摘要： A mount member is fixed to a support member by first and second fastening members, and a caliper is mounted to the mount member by first and second guide members. A motor axis of an electric motor and an axis of a shaft member configured to press a pressing member are different from each other. The electric motor is fixed to the caliper. When viewed from an axial direction of the first guide member, the motor axis is positioned inside a fastening quadrangle having four corners corresponding to positions of respective axes of, and is perpendicular to the axis, and the motor axis is orthogonal to a plane of the fastening quadrangle. As a result, there may be provided a vehicle electric braking device in which an axial direction dimension may be reduced to suppress an amplitude caused by vibration, and components sensitive to vibration influence are appropriately arranged.

摘要： In a vehicle brake control device for generating rear wheel braking torque by an electric motor, “slip suppression control of the rear wheel” for reducing rear wheel braking torque by controlling the electric motor is executed based on a slip state quantity of the rear wheel. Further, “sudden-stop control” for rapidly stopping electric motor rotation motion is executed based on a slip state quantity of a front wheel. The sudden-stop control is executed when rear wheel slip suppression control is not being executed. As the sudden-stop control, “control for changing an energization amount of the electric motor stepwise to an energization limit value set in advance corresponding to a deceleration direction of the electric motor” may be executed. Accordingly, it is possible to suppress excessive rear wheel slip due to inertia influences or the like of the electric motor when execution of the rear wheel slip suppression control is started.

摘要： An electric motor is controlled based on a target energization amount calculated based on an operation amount of a braking operation member. Based on the operation amount, it is determined whether or not an inertia compensation control for compensating for the influence of the inertia of a brake actuator is necessary. When the inertia compensation control is determined to be necessary, an inertia compensation energization amount compensating for the influence of the inertia of the brake actuator is calculated using a time-series pattern set in advance based on the maximum response of the brake actuator. Using the inertia compensation energization amount, the target energization amount is calculated. The vehicle brake control device causes an electric motor to generate a braking torque and appropriately compensates for the influence of the inertia of the entire device including the inertia of the electric motor.

摘要： Based on a difference between target and actual values of a friction member force pressing a brake disc, feedback control over the pressing force is executed. As the actual value, a “limit pressing force (Fbs) obtained by placing a limitation on a temporal change amount of the Fba based on a limit value (Lmt)” is used. The limit value (Lmt) is set based on an electric motor speed (dMkt, dMka), a wheel speed (Vwa), and a temporal change amount (ΔTmp) of the friction member temperature. The Lmt is set to increase as the dMkt (dMka) increases and the temporal change amount (ΔTmp) of the temperature increases, and to also increase as the wheel speed (Vwa) decreases. Thus, even when a rotating member (brake disc) is deformed, braking torque control can be appropriately executed without accelerating a fluctuation of a braking torque on the wheel.

摘要： Electric motor control is based on a target energization amount calculated using a braking operation member operation amount. A state quantity is acquired as an actual value, indicating an actual actuation state of a movable member located in a power transmission path from the electric motor to a friction member. Using the operation amount, it is determined whether or not inertia compensation control is necessary, which compensates for the inertia influence of a brake actuator during electric motor deceleration. “A target value corresponding to the actual value” is determined as a reference value, which is calculated based on the operation amount at a time when inertia compensation control is necessary. Based on the actual and reference values, “an inertia compensation energization amount for decreasing the target energization amount to compensate for the influence of inertia” is calculated, and the target energization amount is adjusted using the inertia compensation energization amount.

摘要： 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.
