  • Patent number: 10100925
    Abstract: After engagement of a clutch is suppressed from being started and a rotational speed of an input shaft of an automatic transmission is suppressed from being increased due to an increase in rotation resistance of the input shaft of the automatic transmission, which occurs by half-engagement of a clutch, the clutch is disengaged, and the clutch is completely engaged. In this way, the clutch is completely engaged after the rotational speed of the input shaft is suppressed from being increased. Thus, a heat generation amount of the clutch can be reduced, and furthermore, durability of the clutch can be improved by a reduction in the heat generation amount.
    Type: Grant

  • Patent number: 9033852
    Abstract: In hydraulic control, an electronic control unit controls controlled hydraulic pressure of a control valve in order to control a hydraulic oil amount in a torque converter and a hydraulic oil pressure of a forward-reverse travel switching mechanism, and the electronic control unit increases the controlled hydraulic pressure when the hydraulic oil amount in the torque converter is insufficient at an engine start or immediately after the engine start in comparison with a case where the hydraulic oil amount in the torque converter is sufficient. The hydraulic control device includes: the torque converter; the forward-reverse travel switching mechanism; the control valve configured to change the hydraulic oil amount in the torque converter and the hydraulic oil pressure of the forward-reverse travel switching mechanism by changing the single controlled hydraulic pressure; and electronic control unit.
