Description
Technical field
The utility model relates to hybrid vehicle, and especially plug-in hybrid-power automobile is specifically related to automobile-used double-motor and multi-clutch hybrid electric drive unit and corresponding multistage hybrid electric drive system.
Background technology
Become today that auto trade develops main flow in energy-conservation and environmental protection, hybrid vehicle has become the key core technology that various countries automobile vendor greatly develops.Wherein, the plug-in hybrid solution as except that pure oil-efficient hybrid power solution electronic, is just praised highly by all big enterprises.Plug-in hybrid mainly is made up of driving engine and one or two motor of a relatively little discharge capacity, wherein motor is responsible under middle low speed realizing that pure electric-powered output and braking energy reclaim generally speaking, and realizes that when needed engine starting and driving engine generate electricity by motor where necessary or participate in function such as power driven.
In the prior art, mainly contain following several connecting method between driving engine in the above-mentioned plug-in hybrid drive system and the motor:
One, tandem plan, the Chev Volt hybrid power concept car of releasing as General Motors Coporation belongs to the plug-in hybrid car, be Plug-in Hybrid Electric Vehicle, can use household outlet (for example 110V/220V power supply) to battery charge in the hybrid electric drive system, plug-in hybrid-power automobile has longer pure motor driving mileage than full blended electric power automobile, when battery was in low electric weight, driving engine will start to generate electricity provided power for vehicle.But the driving engine of this automobile is not participated in work directly, and the engine driven generators generating could drive main drive motor during the length distance travel behind twice ac-dc conversion, and the work efficiency of engine power output is on the low side; For guaranteeing car load acceleration/grade climbing performance, the main drive motor and the power of battery require higher in addition, and corresponding auto cost is had relatively high expectations.
