  • Publication number: 20120059559
    Abstract: The shift control unit executes a control to cause the through speed ratio to follow the final through speed ratio by changing only the speed ratio of the variator if a shift instruction is given from the driver a plurality of times in a row when the manual mode is selected, and advances the start of a change in the speed ratio of the sub-transmission mechanism or accelerates the progression of the change of the speed ratio as compared with the case where the manual mode is not selected when the speed ratio of the variator is maximized or minimized and the through speed ratio cannot follow the final through speed ratio.

  • Publication number: 20120059556
    Abstract: The shift control unit shifts the sub-transmission mechanism while changing the speed ratio of the variator in response to a change in the speed ratio of the sub-transmission mechanism so that the through speed ratio does not change after the through speed ratio is caused to reach the final through speed ratio by changing only the speed ratio of the variator if the speed ratio corresponding to the shift instruction from the driver is between a first speed ratio at which the sub-transmission mechanism is in the second gear position at the high speed side and the speed ratio of the variator is lowest and a second speed ratio at which the sub-transmission mechanism is in the first gear position at the low speed side and the speed ratio of the variator is highest when the manual mode is selected.

  • Publication number: 20120059558
    Abstract: In a manual mode, a gear position of a continuously variable transmission is selected based on an input operation from a driver, a final through speed ratio is set based on the selected gear position and a variator and a sub-transmission mechanism are controlled to realize the final through speed ratio. Whether an input torque to the sub-transmission mechanism is positive or negative is determined based on an input torque to the sub-transmission mechanism when the manual mode is selected.

  • Publication number: 20110053718
    Abstract: An inertia torque input into the continuously variable speed change mechanism from the subtransmission mechanism is estimated during the shift in the subtransmission mechanism. During the shift in the subtransmission mechanism, a required oil pressure, which is an oil pressure required to maintain a contact frictional force between the respective pulleys and the wrapped member, is calculated on the basis of an input torque into the continuously variable speed change mechanism and the inertia torque.

  • Publication number: 20080252438
    Abstract: A warning system has a power position detection device, a gear shift position detection device, an alighting detection device, and a power position warning device. The device is operable to provide the power position warning indication when the power position detection device, the gear shift position detection device and the alighting detection device detect that there are preparations for alighting, that the gear shift position is in a P (Park) range and that the power position is in a position other than showing IGNITION OFF. In another aspect, the invention provides a gear shift position warning device. The power position warning device outputs a power position warning indication when the gear shift position detection device detects that the gear shift position has moved to the P range during output of the gear shift position warning indication.
