The invention discloses a vehicle driving motor torque control method and electronic equipment. The method comprises the steps of obtaining required torque of a driving motor, actual rotating speed of the motor and actual acceleration of a vehicle; determining a corresponding maximum torque limit value according to the actual motor rotating speed and the actual acceleration; and taking the minimum value of the required torque and the maximum torque limit value as the final output torque, and controlling the driving motor by adopting the final output torque. According to the invention, the motor output torque can be adjusted actually based on the vehicle acceleration, so that the vehicle is driven at a relatively ideal acceleration, and the vehicle driving feeling is improved. Meanwhile, when the rotating speed of the motor changes drastically and motor control is unstable, motor overcurrent is prone to occurring, however, the torque limiting value is calculated based on the acceleration, torque can be limited in advance under the working condition with the very high motor rotating speed change rate, and the risk of motor overcurrent occurring under the working condition that the vehicle slips very seriously is reduced.
本发明公开一种车辆驱动电机扭矩控制方法及电子设备。方法包括:获取驱动电机的需求扭矩、电机实际转速以及车辆的实际加速度;根据实际电机转速与实际加速度,确定对应的最大扭矩限值;对需求扭矩与最大扭矩限值取最小值作为最终输出扭矩,采用最终输出扭矩控制驱动电机。本发明可以实际的基于车辆加速度对电机输出扭矩进行调节,使车辆保持比较理想的加速度进行驾驶,提升车辆驾驶感受。同时,在电机转速剧烈变化时,电机控制不稳定的话易于发生电机过流,而本发明基于加速度计算扭矩限值,因此对很高的电机转速变化率的工况能够进行扭矩提前限制,降低车辆在发生非常严重打滑的工况下,发生电机过流的风险。
