<p><P>PROBLEM TO BE SOLVED: To provide an on-vehicle apparatus control system capable of providing data for estimating an abnormal place and an abnormal cause and determining the replacement of a part in an inspection and repairing. <P>SOLUTION: Respective actuator units MIX, MODE and F/R supply these abnormal information to the main control part 100 side when detecting operational abnormality such as a communication error such as a parity error and a thumb check error, overvoltage, an overcurrent and the excessive temperature. An abnormality occurrence frequency control means 121 integrates and stores an abnormality occurrence frequency in accordance with an actuator unit and a kind of abnormality. A communication frequency control means 122 integrates and stores a data communication frequency in accordance with the actuator unit. An abnormality occurrence rate calculating means 123 calculates an abnormality occurrence rate from the data communication frequency and the abnormality occurrence frequency. An output processing means 124 outputs the abnormality occurrence frequency, the data communication frequency and the abnormality occurrence rate to a diagnostic analytical device for repairing/inspection. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
