Description

Technical Field

[0001] This utility model relates to the field of vehicles, specifically to a pedal feel simulator based on an electromagnet and its vehicle. Background Technology

[0002] In traditional braking systems, the brake pedal and brake are connected hydraulically or mechanically to transmit braking feedback force to the driver. However, the mainstream electro-hydraulic brake-by-wire system decouples the pedal and brake, eliminating the force transmission mechanism between them, so the driver does not feel braking force feedback. To solve this problem, pedal simulators are commonly used to simulate traditional pedal feedback force, allowing the driver to experience the "braking feel."

[0003] Given that the brake pedal characteristic curve exhibits non-linear features, and springs, as typical elastic elements, can only exhibit linear mechanical properties, the "braking experience" obtained by simply relying on springs of different stiffnesses to simulate the braking feel differs significantly from the ideal state, making it difficult to accurately reproduce the real and complex brake pedal feel. Summary of the Invention

[0004] The purpose of this invention is to provide an electromagnet-based pedal feel simulator and its vehicle, in order to solve the problem in the prior art that it is difficult to accurately reproduce the real and complex braking feel due to the use of springs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An electromagnet-based pedal feel simulator includes: a simulator piston and a simulator cylinder, the simulator piston being movably mounted in the simulator cylinder and capable of moving axially within the simulator cylinder; an elastic element disposed within the simulator cylinder and supporting the simulator piston to prevent the simulator piston from moving in a direction that compresses the elastic element; an armature and an electromagnet, the armature being fixed to the simulator piston and the electromagnet being fixed to the simulator cylinder, the electromagnet being correspondingly disposed with respect to the armature so that the electromagnet can apply a magnetic force to the armature, and the electromagnet being configured to be able to change the magnitude of the magnetic force.

[0006] Based on the above technical means, by introducing the interaction between the electromagnet and the armature, and combining it with the linear reaction force of the elastic element, a nonlinear force can be synthesized to prevent the simulator piston from moving towards the elastic element, effectively overcoming the limitation that only linear feedback can be provided when relying solely on the spring; the magnetic force of the electromagnet is adjustable, so that the braking feel of the pedal can be adjusted in real time and dynamically as needed, thereby more accurately reproducing the real and complex braking feel.

[0007] In this invention, magnetic force is combined with mechanical elasticity, and the electromagnet is configured to change the magnitude of the magnetic force. By adjusting the magnetic force of the electromagnet, the additional force applied to the simulator piston can be adjusted, making it closer to the feel of a traditional hydraulic braking system.

[0008] Furthermore, it also includes a pedal, a hydraulic cylinder, a push rod, and a first oil pipe. The hydraulic cylinder is connected to the simulator cylinder body through the first oil pipe, and the push rod is connected between the pedal and the hydraulic cylinder.

[0009] According to the above technical means, the push rod is connected between the pedal and the hydraulic cylinder. When the pedal moves, it can push the push rod, thereby driving the hydraulic cylinder. Since the first oil pipe is connected to the simulator cylinder, the hydraulic cylinder can squeeze the liquid inside when it is driven. The liquid flows through the first oil pipe to the simulator cylinder and can squeeze the simulator piston. When the simulator piston is squeezed, the elastic element can rebound the pressure of the simulator piston. At the same time, the magnetic force of the electromagnet increases, which increases the magnetic force between the electromagnet and the armature to prevent the simulator piston from squeezing the elastic element. At this time, the liquid in the simulator cylinder can reach the hydraulic cylinder through the first oil pipe to drive the hydraulic cylinder in the opposite direction to push the push rod, so that the push rod provides resistance to the pedal.

[0010] Furthermore, it also includes a displacement sensor mounted on the push rod, the displacement sensor being used to acquire displacement data of the pedal; the electromagnet is configured to change the magnitude of its magnetic force according to the displacement data.

