Patent ID: 7440832

Claim:
A method for controlling actual torque in a driveline of a land-based motor vehicle, the motor vehicle including a drivetrain having a powerplant interconnected with at least one ground engaging drive wheel via a driveline, the driveline including at least a variable ratio transmission, the method comprising the steps of: 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 with a driveline-configuration dependent maximum torque threshold and thereby ascertaining an over-threshold torque condition in the driveline based thereupon; and applying at least one over-threshold torque compensating effect chosen from the group comprising (a) reconfiguring the variable ratio transmission and (b) reducing powerplant-induced driveline torque.
