Title:
TRANSMISSION CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/074009
Kind Code:
A1
Abstract:
A transmission control device according to the present invention controls a stepless transmission installed in a vehicle. The device has, as modes for the stepless transmission, a stepless transmission mode M1 in which the transmission gear ratio is changed in a stepless manner on the basis of the driving state of the vehicle, and a stepped transmission mode M2 in which the transmission ratio is changed in a stepped manner on the basis of the driving state of the vehicle. The device comprises a transmission mode switching controller 12 that controls the switching of the stepless transmission mode M1 and the stepped transmission mode M2 on the basis of the actual accelerator position. If the actual accelerator position has reached or exceeded a first threshold T1 set so as to increase in stages in accordance with an increase in vehicle speed, the transmission mode switching controller 12 switches from the stepless transmission mode M1 to the stepped transmission mode M2.
