Abstract

The invention discloses a redundant braking system and a vehicle, and relates to the technical field of vehicle engineering. The redundant braking system comprises a main voltage buildup module, a brake actuator, a main brake controller and a redundant brake controller. The main voltage buildup module comprises a driving motor and a hydraulic cylinder connected with the driving motor, and the driving motor is provided with a plurality of first winding coils; the brake actuator comprises an electromagnetic valve for opening and closing the hydraulic flow channel, and the electromagnetic valve comprises a plurality of second winding coils; the main brake controller is in control connection with the at least one first winding coil and the at least one second winding coil; and the redundant brake controller is in control connection with at least one other first winding coil and at least one other second winding coil, and the redundant brake controller and the main brake controller monitor each other. The redundant braking system has the advantages of being low in cost and high in integration degree on the premise that the braking redundancy safety is met.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a redundant braking system and a vehicle. Background technique [0002] With the advent of automobile intelligence, the application of autonomous driving technology is getting deeper and deeper, and there are more and more vehicles with autonomous driving above L3 level. It is more and more important for the braking system to ensure the safety of vehicles. The promulgation of the autonomous driving regulation SAE J3016_201806 puts forward new requirements for the braking system of L3 and above, that is, the braking system of L3 and above is required to backup a redundant braking unit in addition to its own main braking unit. In case of brake failure of the main brake unit, the redundant brake unit is required to be able to brake normally, so as to execute the instructions of the automatic driving system, so as to meet the brake redundancy safety. [0003] The existin...
