IN-VEHICLE ELECTRONIC APPARATUS AND DIAGNOSTIC SYSTEM
First Claim
1. An in-vehicle electronic apparatus in a vehicle to store analysis information to analyze causes of predetermined vehicle behaviors,the in-vehicle electronic apparatus comprising:
- a change determination section that determines whether a plurality of driving informational parameters representing driving states of the vehicle indicate predetermined changes, respectively;
a behavior determination section that determines whether a predetermined vehicle behavior occurs; and
a storage section that stores, in a storage portion as analysis information, (i) an occurrence time of the predetermined vehicle behavior, which is determined to occur by the behavior determination section, as well as (ii) a change time of the driving informational parameter determined to indicate the predetermined change by the change determination section by the occurrence time of the predetermined vehicle behavior.

Abstract
When any one of multiple driving informational parameters has shown a predetermined change in a determination process, an in-vehicle electronic apparatus sets 1 to a change history provided per each driving informational parameter. When the change history of any one of the driving informational parameters is 1 in the storage process, the in-vehicle electronic apparatus determines that any one of the driving informational parameters has shown the predetermined change between the previous process and current process. Then, the in-vehicle electronic apparatus stores a current time as a change time in a corresponding area provided in an RAM to the driving informational parameter that has shown the predetermined change and sets the change history to 0. When the predetermined vehicle behavior occurs, the in-vehicle electronic apparatus stores, in an SRAM or EEPROM, the change time stored in the RAM and an occurrence time when the predetermined vehicle behavior occurs.
