Abstract
An engine start/stop control system for preventing an engine from stopping when a vehicle is traveling. The system includes an IGdriver circuit arranged between a power supply control unit and an IGrelay. The IG1 driver circuit is activated in accordance with an activation signal from the power supply control unit or an output signal of a latch circuit and includes an FET for activating a relay. The latch circuit keeps the FET ON and the relay activated unless the vehicle stops traveling and a start/stop switch is pushed.
