Remote support apparatus

1 . A remote support apparatus of remotely supporting a travelling of a vehicle,

the remote support apparatus comprising a remote support electronic control unit which communicates wirelessly with the vehicle,

wherein the remote support electronic control unit is configured to:

wirelessly acquire an image of a view in a travelling direction of the vehicle and display the acquired image by a displaying device of the remote support apparatus,

the image being taken by an imaging device of the vehicle; and

display a set steering angle line in the image displayed by the displaying device,

the set steering angle line being a line along which an outer portion of the vehicle during vehicle turning is predicted to move when the vehicle turns at a set steering angle,

the set steering angle not being an actual steering angle set by a remote operator who drives the vehicle remotely, and

the set steering angle being set based on at least one of a resolution of the image and an amount of delay of wireless communication with the vehicle.

2 . The remote support apparatus according to claim 1 , wherein the remote support electronic control unit is configured to set the set steering angle such that the set steering angle set when the resolution of the image corresponds to a first resolution, is smaller than the set steering angle set when the resolution of the image corresponds to a second resolution greater than the first resolution.

3 . The remote support apparatus according to claim 1 , wherein the remote support electronic control unit is configured to set the set steering angle such that the set steering angle set when the amount of delay of wireless communication with the vehicle corresponds to a first amount of delay, is greater than the set steering angle set when the amount of delay of corresponds to a second amount delay greater than the first amount of delay.

4 . The remote support apparatus according to claim 1 ,

wherein the vehicle is configured to automatically stop when wireless communication between the vehicle and the remote support electronic control unit is interrupted, and

wherein the remote support electronic control unit is configured to:

when a predicted vehicle stop position is within the image, display the predicted vehicle stop position in the image,

the predicted vehicle stop position being a position where the vehicle is predicted to automatically stop when the wireless communication between the vehicle and the remote support electronic control unit is interrupted; and

when the predicted vehicle stop position is not within the image, display the set steering angle line with a visibility higher than the visibility of the set steering angle line displayed when the predicted vehicle stop position is within the image.

5 . The remote support apparatus according to claim 1 , wherein the remote support electronic control unit is configured to display the set steering angle line in the image such that a visibility of the set steering angle line increases as a steering angle of the vehicle increases within a steering angle range equal to or smaller than the set steering angle.

6 . The remote support apparatus according to claim 1 , wherein the remote support electronic control unit is configured to display an inner rear wheel line in the image displayed by the displaying device, the inner rear wheel line being a line along which an inner rear wheel of the vehicle during vehicle turning is predicted to move.
