Abstract

The invention discloses a curve obstacle vehicle filtering method. The method comprises the following steps: 1, acquiring motion parameters of an obstacle vehicle in front of a vehicle; 2, filtering the distance of the obstacle vehicle in front of the vehicle; 3, establishing a running track of the vehicle; 4, determining a lane filtering range according to the running track of the vehicle; 5, judging a lane where the obstacle vehicle is located in a first filtering set W'; 6, carrying out obstacle vehicle collision filtering; and 7, displaying the motion parameters of the obstacle vehicle ina target set W''' through a computer. The method is simple in structure and reasonable in design. Target vehicles with the collision probability are filtered out through the running track of the vehicle, the motion parameters, detected by radar, of the front obstacle vehicle and lane classification. Classification is clear, filtering is rapid, simple and convenient, and the defect that misoperation is caused and precision is reduced due to the fact that the same filtering standard is adopted for the obstacle vehicle is overcome.

Description

technical field [0001] The invention belongs to the technical field of automobile safety, and in particular relates to a method for filtering vehicles with curve road obstacles. Background technique [0002] With the blowout development of China's motor vehicle ownership in the past ten years, the problem of road traffic safety has become increasingly prominent. According to the report of the United Nations Road Safety Collaborative Mechanism released by the Secretary-General of the United Nations, Ban Ki-moon, traffic accidents in the world cause nearly 1.3 million deaths and 20 to 50 million injuries every year. Traffic accidents on curves account for a large proportion, limited vision for driving on curves, insufficient information interaction between vehicles, rear-end collisions, rollovers, lane departures and other accidents occur frequently. [0003] How to ensure the safety of automobile driving is the primary issue of travel. For the vehicle controlled by the driv...
