<P>PROBLEM TO BE SOLVED: To provide a vehicle drive controller which performs stable motor torque control by a combination of a dynamo and an AC motor. <P>SOLUTION: A target output power PG to be outputted by the dynamo 7 is calculated on the basis of a motor needed power Pm needed by a motor 4, and the dynamo 7 is controlled at a target operation point wherein a torque instruction value Tt calculated on the basis of the target output power PG is efficiently generated. In this case, an upper limit of a target voltage Vt of the target operation point is set according to an engine speed Ng. A torque instruction value Tm for the motor 4 is calculated on the basis of a present output voltage V and an output current I of the dynamo 7, and the motor 4 is controlled on the basis of the torque instruction value Tm. <P>COPYRIGHT: (C)2007,JPO&INPIT |
