  • Patent number: 11052904
    Abstract: When starting a skip downshift, a controller for an automatic transmission disengages two or more engagement elements that are in an engaged state. The disengaging two or more engagement elements includes setting a first engagement element, which is one of the two or more engagement elements that are disengaged and is used to form an intermediate gear stage having a lower transmission ratio than a post-shifting gear stage, to an engagement preparation state that maintains a state immediately before the engaged state. Subsequently, the controller engages a second engagement element, which is used to form both the intermediate gear stage and the post-shifting gear stage, and temporarily increases engagement pressure of the first engagement element. The controller disengages the first engagement element and engages a third engagement element, which is used to form the post-shifting gear stage, to form the post-shifting gear stage.

  • Patent number: 10808835
    Abstract: A shift control device of a vehicle including an internal combustion engine and a multi-speed transmission in series, the shift control device comprises: a control portion providing a downshift control in which an input shaft rotation speed of the multi-speed transmission is increased through a torque-up of the internal combustion engine toward a post-shift input shaft rotation speed in a neutral state where a release-side engagement device to be released during a downshift of the multi-speed transmission is released, so as to engage an engagement-side engagement device to be engaged after the shift. In the case of a shift pattern having a large internal inertia of the multi-speed transmission, the control portion controls a torque capacity of the engagement-side engagement device to a value greater than zero before starting a torque-up control of the internal combustion engine.

  • Patent number: 7599767
    Abstract: When both engines operate properly, a control apparatus for an aircraft performs control of thrust and attitude of an aircraft using an output that is produced evenly by the two engines. When a failure occurs in one of the two engines, the control apparatus performs the control of thrust and attitude of the aircraft by increasing an output of the remaining engine that operates properly to an emergency output. When the failure occurs in one of the two engines, the control apparatus makes an engine output that is used for the control of thrust and attitude of the aircraft lower than an engine output that is used when both engines operate properly, until the remaining engine that operates properly is enabled to produce the emergency output.

  • Publication number: 20090113896
    Abstract: There is provided a control apparatus for a gas-turbine engine which is configured in such a manner that a portion of compressed air from a compressor is supplied to a combustion chamber and the other portion of the compressed air is sent to the outside of the engine to be used as source of energy, and a turbine is rotated by combustion gas produced in the combustion chamber. The control apparatus executes the optimum combustion control in an extraction engine. The control apparatus calculates the physical quantity related to the air in the gas-turbine engine using the turbine flow-rate coefficient in the range in which the turbine chokes.

  • Patent number: 6837225
    Abstract: In a fuel supply control device for a turbo-charged diesel aircraft engine, a fuel injection amount is reduced in accordance with the air temperature when the flight altitude of the aircraft is higher than a predetermined altitude. The turbocharger speed increases as the flight altitude or the air temperature becomes higher even if the engine output power is the same. Therefore, if the maximum engine output power is restricted based only on the flight altitude in order to prevent the overrun of the turbocharger, an undue restriction on the maximum output power may occur when the air temperature changes. By controlling the fuel injection amount based on both air temperature and the altitude, i.e., by reducing the fuel injection amount in accordance with the air temperature when the altitude is higher than a predetermined altitude, an undue restriction of the engine output power, as well as an over-speed of the turbocharger, can be prevented.
