Patent ID: 8321115

Claim:
A method for using a rotational torque of a vehicle drive shaft coupled to a driven wheel together with a wheel speed of a non-driven wheel for a vehicle throttle control system, the method comprising: reading first and second torque values generated by a torque sensor; identifying that a sustained drop has occurred between the first and the second torque values for a period of time within the range of substantially 3 ms to 100 ms; determining if a change occurred between the first and second torque value readings in any of: a throttle position; a gear setting; and a brake pressure; signaling a detected traction loss when the sustained drop occurred with no change, between the first and second torque value readings, in any of the throttle position, the gear setting, and the brake pressure; calculating a desired throttle value using an engine torque and a target engine speed operable to prevent wheel slip of the driven wheel; and sending a throttle command signal operable to change an existing throttle value to the desired throttle value.
