The engine is restarted by a starter which is driven in response to an engine start signal. In automatically restarting the engine, the engine start signal is generated when restart conditions are fulfilled and a starter command is generated in a microcomputer. An operation of a clutch pedal is one of the restart conditions. The clutch pedal is provided therearound with a lower switch and an upper switch to detect an amount of a depression of the clutch pedal.
