VEHICLE DATA ACQUISITION SYSTEM AND VEHICLE DATA ACQUISITION METHOD

摘要

Provided is a vehicle data acquisition system that stores, in a memory device (31), vehicle data acquired by way of a vehicle-mounted information processor (21). A data acquisition program (12) assisting the acquisition of the vehicle data is dynamically incorporated in the vehicle-mounted information processor (21). A probe section (P), which can be replaced with another command, is positioned as an invalid command in one or a plurality of positions in an application program (11) incorporated in advance in the information processor (21). The data acquisition program (12) replaces the probe section (P) with a vehicle data acquisition command and stores the acquired vehicle data in chronological order in the memory device (31). The data acquisition program (12) re-replaces the probe section (P) with an invalid command after the vehicle data is acquired.
