Abstract
A driving force controller for an electric vehicle includes a feed-forward compensator for computing a second target driving force so as to suppress overshooting of an actual driving force that is actually outputted, with respect to a first target driving force requested by a driver, the feed-forward compensator includes a first transfer function expressing a characteristic that the actual driving force becomes a predetermined response with respect to the first target driving force; and an inverse of a second transfer function approximately expressing a transmission characteristic between a input target driving force and the actual driving force in a control system except the feed-forward compensator.
