<P>PROBLEM TO BE SOLVED: To suppress excessive voltage drop of a capacitor 57 and suppress the output of torque to a driving shaft 32 when a shift lever 81 is operated from a drive position to a neutral position during travelling in a battery shut-off state where a battery 50 is disconnected from a power bus bar 54 of inverters 41, 42, 90. <P>SOLUTION: When the shift lever is operated to the neutral position during travelling in the battery shut-off state, a capacitor voltage Vc becomes close to a target voltage Vc*, and also an engine 22 and two motors MG1, MG2 are controlled so that torque is not output to a ring gear shaft 32a as the driving shaft. Thereby, in comparison with the case in which the inverters 41, 42 are shut down, excessive voltage drop of the capacitor 57 caused by power consumption of an air conditioner compressor 92 may be suppressed and also the output of the torque to the driving shaft 32 may be suppressed. <P>COPYRIGHT: (C)2008,JPO&INPIT |
