Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle display device for displaying an inter-vehicle distance, and more particularly, to a vehicle provided with a follow-up traveling system that travels with a proper inter-vehicle distance from a preceding vehicle. The present invention relates to a vehicle display device.

[0002]

2. Description of the Related Art Hitherto, there has been proposed a follow-up traveling system which controls a vehicle speed so as to follow a preceding vehicle while maintaining a safe inter-vehicle distance.
And JP-A-9-126790. Such a follow-up traveling system is provided with a distance sensor at a front portion of the vehicle, detects a distance from the own vehicle to a preceding vehicle by using the distance sensor, and controls the own vehicle so that an inter-vehicle distance between the own vehicle and the preceding vehicle becomes appropriate. Is to control the speed. The host vehicle travels at a speed set by the driver in advance, but travels so as to follow the preceding vehicle when catching up with the preceding vehicle.

FIG. 7 shows a vehicle equipped with a follow-up traveling system.
The following display device is provided. Reference numeral 1 denotes a liquid crystal display element. The liquid crystal display element 1 has a first display segment 2, a second display segment 3, and third display segments 4, 5, and 6. First display segment 2
The outline of the second display segment has a vehicle shape, the first display segment 2 shows the own vehicle, and the second display segment 3 shows the preceding vehicle. The third display segments 4, 5, and 6 display a bar graph of the distance from the host vehicle to the preceding vehicle. Reference numeral 7 denotes a set speed display unit, and the set speed display unit 7 digitally displays the speed set by the driver.

As shown in FIG. 8, the liquid crystal display element 1 displays the inter-vehicle distance by changing the number of the third display segments 4, 5, 6 to be turned on. That is, when the inter-vehicle distance is long, the three third display segments 4, 5, and 6 are turned on (see FIG. 8A), and when the inter-vehicle distance is medium, two third display segments are turned on. 4 and 5 are turned on (see FIG. 8 (b)), and when the inter-vehicle distance is short, one third display segment 4 is turned on (see FIG. 8 (c)) to display the inter-vehicle distance.

[0005]

However, the number of the illuminated third display segments 4, 5, and 6 alone is not enough.
There was a problem that it was difficult to grasp the inter-vehicle distance. That is, since the distance D from the first display unit 2 showing the own vehicle to the second display unit 3 showing the preceding vehicle does not change, the instant readability is not always excellent. The present invention has been made in view of this problem, and has as its object to provide a vehicular display device that makes it easy to grasp the distance from the host vehicle to a preceding vehicle.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a first display unit showing a host vehicle and a plurality of second display units showing a preceding vehicle running ahead of the host vehicle. And 1 according to the distance from the host vehicle to the preceding vehicle.
Control means for turning on the second display units and turning off the other second display units.

Further, according to the present invention, a plurality of third display portions indicating the distance are provided within an outline of the second display portion.

[0008] The present invention also provides a plurality of first display units indicating a host vehicle, a second display unit indicating a preceding vehicle traveling in front of the host vehicle, and a plurality of first display units indicating the preceding vehicle. Control means for turning on one first display unit and turning off the other first display units according to the distance.

Further, according to the present invention, a plurality of third display portions indicating the distance are provided within the outline of the first display portion.

Further, in the present invention, the outline of the first display portion and the second display portion has a vehicle shape.
