  • Continuously variable transmission and method for controlling the same
    Patent number: 10228055
    Abstract: A transmission controller increases hydraulic pressure supplied to a secondary pulley and decreases hydraulic pressure supplied to a primary pulley to shift a variator to a mechanical Low speed ratio when the hydraulic pressure supplied to the primary pulley and the secondary pulley vibrates. The transmission controller shifts the variator from the mechanical Low speed ratio to a High side when a sub-transmission mechanism is downshifted during controlling a speed ratio of the variator at the mechanical Low speed ratio.
    Type: Grant
    Filed: June 3, 2015
    Date of Patent: March 12, 2019

  • Continuously variable transmission and method for controlling the same
    Patent number: 9964207
    Abstract: A transmission controller increases hydraulic pressure supplied to a secondary pulley and decreases hydraulic pressure supplied to a primary pulley to shift a variator to a mechanical Low speed ratio during the hydraulic pressure supplied to the primary pulley and the secondary pulley vibrates. The mechanical Low speed ratio is a speed ratio where a groove width of the primary pulley has a maximum value possible to be employed in structure of the primary pulley.
