The invention discloses a torque control method and device of a hybrid power vehicle and an engineering vehicle, and the torque control method of the hybrid power vehicle comprises the steps that a driving mode is obtained; when the driving mode is a mixed mode, obtaining a total torque demand; motor torque output by the motor and engine torque output by the engine are obtained according to the total torque requirement and the actual working condition of the vehicle; and according to the first torque change condition of the motor torque and the second torque change condition of the engine, the target torque of the motor is adjusted, so that the target output torque of the motor and the target output torque of the engine are obtained. The problem that the vehicle is unstable due to sudden change of the engine torque and the motor torque when the state of the vehicle changes can be solved.

    本申请公开了一种混合动力车辆的扭矩控制方法、装置及工程车辆,其中,所述混合动力车辆的扭矩控制方法包括:获取驱动模式;当所述驱动模式为混合模式时,获取总扭矩需求;根据所述总扭矩需求和车辆实际工况,获取所述电机输出的电机扭矩和所述发动机输出的发动机扭矩;以及根据所述电机扭矩的第一扭矩变化情况和所述发动机的第二扭矩变化情况,调整所述电机的目标扭矩,以得到所述电机的目标输出扭矩和所述发动机的目标输出扭矩。本申请可以解决车辆状态变化时发动机扭矩和电机扭矩的突变导致车辆不稳定的问题。
