Problems solved by technology

This technology can only provide convenience for others, but cannot identify the distance between vehicles. If the vehicle can drive safely, it needs to be installed on all vehicles. If one vehicle is not installed, other vehicles may have potential safety hazards.

Embodiment Construction

[0024] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0025] Fog vehicle driving warning device provided by the present invention, as figure 1 As shown, it includes: ranging radar sensor, laser radar visibility meter, GPS speed measurement module, integrated control unit; the foggy vehicle driving warning device can be installed on the required vehicle;

[0026] The distance measuring radar sensor measures the distance of the target ahead by transmitting radio waves to the detection area ahead, using the time delay between the received target reflection signal and the transmitted signal; the target ahead may be other vehicles ahead or obstacles on the road;

[0027] The lidar visibility meter is used to measure the current visibility index;

[0028] The GPS speed measurement module utilizes real-time GPS signals to obtain the absolute speed of the vehicle;

[0029] The integrated control unit processes and obtai...

Abstract

The invention provides a vehicle driving early warning device in a fog installed on a vehicle. The device comprises a ranging radar sensor, a laser radar visibility meter, a GPS speed measuring module, and an integration control unit. The ranging radar sensor transmits a radio wave to a front detection area, and by using the received time delay of a target reflection signal and an emitting signal, a front target distance is measured. The laser radar visibility meter can be used to measure a current visibility indicator. The GPS speed measuring module obtains a vehicle absolute speed by using a real-time GPS signal. The integration control unit carries out processing and obtains the safety state of vehicle operation according to the information outputted by the ranging radar sensor, the laser radar visibility meter, and the GPS speed measuring module and carries out early alarming. According to the vehicle driving early warning device, the safety factor of driving of a driver in a fog can be improved, and traffic accidents caused by weather can be reduced.

Description

technical field [0001] The invention relates to a vehicle safety device, in particular to a vehicle driving warning device. Background technique [0002] my country's expressway construction has entered a period of high-speed development, and with it, traffic accidents continue to increase, and traffic safety problems are becoming more and more serious. According to statistics, traffic accidents directly or indirectly caused by disastrous weather account for about 1 / 4 of the total accidents, especially dense fog, which is known as the "killer" of high-level highways. The main obstacles to driving in foggy weather are low visibility and the illusion of visual distance. Under severe weather conditions such as heavy fog, motor vehicle drivers are very likely to encounter unexpected situations during driving, which may cause traffic accidents, and even cause local traffic paralysis. Casualties and other dire consequences. In order to solve the problem of driving safety on high...
