Background
The function of automatic headlight does not include the automatic switch of fog lamp among the present volume production motorcycle type, and the main difficulty is the detection accuracy of the actual weather environment that the fog lamp involves. However, the automatic fog light switch is an obvious attribute that consumers like and can improve the competitive advantage of the vehicle market, the existing V2X technology is still immature, the characteristics of integration of the V2X technology and regional information of an MEC center cannot be relied on, and accurate real-time weather information acquisition cannot be realized, so that the automatic switch function of the fog light is realized. In addition, the existing vehicle-mounted camera is used for detecting weather, so that great deviation occurs and the algorithm difficulty is high, and accurate functional scene identification cannot be really realized.
The term "V2X" as used herein, like B2B, B C, means vehicle to aircraft, i.e., the exchange of information between a vehicle and the outside. The Internet of vehicles establishes a new automobile technology development direction by integrating a Global Positioning System (GPS) navigation technology, an automobile-to-automobile communication technology, a wireless communication technology and a remote sensing technology, and realizes the compatibility of manual driving and automatic driving. In brief, the vehicle model matched with the system can automatically select the driving route with the best road condition through analyzing real-time traffic information in an automatic driving mode, so that traffic jam is greatly relieved. In addition, by using the vehicle-mounted sensor and the camera system, the surrounding environment can be sensed and rapidly adjusted, so that zero traffic accidents are realized. For example, if a pedestrian suddenly appears, it may be automatically decelerated to a safe speed or stopped.
The RSU is an english abbreviation of Road Side Unit, which means a roadside Unit, and is a device that is installed in the roadside in the ETC system, and communicates with an On Board Unit (OBU) by using a DSRC (Dedicated Short Range Communication) technology to realize vehicle identification and electronic deduction. In the management of expressways and parking lots, RSUs are installed on the road sides, and unattended fast special lanes are established. The RSU is designed according to the national standard GB20851, and the communication frequency is 5.8GHz. The RSU consists of a high-gain directional beam control read-write antenna and a radio frequency controller. The high-gain directional beam control read-write antenna is a microwave transceiving module and is responsible for sending/receiving, modulating/demodulating, coding/decoding and encrypting/decrypting signals and data; the radio frequency controller is a module for controlling data transmission and reception and processing information transmission and reception to an upper computer.
In the prior art, chinese invention patent discloses a contextual system for vehicle to all V2X receivers to improve understanding of V2X communication. This patent publication describes embodiments for modifying the operation of vehicle components based on vehicle-to-all V2X communication.
