The invention relates to a torque control method, system and device under the overtaking working condition of an electric vehicle and a medium. The method comprises the steps that a radar detects that a low-speed vehicle appears in front, and a driver has the overtaking requirement; carrying out lane changing operation; radar detection is carried out again, and a signal is output to a vehicle control unit VCU; the VCU detects an accelerator pedal signal, the change rate of the accelerator pedal opening degree is larger than a certain value, and the pedal opening degree is larger than a certain value; different driving modes correspond to different driving curves and correspond to different motor external characteristic curve percentages, and the vehicle jumps from the current driving curve to the maximum driving curve, namely the motor external characteristic curve; and the driver reduces the opening degree of the accelerator pedal, an accelerator pedal signal is detected through the VCU, the driving curve is switched to the driving curve corresponding to the driving mode set by the driver, and overtaking is completed. According to the method, the torque potential of the whole vehicle can be released when a driver has an overtaking requirement, so that the driver can finish overtaking more quickly, the driving experience is improved, and the overtaking time is shortened.

    本发明涉及一种电动汽车超车工况下的扭矩控制方法、系统、设备及介质,方法包括通过雷达探测前方出现慢速车辆,驾驶员有超车需求;进行变道操作;再次通过雷达探测,并将信号输出给整车控制器VCU中;VCU检测油门踏板信号,油门踏板开度的变化速率大于一定值,踏板开度大于一定值;不同的驾驶模式对应不同的驾驶曲线,对应不同的电机外特性曲线百分比,车辆从当前驾驶曲线跳转到最大驾驶曲线即电机外特性曲线;驾驶员减小油门踏板开度,通过VCU检测油门踏板信号,驾驶曲线切换为驾驶员设置的驾驶模式对应驾驶曲线,超车完成。本方法可满足驾驶员在有超车需求时,释放整车扭矩潜能,使驾驶员可更快完成超车,增加行车体验,减小超车时间。
