We developed a new automatic transmission control system that performs shift control for the automatic transmission (A/T) using the road data obtained from the navigation system, which previously had been used only for route guidance, and installed it in a new car, Progrès. This system reads the distance to the approaching corner and its shape based on the vehicle's position data and the data of the approaching road obtained from the navigation system, and determines the optimum gear based on these data and the current vehicle speed to perform optimum shift control in linkage with the driver's driving operation. In this paper, configuration, features and effects of this new A/T control system that takes consideration of navigation data are described.
