重型车辆本身特点导致其侧倾稳定性较差,极易发生侧翻事故,为此必须提高车辆主动安全性、操纵稳定性和车辆侧翻预警技术,从而减少重大交通事故发生几率,保证公路运输安全。在全面阐述国内外车辆侧翻预警方法及研究现状的基础上,指出现有研究方法存在的问题,最后介绍了隐马尔可夫理论和车路协同2种侧翻预警关键技术及发展趋势。
Heavy vehicle has very poor roll stability,causing many tumbling accidents.And the active safety performance,handling and stability performance and side tumbling pre-warning technology of heavy vehicle must be improved to reduce the probability of serious traffic accidents and ensure the safety of road transportation.In the paper,the methods of side tumbling pre-warning and research status at domestic and abroad are discussed,and problems of present research are pointed out.The hidden Markov theory and the vehicle-road collaborative method are also introduced as two key techniques and development trend of side tumbling pre-warning method.
