  • Patent number: 11920674
    Abstract: In this shift device, in a case in which an external force has acted on a lever when an operating mechanism is causing the lever to pivot, a clutch mechanism permits rotation of a first detent plate with respect to a second detent plate, such that pivoting of the lever is permitted. Note that a restraining mechanism urges the lever toward a shift position. This enables to the restraining mechanism to urge the lever separately to the clutch mechanism, thereby enabling the degrees of freedom for setting a biasing load on the lever by the restraining mechanism to be increased.

  • Publication number: 20210207552
    Abstract: A pump control unit controls a fuel pump based on a control target value of an engine. A pump characteristic detection unit acquires a pump characteristic value among pump characteristic values, which indicate an operating state of a fuel pump and include a supplied current to the fuel pump, an applied voltage to the fuel pump, a generated voltage of the fuel pump, and a rotation speed of the fuel pump. A pump characteristic storage unit stores the acquired pump characteristic value together with the control target value. A determination threshold set unit sets a determination threshold value by using at least one of the stored pump characteristic value, the control target value, and a combination of at least two of the control target values. A fuel pump deterioration determination unit determines deterioration of the fuel pump by using the stored pump characteristic value and the determination threshold value.
