汽车主动安全预警系统警告触发方式研究

Research on Methods of Warning Trigger for Vehicle Active Safety Warning System

确定了汽车主动安全预警系统基于听觉、视觉和触觉为主的警告触发研究策略,在模拟驾驶环境中,分析比较了单一或组合的警告触发方式对驾驶人员操作行为的影响。通过驾驶人员主观判断筛选出适合作为警告触发方式的方案,并借助开发的车道偏离预警系统实际获取不同警告触发方式下驾驶人员的响应时间。对不同警告触发方式下驾驶人员操作的正确人数、平均响应时间和方差三者统计分析,确定听觉和视觉的组合警告更适合作为中国驾驶人员的警告触发方式。

Warning trigger research strategy of vehicle active safety warning system based on auditory, visual and haptic was established. In simulated driving environment, different influences for driver＇s manipulative behavior were compared under single and combined methods, and a suitable warning trigger strategy is selected according to driver＇s subjective judgment. Driver＇s response time was obtained through lane departure warning system experiment. Finally, statistical analysis is made to correct number of operator, average response time and variance under different warning trigger method, identified that the trigger of a combination of auditory and visual warning is more appropriate for our drivers warned.
