The invention discloses a distribution method and device for braking torque of a vehicle and a storage medium, and belongs to the technical field of vehicle control. The method comprises the following steps: determining a target brake torque according to a pedal travel of a brake pedal of a vehicle; when the vehicle meets the electro-hydraulic braking condition, torque is distributed to a motor and a hydraulic braking system according to the target braking torque to obtain respective distributed torque, the vehicle is braked according to the respective distributed torque to obtain the actual braking torque of the vehicle, and the vehicle is braked according to the target braking torque and the actual braking torque. And the actual hydraulic braking torque of the hydraulic braking system is adjusted so that the actual braking torque can be equal to the target braking torque. When the driving motor and the hydraulic braking system jointly provide the braking force of the vehicle, the flexibility of the braking relation between electric braking and hydraulic braking is guaranteed, the electric braking force corresponding to the motor and the hydraulic braking force provided by the hydraulic braking system can be distributed in a coordinated mode, and the accuracy of vehicle braking force control is improved.
本申请公开了一种车辆的制动扭矩的分配方法、装置及存储介质,属于车辆控制技术领域。所述方法包括:根据车辆的制动踏板被踩下的踏板行程,确定目标制动扭矩;当车辆满足电液制动条件时,根据目标制动扭矩,为电机和液压制动系统分配扭矩,得到各自被分配的扭矩,按照各自被分配的扭矩对车辆进行制动来获取车辆的实际制动扭矩,根据目标制动扭矩和实际制动扭矩,调整液压制动系统的实际液压制动扭矩,以使实际制动扭矩与目标制动扭矩相等。在驱动电机和液压制动系统共同提供车辆的制动力时,保证了电制动和液压制动之间制动关系的灵活性,能够协调分配电机对应的电制动力和液压制动系统提供的液压制动力,以提高对车辆制动力控制的准确性。
