Abstract: 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.

Abstract: An electric braking device includes: an electric motor for pressing a friction member against a rotary member that rotates integrally with a vehicle wheel; a lock mechanism for locking rotation of the electric motor and applying a parking brake in accordance with operation on a parking switch; and a control for driving the electric motor and the lock mechanism. The control increases the electricity amount sent to the electric motor when a pressing force is less than a preset lower value at the time the parking switch is switched from off to on, starts actuating the lock mechanism when the pressing force equals or exceeds the lower value, and, when the pressing force is greater than a preset upper value greater than or equal to the lower value, starts actuating the lock mechanism when the pressing force equals or exceeds the upper value.

Abstract: 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.
