Abstract
A brake control device is provided for a vehicle that includes a brake pedal, an electric booster, a master cylinder, a pedal depression force calculator, a pedal stroke sensor, a first target braking force portion calculator, a second target braking force portion calculator, a contribution degree setting section and a target braking force calculator. The contribution degree setting section sets the contribution degree of a first target braking force based on a pedal depression force to be greater than a contribution degree of a second target braking force based on a pedal stroke when a target braking force is estimated to be low. The target braking force calculator calculates the first target braking force portion and the second target braking force portion according to the contribution degrees and obtains the final target braking force by adding the first target braking force portion and the second target braking force portion.
