For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] At present, vehicles have been widely popularized in ordinary families and integrated into people's daily lives. People use vehicles to travel more and more frequently. Thanks to the multiple advantages of new energy vehicles such as cost-effectiveness, environmental protection and advanced technology, new energy vehicles have become one of the mainstream choices in the vehicle consumer market.

[0034] New energy vehicles, such as pure electric vehicles and extended-range vehicles, have undergone unprecedented changes in electronic and electrical architecture compared to traditional fuel vehicles. For example, the distributed architecture has been transformed into a more efficient domain-centralized architecture, the smart cockpit has integrated a variety of advanced human-computer interaction technologies, and the application of assisted driving technologies has been applied. These demands for intelligence and automation have put forward higher requirements for the wire control of the vehicle chassis.

[0035] As the name implies, the chassis by wire is a system based on electrical signal control. It abandons the traditional mechanical connection and uses a variety of sensors and electronic control systems to convert the driver's physical actions into electrical signals, which are then transmitted to the corresponding actuators through the bus to achieve accurate and efficient management of the vehicle's dynamic behavior. In the chassis by wire technology, steering by wire, drive by wire, and brake by wire are becoming the focus of research.

[0036] In the related art, the vehicle's steering signal is obtained by the steering wheel, and the vehicle's braking and acceleration signals are obtained by the accelerator pedal and the brake pedal respectively. However, the steering wheel and the pedals occupy a large space inside the vehicle, resulting in a limited layout of other components inside the vehicle and limited space for personnel activities, which is not conducive to improving the comfort of personnel driving the vehicle and the convenience of the cockpit layout.

[0037] Based on the above problems, the present application proposes a vehicle operating component, a wire control system and a vehicle, aiming to solve the problem in the related art that the steering wheel and pedals occupy a large space inside the vehicle, resulting in limited space inside the vehicle.

[0038] In a first aspect, the present application provides an operating assembly 10 for a vehicle. Figure 1 and Figure 2As shown, the operating assembly 10 includes a base 100, a joystick 200, a first angle sensor 510, a second angle sensor 530 and a controller 2. The joystick 200 is connected to the base 100, and the joystick 200 can rotate relative to the base 100 with a first direction X as an axis to control the steering of the vehicle. The joystick 200 can also rotate relative to the base 100 with a second direction Y as an axis to control the driving state of the vehicle. The first angle sensor 510 is used to detect the angle of the joystick 200 when it rotates relative to the base 100 with the first direction X as an axis, and the second angle sensor 530 is used to detect the angle of the joystick 200 when it rotates relative to the base 100 with the second direction Y as an axis. The controller 2 is electrically connected to the first angle sensor 510 and the second angle sensor 530 respectively, and the first direction X, the second direction Y and the height direction Z of the vehicle are perpendicular to each other.

[0039] In the present application, the base 100 can be fixed on one side of the driver's seat in the vehicle, or the base 100 can be fixed at the position of the driver's seat where the steering wheel was originally set. The joystick 200 can rotate relative to the base 100 with the first direction X as the axis, and at the same time, the joystick 200 can also rotate relative to the base 100 with the second direction Y as the axis. In this way, when the driver drives the vehicle, the vehicle can be operated by holding the joystick 200. Among them, when holding the joystick 200 and rotating it with the first direction X as the axis, the vehicle can be turned left and right; when holding the joystick 200 and rotating it with the second direction Y as the axis, the vehicle can be accelerated, braked, etc.

[0040] It should be noted that in the related art, in the wire-controlled chassis technology using a steering wheel, an accelerator pedal and a brake pedal, the main function of the steering wheel is to provide the vehicle's controller with a steering wheel angle signal, and the controller then converts the above electrical signal into the vehicle's front wheel angle signal through an algorithm, and transmits it to the steering actuator, and then the steering motor realizes the steering of the wheels. The main function of the accelerator pedal is to provide the vehicle's controller with an accelerator pedal displacement signal, and the controller then converts the above electrical signal into the vehicle's driving torque signal through an algorithm, and transmits it to the driving actuator, and then the vehicle is accelerated through the driving motor. The main function of the brake pedal is to provide the vehicle's controller with a brake pedal displacement signal, and the controller then converts the above electrical signal into the vehicle's braking torque signal through an algorithm, and transmits it to the braking actuator, and then the vehicle is decelerated through the braking motor.

