Abstract
A control system for a transmission, comprises a shift control function to output a shift instruction signal on the basis of a predetermined shift pattern and a road data detecting function to detect the road data of a route to be followed by a vehicle. This control system further comprises a start detecting function to detect the start of the vehicle; and a shift pattern control function to set a shift pattern for a curve, as having a control content for making it liable to set a larger gear ratio, as the shift pattern when the vehicle start is detected by the start detecting function and when a curved road is detected in the route to be followed, by the road data detecting function.
