Patent ID: 11015704

Abstract:
A vehicle has an engine (1) as a driving source. Output rotation of the engine (1) is transmitted to driving wheels (7) through a torque converter (2) equipped with a lock-up clutch, a first gear train (3), a transmission (4) formed by combination of a variator (20) and an auxiliary transmission (30), a second gear train (5) and a final speed reduction device (6). The second gear train (5) is provided with a parking mechanism (8) that mechanically locks an output shaft of the transmission (4) so that the output shaft of the transmission (4) cannot rotate during parking of the vehicle. A shift speed when down-shift is performed by the variator (20) during a torque-down request to the engine (1) is set to be slower than a shift speed when down-shift is performed by the variator (20) during a non-torque-down request.
