Abstract

An information display device includes: a display section that displays a view of a situation ahead of a vehicle and guidance information; a learning section that classifies and learns targets appearing on a travel route and visible through the display section as: a first target necessary to be visible, a second target necessary to be visible under the setting condition, or a third target not necessary to be visible, and a display control section configured to: prohibit display of the guidance information in a prohibited region with the first target, permit display of the guidance information in a permitted region with the third target, and either prohibit display of the guidance information in a conditional region with the second target and the setting condition is met, or permit display of the guidance information in the conditional region with the second target and the setting condition is not met.

First claim

What is claimed is:

1 . An information display device comprising:
a display section that is provided to a vehicle, and that is configured capable of displaying a view of a situation ahead of the vehicle to be viewed and displaying guidance information; a memory; and a processor that is couple to the memory and that is configured to: learn and classify targets appearing on a travel route of the vehicle and visible through the display section as:
a first target that is necessary to be visible regardless of a setting condition,
a second target that is necessary to be visible under the setting condition, or
a third target that is not necessary to be visible, and performing display control including:
prohibiting display of the guidance information in a prohibited region of the display section in which the first target is present,
permitting display of the guidance information in a permitted region of the display section in which the third target is present, and
either prohibiting display of the guidance information in a conditional region of the display section in which the second target is present in a case in which the setting condition is met, or permitting display of the guidance information in the conditional region in a case in which the setting condition is not met.

2 . The information display device of claim 1 , wherein the display control further includes:
repositioning display of the guidance information from the conditional region to the permitted region in a case in which the conditional region continues in a next segment of the travel route.

3 . The information display device of claim 1 , wherein:
the display section is configured capable of changing a display transparency level of the guidance information; and the display control further includes, in a case in which the conditional region will no longer be present in a next segment of the travel route, displaying the guidance information in the conditional region with the display transparency level of the guidance information raised in comparison to the display transparency level of the guidance information when displayed in the next segment of the travel route.

4 . The information display device of claim 1 , wherein the processor is further configured to:
learn time-of-day information indicating a time when at least the second target appears, and a reduced frequency time-of-day indicating a time when a frequency of appearance of the second target is reduced compared to the frequency of appearance of the second target at other times of day, the reduced frequency time-of-day being included in a condition for a case in which the setting condition is not met; and the display control includes permitting display of the guidance information in the conditional region at the reduced frequency time-of-day.

5 . A control method of an information display device including a display section provided to a vehicle and configured capable of displaying a view of a situation ahead of the vehicle and displaying guidance information, the control method comprising:
leaning and classifying targets appearing on a travel route of the vehicle and visible through the display section as
a first target that is necessary to be visible regardless of a setting condition,
a second target that is necessary to be visible under the setting condition, or
a third target that is not necessary to be visible; and
performing display control that includes:
prohibiting display of the guidance information on the display section in a prohibited region of the display section in which the first target is present,
permitting display of the guidance information on the display section in a permitted region of the display section in which the third target is present, and
either prohibiting display of the guidance information in a conditional region of the display section in which the second target is present in a case in which the setting condition is met, or permitting display of the guidance information in the conditional region in a case in which the setting condition is not met.

6 . A non-transitory storage medium storing a program that causes a computer to execute control processing of an information display device, the information display device comprising a display section provided to a vehicle and configured capable of displaying a view of a situation ahead of the vehicle and displaying guidance information, the control processing comprising:
learning and classifying targets appearing on a travel route of the vehicle and visible through the display section as:
a first target that is necessary to be visible regardless of a setting condition,
a second target that is necessary to be visible under the setting condition, or
a third target that is not necessary to be visible; and
performing display control including:
prohibiting display of the guidance information on the display section in a prohibited region of the display section in which the first target is present,
permit displaying of the guidance information on the display section in a permitted region of the display section in which the third target is present, and
either prohibiting display of the guidance information in a conditional region of the display section in which the second target is present in a case in which the setting condition is met, or permitting display of the guidance information in the conditional region in a case in which the setting condition is not met.
