Abstract: An electric brake control apparatus includes: a clamping force acquisition unit configured to acquire a clamping force generated by moving a piston toward a pad through rotation of a motor; a lower-limit clamping force acquisition unit configured to acquire a minimum value of the clamping force required to maintain a stopped state of the rotor; an upper-limit clamping force acquisition unit configured to acquire a maximum value of the clamping force to move the piston away from the pad through a power of a power supply while maintaining the stopped state of the rotor, based on a state of a power supply; and a clamping force control unit configured to control the motor such that the clamping force is confined between the minimum value and the maximum value.

Abstract: A vehicle brake control device generates rear wheel braking torque by an electric motor by pressing a friction member against a rotating member rotating together with the rear wheel, reduces rear wheel braking torque by controlling the electric motor based on a target energization amount calculated from a slip state quantity of the rear wheel, and rapidly stops electric motor rotation motion based on an adjusted target energization amount calculated from the target energization amount and a slip state quantity of a front wheel.

Abstract: Each of a plurality of electric brake devices corresponds to one of a plurality of wheels and includes a motor. A brake ECU, which controls the electric brake devices, determines whether there is an overheated motor of which the temperature T is greater than or equal to a first set threshold value Tth1. Also, when there is only one overheated motor, the brake ECU reduces a current value Ix for the overheated motor at a more gradual gradient in the case where the temperature T of the overheated motor is low than in the case where the temperature is high.

Abstract: This electric braking device for a vehicle imparts to the wheels of the vehicle a braking torque in accordance with the output of an electric motor. A vehicle body-side electronic control unit calculates a command value for the output of the electric motor on the basis of the amount of operation performed on a braking operation member. A wheel-side electronic control unit adjusts the output of the electric motor on the basis of the command value. The vehicle body-side electronic control unit calculates the vehicle body speed on the basis of the wheel speed. The wheel-side electronic control unit adjusts the output of the electric motor so as to prevent an increase in slippage of the wheels on the basis of the vehicle body speed and the wheel speed.

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.
