  • Publication number: 20240085905
    Abstract: The vehicle includes a driving operation member that is operated by an operator to perform steering, acceleration, and deceleration, a stop maintaining device that maintains a stop state, and a control device. In the remote control mode, the control device communicates with the remote operation target vehicle, transmits information reflecting the operation amount of the driving operation member to the remote operation target vehicle, and presents information received from the remote operation target vehicle to the operator. When the stop state of the vehicle is not maintained by the stop maintaining device, the control device prohibits the remote control mode.

  • Publication number: 20230406334
    Abstract: A vehicle is operated in accordance with a second operation amount corresponding to a first operation amount of a remote operation member by an operator. A first maximum operation range is a maximum operation range of the remote operation member. A second maximum operation range is a maximum operation range of an operation member of the vehicle. When the first maximum operation range is smaller than the second maximum operation range, a correspondence relationship between the first and second operation amounts is adjusted such that the second operation amount becomes larger than the first operation amount. When the first maximum operation range is larger than the second maximum operation range, an operable range of the remote operation member is restricted or the correspondence relationship is adjusted such that the second operation amount becomes smaller than the first operation amount.
