Abstract: In a sign information display system or method, if a road sign is recognized by a sign recognition device, a display control device determines whether or not it will cause a sign information display device to display first sign information, which is information concerning the road sign, on the basis of a driving state of a front vehicle driving in front of the vehicle.

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.

Abstract: If a first sign information detector 62 is normal, a first display 94 displays sign information detected by the first sign information detector 62, in accordance with an instruction from a control circuit 70. At this time, a second display 64 hides sign information in accordance with an instruction from the control circuit 70. On the other hand, if the first sign information detector 62 is abnormal, the first display 94 hides the sign information in accordance with an instruction from the control circuit 70. At this time, the second display 64 displays sign information detected by the second sign information detector 64, in accordance with an instruction from the control circuit 70.

Abstract: A sign information output apparatus includes an output instructor for instructing an information output section to stop output of sign information if a traveled distance measured in response to the detection of a sign exceeds a threshold value, and a threshold value changer for changing a threshold value depending on at least one of interval information with respect to an interval at which signs of one type are placed, speed limit information with respect to a speed limit of the road, and a speed of the vehicle.

Abstract: The regulatory sign or traffic information presented on a roadway is detected by capturing an image of ahead of a vehicle, and also the regulatory information is detected by receiving a signal transmitted from outside the vehicle. When the regulatory information is detected from the signal transmitted from outside the vehicle, that regulatory information is notified. When no regulatory information is detected from the signal transmitted from outside the vehicle, the regulatory information detected by capturing the image of ahead of the vehicle is notified.

Abstract: When normal maximum speed information (first sign information of first maximum speed) in a first section and school-zone maximum speed information (second sign information of second maximum speed) in a second section overlapping the first section are detected by a camera, an MID displays the normal maximum speed information and the school-zone maximum speed information side by side according to an instruction of an ECU.
