Abstract
In an electric parking brake control apparatus for controlling an electric actuator for driving parking brakes, a dynamically estimated road surface inclination is estimated based on a running state of a vehicle while the vehicle is running, and a statically estimated road surface inclination is estimated based on an acceleration acting on the vehicle after the vehicle is stopped. In the event that the statically estimated road surface inclination is larger than the dynamically estimated road surface inclination after the vehicle is stopped, a braking force of the parking brakes is increased to be larger than a braking force that is set based on the dynamically estimated road surface inclination.
