The system includes a vehicle (300) and a remote centre (100), which manages traveling information of a plurality of vehicles. The remote centre (100) transmits a message containing a collection condition to the in-vehicle communication set (310) by wireless communication. The message has a header and a plurality of frames. The header identifies the in-vehicle communication set (310) as the destination. Each frame has three fields (F1A, F1B, F1C). The Destination ECU is not used in the message from the remote centre (100) to the communication set (310). A destination information conversion unit (313) in the in-vehicle communication set (310) fills in this field before sending the frame over the vehicle network (NW). An information collection control device (320, 310A) collects vehicle data from control devices (330,331) connected to the vehicle network (NW) according to the collection condition and returns collected vehicle data to the remote centre (100). |
