This paper has described the current results of the ongoing FRICTI@N project. Road friction is an important parameter in vehicle control affecting how much steering, braking and acceleration can be done with the vehicle. However, on-line friction estimation is also a difficult task to be successfully done in all driving situations and weather conditions. Nevertheless, if this information would be available continuously for all vehicle applications, vehicle safety would be clearly improved in many ways. Of vehicle on-board applications the main benefiting application group is probably Active Safety, because ESP etc. algorithms are more accurate when friction available is better known. Application group called ADAS will benefit also from more accurate friction information, especially of road conditions ahead of the vehicle (EFF). Also Advanced Protective Safety application group will benefit thanks to e.g. more accurate time-to-crash estimation. Co-operative IVIS and ADAS applications will also benefit from the project results, since the better individual vehicles .probe. the road friction, the easier it is to make important friction information available for other vehicles. One clear benefit of the project is, that friction potential is estimated even if the vehicle is driving straight without sliding, thus providing more information of this important road parameter to co-operative systems.
