摘要： A vehicle biaxial parallel electric drive system and a gear shifting control method thereof. The drive system comprises a drive motor I (1), a drive motor II (15), and an automated mechanical transmission. The automated mechanical transmission comprises a first-gear gear pair (3, 7), a second-gear gear pair (13, 7), a third-gear gear pair (5, 8), a fourth-gear gear pair (10, 8), an engaging sleeve I (4), an engaging sleeve II (12), a transmission input shaft I (6), a transmission input shaft II (11), and a transmission output shaft III (9). The drive system comprises drive motors and an automated mechanical transmission, is simple in structure and reasonably arranged, has high acceleration and gradeability, and implements smooth gear shifting, without any power interruption. By using the gear shifting control method, the continuity of generation of power required for driving can be ensured in a gear shifting process. In addition, kinetic energy ensured during a vehicle traveling process can be converted to electric energy during a braking process, thereby reducing the losses of electric energy, so that the battery costs are reduced and the driving range of the vehicle is improved.

摘要： Disclosed are a driving system of a dual-motor dual-shaft input gearbox and a gear shift control method therefor. The system comprises a driving motor I (1), a driving motor II (21) and an electrically controlled mechanical automatic transmission. The electrically controlled mechanical automatic transmission comprises a first gear set (4, 18, 12, 10), a second gear set (17, 6, 7, 15), a third gear set (4, 18, 14, 8), a fourth gear (17), a clutch collar I (16), a clutch collar II (9), a transmission input shaft I (3), a transmission input shaft II (19) and a transmission output shaft (11). The electrically controlled mechanical automatic transmission provides 3 gears for the power output from the driving motor I (1) and the driving motor II (21). By the coupling of the driving motor I (1), the driving motor II (21) and the electrically controlled mechanical automatic transmission and the driving of the driving motor I (1) and the driving motor II (21), the switching between the 3 gears can be achieved. The system saves the vehicle layout space, the gears do not affect each other, the requirements for bearings and gear speeds are not high, and the service life is prolonged.
