Large vehicle right turning safety early-warning system

Abstract

The invention relates to a large vehicle right turning safety early-warning system, which comprises four modules such as a recognition module, an induction module, an information processing module and an early warning module, and is characterized in that the recognition module recognizes the vehicle model and a serial number of a large right turning vehicle getting into a detection area and a serial number of a non-motor vehicle; the induction module detects the speed and position of the large vehicle and the non-motor vehicle and calculates a horizontal distance of the large vehicle and the non-motor vehicle; the information processing module calculates a safe distance by using the detected speed of the large vehicle, calculates the inner wheel difference by using the recognized vehicle model information, compares the safe distance with a real-time distance and judges a potential dangerous non-motor vehicle; and the early warning module sends an alarm in allusion to the dangerous individual. Early warning is performed in allusion to the following two circumstances: early warning is performed when the parallel distance between the non-motor vehicle and the large vehicle is less than the safe distance before the large vehicle turns right; and early warning is performed if the non-motor vehicle is within a range of the right turning inner wheel difference and 1m beyond of the large vehicle while the large vehicle turns right. The large vehicle right turning safety early-warning system can prejudge whether the non-motor vehicle stays at safety threat and give an alarm in a targeted manner, thereby effectively reducing the accident rate and the mortality rate.

Description

technical field [0001] The invention belongs to the field of intelligent traffic management and relates to a right-turn safety early warning system for large vehicles. Background technique [0002] In the prior art, when the car turns right, the track of the right rear wheel is located on the right side of the track of the right front wheel. The greater the curvature of the vehicle's driving curve, the greater the deviation of the trailing track of the rear wheel from the track of the front wheel on the same side, that is, the inner wheel difference will be generated, forming a dangerous area. [0003] Existing vehicle is equipped with rearview mirror on both sides outside the car, so that the road condition of watching vehicle both sides rear. However, the rearview mirror can only reflect the field of view in a specific direction, and the cab is located at a high position, so the driver has a blind spot when observing the road conditions. According to statistics, right-tu...

Problems solved by technology

There are certain defects in the above studies: the first and second types of devices need reaction time after the driver finds danger, and the braking distance of large vehicles is long, which cannot effectively prevent accidents from happening; the lights of the third type of device are not conspicuous enough to play a role. warning effect
