Title: Control system for continuously variable transmission of motorcycle

Abstract: A control system for a continuously variable transmission of a motorcycle, which is capable of improving the steerability of the motorcycle in a low-speed range of the motorcycle. The motorcycle includes a centrifugal clutch mechanism disposed between the transmission and a rear wheel, for connection and disconnection between an engine and the rear wheel. An ECU of the motorcycle stores an idle-up use transmission map and a warmed-up use transmission map, and carries out transmission control of the transmission based on the idle-up use transmission map at the start of the engine, and switches the idle-up use transmission map to the warmed-up use transmission map when at least one of a first condition that a predetermined time period preset based on the temperature of the engine has elapsed after the start of the engine and a second condition that rotational speed of the engine is lower than a predetermined idling engine speed is satisfied.
