  • Patent number: 10801234
    Abstract: A locking device for a trunk in a vehicle. The locking device includes a latch configured to change a state of the trunk between locked and unlocked, and a lever configured to drive the latch to an open position. The locking device further includes a lock knob configured to be disposed outward of a vehicle body to visually determine from an outside of the vehicle whether the trunk is in the locked state or the unlocked state. The lock knob is further configured to be selectively placed in a locked position. In the locked position, the trunk is configured to be brought into the locked state by prohibiting the latch from being driven to an open position.

  • Patent number: 9822726
    Abstract: In a fuel injection controller, a first throttle opening TH0 is defined at a specific time P2. The P2 is a specific time later than the peak value of an intake pipe internal pressure PB of a previous cycle. In the cycle, P3 is a specific time that is set immediately before the calculation of the injection time. A second throttle opening TH2 is defined at P3. The fuel injection controller corrects a fuel injection amount based on variation in correction time ta0 at the first throttle opening TH0 to correction time ta1 at the second throttle opening TH1. The time P2 is later than time P1, which is the peak value of the intake pipe internal pressure of the previous cycle. Accordingly, the fuel injection amount correction is completely unaffected or only slightly affected by the intake pipe internal pressure, thus ensuring close-to-ideal correction.

  • Patent number: 8751121
    Abstract: Shift controlling apparatus for a vehicle which automatically carries out changeover between a plurality of shift gear stages based on an automatic shift map including a drive mode shift map and a sport mode shift map having an increased region in which a speed change ratio is low compared to the drive mode shift map and corresponds to more sporty operation than that of the drive mode shift map. The drive mode shift map has a first mode portion and a second mode portion having an increased region in which the change gear ratio is low compared to the first mode portion, but smaller than the increased region of the sport mode shift map. Changeover between the first and second mode portions is carried out based on an acceleration history in accordance with a throttle opening of the vehicle.

  • Patent number: 8353185
    Abstract: In a vehicle handle locking apparatus, a locking member that can operate between a locked position and an unlocked position and a holding member that operates together with the locking member are resiliently urged toward the unlocked position side; and an engaging member that engages with a holding member in the locked position and holds the locking member in the locked position is operated by operation of an electric actuator toward the side to release the engagement with the holding member. Forced unlocking drive device forcibly drives the holding member toward the unlocked position side in response to the operation of the electric actuator in a state in which the locking member is in the locked position. Accordingly, it is possible to provide a vehicle handle locking apparatus that releases, even when a force in a rotating direction is applied to a steering handle, engagement of a locking member with the steering handle or a linkage member so that an unlocked state is reliably achieved.
