Abstract

The invention belongs to the technical field of vehicle power systems, and provides a power system, a power system control method and a vehicle. The power system comprises a power conversion device which comprises an engine and a gearbox connected with the engine and provided with a power output end, and a driving device comprising a motor with a central shaft and a power supply for supplying power to the motor to drive the central shaft to rotate; one end of the central shaft is set as a driving input end, and the other end of the central shaft is set as a driving output end; and the driving input end is connected with the power output end, and the power output end is used for outputting torque to the driving input end. The driving device is arranged between the power conversion device and the speed reducer, when the driving device works, torque can be added to the driving output end, so that the input torque of the speed reduction input end can be increased.

Description

technical field [0001] The present application belongs to the technical field of vehicle power systems, and in particular, relates to power systems, power system control methods and vehicles. Background technique [0002] In related technologies, the key transmission device in a hybrid system vehicle is the gearbox. In the existing transmission mode, the design of the gearbox is upgraded respectively, including but not limited to parallel and series connection of motors in the gearbox to improve the vehicle. performance. Among them, such as figure 1 A hybrid powertrain and vehicle 100' having the hybrid powertrain is shown including a transmission line that transmits input power from a power motor 110' and a power engine 120' through a power transmission 130', but is subject to The diameter of the output shaft 140' limited to the power gearbox 130' cannot be increased all the time, therefore, it cannot be implemented when the total torque transmitted is too large. Conten...
