ROAD IDENTIFICATION FOR ITS-INTEGRATED SYSTEMS OF AUTOMOTIVE ACTIVE SAFETY

This paper analyze different aspects of active safety controls for cars with special emphasis on using fuzzy logic applications to determine the degree of friction between tires and the road. First, it describes the problem of road identification in active safety control. The fuzzy logic application uses off-board sensors to identify the coefficient of the friction between the tires and the road surface, taking into account elements such as the texture of the road, its profile, the normal forces acting on tire-road contacts, and the vehicle's velocity during the maneuver. Also described are algorithms for active safety systems with pre-extreme control. To estimate the road-tire friction coefficient, it makes sense to simultaneously apply the fuzzy controllers with roughness data and environmental elements. Further research will involve the investigation of the processes at the tire-road interaction in the pre-extreme area of dependence between tire slip and wheel forces.
