Novel vehicle speed early warning system

Abstract

The invention discloses a novel vehicle speed early warning system, which comprises a vehicle monitoring module, a data management module, a road condition detection module, a map information memory,a safe vehicle speed database and a safe speed analysis module, wherein the vehicle monitoring module is used for detecting the vehicle speed, the position, the vehicle flow and the driving trajectoryand transmitting the above information to the data management module; the data management module transmits the vehicle position and the driving trajectory to the road condition detection module and transmits the vehicle speed and the vehicle flow to the safe speed analysis module; the road condition detection module acquires the pavement parameter information in front of the road according to thevehicle position and the driving trajectory and transmits the information to the safe speed analysis module; and the safe speed analysis module analyzes the current vehicle speed and the vehicle flowand transmits the result to a vehicle-mounted terminal, and the vehicle-mounted terminal makes a voice prompt. In combination of the vehicle speed, the driving trajectory, the position and the vehicle flow condition, the safe vehicle driving speed is analyzed, and the probability of traffic accidents is reduced.

Description

technical field [0001] The invention belongs to the technical field of road vehicle speed safety driving, and relates to a novel vehicle speed early warning system. Background technique [0002] With the increase of vehicle size and speed, especially commercial vehicles, which have heavy weight, long wheelbase and high center of mass, accidents are prone to occur on mountainous roads with many curves and long downhill roads. The main causes of accidents are mostly overspeed and brake failure ;Many mountain roads are old, and the early design can no longer meet the safety needs of modern commercial vehicles. The speed limit signs are not intuitive and real-time for commercial vehicles, which affects the safe driving of commercial vehicles on mountain roads. [0003] The driving speed of the vehicle is an important proof of the efficiency of the vehicle movement and the safety of the vehicle. The current driving speed limit of the vehicle mostly follows the speed limit of the ...

[0002] With the increase of vehicle size and speed, especially commercial vehicles, which have heavy weight, long wheelbase and high center of mass, accidents are prone to occur on mountainous roads with many curves and long downhill roads. The main causes of accidents are mostly overspeed and brake failure ;Many mountainous roads have a long history, and the early design can no longer meet the safety requirements of modern commercial vehicles. The speed limit signs are not intuitive and real-time for commercial vehicles, which affects the safe driving of commercial vehicles on mountainous roads

[0003] The driving speed of the vehicle is an important proof of the efficiency of the vehicle movement and the safety of the vehicle. The current driving speed limit of the vehicle mostly follows the speed limit of the road speed limit plate, that is, the speed limit requirement given by the traffic department. At present, in order to reduce the driving time, the driver usually Speeding in unmonitored areas, due to unfamiliar road conditions and insufficient driving experience of drivers, can easily cause traffic accidents on special road sections. Rear-end collision with the rear car will cause traffic jams. If the speed is fast, the top of the ramp will easily collide with the opposite vehicle due to the limited sight of the driver, causing casualties; for curved roads, if the speed is fast, it will The driver's reaction speed is slow and the stability of the body is poor, and the vehicle drifts, and even causes the vehicle to roll over, crash into the guardrail, and violently collide with passing vehicles, causing casualties and property losses. In order to improve the safety of drivers and passengers, To reduce the probability of traffic accidents, it is necessary to design a new speed warning system

[0004] For example, Chinese patent (CN201710812900.X) provides a vehicle speed warning system based on road conditions. The system detects the vehicle's location, driving track and vehicle speed information through a vehicle parameter detection module. The vehicle parameter detection module includes positioning Unit, speed detection unit and driving trajectory determination unit, the positioning unit is GPS positioning, used to obtain the position information of the vehicle, and send the position information of the vehicle to the map information storage; the speed detection unit is a speed sensor, installed on the vehicle, used It is used to detect the speed of the vehicle; the driving trajectory determination unit is connected with the positioning unit to determine the trajectory of the vehicle, and then determine the driving vehicle of the vehicle, but there are problems of complex structure and inaccurate measurement accuracy
