<p>The present invention reduces the difference in braking target values to brake operation by the same pedal pressure at a low braking target value frequently used during usual running by a driver, and prevents a strange feeling of the brake operation given to the driver. A braking force control device for a vehicle is provided with a brake pedal (1), a motor booster (2), a master cylinder (3), a pedal pressure calculation unit (60), a pedal stroke sensor (18), a first target braking force calculation unit (65), a second target braking force calculation unit (66), a contribution degree set unit (63), and a target braking force calculation unit (67). The contribution degree set unit (63) so sets that the lower target braking force is estimated to be, the larger the contribution degree (1-ß) of first target braking force based on pedal pressure is than the contribution degree (ß) of second target braking force based on a pedal stroke. The target braking force calculation unit (67) calculates the first target braking force and the second target braking force in accordance with the contribution degrees (1-ß), (ß), and obtains final target braking force by adding the first target braking force and the second target braking force.</p> |
