Servo adjustable wire brake system, control method, storage medium and terminal

Abstract

The invention discloses a servo-adjustable wire-controlled brake system, a control method, a storage medium and a terminal. The system comprises a pedal simulator electronic control unit, a simulator pressure regulating chamber, a simulator master cylinder, a servo motor and a transmission part; The simulator pressure regulating chamber is connected with the simulator master cylinder, and the simulator master cylinder is connected with the brake master cylinder; the pedal simulator electronic control unit is electrically connected with the servo motor, and the pedal simulator electronic control unit is set to receive the brake master cylinder. The sent braking stroke signal, according to the braking stroke signal and the preset pedal stroke-pedal force characteristic table, adjust the rotation angle of the servo motor in real time; the transmission part is connected with the servo motor, and the transmission part is used to rotate the output shaft of the servo motor Translates to the movement of the piston of the simulator surge chamber. In the present invention, the pedal feeling is arbitrarily set by the control unit, which solves the problem that the feedback of the pedal feeling is relatively simple, and realizes that the pedal feeling can be adjusted according to the vehicle model or driving style.

Description

technical field [0001] The invention relates to the technical field of vehicle brake-by-wire, in particular to a servo-adjustable brake-by-wire system, a control method, a storage medium and a terminal. Background technique [0002] see figure 1 , In the traditional brake-by-wire system, the driver inputs the braking request by stepping on the brake pedal. Close the valve) and power on, so that the brake master cylinder circuit 1 is connected with the pedal simulator master cylinder, the brake master cylinder oil smoothly enters the pedal simulator with the pedal force input, and the pedal simulator master cylinder enters the pedal simulator with the oil. The first section of spring and the second section of spring are contacted successively, and the pedal feeling is simulated by the springs at both ends and fed back to the driver. The brake-by-wire system mainly includes pedal simulator solenoid valve, pedal simulator master cylinder and spring and other components. The s...

Problems solved by technology

[0003] The purpose of the present invention is to provide a servo adjustable brake-by-wire system and an electric vehicle. The pedal feel can be set arbitrarily through the electronic control unit of the pedal simulator, and the simulation of the pedal feel of the existing electric vehicle mainly depends on the pedal simulator master cylinder and its The spring provides feedback, and the integration level is low, which leads to the problem that the quality of the foot feel simulation is not high, and the simulation feeling cannot be adjusted actively