[0041] In the present application, the operating assembly 10 further includes a first angle sensor 510, a second angle sensor 530 and a controller 2, wherein the first angle sensor 510 is used to detect the angle of the joystick 200 when it rotates relative to the base 100 with the first direction X as the axis, and the second angle sensor 530 is used to detect the angle of the joystick 200 when it rotates relative to the base 100 with the second direction Y as the axis. In this way, when the joystick 200 rotates with the first direction X as the axis, the rotation angle of the joystick 200 and the steering wheel angle can be converted into a one-to-one correspondence by calibration. In this way, the rotation angle of the joystick 200 when it rotates with the first direction X as the axis can indirectly provide the controller 2 with a steering wheel angle signal, so that the joystick 200 replaces the steering wheel to achieve control of the vehicle steering.

[0042] Based on the same principle, the total angle of the joystick 200 rotating about the second direction Y as the axis can be divided into two parts, and the dividing line between the two parts is used as the 0° reference angle, and the two parts are respectively recorded as the first angle part and the second angle part. In this way, the rotation angle of the joystick 200 in the first angle part and the position change of the accelerator pedal can be converted into a one-to-one correspondence by calibration, and at the same time, the rotation angle of the joystick 200 in the second angle part and the position change of the brake pedal can be converted into a one-to-one correspondence by calibration. In this way, the rotation angle of the joystick 200 rotating about the second direction Y as the axis can indirectly provide the controller with an accelerator pedal displacement signal or a brake pedal displacement signal, so that the joystick 200 replaces the accelerator pedal and the brake pedal to achieve control of the vehicle state.

[0043] As a result, the operating component 10 of the present application can replace the functions of the steering wheel, accelerator pedal and brake pedal. In this way, on the first hand, the driving seat in the car does not need to be provided with structures such as a steering wheel, accelerator pedal and brake pedal, so as to save space in the car, and conveniently reserve the layout space of other components and the activity space of personnel, which is conducive to improving the driving comfort of personnel and the convenience of the cockpit layout. On the second hand, compared with structures such as a steering wheel, accelerator pedal and brake pedal, the base 100 and the joystick 200 are lighter in weight, more integrated, and easy to maintain, which is also conducive to improving the lightweight and reliability of the vehicle. On the third hand, personnel can control the driving form of the vehicle with one hand, thereby providing a relatively friendly control solution for special groups of people.

[0044] The above example lists a way to control the vehicle by using the joystick 200 instead of the steering wheel, accelerator pedal and brake pedal. In the above method, the angle signal of the joystick 200 rotating with the first direction X as the axis and the angle signal of the steering wheel are in a mutually converted and calibrated relationship, and the angle signal of the joystick 200 rotating with the second direction Y as the axis and the position signal of the accelerator pedal and the position signal of the brake pedal are in a mutually converted and calibrated relationship. The control logic of the joystick 200 on the vehicle state is that when the joystick 200 is operated, the angle signal of the joystick 200 can be first converted into the angle signal of the steering wheel, the position signal of the accelerator pedal, and the position signal of the brake pedal. Then, the above-mentioned converted control signal can be input into the controller in the original wire control system of the vehicle, and finally the controller realizes the control of the vehicle's steering, acceleration and deceleration and other states.

