  • Patent number: 11168784
    Abstract: A vehicle shifter device for ensuring high safety by suppressing misoperation by a driver. The vehicle shifter device includes a shift lever and a lock plate. The shift lever has a cylindrical lever body, a rod movable in an axial direction in a cylinder of the lever body, and a first lock lever and a second lock lever connected to the rod. The first lock lever is substantially L-shaped in plan view. The lock plate has a first extension portion extending in an X-direction and a second extension portion, integrally formed with the first extension portion, that extends in a Y-direction. In addition, the lock plate has a plurality of concave parts. In the lock plate, the projection height of a convex part between the concave part and the concave part is larger than the projection height of a convex part between the concave part and the concave part.

  • Patent number: 10677347
    Abstract: A shift lever is configured to take deceleration-requesting positions through its operation in a specified direction from an M-range position for a manual mode. A control is configured such that vehicle's deceleration is larger when an operational quantity of a one-time operation of the shift lever operated toward the deceleration-requesting positions B1, B2, B3 is larger. For example, when the shift lever is operated to the position B1, one-stage shift down is performed, when the shift lever is operated to the position B2, two-stage shift down is performed, and when the shift lever is operated to the position B3, three-stage shift down is performed.
