Abstract:
An engine automatic stop/restart device for an engine of a vehicle, the vehicle having a drive wheel, and a transmission mechanism which transmits a creep force to the drive wheel according to a rotation of the engine, comprising,a motor for starting the engine, a sensor which detects if the transmission mechanism is in a drive range wherein the creep force is transmitted to the drive wheel, a sensor which detects that a brake pedal is depressed, and a microprocessor programmed to: stop the running of the engine automatically when the vehicle is stationary with the brake pedal depressed, determine whether a driver or a vehicle state requires a restart of the engine, restart the engine to increase a rotation speed of the engine rapidly by the motor when the driver requires the restart of the engine, and restart the engine to increase the rotation speed of the engine more slowly by the motor when the vehicle state requires the restart of the engine with the transmission mechanism in the drive range.
