Embodiment Construction

[0062] Based on the present embodiment, the intelligent vehicle regionalization 5G and Beidou Satellite System warning synergistic interaction techniques hedge, shown in Figure 1, comprising:

[0063] A step, Beidou satellite positioning system to obtain specific information on vehicle speed and vehicle position coordinates, and determines whether the vehicle speed meets the system requirements;

[0064] Step eleven, Beidou satellite positioning system position coordinates acquired vehicle, the preceding vehicle speed and the vehicle speed, if the vehicle speed is less than 20km / h not meet the system requirements, if the vehicle speed is greater than equal to 20km / h in the normal running state for use in the present system;

[0065] Step two, the collected system-conform preceding vehicle and the vehicle speed information of the vehicle into the formula to obtain critical safe distance between vehicles;

[0066] Step di-, collected before and after use of the two vehicle speed...

Abstract

An interactive system and method for regionalized vehicle coordinated early warning and avoidance, belonging to the technical field of multi-vehicle coordination and vehicle avoidance scheduling. The invention solves the problem that the existing method cannot provide early warning for serial rear-end collisions. The vehicle speed condition is judged before the operation of the present invention, so as to ensure the safety monitoring in the normal driving state of the vehicle. Combined with the judgment of whether the rear-end vehicle in front is in the system, according to different situations, different warning and avoidance schemes are selected, which is adaptive. In addition, a feedback link is added. After a limited feedback period, the coordinates of dangerous vehicles and unfeedback vehicles are integrated, a certain warning range is defined, and information about dangerous vehicles is sent to vehicles within the range again to further avoid accidental rear-end collisions. The invention can be used for early warning of serial rear-end collisions of vehicles.

Description

Technical field [0001] The present invention is a multi-car, and cooperative scheduling BACKGROUND hedging vehicle, particularly relates to a system and method for interactive synergistic regionalized vehicle warning hedge. Background technique [0002] With the rapid increase in car ownership, economic losses and casualties caused by traffic accidents and more serious problem, which rear-end accidents accounted for 70% of the total traffic accidents in my country, because of which the front is not timely avoid incidents caused chain rear-end accident is accounted for 34% of them. Up to now, our country intelligent vehicles commonly ranging method will always encounter some problems in practical application. The ultrasonic propagation velocity is slow, susceptible to ambient temperature, interfering factors, the car at high speed, can not keep up with changes in real time ultrasonic ranging vehicle distance measurement accuracy is poor; microwave radar ranging radar signal interf...
