VEHICLE POSITION ESTIMATION SYSTEM
A vehicle position estimation system, wherein a plurality of onboard communications devices (12) each arranged at different positions in the vehicle determine the position of a mobile terminal relative to the vehicle, by wireless communication with the mobile terminal. Each of the plurality of onboard communications devices can wirelessly communicate with at least two of a plurality of other devices and comprises: a distance index value acquisition unit (S203) that, by causing each set of onboard communications devices that are in a positional relationship whereby wireless communication is possible to perform wireless communications, obtains a distance index value indicating the distance between the onboard communications devices; a normal range storage unit (M1) that stores data indicating a normal range for the distance index value; and a communications device diagnostic unit (F6) that determines whether or not the onboard communications devices are normal. The communications device diagnostic unit determines that no malfunction has occurred in the device being diagnosed, if the distance index value between the device being diagnosed and at least one other device is within the normal range.
本发明提供车辆用位置推断系统，在车辆中分别配置于不同的位置的多个车载通信器(12)通过与移动终端无线通信来判定移动终端相对于车辆的位置。多个车载通信器中的每个车载通信器能够与多个其它设备中的至少2个其它设备实施无线通信，具备：距离指标值获取部(S203)，通过按照处于能够相互无线通信的位置关系的车载通信器的每个组合实施无线通信，来获取表示车载通信器间的距离的距离指标值；正常范围存储部(M1)，存储有表示距离指标值的正常范围的数据；以及通信器诊断部(F6)，判定车载通信器是否正常。在诊断对象设备与至少一个其它设备之间的距离指标值为正常范围内的值的情况下，通信器诊断部判定为诊断对象设备未产生不良情况。
