The invention relates to the technical field of new energy vehicles, in particular to a torque control method and device based on torque distribution ratio adjustment, a medium and a vehicle. The method comprises the steps of obtaining a whole vehicle target torque, an original distribution ratio and front and rear motor original torques when a rapid accelerator stepping operation is received; performing gradient and filtering processing on the original torques of the front and rear motors to obtain corresponding request torques of the front and rear motors; judging whether the front motor and the rear motor are in a torque zero-crossing state or not according to the front and rear motor original torques and the front and rear motor request torques; if only one of the front motor and the rear motor is in the torque zero-crossing state, the original distribution ratio is adjusted to obtain a target distribution ratio through the original torque, the request torque and the whole vehicle target torque of the motor in the torque zero-crossing state; and distributing the whole vehicle target torque according to the target distribution ratio to obtain target torques of the front and rear motors. By adopting the method, the phenomenon that the response of the vehicle to the Tip-in is not timely enough can be improved.

    本申请涉及新能源汽车技术领域,尤其是涉及一种基于扭矩分配比调整的扭矩控制方法、装置、介质及车辆。方法包括:在接收到快速踩油门操作时获取整车目标扭矩、原始分配比、前后电机原始扭矩;对前后电机原始扭矩进行梯度及滤波处理,得到对应的前后电机请求扭矩;根据前后电机原始扭矩、前后电机请求扭矩判断前电机、后电机是否处于扭矩过零状态;若前电机和后电机中只有一个处于扭矩过零状态,通过处于扭矩过零状态的电机的原始扭矩、请求扭矩和整车目标扭矩,对原始分配比进行调整得到目标分配比;根据目标分配比对整车目标扭矩进行分配得到前后电机的目标扭矩。采用本方法能够改善车辆对Tip‑in的响应不够及时的现象。
