  • Patent number: 10450980
    Abstract: During a fuel cut-off control, if a vehicle deceleration rate becomes greater than a rapid deceleration determination value, which is calculated based on a rotational resistance of internal combustion engine 1, a vehicle is determined to be in a state of rapid deceleration. The rapid deceleration determination value is set to decrease as the rotational resistance of internal combustion engine 1 increases. The rotational resistance thereof increases as the vehicle speed decreases, and increases as a transmission gear ratio increases. Thereby, during decelerating on a high vehicle speed side, an erroneous determination of rapid deceleration due to a longitudinal vibration of the vehicle that occurs when the fuel cut-off control starts can be prevented, and during decelerating on a low vehicle speed side, a determination of rapid deceleration can be implemented to terminate the fuel cut-off control and thereby prevent the internal combustion engine 1 from being stopped.

  • Patent number: 10443551
    Abstract: A valve member is movable with first and second partition member and opens and closes a first pressure chamber with respect to a return passage.

The first, second, and third pressure chambers cause fuel from a fuel flow passage to flow therethrough. A switching unit switches an opening and closing state of the second pressure chamber and the third pressure chamber with respect to the fuel flow passage and the return passage.

  • Patent number: 10428755
    Abstract: An ECU calculates peak-current arrival time (time elapsed before a detected current arrives at a target peak current), and calculates predetermined-current arrival difference time (time elapsed before the detected current becomes lower than a predetermined current after exceeding the predetermined current). The ECU uses a beforehand stored relationship between the predetermined-current arrival difference time and defined peak-current arrival time to calculate the defined peak-current arrival time corresponding to the latest predetermined-current arrival difference time. The ECU uses such defined peak-current arrival time to compare the latest peak-current arrival time with the defined peak-current arrival time (for example, calculates a difference between the peak-current arrival time and the defined peak-current arrival time), and thus determines a shift in detected current of a current detection circuit.
