The invention discloses a speed limit system for expressway vehicle driving in haze weather. The speed limit system comprises a first computer disposed at an expressway entrance, a second computer disposed at an expressway exit and a signal processing unit disposed on a driving vehicle. The signal processing unit is respectively in wireless communication connection with the first computer and the second computer. The signal processing unit is also respectively connected with a speed limit device disposed on the driving vehicle and a display screen disposed in a cab of the driving vehicle. The speed limit device is connected with an accelerator and a brake of the driving vehicle. According to the speed limit system for expressway vehicle driving in haze weather, the signal processing unit is respectively in wireless communication connection with the first computer and the second computer, the speed of the vehicle driving in the expressway is controlled, the requirement of the expressway for speed limit is met, the problem that accidents are caused on expressways due to speeding in haze weather when visibility is low can be effectively resolved, and reliability is high.
Description
technical field [0001] The invention relates to a speed-limiting system, in particular to a speed-limiting system for highway vehicles in haze weather. Background technique [0002] In recent years, with more and more private cars, people pay more and more attention to the safety of driving. And along with the deterioration of air quality, smog weather phenomenon increases, and harm increases the weight of. According to the "Regulations for the Implementation of the Road Traffic Safety Law": "When the expressway encounters low-visibility weather conditions such as fog, rain, snow, sand, and hail, and the visibility is less than 200 meters, the driver should turn on the fog lamps, dipped beams, and warning lights. When the visibility is less than 100 meters, turn on the fog lights, low beam lights, position lights, front and rear position lights and hazard lights. Alarm flashing lights, the speed must not exceed 40 kilometers per hour, and keep a distance of more than 50 me...
