<p>The temperature of transmission fluid in a vehicle automatic transmission is sensed directly or indirectly S1 and when this temperature is above a predetermined value S2, or alternatively, a predicted future value is above a predetermined value, torque reduction means connected to the vehicle engine control system causes the engine output torque to be reduced S3, S4. Torque reduction may be by throttle, air/fuel ratio, or ignition timing control and on the basis of a map in the control system memory S3. Additionally, the top gear of the transmission may be inhibited S5 and, if the vehicle speed is above a predetermined value S6, torque converter lock-up may be engaged S7. A warning light for the driver may be lit S8.</p> |
