A driving assist method and a driving assist device is provided for controlling a transmission ratio of a continuously variable transmission, which steplessly shifts gears and outputs an engine rotation speed. The driving assist method and a driving assist device continuously performs downshifting until an upshift occurs, when the transmission ratio of the continuously variable transmission is controlled so that the engine rotational speed increases in conjunction with an increase in a vehicle speed and the upshift will be performed after the vehicle has accelerated.
