There is provided a vehicle power steering control apparatus. A steering control unit sets a base assist torque Tb based upon a vehicle speed and a steering torque. When an obstacle ahead is detected by an image recognition device, the steering control unit calculates an overlapping ratio between the obstacle and the vehicle in the widthwise direction. When an absolute value of the overlapping ratio is larger than a predetermined threshold value, the steering control unit increases the base assist torque for correction, and when the absolute value is equal to or smaller than the predetermined threshold value, it decreases the base assist torque for correction. The steering control unit outputs the calculated value to a motor drive unit as a control quantity (assist torque).
