Abstract
The Idle Stop and Go (ISG) system is a technology that turns the engine off when the vehicle stops and turns it on when the vehicle starts to reduce fuel consumption. City buses have longer idling time than other vehicles have because city buses stop at every bus station; for this reason, the ISG system is more effective for use in city buses to reduce fuel consumption. In addition to some hardware modifications, a controller is required for applying the ISG system to in-use city buses. This study focuses on developing an ISG control hardware and software. The controller communicates with the ECU (Engine Control Unit) and stops fuel injection when necessary. The engine stop conditions consider battery state of charge, road gradient and coolant temperature are investigated and introduced.
