    摘要： In an automatic transmission with a speed changer having a plurality of engagement elements and configured to shift the speed changer into a selected one of a plurality of shift stages by switching engaged and disengaged states of the engagement elements, a first rotation sensor is provided for detecting input rotation of the speed changer and a second rotation sensor for detecting output rotation of the speed changer. Also provided is a transmission controller configured to determine whether a change in input torque inputted into the speed changer occurs. The transmission controller is further configured to determine that interlock has occurred in the speed changer, when there is no pulse signal output from the second rotation sensor though, during a vehicle stopped state, the input-torque change has occurred and the pulse signal from the first rotation sensor has been outputted.

    摘要： A continuously variable transmission (4) includes a variator (20) capable of varying a speed ratio continuously, and a subtransmission mechanism (30) provided in series with the variator (20). On the basis of an operating condition of a vehicle, a transmission controller (12) sets a destination through speed ratio (DRatio), which is an overall speed ratio of the variator (20) and the subtransmission mechanism (30) to be realized in accordance with the operating condition, and controls the variator (20) and the subtransmission mechanism (30) on the basis thereof. When shifts are prohibited in the subtransmission mechanism (30), the destination through speed ratio (DRatio) is limited to a speed ratio range that can be realized only by a shift in the variator (20).

    摘要： When a through speed ratio, which is an overall speed ratio of a variator (20) and a subtransmission mechanism (30), varies from a larger speed ratio than a mode switch speed ratio to a smaller speed ratio than the mode switch speed ratio, a gear position of the subtransmission mechanism (30) is changed from a first gear position to a second gear position. The mode switch speed ratio is set at a through speed ratio obtained when the speed ratio of the variator (20) is a Highest speed ratio and the gear position of the subtransmission mechanism (30) is the first gear position.

    摘要： A control apparatus for a continuously variable transmission for use with a vehicle is provided for permitting a driver to select one from three transmission modes for the continuously variable transmission, and providing an appropriate transmission ratio in accordance with a particular operating condition of a vehicle without causing an insufficient engine torque or over-revolution, particularly when the transmission is switched from a continuously variable transmission mode to a stepped manual transmission mode. The control apparatus comprises an ECU and an MT switch. The ECU executes a continuous automatic transmission mode for continuously setting a transmission ratio of the continuously variable transmission in accordance with a detected operating condition of the vehicle. The ECU also executes a stepped automatic transmission mode for setting the transmission ratio of the continuously variable transmission to one of a plurality of predetermined transmission stages in accordance with the detected operating condition of the vehicle. The CPU further executes a stepped manual transmission mode for setting the transmission ratio to one of a plurality of predetermined transmission stages in accordance with a driver's intention of transmission. The ECU sets the continuously variable transmission to one of the continuous automatic transmission mode, the stepped automatic transmission mode and the stepped manual transmission mode in accordance with a manipulating state of an MT switch.
