1. A method for controlling motion by a heavy-duty vehicle, wherein the vehicle is arranged to be controlled based on a target longitudinal wheel slip of at least one driven wheel on the vehicle, the method comprising monitoring an acceleration of the vehicle,
monitoring a current longitudinal wheel slip of the at least one driven wheel,
reducing the target longitudinal wheel slip of the at least one driven wheel when the monitored acceleration of the vehicle decreases while the monitored current longitudinal wheel slip is non-decreasing, and
controlling wheel slip of the at least one driven wheel based on the target longitudinal wheel slip.
