Abstract
A method performed by a network node for estimating a relative tire friction performance of a number of vehicles is disclosed. The network node and a communication unit may be located in each vehicle and may be part of a communications network. The method may include receiving continuously tire-to-road friction values and corresponding VSPs (Vehicle State Parameters) from each communication unit. Each VSP may include the geographical location and time at which tire-to-road friction value is measured. The method may further include determining that a tire-to-road friction value of a first vehicle is comparative to the tire-to-road friction value of a second vehicle. The method may also include comparing the tire-to-road friction value of the first vehicle to the tire-to-road friction value of the second vehicle, and determining a ranking of the relative tire friction performance of the first vehicle in relation to the second vehicle based on the comparison.
