Abstract
A control apparatus for a drive-force transmitting apparatus that includes a transmission having primary and secondary pulleys. The control apparatus calculates a target thrust applied to the secondary pulley such that the target thrust is larger during a vehicle driven state than during a vehicle driving state. The control apparatus sets a first determination threshold of a drive-force related value used to determine whether it is the vehicle driving state or vehicle driven state and a second determination threshold of the drive-force related value used to switch from determination of the driven state to determination of the driving state, such that a difference of the first and second determination thresholds is larger and a range of the drive-force related value in which the driven state is determined is wider, when an automatic running-speed control is executed, than when the automatic running-speed control is not executed.
