摘要： A system (110) for estimating an articulation angle of a vehicle combination (199) comprises: a motion sensor (111) for sensing one or more linear and/or angular motion quantities ( y ) of the vehicle combination; and a dynamics-based estimator (113) configured to estimate state variables ( x ) including the articulation angle on the basis of the sensed motion quantities, wherein the dynamics-based estimator is dependent on one or more masses ( m ) and moments of inertia ( J ) of the vehicle combination.

摘要： A wheel end module (140) for a heavy-duty vehicle (100), the wheel end module (140) comprising a processing device (440, 700), a radar module (110) arrange to transmit a radar signal (115) towards a surface (101) supporting the vehicle (100) and to receive backscatter from the radar signal (115), and a load sensing arrangement,
where the processing device (440, 700) is arranged to determine a parameter related to a normal force ( F z ) associated with at least one wheel (102, 310) of the heavy-duty vehicle (100) by the load sensing arrangement,
where the processing device (440, 700) is arranged to determine a parameter related to a friction coefficient ( µ ) of the surface (101) by the radar module (110),
where the processing device (440, 700) is arranged to determine a wheel force generating capability ( F x , F y ) of the at least one wheel (102, 310), based on the normal force ( F z ) related parameter and on the friction coefficient ( µ ) related parameter,
where the wheel end module (140) is arranged to output the wheel force generating capability ( F x , F y ) on an output interface of the wheel end module (140).-

摘要： A computer implemented method for determining a road friction condition associated with at least one wheel (150, 160, 170, 430) on a heavy-duty vehicle (100), the method comprising
transmitting (S1) a radar signal (185) by at least one polarimetric radar transceiver (180) towards a surface (101) supporting the vehicle (100), and receiving backscatter from the transmitted radar signal, where the radar signal (185) comprises a first polarization component and a second polarization component different from the first polarization component,
processing (S2) the received backscatter by a processing device (130) to determine a friction parameter related to the road friction condition of the surface (101),
monitoring (S3) the friction parameter over time to detect change in the friction parameter, and
in case change in the friction parameter is detected,
triggering (S4) friction estimation by a secondary physical friction estimation system.-
