In step S140, by any time to the cumulative damage degree Σ D that last time is generatedN-1In addition the damage calculated by step S130
Evil degree Dn, thus in real time to cumulative damage degree Σ DnCarry out operation.
In step S150, by based on the cumulative damage degree Σ D to be generated by step S140nIt is pushed away referring to abrasion loss
Table (referring to Fig. 4) is determined, to estimate clutch abrasion amount Wc.
In step S160, determine whether clutch abrasion amount Wc has reached upper limit threshold.It is reached in clutch abrasion amount Wc
In the case where having arrived upper limit threshold (affirmative), this control proceeds to step S180, and implementation will need replacing clutch friction plate 23
Meaning display warning on display 80.
On the other hand, in the case where clutch abrasion amount Wc is not up to upper limit threshold (negative), this control proceeds to step
Rapid S170 determines whether clutch slip amount Δ Nc is 0 (zero).In the case where clutch slip amount Δ Nc is not 0 (negative),
This control returns to step S110, and executes and manage everywhere in above-mentioned step S110~S160 repeatedly, until clutch slip amount Δ
Until Nc becomes 0.On the other hand, in the case where clutch slip amount Δ Nc is 0 (affirmative), this control is returned, and is protected
Until being left to next vehicle start.
As described in detail above, estimating device according to the present embodiment, clutch friction when based on vehicle start
The absorption energy Q of the piece 23 and cumulative damage degree D calculated according to clutch temp Tc estimates clutch abrasion amount Wc,
And reach close to completely worn out scheduled upper limit threshold in clutch abrasion amount Wc (for example, 90 when relative to new product
~95% abrasion loss) in the case where, implementation makes driver learn the warning for needing replacing the meaning of clutch friction plate 23.By
This, can effectively estimate clutch abrasion amount Wc on one side, on one side the appropriate suitable opportunity for holding replacement component, so as to
It prevents from being equal to possible trouble by the completely worn out caused road failure of clutch friction plate 23.
In addition, the disclosure is not limited to above-mentioned embodiment, it can be in the range for not departing from purport of the invention
It is interior it is appropriate deformation and implement.
For example, be although the description of clutch temp Tc estimated based on the lubricating oil temperature To of speed changer 40, but
It can be, in the case where including the temperature sensor (not shown) of the temperature of detection bell housing 21, be based on the temperature sensing
The sensor values of device estimates.
In addition, vehicle 1 is not limited in the vehicle including engine 10 as driving source, or including travelling with electronic
The hybrid vehicle etc. of machine.
The application, and will be in it based on Japanese patent application (Patent 2016-252379) filed on December 27th, 2016
