TRANSMISSION CONTROL DEVICE AND TRANSMISSION CONTROL METHOD

WIPO Patent Application WO/2016/152290

A1

The present invention pertains to a transmission control device that is provided with a controller (12) and a hydraulic pressure control circuit (11). The controller (12) determines whether a rotation sensor (42) has failed. The controller (12) and the hydraulic pressure control circuit (11) variably control the gear ratio of a variator (20) and variably control the gear speed of an auxiliary transmission mechanism (30). If it is determined that a failure has occurred, the controller (12) and the hydraulic pressure control circuit (11) fix the gear speed of the auxiliary transmission mechanism (30) at a first speed. If the gear speed of the auxiliary transmission mechanism (30) is a second speed when it is determined that a failure has occurred, the controller (12) and the hydraulic pressure control circuit (11) fix the gear speed of the auxiliary transmission mechanism (30) at the first speed when the vehicle is stopped.
