Automatic sensor azimuth alignment

Image Number 2 for United States Patent #5964822.

This disclosure relates to a system for automatically measuring and compensating for any angle of misalignment of a forward-looking sensor of a vehicle. The sensor provides data representing the azimuth angle and the range of a target such as another vehicle. For each angle and range reading of the sensor, the location point of the target is estimated; after a series of such readings, the trajectory line of the target is estimated. The angle of misalignment is estimated from the angle between the trajectory line and the path of travel of the host vehicle. In subsequent readings of the sensor, the estimated angle of misalignment is subtracted from the measured azimuth angle to produce an accurate azimuth angle of the target. The accurate azimuth angle is provided for use by another unit such as a collision warning system and/or an intelligent cruise control.
