Abstract
Nowadays hybrid electric vehicle (HEV) has drawn attention of car manufacturer since it provides high efficiency, clean and safe transportation. The appropriate management of all components in such a vehicle is very controversial. Control system of HEV is responsible of supervisory control of the power train, including energy flow control based on the defined control strategy, communication between components, protection against dangerous situations, startup of subsystems and performance management of the entire vehicle. Vehicle Control Software (VCS) is designed and implemented as the central control system of a hybrid electric city bus in “Vehicle, Fuel, and Environment Research Institute (VFERI)”, University of Tehran, Iran. CAN protocol is used for data communication between the VCS and vehicle components. The VCS performance is evaluated with HIL testing method and the results reveal the acceptable performance and effectiveness of the VCS.
