First Claim
Patent Images
1. A sign display apparatus for a vehicle comprising:
- a sign information detector that detects sign information of a traffic sign existing on a road or on a road marking ahead of the vehicle;
a display device that displays the sign information detected by the sign information detector;
a control circuit configured to;
(i) control the display device;
(ii) detect an effective section of the detected traffic sign in which the traffic sign is considered to be effective;
(iii) determine whether or not the sign information detector detects a plurality of traffic signs having effective sections which overlap each other; and
(iv) determine whether or not the detected sign information contains textural information including a predetermined or more number of characters; and
a memory which stores therein simplified information of a corresponding traffic sign, whereinwhen it is determined that the sign information detector detects the plurality of traffic signs having the overlapping effective sections or it is determined that when the detected sign information contains textural information including the predetermined or more number of characters, the display device is controlled to display the simplified information of at least one of the traffic signs or of the traffic sign containing the textural information.

Abstract
Sign information of a traffic sign or a road marking ahead of a vehicle is detected. When two or more kinds of sign information having overlapping effective sections are detected or when the sign information contains textural information including a predetermined or more number of characters, simplified information obtained by simplifying the sign information is displayed on an MID in the vehicle.

8. A sign display method for a vehicle comprising:
-
detecting sign information of a traffic sign existing on a road or a road marking ahead of the vehicle; detecting an effective section of the detected traffic sign in which the traffic sign is considered to be effective; providing simplified information of a corresponding traffic sign by simplifying the sign information of the traffic sign in a predetermined manner; determining whether or not a plurality of traffic signs having effective sections which overlap each other are detected; determining whether or not the detected sign information contains textural information including a predetermined number or more of characters; and when the sign information detector detects the plurality of traffic signs having the overlapping effective sections or when the detected sign information contains the textural information including the predetermined or more number of characters, displaying the simplified information of at least one of the traffic signs or of the corresponding traffic sign containing the textural information on a display device of the vehicle.
