<P>PROBLEM TO BE SOLVED: To optimize the control of driving force distribution between multiple power sources in a power output unit in which some of the power sources generate driving force by electric power from a secondary battery. <P>SOLUTION: A driving force distribution determination unit 170 sets the upper limit value of motor output power on the basis of the average overall SOC in entire secondary batteries, computed by an overall SOC computation unit 150, and then primarily sets driving force distribution between motor output power Pe and engine output power Pe. A driving force distribution correction unit 180 operates as follows: when the local SOC based on the estimated ion concentration distribution in the secondary batteries computed by a local SOC computation unit 160 is lower than the overall SOC, it computes the upper limit value of motor output power corresponding to the local SOC; when the motor output power Pe determined by the driving force distribution determination unit 170 is higher than the computed upper limit value of motor output power, it takes the upper limit value of motor output power as the final motor output power Pe#. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
