Abstract:
A braking force control apparatus of a motor vehicle including (a) first and second regenerative braking devices that are operable to effect regenerative braking with respect to front wheels and rear wheels, respectively, and (b) a friction braking device that is operable to effect friction braking with respect to each of the front wheels and the rear wheels, comprising:a controller that: calculates a first target braking force of the front wheels and a second target braking force of the rear wheels, based on a braking requirement made by a driver of the vehicle and a ratio of braking forces of the front wheels and the rear wheels; and initially causes the first and second regenerative braking devices to generate regenerative braking forces at the front wheels and the rear wheels, and then, if necessary, causes the friction braking device to generate a friction braking force at each of the front wheels and rear wheels, so that a total braking force applied to the front wheels and a total braking force applied to the rear wheels are controlled to the first target braking force and the second target braking force, respectively.
