Abstract

A drive control section automatically stops an engine by stopping fuel injection and by closing a throttle valve that adjusts the amount of intake air when a predetermined specified condition is satisfied. A stopping-angle detection section detects a crank angle when the engine is automatically stopped as a stopping angle. The drive control section cranks the engine before an in-cylinder negative pressure period, in which pressure in a cylinder of the engine is negative pressure, elapses after starting to automatically stop the engine if the stopping angle is outside an allowable crank-angle range in which it is possible to restart the engine by cranking the engine by the motor generator.
