Vehicle highway safety warning device and method

Abstract

The invention discloses a vehicle highway safety warning device and method, which are mainly applied to highway driving. The warning device comprises a positioning module, a distance analysis module and a warning module. The positioning module is used for acquiring the current location information of a vehicle. The distance analysis module acquires the speed of the highway according to the location information of the vehicle, and calculates the minimum safety distance. The warning module is used for warning the vehicles behind. An appropriate mode is chosen on the warning module according to the driver's judgment on the current state of the vehicle. Then, the mode is fed back to the positioning module and the distance analysis module, the positioning module transmits the location and otherinformation to the distance analysis module, the distance analysis module calculates the minimum safety distance according to the current speed and the information obtained by the positioning moduleand transmits the minimum safety distance to the warning module, and the warning module receives the information of the distance analysis module and sends warning information to the vehicles in the same direction. Therefore, the driving safety of vehicles is ensured, and accidents are avoided.

Description

technical field [0001] The invention relates to the field of traffic signal control, in particular to a vehicle high-speed safety early warning device and method. Background technique [0002] With the development of China's economy and automobile industry, automobiles have gradually become a means of transportation and entered thousands of households. Especially now that China's highways extend in all directions, people can drive anywhere, existing navigators, mobile terminals equipped with navigation software, driving recorders and other navigation equipment can assist the driver during the driving process and reduce the risk of accidents. occur. General navigation equipment has basic GPS positioning, route planning, vehicle speeding reminder, etc., but the speed of the vehicle is different in different environments. If the driver cannot adjust the speed according to the real-time situation, there will be certain safety hazards , especially for vehicles traveling on high...

Problems solved by technology

General navigation equipment has basic GPS positioning, route planning, vehicle speeding reminder, etc., but the speed of the vehicle is different in different environments. If the driver cannot adjust the speed according to the real-time situation, there will be certain safety hazards , especially for vehicles traveling on highways

[0003] There are restrictions on the speed of vehicles on the expressway, both the minimum speed and the maximum speed. If there is an accident ahead, if there is no timely warning to the vehicles behind, it is easy to cause accidents such as vehicle rear-end collisions, resulting in personal injury; or The vehicle cannot move forward due to a problem. The existing method is to place a warning sign behind the vehicle, but the warning sign is placed too close, and it is difficult for the rear vehicle traveling at high speed to respond in such a short time, so it is easy to cause a safety accident. , if not handled properly, it will cause continuous collisions and lead to tragedy
