Title:
ESTIMATION APPARATUS AND ESTIMATION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/123670
Kind Code:
A1
Abstract:
Provided are an estimation apparatus and an estimation method for estimating the clutch abrasion amount. This estimation apparatus is provided with: sensors (50, 51) that acquire a clutch slipping amount; an acceleration sensor (54) that acquires the acceleration of a vehicle (1); a vehicle weight sensor (55) that acquires the weight of the vehicle (1); temperature acquisition units (57, 120) that acquire a clutch temperature; an absorbed energy calculation unit (110) that calculates the absorbed energy of a clutch on the basis of a clutch slipping amount, acceleration, and vehicle weight when the vehicle starts moving; a cumulative damage level calculation unit (130) that calculates the cumulative damage level by integrating the damage level obtained by multiplying the absorbed energy by the clutch temperature; and an abrasion amount estimation unit (140) that estimates a clutch abrasion amount on the basis of the cumulative damage level.
