Abstract:
1. A computer-based method for generating a torque map operating an all-wheel drive system (“AWD”) of a vehicle, the method comprising the steps of: generating a model describing how an all-wheel drive (“AWD”) electronic control unit (“ECU”) included in the vehicle processes data received from one or more vehicle subsystems; executing the model on a computing device coupled to the vehicle to emulate operation of the AWD ECU using the computing device; capturing data from a controller area network (“CAN”) included in the vehicle; capturing data describing wheel torque from one or more wheels of the vehicle; generating a raw torque value using the data from the CAN and the data describing wheel torque using the executed model; filtering the raw torque value to generate a torque value associated with an engine speed and with an intake air pressure from the data captured from the CAN; and storing the torque value and associated engine speed and intake air pressure in a computer readable storage medium included in the computing device executing the model.
