Abstract
An engine start system has a rotating electrical machine, a starter motor, an engine ECU and an ISG controller. The rotating electrical machine is connected to an output shaft of an engine. The starter motor drives the engine to be restarted. The engine ECU controls the engine operation. The ISG controller instructs an inverter when the rotating electrical machine performs power running and regenerative power generation. The ISG controller communicates with the engine ECU, and adjusts the operation of the starter motor and the rotating electrical machine. When receiving an engine restart request, the ISG controller drives at least one of the starter motor and the rotating electrical machine so as to restart the engine.
