The invention relates to the technical field of new energy vehicles, in particular to a vehicle and a driving motor control method and device thereof, a controller and a storage medium. The method comprises the steps that gear shifting operation of a corresponding gear shifting rod during gear shifting of the vehicle is monitored, and when the gear shifting operation meets a preset gear shifting condition, corresponding target pre-tightening force is determined according to a target gear corresponding to the gear shifting operation; controlling a driving motor of the vehicle to output corresponding driving torque according to the target pre-tightening force, recognizing a gear shifting intention of a driver in advance, and adjusting torque reversing and a torque target value of the driving motor in advance by utilizing the target pre-tightening force, so as to simulate a synchronization process of pre-engaging a synchronization ring of a synchronizer, and reduce the speed of the vehicle under ramp, in-situ or low-speed gear shifting. Mechanical impact of a motor output torque gear matching surface is caused by quick-release braking and insufficient braking force.
本发明涉及新能源车辆技术领域,尤其涉及一种车辆及其驱动电机控制方法、装置、控制器、存储介质。该方法监测车辆换挡时对应的换挡杆的换挡操作,在换挡操作满足预设的换挡条件时,根据换挡操作对应的目标档位,确定对应的目标预紧力;根据目标预紧力控制车辆的驱动电机输出对应的驱动扭矩,通过提前识别驾驶员的换档意图,利用目标预紧力提前调整驱动电机的扭矩换向及扭矩目标值,以实现模拟同步器预挂同步环的同步过程,减少坡道、原地或低车速换档下,由于快松制动及制动力不足导致电机输出扭矩齿轮配合面的机械冲击。
