摘要：A method of controlling an automatic transmission of a motor vehicle operatingin a automatic speed control speed mode is provided. The first step in the method ismeasuring the torque output of the engine. A torque load acting on the transmission in a

first gear is then determined. A maximum torque capable of being produced by theengine is then predicted. A torque output of the transmission in a second gear is thendetermined based upon the predicted maximum torque capable of being produced bythe engine. A transmission shift from the first gear to the second gear is then allowed ifthe determined torque output of the transmission in the second gear is greater than thetorque load of the transmission in a first gear.
