Abstract: The steering stability of a moving vehicle is maintained by measuring an actual yaw rate of the vehicle and determining a desired yaw rate of the vehicle. An output signal is produced in response to a comparison of the actual and desired yaw rates. The angle of steerable wheels of the vehicle is controlled in response to the output signal in a manner tending to substantially conform the actual yaw rate to the desired yaw rate, thereby maintaining vehicle stability. The steerable wheels are steered by a steering wheel, and are independently steered in response to the output signal. Alternatively, the steerable wheels are steered solely in response to the output signal.

Abstract: 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.

Abstract: 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.
