Abstract
A stepless transmissionis provided for preventing drive wheels from being driven despite the driver's intention during vehicle deceleration. A control device: when the required drive force of the vehicle is 0, controls the output rotational speed Ne of a travel drive sourceto be Ne, and controls the transmission gear ratio i of the transmissionso that the transmissionin the case where the Ne is Nechanges from a first state to a second state; and when the vehicle speed V is less than a boundary speed Vgn, controls the ratio i to be a state maintaining transmission gear ratio ign that enables the first state to be maintained even during vehicle deceleration. In the second state a rotational drive force is transmitted from an input shaftto an output shaft. In the first state the transmission is prevented.
