The invention discloses a torque control method and device of a vehicle, a storage medium and an electronic device, and relates to the technical field of vehicles. The method comprises the steps that the motor rotating speed and the rotor angle of a motor in a vehicle are obtained; in response to the received active short-circuit instruction and the motor rotating speed being greater than a preset threshold value, determining a target current according to the rotor angle, the active short-circuit instruction being used for performing active short-circuit control on the motor, and the target current being used for representing a current of the motor in a rotating coordinate system; determining a target flux linkage value based on the target current and a target relation table; determining a target torque based on the target current and the target flux linkage value; and controlling the torque of the vehicle according to the target torque. The technical problems of high cost, difficult implementation, poor anti-interference performance, poor accuracy, poor stability and poor convergence caused by the fact that the torque of the vehicle is determined by adding a torque sensor or developing a torque estimation method in the prior art are solved.

    本发明公开了一种车辆的转矩控制方法、装置、存储介质及电子装置,涉及车辆技术领域。其中,该方法包括:获取车辆内电机的电机转速和转子角度;响应于接收到主动短路指令且电机转速大于预设阈值,根据转子角度确定目标电流,其中,主动短路指令用于对电机进行主动短路控制,目标电流用于表示电机在旋转坐标系下的电流;基于目标电流和目标关系表确定目标磁链数值;基于目标电流和目标磁链数值确定目标转矩;根据目标转矩对车辆的转矩进行控制。本发明解决了相关技术通过在增加转矩传感器或开发转矩估算法确定车辆的转矩,导致成本较高、不易实现、抗干扰性较差、准确性较差、稳定性较差、收敛性较差的技术问题。
