Abstract:
1. A system for controlling a vehicle that includes an engine, comprising: a controller having an input for receiving an engine torque input command indicative of a desired amount of torque to be generated by the engine, and an output for providing an engine torque output command to the engine; and a torque sensor operatively connected to the engine and the controller, the torque sensor adapted to measure torque output of the engine and to transmit a signal indicative of the measured torque to the controller; wherein the controller is configured to adjust the engine torque output command provided to the engine using torque feedback control based on the signal received from the torque sensor; and wherein the controller stores measured engine torque measurements in a matrix for correlation with at least one vehicle operating parameter and updates the stored engine torque measurements.
