車両制動方法及び装置

Abstract

This application provides a vehicle braking method and apparatus. In the technical solution provided in this application, the hydraulic efficiency gear in the vehicle is controlled to provide a first target hydraulic pressure to the front axle and the rear axle, and the motor device in the vehicle is controlled to provide a first electric braking force to the front axle and a second electric braking force to the rear axle. The sum of the first hydraulic braking force generated by the first target hydraulic pressure for the front axle, the second hydraulic braking force generated by the first target hydraulic pressure for the rear axle, the first electric braking force, and the second electric braking force is equal to the total braking force required to brake the vehicle. The ratio of the first sum of the first hydraulic braking force and the first electric braking force to the second sum of the second hydraulic braking force and the second electric braking force is equal to the ratio of the first vertical load of the front axle of the vehicle to the second vertical load of the rear axle of the vehicle. The technical solution provided in this application helps to improve the stability of the vehicle during braking.
