Abstract:
A vehicle driveline torque managing process provides a motor driven actuator that manages clamping forces exerted on a clutch pack and regulates a coupling of power between a driveshaft and one of the axles of a vehicle, based on clutch positions. The process derives coupling torque values by stepping a motor from a maximum clutch separation position through a series of clutch positions while recording a motor driven commanded torque value at each step, up to a maximum clutch compression position having a maximum commanded motor torque value. Then, each motor driven commanded torque value is converted into respective clutch force values as a function of clutch position, thereby relating each clutch torque to a clutch position based on conversion tables stored in a controller that are associated with physical factors that influence clutch torque for each of the respective clutch actuator positions.
