Abstract
A vehicle has an engine () as a driving source. Output rotation of the engine () is transmitted to driving wheels () through a torque converter () equipped with a lock-up clutch, a first gear train (), a transmission () formed by combination of a variator () and an auxiliary transmission (), a second gear train () and a final speed reduction device (). The second gear train () is provided with a parking mechanism () that mechanically locks an output shaft of the transmission () so that the output shaft of the transmission () cannot rotate during parking of the vehicle. A shift speed when down-shift is performed by the variator () during a torque-down request to the engine () is set to be slower than a shift speed when down-shift is performed by the variator () during a non-torque-down request.
