<P>PROBLEM TO BE SOLVED: To provide a driving force control device of a motor-driven vehicle which repeatedly outputs short-time maximum torque Tmax by cooling an inverter circuit while preventing the vehicle from sliding down on a slope when the a motor is locked at the start on the slope. <P>SOLUTION: The driving force control device 10 of the motor-driven vehicle comprises: an electric motor 11; the inverter circuit 13; a brake control device 15; and a torque control device 12. The torque control device 12 comprises: a vehicle fixing module 19 which causes the brake control device 15 to operate a brake 14 when a temperature of the inverter circuit 13 in the motor-locked state is not lower than a prescribed temperature; a torque generation limiting module 20 which recognizes the operation of the brake 14, and prohibits the generation of the torque of the electric motor 11; and a torque increase module 21 which generates the short-time maximum torque Tmax when the temperature of the inverter circuit 13 becomes lower than the prescribed temperature due to the prohibition of generating the torque. <P>COPYRIGHT: (C)2010,JPO&INPIT |
