Patent ID: 6889132

Claim:
A method of controlling a vehicle drive having a 4Ã—4 mode of operation and other modes of operation using an electronic control system providing a torque output in response to driver demand, comprising: controlling torque output of one of an engine and transmission of said vehicle when the vehicle is in the 4Ã—4 mode using a calibration table stored in system memory and indicating a relationship of torque output as a function of accelerator pedal position and a speed parameter for reducing sensitivity of the torque output to accelerator pedal position in the 4Ã—4 mode of operation, and controlling torque output of one of the engine and the transmission of said vehicle when said vehicle is in one of the other modes of operation using a different calibration table stored in system memory and indicating a different relationship of torque output as a function of the accelerator pedal position and the speed parameter.
