Abstract
An apparatus and method for controlling a braking-force distribution in a vehicle collision is used in a vehicle including at least one electric storage device and at least one motor-generator for driving and braking. When the vehicle decelerates or stops in response to a brake operation, regenerative cooperative brake control is performed in which a braking force of a frictional brake is reduced or eliminated while a braking force of a regenerative brake applied by the motor-generator is increased by an amount corresponding to the reduction in the braking force of the friction brake. When the vehicle collides, the apparatus reduces the braking force of the regenerative brake applied by the motor-generator and increases the braking force of the friction brake.
