Problems solved by technology

[0006] In view of this, the present invention aims to propose a braking control method, device and system to solve the problem of the braking distance and the braking distance easily caused by the existence of the decoupling gap when the executive mechanism of the existing decoupling electronic brake booster fails. The brake response time is long, which affects the driving safety of the vehicle

Abstract

The invention provides a brake control method, device and system, the method is applied to a decoupling type electronic brake booster of a vehicle, the vehicle further comprises an electronic stability control system, and the method comprises the steps of monitoring the displacement of a brake pedal of the vehicle; determining a target braking force value according to the displacement; under the condition that it is determined that an executing mechanism of the electronic brake booster fails, sending a first brake signal is sent to the electronic stability control system, so that the electronic stability control system responds to a brake request and brakes the vehicle according to the target brake force value, wherein the first braking signal comprises the braking request and the target braking force value. The decoupling type electronic brake booster solves the problems that when an executing mechanism of an existing decoupling type electronic brake booster fails, due to the decoupling gap, the brake distance and the brake response time are long, and the driving safety of a vehicle is affected.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a braking control method, device and system. Background technique [0002] At present, the decoupled electronic brake booster is a new type of electronic brake booster structure. Because of the decoupling gap, it can achieve energy recovery without relying on the vehicle's Electronic Stability Control (ESC) Braking, so it is more and more widely used in electric vehicles, hybrid vehicles and fuel vehicles. [0003] The decoupled electronic brake booster uses a pedal travel sensor (Pedal Travel Sensor, PTS) to monitor the position of the brake pedal to judge the driver's intention, and then the motor drives the mechanical actuator to generate brake fluid pressure to achieve The effect of brake boosting. However, when the electronic brake booster fails due to mechanical failure, aging or rotation angle sensor (Rotary position sensor, RPS) failure and other reasons, the electr...
