmission member 20 and a connecting rod 32 that are in transmission connection with each other, and the pedal rod 31 is in transmission connection with the connecting rod 32. At this time, the connecting rod 32 includes a chute. The chute is used to match the slide rail 311 to realize the installation of the pedal rod 31 and the connecting rod 32. Correspondingly, the protrusion 3111 of the slide rail 311 is used to embed into the bottom of the chute of the connecting rod 32 and abut against the connecting rod 32 along the axial direction of the push rod 50. The abutting surface of the connecting rod 32 in contact with the slide rail 311 includes a communication hole. During the installation of the pedal rod 31 and the connecting rod 32, the communication hole and the bolt hole 3112 communicate with each other, and the bolt 80 realizes the fixed connection between the pedal rod 31 and the connecting rod 32 through the mutually communicating communication hole and bolt hole 3112. Thereby ensuring that the braking driving force of the user's braking operation transmitted to the pedal rod 31 can be reliably transmitted into the connecting rod 32.

[0240] Based on the limitations in the above embodiments, the pedal assembly module 100 of the present application realizes the fixed connection between the foot pedal 201 and the pedal assembly module 100 by sliding the slide rail 311 into the chute 21 and cooperating with the bolt 80. In other embodiments, other fixed connection methods can also be adopted between the pedal assembly module 100 and the foot pedal 201 of the present application. In one embodiment, the pedal assembly module 100 and the foot pedal 201 of the present application are fixedly connected by riveting and / or welding.

[0241] In one embodiment, a transmission member 20 includes a rotating arm 22. One end of the rotating arm 22 is used for rotatably connecting to the first housing 10 of the pedal assembly module 100. The other end of the rotating arm 22 is used for drivingly connecting to a foot pedal 201. The middle section 221 of the rotating arm 22 is used for abutting against a push rod 50 along the axial direction of the push rod 50. For ease of description, the end of the rotating arm 22 that is rotatably connected to the first housing 10 is defined as the seventh end 22a, and the end of the rotating arm 22 that is drivingly connected to the foot pedal 201 is defined as the eighth end 22b.

[0242] Please refer to Figure 29 , where Figure 29 is a schematic cross-sectional structure diagram of the pedal assembly module 100 provided by the embodiment of the present application.

[0243] As Figure 29 shown, the eighth end 22b of the rotating arm 22 is used for fixedly connecting to the pedal rod 31. When the user inputs a braking operation through the foot pedal 201, both the pedal rod 31 and the eighth end 22b of the rotating arm 22 rotate synchronously around the seventh end 22a of the rotating arm 22 towards the first mounting surface 41 following the user's braking operation, and drive the middle section 221 of the rotating arm 22 to rotate towards the first mounting surface 41. The middle section 221 of the rotating arm 22 synchronously pushes the push rod 50 to slide along the axial direction of the push rod 50, and squeezes the elastic member of the pedal feel simulator 202. Thereby, the braking driving force applied by the user on the foot pedal 201 is transmitted into the pedal feel simulator 202.

[0244] In one embodiment, a rotating arm 22 and a connecting rod 32 are of an integral structure. That is, the eighth end 22b of the rotating arm 22 is used for drivingly connecting to the foot pedal 201 through the pedal rod 31. Alternatively, the third end 32a of the connecting rod 32 is used for rotatably connecting to the first housing 10 of the pedal assembly module 100. In the embodiment of the present application, the rotating arm 22 and the connecting rod 32 are of an integral structure, which simplifies the force transmission path within the pedal assembly module 100 of the present application on the premise of ensuring that the pedal assembly module 100 of the present application can transmit the braking driving force applied by the user on the foot pedal 201 to the pedal feel simulator 202. Thereby, the manufacturing cost of the pedal assembly module 100 of the present application is reduced.

[0245] In one embodiment, the eighth end 22b of a rotating arm 22 is used for extending out of the first housing 10 and fixedly connecting to a pedal rod 31. In another embodiment, the eighth end 22b of a rotating arm 22 is used for extending out of the first housing 10 and fixedly connecting to a foot pedal 201.

[0246] Therefore, based on the limitations of the above embodiments, the pedal assembly module 100 of the present application installs the foot pedal 201 through the foot pedal interface 30, and installs the pedal feel simulator 202 through the pedal feel simulator interface 40 to form a pedal assembly 200, so that the braking driving force applied by the user to the foot pedal 201 can be transmitted to the transmission member 20 through the foot pedal interface 30, and the transmission member 20 drives the push rod 50 to squeeze the elastic member of the pedal feel simulator 202. The transmission member 20 is also used to receive the rebound force transmitted by the elastic member of the pedal feel simulator 202 through the push rod 50 and transmit the rebound force to the foot pedal 201 to realize the elastic feedback of the user's braking operation.

