Document Type and Number:
Japanese Patent JP5837200
Kind Code:
B2
Abstract:
A control unit (70) acquires the movement history (113) of another device from the other device via a communication unit (50), acquires the present position (11) and movement direction (12) of its own device (10) from a detection unit (60), and determines whether or not the movement history (113) of the other device enters a movement history determination range that is a predetermined range set in the movement direction (12) of the device (10) with the present position (11) of the device (10) as a starting point. If it is determined that the movement history (113) of the other device enters the movement history determination range, the control unit (70) makes a probe information transmission request (71) that requests the transmission of probe information (114) held by the other device via the communication unit (50). If it is determined that the movement history (113) of the other device does not enter the movement history determination range, the control unit (70) does not make the probe information transmission request (71).
