Problems solved by technology

However, the potential safety hazard is that the brake signal source of the vehicle controller is only the electronically controlled braking system. If the electronically controlled braking system has a communication failure, the electronically controlled braking system cannot correctly transmit the braking signal to the vehicle. The controller, in this way, will cause the vehicle controller to fail to issue braking commands in time

Abstract

The invention relates to a brake control method and system, electronic equipment and a storage medium. The method comprises the steps that a vehicle control unit receives a first brake signal sent byan advanced driving assistance system, wherein the first brake signal includes a first brake force degree value, and the first brake force degree value is determined by the advanced driving assistancesystem based on first collected data; the vehicle control unit also receives a second brake signal sent by an electronic control brake system, wherein the second brake signal includes a second brakeforce degree value, and the second brake force degree value is determined by the electronic control brake system based on second collected data; and the vehicle control unit determines a target brakeforce degree value according to the first brake force degree value and the second brake force degree value, and sends an execution command to a motor controller according to the target brake force degree value. A braking signal source of the advanced driving assistance system is increased, and double-source control is adopted for the vehicle control unit so that running safety of the vehicle can be improved.

Description

technical field [0001] The present application relates to the technical field of vehicle safety, in particular to a braking control method, system, electronic equipment and storage medium. Background technique [0002] The electronically controlled braking system (Electric Braking System, EBS) is based on the anti-lock braking system (Antilock Braking System, ABS), and uses electronic control to replace the traditional mechanical transmission to control the braking system. The moving distance can achieve good braking effect and increase the safety of automobile braking. [0003] When the car is braking, the electronic control braking system calculates the required braking force through the data collected by the load and ground adhesion through various sensors, and forms a braking signal and sends it to the vehicle control unit (VCU) , and then sent to the motor controller by the vehicle controller, and the motor controller outputs different negative torques according to dif...
