<P>PROBLEM TO BE SOLVED: To suppress the local heating of a power device such as a motor or inverter for traveling, and to improve escaping capability from a stall status. <P>SOLUTION: In a hybrid vehicle 1 where a transmission 14 is connected through a first clutch 13 to an internal combustion engine 11 and a first motor 12 serially connected to front wheels Wf and Wf, a second motor 16 configuring a three-phase brushless DC motor is connected through a second clutch 15 to the transmission 14. When a vehicle is started by the driving force of the second motor 16 from the idle status of the internal combustion engine 11, a motor output control part 18 calculates a torque requested to the second motor 16 according to the tilt angle of the traveling surface of a vehicle, and calculates a continuous power supply time T1 corresponding to the stator coil of any phase of the second motor 16. After power supply, whether or not the rotational frequency of the second motor 16 is predetermined rotational frequency or less is decided, and when the decision result is "YES", the fastening force of the second clutch 15 is temporarily relaxed. <P>COPYRIGHT: (C)2007,JPO&INPIT |
