Braking force control apparatus and braking force control method for vehicle

摘要

A vehicle braking force control apparatus includes a controller that performs a front-rear braking force distribution control in which the braking forces applied to the left and right rear wheels are controlled individually so that a wheel speed of each of the rear wheels is equal to a target wheel speed of the rear wheel, which is set based on a predetermined relationship between the wheel speed of the front wheel and the target rear wheel speed of the rear wheel, and that corrects the target wheel speed of at least one of the left and right rear wheels, based on a parameter related to a change rate of load shift amount in a vehicle transverse direction, so that the target wheel speed of the rear wheel on a ground contact load increase side is less than the target wheel speed of the rear wheel on a ground contact load decrease side.

1. A vehicle braking force control apparatus comprising a controller
that performs a front-rear braking force distribution control that distributes a braking force to front wheels and rear wheels, wherein in the front-rear braking force distribution control, the braking forces applied to the left and right rear wheels are controlled individually so that a wheel speed of each of the rear wheels is equal to a target wheel speed of the rear wheel, which is set based on a predetermined relationship between the wheel speed of the front wheel and the target wheel speed of the rear wheel, and that corrects the target wheel speed of each of the left and right rear wheels, based on a parameter that is related to a change rate of amount of load shift in a vehicle transverse direction, such that the target wheel speed of the rear wheel on a ground contact load increase side is less than the target wheel speed of the rear wheel on a ground contact load decrease side, wherein the controller corrects the target wheel speed of each of the left and right rear wheels so that a magnitude of a correction amount for correcting the target wheel speed of the left rear wheel and the magnitude of a correction amount for correcting the target wheel speed of the right rear wheel are equal to each other.
