Problems solved by technology

The current traffic system mainly uses induction coils, video surveillance, geomagnetic detection and other means to collect traffic information. This method is susceptible to interference from weather and other factors, and lacks the ability, timeliness, and authenticity of all-weather real-time traffic data collection. , the stability needs to be improved
Second, the collected data is relatively single. It can only perceive the passing situation of vehicles and the monitoring screen of the road network and other original data with single attributes, which are difficult to extract and process. Further processing of digital information, it is impossible to carry out digital, informatization, and intelligent management of traffic and vehicles in the true sense; therefore, it is urgent to develop a high-performance safe driving system

Embodiment 1

[0028] Example 1: Such as figure 1 with figure 2 As shown, the present invention is a safe driving system based on an electronic license plate. After the system is activated, first, the road environment perception system collects current road information in real time through the RFID reader set in the electronic license plate, such as road type, speed limit, number of lanes and roads. The contents of the signs and signs are written into the central processing unit; the vehicle condition information collection system is based on the RFID reader in the electronic license plate and the electronic tag in the electronic license plate, and achieves the voltage by controlling the matching of the antenna impedance and the impedance of the electronic tag chip Amplitude modulation, using RFID dynamic interactive communication to collect the running status of the front and rear vehicles, such as speed, distance between vehicles, acceleration and other information, including the current ve...

Embodiment 2

[0032] In the above embodiment, the electronic tag inside the electronic license plate uses UHF electronic tags, and the RFID reader is a UHF reader; UHF electronic tag active positioning technology has long recognition distance, low power consumption, low cost, large memory capacity, Significant advantages such as high safety; not only on highways, this system will receive better results, and it is also applicable to urban roads with low traffic volume and ice and snow roads. The entire system uses the existing vehicle-mounted electronic license plate to dynamically detect the distance between the vehicles, and the non-contact transmission of energy based on the principle of electromagnetic coupling between the RFID reader and the electronic tag, combined with the UHF wireless orientation algorithm, and the adjacent lane collision avoidance algorithm to detect the front and rear, left and right vehicles in real time. If the distance between the two is within a safe distance, re...

Abstract

The invention discloses a safe driving system and method based on an electronic license plate. According to the driving method, unique bi-directional interactive mapping from a physical space to an information space of vehicles is realized by perceiving and feeding back the current road-concerned information, operating condition information of the vehicles around a current lane and driving state information of the current vehicles in real time. Real-time driving change strategies are provided for drivers to effectively prevent the occurrence of road traffic accidents.

Description

Technical field [0001] The invention relates to the technical field of automobiles, in particular to a safe driving system and a driving method based on an electronic license plate. Background technique [0002] According to relevant statistics, collisions and rear-end collisions account for the largest number of road traffic accidents. Investigation and analysis also show that the cause of most collisions and rear-end collisions is that the distance between two adjacent vehicles is smaller than the safe distance. The current traffic system mainly uses induction coils, video surveillance, geomagnetic detection and other means to collect traffic information. This method is vulnerable to weather and other factors and lacks the ability to collect traffic data in real time all-weather, timeliness, and authenticity. , Stability needs to be improved. Secondly, the collected data is relatively simple, and can only perceive the raw data with single attributes, such as the passage of ve...
