Abstract

The invention discloses a method and device for determining the risk level of lane-changing behavior of a smart vehicle, which defines the risk level of comprehensively evaluating the lane-changing behavior of a smart vehicle from safety indicators, high-efficiency indicators and comfort indicators; The comprehensive evaluation index of lane-changing behavior risk of vehicles that are within the communication range of the target vehicle before and after the lane; according to the historical data percentage division of the comprehensive evaluation index of vehicle lane-changing behavior risk, determine the corresponding risk level of the current comprehensive evaluation index under the two databases , and then determine the current risk level of the target vehicle's lane-changing behavior. The present invention comprehensively considers the interaction between the lane-changing vehicle and all vehicles within the traffic range, uses the historical data of the lane-changing vehicle to evaluate the lane-changing risk of the target vehicle, and evaluates the risk level of the lane-changing behavior more comprehensively and accurately. Provide scientific and reasonable basis for judgment and decision-making, and provide guarantee for road traffic safety and driving efficiency.

Description

technical field [0001] The invention relates to the field of intelligent traffic control, in particular to a method and device for determining the risk level of lane-changing behavior of an intelligent vehicle. Background technique [0002] With the breakthrough and continuous advancement of core technologies in the fields of computers, vehicle engineering, and wireless communications, intelligent networked vehicles and unmanned vehicles, as the future development direction of automobiles, have a profound impact on the automobile industry and the transportation industry. Under the strategic background of "Traffic Power", scientific researchers continue to achieve breakthroughs in technology, and constantly improve various performance indicators of smart vehicles, so that road traffic safety and traffic efficiency are continuously improved. [0003] In non-intersection road sections, the driving direction of the vehicle is generally divided into lateral lane change and longit...
