Design of powertrain control system for parallel hybrid electric vehicle
Abstract: Hybrid vehicles combine traditional, internal combustion engines and pure electric vehicles with advanced control technology as the hub, which has the advantages of both the internal-combustion engine and the pure electric vehicle, the two. Because of the help of an electric motor, it can reduce fuel consumption and shut down internal combustion engines. Only battery drivers are used to achieve the effect of not polluting the gas.
The driving power sources of parallel hybrid electric vehicles are supplied by batteries and motors. The control system between the various energy source of effective energy distribution, so the vehicle dynamic performance and fuel economy depends on the power control system design; and has very important influence to work efficiency and
coordination between the control unit for vehicle. The control system requirements of this design effectively, and use MATLAB/SIMULINK simulation interface based on ADVISOR software, make the control unit according to the real-time demand of power driven power allocation, while ensuring the driving performance, make full use of battery power, in order to save fuel consumption and improve vehicle fuel economy.
