<P>PROBLEM TO BE SOLVED: To provide a motor control device of electric vehicle advantageous in controlling heat generation of a motor more effectively, while securing demanded torque. <P>SOLUTION: A first drive control means 50A, when driving torques outputted from a front motor 18 and a rear motor 20 are respectively considered as first and second drive torques, carries out driving control of each motor by distributing the demanded torque demanded by running operation of a driver to first and second driving torques so that efficiency of the motors 18 and 20 as a whole may be maximum. A determination means 50B determines whether the time when either one of the first or second driving torque has exceeded the reference torque is the predetermined time or longer. A second drive control means 50C, when determined that the time is the predetermined time or longer, satisfies the demanded torque by increasing the driving torque of the motor of another side, while decreasing the driving torque of the motor determined that is more than predetermined time T0 rather than reference torque. <P>COPYRIGHT: (C)2012,JPO&INPIT |
