<P>PROBLEM TO BE SOLVED: To control a terminal voltage of a secondary battery of a hybrid vehicle so as not to drop below a lower limit of a usable range. <P>SOLUTION: A current integration value S is computed, which increases more when the discharge of the secondary battery continues for a longer time, and decreases more when time passes more after stopping discharging. A start determination voltage Vref which performs start determination of an internal combustion engine is corrected based on the current integration value S. The start determination voltage Vref is made to increase more, if the current integration value S is larger. <P>COPYRIGHT: (C)2012,JPO&INPIT |
