Abstract: A braking force control method that is applied to a vehicle in which regenerative braking force and friction braking force are applied to the front wheels. When the braking slip quantity of one of the front wheels that is supplied with regenerative braking force exceeds a reference value, with the instance being a reference time point, the friction braking force of the front wheels is controlled so as to increase while the regenerative braking force being controlled so as to be a provisional target regenerative braking force that is lower by a prescribed value than the regenerative braking force of the front wheels at the reference time point. When a decision is made that a prescribed period of time has passed since the reference time point, the regenerative braking force is gradually decreased and the friction braking force is gradually increased.
