  • Patent number: 8406952
    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.

  • Patent number: 7908071
    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.
