Title:
DURABILITY LIFE MANAGEMENT DEVICE OF POWER TRANSMISSION SYSTEM AND DURABILITY LIFE MANAGEMENT METHOD OF POWER TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/150941
Kind Code:
A1
Abstract:
In order to estimate the degree of fatigue in a power transmission system and suitably manage a durability life, this durability life management device of the power transmission system is provided with: an input unit which receives an input of vehicle travel information including a torque generated by a driving source; a control unit which controls the degree of damage to a component of the power transmission system on the basis of the travel information and determines, on the basis of the degree of damage, whether the degree of fatigue in the power transmission system is high; and an output unit which outputs a signal indicating that the degree of fatigue is high, when the degree of fatigue is determined to be high.
