Abstract

A method performed in a control unit of a heavy-duty vehicle for estimating road friction, the method comprising, while the vehicle is in motion, generating a steering pulse having a limited time duration and a limited magnitude, measuring a response by the vehicle to the steering pulse, and estimating a road friction value based on the measured response by the vehicle.
