US-12619246-B2 - Remote support apparatus

Abstract

A remote support apparatus remotely supports a travelling of a vehicle. The remote support apparatus communicates wirelessly with the vehicle. The remote support apparatus wirelessly acquires 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 is taken by an imaging device of the vehicle. The remote support apparatus displays an inner rear wheel line in the image displayed by the displaying device while the vehicle is turning. The inner rear wheel line is a line along which an inner rear wheel of the vehicle during vehicle turning is predicted to move.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to Japanese patent application No. JP 2023-092548 filed on Jun. 5, 2023, the content of which is hereby incorporated by reference in its entirety. BACKGROUND Field The present invention relates to a remote support apparatus. Description of the Related Art There is known a remote support apparatus which remotely supports a travelling of a vehicle. As the remote support apparatus, there is also known a remote support apparatus which is configured to provide a remote driver or an operator who remotely drives the vehicle, using the remote support apparatus with information on a travelling route for the vehicle by displaying the travelling route for the vehicle on a display of the remote support apparatus (for example, refer to JP 2022-174921 A). When the remote driver recognizes a future travelling of the vehicle while the vehicle is turning, the remote driver can easily support the travelling of the vehicle by the remote support apparatus. SUMMARY An object of the present invention is to provide a remote support apparatus which remotely supports the travelling of the vehicle and can help the remote driver recognize the future travelling of the vehicle. A remote support apparatus according to the present invention remotely supports a travelling of a vehicle. The remote support apparatus comprises a remote support electronic control unit which communicates wirelessly with the vehicle. 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 is taken by an imaging device of the vehicle. The remote support electronic control unit is further configured to display an inner rear wheel line in the image displayed by the displaying device while the vehicle is turning. The inner rear wheel line is a line along which an inner rear wheel of the vehicle during vehicle turning is predicted to move. With the remote support apparatus according to the present invention, the inner rear wheel line is displayed in the image of the view in the travelling direction of the vehicle while the vehicle is turning. Thus, a remote driver or an operator who remotely supports a travelling of the vehicle by operating the remote support apparatus, can recognize a future travelling of the vehicle. In the remote support apparatus according to an aspect of the present invention, the remote support electronic control unit may be further configured to display the inner rear wheel line at a position in the image. The position is a position where the inner rear wheel of the vehicle is predicted to move. The remote support electronic control unit may be further configured to predict the inner rear wheel line having a length such that the length when a steering angle of the vehicle corresponds to a first steering wheel, is shorter than the length when the steering angle of the vehicle corresponds to a second steering angle greater than the first steering angle. With the remote support apparatus according to this aspect of the present invention, when the steering angle of the vehicle is great, the predicted inner rear wheel line has the longer length. Thus, even when the steering angle of the vehicle is great, the inner rear wheel line can be displayed. In the remote support apparatus according to another aspect of the invention, the remote support electronic control unit may be further configured to display the inner rear wheel line in the image when a steering angle of the vehicle is equal to or greater than a predetermined displaying steering angle. With the remote support apparatus according to this aspect of the present invention, when the steering angle of the vehicle is great, the inner rear wheel line is displayed. Thus, the inner rear wheel line can be displayed, depending on a necessity of displaying the inner rear wheel line. In the remote support apparatus according to further another aspect of the present invention, the remote support electronic control unit may be further configured to display the inner rear wheel line in the image when a travelling speed of the vehicle is equal to or smaller than a predetermined displaying speed. With the remote support apparatus according to this aspect of the present invention, when the travelling speed of the vehicle is low, the inner rear wheel line is displayed. Thus, the inner rear wheel line can be displayed, depending on a necessity of displaying the inner rear wheel line. In the remote support apparatus according to further another aspect of the present invention, the remote support electronic control unit may be further configured to display the inner rear wheel line in the image when the inner rear wheel line crosses an object in the image. The remote support apparatus according to this aspect of the present invention can enable a user of the rem
