Abstract
A method of controlling an automatic transmission of a motor vehicle operating in a automatic speed control speed mode is provided. The first step in the method is measuring 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 the engine is then predicted. A torque output of the transmission in a second gear is then determined based upon the predicted maximum torque capable of being produced by the engine. A transmission shift from the first gear to the second gear is then allowed if the determined torque output of the transmission in the second gear is greater than the torque load of the transmission in a first gear.
