<p><P>PROBLEM TO BE SOLVED: To stabilize body attitude or vehicle characteristics by suppressing the influence of driver operation disturbance or road surface disturbance or the like. <P>SOLUTION: Various vibrations on a body spring are estimated by a body vibration model, and a required engine torque equivalent to a required driving force is corrected so that pitching vibration being one of the vibrations of the body spring can be suppressed. Concretely, traveling resistance disturbance estimated by a front wheels traveling disturbance estimating part 2d is added to estimated driving shaft torque estimated by an estimated driving shaft torque calculating part 2b so that a current driving force can be calculated, and pitching vibration corresponding to the current driving force is calculated from the status equation and output equation of a driving model on the body spring. Then, a correction value for quickly turning the pitching vibration expressed with the output equation into zero is calculated, and a basic request engine torque calculated by a basic request engine torque calculating part 2a is corrected based on the correction value. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
