Abstract:
1. In an acceleration control apparatus for a vehicle comprising; a feed-forward control portion for carrying out a feed-forward control based on an estimated-slope torque, which is calculated from a demand torque corresponding to a predetermined parameter and an estimated slope of a road surface, so that the feed-forward control portion outputs a feed-forward torque; and a feedback control portion for carrying out a feedback control based on the predetermined parameter to output a feedback torque; the acceleration control apparatus outputs a demand torque based on the feed-forward torque and the feedback torque in order to control an acceleration of the vehicle in a vehicle traveling direction, and the acceleration control apparatus further comprises: a reliability calculating portion for calculating reliability of the estimated slope; and a feedback torque correcting portion for correcting the feedback torque in such a way that a gain for the feedback control portion, which corresponds to an output of the feedback control portion with respect to an input thereof, is increased in response to a decrease of the reliability of the estimated slope calculated at the reliability calculating portion.
