Has the advantages that: compared with the prior art, the utility model has the advantages of: through obtaining two adjacent vehicle distance information in real time, show three kinds of early warning information of first early warning information, second early warning information and third early warning information in real time and warn the navigating mate car distance whether safe, remind the navigating mate appropriately to adjust the car distance to effectively prevent the emergence of rear-end collision accident, especially in the dark tunnel to the very fast condition of highway speed of a motor vehicle and sight is not good.

Drawings

Fig. 1 is a schematic structural diagram of embodiment 1 of the present invention.

Fig. 2 is a schematic structural diagram of embodiment 2 of the present invention.

Fig. 3 is a structural diagram of the early warning module.

In the figure, a vehicle distance obtaining module 100, a distance comparing module 200, an early warning module 300, a vehicle speed obtaining module 400 and a distance calculating module 500 are provided.

Detailed Description

The invention will be further elucidated with reference to the drawings and the detailed description.

Example 1

As shown in fig. 1, the driving safety distance early warning device includes a distance obtaining module 100, a distance comparing module 200 and an early warning module 300, wherein the distance obtaining module 100 is configured to obtain a distance between two adjacent driving vehicles; the acquired distance between two adjacent vehicles can be the real-time head distance or the real-time tail distance between the current running vehicle and the previous running vehicle; the distance comparison module 200 is connected to the vehicle distance acquisition module 100, and is configured to compare the vehicle distance between two adjacent traveling vehicles acquired by the vehicle distance acquisition module 100 with the first safe vehicle distance and the second safe vehicle distance; the first safe vehicle distance and the second safe vehicle distance can be fixed values or real-time values determined according to the running speed of the current running vehicle; the early warning module 300 is connected to the distance comparison module 200, when the distance between two adjacent traveling vehicles acquired by the distance acquisition module 100 is not less than the first safe distance, the early warning module 300 displays the first early warning information, when the distance is less than the first safe distance and not less than the second safe distance, the early warning module 300 displays the second early warning information, and when the distance is less than the second safe distance, the early warning module 300 displays the third early warning information.

The driving safety distance early warning device can be used on an area expressway or used at an expressway tunnel entrance, a tunnel entrance or a tunnel exit due to the fact that the expressway is high in speed.

When the driving safety distance early warning device is used for an expressway or a tunnel entrance, it can be known from table 1 that when the designed speed of the expressway is 80KM/h, the required parking visual distance is 110 meters, and when the designed speed is 100KM/h, the required parking visual distance is 160M. Therefore, in the present invention, when the highway design speed is 80KM/H, the first safe distance can be set to a fixed value of 160m and the second safe distance can be set to a fixed value of 110 m according to table 1. Similarly, if the designed speed of a certain road is 100KM/H, the first safe distance may be 210 meters, and the second safe distance may be 160 meters.

The first early warning information of the driving safety distance early warning device is a green long-bright lamp, the second early warning information is a yellow flash lamp, the third early warning information is a red long-bright lamp, or other bright lamp colors and bright lamp forms are set according to requirements; as shown in fig. 3, the structure of the warning module may be configured such that the light arrangement shape of the first warning information displayed by the warning module 300 is an arrow shape (a), the light arrangement shape of the second warning information is a circle shape (b), and the light arrangement shape of the third warning information is an x shape (c).

Example 2

As shown in fig. 2, the driving safety distance warning device is the same as that in embodiment 1, except that the driving safety distance warning device further includes a vehicle speed obtaining module 400 and a distance calculating module 500; the vehicle speed obtaining module 400 is configured to obtain an operating speed of a current running vehicle.

The distance calculation module 500 is connected with the vehicle speed acquisition module 400 and the distance comparison module 200, and calculates and obtains a first safety distance and a second safety distance according to the running speed acquired by the vehicle speed acquisition module 400; through the vehicle speed obtaining module 400 and the distance calculating module 500, the real-time running speed of the running vehicle can be obtained, and the real-time first safe vehicle distance and the real-time second safe vehicle distance can be calculated according to the real-time running speed, when the vehicle speed is too fast, the numerical values of the first safe vehicle distance and the second safe vehicle distance can be reduced in real time due to the too fast vehicle speed, and therefore the early warning module 300 can be flexibly adjusted to output early warning information.
