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.

Remote operation control method, remote operation system, and moving body

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”.

A method for a remote driving of a mobile vehicle having wheels is provided.

In a steering system including a steering operation mechanism, a second actuator, a steering angle sensor, a steering torque sensor, and a steering operation control device and a control method for the steering system, only a drive assist target steered angle (first target steered angle) is reflected in a final target steered angle when a torque sensor value (actual steering torque) detected by the steering torque sensor is equal to or less than an intervention threshold. When the magnitude of the torque sensor value is more than the intervention threshold, the rate of reflection (distribution ratio) of a driver target steered angle (second target steered angle) in the final target steered angle is raised as the torque sensor value is increased, and the rate of reflection of the driver target steered angle in the final target steered angle is lowered as the magnitude of the torque sensor value is decreased.

A steer-by-wire steering system for a vehicle, comprising: an operation member operable by a vehicle driver; an urging device configured to generate an urging force to urge the operation member; a steering device configured to steer a wheel; and a controller configured to control the urging device and the steering device. In a normal operation, the controller enables the wheel to be steered in accordance with an operation of the operation member and causes the urging force to function as an operation reaction force against the operation of the operation member. In an automatic steering operation in which the wheel is steered without depending on the operation of the operation member, the controller enables the operation member to be moved in accordance with steering of the wheel by the urging force and causes at least part of the urging force generated in the normal operation not to be generated.

Steer-by wire steering system

A vehicle control system for a steer-by-wire vehicle executes: driving assist control that assists driving of the vehicle; and conjunction reaction force control that applies a steering reaction force component to a steering wheel in conjunction with vehicle turning caused by the driving assist control. A driver turn angle is a target turn angle corresponding to a steering angle of the steering wheel, and a first system turn angle is a target turn angle required by the driving assist control. In the conjunction reaction force control, a second system turn angle is acquired by adjusting the first system turn angle according to a driver's steering intention such that the difference between the system turn angle and the driver turn angle becomes smaller. Then, a steering reaction force component is applied in a direction of reducing a difference between the driver turn angle and the second system turn angle.
