Patent ID: 7050896

Claim:
A device for controlling electrically-driven power steering apparatus of a vehicle, the device calculating a target value of steering assist torque based upon at least steering torque; calculating a target value of steering converging torque based upon at least a steering velocity; calculating a target value of total modification torque to be generated with the power steering apparatus based upon at least the target values of the steering assist torque and steering converging torque; and controlling the power steering apparatus based upon the target total modification torque; characterized in that the device further calculates a target value of behavioral deterioration-suppressing torque for suppressing steering causing a vehicle behavioral deterioration when the vehicle falls into oversteered or understeered conditions, and renders a degree of contribution of the target value of the behavioral deterioration-suppressing torque to the target value of the total modification torque higher than a degree of contribution of the target value of the steering converging torque to the target value of the total modification torque when a predetermined condition is satisfied.
