摘要： A method for determining a slip limit value for a wheel of a vehicle. The slip limit value is used for controlling the operation of the vehicle. The method comprises setting the slip limit value to be smaller than a high slip limit value for a majority of an operating time of the vehicle. The method also determines whether or not the vehicle assumes an infrequent manoeuvre condition in which the vehicle carries out an infrequent manoeuvre and/or or is predicted to carry out an infrequent manoeuvre within a predetermined time range, and in response to determining that the vehicle assumes the infrequent manoeuvre condition, setting the slip limit value to the high slip limit value.

摘要： A computer-implemented method for reducing a lateral drift of a heavy-duty vehicle due to a road bank angle, where the heavy-duty vehicle is associated with a non-zero understeer/oversteer gradient. The method comprises obtaining a road bank angle of a road section the heavy-duty vehicle is about to traverse; obtaining a vehicle model indicative of a vehicle motion response to the road bank angle, where the vehicle model includes the understeer/oversteer gradient; determining, based on the road bank angle and the vehicle model, a first compensation torque for reducing the lateral drift of the heavy-duty vehicle at the road section; and applying the first compensation torque across different wheels of the heavy-duty vehicle to reduce the lateral drift of the heavy-duty vehicle due to the road bank angle.
