Document Type and Number:
WIPO Patent Application WO/2022/022254
Kind Code:
A1
Abstract:
A brake redundancy method and system, and a self-driving vehicle, comprising: when a current working condition of the vehicle satisfies a preset braking condition, a self-driving main controller sends, successively through a CAN bus, a gateway and a chassis main CAN bus, a first braking request to a main brake controller and a backup brake controller of the vehicle; when receiving the first braking request, the main brake controller brakes the vehicle according to the first braking request; and when receiving the first braking request, the backup brake controller determines a first braking instruction corresponding to the first braking request and executes the first braking instruction if the main brake controller is determined to be ineffective. According to the control method, the probability of braking delays can be reduced, vehicle safety is thus improved, and the incidence of traffic accidents of the self-driving vehicle is reduced.
