Abstract
A vehicular electrical braking device equipped with a control means for driving an electric motor and a lock mechanism, the electric motor pressing a friction member against a rotary member, and the lock mechanism applying parking brake. The control means comprises steps of: calculating an instruction pressure force on the basis of the amount of brake operation; calculating a parking pressure force on the basis of a parking signal; determining as a target pressure force the greater one of the instruction pressure force and the parking pressure force; adjusting the amount of power to be applied to the electrical motor such that an actual pressure force matches the target pressure force on the basis of the target pressure force and the actual pressure force; and controlling the operation of the lock mechanism on the basis of the actual pressure force.
