Abstract
A propulsion motor control apparatus for a battery vehicle including; a steering angle detection device for detecting a steering angle subtended between a common axis of two front wheels, and an axis of a rear wheel. Also included is a ratio computing device for computing a ratio between a distance between an intersection point of the two axes and a front wheel (outer wheel) on a side further from the intersection point, and a distance between the intersection point and a front wheel (inner wheel) on a side closer to the intersection point, based on the steering angle, a function determining device for determining a motor rotation speed/current command value function for the inner wheel based on a motor rotation speed/current command value function for the outer wheel and the obtained ratio, and a control device for individually controlling the respective propulsion motors for the two front wheels based on the two functions.
