Patent ID: 8388071

Claim:
A braking controller, used for braking control of a vehicle, which is capable of applying a brake to rear wheels by regenerative braking of an electric motor, comprising: a braking force distribution means for controlling distribution of a required total braking force provided by a driver's operation input, and a road-surface friction coefficient detection means for detecting a road-surface friction coefficient, wherein said braking force distribution means distributes said required total braking force by regeneration distribution, said regeneration distribution is required to be within the rear-wheel dominant range in which a distribution ratio is inclined toward the rear wheels when compared to an ideal distribution which distributes said required total braking force to enable front wheels and the rear wheels to simultaneously lock, said regeneration distribution is also required to be within the range not greater than a rear-wheel locking limit braking force that enables the rear wheels to lock in relation with the road-surface friction coefficient detected by said road-surface friction coefficient detection means, and a rear-wheel braking force change ratio, which is a rear-wheel braking force change ratio with regard to the change of a front-wheel braking force associated with the change of the required total braking force, is required to always be positive.