[0045] It is easy to understand that the joystick 200 can also be used in other ways to replace the steering wheel, the accelerator pedal and the brake pedal to control the vehicle. For example, the rotation angle of the joystick 200 when it rotates with the first direction X as the axis and the rotation angle when it rotates with the second direction Y as the axis can also be directly calibrated with the motion state of the vehicle, so that each angle value of the joystick 200 can correspond to a state of the vehicle, such as the acceleration magnitude during braking or acceleration, the front wheel angle magnitude, etc., thereby establishing a functional relationship between the angle of the joystick 200 and the state of the vehicle such as steering, acceleration, deceleration, etc. In this way, the control logic of the joystick 200 on the vehicle state is that when the joystick 200 is operated, the angle signal of the joystick 200 can be directly input into the controller 2 of the vehicle wire control system, and the controller 2 can directly obtain the front wheel angle of the vehicle, the acceleration magnitude during braking or acceleration, etc. based on the functional relationship established by the real vehicle calibration, thereby realizing the control of the state of the vehicle such as steering, acceleration and deceleration.

[0046] It is understandable that in this way, the rotation angle signal of the joystick 200 can be directly used as the input signal of the controller, making the control easier and more accurate. However, this method also requires re-establishing the function model between the motion state of the joystick 200 and the motion state of the vehicle, making the model building work complicated.

[0047] In some embodiments, Figure 2As shown, the operating component 10 also includes a first torque sensor 520, which is used to detect the torque when the joystick 200 rotates relative to the base 100 with the first direction X as the axis. In this way, the torque signal when the joystick 200 rotates with the first direction X as the axis can be obtained. In the related art, the steering wheel can also provide an angle torque signal to provide a "road feel" or "steering assist" for the steering wheel in the wire control system. Therefore, this embodiment can also calibrate the torque signal when the joystick 200 rotates with the first direction X as the axis and convert it into a torque signal of the steering wheel, or can directly perform actual vehicle test calibration, so that the joystick 200 can replace the steering wheel in all aspects, which is conducive to increasing the space inside the vehicle.

[0048] Optionally, in some embodiments, the first angle sensor 510 and the first torque sensor 520 are an integrated structure, that is, they are angle torque sensors that can detect the angle and the torque at the same time.

[0049] In some embodiments, Figure 2 As shown, the operating assembly 10 further includes a second torque sensor 540, which is used to detect the torque when the joystick 200 rotates relative to the base 100 with the second direction Y as the axis, and the controller 2 is also electrically connected to the second torque sensor 540. By providing the second torque sensor 540, the torque signal of the second torque sensor 540 can also be input into the controller 2, so that the rotation angle signal and the torque signal of the joystick 200 are simultaneously used as a determination condition for the magnitude of the vehicle acceleration, thereby facilitating the improvement of the accuracy of the joystick 200 in controlling the acceleration or deceleration of the vehicle.

[0050] In some embodiments, the first direction X is the front-to-back direction of the vehicle, and the second direction Y is the left-to-right direction of the vehicle. In this way, when the joystick 200 rotates with the first direction X as the axis, it is equivalent to the joystick 200 rotating to the left or right, and when the joystick 200 rotates with the second direction Y as the axis, it is equivalent to the joystick 200 rotating forward or backward. In other words, when the joystick 200 rotates to the left, the vehicle can turn left; when it rotates to the right, the vehicle can turn right; when it rotates forward, the vehicle can accelerate forward; when it rotates backward, the vehicle can brake and decelerate. In this way, the operating state of the joystick 200 is set to be consistent with the driving state of the vehicle, which is convenient for the driver to quickly adapt, helps to reduce the possibility of driver misoperation, and improves the safety of the driver.

[0051] In some embodiments, Figure 1As shown, the joystick 200 has an initial position, and the initial position of the joystick 200 divides the angle of the joystick 200 rotating with the first direction X as the axis into two parts, and at the same time divides the angle of the joystick 200 rotating with the second direction Y as the axis into two parts. Taking the first direction X as the front and rear direction of the vehicle and the second direction Y as the left and right direction of the vehicle as an example, the initial position of the joystick 200 can divide the angle of the joystick 200 rotating with the first direction X as the axis into a left rotation angle and a right rotation angle, and divide the angle of the joystick 200 rotating with the second direction Y as the axis into a front rotation angle and a rear rotation angle. In this way, the left rotation angle can correspond to the left steering angle of the steering wheel, the right rotation angle can correspond to the right steering angle of the steering wheel, the front rotation angle can correspond to the displacement size of the accelerator pedal, and the rear rotation angle can correspond to the displacement size of the brake pedal. In this way, on the one hand, it is conducive to improving the convenience of calibrating between the joystick 200 and the driving state of the vehicle, and on the other hand, it is also conducive to improving the accuracy of vehicle control.

