Method and arrangement for controlling actual torque in a driveline of a land-based motor vehicle. Taking a direct, non-predictive measure of actual torque induced in the driveline of the motor vehicle and ascertaining a magnitude thereof. Ascertaining a magnitude of a torque demand being requested to be instituted in the driveline. Comparing the ascertained magnitude of the direct, non-predictive measure of actual torque taken is compared with a driveline-configuration dependent maximum torque threshold; in this way, an over-threshold torque condition is ascertained in the driveline based thereupon if such a condition exists. In multi-geared transmissions, the variability can be accounted for through the engagement of different ratio gears. In the event that such an over-threshold torque condition is detected, at least one of several possible over-threshold torque compensating effects will be applied to reduce or diminish the excessive portion of the torque. The remedial measure may be chosen from several possibilities including reconfiguring the variable ratio transmission and / or reducing powerplant-induced driveline torque.
