An object of the present invention is to provide a brake control device and a brake system capable of braking with a shortened braking response when shifting from non-braking to braking. A brake control device 10 includes a command value calculation unit 4 that calculates an operation command value required to make a pressing force by which a brake pad 11a is pressed against a brake disc 11b reach a target thrust value. The command value calculation unit 4 includes: a clearance command calculation unit 43 that calculates a command value required for contact between the brake pad 11a and the brake disc 11b; and a thrust command calculation unit 40 that calculates a command value required for reaching the target thrust from a state where the brake pad 11a and the brake disc 11b are in contact with each other. When calculating the operation command value from a state where the brake pad 11a and the brake disc 11b are separated, the command value calculation unit 4 calculates the operation command value by integrating the command value calculated from the clearance command calculation unit 43 and the command value calculated from the thrust command calculation unit 40.

The controller may be configured to control the hydraulic pressure supply device to supply the hydraulic pressure to the wheel cylinder through the flow path, and in response to a change in a gear position of a transmission of the vehicle, to control at least one of the hydraulic pressure supply device and the at least one valve to maintain a hydraulic pressure of the wheel cylinder or a hydraulic pressure of the flow path for a first reference time after the change in the gear position.

A method for controlling an activation state of a braking-torque assistance system for reducing intake of braking energy in a service-brake system of a vehicle includes capturing and evaluating a plurality of demand indications for a startup of the braking-torque assistance system. If the evaluation of the captured plurality of demand indications reveals a demand for the startup of the braking-torque assistance system, a plurality of operating conditions of the service-brake system are captures and evaluated over a monitoring period. If, in turn, the evaluation of the captured plurality of operating conditions reveals that an overheating of the service-brake system is imminent, the braking-torque assistance system is actuated and one or more deactivation conditions of the braking-torque assistance system are checked. If the deactivation conditions are satisfied, the braking-torque assistance system is deactivated.