[0011] Based on the above technical means, by installing a displacement sensor on the push rod and using the displacement sensor to acquire the displacement data of the pedal, the displacement sensor can monitor the travel and speed of the driver pressing the pedal in real time and accurately. The electromagnet is configured to change the magnitude of the magnetic force according to the displacement data. The change of magnetic force can closely follow the change of pedal travel, making the force feedback smoother and avoiding the lag or abrupt feeling that may exist in traditional mechanical mechanisms, thus improving the pedal feel experience.

[0012] Furthermore, it also includes an electronic control unit and an electromagnet controller; the electronic control unit is communicatively connected to the displacement sensor to acquire the displacement data from the displacement sensor; the electromagnet controller is communicatively connected to both the electronic control unit and the electromagnet, and the electromagnet controller is configured to adjust the magnetic force of the electromagnet according to the displacement data.

[0013] Based on the aforementioned technical means, the electronic control unit is communicatively connected to the displacement sensor and the electromagnet controller. The electronic control unit can acquire displacement data and send signals to the electromagnet controller. Since the electromagnet and the electromagnet controller are communicatively connected, the electromagnet controller can adjust the magnetic force of the electromagnet according to the generated signal, which can accurately simulate the nonlinear pedal feel that meets actual needs, providing the driver with a more realistic, comfortable, and adaptable braking feedback experience for various scenarios. That is, the simulator can adjust the feedback characteristics in real time according to different working conditions; and by adjusting the magnetic force of the electromagnet through the displacement sensor, electronic control unit, electromagnet controller, and electromagnet, it is ensured that the driver can promptly and accurately perceive the feedback information of the braking system the moment the brake pedal is pressed, thus improving the response speed.

[0014] Furthermore, it also includes a power supply, which is electrically connected to the electromagnet controller and the electromagnet.

[0015] According to the above technical means, a power supply is also included. The power supply is electrically connected to the electromagnet controller and the electromagnet. Even if there are some abnormalities in the main power supply of the vehicle, it can ensure that the pedal simulator can work briefly when needed, thereby improving the functional safety level of the system.

[0016] Furthermore, the hydraulic cylinder includes a hydraulic cylinder body, a first hydraulic piston, and a second hydraulic piston. The first and second hydraulic pistons are installed in the hydraulic cylinder body. A first spring is provided between the first and second hydraulic pistons. A second spring is provided between the first hydraulic piston and the hydraulic cylinder body. The push rod extends into the hydraulic cylinder body and connects to the second hydraulic piston.

[0017] According to the above technical means, when the pedal is pressed, the push rod first pushes the second hydraulic piston, compressing the first spring. At this time, the stiffness of the first spring is small, and only the first spring provides resistance to the pedal, so that the driver can initially feel a certain resistance when pressing the pedal. When the first spring is compressed to a certain extent, the second hydraulic piston contacts the first hydraulic piston and begins to move together. At this time, the first spring and the second spring need to be compressed at the same time, and the liquid in the hydraulic cylinder is squeezed into the simulator cylinder. The first spring between the first hydraulic piston and the second hydraulic piston plays a buffering and connecting role, which can make the force transmission smoother, absorb possible impacts and vibrations, and make the pedal pressing process more delicate and without any jerking.

[0018] Furthermore, it also includes an oil reservoir and a second oil pipe, the oil reservoir being connected to the hydraulic cylinder via the second oil pipe.

[0019] Based on the aforementioned technical means, during system operation, due to temperature changes and minor oil volume variations that may occur due to piston movement, the oil reservoir can supply oil into the hydraulic cylinder through the second oil pipe to compensate for these oil volume changes. This prevents cavitation or overpressure within the system, ensuring that the transmission of hydraulic force remains consistently smooth, continuous, and precise. This is crucial for maintaining the consistency and realism of the pedal feel.

[0020] Furthermore, a limiting protrusion is formed at one end of the simulator piston near the elastic element. The limiting protrusion can engage with the elastic element to prevent misalignment during the movement of the simulator piston.

[0021] According to the above technical means, a limiting protrusion is formed at one end of the simulator piston near the elastic element, and the limiting protrusion can be engaged with the elastic element. On the one hand, it can prevent the simulator piston from being misaligned during the process of squeezing the elastic element; on the other hand, it can provide a stable force point for the simulator piston to squeeze the elastic element, so as to ensure the stability of the simulator.

