Engine start control system

An engine start control system for an internal combustion engine of a vehicle, comprising:

• a push switch that is pressable by a user to start the engine;
• a brake sensor that senses depression of a brake pedal of the vehicle when the user depresses the brake pedal a predetermined distance or greater from an initial point;
• and
• an engine start control unit that controls engine start of the engine, wherein:
• the engine start control unit determines that a current operational mode is a normal mode when the brake sensor detects the depression of the brake pedal and is thereby placed in an detected state;
• the engine start control unit enables the engine start when the user performs a predetermined normal time push operation on the push switch in the normal mode;
• the engine start control unit determines that the current operational mode is a fail-safe mode when the brake sensor does not detect the depression of the brake pedal and is thereby placed in an undetected state;
• the engine start control unit enables the engine start when the user performs a predetermined fail-safe push operation on the push switch in the fail-safe mode;
• and
• the fail-safe push operation of the push switch requires an increased work load of the user in comparison to that of the normal time push operation of the push switch.
