<P>PROBLEM TO BE SOLVED: To secure the following performance of an engine rotation number with respect to an abrupt change of required torque while further suppressing the hunting of the engine rotation number. <P>SOLUTION: When an engine first temporary target rotation number Ne1* and an engine second temporary target rotation number Ne2* are target rotation numbers in such a way that change directions of an engine target rotation number Ne* become the same (YES in S380 or S390), a value obtained by adding the previous Ne* and a value larger in absolute value out of target rotation number change amounts ΔNe1*, ΔNe2* which are adjusted so as not to exceed a first upper limit value Ne1ref (S320 to S370) is set as the engine target rotation number Ne* (S400, S410). In the case other than this (NO in S390), a value obtained by adding the previous Ne* and the target rotation number chamber amount ΔNe2* which is adjusted so as not exceed a second upper limit value Ne2ref (<first upper limit value Ne1ref) (S350 to S370) is set as the engine target rotation number Ne* (S400, S410). <P>COPYRIGHT: (C)2013,JPO&INPIT |
