Problems solved by technology

[0008] However, the technology in Patent Document 1 has a disadvantage in that in order to always record the above-mentioned various state information in the vehicle-mounted system, the data capacity of the storage medium becomes very large
In contrast, the disadvantage of the technology in Patent Document 2 is that by sending the above-mentioned various status information to an external vehicle service center for storage, the cost of data communication becomes very large

Abstract

In cases that one of conditions registered in a record data classification table is satisfied, the accordance with a condition for recording in a nonvolatile record data database is determined. A cycle record data element according with a record content corresponding to the condition determined to be satisfied is retrieved from cycle record data elements recorded in a cycle record data database. Retrieved cycle record data element is recorded in the nonvolatile record data database as nonvolatile record data. Those conditions are satisfied, respectively, as follows: (i) in cases that a vehicular system starts; (ii) in cases that a system parameter is changed; (iii) in cases that a specified time elapses after departure; (iv) in cases that it comes to the time before arrival; (v) in cases that a subject vehicle is located in a user defect detection area; and (vi) in cases that an external remote manipulation is executed.

Description

technical field [0001] The present invention relates to a technique for recording vehicle state information that contributes to cause determination of a defect having a low occurrence frequency or a low detection frequency while having difficulties in reproduction and cause identification, which also identifies the cause of the defect based on the recorded information . Background technique [0002] [Patent Document 1] JP-2009-145117A (WO 2009-075338) [0003] [Patent Document 2] JP-2005-146905A [0004] A method is generally known for monitoring vehicle information on the state of a vehicle, thereby detecting a defect of the vehicle based on the monitored vehicle information, and recording the monitored vehicle information at the time of detection of the defect in a nonvolatile permanent storage media, etc. Furthermore, the information thus stored in the nonvolatile storage medium can be used to verify the cause of the defect. This verification of the cause of the defec...
