Abstract

The invention discloses a series-parallel type hybrid power car system based on an AMT and a control method. The system comprises a BSG motor, an engine, the AMT, a GMG motor, a drive axle, a hybrid control unit, a sub controller unit and a power battery. The output end of the BSG motor is connected with the input end of the engine, the output end of the engine is connected with the first input end of the AMT, the output end of the AMT is connected with the input end of the drive axle, the second input end of the AMT is connected with the output end of the GMG motor, the output end of the power battery is connected with the input end of the BSG motor and the input end of the GMG motor, the output end of the hybrid control unit is connected with the input end of the sub controller unit, andthe output end of the sub controller unit is connected with input ends of the BSG motor, the engine, the GMG motor and the power battery. According to the car system and the control method, power failures and insufficient electric amount in the vehicle gear shifting process can be overcome, a vehicle can be controlled to adapt to different working conditions, and running capacity of the vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to an AMT-based parallel hybrid vehicle system and a control method. Background technique [0002] Electromechanical Automatic Transmission (AMT for short), that is, power combiner, uses advanced electronic technology to transform the traditional manual transmission, not only retains the advantages of high efficiency and low cost of the original gear transmission, but also has a hydraulic automatic transmission Adopt all the advantages brought by automatic gear shifting, but because of the power interruption problem when the car changes gears, it cannot be widely used. [0003] A hybrid electric vehicle (PHEV for short) is composed of three major powertrains: an engine, an electric / engine and a drive motor. Power combiner Power combined PHEV, electric / engine installation and engine output (referred to as P0 motor structure), generally only used for quick start and power gen...
