为了客观量化评价驾驶人驾驶熟练程度,分析了实车试验环境中的眼动仪采集数据。采取注视区域划分方法,选取8个注视转移模式表征参数作为评价指标。运用主成分分析方法研究了15个驾驶人眼动数据,得到了基于注视转移模式的驾驶熟练程度计算方法。试验结果表明:15个驾驶人驾驶熟练程度评价得分值与其驾驶经验里程之间存在密切关系;运用提出的方法,可以清楚区分以5.0×10~4 km驾驶经验里程为界限的2个群体,但是在每个群体内部,驾驶人驾驶熟练程度评价得分不呈现明显的规律性。
In order to objectively evaluate the proficiency of driver’s driving, the data of eye tracker in real vehicle test environment was analyzed. Taking the method of gazing area division, eight ghosting transfer mode characterization parameters were selected as the evaluation index. The principal component analysis method was used to study the eye movement data of 15 drivers and the driving proficiency calculation method based on gaze transfer model was obtained. The test results show that there is a close relationship between the driving proficiency score and driving experience mileage of 15 drivers. By using the proposed method, two groups whose driving experience mileage is 5.0 × 10 ~ 4 km can be clearly distinguished, However, within each group, driver proficiency evaluation scores showed no obvious regularity.