[0022] Furthermore, the elastic element is a simulator spring, and the limiting protrusion is engaged with the simulator spring.

[0023] Furthermore, a vehicle is also provided, which further includes the aforementioned pedal feel simulator, the pedal feel simulator being installed on the vehicle.

[0024] The beneficial effects of this utility model are: 1. By introducing the interaction between the electromagnet and the armature, and combining it with the linear reaction force of the elastic element, a nonlinear force can be synthesized to prevent the simulator piston from moving towards the elastic element, effectively overcoming the limitation of only providing linear feedback when relying solely on the spring; the magnetic force of the electromagnet is adjustable, so that the braking feel of the pedal can be adjusted dynamically in real time as needed, thereby more accurately reproducing the real and complex braking feel.

[0025] 2. In this utility model, magnetic force is combined with mechanical elastic force, and the electromagnet is configured to change the magnitude of the magnetic force. By adjusting the magnetic force of the electromagnet, the additional force applied to the simulator piston can be adjusted, making it closer to the feel of a traditional hydraulic braking system.

Detailed Implementation

[0028] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0029] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0030] like Figure 1 As shown, this embodiment proposes a pedal feel simulator based on an electromagnet, including: a simulator piston 1 and a simulator cylinder 2, the simulator piston 1 is movably installed in the simulator cylinder 2, and the simulator piston 1 can move axially within the simulator cylinder 2; an elastic element 3, the elastic element 3 is disposed within the simulator cylinder 2, and supports the simulator piston 1 to prevent the simulator piston 1 from moving in the direction of squeezing the elastic element 3; an armature 4 and an electromagnet 5, the armature 4 is fixed on the simulator piston 1, and the electromagnet 5 is fixed outside the simulator cylinder 2, the electromagnet 5 is correspondingly arranged with the armature 4 so that the electromagnet 5 can apply magnetic force to the armature 4, and the electromagnet 5 is configured to be able to change the magnitude of the magnetic force.

[0031] like Figure 2 and Figure 3 As shown, the process in this embodiment is as follows: when the simulator piston 1 moves in the direction of squeezing the elastic member 3, the elastic member 3 will generate elastic force to resist the simulator piston 1 from moving in the direction of squeezing the elastic member 3. At the same time, the electromagnet 5 and the armature 4 will attract each other due to magnetic force to resist the simulator piston 1 from moving in the direction of squeezing the elastic member 3.

[0032] By introducing the interaction between electromagnet 5 and armature 4, and combining it with the linear reaction force of elastic element 3, a nonlinear force can be synthesized to prevent simulator piston 1 from moving towards elastic element 3, effectively overcoming the limitation of only providing linear feedback when relying solely on springs; the magnetic force of electromagnet 5 is adjustable, allowing the braking feel of the pedal to be adjusted dynamically and in real time as needed, thereby more accurately reproducing the realistic and complex braking feel; by combining magnetic force with mechanical elasticity, and by configuring electromagnet 5 to change the magnitude of the magnetic force, the additional force applied to simulator piston 1 can be adjusted by adjusting the magnetic force of electromagnet 5, making it closer to the feel of traditional hydraulic braking systems.

[0033] like Figure 1 As shown, in this preferred embodiment, the simulator piston 1 is tightly fitted to the inner wall of the simulator cylinder 2.

[0034] like Figure 1 As shown, in this embodiment, the system also includes a pedal 6, a hydraulic cylinder 7, a push rod 8, and a first oil pipe 9-1. The hydraulic cylinder 7 is connected to the simulator cylinder body 2 through the first oil pipe 9-1, and the push rod 8 is connected between the pedal 6 and the hydraulic cylinder 7.

