The invention discloses a torque determination method and device, equipment and a storage medium, and belongs to the technical field of vehicles. According to the method, power loss values of a first motor and a second motor at different rotating speeds and different required torques are determined according to power loss conditions of the first motor and the second motor at different rotating speeds and different torques, and then torque distribution coefficients of the first motor and the second motor are determined when a total power loss value is minimum; establishing a corresponding relation among the rotating speed, the total required torque, the torque distribution coefficient of the first motor and the torque distribution coefficient of the second motor, and distributing torque for the first motor and the second motor according to the actual rotating speed, the actual total required torque and the corresponding relation of the vehicle in the running process of the vehicle. In this way, the first motor and the second motor can be in the working state with the minimum power loss, and therefore the endurance mileage of the vehicle is increased.

    本申请公开了一种扭矩确定方法、装置、设备和存储介质,属于车辆技术领域。该方法根据第一电机和第二电机在不同转速和不同扭矩下的功率损失情况,确定第一电机和第二电机在不同转速和不同需求扭矩下的功率损失值,然后确定功率总损失值最小时,第一电机和第二电机的扭矩分配系数,建立转速、需求总扭矩、第一电机的扭矩分配系数和第二电机的扭矩分配系数之间的对应关系,在车辆行驶过程中,根据车辆的实际转速、实际需求总扭矩和对应关系,为第一电机和第二电机分配扭矩,这样就可以使第一电机和第二电机处于功率损失最小的工作状态,从而提高车辆续航里程。
