Walking safety light reminding system and method and vehicle

Abstract

The invention belongs to the field of automobile active safety, and discloses a walking safety light reminding system and method and a vehicle. The system comprises an interaction control system and alight projection system; the interaction control system is used for judging whether the vehicle meets a walking safety reminding condition based on a pedestrian-vehicle distance according to pedestrian information in front of the vehicle monitored in real time, if so, a first reminding image used for reminding the vehicle to pay attention to a pedestrian is generated, and if not, a second reminding image used for reminding the pedestrian to pay attention to the vehicle is generated; the light projection system is used for projecting the first reminding image to a road surface in front of thevehicle or projecting the second reminding image to a road surface in front of the pedestrian; wherein the walking safety reminding condition is that the distance L between the pedestrian and the vehicle is greater than a safety distance. Clear walking safety reminding information is transmitted to both the pedestrian and the driver through interactive lamplight, and the traffic efficiency and safety are improved.

Description

technical field [0001] The invention relates to a walking safety light reminder system, method and vehicle, belonging to the field of automobile active safety. Background technique [0002] Traditional car signal lights have early warning functions to ensure driving safety, such as outline, brake reminder, steering reminder, reversing reminder and foggy weather warning, which can basically guarantee driving safety under normal traffic conditions and weather conditions. [0003] As the number of vehicles increases, road conditions become more congested and complex. At present, the car signal lights used to indicate the abnormal state of the car or the change of the driving state mainly include the yellow hazard warning signal light and the red light emergency brake light, which can refer to "vehicle abnormality", "poor visibility condition, driving slowly and cautiously" However, due to the relatively single form of expression, only the color of the light is used to distingu...

Problems solved by technology

However, laws and regulations urge drivers to "give way to others", but most pedestrians are still stuck in the concept of "giving way to others", resulting in pedestrians not realizing that they are going to pass when vehicles are giving way, and both sides are giving way to each other Not moving, seriously affecting traffic efficiency

At present, drivers generally pass signals to pedestrians to give way through gestures and eye contact. The overall traffic efficiency is low, and there are situations where other vehicles side by side rush ahead, which poses a greater safety hazard.

Moreover, future unmanned vehicles must have the ability to actively transmit the "vehicle to man" signal before they can drive normally on the road, otherwise it will lead to traffic chaos and accidents
