Problems solved by technology

However, the current safety distance warning system used in automobiles can only obtain the distance between the current vehicle and the front and rear vehicles. On the expressway, it is also necessary to adjust the speed and safety distance of the current vehicle according to the driving conditions of the front and rear vehicles. The existing safety distance warning system cannot meet such needs

Abstract

The invention discloses a vehicle following safety distance intelligent alarm system, which not only can give an alarm to a driver through a voice alarm module according to the speed of the vehicle and the distance between a front vehicle and a rear vehicle, but also can monitor the speed of the front vehicle and the distance between the front vehicle and the rear vehicle and the speed of the rearvehicle and the distance between the front vehicle and the rear vehicle in real time to further give an alarm to the driver. A driver can conveniently adjust the driving speed or change lanes; a warning vehicle distance threshold value corresponding to the vehicle speed parameter is stored and updated through a vehicle distance threshold value database, and a voice warning content corresponding to the dangerous vehicle and the vehicle distance threshold value is stored and updated through the warning voice database, so that the warning diversity is improved, and real-time updating is facilitated; and a millimeter wave radar set can achieve large-area coverage of monitoring of the side area of a vehicle running at a high speed to guarantee that the side of the vehicle and the front and rear portions of the vehicle side can still be monitored when the vehicle runs at the high speed, and a driver is safer during lane changing and doubling.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to an intelligent alarm system for vehicle following safety distance. Background technique [0002] With the increasing number of automobiles in my country and the rapid development of road construction, while automobiles provide people with convenience for travel, the safety of automobiles has also attracted more and more attention. Collision is a kind of common traffic accident, and its result is ranging from car damage to serious casualties, especially the traffic accidents of multi-vehicle rear-end collision and serial collision on the expressway, the scene is even more tragic. [0003] In the car-following situation, since the following vehicle needs to maintain a relatively consistent speed change and safe following distance with the vehicle in front, ideally, the driver of the rear vehicle should respond to the short-term speed of the vehicle in front in the...
