<p><P>PROBLEM TO BE SOLVED: To provide a control device for a vehicle stabilizing the behavior of the vehicle with respect to input from a road surface. <P>SOLUTION: In the vehicle 10 configured as a rear wheel drive vehicle and configured to vary distribution of lateral driving force by a driving force distribution device 330, an ECU 100 performs control over compensation of input from the road surface. In the control, front wheel lateral force F<SB>yf</SB>and rear wheel lateral force F<SB>yr</SB>are calculated based on a front wheel road surface input value D<SB>fin</SB>obtained by eliminating influence of the amount of steering strokes D<SB>st</SB>from the amount of front wheel strokes D<SB>f</SB>, and a yaw moment M<SB>y</SB>applied to the vehicle 10 is calculated. Meanwhile, after the yaw moment M<SB>y</SB>is calculated, corrected driving forceΔF<SB>1</SB>for suppressing yaw vibration of the vehicle 10 by the yaw moment M<SB>y</SB>is calculated. The corrected driving forceΔF<SB>1</SB>is subtracted from left rear wheel driving force F<SB>xrl</SB>in order to apply a yaw moment in a direction opposite to the yaw moment M<SB>y</SB>to the vehicle 10, and added to right rear wheel driving force F<SB>xrr</SB>. As a result, a change in the behavior of the vehicle in a yaw direction is suppressed. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
