Device for controlling automatic stopping of vehicle engine

A vehicular engine automatic stop control apparatus comprising:

• a coast stop controller that performs a coast stop control of stopping an engine in response to a situation where driver's brake pedal operation is above a predetermined threshold value while a vehicle is traveling;
• a road surface gradient sensor that senses a road surface gradient;
• a coast stop control cancellation unit that cancels the coast stop control in response to a situation where a first sensed value of the road surface gradient is above a predetermined cancellation threshold value in absolute value, wherein the first sensed value of the road surface gradient is obtained at a first time instant when the vehicle becomes stationary in a situation where the engine has been stopped by the coast stop controller;
• and
• an idling stop controller that stops the engine in response to a situation where a predetermined condition is satisfied when the vehicle is stationary,
• wherein the coast stop control cancellation unit cancels the coast stop control during a time period from the first time instant to a second time instant when the idling stop controller determines that the engine has been stopped.
