  • Patent number: 11952821
    Abstract: A control device is mounted on a vehicle including a door opening and closing mechanism for opening and closing a door of an entrance and exit where a passenger gets on and off, and a shift device for changing a driving range of a transmission. The driving range is input to the control device and the control device opens and closes the door by the door opening and closing mechanism. The control device permits opening of the door when the driving range is a parking range, and prohibits a change of the driving range of the shift device when the driving range is the parking range and the door is open.

  • Publication number: 20230242040
    Abstract: A vehicle ramp deployment apparatus is mounted on a vehicle, for deploying a ramp from a vehicle body and retracting the ramp into the vehicle body. The vehicle ramp deployment apparatus includes an electric motor configured to drive the ramp for a deploying or retracting operation, an ECU configured to execute driving control of the electric motor and to execute stop retaining control of the electric motor to retain a stopped state of the electric motor, and a pulse sensor configured to detect rotation of the electric motor. The ECU is configured to shift from the stop retaining control to power save control in response to detection, with the rotation sensor, of the electric motor having not been rotated for a predetermined time period.

  • Publication number: 20220332240
    Abstract: A ramp-equipped vehicle includes a ramp that is provided so as to be deployable from a side portion of a vehicle body to the outside of the vehicle body, a controller that controls the operation of deploying the ramp, and a sensor that senses moving bodies present in a certain area that is away from a ramp deployment area. The controller detects the moving bodies approaching the ramp deployment area and determines the moving velocities of the moving bodies based on the results of sensing by the sensor. The controller stops the operation of deploying the ramp when, after the start of the operation of deploying the ramp, it detects the approaching moving body having a moving velocity higher than or equal to a predetermined reference velocity with which the approaching moving bodies may reach the ramp deployment area during the operation of deploying the ramp.

  • Publication number: 20220306071
    Abstract: A vehicle includes a slope device configured to perform deployment and storage of a slope, a camera, and a door and slope control device configured to communicate with a server including a getting-on reservation database including attribute information of a passenger, and perform deployment and storage of the slope by the slope device, in which the door and slope control device is configured to, when the vehicle is stopped to allow the passenger to get on the vehicle, confirm the attribute information of the passenger acquired from the getting-on reservation database of the server based on an image of the passenger captured by the camera, and perform deployment of the slope depending on the confirmed attribute information.

  • Publication number: 20220305977
    Abstract: A ramp system includes: a ramp main body provided in a door opening and configured to be able to advance from a vehicle floor toward a road surface; a ramp-state detection device configured to detect an advancing-retracting state of the ramp main body; a display device configured to display an image in a display area observable from an operator seat; and a UI controller configured to control display on the display device. The UI controller causes the display device to display a state image including an image indicative of the advancing-retracting state.

  • Publication number: 20220218541
    Abstract: A control device of a vehicle is installed in a vehicle including: a body having a vehicle cabin and a floor panel constituting a floor of the vehicle cabin; a door opening-closing mechanism that drives a door mounted on the body to open and close; and a slope deploying mechanism that deploys a slope plate housed under the floor panel to the outside of the body. The control device coordinates the operation of the door opening-closing mechanism and the slope deploying mechanism. The control device opens the door by the door opening-closing mechanism after deploying the slope plate toward the outside of the body by the slope deploying mechanism.
