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.

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： Based on a difference (ΔFb) between a target value (Fbt) and an actual value (Fba) of a friction member force for pressing a brake disc, a feedback energization amount (Ipt) is calculated using a proportional gain smaller than an ultimate sensitivity gain. If ΔFb falls within a fluctuation range of torque ripple, a first compensation energization amount (Ibt) is calculated using a proportional gain larger than the ultimate sensitivity gain, and if ΔFb falls outside the fluctuation range, the first compensation energization amount (Ibt) is calculated to be constant. A second compensation energization amount (Ift) is calculated based on a calculation characteristic that is preset based on a torque fluctuation over a predetermined range of an electric motor position and based on an actual position of the electric motor. An indication energization amount calculated according to Fbt is adjusted by Ipt, Ibt, and Ift to calculate a target energization amount.
