Abstract: A wireless communication device mountable in a vehicle acquires first position information on the vehicle and receives a packet signal from another wireless communication device, the packet signal including second position information on another vehicle in which the other wireless communication device is mounted. The wireless communication device has a storage that stores log information and a controller. The controller predicts whether the vehicle crosses the other vehicle at a point of crossing based on the first position information and the second position information, estimates a structure of crossing corresponding to the point of crossing based on the history information, and determines, when it is predicted that the vehicle crosses the other vehicle at the point of crossing, whether or not to notify a presence of the other vehicle to a driver of the vehicle, in accordance with the structure of crossing corresponding to the point of crossing.

Abstract: A modulating and demodulating section receives, from another radio device, a packet signal including at least position information of another vehicle in which the other radio device is mounted. A position information acquiring section acquires position information of the vehicle in which the radio device is mounted. An estimating section estimates a time taken for the vehicle and the other vehicle to encounter each other on the basis of these two pieces of position information. A deriving section derives a distance between the vehicle and the other vehicle on the basis of these two pieces of position information. A determining section provides notification of an encounter with the other vehicle in a case where the estimated time is equal to or less than a first threshold value or in a case where the derived distance is equal to or less than a second threshold value.

Abstract translation: 调制解调部分从另一个无线电设备接收至少包括安装另一无线电设备的另一车辆的位置信息的分组信号。 位置信息获取部分获取安装无线电设备的车辆的位置信息。 估计部分基于这两个位置信息来估计车辆和另一车辆相互遇到的时间。 导出部分基于这两个位置信息导出车辆与另一车辆之间的距离。 在所述估计时间等于或小于第一阈值的情况下，或在所述导出距离等于或小于第二阈值的情况下，确定部分提供与所述另一车辆相遇的通知。
