摘要： A method is provided for adaptively determining a torque-related (K-factor) value for a torque converter in a vehicle and providing adaptive torque management to an automatic transmission. The torque-related K-factor value is computed for a given torque converter as a function of engine speed and difference in torque measured with the vehicle operating in idle neutral and drive. The vehicle dynamically learns the K-factor value and manages torque applied to the transmission by limiting the engine output speed as a function of the learned torque-related K-factor and vehicle speed.

摘要： The present invention provides an apparatus for limiting the occurrence of knock conditions in an internal combustion engine. The apparatus includes a throttle sensor that detects transition of an engine throttle from a steady state throttle condition to a wide open throttle condition. Further, spark means is provided for generating a spark for an engine cylinder firing event, with the spark means generating the spark with an associated spark advance. Further, a controller is provided that is responsive to the wide open throttle condition detected by the throttle sensor and that causes the spark advance to incrementally advance to a maximum level over a predetermined time period, thereby minimizing the occurrence of engine knock conditions.
