<P>PROBLEM TO BE SOLVED: To provide a vehicular driving controller which performs stable motor torque control by a combination of a power generator and an AC motor. <P>SOLUTION: A target output power PG to be outputted by the power generator 7 is calculated on the basis of a motor needed power Pm needed by the motor 4, and the power generator 7 is controlled at an operation point wherein a torque instruction value Tt calculated on the basis of the target output power PG is efficiently generated. A torque instruction value Tm is calculated on the basis of the operation point present inside the stable operation range (wherein a power generator output voltage does not exceed a fail voltage V<SB>max</SB>) on an outputtable characteristic line St determined from a present output current I and output voltage V of the power generator 7, and the motor 4 is controlled on the basis of the torque instruction value Tm. <P>COPYRIGHT: (C)2007,JPO&INPIT |