[0052] Further, the joystick 200 can swing relative to the base 100 at the initial position with the first direction X as the axis, and the angle of the swing relative to the base 10 at the initial position is less than 90°. In this embodiment, taking the first direction X as the front-to-back direction of the vehicle as an example, the joystick 200 can swing relative to the base 100 at the initial position with the first direction X as the axis means that the joystick 200 can rotate to the left at the initial position, and can also rotate to the right at the initial position. Further, the angle of the swing of the joystick 200 relative to the base 10 at the initial position is less than 90°, that is, the left rotation angle and the right rotation angle of the joystick 200 are both less than 90°. In this way, the swing angle of the joystick 200 with the first direction X as the axis will not be too large, thereby facilitating the driver's control and improving the control comfort.

[0053] Further, the joystick 200 can swing relative to the base 100 at the initial position with the second direction Y as the axis, and the angle of the swing relative to the base 10 at the initial position is less than 90°. In this embodiment, taking the second direction Y as the left and right direction of the vehicle as an example, the joystick 200 can swing relative to the base 100 at the initial position with the second direction Y as the axis means that the joystick 200 can rotate forward at the initial position, and can also rotate backward at the initial position. Further, the angle of the swing of the joystick 200 relative to the base 10 at the initial position is less than 90°, that is, the front rotation angle and the rear rotation angle of the joystick 200 are both less than 90°. In this way, the swing angle of the joystick 200 with the second direction Y as the axis will not be too large, thereby facilitating the driver's control and improving the control comfort.

[0054] In some embodiments, Figure 3 and Figure 4As shown, the base 100 includes a first shell 110 and a second shell 120, the joystick 200 is connected to the second shell 120, the second shell 120 is located inside the first shell 110, the first shell 110 is provided with a first matching portion 111 on both side walls along the first direction X, and the second shell 120 is provided with a second matching portion 121 on both side walls along the first direction X, the first matching portion 111 and the second matching portion 121 are rotatably connected, so that the second shell 120 can rotate relative to the first shell 110 with the first direction X as the axis. In this way, the joystick 200 can be rotated relative to the base 100 with the first direction X as the axis. Among them, the first matching portion 111 can be, for example, a pin hole provided on the inner wall of the first shell 110, and the second matching portion 121 can be, for example, a pin column provided on the outer wall of the second shell 120, and the pin column can rotate in the pin hole. Of course, the first matching portion 111 may also be a pin column, and the second matching portion 121 may be a pin hole; or, the first matching portion 111 and the second matching portion 121 may also be other structures, and the present application does not limit this, as long as the joystick 200 can be rotated relative to the base 100 with the first direction X as the axis.

[0055] In some embodiments, Figure 5 and Figure 6 As shown, the joystick 200 includes a hand-held portion 210, a transition portion 220 and a connecting portion 230. The connecting portion 230 is located inside the second shell 120. A third matching portion 122 is provided on the two side walls of the second shell 120 along the second direction Y. A fourth matching portion 231 is provided on the two side walls of the connecting portion 230 along the second direction Y. The third matching portion 122 is rotatably connected with the fourth matching portion 231 so that the connecting portion 230 can rotate relative to the second shell 120 with the second direction Y as the axis.

