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 power transmission system is provided. The control apparatus includes an electronic control unit. The electronic control unit is configured to, when a discharge flow rate of a mechanical oil pump is smaller than a predetermined flow rate and an electric oil pump is being driven while a vehicle is traveling, determine whether a decrease in the operating hydraulic pressure has occurred. The electronic control unit is configured to, when a first engagement device is controlled from a released state toward an engaged state, control a first control pressure such that the first control pressure in a case where a decrease in a operating hydraulic pressure has occurred is lower than the first control pressure in a case where a decrease in the operating hydraulic pressure does not occur.

Abstract: A control system and a control method for a vehicle, the vehicle includes an engine, an input shaft, an output shaft, a continuously variable transmission section, a stepped transmission section and a clutch mechanism, and a control device. The continuously variable transmission section and the stepped transmission section are provided between the input shaft and the output shaft. The clutch mechanism is provided in a torque transmission path between the stepped transmission section and drive wheels. The control device is configured to disengage the clutch mechanism in a case where a vehicle speed is at least equal to a specified value and the engine is stopped.

Abstract: A hydraulic control system for a vehicle having a continuously variable transmission in which a torque transmitting capacity thereof is changed hydraulically, and an engagement device which is connected to the continuously variable transmission in series and in which a torque transmitting capacity thereof is changed hydraulically. The hydraulic control system comprises a selecting means that selects a command pattern for setting an engagement pressure of the engagement device out of a plurality of patterns when an initial pressure is lower than a steady pressure for a normal running of the vehicle. The selecting means is configured to select the command pattern in such a manner that the torque transmitting capacity of the engagement device does not exceeds the torque transmitting capacity of the continuously variable transmission, based on at least any of conditions of the initial pressure that is lowered to be lower than the steady pressure, and a rotational speed of the continuously variable transmission.
