The invention discloses an integrated braking electric control system and a liquid replenishment method, belonging to the technical field of electric control systems. A hydraulic channel is set between the liquid storage tank and the servo cylinder, and a check valve is installed on the hydraulic channel; the integrated brake electronic control system also includes an anti-lock brake module, a regenerative brake module, a brake fluid return control module and a valve system control module , the brake fluid return control module receives the anti-lock function start signal sent by the anti-lock brake module, the servo cylinder pressure signal and the regenerative brake function start signal sent by the regenerative brake module, and the brake fluid return control module sends four wheels The side booster valve opening signal is sent to the valve system control module, and the valve system control module sends the pulse width modulation signal to the valve system actuator, and the motor angle signal is sent from the motor angle sensor built in the permanent magnet synchronous motor to the brake fluid return control module middle. The invention can greatly reduce the switching times of the electromagnetic valve, and make the fluid replenishment volume more sufficient and the pedal stroke closer to the target value.
Description
technical field [0001] The invention relates to the technical field of electric control systems, in particular to an integrated brake electric control system and a fluid replenishment method. Background technique [0002] With the rapid development of automobile intelligence and networking, more and more vehicles are equipped with integrated brake electronic control systems. When the anti-lock braking system and regenerative braking system work, the integrated brake electronic control system will control the motor and the corresponding valve system to decompress the brake fluid at the brake caliper end. The electronic control system needs to immediately control the motor and the corresponding valve system to replenish the brake caliper end to counteract the impact of decompression on pedal feel. There are two problems in the liquid replenishment method adopted in the prior art: one is that the electromagnetic valve must be frequently opened and closed during the liquid repl...
