| 摘 要： | 针对“距离-损耗”模型在车载自组网无线定位中的局限性,根据此模型提出了一种基于三角形形心的近似定位算法模型,设计了合理的校准方法对给出的模型进行校准.建立车载自组网软硬件实验环境,从距离误差和定位精度两方面对标定的模型进行了实验验证.结果表明,超过95%实验数据的定位精度小于3 m,研究得到的无线定位算法能满足低速情况下车辆主动安全的需要.

| Abstract: | Due to the limitation of distance-loss model in wireless positioning of vehicular ad hoc networks,the paper presents an approximate positioning algorithm model based on triangle centroid according to this model.The model is marked by reasonable calibration method and the hardware and software experimental environment of vehicular ad hoc networks is established.The distance errors and position accuracy of the model is verified.The results show that over 95% of positioning accuracy experimental data is less t... |
