根據目前中國路橋車輛收費標準，提出了一種基于模糊模式識別的車型分類系統。車輛經過環形線圈傳感器時，形成感應曲線，提取感應曲線的特征并進行特征分離，利用模糊模式識別方法對車型進行匹配分類。研究結果已在路橋收費系統以及交通流量統計中得到應用。
關鍵詞：模糊模式識別；車輛分類；特征分離
【Abstract】According to the toll standard on freeway and bridge in China,a vehicle classification system based on fuzzy pattern recognition is put forward. To introduce a method for vehicle classification based on the loop sensors,when the vehicle is passing, it can form a response curve caused by the vehicle pass. The fuzzy pattern recognition with character separation was used to classify vehicles according to the curve from the loop sensor. The research result was applied in the freeway and bridge toll system and the traffic-flow statistics system.
【Key words】F uzzy pattern recognition ; Vehicle classification ；Character separation
