PROBLEM TO BE SOLVED: To effectively reduce discomfort that an occupant feels when a vehicle is braked and stopped by controlling a braking force to reduce a rapid change in forward-rearward acceleration of the vehicle at braking and stopping of a vehicle. SOLUTION: A target deceleration Gt of the vehicle is calculated on the basis of brake operating amount of a driver (S20). When it is determined that the vehicle is in a braked and stopped condition (S40, 50), a gain Kg for reducing the target deceleration is calculated so as to be decreased with a decrease in a ratio V/Gbx of a vehicle speed V to the deceleration Gbx of the vehicle (S80), a ratio of a rear wheel distribution Krs of the braking force is calculated to be decreased with a decrease in the ratio V/Gbx of the vehicle speed V to the deceleration Gbx of the vehicle (S90), the target deceleration Gta of the vehicle after correction is calculated as a product of the gain Kg for reducing the deceleration and the target deceleration Gt of the vehicle (S100), and the braking force of each wheel is controlled so that the target deceleration Gta of the vehicle after correction may be attained by the ratio of the rear distribution Krs of the braking force (S110, 120).
