Abstract
An electric parking brake control apparatus for controlling an electric actuator for driving a parking brake is provided with: an inclination determination unit for determining an inclination of a road surface based on at least a change of a vehicle speed; and a braking force setting unit. The braking force setting unit sets a braking force of the parking brake to a slope braking force which is larger than a flat ground braking force set when the vehicle is stopped on a flat ground, according to an inclination of the road surface which is determined by the inclination determination unit. Moreover, in the event that the vehicle is stopped again without experiencing a running over a predetermined vehicle speed after braking with the slope braking force has been cancelled, the braking force setting unit sets the braking force to the slop braking force.
