Traction motor control apparatus for vehicle

摘要

The traction motor control apparatus has a correction means for correcting an error included in a rotation detection signal outputted from a rotation angle sensor and outputting it as corrected rotation data for control of a motor. The correction means includes a rotation time predicting section configured to predict a predicted time necessary for the motor to rotate by a predetermined reference angle on the basis of a time having been elapsed for the motor to rotate by a predetermined angle, the time being calculated from the rotation detection signal outputted from the rotation angle sensor, a predicted rotation data generating section configured to generate a predicted rotation angle of the motor on the basis of the predicted time, and a corrected data updating section configured to update the corrected rotation data presently being outputted from the correction means in accordance with the predicted rotation angle.
