Design of Extended-Range Electric Vehicle Integrated Control System Based on Rapid Prototype Technology

Based on Motohawk rapid prototype development platform and “Development to Production (D2P)”development process, an integrated control system has been built, adapting to the principle and configuration of extended-range electric vehicle. This control system integrated traditional vehicle controller, drive motor controller, APU controller, engine controller and generator controller. The development of this control system is based on ControlCore underlying operation system and designed by Simulink/Stateflow software. Production-level automotive ECU has also been used as the hardware platform. This development method can significantly simplify the topology structure of control system, decrease the develop cycle of extended-range electric vehicle, and reduce the cost in development, production and aftermarket maintenance.
