Abstract: A brake control device includes a processor that controls a brake device of a vehicle. The processor receives a first braking request indicating first braking force by the brake device which is requested from an application that implements a driver assistance function of the vehicle. The processor receives a second braking request indicating second braking force by the brake device which is requested depending on an operation amount of a brake pedal of the vehicle. The processor starts override control when the processor receives the second braking request while the processor controls the brake device in accordance with the first braking request.
