Abstract: A control apparatus for a vehicular drive unit is provided. The vehicular drive unit includes a continuously variable transmission, and a clutch. The control apparatus includes an electronic control unit that is configured to acquire an oil temperature of hydraulic oil for controlling the continuously variable transmission and the clutch, and control the clutch such that a torque capacity of the clutch becomes smaller than a torque capacity that is set in a case where an oil temperature of the hydraulic oil is higher than a predetermined oil temperature, when the oil temperature is equal to or lower than the predetermined oil temperature, or control the continuously variable transmission such that a speed ratio of the continuously variable transmission becomes equal to or larger than a lower limit set in advance when the oil temperature of the hydraulic oil is equal to or lower than the predetermined oil temperature.

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.
