ABSTRACT:
A velocity at the time when the accelerator of a vehicle is released is stored under a certain condition in advance, and the stored vehicle velocity and an actual vehicle velocity are compared. When the actual vehicle velocity becomes greater than the stored vehicle velocity by a predetermined value, the downward inclination of a running road surface is regarded as exceeding a predetermined value, and safety means such as a brake is driven. As compared with a case of employing an inclination angle sensor such as a mercury switch, the device operates accurately without being influenced by a change in the vibration or acceleration of the vehicle.
