Abstract

This application relates to a brake redundancy backup system and a braking method suitable for automatic driving. The data acquisition sensor group is connected with an integrated electronic booster and a brake backup unit, and is used to collect vehicle operating state data; automatic driving assistance subsystem It is connected with the integrated electronic booster and brake backup unit through the vehicle bus, and is used to generate braking commands according to the vehicle operating status data. The braking command is a driving brake command or a parking brake command; the integrated electronic booster and The four wheels are connected and are used to respond to the service brake command and perform service braking; the brake backup unit is connected to the two front wheels and two electronic parking actuators and is used to respond to the parking brake command and perform parking Vehicle braking, and when the integrated electronic booster fails, it responds to the service brake command and performs service braking. The application can solve the problem in the related art that the brake redundancy backup cannot be taken into account, the system complexity can be reduced and the economy can be improved.

Description

technical field [0001] The present application relates to the technical field of automatic driving vehicle braking, in particular to a braking redundancy backup system and a braking method suitable for automatic driving. Background technique [0002] Automated driving technology has been in development for decades. At the beginning of the 21st century, it showed a trend close to practicality. Autonomous driving is to sense the road environment through the on-board sensor system, automatically plan the driving route and control the vehicle to reach the predetermined target. [0003] The realization of automatic driving benefits from the development of brake-by-wire technology. Brake-by-wire has the advantages of fast response and high precision, and gradually replaces traditional vacuum assist in advanced driver assistance systems. However, potential failures and Failure will cause safety hazards to the braking system. Ensuring the safety and reliability of the braking syst...