[0056] The joystick 200 includes a handheld portion 210, a transition portion 220, and a connecting portion 230. The joystick 200 can be made of a lightweight metal alloy material to improve its strength and durability and reduce its weight. The handheld portion 210 is used for holding by a human hand. The handheld portion 210 can be designed to fit the contour of a person's hand, for example. A hand rest 211 can also be provided on the handheld portion 210 to reduce the driver's hand fatigue and maintain a natural grip. A rubber or silicone sleeve can be provided on the outside of the handheld portion 210 to improve the grip feel. The transition portion 220 is used to connect the handheld portion 210 and the connecting portion 230. By providing the transition portion 220, the length of the joystick 200 can be flexibly controlled so that the position of the handheld portion 210 is close to the driver's hand. Optionally, the transition portion 220 can be designed as a telescopic structure, so that the length of the transition portion 220 can be set according to personal preference to control the height of the handheld portion 210, which is conducive to increasing comfort and maneuverability. The connecting portion 230 is used to realize the rotation connection between the joystick 220 and the second housing 120. In order to improve the rotation convenience, as Figure 5 and Figure 6 As shown, the shape of the connection part 230 can be, for example, cylindrical. Optionally, a dust cover can be provided on the outer surface of the connection part 230 and the second housing 120 to achieve dustproof, waterproof and sealing effects.

[0057] In this embodiment, by respectively providing the third matching portion 122 and the fourth matching portion 231 on the second housing 120 and the connecting portion 230, the joystick 200 can be rotated relative to the base 100 with the second direction Y as the axis. The third matching portion 122 can be, for example, a pin hole provided on the outer wall of the second housing 120, and the fourth matching portion 231 can be, for example, a pin column provided on the outer wall of the connecting portion 230, and the pin column can rotate in the pin hole. Of course, the third matching portion 122 can also be a pin column, and the fourth matching portion 231 can be a pin hole; or the third matching portion 122 and the fourth matching portion 231 can also be other structures, which are not limited in the present application, as long as the joystick 200 can be rotated relative to the base 100 with the second direction Y as the axis.

[0058] In the above embodiment, the second housing 120 can rotate relative to the first housing 110 with the first direction X as the axis, and the joystick 200 can rotate relative to the second housing 120 with the second direction Y as the axis, so that the joystick 200 can rotate in two directions. In other embodiments, the second housing 120 can rotate relative to the first housing 110 with the second direction Y as the axis, and the joystick 200 can rotate relative to the second housing 120 with the first direction X as the axis, so that the joystick 200 can also rotate in two directions, and the present application does not limit this.

[0059] In some embodiments, Figure 3 and Figure 4 As shown, the operating assembly 10 further includes a first elastic member 300 and a second elastic member 400. The first elastic member 300 is disposed between the first housing 110 and the second housing 120. Figure 5 and Figure 6 As shown, the second elastic member 400 is disposed between the joystick 200 and the second housing 120 , and the first elastic member 300 and the second elastic member 400 are used to restore the joystick 200 to an initial position.

[0060] This embodiment is described by taking the example that the second housing 120 can rotate relative to the first housing 110 with the first direction X as the axis and the joystick 200 can rotate relative to the second housing 120 with the second direction Y as the axis.

[0061] By setting the first elastic member 300 between the first shell 110 and the second shell 120, a person needs to apply a certain driving force to rotate the second shell 120 relative to the first shell 110 with the first direction X as the axis; after the driving force of the joystick 200 is cancelled, the first elastic member 300 can restore the relative position of the second shell 120 and the first shell 110 to the initial position. Based on the same principle, by setting the second elastic member 400 between the joystick 200 and the second shell 120, a person needs to apply a certain driving force to rotate the joystick 200 relative to the second shell 120 with the second direction Y as the axis; after the driving force of the joystick 200 is cancelled, the second elastic member 400 can restore the relative position of the joystick 200 and the second shell 120 to the initial position. Thus, the first elastic member 300 and the second elastic member 400 can make the joystick 200 automatically return to the initial position in the first direction X and the second direction Y, which is beneficial to improving the convenience of operating the joystick 200. At the same time, it can also prevent the joystick 200 from being in a driving state without external force, reduce the possibility of misoperation, and improve driving safety.