[0247] In the above process, the pedal assembly module 100 of the present application also senses the user's braking operation through the first sensor 60 housed in the first housing 10 and outputs a first stroke signal or a first pressure signal to reflect the user's braking operation.

[0248] On the other hand, the pedal assembly module 100 of the present application realizes the independent installation of the pedal feel simulator 202 and the foot pedal 201 respectively, so as to facilitate the replacement of different pedal feel simulators 202 to meet the user's needs when different users have different requirements for the rebound force provided by the pedal feel simulator 202. And when different users have different requirements for the position, material or appearance of the foot pedal 201, it is convenient to replace different foot pedals 201 to meet the user's needs. That is to say, the pedal assembly module 100 of the present application facilitates the replacement of the pedal feel simulator 202 and the foot pedal 201 based on different user needs to improve the user experience.

[0249] When the pedal assembly module 100 of the present application is assembled with the pedal feel simulator 202 and the foot pedal 201 to form a pedal assembly 200, the pedal assembly 200 of the present application facilitates the replacement of the pedal feel simulator 202 and the foot pedal 201 based on different user needs to improve the user experience. When the pedal assembly 200 of the present application is applied to the braking system 1002, the first stroke signal or the first pressure signal output by the pedal assembly module 100 of the present application can act on the braking motor 1005 of the electromechanical braking device 1004, and the braking motor 1005 drives the friction plate in the brake 1006 to abut against the brake disc 1003, thereby realizing the braking function of the vehicle. On the other hand, the braking system 1002 of the present application also facilitates the replacement of the pedal feel simulator 202 and the foot pedal 201 based on different user needs to improve the user experience.

[0250] When the braking system 1002 of the present application is applied to a vehicle, the vehicle of the present application also facilitates the replacement of the pedal feel simulator 202 and the foot pedal 201 based on different user needs to improve the user experience.

[0251] The pedal assembly module 100 of the present application can also be applied to other usage scenarios where braking is achieved by using the braking operation of the user. Exemplarily, the structure of the pedal assembly module 100 of the present application is applied to machine tools, ships, construction machinery, etc. The present application does not make any special restrictions in this regard. In other usage scenarios, the structure of the pedal assembly module 100 of the present application also facilitates the replacement of the pedal feel simulator 202 and the foot pedal 201 based on different user requirements to improve the user experience.

[0252] In one embodiment, the pedal assembly module 100 includes a sensor interface 91, and a sensor interface 91 is used to install a transmission terminal 92. The first sensor 60 is used to output a stroke signal or a pressure signal through a transmission terminal 92.

[0253] Please refer to Figure 30 and Figure 31 where Figure 30 is a schematic diagram of the external structure of the pedal assembly module 100 provided by the embodiment of the present application from another perspective, Figure 31 is a schematic cross-sectional structure diagram of the pedal assembly module 100 provided by the embodiment of the present application.

[0254] As Figure 30 and Figure 31 shown, the pedal assembly module 100 further includes a transmission terminal 92. The transmission terminal 92 is used for electrically connecting with the first sensor 60, and the transmission terminal 92 is also used for communicating with an external circuit. In one embodiment, the transmission terminal 92 is used for communicating with the circuit board of the braking motor 1005. When the user inputs a braking operation through the foot pedal 201, the rotating arm 22 or the push rod 50 applies the braking driving force applied by the user to the foot pedal 201 to the first sensor 60. The first sensor 60 is used to detect the braking driving force transmitted by the rotating arm 22 or the push rod 50 and output a first pressure signal. The first pressure signal is output to the braking motor 1005 through the transmission terminal 92. The braking motor 1005 operates based on the first pressure signal transmitted by the transmission terminal 92 to drive the brake 1006 to brake the vehicle.

[0255] Alternatively, when the user inputs a braking operation through the foot pedal 201, the rotating arm 22 or the push rod 50 generates an axial displacement based on the braking driving force applied by the user to the foot pedal 201. The first sensor 60 is used to detect the axial displacement of the rotating arm 22 or the push rod 50 and output a first stroke signal. The first stroke signal is output to the braking motor 1005 through the transmission terminal 92. The braking motor 1005 operates based on the first pressure signal transmitted by the transmission terminal 92 to drive the brake 1006 to brake the vehicle.

