According to the torque zero-crossing control method for the new energy automobile, whether torque zero-crossing control needs to be executed or not is judged by comparing the actual torque of the motor with the required torque of the motor, and after the actual torque of the motor is zero-crossing and after the actual torque of the motor is zero-crossing, the actual torque of the motor is controlled to be kept at a preset torque M within set time T1, under the condition that the gear is not stressed, the actual torque of the motor is zero, tooth leaning is conducted through inertia within the set time T2, impact caused by tooth leaning when the torque crosses zero can be greatly reduced, the preset torque M, the preset time T1 and the preset time T2 can be adjusted according to the motor and requirements, the applicability is wide, the driving performance is optimized, and the driving experience is improved.

    本发明一种新能源汽车扭矩过零的控制方法,通过电机的实际扭矩与电机的需求扭矩对比,判断是否需要执行扭矩过零控制,电机的实际扭矩过零后,电机的实际扭矩过零后,在设定时间T1内,控制电机的实际扭矩保持一个预设扭矩M,在齿轮在不受力的情况下,电机的实际扭矩为零,并保持设定时间T2内,利用惯性进行靠齿,可大幅降低扭矩过零时靠齿带来的冲击,预设的扭矩M,时间T1、T2可以依据电机和需求进行调整,适用性广泛,优化驾驶性能,提高驾驶体验。
