DETERIORATION DETECTION DEVICE FOR VEHICLE COMPONENT DEVICE

Title:

DETERIORATION DETECTION DEVICE FOR VEHICLE COMPONENT DEVICE

Document Type and Number:

WIPO Patent Application WO/2011/114419

Kind Code:

A1

Abstract:

Provided is a deterioration detection device for a vehicle component device capable of detecting deterioration for the vehicle component device on the basis of more precise analysis. A control unit (50) performs a process for estimating a deterioration state on a per-portion basis. This process subdivides a component into portion levels (part and position) and estimates the degree of deterioration. Specifically, with respect to a throttle gear (20) and gears (10,12,14), the amount of deterioration for each gear tooth in each gear is calculated according to the deterioration function of each gear.
