To provide a vehicular comprehensive control system that enables appropriate engaging pressure control, line pressure control or parameter learning irrespective of an operating cycle of an engine.

An estimate input torque varying means 182 varies an estimate value TIN of input torque to an automatic transmission 16 according to a variation in the operating cycle of the engine 10 to thereby provide an accurate estimation of input torque corresponding to an actual operating cycle, so that engaging pressure control, line pressure control and the like executed according to the estimate input torque TIN are appropriate to suppress a shift shock and the like appreciably.