[0256] That is, in the embodiment of the present application, the transmission terminal 92 is used to output the first pressure signal or the first stroke signal output by the first sensor 60 to reflect the user's braking intention. In one embodiment, the transmission terminal 92 is also used to electrically connect the second sensor, and to output the second pressure signal or the second stroke signal output by the second sensor to reflect the user's braking intention. On the other hand, when the first sensor 60 fails and cannot output the correct first stroke signal or the first pressure signal, the transmission terminal 92 can output the second stroke signal or the second pressure signal output by the second sensor to reflect the user's braking intention. When the second sensor fails and cannot output the correct second stroke signal or the second pressure signal, the transmission terminal 92 can output the first stroke signal or the first pressure signal output by the first sensor 60 to reflect the user's braking intention.

[0257] In one embodiment, a sensor interface 91 includes a third mounting surface 911, and the third mounting surface 911 includes a third through hole 912, and the third through hole 912 is used to pass a transmission terminal 92, so as to facilitate the electrical connection between a transmission terminal 92 and the first sensor 60. In the embodiment of the present application, the first housing 10 is used to accommodate the first sensor 60 to prevent external impurities from affecting the detection accuracy of the first sensor 60. That is, the setting of the third through hole 912 can ensure that the first pressure signal or the first stroke signal detected by the first sensor 60 can be transmitted to the outside world under the premise of reducing the influence of external impurities on the first sensor 60, so as to reflect the user's braking intention.

[0258] In one embodiment, the orientation of the third mounting surface 911 is perpendicular to the orientation of the first mounting surface 41 and opposite to the orientation of the second mounting surface 33. A third through hole 912 penetrates the third mounting surface 911 along the direction of the third mounting surface 911, so that a transmission terminal 92 connected to communicate with an external circuit passes through the first shell 10 and is electrically connected to the first sensor 60.

[0259] The third mounting surface 911 faces the upper side of the passenger compartment. In the embodiment of the present application, the orientation of the third mounting surface 911 is different from the orientation of the first mounting surface 41 and the orientation of the second mounting surface 33, so as to prevent the pedal feel simulator 202, the foot pedal 201 and part of the pedal assembly module 100 located outside the first housing 10 from affecting the transmission terminal 92 in transmitting the first pressure signal or the first stroke signal. This ensures that the transmission terminal 92 reliably transmits the first pressure signal or the first stroke signal.

[0260] In one embodiment, a controller 70 is connected to one or more electronic mechanical brake devices 1004 of the vehicle through a transmission terminal 92. A transmission terminal 92 is used to output a control signal of a controller 70.

[0261] Please refer to Figure 32 , in which Figure 32 is a schematic diagram of the working process of the pedal assembly provided by the embodiment of the present application.

[0262] As Figure 32 shown, the controller 70 is electrically connected to the first sensor 60 and the second sensor respectively. During the process of the user inputting a braking operation, the first sensor 60 outputs a first stroke signal or a first pressure signal, and the second sensor outputs a second stroke signal or a second pressure signal. The controller 70 is configured to receive the first stroke signal or the first pressure signal output by the first sensor 60, and receive the second stroke signal or the second pressure signal output by the second sensor. At this time, the first stroke signal, the first pressure signal, the second stroke signal, or the second pressure signal can all reflect the user's braking operation. The first stroke signal or the first pressure signal of the first sensor 60 can cooperate with the first stroke signal or the second pressure signal of the second sensor to form control redundancy, so as to improve the reliability of the pedal assembly 200.

[0263] When the user inputs a braking operation to the foot pedal 201, the controller 70 can selectively respond to one of the first stroke signal or the first pressure signal output by the first sensor 60 and the second stroke signal or the second pressure signal output by the second sensor to output a control signal. And transmit the control signal to the braking motor 1005 of the electromechanical braking device 1004 via the transmission terminal 92. Thus, the control of the braking motor 1005 is realized.

[0264] That is to say, after the controller 70 receives the first stroke signal or the first pressure signal output by the first sensor 60 and the second stroke signal or the second pressure signal output by the second sensor, the controller 70 can input and process by selecting the stroke signal or the pressure signal output by one of the sensors to eliminate control redundancy, and output a control signal to the braking motor 1005 via the transmission terminal 92 based on the above-mentioned stroke signal or pressure signal, so as to facilitate the braking motor 1005 to drive the brake 1006 to meet the user's braking requirements.

