<P>PROBLEM TO BE SOLVED: To provide a four-wheel drive control device capable of performing control such that generation power of a power generator becomes a desired target value. <P>SOLUTION: The four-wheel drive control device 1 includes: a map retrieval unit 41 for calculating power necessary for a motor 15 from target torque needed for sub drive wheels 18, and for calculating a target power W<SP>*</SP>to be output by the power generator 13 based on a calculation result; a DC power calculation unit 43 for calculating an actual output power W actually output by the power generator 13; and a PI control unit 43 for reducing an instruction value Id<SP>*</SP>of a d shaft current that is a loss current when the target current W<SP>*</SP>calculated by the map retrieval unit 41 is smaller than the actual output power W calculated by the DC power calculation unit 42, and for increasing the instruction value Id<SP>*</SP>of the d shaft current that is the loss current when the target power W<SP>*</SP>calculated by the map retrieval unit 41 is larger than the actual output power W calculated by the DC power calculation unit 42. <P>COPYRIGHT: (C)2010,JPO&INPIT |
