Embodiment

[0047] This embodiment first provides a driving safety monitoring device and method based on BSM information fusion of the Internet of Vehicles. The specific architecture of the device and method is as follows figure 1 As shown, it includes data acquisition layer, network communication layer, scene analysis layer and application service layer.

[0048] The data acquisition layer can realize the comprehensive acquisition of information such as vehicle motion status, driving operation status, and road traffic environment, and form a standard SAE J2735 Internet of Vehicles BSM data set to provide basic data for the system to predict collisions.

[0049] Such as figure 1 As shown, the status information of the own vehicle and adjacent vehicles is obtained through the vehicle-mounted OBE interface and vehicle-to-vehicle communication.

[0050] The collection of vehicle status information is the basis for the IoV system to perceive driving safety. The data of TCP / IP and Bluetooth ...

Abstract

The invention relates to a driving safety monitoring device and method based on car networking BSM (Basic Safety Message) information fusion and belongs to the technical field of intelligent vehicles.According to the method, on the basis of safety pre-warning of a traditional vehicle and a special vehicle, a driving safety monitoring device and method based on car networking BSM information fusion are provided, a variable precision rough set and an information entropy measuring algorithm are combined, the collision risk degree in the driving process of a general vehicle or a special vehicle is judged, and real-time pre-warning is carried out. According to the device and the method in the invention, vehicle safety operation influence factors of multiple aspects of people, vehicles and roads are fully considered, thereby improving the accuracy of collision risk identification in a complex road traffic environment. The device and the method in the invention are high in calculation speed,can meet a functional requirement for real-time pre-warning, and can be widely applied to anti-collision pre-warning and safe driving auxiliary systems and driving simulation platforms of various vehicles (including special vehicles) for evaluation and prediction.

Description

technical field [0001] The invention relates to a device and method for assisting driving of a connected car, which belongs to the technical field of intelligent vehicles, and in particular relates to a driving safety monitoring device and method based on BSM information fusion of the connected car. Background technique [0002] In recent years, with the rapid increase of the domestic car ownership rate, the situation of road traffic safety has become increasingly severe. At the same time, with the rapid development of mobile Internet technology and electronic information technology, people hope to use advanced communication technology, computer technology and sensor technology to improve transportation efficiency, reduce traffic safety accidents, and improve driving experience. [0003] Traditional methods are generally based on infrared, radar, camera and other sensors for vehicle collision avoidance warning devices, which use the information obtained from the sensors to c...
