In an actual implementation process, when a driver controls a vehicle to park, a controller of an electromechanical brake system detects that the vehicle is stationary, a communication device 500 sends a parking instruction to a control component, after the control component receives the corresponding instruction, for example, the parking instruction, the first caliper motor and the second caliper motor can output corresponding braking force, and respectively transmit the braking force to corresponding calipers through corresponding transmission mechanisms, so that the calipers can execute corresponding clamping actions, the first caliper motor and the second caliper motor are used for respectively driving the first caliper and the second caliper, after the first caliper and the second caliper clamp, a locking mechanism, for example, a first electromagnetic valve and a second electromagnetic valve, push a corresponding electronic valve push rod based on the driving instruction of the control component is used, a locking piece, for example, a pawl is pressed by the electromagnetic valve push rod, and is clamped with a corresponding transmission mechanism, for example, a main shaft of the caliper motor, a ratchet wheel connected with the locking piece is clamped, so that the main shaft of the caliper motor is clamped, when the release instruction is received, the communication device 500 can send the release instruction to the control component, and further control the locking mechanism, for example, the first electromagnetic valve and the second electromagnetic valve are used for reversing the pawl, the reset, the braking force is released under the action of the reset main shaft of the electromagnetic valve.

For example, the first control assembly 300 and the second control assembly 400 may be controllers of an electromechanical brake system, where the electromechanical brake system does not need brake fluid and hydraulic components, and braking torque may be generated by motor-driven actuators installed on four tires, so that devices such as a brake master cylinder and a hydraulic pipeline may be omitted correspondingly, the structure of the brake system is simplified, the arrangement, the assembly and the maintenance are convenient, and more significantly, pollution to the environment is reduced along with the cancellation of the brake fluid.

Alternatively, in one embodiment of the present application, the communication device 500 transmits a parking instruction to any one of the parking chips, and any one of the parking chips receiving the parking instruction serves as a communication chip to transmit the parking instruction to the other parking chips.

Further, according to the embodiment of the application, after any parking chip receives the parking instruction sent by the communication device 500, the parking instruction is forwarded to other parking chips, and the communication device 500 does not need to communicate with a plurality of parking chips at the same time, so that the signal transmission efficiency and the transmission quality can be improved, and the parking brake response efficiency of the vehicle is ensured.

For example, after the first parking chip 301 in the first control assembly 300 receives the parking instruction sent by the communication device 500, the first parking chip 301 may forward the parking instruction to the second parking chip 401 in the second control assembly 400, without the communication device 500 sending the parking instruction to the first parking chip 301 and the second parking chip 401 at the same time.

Optionally, in an embodiment of the present application, the communication device 500 is a vehicle controller.

In the actual execution process, the embodiment of the application CAN use the whole vehicle controller as the communication device 500, and transmit the instruction and the information with the related controlled object through the CAN bus communication interface or directly control the instruction through the I/O interface, so as to realize the communication of the parking instruction in the vehicle.
