The invention discloses a hybrid electric vehicle gear shifting torque control method, equipment, a storage medium and a device. When a gear shifting signal is received, wheel end required torque is determined according to a target gear of a target vehicle; if the target vehicle is in the pure electric gear shifting mode, a TM motor and an ISG motor are controlled to conduct torque interaction according to the wheel end demand torque so as to meet the wheel end demand torque; and if the hybrid power gear shifting mode is in the hybrid power gear shifting mode, the output torque of an engine is controlled to conduct torque interaction according to the wheel end demand torque so as to meet the wheel end demand torque. The torque coordination control strategy is used in the gear shifting process to carry out torque compensation so as to meet the torque requirement of a driver, and compared with the prior art that power is interrupted in the gear shifting process of a synchronizer of a power split hybrid power system, the user experience is poor, and the gear shifting efficiency is high. The problem of power interruption in the synchronizer gear shifting process in a pure electric gear shifting mode and a hybrid power gear shifting mode is effectively solved, and the drivability of the whole vehicle gear shifting process is improved.

    本发明公开了一种混动汽车换挡扭矩控制方法、设备、存储介质及装置,本发明通过在接收到换挡信号时,根据目标车辆的目标档位确定轮端需求扭矩;若目标车辆处于纯电换挡模式时,根据轮端需求扭矩控制TM电机和ISG电机进行扭矩交互,以满足轮端需求扭矩;若处于混动换挡模式时,根据所述轮端需求扭矩控制发动机的输出扭矩进行扭矩交互,以满足轮端需求扭矩。由于本发明通过换档过程中使用扭矩协调控制策略,进行扭矩补偿,以满足驾驶员的扭矩需求,相较于现有技术中功率分流混动系统同步器换挡过程中动力中断,导致用户体验感差,本发明有效解决纯电换挡模式以及混动换挡模式下同步器换挡过程的动力中断问题,提升整车换档过程的驾驶性。
