The invention relates to the technical field of vehicles, and discloses a torque control method and device for a hybrid power vehicle, the vehicle and a storage medium, the method comprises the steps that working condition parameters of power sources are obtained, and the power sources comprise an engine, a P1 motor and a P3 motor; if a target power source of which the working condition parameter meets the corresponding preset detection condition exists in the power sources, calculating a target real torque of the target power source; obtaining the current output torque of the target power source; based on the difference value between the target real torque and the current output torque, the torque deviation of the target power source under the current operation rotating speed and the current output torque is obtained; storing the torque deviation into a torque precision look-up table corresponding to the target power source, wherein the torque precision look-up table is used for storing the torque deviation of the target power source at different operation rotating speeds and torques; and controlling the torque of the target power source based on the torque precision look-up table. The problem that the torque control precision of the power source of the P13 configuration hybrid power vehicle is low can be solved.

    本发明涉及车辆技术领域,公开了混合动力车辆的扭矩控制方法、装置、车辆及存储介质,该方法包括:获取动力源的工况参数,动力源包括发动机、P1电机和P3电机;若动力源中存在工况参数满足对应的预设检测条件的目标动力源,则计算目标动力源的目标真实扭矩;获取目标动力源的当前输出扭矩;基于目标真实扭矩与当前输出扭矩的差值,得到目标动力源在当前运行转速和当前输出扭矩下的扭矩偏差;将扭矩偏差存储至目标动力源对应的扭矩精度查询表中,扭矩精度查询表用于存储目标动力源在不同运行转速和扭矩下的扭矩偏差;基于扭矩精度查询表对目标动力源的扭矩进行控制。本发明能够解决P13构型混合动力车辆的动力源的扭矩控制精度较低的问题。
