Abstract: The relative position between a vehicle and an extension unit located outside the vehicle is detected, and a command touch operation for operating the vehicle with a remote operation device is set in accordance with the detected relative position. The touch operation of an operator is detected by a touch panel of the remote operation device, and a determination is made as to whether or not the detected touch operation is the command touch operation. When the touch operation is the command touch operation, the vehicle is controlled to execute autonomous travel control. The vehicle has an autonomous travel control function.

Abstract: A parking control method includes: performing parking control of moving a vehicle to a target parking position on the basis of an operation command acquired from an operator located outside the vehicle; when the parking control to the target parking position is suspended and the vehicle leaves the target parking position, calculating a moving direction of the vehicle on the basis of a parking direction when the vehicle is parked at a next target parking position; and moving the vehicle in the moving direction.

Abstract: A vehicle remote control method controls a vehicle having an autonomous travel control function to execute autonomous travel control. The method includes detecting an input position at which a touch operation is performed by an operator on a touch panel of a remote operation device and making a gesture determination area variable in accordance with the input position. The gesture determination area is an area in which a gesture for remotely controlling the vehicle is received. The method further includes detecting the gesture from the gesture determination area and determining whether or not the detected gesture is a command gesture that is preliminarily set. When the gesture is the command gesture, the vehicle is controlled to execute the autonomous travel control.

Abstract: A parking control method includes: performing parking control of moving a vehicle to a target parking position on the basis of an operation command acquired from an operator located outside the vehicle; and when the parking control to the target parking position is suspended and the vehicle leaves the target parking position, moving the vehicle so that at least part of the vehicle is present within a predetermined range from the operator.

Abstract: In a parking assistance method of a parking control device which executes parking control with respect to a free parking space surroundings a host vehicle, a first frame line of free parking space in a direction orthogonal to a vehicle width direction and a second frame line which forms a pair with the first frame line are detected, and a parking target is set on a straight line connecting between a point on the first frame line and a point on the second frame line, for example, the parking target is set on the straight line connecting between an end on the first frame line and an end on the second frame line, and parking control is executed so that a position of wheels of the host vehicle is matched with the parking target.

Abstract: A parking control method includes: performing parking control of moving a vehicle to a target parking position on the basis of an operation command acquired from an operator located outside the vehicle; when the parking control to the target parking position is suspended and the vehicle leaves the target parking position, calculating a moving direction of the vehicle on the basis of a traffic direction in a passage for vehicles adjacent to the target parking position; and moving the vehicle in the calculated moving direction.

Abstract: A parking control method includes: performing parking control of moving a vehicle to a target parking position on the basis of an operation command acquired from an operator located outside the vehicle; and when the parking control to the target parking position is suspended and the vehicle leaves the target parking position, moving the vehicle so that at least part of the vehicle is present within a predetermined range from the operator.

Abstract: A parking assistance device includes: a surrounding-image generation circuit that generates a surrounding image that is a view of surroundings of a mobile object from above; an image display circuit that displays an assistance image at a position of an empty parking space in the surrounding image, the first assistance image indicating the empty parking space; and a turning determination circuit that determines whether the mobile object is turning. In a case where it is determined by the turning determination circuit that the mobile object is turning, the image display circuit prohibits the assistance image from being displayed.

Abstract: A parking assistance method of a parking assistance device for generating a peripheral image indicating a periphery of a vehicle as viewed from above to detect an unoccupied parking space, and displaying, on the peripheral image, an assistance image indicating that the detected unoccupied parking space is an available parking space, determines whether the vehicle intrudes on the unoccupied parking space. The parking assistance method inhibits the assistance image from being displayed on the unoccupied parking space on which the vehicle is determined to intrude in the peripheral image.

Abstract: First information including operation information is exchanged via a first communication path. Second information including presentation information regarding parking control is exchanged via a second communication path. The presentation information is presented on an operation terminal. When a first evaluation value of the first communication path is less than a first threshold, at least part of the first information is exchanged via one or more other communication paths. When a second evaluation value of the second communication path is less than a second threshold, at least part of the second information is exchanged via one or more other communication paths, and an information amount of the first information and/or the second information is reduced. A vehicle is parked in accordance with a control instruction for moving along a parking route. The control instruction is based on the operation information which is input to the external operation terminal.