[0265] In one embodiment, during the process of receiving the first stroke signal or the first pressure signal of the first sensor 60 and the second stroke signal or the second pressure signal of the second sensor, the controller 70 is further configured to compare the error between the first stroke signal or the first pressure signal of the first sensor 60 and the second stroke signal or the second pressure signal of the second sensor, and when the error meets a preset condition, respond to the first pressure signal or the first stroke signal of the first sensor 60 to output a control signal. When the error does not meet the preset condition, the controller 70 responds to the one with a larger change amplitude among the first stroke signal or the first pressure signal output by the first sensor 60 and the second stroke signal or the second pressure signal output by the second sensor to output a control signal.

[0266] When the first sensor 60 and the second sensor acquire relevant data, there may be an error between the first stroke signal or the first pressure signal of the first sensor 60 and the second stroke signal or the second pressure signal of the second sensor. Since both the first sensor 60 and the second sensor are used to detect the user's braking operation, their power sources are the same. There is a mapping relationship between the first stroke signal or the first pressure signal of the first sensor 60 and the second stroke signal or the second pressure signal of the second sensor. Based on this mapping relationship, a preset condition can be set, and this preset condition is used to assist the controller 70 in comparing the error between the two, so as to determine whether the first sensor 60 and the second sensor are in a normal state.

[0267] Among them, when the error between the first stroke signal or the first pressure signal of the first sensor 60 and the second stroke signal or the second pressure signal of the second sensor meets the preset condition, the controller 70 determines that both the first sensor 60 and the second sensor are in a normal state. At this time, both the first stroke signal or the first pressure signal of the first sensor and the second stroke signal or the second pressure signal of the second sensor can reflect the user's braking operation.

[0268] Since the first sensor 60 obtains the first stroke signal or the first pressure signal through the rotating arm 22 or the push rod 50, and the second sensor obtains the second stroke signal or the second pressure signal through the elastic member or the push rod 50. Also, because the second sensor is accommodated in the second housing 2021 of the pedal feel simulator 202, compared with the second sensor, the first sensor 60 is relatively closer to the foot pedal 201, so that the first stroke signal or the first pressure signal output by the first sensor 60 can more accurately reflect the user's braking intention.

[0269] For the second sensor, during the actual use of the pedal assembly 200 in this application, external vibrations may cause relative displacement between the pedal feel simulator 202 and the pedal assembly module 100 of this application, thereby affecting the output of the second stroke signal of the second sensor. On the other hand, during the axial sliding of the push rod 50 under the action of the braking driving force, it may also be affected by the friction of the second section 42b of the first through hole 42, thereby reducing the braking driving force received by the push rod 50 and the elastic member and affecting the output of the second pressure signal of the second sensor.

[0270] Thus, when the controller 70 determines that both the first sensor 60 and the second sensor are in a normal state, the controller 70 outputs a control signal based on the first stroke signal or the first pressure signal, enabling the controller 70 to more accurately identify the user's braking intention to achieve a better braking effect.

[0271] In the embodiment of this application, when the error between the first stroke signal or the first pressure signal of the first sensor 60 and the second stroke signal or the second pressure signal of the second sensor does not meet the preset condition, one of the first sensor 60 and the second sensor is in an abnormal state. For any sensor, when it is in an abnormal state, reliable detection data cannot be obtained or the detection data does not change. That is, the change amplitude of the stroke signal or the pressure signal output by the sensor in the abnormal state is smaller than that of the sensor in the normal state.

[0272] For safety considerations, to ensure that the control signal output by the controller 70 can better match the user's braking intention, the controller 70 responds to the one with a larger change amplitude among the first stroke signal or the first pressure signal of the first sensor 60 and the second stroke signal or the second pressure signal of the second sensor based on the above mapping relationship to output a control signal, thereby ensuring that the controller 70 can output a control signal based on the stroke signal or the pressure signal output by the normal one of the first sensor 60 and the second sensor, avoiding potential safety hazards caused by insufficient vehicle braking due to the control signal output by the controller 70.

[0273] In another embodiment, when the error between the first stroke signal or the first pressure signal of the first sensor 60 and the second stroke signal or the second pressure signal of the second sensor meets the preset condition, the controller 70 responds to the second pressure signal or the second stroke signal of the second sensor to output a control signal.

[0274] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the protection scope of this application. Thus, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalent technologies, this application also intends to include these modifications and variations.
