The invention discloses a single-clutch dual-motor power gear shifting driving system which is characterized in that an ISG (integrated starter generator) motor is directly connected with an engine, a clutch is positioned between the ISG motor and a gearbox, an input shaft moves through a synchronizer, and speed ratio adjustment and gear switching can be realized. The driving TM motor is located on the output shaft and transmits power to the wheel end through the reduction ratio. Compared with the prior art, after the TM motor is arranged on the gear shifting mechanism, the proper speed ratio and motor are selected, TM independent pure electric driving is achieved, and pure electric power interruption of gear shifting is avoided; according to the scheme, series efficient charging and driving are achieved, good drivability and economical efficiency are achieved at low speed and low electric quantity, the engine can be started through a single motor, and the drivability problem during sliding friction starting is avoided; according to the scheme, the simple AMT system is adopted, the functions of pure electric running, series running, parallel running and the like are achieved, and the control method has obvious advantages in the aspects of control and cost. The invention further provides a vehicle and a single-clutch dual-motor power gear shifting driving method.

    本发明公开了一种单离合器双电机动力换挡驱动系统,ISG电机和发动机直连,离合器位于ISG和变速箱之间,输入轴上通过同步器移动,可以实现速比调整、档位切换。驱动TM电机位于输出轴,通过减速比将动力传递到轮端。相比现有技术,本发明将TM电机布置在换挡机构之后,选择合适速比及电机,实现TM单独纯电驱动,避免纯电动力中断换挡;本方案实现串联高效充电和驱动,在低速低电量拥有较好的驾驶性和经济性,也可利用单独电机启动发动机,避免滑磨启动时的驾驶性问题;本方案采用的较为简洁的AMT系统,实现纯电、串联、并联行驶等功能,在控制和成本上有较为明显的优势。本发明还提供了一种车辆和单离合器双电机动力换挡驱动方法。