[0062] In a specific embodiment, Figure 5 and Figure 7 As shown, the fourth matching portion 231 is a first protrusion 2311 formed on the two side walls of the connecting portion 230 along the second direction Y, and the third matching portion 122 is a guide hole 1221 or a guide groove (not shown) formed on the two side walls of the second housing 120 along the second direction Y, the guide hole 1221 or the guide groove extends along the first direction X, and the first protrusion 2311 is also slidably disposed in the guide hole 1221 or the guide groove. In this embodiment, the fourth matching portion 231 is the first protrusion 2311, the third matching portion 122 is the guide groove or the guide hole 1221, and the first protrusion 2311 is also slidably disposed in the guide groove or the guide hole 1221. In this way, when the operating lever 200 rotates with the second direction Y as the axis, the connecting portion 230 of the operating lever 200 will also be displaced along the first direction X relative to the second housing 120. In this way, the activity trajectory of the joystick 200 in the front-rear direction (first direction X) is more consistent with the driver's force state, which is conducive to improving the operating comfort of the joystick 200. Optionally, the guide hole 1221 or the guide groove can be an inverted arc shape, an inverted parabola shape, etc., which can be flexibly set according to actual conditions.

[0063] Furthermore, if Figure 5 and Figure 7 As shown, the second housing 120 is provided with a second protrusion 123 on the inner side wall, one end of the second elastic member 400 is connected to the first protrusion 2311 of the connecting portion 230, and the other end is connected to the second protrusion 123. In this way, the joystick 200 can be automatically returned in the first direction X.

[0064] Of course, in addition to the above embodiments and the methods shown in the accompanying drawings, the first elastic member 300 and the second elastic member 400 can also have other structures and settings, such as torsion springs, etc. The present application does not impose any restrictions on this, as long as it can realize the automatic return of the joystick 200 in the first direction X and the second direction Y.

[0065] In some embodiments, the operating assembly 10 further includes a power-assisting motor (not shown), which is connected to the joystick 200 and is also electrically connected to the controller 2. When the joystick 200 rotates with the first direction X as the axis to control the steering of the vehicle, the controller 2 sends a power-assisting torque for driving the joystick 200 to rotate to the power-assisting motor, thereby providing power assistance for the steering of the joystick 200, which is beneficial to improving the handling stability and comfort during driving.

[0066] In a second aspect, the present application provides a wire control system 1 for a vehicle. Figure 2 As shown, the wire control system 1 includes a brake actuator 3, a drive actuator 4, a steering actuator 5, a controller 2, and the vehicle operating component 10 as described in the first aspect, and the controller 2 is electrically connected to the brake actuator 3, the drive actuator 4, the steering actuator 5, and the operating component 10. In this way, various signals sent by the operating component 10, such as a rotation angle signal, a torque signal, etc., can be transmitted to the controller 2, and the controller 2 then controls the brake actuator 3 to brake the vehicle, controls the drive actuator 4 to drive the vehicle, and controls the steering actuator 5 to steer the vehicle.

[0067] The wire control system 1 of the present application uses the operating component 10 described in the first aspect to replace the functions of the steering wheel, accelerator pedal and brake pedal. In this way, on the first hand, the driving seat in the car does not need to be provided with structures such as a steering wheel, accelerator pedal and brake pedal, so that the space in the car can be saved, and it is convenient to reserve the layout space of other components and the activity space of personnel, which is conducive to improving the driving comfort of personnel and the convenience of the cockpit layout. On the second hand, compared with structures such as a steering wheel, accelerator pedal and brake pedal, the base 100 and the joystick 200 are lighter in weight, more integrated, and easy to maintain, which is also conducive to improving the lightweight and reliability of the vehicle. On the third hand, personnel can control the driving form of the vehicle with one hand, thereby providing a relatively friendly control solution for special groups of people.

[0068] In a third aspect, the present application proposes a vehicle, including the wire control system described in the second aspect. This is conducive to improving the driving comfort of personnel and the convenience of the cockpit layout, as well as improving the lightweight and reliability of the vehicle. In addition, it can also provide a relatively friendly control solution for special groups of people.

[0069] The above contents are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
