Abstract

The invention relates to the field of vehicle hybrid power, and discloses a vehicle hybrid power driving device comprising an engine, a dual-motor power module and a dual-input shaft transmission. Thedual-motor power module comprises a shell, a first motor, a second motor, a first transmission assembly and a second transmission assembly; the dual-input shaft transmission includes a first input shaft, a second input shaft and transmission devices; and the engine is connected to the first motor, and the hybrid power output end is connected with the first input shaft and transmits power to vehicle wheels through the corresponding transmission device, the second motor is connected to the second input shaft and transmits power to the vehicle wheels through the corresponding transmission device, and a brake is arranged between the power output end of the engine and the shell. The vehicle hybrid power driving device solves the problems that a hybrid power system in the prior art is complex in structure, high in power consumption, poor in acceleration, poor in shifting quality and high in control difficulty, and random switching control over hybrid power drive and pure electric drive is difficult to achieve.

Description

Technical field [0001] The invention relates to the field of vehicle hybrid power, and discloses an automobile hybrid power driving device. Background technique [0002] Currently on the market, most of the hybrid power based on the improvement of the automatic transmission is to add a motor between the engine and the transmission, or to connect a motor in parallel with a certain gear of the automatic transmission. Application number 2010100025104 discloses a hybrid powertrain and dual-clutch transmission. The principle is to add a motor and a clutch between the original DCT and the engine, which can realize pure electric drive, braking energy recovery, acceleration and torque increase, etc. Features. The disadvantage is that dual-clutch gear shifting is still needed, motor speed cannot be relied on, shifting quality is poor, and software control is difficult. [0003] Application No. 2004101024688 discloses a dual-clutch transmission device for a hybrid electric vehicle and a me...