[0035] Push rod 8 is connected between pedal 6 and hydraulic cylinder 7. When pedal 6 moves, it can push push rod 8, thereby driving hydraulic cylinder 7. Since the first oil pipe 9-1 is connected to simulator cylinder 2, when hydraulic cylinder 7 is driven, it can squeeze the liquid inside hydraulic cylinder 7. The liquid flows through the first oil pipe 9-1 to simulator cylinder 2, which can squeeze simulator piston 1. When simulator piston 1 is squeezed, elastic element 3 can rebound the pressure of simulator piston 1. At the same time, the magnetic force of electromagnet 5 increases, which makes the magnetic force between electromagnet 5 and armature 4 larger, so as to prevent simulator piston 1 from squeezing elastic element 3. At this time, the liquid inside simulator cylinder 2 can reach hydraulic cylinder 7 through the first oil pipe 9-1 to drive hydraulic cylinder 7 in the opposite direction to push push rod 8, so that push rod 8 provides resistance to pedal 6.

[0036] like Figure 1 As shown, in this embodiment, a displacement sensor 10 is also included. The displacement sensor 10 is mounted on the push rod 8 and is used to acquire displacement data of the pedal 6. The electromagnet 5 is configured to change the magnitude of the magnetic force according to the displacement data.

[0037] By mounting the displacement sensor 10 on the push rod 8, and using the displacement sensor 10 to acquire the displacement data of the pedal 6, the displacement sensor 10 can monitor the stroke and speed of the driver pressing the pedal 6 in real time and accurately. The electromagnet 5 is configured to change the magnitude of the magnetic force according to the displacement data. The change of magnetic force can closely follow the change of the pedal 6 stroke, making the force feedback smoother and avoiding the lag or abrupt feeling that may exist in traditional mechanical mechanisms, thus improving the pedal 6 feel.

[0038] like Figure 1 As shown, this embodiment also includes an electronic control unit 11 and an electromagnet controller 12; the electronic control unit 11 is communicatively connected to the displacement sensor 10 to acquire displacement data from the displacement sensor 10; the electromagnet controller 12 is communicatively connected to the electronic control unit 11 and the electromagnet 5 respectively, and the electromagnet controller 12 is configured to adjust the magnetic force of the electromagnet 5 according to the displacement data.

[0039] The electronic control unit 11 is communicatively connected to the displacement sensor 10 and the electromagnet controller 12. The electronic control unit 11 can acquire displacement data and send signals to the electromagnet controller 12. Since the electromagnet 5 is communicatively connected to the electromagnet controller 12, the electromagnet controller 12 can adjust the magnetic force of the electromagnet 5 according to the signal, which can accurately simulate the nonlinear pedal 6 feel that meets actual needs, providing the driver with a more realistic, comfortable, and adaptable braking feedback experience in various scenarios. That is, the simulator can adjust the feedback characteristics in real time according to different working conditions. Furthermore, by adjusting the magnetic force of the electromagnet 5 through the displacement sensor 10, the electronic control unit 11, the electromagnet controller 12, and the electromagnet 5, it is ensured that the driver can promptly and accurately perceive the feedback information of the braking system the moment the brake pedal 6 is pressed, thus improving the response speed.

[0040] like Figure 1 As shown, this embodiment also includes a power supply 13, which is electrically connected to the electromagnet controller 12 and the electromagnet 5. Even if the vehicle's main power supply experiences some abnormalities, it ensures that the pedal 6 simulator can operate briefly when needed, thus improving the system's functional safety level.

[0041] like Figure 1 As shown, in this embodiment, the hydraulic cylinder 7 includes a hydraulic cylinder body 7-1, a first hydraulic piston 7-1, and a second hydraulic piston 7-2. The first hydraulic piston 7-1 and the second hydraulic piston 7-2 are installed inside the hydraulic cylinder body 7-1. A first spring 7-4 is provided between the first hydraulic piston 7-1 and the second hydraulic piston 7-2. A second spring 7-5 is provided between the first hydraulic piston 7-1 and the hydraulic cylinder body 7-1. The push rod 8 extends into the hydraulic cylinder body 7-1 and connects to the second hydraulic piston 7-2.

