摘要： A vehicle driving apparatus configured with a drive power source, a fluid coupling, a transmission apparatus; and a control apparatus. A rotation of a drive input member driven by the drive power source is transmitted to a shift input member via the fluid coupling and a rotation of the shift input member is shifted by the transmission apparatus and then transmitted to an output member. When a state shift command for shifting from a non-transmission state to a transmission state is input into a control apparatus in a state in which the drive power source does not generate a driving force, the control apparatus performs a shift input rotation operation before engaging a frictional engagement element and shifting to the transmission state by causing the drive power source to generate the driving force and rotating the shift input member via the fluid coupling while maintaining the non-transmission state.

摘要： An exemplary control device includes an input torque detection unit that detects an input torque input to the input shaft; and a controller that: determines torque distribution of two of the friction engagement elements that form the shift speeds; and calculates a transmission torque of the two friction engagement elements based on the input torque and the torque distribution and sets the engagement pressure to obtain a torque capacity that can transmit the transmission torque, wherein the controller sets the engagement pressure such that slippage does not occur in the two friction engagement elements in a state where engagement of the two friction engagement elements forms the shift speeds and such that, even if an additional friction engagement element engages based on the line pressure while the two friction engagement elements are engaged, one of the three friction engagement elements is caused to slip.

摘要： In an operation of controlling an automatic transmission, an engagement pressure for each hydraulic servo in a normal operation is determined so that none of friction engagement elements slips at each shift speed in the normal operation, and so that in case of a failure in which the friction engagement element that is supposed to be disengaged in the normal operation is engaged, one of the friction engagement elements slips, and thus one of the shift speeds is established. In the control operation, upon detection of a failure state in which a gear ratio after a shift operation is a gear ratio of a shift speed different from a shift speed to be established, the slipping friction engagement element is disengaged, and the shift speed that is different from the shift speed to be established is temporarily retained.
