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 present application relates to a braking control method, system, electronic device and storage medium. The method includes: a vehicle controller receives a first braking signal sent by an advanced driving assistance system; the first braking signal includes a first braking force level The first braking force level value is determined by the advanced driving assistance system based on the first collected data; the vehicle controller also receives the second braking signal sent by the electronically controlled braking system; the second braking signal includes the second braking force degree value; the second braking force degree value is determined by the electronically controlled braking system based on the second collected data; the vehicle controller determines the target braking force degree value from the first braking force degree value and the second braking force degree value, and Send an execution command to the motor controller according to the target braking force level value. The application increases the braking signal source of the advanced driving assistance system, and adopts dual-source control for the vehicle controller, so that the safety of vehicle operation 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...
