Display system, display method, and display program

摘要

Display systems, methods, and programs generate and display an arrow object superimposed on an actual image of a road ahead of a vehicle. The systems, methods, and programs access information about a lane change route for guiding the vehicle when changing from a travel lane to a recommended lane. The systems, methods, and programs generate and display a travel lane part of the arrow object, a crossing part of the arrow object, and a recommended lane part of the arrow object, each as a superimposed image on the recommended lane. As remaining distance from a current position of the vehicle to the junction becomes smaller, a distance of a directional component along the travel lane for at least one of the travel lane part, the crossing part, and the recommended lane part is shortened.

主权项

1. A display system for generating and displaying an arrow object superimposed on an actual image of a road ahead of a vehicle, the display system comprising:
a controller that:
accesses information about a lane change route for guiding the vehicle when changing from a travel lane to a recommended lane, the travel lane being a lane in which the vehicle is currently traveling, the recommended lane being a lane that allows the vehicle to enter a lane in which the vehicle is to travel after passing through a road junction ahead of the vehicle;generates and displays a travel lane part of the arrow object, the travel lane part being displayed as a superimposed image on the travel lane;generates and displays a crossing part of the arrow object the crossing lane part being displayed as a superimposed image traversing from the travel lane to the recommended lane;generates and displays a recommended lane party of the arrow object, the recommended arrow lane part being displayed as a superimposed image on the recommended lane; andchanges a shape of the displayed arrow object such that, as a remaining distance from a current position of the vehicle to the junction becomes smaller, a total distance of a directional component along the travel lane for the travel lane part and a directional component along the travel lane for the crossing part is shortened while a total distance of the directional component along the travel lane for the travel lane part, the directional component along the travel lane for the crossing part, and a directional component along the travel lane for the recommended lane part does not change.