[0042] like Figure 1As shown, when pedal 6 is pressed, push rod 8 first pushes the second hydraulic piston 7-2, compressing the first spring 7-4. At this time, the first spring 7-4 has a small stiffness, and only the first spring 7-4 provides resistance to pedal 6, so that the driver can initially feel a certain resistance when pressing pedal 6. When the first spring 7-4 is compressed to a certain extent, the second hydraulic piston 7-2 contacts the first hydraulic piston 7-1 and begins to move together. At this time, the first spring 7-4 and the second spring 7-5 need to be compressed at the same time, and the liquid in the hydraulic cylinder 7-1 is squeezed into the simulator cylinder 2. The first spring 7-4 between the first hydraulic piston 7-1 and the second hydraulic piston 7-2 plays a buffering and connecting role, which can make the force transmission smoother, absorb possible impacts and vibrations, and make the pedal 6 pressing process more delicate and without jerking.

[0043] like Figure 1 As shown, in this embodiment, an oil reservoir 14 and a second oil pipe 9-2 are also included. The oil reservoir 14 is connected to the hydraulic cylinder 7 through the second oil pipe 9-2.

[0044] During system operation, due to temperature changes and minor oil volume variations that may occur due to piston movement, the oil reservoir 14 can supply oil (the liquid in the oil reservoir 14) into the hydraulic cylinder 7 through the second oil pipe 9-2 to compensate for oil changes within the hydraulic cylinder 7. This prevents cavitation or overpressure from occurring within the system, ensuring that the transmission of hydraulic force remains smooth, continuous, and precise. This is crucial for maintaining the consistency and realism of the pedal feel.

[0045] like Figures 1-3 As shown, in this embodiment, a limiting protrusion 1-1 is formed at one end of the simulator piston 1 near the elastic member 3. The limiting protrusion 1-1 can be engaged with the elastic member 3 to prevent misalignment during the movement of the simulator piston 1.

[0046] The simulator piston 1 has a limiting protrusion 1-1 at one end near the elastic element 3, and the limiting protrusion 1-1 can be engaged with the elastic element 3. On the one hand, it can prevent the simulator piston 1 from being misaligned during the process of squeezing the elastic element 3; on the other hand, it can provide a stable force point for the simulator piston 1 to squeeze the elastic element 3, so as to ensure the stability of the simulator.

[0047] like Figures 1-3 As shown, in this embodiment, the elastic element 3 is a simulator spring, and the limiting protrusion 1-1 is snapped onto the simulator spring.

[0048] In summary, as Figures 1-3 As shown, the implementation process of this embodiment is as follows: When pedal 6 is pressed, it pushes push rod 8 to move. Push rod 8 pushes the second piston. Since a second spring 7-5 is provided between the second piston and the first hydraulic piston 7-2, and a first spring 7-4 is provided between the first spring 7-4 and the hydraulic cylinder 7-1, it can push the first hydraulic piston 7-2 and compress the volume between the first hydraulic piston 7-2 and the hydraulic cylinder 7-1. The oil in the space between the first hydraulic piston 7-2 and the hydraulic cylinder 7-1 enters the simulator cylinder 2 through the first oil pipe 9-1 to compress the simulator piston 1. The elastic element 3 can apply pressure to the simulator piston 1 to prevent the simulator piston 1 from compressing the elastic element 3. When pedal 6 is pressed, displacement sensor 10 can acquire displacement data of pedal 6 and transmit the displacement data to electronic control unit 11. Electronic control unit 11 sends a signal to electromagnet controller 12 according to the displacement data. Electromagnet controller 12 receives the signal and changes the magnetic force of electromagnet 5 to prevent simulator piston 1 from compressing elastic element 3, thereby preventing oil from entering simulator cylinder 2, so as to apply resistance to pedal 6 to simulate the pedal feel during braking.

[0049] Example 2 This embodiment is similar to Embodiment 1, and the same parts are described in Embodiment 1. The following description only focuses on the improved parts.

[0050] In this embodiment, a vehicle is also provided, including a vehicle body and the aforementioned pedal feel simulator, which is installed on the vehicle.

Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
