Abstract
An improved accuracy sensory system for vehicle navigation employs a sensor, such as a compass (515), or an odometer (509), for sensing a navigation parameter of a vehicle. A signal is provided from the sensor, having an erroneous component. A model free recognizer, such as a fuzzy inferencing navigation computer (501), is employed to recognize this erroneous behavior. After recognition, the sensor can be recalibrated, or assigned a clearness coefficient. The signal is then combined with other measurements of the same parameter and subjected to map matching before deriving the final navigation variable.
