A driving assistance system is provided with a roadside server connected to a roadside sensor and a roadside device. The roadside server has a sensor information processing unit, an auxiliary information generation unit, and a roadside machine interface. The sensor information processing unit uses information indicating the state of the detection range of the roadside sensor from the roadside sensor to generate sensing information of a first dynamic object within the detection range. The assistance information generation unit generates driving assistance information including the position and speed of a dynamic object within the information provision range by merging the sensing information and peripheral object information obtained by extracting predicted position information present within the information provision range. The predicted position information is the predicted position information of the second dynamic object predicted based on detection information including the position and speed of the second dynamic object within a predetermined range, and taking into account wide-area communication by wireless communication via the base station and the delay of processing in the roadside server; the information providing range is a range that includes the detection range and is larger than the detection range. And the roadside machine interface sends the driving assistance information to the roadside machine.
驾驶辅助系统具备与路侧传感器及路侧机连接的路侧服务器。路侧服务器具有传感器信息处理部、辅助信息生成部以及路侧机接口。传感器信息处理部使用来自路侧传感器的表示路侧传感器的检测范围的状态的信息,生成检测范围内的第1动态物体的感测信息。辅助信息生成部将周边物体信息与感测信息合并而生成包含信息提供范围内的动态物体的位置和速度的驾驶辅助信息,其中,该周边物体信息是提取了存在于信息提供范围内的预测位置信息而得到的,该预测位置信息是根据探测信息、并考虑经由基站的利用无线通信的广域通信和路侧服务器中的处理的延迟而预测的第2动态物体的预测位置信息,该探测信息包含预先决定的范围内的第2动态物体的位置和速度,该信息提供范围是包含检测范围且比检测范围大的范围。路侧机接口向路侧机发送驾驶辅助信息。
