Shift control device for continuously variable transmission |
摘要 |
A requested cruise-control horsepower calculator obtains a requested cruise-control horsepower from a speed difference between a target cruising vehicle speed and an actual vehicle speed. A requested cruise-control torque calculator obtains a requested cruise-control torque on the basis of the requested cruise-control horsepower and an engine rotation speed. A cruise-control accelerator-opening calculator sets a cruise-control accelerator opening by referring to an engine torque map in which a cruise-control accelerator-opening characteristic curve is set along an equal horsepower line on the basis of the requested cruise-control torque and the engine rotation speed. A target primary rotation-speed calculator sets a target primary rotation speed by referring to a shift-line map on the basis of the cruise-control accelerator opening and the actual vehicle speed. A shift controller obtains a target gear shift ratio on the basis of the target primary rotation speed and the actual vehicle speed so as to perform shift control. |
