Abstract
A control system of an automatic transmission for a vehicle comprises a first detecting means for detecting an accelerator pedal opening angle, a second detecting means for detecting a vehicle speed, a calculating means for calculating a required horsepower value by reference to a map parameterizing the accelerator pedal opening angle and the vehicle speed and a judging means for judging a gear shift of the automatic transmission by reference to a shift map parameterizing the required horsepower value and the vehicle speed. The shift map is prepared based on a plurality of full throttle horsepower curves obtained per each gear position in relation to the vehicle speed.
