The invention relates to the technical field of vehicles, in particular to a torque control method and device for a hybrid vehicle, the vehicle and a storage medium, and the method comprises the steps that whether the vehicle is in a hybrid working mode or not is judged; if the vehicle is in the hybrid working mode, the working state of the vehicle is obtained, and the maximum torque reduction amount of an engine, the maximum torque reduction amount of a motor and the torque reduction amount of a transmission under the condition that the drivability of the vehicle meets the preset optimal condition are obtained based on the working state; and torque distribution is conducted on the motor and/or the engine according to the maximum torque reduction amount of the engine, the maximum torque reduction amount of the motor and the torque reduction amount of the transmission. Therefore, the problem that in the P2 configuration vehicle hybrid driving mode, the torque reduction mode of the transmission under the gear shifting working condition is single, and consequently the power performance and the optimal gear shifting quality of the whole vehicle cannot be brought into full play is solved, the overheat risk of the clutch during gear shifting of the transmission can be eliminated, and meanwhile the driving performance and the power performance of the vehicle can be guaranteed to the maximum extent.
本申请涉及车辆技术领域,特别涉及一种混动车辆的扭矩控制方法、装置、车辆及存储介质,其中,方法包括:判断车辆是否处于混动工作模式;若车辆处于混动工作模式,则获取车辆的工作状态,并基于工作状态获取发动机的最大降扭量、电机的最大降扭量和车辆的驾驶性满足预设最佳条件下变速器的降扭量;根据发动机的最大降扭量、电机的最大降扭量和变速器的降扭量对电机和/或发动机进行扭矩分配。由此,解决了P2构型车辆混动行驶模式下,换挡工况变速器降扭量模式单一,导致无法充分发挥整车动力性及最优换挡品质的问题,可以消除变速器换挡期间离合器过热风险的同时,最大限度的保证车辆的驾驶性能及动力性能。
