Lane guidance display system, method, and program

摘要

A lane guidance display system causes a display section to display a forward image on which a first guide line is superimposed in the case where a travel lane is not branched, the first guide line having, as an end point of the first guide line on the front side, a first front-side end point indicating the center position of the travel lane in the width direction, and causes the display section to display the forward image on which a second guide line is superimposed in the case where the travel lane is branched into a plurality of branched lanes, the second guide line having, as an end point of the second guide line on the front side, a second front-side end point indicating a position in the travel lane on the target lane side with respect to the center position of the travel lane in the width direction.

主权项

1. A lane guidance display system comprising:
a memory storing a lane guidance display program; and a processor that, when executing the stored program:
acquires a forward image in which a scene ahead of a vehicle is captured;specifies a travel lane currently traveled by the vehicle;determines whether the travel lane is branched into a plurality of branched lanes at a lane branch point ahead of the vehicle;determines whether the lane branch point is located within a predetermined distance ahead of the vehicle;determines whether a width of the travel lane is equal to or more than a predetermined width;when the travel lane is branched into a plurality of branched lanes at the lane branch point ahead of the vehicle, specifies a target lane to be traveled by the vehicle after traveling past the lane branch point;causes a display to display the forward image on which a first guide line is superimposed when the travel lane is not branched into a plurality of branched lanes, the first guide line having, as an end point of the first guide line on a front side, a first front-side end point indicating a center position of the travel lane in a width direction; andcauses the display to display the forward image on which a second guide line is superimposed when (i) the travel lane is branched into a plurality of branched lanes and the lane branch point is located within a predetermined distance ahead of the vehicle; or (ii) the travel lane is branched into a plurality of the branched lanes and a width of the travel lane is equal to or more than a predetermined width, the second guide line having, as an end point of the second guide line on the front side, a second front-side end point indicating a position in the travel lane on a target lane side with respect to the center position of the travel lane in the width direction.
