ABSTRACT:
A speed change control device carries out speed change control of a stepless speed change mechanism in accordance with the vehicle speed. The speed change control device includes: first vehicle speed selection means for comparing a first vehicle speed obtained from the rotation speed of an output member26of the stepless speed change mechanism and a second vehicle speed obtained from the rotation speed of the wheels and for selecting the lower of the first and second vehicle speeds as the substitute vehicle speed; and second vehicle speed selection means for comparing the third vehicle speed obtained from the output side rotation speed of a clutch mechanism and the substitute vehicle speed, and for selecting the higher of the third vehicle speed and the substitute vehicle speed as the control vehicle speed. The control vehicle speed is used as the vehicle speed V for carrying out speed change control.
