ABSTRACT:
A decelerometer is provided for detecting and measuring inertial deceleration and acceleration of a vehicle moving in a first direction and alternatively moving in a second direction which opposes the first direction. The decelerometer uses a tilt sensor which changes voltage as the tilt sensor is rotated clockwise or counter clockwise or is otherwise tilted from a level position. Two voltage outputs from the tilt sensor are processed to convert from AC to DC and from DC to digital information, which subsequently is processed by a processing unit for decisions to be made relative to accelerating, decelerating, and braking of the vehicle.
