The invention relates to a torque control method. According to the method, vehicle state information and mode information are obtained, and prediction of the target acceleration, the flywheel end torque gradient and the flywheel end demand torque value is combined; and further, power output of the power device is adjusted by sending a control instruction to a vehicle control system, so that change of the torque meets the requirement of a control mode. Compared with the prior art, the method has the advantages that the scaling process is simpler and more convenient, and the control object can be adjusted more directly. The method is high in applicability, and various driving systems conforming to constraint adjustment can be optimized through the method. In addition, the invention further discloses a device corresponding to the method, a storage medium and a vehicle.

    本发明通过获取车辆状态信息和模式信息结合目标加速度、飞轮端扭矩梯度及飞轮端需求扭矩值的预测;进而通过向车辆控制系统发送控制指令,调整动力装置的动力输出,使得扭矩的变化符合控制模式的要求。与现有技术相比,本发明的标度过程更加简介方便,对控制对象的调节更加直接。本方法的适用性强,对于符合约束调节的各类驱动系统,均可采用本方法进行优化。此外,本发明还公开了与该方法相应的装置、存储介质和车辆。
