Abstract
An ECU executes a program that includes a step of increasing belt squeezing pressure to a value P (ON) greater than a normal value P (OFF) that is set as the belt squeezing pressure when a footbrake switch is off, when the footbrake switch is on and the time elapsed after the footbrake switch was turned on is less than a threshold value T (); and a step of gradually reducing the belt squeezing pressure to the normal value P (OFF) when the time elapsed after the footbrake switch was turned on is equal to or greater than the threshold value. As a result, a decrease in fuel efficiency of a vehicle in which a continuously variable transmission is mounted, as well as a reduction in the durability of a belt of this continuously variable transmission, can be reduced.
