The invention provides a torque distribution system for double electric drive axles of a vehicle, which comprises a first electric drive axle and a second electric drive axle, which are respectively provided with a first gearbox, a second gearbox, a first motor and a second motor, a vehicle controller in communication with the first and second electric axles configured to determine a number of electric axles driving the vehicle based on the requested torque; the first counter and the second counter are respectively used for counting and accumulating the working durations of the first electric drive axle and the second electric drive axle; the vehicle controller is configured to appoint the electric drive axle with the shorter accumulated working time to drive the vehicle based on the comparison between the accumulated working time of the first electric drive axle and the accumulated working time of the second electric drive axle when it is determined that one electric drive axle is used for driving the vehicle. The invention further provides a corresponding torque distribution method and a machine readable storage medium. Instructions for implementing the torque distribution method when the instructions are executed by the processor are stored on the medium.
本发明提出用于车辆双电驱桥的扭矩分配系统,包括:第一和第二电驱桥,其上分别设置有第一和第二变速箱和对相应变速箱驱动的第一和第二电机;车辆控制器,其与第一和第二电驱桥通信,被配置为基于请求的扭矩确定驱动车辆的电驱桥的数量;以及第一和第二计数器,分别用于对第一和第二电驱桥的工作时长进行计数和累计;车辆控制器被配置为:当确定以一个电驱桥驱动车辆时,基于第一电驱桥的累计工作时长与第二电驱桥的累计工作时长间的比较,指定累计工作时长较少的电驱桥对车辆进行驱动。本发明还提出相应的扭矩分配方法及机器可读存储介质,介质上存储有被处理器执行时实施所述扭矩分配方法的指令。
