Device for controlling vehicular variator

A vehicular variator control device for controlling a variator of a vehicle, the variator being arranged between a running drive source and drive wheels to continuously vary a transmission ratio,

• the control device comprising a shift control unit configured to control an actual transmission ratio of the variator to a target transmission ratio,
• the shift control unit comprising:
• a desired transmission ratio setting portion configured to set a desired transmission ratio of the variator according to at least one of a driver's operating action and a running state of the vehicle;
• and
• a target transmission ratio setting portion configured to set the target transmission ratio so as to change the actual transmission ratio to the desired transmission ratio at a given shift speed,
• wherein the shift control unit further comprises an instantaneous interruption recovery control portion configured to, upon a power reset from an instantaneous interruption during running, set the target transmission ratio and the desired transmission ration to a lowest transmission ratio value by initialization and perform recovery control to recover the actual transmission ratio of the variator to a transmission ratio value for shifting to normal control, and
• wherein 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 transmission ratio from the lowest transmission ratio value to the desired target transmission ratio to be higher than that under the normal control before a time at which the desired transmission ratio deviates from the lowest target transmission ratio value.
