摘要： A vehicle brake control device generates rear wheel braking torque by an electric motor by pressing a friction member against a rotating member rotating together with the rear wheel, reduces rear wheel braking torque by controlling the electric motor based on a target energization amount calculated from a slip state quantity of the rear wheel, and rapidly stops electric motor rotation motion based on an adjusted target energization amount calculated from the target energization amount and a slip state quantity of a front wheel.

摘要： 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.

摘要： Rotational motion of a shaft member rotationally driven by a motor is converted by a screw member into translational motion of a pressing member. An outer periphery of a cap member is brought into slide contact with a first cylindrical part of the pressing member so that the cap member is relatively movable in an axial direction of the pressing member and is relatively unrotatable about its axis. An inner periphery of the cap member is brought into slide contact with a second cylindrical part of the shaft member so that the cap member is relatively movable in an axial direction of the shaft member and is relatively rotatable about its axis. The first cylindrical part, the second cylindrical part, and the cap member partition a storage chamber connected to one end of the screw member, and a lubricant for lubricating the screw member is filled inside the storage chamber.

摘要： When a braking operation amount is reduced, a stiffness value representing a ratio of variation in actual pressing force of a friction member to a variation in actual position of an electric motor are sequentially computed. The actual position when the stiffness value changes from being higher than or equal to a predetermined value to being lower than the predetermined value is stored as a candidate position. When a duration during which the stiffness value is lower than the predetermined value is shorter than a clearance corresponding value corresponding to a transmission member clearance in a state where the candidate position is stored, the candidate position is deleted. When the duration during which the stiffness value is lower than the predetermined value exceeds the clearance corresponding value, the stored candidate position is determined as a reference position at which the friction member and the rotary member begin contacting each other.
