Title:
CONTROL DEVICE AND CONTROL METHOD FOR CONTINUOUSLY VARIABLE TRANSMISSION MECHANISM FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2017/043458
Kind Code:
A1
Abstract:
The present invention is provided with: an auxiliary transmission mechanism (30) which is arranged in series with a variator (20), and which comprises at least a second forward speed gear; and a transmission controller (12) which, when at least the accelerator pedal opening (APO) reaches zero and until braking power is generated by pressing on the brake pedal, increases the belt capacity to be larger than the belt capacity set for when the accelerator pedal opening (APO) is zero. The more the transmission ratio of the auxiliary transmission mechanism (30) is on the high transmission ratio-side, the smaller the transmission controller (12) makes the size of the increase with respect to the belt capacity set for when the accelerator pedal opening (APO) is zero.
