前向碰撞预警系统报警策略分析
|
摘要
依据前向碰撞预警系统工作原理,对感知传感器的性能对比分析,分析FCW系统报警逻辑和报警形式,驾驶风格特性,以及报警时机和最低车速;同时,从视觉、听觉、触觉三种报警方式结合驾驶员主观感受分析。得出前向碰撞预警系统感知传感器的选型建议,得出报警逻辑方面应根据不同的交通环境和车速设定对应的报警形式;为适应不同驾驶风格需求设定3种级别的报警时机选项,并根据人类对报警的响应和可接受度,为不同的报警形式提供差异化的报警方式。为FCW系统的设计提供客观有效的参考,在确保FCW系统性能的同时,提升驾驶员对于FCW系统的可接受度。
According to the working principle of the forward collision warning system, the performance comparison analysis of the sensor is performed. Analyze FCW system alarm logic and alarm patterns, driving style characteristics, as well as alarm timing and minimum speed.At the same time, from the three modes of visual, auditory and tactile, combined with the subjective feeling analysis of the driver. Derived the selection recommendation of the sensor for the forward collision warning system, The alarm logic should be set according to different traffic environment and vehicle speed. Three levels of alarm timing options are set to suit different driving style requirements, and differentiated alarm modes are provided for different alarm forms based on human response and acceptability to alarms. Provide an objective and effective reference for the design of the FCW system to improve the acceptability of the FCW system while ensuring the performance of the FCW system.
