Embodiment 1

[0031] like figure 2 As shown, this embodiment is realized through the following steps:

[0032] Step 1, data collection stage. During the driving process of the vehicle, there may be various behaviors such as acceleration, deceleration, change of direction, and U-turn, and these behaviors are largely random. turn signal etc. And the present invention, because mobile terminal is configured in front of automobile, thereby these behaviors can be judged well (because current mobile terminal all carries various sensors, as acceleration sensor, direction sensor etc.), so can be very good Identify some common driving operations. When the vehicle-mounted system has an open interface, the data source can also directly call the corresponding API of the vehicle-mounted system to obtain (such as acceleration, deceleration, steering, engine speed, etc.), and the above is the collection of data.

[0033] Step 2, the data encoding stage, that is, the data is encoded correspondingly by ...

Abstract

A vehicle safety control method and system based on an LED visible light communication technology. During a driving process, a vehicle can encode (based on LED) current vehicle information (vehicle model, length, width, height, etc.) and driving situations (steering, acceleration and brake) and then performs transmission through a signal transmitting device such as a taillight (LED light) or an LED panel (arranged at the rear side of the vehicle and capable of transmitting LED visible light) by a visible light communication technology; during a driving process, a rear vehicle can receive an LED signal through an LED signal receiving device (smart phone), then accurately decodes the corresponding information and simultaneously displays the information to a user or performs vehicle early warning (prompting brake information and so on). The user can know information of the front vehicle and corresponding driving situation of the front vehicle through the information received by the smart phone, thus the user can prepare for some emergency events in advance, thereby avoiding traffic accidents caused by situations such as a sudden brake and a sudden steering.

Description

technical field [0001] The present invention relates to a technology in the field of optical communication, in particular to a vehicle safety control method and system that utilizes low-cost ordinary LEDs and mobile terminals to realize active safety information alarms between front and rear vehicles and vehicle visibility distance monitoring . Background technique [0002] Since the second half of the 21st century, the automobile industry, which condenses human civilization, has developed rapidly. As the main means of transportation in modern times, automobiles bring convenience to people's work and life. However, with the continuous increase of motor vehicles, the number of traffic accidents tends to increase. According to the statistics of the World Health Organization, traffic accidents have become one of the ten major causes of death in the world. [0003] Studies have shown that most of the traffic accidents are caused by human factors, such as sudden braking, sharp...
