Next, the present invention will be described with reference to the drawings. FIG. 1 is a rear view of an automobile showing an embodiment of a driving status display device for an automobile or a motorcycle according to the present invention. In the center of the rear part of the vehicle body 10, a speed display means 12 for digitally displaying the running speed of the vehicle is provided. The digitally displayed numbers on the speed display means 12 are linked with the accelerator, and increase when the accelerator is depressed, gradually decrease when the engine brake is applied, and decrease rapidly when the brake is depressed. In this way, the driver of the following vehicle can recognize the running speed of the preceding vehicle by the digital numbers of the speed display means 12, so that the driver of the following vehicle can grasp the difference in speed from the preceding vehicle, and Before the brake lamp is turned on, the driver can step on the brake or apply the engine brake to secure a safe inter-vehicle distance with the preceding vehicle. As a result, the incidence of accidents such as rear-end collisions can be significantly reduced as compared with the related art.

FIG. 2 shows another embodiment of the driving status display device for a car or a motorcycle according to the present invention. At the rear center of the body 10 of the vehicle, there is provided speed display means 14 for displaying the running speed of the vehicle in an analog manner. The speed display means 14 has a display section 16 that indicates the speed of the vehicle as the length of light, and increases or decreases the length of light that is lit on the display section 16 according to the speed. For example, it is assumed that the display unit 16 is long in the horizontal direction, the traveling speed is 0 Km at the left end of the display unit 16, and the traveling speed is 200 km at the right end.
If Km is set, for example, if the traveling speed is 50 km, the length from the left end of the entire length of the display unit 16 in the horizontal direction to a quarter point is lit. If the traveling speed is 150 Km, the length from the left end of the total length of the display unit 16 in the horizontal direction to three-quarters is turned on. With this configuration, the traveling speed of the preceding vehicle can be recognized by looking at the length of light on the display unit 16 of the preceding vehicle, and the driver of the following vehicle can brake before the brake lamp of the preceding vehicle comes on. By stepping on the vehicle or applying engine braking, a safe inter-vehicle distance with the preceding vehicle can be ensured. Although the display unit 16 is long in the horizontal direction, it may be long in the vertical direction.

If a speed numeral 18 serving as a delimiter, for example, 50 km, 100 km, or 150 km is displayed in the vicinity of the inside or outside of the display unit 16, the length of the light on the display unit 16 of the preceding vehicle and the speed numeral are displayed. By looking at 18, it is possible to recognize the approximate traveling speed of the preceding vehicle. Note that, for example, 50 km, 100 km,
A mark 20 for separation such as a thick line is provided so that the speed of the separation such as 50 km can be seen at a glance from the following vehicle. If the speed numeral 18 or the mark 20 emits light itself or is coated with luminous paint, the traveling speed of the preceding vehicle can be sufficiently recognized even at night. The overall length of the display section 16 in the speed display means 14 in the horizontal direction is arranged so as to be equidistant from the center of the rear part of the vehicle body 10 to the left and right. With this, if the position of the center of the display unit 16 is set to, for example, 100 km, even if the speed numeral 18 and the mark 20 are not visible, the front end position of the display unit 16 of the preceding vehicle in the lateral direction of the light can be viewed. Thus, the traveling speed of the preceding vehicle can be roughly recognized. For example, if the lateral extension end of the light is located on the left side of the center of the vehicle body 10, it is 100 km or less, and depending on whether the extension end position is near the center or farther from the center, The approximate traveling speed of the car can be almost recognized.
