Abstract

The invention relates to a brake redundancy backup system suitable for automatic driving, and a brake method. A data acquisition sensor group is connected with an integrated electronic booster and a brake backup unit and is used for acquiring vehicle running state data; the automatic driving auxiliary subsystem is connected with the integrated electronic booster and the brake backup unit through an automobile bus and used for generating a brake instruction according to the vehicle running state data, and the brake instruction is a service brake instruction or a parking brake instruction; the integrated electronic booster is connected with the four wheels and is used for responding to a service braking instruction and carrying out service braking; and the brake backup unit is connected withthe two front wheels and the two electronic parking actuators, and is used for responding to the parking brake instruction, carrying out parking brake, responding to the service brake instruction when the integrated electronic booster breaks down, and carrying out service brake. According to the system, the problem that the brake redundancy backup, the reduction of the complexity of the system and the improvement of the economy cannot be considered in related technologies can be solved.

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...
