    Abstract: A vehicle electric braking device wherein: a first degree of contribution associated with the actual pressing force value and a second degree of contribution associated with an estimated pressing force value, are determined based on operation amount of a braking operation member; the second degree of contribution is determined to be larger than the first degree when the operation amount is small; the first degree of contribution is determined to be larger than the second when the operation amount is large; a combined pressing force is calculated based on a value obtained by accounting for the first degree of contribution in the actual pressing force value and a value obtained by accounting for the second degree of contribution in the estimated pressing force value; and an electric motor target power supply amount is calculated based on the combined pressing force and a target pressing force calculated from the operation amount.

    Abstract: A brake actuator converts the rotation of an electric motor into a linear movement to transmit the linear movement to a piston and, by the piston, presses a brake pad against a disc rotor to generate a brake force on a wheel. When a braking operation is finished, a brake control device rotates the electric motor in a direction corresponding to a return direction and detects a rotational position of the electric motor when the brake force is removed. The brake control device further rotates the electric motor in the return direction and restricts the rotation of the electric motor by a lock mechanism after adjusting the rotational position of the electric motor so that the difference between the rotational position when the brake force is removed, and the present rotational position of the electric motor comes into a reference rotational range.

    Abstract: A vehicle brake apparatus capable of preventing abnormal vibration due to thickness variations in a disc rotor includes a motor drive unit configured to control the motor which presses the brake pad against the disc rotor, a brake pressure detection unit for detecting a braking pressure for pressing the brake pad, and a wheel speed sensor for detecting a rotation speed of the disc rotor. If an amount of variation in the detection values detected by the brake pressure detection unit during one rotation of the disc rotor exceeds a variation amount determination threshold value and a detection value variation frequency has a correlation with the rotation speed of the disc rotor and the detection value variation frequency exceeds a variation frequency determination threshold value, the motor drive unit controls the motor in inverted phase to the variation in the detection values.
