Patent ID: 8478495

Claim:
A shift control device, implemented on a computer processor, for a continuously variable transmission, the shift control device comprising: requested power calculating means that obtains a requested power, for making an actual vehicle speed reach a target vehicle speed set during a cruise control, on a basis of a speed difference between the target vehicle speed and the actual vehicle speed; requested torque calculating means that obtains a requested torque on a basis of the requested power and an engine rotation speed; accelerator-opening calculating means that obtains a cruise-control accelerator opening on a basis of the requested torque and the engine rotation speed; and shift controlling means that performs shift control by setting a target gear shift ratio of the continuously variable transmission on a basis of the cruise-control accelerator opening obtained by the accelerator-opening calculating means and the actual vehicle speed, wherein the accelerator-opening calculating means comprises a map for designating the cruise-control accelerator opening on the basis of the requested torque and the engine rotation speed, and wherein the map stores a cruise-control accelerator-opening characteristic curve set basically along an equal power line.
