摘要：为提高商用车车道偏离预警（lane departure warning,LDW）系统的有效性和合理性，根据商用车的质量、结构、控制等特点，选取车辆质量和纵向速度2个变量设计商用车LDW决策处理系统；基于模糊控制理论对车辆横越车道时间进行优化，采用MATLAB软件开展仿真测试,并进行实车验证。结果表明：优化后的LDW决策处理系统可以根据当前车辆状态提前进行车辆偏离预警，而且不频繁报警，具有较好的实用性。

Abstract：To improve the effectiveness and reasonableness of the lane departure warning (LDW) system for commercial vehicles, according to the mass, structure, control and other characteristics of commercial vehicles, the LDW decision-making processing system for commercial vehicles is designed by vehicle mass and longitudinal speed. The time for crossing lanes of vehicles is optimized based on fuzzy control theory, and MATLAB simulation and vehicle validation are performed. The results show that the optimized LDW decision processing system can provide early warning of vehicle departures according to current vehicle conditions, and it will not warnings frequently to affect driving, which shows a relatively good utility.
