DEVICE FOR CONTROLLING ELECTRIC VEHICLE

摘要

PROBLEM TO BE SOLVED: To consume all electric power supplied from a power supply source as driving power by a driving motor while controlling torsional vibration of a driving system in an electric vehicle driven by the driving motor.SOLUTION: A device for controlling an electric vehicle which includes the driving motor 15 that generates driving torque to be transmitted to a driving wheel 18a and power supply sources 12 and 17 that include at least a generator 12 to supply power to the driving motor 15, comprises a required driving torque calculating means 20 that calculates required driving torque based on the traveling state of a vehicle; a supply power calculating means 20 that calculates supply power to be supplied to the driving motor 15 by the power supply sources 12 and 17 based on the required driving torque; a driving torque directing means 20 that controls the driving motor 15 such that the driving torque obtained by reducing a frequency component equivalent to the torsional vibration of the driving system from the necessary driving torque is output; and a supply power directing means 20 that controls the power supply sources 12 and 17 such that power obtained by reducing the frequency component equivalent to the torsional vibration of the driving system from the supply power is supplied to the driving motor 15.
