Abstract
A vehicle attitude control apparatus has suspensions Sfl, Srl, Sfr, and Srr that suspend each of front-left, rear-left, front-right and rear-right wheels Wfl, Wrl, Wfr, and Wrr; electric motorsandthat independently drive each of four wheels; lateral acceleration sensor; and controller. The controllercalculates the roll angle and roll direction of a vehicle body BD by using the detected lateral acceleration. Further, the controllerincreases or decreases the driving torques generated by the electric motorstoby a driving torque changing amount in accordance with the calculated roll angle and roll direction. With the increase or decrease in the driving torques generated by the electric motorstoby the driving torque changing amount, downward force is generated on the vehicle body moving up upon the vehicle roll (at respective instant centers determined by the suspensions at the side where the vehicle body moves up), and upward force is generated on the vehicle body moving down upon the vehicle roll (at respective instant centers determined by the suspensions at the side where the vehicle body moves down).
