PROBLEM TO BE SOLVED: To control the switching-drive of a power converter appropriately in accordance with the presence of occurrence of an excessive voltage abnormality and that of occurrence of a vehicular collision.SOLUTION: In a case where an excessive voltage abnormality in a power system 10 is detected, with no collision of a vehicle detected, a switching control part 56 stops the switching-drive of inverters 16, 17 to thereby suppress an event where an excessive voltage is applied to elements of the inverters 16, 17. In contrast, in a case where a collision of the vehicle is detected even with an excessive voltage abnormality in the power system 10 detected, the switching control part 56 performs the switching-drive of the inverters 16, 17, consuming electric energy of the power system 10 quickly using motor generators 18, 19. |
