Abstract
For clutch (23) in vehicle driving force transmitting system, having operating states of full engagement, slip engagement and disengagement, there are provided heat generation calculating section (32) calculating per-unit-time temperature increase ΔT(up) from heat generation quantity (Σt) generated among friction material members of clutch (23), heat dissipation calculating section (33) calculating per-unit-time temperature decrease ΔT(down) from heat dissipation quantity f(t) dissipated from the friction material of clutch (23), and clutch temperature estimation calculating process section (31) calculating current clutch temperature Tnow by adding temperature variation ΔT to previous clutch temperature Tpv. Heat dissipation calculating section (33) estimates a quantity of lubricating oil passing around the friction material of clutch (23) and uses the estimated lubricating oil quantity for the heat dissipation quantity f(t) dissipated by heat transfer from the friction material to the lubricating oil.
