The invention discloses a method for improving comfort of a vehicle passing through a deceleration strip, a motor controller and the vehicle, relates to the field of new energy automobiles, and can be applied to pure electric vehicles and hybrid vehicles. The method is used for adjusting the output torque of a driving motor to improve the driving comfort in the process that the electric vehicle passes through the deceleration strip, and comprises the step of correspondingly adjusting the output torque of the driving motor corresponding to wheels according to the change of the opening degree of an accelerator pedal before the first moment when the wheels of the electric vehicle make contact with the deceleration strip. And after the second moment when the wheels leave the ground after passing through the deceleration strip, before the third moment when the wheels fall to the ground, and before the opening degree of the accelerator pedal is changed, the output torque of the driving motor corresponding to the wheels is actively reduced. And after the third moment, the output torque of the driving motor corresponding to the wheels is actively increased before the opening degree of the accelerator pedal is changed. According to the scheme, the road surface change is quickly sensed, the torque of the driving motor is quickly adjusted, and the safety and comfort of the vehicle are improved.
一种提高车辆通过减速带舒适性的方法、电机控制器和车辆,涉及新能源汽车领域,可应用于纯电动车辆及混动车辆。该方法用于在电动车辆通过减速带的过程中调节驱动电机的输出扭矩提高驾乘舒适性,方法包括在电动车辆的车轮接触减速带的第一时刻之前,根据加速踏板的开度的变化相应地调节车轮对应的驱动电机输出的扭矩。在车轮通过减速带后车轮离地的第二时刻之后、车轮落地的第三时刻之前,在加速踏板的开度变化之前主动减少车轮对应的驱动电机的输出扭矩。在第三时刻之后,在加速踏板的开度变化之前主动增大车轮对应的驱动电机的输出扭矩。根据本方案,快速感知路面变化,迅速调整驱动电机扭矩,提高车辆的安全性和舒适性。
