Document Type and Number:
WIPO Patent Application WO/2021/056842
Kind Code:
A1
Abstract:
Provided are a braking relief control method and device; a braking relief instruction is obtained, driving parameters of a vehicle are obtained, and it is determined whether the driving parameters satisfy at least one preset requirement; if so, then, according to the brake relief instruction, it is determined that the current braking relief mode is slow-relief braking mode; according to the slow-relief braking mode, a brake cylinder pressure value of a brake mechanism of the vehicle is controlled to reduce according to a preset first reduction mode, the reduction rate of the first reduction mode being lower than a preset rate; if the vehicle is in specific driving conditions, then the braking relief process of the vehicle is controlled according to the slow-relief braking mode, allowing the vehicle to have sufficient time to build up enough traction to overcome the starting resistance during the braking relief process, preventing the risk of slipping and reducing the impact of braking.
