Abstract

The present invention provides a brake control method, device and system, wherein the method is applied to a decoupled electronic brake booster of a vehicle, the vehicle also includes an electronic stability control system, and the method includes: monitoring the vehicle The displacement of the brake pedal; according to the displacement, determine the target braking force value; when it is determined that the actuator of the electronic brake booster fails, send the first braking signal to the electronic stability control A system for the electronic stability control system to respond to a braking request and brake the vehicle according to the target braking force value; wherein the first braking signal includes the braking request and the target braking force Momentum value. The invention solves the problem that when the executive mechanism of the existing decoupling electronic brake booster fails, the braking distance and the braking response time are long due to the existence of the decoupling gap, which affects the driving safety of the vehicle.

Description

technical field [0001] The present invention relates to the technical field of automobiles, and in particular, to a braking control method, device and system. Background technique [0002] At present, as a new type of electronic brake booster structure, the decoupled electronic brake booster can realize energy recovery without relying on the electronic stability control unit (ESC) of the vehicle because of the decoupling gap. Braking, so it is more and more widely used in electric vehicles, hybrid vehicles and fuel vehicles. [0003] The decoupled electronic brake booster uses the pedal displacement sensor (Pedal Travel Sensor, PTS) to monitor the position of the brake pedal, and then judges the driver's intention, and then drives the mechanical actuator through the motor to generate the brake fluid pressure to achieve The effect of brake assist. However, when the electronic brake booster fails due to mechanical failure, aging or Rotaryposition sensor (RPS) failure, etc., ...
