The invention discloses a driving torque distribution method, device and equipment of a vehicle and a medium. The driving torque distribution method comprises the steps that when a vehicle is started, a first motor connected with a first constant-speed-ratio speed reducer in a first drive axle and a third motor connected with a second constant-speed-ratio speed reducer in a second drive axle are controlled to be started; according to the real-time opening degree of an accelerator pedal after the vehicle is started, the real-time required torque is determined; acquiring a real-time vehicle speed after the vehicle is started; according to the real-time required torque and the real-time vehicle speed, the starting state of a second motor connected with a first gearbox in a first drive axle and the starting state of a fourth motor connected with a second gearbox in a second drive axle are controlled; and controlling the real-time output torque of the first motor, the second motor, the third motor and the fourth motor according to the starting states of the first motor, the second motor, the third motor and the fourth motor. By adopting the driving torque distribution method, the dynamic property and the economical efficiency of the whole vehicle can be considered.

    本发明公开了一种车辆的驱动扭矩分配方法、装置、设备及介质。该驱动扭矩分配方法包括:在车辆启动时,控制第一驱动桥中与第一定速比减速器连接的第一电机和第二驱动桥中与第二定速比减速器连接的第三电机启动;根据车辆启动后的实时油门踏板开度确定实时需求扭矩;获取车辆启动后的实时车速;根据实时需求扭矩和实时车速控制第一驱动桥中与第一变速箱连接的第二电机和第二驱动桥中与第二变速箱连接的第四电机的启动状态;根据第一电机、第二电机、第三电机和第四电机的启动状态控制第一电机、第二电机、第三电机和第四电机的实时输出扭矩。通过采用上述驱动扭矩分配方法可兼顾整车的动力性和经济性。
