The invention provides a vehicle torque determination method and device, a vehicle and a readable storage medium. The determination method comprises the steps that the real-time remaining electric quantity of the vehicle is obtained; a cost row or a cost column corresponding to the real-time residual electric quantity is searched from a pre-constructed cost matrix, the cost matrix records the cost rows or the cost columns corresponding to the multiple different residual electric quantities respectively, and the cost rows or the cost columns record the energy consumption cost corresponding to the multiple different torques respectively; and searching the minimum cost from the energy consumption cost recorded in the cost row or the cost column, and taking the torque corresponding to the minimum cost as the current output torque of the vehicle. The current output torque of the vehicle can be calculated with the minimum cost based on the real-time remaining electric quantity of the vehicle, and the economical efficiency of the whole vehicle can be improved.

    本发明提供了一种车辆扭矩的确定方法及装置、车辆、可读存储介质,该确定方法包括:获取车辆的实时剩余电量;从预先构建的成本矩阵中查找与实时剩余电量对应的成本行或成本列,其中,成本矩阵记录有多个不同剩余电量分别对应的成本行或成本列,成本行或成本列记录有多个不同扭矩分别对应的能耗成本;从成本行或成本列记录的能耗成本中查找最小成本,将最小成本对应的扭矩作为车辆当前的输出扭矩。本发明能够实现基于车辆的实时剩余电量以最小成本计算车辆当前的输出扭矩,能够提高整车的经济性。
