Event data recorder provided with signal lamps for reminding other vehicles and control method of event data recorder

Abstract

The invention discloses an event data recorder provided with signal lamps for reminding other vehicles and a control method of the event data recorder. The recorder is used on an n oversize vehicle and comprises an image based zebra crossing identification module and a physical isolation belt isolated non-motor vehicle road identification module which are embedded into a host. The event data recorder is characterized in that one output end of a CPU (central processing unit) is sequentially connected with a left side lamp on-off control module and a left side pedestrian signal lamp in series, and the other output end is sequentially connected with a right side lamp on-off control module and a right side pedestrian signal lamp in series; an image based module for identifying whether a pedestrian exists at the zebra crossing and identifying the pedestrian movement behavior and trend in a sectional manner is further embedded into the host; and the left and right slide pedestrian signal lamps are used for catching attention of vehicles on the left side and the right side of the vehicle respectively. The movement direction of pedestrians on a zebra crossing vision dead zone produced by the vehicle body is reminded, so that when the oversize vehicle slows down or stops to give way before the zebra crossing, traffic accidents caused when other vehicles on the same side road ways on the left side or the right side pass by the zebra crossing are reduced.

Description

technical field [0001] The present invention relates to the field of traffic safety on road pedestrian crossings (zebra crossings), in particular to a traffic recorder with a signal lamp to prompt other vehicles and a control method thereof. ), when the video detects pedestrians on the pedestrian crossing (zebra crossing) ahead, it will remind other vehicles in the left and right lanes in the same direction in the form of external signal lights to pay attention to the driving safety of the pedestrian crossing (zebra crossing). 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...

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)
