Abstract
In a vehicle driving force control apparatus for controlling a driving force of the vehicle to achieve a target acceleration or a target vehicle speed, a running resistance estimating section calculates an estimated running resistance. A target acceleration modifying section modifies the target acceleration with the estimated running resistance and thereby decreases the target acceleration with increase in the estimated running resistance.
