Embodiment Construction
[0024] The present invention will be further described below in conjunction with the description of the drawings and specific embodiments.
[0025] Such as figure 1 As shown, the overtaking operation is divided into three steps: lane change, vehicle overtaking, and returning to the original lane. The present invention provides an optimal autonomous overtaking control method based on driving characteristic analysis. For left overtaking, a method based on abnormal driving is proposed Optimal overtaking strategy for detection. The fuzzy inference system (Fuzzy Inference System, FIS) is used to analyze the driving characteristics of the preceding vehicle, and then the specific driving types output by it are simplified, that is, the two states of danger and safety. Under the condition of minimizing the cost, the following vehicle selects corresponding strategies according to the state of the preceding vehicle, such as car-following, accelerating and overtaking. This method can pr...

The invention provides an optimal autonomous overtaking control method based on the driving characteristics analysis. The method includes the following steps that 1, a fuzzy inference system (FIS) isused for driving characteristic analysis of a front vehicle, and the specific driving types, namely the danger state and the safety state, output by the system are simplified; according to the drivingbehavior of the front vehicle, a rear vehicle selects a corresponding strategy, and optimal autonomous overtaking control is conducted. The method has the advantages that original overtaking controlis relatively complicated, and the simplified binary driving characteristics can reduce the difficulty of overtaking control. The optimal control mode of a binary overtaking strategy can provide a safe, efficient and low-consumption optimal strategy for the left-side surpassing stage in the autonomous overtaking process.
Description
technical field [0001] The invention relates to an overtaking control method, in particular to an optimal autonomous overtaking control method based on driving characteristic analysis. Background technique [0002] In recent years, as sensor technology, information processing and computer technology have become more and more mature, Intelligent Transportation System (ITS) has also developed rapidly, bringing huge economic benefits to the society. The main areas of intelligent transportation systems include accident prevention and mitigation, safety issues, reduction of greenhouse gas emissions, and improvement of energy and infrastructure utilization efficiency, among which safety issues have always been one of the hot issues that people have paid attention to. Statistics show that 1.2 million people die in traffic accidents every year. If no measures are taken, it is expected that the number of traffic accidents will continue to increase by 2020. Among them, traffic acciden...
