  • Publication number: 20140041627
    Abstract: An electronic control unit (100), which serves as a control device for an internal combustion engine, executes feedback control for controlling the torque of an internal combustion engine (10) so as to coincide the rate of decrease in engine rotational speed with a target rate of decrease in the engine rotational speed. The electronic control unit (100) calculates a required torque that is a torque required to keep the engine rotational speed at a constant rotational speed, and increases a feedback gain in the feedback control as the calculated required torque increases.

  • Patent number: 8525463
    Abstract: A malfunction determination device for a motor control system, outputs a position signal that indicates a moved position of a movable member of a motor and a direction signal that indicates a movement direction of the movable member. The malfunction determination device determines a malfunction has occurred if a relationship between the position signal and the direction signal differs from that when the motor control system is operating normally. The malfunction determination device outputs a pulse signal that varies periodically along with variations in the moved position of the movable member as the position signal; outputs a periodic pulse signal in the same phase with the position signal as the direction signal if the movable member is moving in one direction; and outputs a periodic pulse signal in an opposite phase to the position signal as the direction signal if the movable member is moving in the other direction.

  • Publication number: 20130170953
    Abstract: A vehicular power transmitting system including an oil pump constructed to sufficiently reduce a required drive torque. A high-pressure-port discharge amount of first and second high-pressure passages of the oil pump is determined such that an amount of consumption of working oil of relatively high pressure can be afforded only by the high-pressure-port discharge amount, during steady-state running of a vehicle in which engine speed is not lower than a predetermined threshold value corresponding to a predetermined lowest target input shaft speed of a continuously variable transmission for its shifting control. The pressure of the working oil discharged from first and second low-pressure discharge passages is kept at a predetermined low level, and the required drive torque of the oil pump is sufficiently reduced.

  • Publication number: 20130089453
    Abstract: An oil pump includes a first spill passage formed on a side surface (60) of a pump chamber (58) to communicate a hydraulic pressure chamber (54) with a first high pressure discharge passage (68) when the entire hydraulic pressure chamber (54) is positioned between the first high pressure discharge passage (68) and a first low pressure discharge passage (70). Therefore, when the hydraulic pressure chamber (54) passes between the first high pressure discharge passage (68) and the first low pressure discharge passage (70), the hydraulic pressure inside the predetermined hydraulic pressure chamber (54) escapes to the first high pressure discharge passage (68) through a first spill passage (76), so a hydraulic pressure value inside the hydraulic pressure chamber (54) is maintained at the pressure value inside the first high pressure discharge passage (68).
