Abstract

The invention relates to a dual-power-source auxiliary system of a hybrid car. The dual-power-source auxiliary system comprises a motor power driven subsystem, an engine power driven subsystem, a power coupling device, wheels and a controller. The motor power driven subsystem comprises a motor, a battery and a first automatic transmission, and the first automatic transmission is connected with the motor and the power coupling device. The engine power driven subsystem comprises a second automatic transmission connected with the power coupling device, a first power source connected with the second automatic transmission, an alternator connected with the second automatic transmission, an automatic clutch connected with the alternator, an engine connected with the automatic clutch and a second power source. The invention further relates to a dual-power-source control method of the hybrid car. By the structure, the first power source and the second power source can adopt matched mechanical steering pumps and air compressors on a conventional fuel-powered car engine, new electric accessories need not to be developed, matching of an expensive power adapter is omitted, and the dual-power-source auxiliary system is simple to operate and wide in application range.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a hybrid electric bus, in particular to a hybrid electric vehicle dual power source auxiliary system and a control method thereof. Background technique [0002] At present, according to the structure of the power transmission system, hybrid vehicles can be divided into three categories: series hybrid vehicles, parallel hybrid vehicles and hybrid hybrid vehicles. [0003] According to whether external power supply is needed for charging, it can be divided into plug-in hybrid and non-plug-in hybrid, among which plug-in hybrid is the development direction of hybrid, and now various manufacturers and research institutions are committed to the research of plug-in hybrid vehicles . [0004] The plug-in hybrid has a pure electric driving mode, so it will be matched with the corresponding electric accessories to ensure the normal operation of its accessories such as power steering and braking. ...
