The invention discloses a motor torque determination method and device, equipment, a medium and a program product, and is applied to the field of vehicle control. The method comprises the following steps: acquiring first motion state data of a vehicle, wherein the first motion state data comprises a first vehicle running speed and a first steering wheel rotation angle; according to the first vehicle running speed, a first torque mapping curved surface corresponding to a first vehicle running speed interval where the first vehicle running speed is located is determined, and the first torque mapping curved surface is used for representing the mapping relation between the motion state data and the motor torque in the first vehicle running speed interval; the motion state data comprises a vehicle driving speed and a steering wheel rotation angle; and determining the motor torque mapped with the first steering wheel rotation angle and the first vehicle running speed in the first torque mapping curved surface as the motor torque of the vehicle. The method can solve the problem that vehicle steering is affected due to inaccurate motor torque.

    本申请公开了一种电动机扭矩的确定方法、装置、设备、介质及程序产品,应用于车辆控制领域。该方法包括:获取车辆的第一运动状态数据,第一运动状态数据包括第一车辆行驶速度和第一方向盘转动角度;根据第一车辆行驶速度,确定与第一车辆行驶速度所处第一车辆行驶速度区间对应的第一扭矩映射曲面,第一扭矩映射曲面用于表征在第一车辆行驶速度区间内,运动状态数据和电动机扭矩之间的映射关系,运动状态数据包括车辆行驶速度和方向盘转动角度;将第一扭矩映射曲面中与第一方向盘转动角度和第一车辆行驶速度映射的电动机扭矩确定为车辆的电动机扭矩。该方法能够解决电动机扭矩不准确,影响车辆转向的问题。
