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: 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.

Abstract: 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.

Abstract: After a vehicle has entered a curve, a deviation (Sch) between a target turning state quantity Td and an actual turning state quantity Ta is computed. In a stage in which Sch does not reach a predetermined value after the vehicle has entered the curve, the possibility of the vehicle traveling in the curve is judged to be low, and the reliability of the curve information Rc, Pc is judged to be low. In this case, a determination for prohibiting execution of control (So=0) is made. In a stage after Sch has reached the predetermined value, the possibility of the vehicle traveling in the curve is judged to be high, and the reliability of the curve information Rc, Pc is judged to be high. In this case, a determination for permitting execution of the control (So=1) is made. Deceleration control is started and executed only when a control start condition is satisfied, and the determination for permission is made. Accordingly, even when the control start condition is satisfied, the deceleration control is not started, if the prohibition determination is made. Thus, the reliability of the curve information based on map information on the vehicle is evaluated reliably, and the deceleration control within the curve can be prevented from being unnecessarily executed on the basis of curve information whose reliability is low.

Abstract: An anti-collision control is provided under circumstances where it is determined that there is a risk of collision between a host vehicle and a preceding vehicle. The anti-collision control utilizes host vehicle information, preceding vehicle information, and surrounding road conditions to determine whether or not a collision with the preceding vehicle can be avoided through a steering operation. If avoidance is determined to be possible, then a shift-hold control is applied to the AT, whereas if avoidance is determined to be impossible, then a down-shift control is applied to the AT.
