The invention discloses an intelligent driver model improvement method based on road driving conditions. The method comprises the following steps: S1, data acquisition; s2, through data screening and processing, historical driving data with following performance on one road in the historical driving data are obtained; s3, a car-following model and a simulation environment for running of the car-following model are constructed in the Matlab through a model formula; s4, inputting the training data screened out in the step S2 into a car-following model, and calibrating parameter values of the car-following model; and S5, substituting the trained and calibrated car-following model parameter values into the car-following model to obtain a car-following model conforming to the actual condition of the current road, and testing and evaluating the effectiveness and superiority of the improved car-following model through the test data obtained in the step S2. The method is an improved model which can be adjusted according to different weather conditions and is based on an intelligent driver model.

    本发明公开了一种基于道路行车条件的智能驾驶员模型改进方法,包括如下步骤:S1、数据采集;S2、通过数据筛选和处理,得到历史行车数据中一条道路上具有跟随行性的历史行车数据;S3、在Matlab中通过模型公式构建出跟驰模型以及跟驰模型运行的仿真环境;S4、将步骤S2中筛选出的训练数据输入至跟驰模型中,标定跟驰模型的参数值;S5、将训练好后的标定的跟驰模型参数值代入跟驰模型中,得到与当前道路实际情况相符的跟驰模型,并通过步骤S2得到的测试数据,测试与评估改进后的跟驰模型的有效性和优越性。该方法是一个能够针对不同的天气状况进行调整的基于智能驾驶员模型的改进模型。
