Abstract
A useful life estimating apparatus for a vehicle component that prevents the component from reaching the end of useful life before the end of an expected useful life thereof. The controller includes: a history memory for storing a load on the predetermined component; a comparer for comparing an actual fatigue of the component stored in the history memory with a reference fatigue; and a determiner for determining that the component will reach the end of the useful life before the end of a reference useful life, when the comparer determines that the actual fatigue is greater than the reference fatigue.
Claims6
A useful life estimating apparatus that estimates a useful life of a predetermined component arranged in a vehicle, comprising:
- a controller that determines the useful life of the predetermined component,
- wherein the controller comprises
- a history memory that is configured to store a load acting on the predetermined component,
- a comparer that is configured to compare an actual fatigue of the predetermined component calculated based on the load stored in the history memory with a reference fatigue calculated based on a predetermined load expected to act on the predetermined component, and
- a determiner that is configured to determine that the predetermined component will reach an end of the useful life before an end of a reference useful life, when the comparer determines that the actual fatigue is greater than the reference fatigue.
