Abstract
A variable transmission system includes a continuously variable transmission, a shiftable sub-transmission in series with an output of the continuously variable transmission, and controller. A sensor senses a position of a driver's shift lever, and another sensor senses a gear position of the shiftable sub-transmission. The sensors report to the controller. If both sensors detect reverse drive conditions, the controller adjusts an angle of a swash plate of the continuously variable transmission for the reverse driving direction. If only one of the sensors indicates a rear drive condition, the controller compares an engine speed to a threshold value. If the engine speed exceeds the threshold value, the controller curbs the engine speed by cutting off the ignition.
