车辆安全行驶动态仿真模型及应用研究

Application Study of the Dynamic Simulating Model in Vehicle traveling

针对智能车主动安全系统中安全建模、实时求解等问题,根据车辆行驶速度与车距两个重要的安全因素,将汽车安全行驶的及时感知(检测)和处理(驾驶)分解为与速度相关的时间量,提出了汽车安全行驶仿真动态模型P2OT(环境感知、决策、驾驶操作、汽车行驶)及其时间表达式。应用分析及实验结果说明本文所讨论方法是可行的,具有实际应用价值。

Aimed at the issues on the active safety system of intelligent automobile such as safety-modeling and real-time solution, automobile抯 safe-traveling is actually perception (detection) and processing (steering) in time, which is based on the important factors during the automobile抯 traveling; the speed and distance between automobiles. In the paper, the perception and operation in time for automobile safe-traveling are represented by variable of time related to speed. Also, P2OT (perception, policy, operation, Traveling) and its expression of time are introduced in the paper. The results of the analyses and experiments show that the methods discussed in the paper are feasible and valuable practically.
