Abstract
A vehicle safety device designed to reliably prevent uncontrolled travel or runaway of a vehicle when a collision accident occurs. A breaker is connected in a current path between a battery and a controller. In a processing section of a distance measuring unit, a time difference between the moment at which a laser light emitting section emits light and the moment at which a laser light receiving section receives light is detected and the distance and the relative speed between the vehicle and an object against which the vehicle may collide are calculated. When the distance between the vehicle and the object becomes zero while the relative speed between the vehicle and the object is larger than a predetermined value, the processing section determines that a collision has occurred, and supplies a control signal to the breaker to open the same.
