Evaluation, system for fault diagnosis function, computer program product, and computer readable storage medium
First Claim
1. An evaluation system for a fault diagnosis function that diagnoses a certain equipment, comprising:
- a completion status determination part that determines whether a diagnosis process of the diagnosis function is completed or not; and
a diagnosis function evaluation part that determines that the fault diagnosis function is not in a normal condition when the diagnosis process is not completed during one of a predetermined number and a predetermined time period.

Abstract
An evaluation system for a fault diagnosis function has an engine ECU. The ECU is connected to an engine, sensors, and a MIL. The ECU diagnoses the sensors. The ECU also determines whether a diagnosis process of the diagnosis function for the sensors is completed. A memory stores a plurality of the completion result. When at least one of the diagnosis processes is completed in the last ten completion result, it is determined that the diagnosis function is in a normal condition. Otherwise, it is determined that the diagnosis function is in an abnormal condition, and the MIL indicates the abnormal condition.

5. An evaluation system for a fault diagnosis function that diagnoses a certain equipment, comprising:
-
a completion status determination part that determines whether a diagnosis process of the diagnosis function is completed or not;
a ratio calculation part that calculates at least one of a completion ratio in which the diagnosis process is completed and an incompletion ratio in which the diagnosis process is not completed based on a determination result of the completion status determination part within one of a predetermined number and a predetermined time period; and
a diagnosis function evaluation part that evaluates the fault diagnosis function based on one of the completion ratio and the incompletion ratio. - View Dependent Claims (6, 7, 8)

9. An evaluation system for a fault diagnosis function that diagnoses a certain equipment, comprising:
-
a completion status determination part that determines a completion status relating to a diagnosis process of the diagnosis function;
a status memory that stores the completion status;
a deletion part that deletes the completion status stored in the status memory in response to a request signal from an external device;
a ratio calculation part that calculates at least one of a completion ratio in which the diagnosis process is completed and an incompletion ratio in which the diagnosis process is not completed based on determination results of the completion status determination part after deleting the completion status stored in the status memory by the deletion part; and
a diagnosis function evaluation part that evaluates the fault diagnosis function based on one of the completion ratio and the incompletion ratio. - View Dependent Claims (10, 11, 12)
