Display system and display program
An in-vehicle device displaying travel lanes of a vehicle in a predetermined number of display boxes includes an identifying part that identifies travel lanes to be displayed in the display boxes, and identifies travel lanes so a recommended lane which is a travel lane recommended for the vehicle to travel is displayed in one of the display boxes and a maximum number of recommended travel lanes which are travel lanes coinciding with a traveling direction of the recommended lane each are displayed in one of the display boxes; and a display part that displays the identified travel lanes in the display boxes. The identifying part identifies travel lanes while relatively shifting in turn a plurality of travel lanes and the display boxes from a travel lane at one end of the plurality of travel lanes that are on a traveling direction side of the vehicle and being adjacent to each other.
1. A display system that displays travel lanes of a vehicle in a predetermined number of display boxes, the display system comprising:
an identifying part for identifying travel lanes that can be displayed in the display boxes, and identifying travel lanes such that a recommended lane is displayed in one of the display boxes and a maximum number of recommended travel lanes each are displayed in a different one of the display boxes, the recommended lane being a travel lane recommended for the vehicle to travel, and the recommended travel lanes being travel lanes whose traveling directions coincide with a traveling direction of the recommended lane; and
a display part for displaying the travel lanes identified by the identifying part in the display boxes, wherein the identifying part identifies travel lanes that can be displayed in the display boxes, while relatively shifting in turn a plurality of travel lanes and the display boxes from a travel lane at one end of a plurality of travel lanes, the plurality of travel lanes being on a traveling direction side of the vehicle and being adjacent to each other.
2. The display system according to claim 1 , wherein the identifying part identifies travel lanes that can be displayed in the display boxes, by identifying locations of corresponding ones of the display boxes including a maximum number of the recommended travel lanes from among locations of the display boxes for a plurality of travel lanes obtained when the predetermined number of the display boxes are sequentially shifted.
3. A display system that displays travel lanes of a vehicle in a predetermined number of display boxes, the display system comprising:
an identifying part for identifying travel lanes that can be displayed in the display boxes, and identifying travel lanes such that a recommended lane is displayed in one of the display boxes and a maximum number of recommended travel lanes each are displayed in a different one of the display boxes, the recommended lane being a travel lane recommended for the vehicle to travel, and the recommended travel lanes being travel lanes whose traveling directions coincide with a traveling direction of the recommended lane; and
a display part for displaying the travel lanes identified by the identifying part in the display boxes, wherein
when a travel lane that is not displayed is present adjacent to a travel lane to be displayed in a display box at an end of the plurality of display boxes, the identifying part determines that the display box at the end is a display prohibited box that does not display a travel lane,
the identifying part identifies travel lanes such that in display permitted boxes, the recommended lane is displayed and a maximum number of the recommended travel lanes are displayed, the display permitted boxes being those of the plurality of display boxes other than the display prohibited box, and
the display part displays, in the display prohibited box, information indicating that in addition to travel lanes displayed in the display permitted boxes, a not-displayed travel lane is also present on the display prohibited box side of the plurality of display boxes.
4. A non-transitory recordable storage medium storing a display program that displays travel lanes of a vehicle in a predetermined number of display boxes, the display program causing a computer to function as:
an identifying part for identifying travel lanes that can be displayed in the display boxes, and identifying travel lanes such that a recommended lane is displayed in one of the display boxes and a maximum number of recommended travel lanes each are displayed in a different one of the display boxes, the recommended lane being a travel lane recommended for the vehicle to travel, and the recommended travel lanes being travel lanes whose traveling directions coincide with a traveling direction of the recommended lane; and
a display part for displaying the travel lanes identified by the identifying part in the display boxes,
wherein the identifying part identifies travel lanes that can be displayed in the display boxes, while relatively shifting in turn a plurality of travel lanes and the display boxes from a travel lane at one end of a plurality of travel lanes, the plurality of travel lanes being on a traveling direction side of the vehicle and being adjacent to each other.
