  • Publication number: 20240152138
    Abstract: An object of the present disclosure is to provide a technique that enables a remote operator to operate a vehicle in the same manner as a driver who gets in the vehicle. A vehicle control system that controls a vehicle based on an operation amount input by a remote operator includes one or more processors. When a vehicle stop hold function for holding a vehicle stop state is operated, the one or more processors continue the operation of the vehicle stop holding function when there is no input of an accelerator operation by a remote operator, and cancel the operation of the vehicle stop holding function when the input of the accelerator operation by the remote operator is received.

  • Publication number: 20240134374
    Abstract: A remote operation control method for controlling a remote operation of a moving body is provided. A video captured by a camera mounted on the moving body is transmitted to a remote operator terminal on a side of a remote operator remotely operating the moving body. The remote operation control method includes: setting an upper limit speed of the moving body during the remote operation to be lower as a quality of the video transmitted from the moving body to the remote operator terminal becomes lower or as an encoding and decoding time of the video becomes longer; and limiting a speed of the moving body during the remote operation to the upper limit speed or less regardless of an operation amount input by the remote operator.

  • 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: 20240067172
    Abstract: A moving body control system determines, during execution of a remote operation of a moving body, whether a predetermined condition is satisfied based on driving environment information indicating the driving environment for the moving body. When the predetermined condition is satisfied, the moving body control system issues a notification to rearward of the moving body, the notification prompting to pass the moving body. Meanwhile, when the predetermined condition is not satisfied, the moving body control system prohibit issuance of the notification. The predetermined condition includes at least a first condition that “the moving body is in an environment where passing is legally permitted”, and a second condition that “safety when the moving body is passed is ensured”.

  • Patent number: 11780454
    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.

  • Publication number: 20230130192
    Abstract: The vehicle steering system includes a controller for controlling the reaction device for applying reaction torque to a steering wheel. The controller sets a virtual end angle corresponding to a turning limit of a turning device with respect to a steering angle. When the steering angle approaches the virtual end angle, the controller gradually increases the reaction torque as the steering angle approaches the virtual end angle. On the other hand, when the steering angle deviates from the virtual end angle, the controller decreases the reaction torque with respect to the change in the steering angle at a steeper gradient than the gradient of the change in the reaction torque with respect to the change in the steering angle when the steering angle approaches the virtual end angle.
