Abstract:
A drive slip control system for a vehicle having a drive unit driving at least one driven wheel, the drive slip control system comprising:a drive slip controller, the drive slip controller configured to perform a drive slip control operation when a non-permitted slip occurs and when a spinning of a driven wheel occurs, the drive slip control operation including at least one of reducing a torque of the drive unit for the at least one driven wheel and applying a braking force at the spinning driven wheel, the drive slip controller configured to change a value of at least one parameter to render the drive slip controller less sensitive when a gearshift has been detected so that during the gearshift at least one of the following occurs: the drive slip controller does not react to non-permitted slip; the drive slip controller reacts later to non-permitted slip; reducing the amount by which the torque is lowered; and reducing the applied brake force.
