摘要
为设计适合于驾驶员不同疲劳状态的防撞报警算法,利用驾驶模拟器分析了驾驶员处于不同疲劳状态时常用报警算法的实际效果和对交通危险感知的变化。结果表明,随着疲劳程度的加深,防撞报警算法须适当提前报警时机,且该时机应符合驾驶员在不同疲劳状态下对交通危险的感知特性。在此基础上,构建了适应疲劳状态的防撞报警算法,实验验证的结果表明:该算法能为不同疲劳状态的驾驶员提供合适的报警时机,提高了实际的防撞报警效果。
For designing a collision warning algorithm adapting to driver＇s different drowsiness levels,the practical effects of some common algorithms and the changes in traffic risk perception for drivers at different drowsiness states are analyzed with driving simulator.The results show that with the increase in driver＇s drowsiness level,the warning timing should be reasonably advanced and should accord with the traffic risk perception of driver at different drowsiness states.On this basis a new collision warning algorithm adapting to driver drowsiness is established and the results of experimental validation indicate that the algorithm created can provide proper warning timing for drivers at different drowsiness states,enhancing the practical effects of collision warning.
