<p><P>PROBLEM TO BE SOLVED: To provide an electric vehicle wherein speed can be controlled with high response and following capability by directly determining an optimum torque command signal to be inputted to an in-wheel motor 9 from the running load of the electric vehicle as well as the difference between a target running speed and a detected running speed. <P>SOLUTION: An acceleration is determined from change in detected running speed by an acceleration acquisition means 15. The running load of the electric vehicle is determined from this acceleration and the output torque of the in-wheel motor 9 by a running load acquisition means 16. In correspondence with this running load, a torque command signal to be inputted to the in-wheel motor 9 is determined by a torque command signal control means 14 so as to produce an output torque for obtaining an acceleration with which the difference between the target running speed and the detected running speed is eliminated. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
