The invention belongs to the technical field of intelligent traffic systems, and particularly discloses a vehicle-mounted network channel congestion control method and system based on a regional risk factor, and the system evaluates the driving risk of a single vehicle by using a combined fuzzy reasoning method based on a driver factor, a vehicle factor and an environment factor which influence the driving safety; the driving risk of the road area is evaluated, and the driving risk short-term prediction is carried out on the road area by using a convolutional long-short-term memory neural network; constructing a non-cooperative game model, and incorporating the driving risk and the safety message of the road area where the vehicle is located into a utility function of the non-cooperative game model; and solving the utility function to obtain an equalization strategy for channel congestion control of the vehicle-mounted network. By adopting the technical scheme, the influence of the interaction of the driver factor, the vehicle factor and the environment factor on the driving risk can be comprehensively and effectively evaluated, and a more comprehensive and more accurate driving risk evaluation result can be obtained.

    本发明属于智能交通系统技术领域,具体公开了一种基于区域危险度的车载网信道拥塞控制方法及系统,该系统基于影响行车安全的驾驶员因素、车辆因素和环境因素,运用组合模糊推理方法对单车辆的行车风险进行评估;评估道路区域的行车风险,并使用卷积长短期记忆神经网络,对道路区域进行行车风险短时预测;构建非合作博弈模型,将车辆所在道路区域的行车风险和安全消息纳入非合作博弈模型的效用函数内;求解效用函数,得到车载网信道拥塞控制的均衡策略。采用本技术方案,能够全面、有效地评估驾驶员因素、车辆因素和环境因素相互作用对行车风险的影响,得到更全面、更准确的行车风险评估结果。
