Event data recorder of large vehicle and implementation method thereof

Abstract

The invention discloses an event data recorder of a large vehicle and an implementation method thereof. The event data recorder comprises a camera assembly, a speed sensor, a data memory, a zebra crossing identification module and a zebra crossing pedestrian identification module, wherein the camera assembly, the speed sensor and the data memory are arranged in a host, are connected with a central processing unit and are used for collecting images of roads in front of the vehicle, and the zebra crossing identification module and the zebra crossing pedestrian identification module are embedded in the central processing unit and are based on the images. The event data recorder is characterized in that one output end of the central processing unit is sequentially and serially connected with a left lamp switch control module and a left pedestrian signal lamp at the left outside of the vehicle, and the other output end of the central processing unit is sequentially and serially connected with a right lamp switch control module and a right pedestrian signal lamp at the right outside of the vehicle. The event data recorder has the advantages that the left pedestrian signal lamp and the right pedestrian signal lamp are used for respectively alerting the same-direction vehicles at the left and right sides of the vehicle to pay attention to the vehicle body, and providing the prompt that a pedestrian exists in the visual dead zone; when the large vehicle decelerates to slowly drive or stops for giving away before the zebra crossing, the occurrence of traffic accidents is reduced when the other vehicles on the same-direction lanes at the left and right sides, especially small vehicles, go through the zebra crossing.

Description

technical field [0001] The present invention relates to the field of traffic safety on the pedestrian crossing (zebra crossing) of roads, in particular to a driving recorder for large vehicles and its implementation method, which can warn other vehicles when there are pedestrians on the pedestrian crossing (zebra crossing). Driving safety at pedestrian crossings (zebra crossings). Background technique [0002] At present, in order to ensure the smooth flow of the road, most of the pedestrian crossings set on urban block road sections only have the traffic signals of pedestrian crossing lines (zebra crossings) and pedestrian crossing warning signs. If someone rushes out in the direction where the line of sight is blocked, traffic accidents are likely to occur. When the person in the direction where the line of sight is blocked is riding a bicycle, electric vehicle, or tricycle, traffic accidents are more likely to occur. [0003] Although the traffic law stipulates: When a m...

AI Technical Summary

Problems solved by technology

Large vehicles tend to start slowly, so when the green light is on, the driver of a small vehicle in the side lane may think that there is no one on the pedestrian crossing (zebra crossing) and is the first to start first. , traffic accidents may occur, so on a pedestrian crossing line (zebra crossing) with red lights on, traffic accidents may also occur when the vehicle driver has a blind spot for pedestrians on the pedestrian crossing line (zebra crossing)
