  • Publication number: 20220366731
    Abstract: A vehicle control device includes an acquisition unit configured to acquire detection information in a current traveling state and position information indicating a current position of a vehicle, a transmission unit configured to transmit traveling information in which the detection information and the position information are associated with each other to an external management device, a reception unit configured to receive changed specification information of the vehicle transmitted when the management device determines that specifications of the vehicle need to be changed, and a control unit configured to change the specifications of the vehicle corresponding to the specification information and reflect the changed specifications in traveling control.

  • Patent number: 7543825
    Abstract: A four-wheel vehicle is provided with an in-wheel motor in each of a front wheel and a rear wheel and has approximately the same roll center heights of the front wheel and the rear wheel. The relation between a change in a kingpin offset and a change in a wheel stroke for at least any one of the front wheel and the rear wheel of the four-wheel vehicle is determined based on at least any one of braking force distribution and driving force distribution between the front wheel and the rear wheel.

  • Patent number: 5024117
    Abstract: An apparatus is provided for supporting a shift lever for a transmission the shift lever including a ball-like portion which is on the shift lever and has spherical surfaces of a fixed curvature at least on a part of the lower and upper sides. A receiving surface has a concave spherical surface of nearly the same curvature as the lower spherical surface of the ball-like portion and is in contact with the lower spherical surface, and a retaining surface has a concave spherical surface in surface contact with the upper spherical surface of the ball-like portion and holds the ball-like portion between the concave spherical surface and the receiving surface. A retaining member is installed from above to cover the ball-like portion, and an elastic displacement section is projectingly formed on the lower side of the retaining member to enclose the upper part of the ball-like portion and is elastically deformable in the radial direction of the ball-like portion.

  • Patent number: 4873884
    Abstract: A shift lever supporting apparatus for a transmission, has an integral structure comprising a cylindrical shift lever mounting portion for receiving a ball portion of a shift lever, a pyramidal retainer portion contiguously provided below the shift lever mounting portion, a plate portion contiguously provided below the retainer portion, and a bearing portion for mounting a select bell-crank, the bearing portion being contiguously provided on the retainer portion and in close proximity to the shift lever mounting portion. The shift lever mounting portion is provided with a seat surface for supporting the ball portion of the shift lever, and a U-shaped notch which allows insertion of a select lever extending from the ball portion. The ball portion of the shift lever is inserted into the shift lever mounting portion from the upper side and this ball portion is pressed against and thereby retained on the seat surface by the use of a cap.
