Abstract
Abstract An inclination sensor provides means for detection of dangerous attitudes of vehicles, such as road and off-road vehicles including farm tractors, earth-moving equipment, and the like, whether caused by negligence on the part of the operator or by accident. The sensor provides a warning signal or automatically controls the vehicle so that it does not upset thereby endangering the life of the operator or others in its vicinity.
