Abstract
Provided are a variator and a transmission controller in an engine-driven vehicle. The transmission controller has an instantaneous interruption recovery control portion configured to, upon a power reset from an instantaneous interruption during running, set a target through transmission ratio and a desired through transmission ratio to a lowest transmission ratio value by initialization and perform recovery control to recover an actual through transmission ratio of the variator to a transmission ratio value for shifting to normal control. The instantaneous interruption recovery control portion is further configured to, upon the power reset from the instantaneous interruption during the running, set a change speed of the target through transmission ratio from the lowest transmission ratio value to the desired through transmission ratio, to be higher than that under the normal control, before a time at which the desired through transmission ratio value deviates from the lowest transmission ratio value.
