PROBLEM TO BE SOLVED: To prevent overvoltage from being produced in an inverter for giving and receiving electric power to and from a driving motor (rotary electric machine) coupled with wheels in a hill start (climbing a hill). SOLUTION: A vehicle 1 has a rotary electric machine MG2 as a power plant. Further, it has a second resolver 34 as a means capable of detecting the rotating state of wheels, provided in the rotary electric machine MG2, and HV-ECU 60 that determines a torque command value for the rotary electric machine MG2 based on driving operation information. When it is determined that the direction of wheel rotation and the direction of the torque of the rotary electric machine MG2 are opposite to each other based on the state of wheel rotation detected by the second resolver 34 and a torque command value for the rotary electric machine MG2, the HV-ECU 60 zeroes the torque command value for the rotary electric machine MG2. Based on this torque command value, the rotary electric machine MG2 is controlled by MG-ECU 80. COPYRIGHT: (C)2007,JPO&INPIT
