A computer implemented method for determining a road friction condition associated with at least one wheel on a heavy-duty vehicle includes transmitting a radar signal by at least one polarimetric radar transceiver towards a surface supporting the vehicle, and receiving backscatter from the transmitted radar signal, where the radar signal comprises a first polarization component and a second polarization component different from the first polarization component, processing the received backscatter by a processing device to determine a friction parameter related to the road friction condition of the surface, monitoring the friction parameter over time to detect change in the friction parameter, and in case change in the friction parameter is detected, triggering friction estimation by a secondary physical friction estimation system.
