Abstract

Abstract Control system and method for controlling a vehicle or a component of a vehicle in which an inertial reference unit includes accelerometers and gyroscopes which provide data on vehicle motion and a processor processes the data and controls the vehicle or the component of the vehicle based thereon. Movement of the vehicle may be controlled via control over servos, such as a servo associated with the braking system, a servo associated with the drive train or throttle and a servo associated with the steering system. A display to the driver can also be controlled by the processor to provide data on vehicle motion or data or information derived from the data on vehicle motion. Optionally, a Kalman filter is coupled to the processor for optimizing the data on vehicle motion from the inertial reference unit.
