摘要
为了考虑个性化的驾驶员特性对AEB控制策略的影响,提出了一种基于不同驾驶员驾驶风格的AEB控制策略。根据AEB危险场景下的驾驶员反应时间和情境风险度评价得分提出了驾驶风格识别系数的评价指标,通过驾驶员特性所呈现的人群聚类规律,将驾驶员分为谨慎型、普通型和激进型,同时引入危险系数来分级控制安全距离模型的制动减速度,完成紧急状况下的车辆制动。Simulink与Trucksim联合仿真结果表明,不同驾驶风格驾驶员对AEB系统介入时机与最小安全距离的心理预期具有不同的个性化需求,基于不同驾驶风格的AEB控制策略可以有效改善AEB系统的适应性,提高驾驶员的舒适性。
In order to consider the influence of personalized driver characteristics on AEB control strategy,this paper proposes an AEB control strategy based on different driver driving styles.According to the driver reaction time and situational risk evaluation score under AEB danger scenario,the paper proposes the evaluation index of driving style identification coefficient.And according to the clustering rule of drivers,drivers are divided into 3 types of driving styles,namely cautious type,ordinary type and aggressive type.At the same time,the danger coefficient is introduced to control the braking deceleration of the safety distance model in different levels,and brake the vehicle in emergency.Co-simulation of Simulink and Trucksim shows that drivers with different driving styles have different personalized demands on the psychological expectation of AEB system intervention timing and minimum safe distance,and AEB control strategies based on different driving styles can effectively improve the adaptability of AEB system and improve drivers’comfort.
