摘要： A brake system capable of accurately controlling a braking force includes a first and second brake devices that have different control accuracies, and a brake control device that controls a braking force of the first and second braking devices according to a required braking force. The brake control device has a first control mode in which the braking force of the first brake device is controlled to be smaller than the braking force of the second brake device, and a second control mode in which the braking force of the first brake device is increased rather than the first control mode. The second brake device is controlled so that a sum of the braking force of the first brake device and the braking force of the second brake device matches the required braking force.

摘要： 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.
