Safety vehicle distance alarming system based on road environment

Abstract

The invention discloses a safety vehicle distance alarming system based on the road environment. The safety vehicle distance alarming system comprises a weather condition detection module, an image acquisition module, an environmental analysis module, a vehicle speed detection module, a vehicle distance detection module, a control module and an alarming module. The environmental analysis module isconnected with the weather condition detection module and the image acquisition module to judge the road surface where a vehicle travels. The control module is connected with the vehicle speed detection module, the environmental analysis module and the vehicle distance detection module and calculates the relation between the theory safe vehicle distance and the actual vehicle distance according to the received vehicle speed, the vehicle distance and the road surface condition, and if the theory safe vehicle distance is larger than the actual vehicle distance, the control module sends an alarming signal to the alarming module. The road surface where the vehicle travels is detected, the relation between the theory safe vehicle distance and the actual vehicle distance is combined, then alarmreminding is conducted, the road surface environment of vehicle actual travelling is fully considered, the characteristics of fast detection speed and alarming sensitivity are achieved, traffic accidents are reduced, and safety of vehicle driving is improved.

Description

technical field [0001] The invention belongs to the technical field of road traffic, and relates to a safety distance warning system based on road environment. Background technique [0002] In road traffic accidents, the proportion of traffic accidents caused by rear-end collisions during braking is relatively high due to the underestimation of the safe distance between vehicles by drivers, resulting in a large number of property losses and casualties. With the popularity of automobiles, people are constantly pursuing the improvement of automobile safety technology while enjoying the various conveniences brought by automobiles. [0003] For vehicles driving on the expressway, vehicle speed, safety distance, and driver's state are the main hidden dangers of automobile accidents. How to ensure the safe distance between vehicles, vehicles and obstacles during high-speed driving, slow down in time, stop and take corresponding avoidance measures Measures are effective measures t...

AI Technical Summary

Problems solved by technology

The existing vehicle distance safety warning system cannot determine the relationship between the safe vehicle distance and the vehicle speed, and does not take into account the difference of the safe vehicle distance under different road conditions (such as general roads, slippery roads, snow-covered roads, and icy roads). If the safe distance between vehicles is smaller than the actual distance between vehicles, it will cause traffic accidents and seriously endanger the safety of personnel.
