  • Patent number: 6634982
    Abstract: An automatic transmission control apparatus includes a continuously variable transmission (CVT) which, in turn, includes a primary pulley, a secondary pulley, a belt stretched between the primary pulley and the secondary pulley. The control apparatus further includes a pinching pressure generator for generating a pinching pressure on the belt, a travel environment all detector for detecting the travel environment of a vehicle, a torque variation estimator for estimating the transmission torque variation during travel, and a pinching pressure changer for changing the pinching pressure based on the estimation. The pinching pressure is prevented from constantly increasing because the transmission torque variation during travel is estimated, and the pinching pressure for the belt is changed based on the estimation. Accordingly, the torque transmission efficiency can be increased, and the fuel efficiency can thus be improved.

  • Patent number: 6198242
    Abstract: The present powered sliding device comprises a wire drum, a motor for rotating the drum, and a clutch means provided between the drum and the motor. The clutch means has a coupled state for rotating the drum, an uncoupled state, and a brake state. The clutch means is displaced from the coupled state to the brake state when the wire drum is rotated at an over speed. The clutch means in the brake state transmits the over speed rotation of the wire drum to the motor.
