ABSTRACT:
An automatic engine stop and start apparatus for automatically stopping and starting an engine is disclosed. When a car starts to move while the engine has been automatically stopped and the car is to be braked, and a car velocity exceeds a predetermined speed and a booster pressure of a brake falls below a predetermined level, the apparatus issues an alarm. To this end, the apparatus includes a car velocity sensor for detecting the car velocity, a slope sensor for detecting the necessity of the brake for the car, a negative pressure switch fordetecting the booster pressure of the brake and alarm means responsive to detection outputs of those sensors.
