INSIDE/OUTSIDE VEHICLE DETERMINATION SYSTEM FOR WIRELESS COMMUNICATION DEVICE, INSIDE/OUTSIDE VEHICLE DETERMINATION DEVICE FOR WIRELESS COMMUNICATION DEVICE, AND INSIDE/OUTSIDE VEHICLE DETERMINATION CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To accurately determine whether a wireless communication device is in a vehicle or not by using hardware resources held by the wireless communication device.SOLUTION: Regarding a wireless communication device 102-1, as shown in Figure 1 (1-1), an inside/outside vehicle determination device 101 notifies a wireless communication device 102 of an inside/outside vehicle determination request by short-range wireless communication. Then, the inside/outside vehicle determination device 101 applies current to a coil 111 upon reception of a response to the inside/outside vehicle determination request as shown in Figure 1 (2). The wireless communication device 102-1 measures strength of a generated magnetic field with a magnetic sensor 112-1, and transmits a measurement result to the inside/outside vehicle determination device 101 by short-range wireless communication as shown in Figure 1 (3-1).SELECTED DRAWING: Figure 1
