Fuzzy-Logic Base ABS/GPS Integration for Vehicle Navigation System in Urban Canyons
GPS based vehicle navigation systems have difficulties in tracking vehicles in urban canyons due to poor satellite availability. ABS (Antilock Brake System) Navigation System consists of selfcontained optical encoders mounted on vehicle wheels that can continuously provide accurate short-term positioning information. In this paper, a new concept regarding ABS/GPS integration, based on fuzzy logic is presented. A fuzzy system is used to identify GPS position accuracy based on environment and vehicle dynamic knowledge. The GPS is used as reference during the time it is in a good condition and replaced by ABS positioning system when GPS information is unreliable. The MATLAB simulations manifested an improvement in location precision and the tracking capability in urban canyon conditions.
