摘要： A brake controller includes a control circuit that calculates target braking force every predetermined period, in accordance with feedback control on at least acceleration or speed of a vehicle steered for parking; and a filter circuit that outputs, to a brake device, output braking force obtained by applying a low-pass filter having a predetermined time constant to the target braking force when the amount of change in the target braking force over time is within a predetermined tolerable range. When the amount of change is outside the tolerable range, the filter circuit outputs, to the brake device, the target braking force as output braking force or outputs thereto output braking force calculated by correcting smoothed target braking force, which is obtained by applying the low-pass filter to the target braking force, so that a difference between the smoothed target braking force and the target braking force is within the tolerable range.

摘要： A step determination device includes an operation amount sensor that detects an operation amount of a braking operation member, and a controller that determines a step by using the wheel speed and the operation amount. In the step determination device, the controller calculates an actual variable amount by using the wheel speed, calculates an estimated variable amount corresponding to the actual variable amount by using the operation amount, and executes the determination of the step by using the actual variable amount and the estimated variable amount. For example, the controller determines the presence of the step when the deviation between the actual variable amount and the estimated variable amount is not less than a predetermined value, and determines the absence of the step when the deviation is less than the predetermined value.

摘要： A vehicle brake control device includes an electric motor controlled based on a target energization amount calculated based on an operation amount (Bpa) of a braking operation member. Based on the operation amount (Bpa), 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 for compensating for the influence of the inertia of the brake actuator is calculated based on a time-series pattern set in advance based on the maximum response of the brake actuator. Based on the inertia compensation energization amount, the target energization amount is calculated. The vehicle brake control device is thus able to generate a braking torque that 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 (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.

摘要： An abnormality determining apparatus is applied to a vehicle motion control apparatus in which a vehicle behavior sensor (yaw rate sensor, etc.) is integrally mounted to an integrated unit that is integrally composed of an HU (hydraulic unit) and ECU. In this abnormality determining apparatus, the pattern of the vibration noise appearing on the output from the vehicle behavior sensor (output from yaw rate sensor Yrfilpc, etc.) is obtained when various actuators such as motor, solenoid valves, or the like, that are mounted to the HU, are operated with a predetermined pattern for a primary check for the HU. When the pattern of the vibration noise is not within the predetermined normal pattern range, it is determined, according to the abnormal manner of the pattern of the vibration noise, that the abnormality of the vehicle behavior sensor, abnormal operation of the actuator in the HU, or the like occurs.
