Embodiment Construction

[0062] The interactive technology of intelligent regionalized vehicle cooperative early warning and risk avoidance based on 5G and Beidou satellite system in this embodiment, as shown in Figure 1, includes:

[0063] Step 1. Use Beidou satellite positioning system to obtain specific information such as vehicle position coordinates and vehicle speed, and judge whether the vehicle speed meets the system requirements;

[0064] Step 11. Use the Beidou satellite positioning system to obtain the vehicle position coordinates, the speed of the vehicle in front and the vehicle speed. If the vehicle speed is less than 20km / h, it does not meet the system requirements. If the vehicle speed is greater than or equal to 20km / h, it is in a normal driving state. , applicable to this system;

[0065] Step 2, bring the speed information of the vehicle in front and the vehicle that meets the system requirements into the formula to calculate the critical safety vehicle distance;

[0066] Step 21, ...

Abstract

The invention discloses a regional vehicle collaborative early warning risk avoiding interaction system and method, which belong to the technical field of multi-vehicle collaboration and vehicle risk avoiding scheduling. The problem that an existing method cannot perform early warning on serial rear-end collision is solved. The vehicle speed condition is judged before operation, and safety monitoring is ensured in the normal driving state of the vehicle. Different early warning avoiding schemes are selected according to different conditions by combining the judgment condition of whether the front rear-end vehicle is in the system, so that the method has self-adaptability. And after a feedback link and limited feedback duration are added, the coordinates of the vehicle in the dangerous state and the coordinates of the vehicle which is not fed back are integrated, a certain early warning range is defined, information of the dangerous vehicle is sent to the vehicles in the range again, and the accidental rear-end collision situation is further avoided. The method can be used for early warning of serial rear-end collision of the vehicle.

Description

technical field [0001] The invention belongs to the technical field of multi-vehicle coordination and vehicle risk avoidance dispatching, and in particular relates to an interactive system and method for regionalized vehicle coordinated early warning and risk avoidance. Background technique [0002] With the rapid increase of car ownership, the economic loss and casualties caused by traffic accidents are becoming more and more serious. Among them, rear-end collision accidents account for 70% of the total traffic accidents in my country, and among them, accidents caused by sudden accidents ahead did not avoid in time Serial rear-end accidents accounted for 34% of them. Up to now, the ranging methods commonly used in my country's intelligent vehicles will always encounter certain problems in practical applications. For example, the propagation speed of ultrasonic waves is slow, and it is easily interfered by factors such as external temperature. When the car is driving at high...
