Abstract
An object of the invention is to provide an acceleration control apparatus, according to which accuracy for feed-forward torque may not be decreased even when a calculating accuracy for an estimated-slope torque would be decreased. Reliability of estimated slope is calculated and feedback torque is corrected, in such a manner that a gain for a feedback control portion is increased when the reliability of the estimated slope becomes lower. It is, therefore, possible to compensate a possible decrease of the accuracy of the feed-forward torque by correcting the feedback torque in accordance with the reliability of the estimated slope.
