  • Publication number: 20240092321
    Abstract: A control device is applied to a friction brake device of a vehicle. The friction brake device produces a friction brake force in the vehicle by starting driving of an electric motor. The control device includes a motor control unit configured to control the electric motor. The control device includes an acquisition unit configured to acquire an index value corresponding to a magnitude of a target value of the friction brake force. A value for determining a magnitude of the index value is set as a limit determination value. The motor control unit limits an increase speed of the number of rotations of the electric motor if the index value is equal to or less than the limit determination value, and releases the limit if the index value exceeds the limit determination value.

  • Patent number: 11807215
    Abstract: A brake control device is applied to a vehicle including a regenerative generator. The brake control device includes a pressure adjustment unit that includes an electric pump and a pressure adjustment valve, and that adjusts adjustment liquid pressure of a pressure adjustment fluid path between the electric pump and the pressure adjustment valve; and a controller that controls the electric pump and the pressure adjustment valve. The controller, before starting a replacement operation to replace a regenerative braking force by the regenerative generator with a friction braking force by the adjustment liquid pressure, performs preceding pressurization to increase the adjustment liquid pressure from “0” and maintain the adjustment liquid pressure at predetermined liquid pressure, and after performing the preceding pressurization, increases the adjustment liquid pressure more than the predetermined liquid pressure by increasing a rotation speed of the electric pump, and then execute the replacement operation.
