Embodiment Construction

[0016] Hereinafter, various exemplary embodiments of the present invention will be described with reference to the accompanying drawings. figure 1 The structure of a vehicle brake control apparatus according to the present invention is shown. figure 2 Indicates the structure of a vehicle braking system equipped with such a control device.

[0017] refer to figure 2 , the structure of the braking system of the vehicle will be described. The vehicle has wheel cylinders 25-28 for applying braking forces to the front right wheel FR, front left wheel FL, rear right wheel RR, and rear left wheel RL, respectively. Braking of the vehicle is performed by wheel cylinders 25-28.

[0018] A brake pedal 10 for operating the brake system is connected to a piston rod of a master cylinder 11 . A brake switch 40 for detecting the operating state of the brake pedal 10 is connected to the brake pedal 10 .

[0019] Two fluid lines, including one for the front right wheel FR and the rear le...

Abstract

A vehicular brake control apparatus performs braking force limiting control for limiting, if the vehicle is in a predetermined driving state, braking forces applied to rear wheels of the vehicle in comparison with the braking forces applied to the front wheels(S4). If it is judged during the braking force limiting control that the amount of braking operation by the driver has increased(S5), the apparatus increases the braking forces applied to the rear wheels(S6).

Description

technical field [0001] The present invention relates to a vehicle brake control apparatus and a vehicle brake control method that limit the braking force applied to the rear wheels of the vehicle compared with the braking force applied to the front wheels of the vehicle. Background technique [0002] There is known a brake control apparatus that limits the braking force distributed to the rear wheels during a braking operation at high speeds to prevent the rear wheels from locking. According to Japanese Patent Application Laid-Open No. 5-213169, if the deceleration has become equal to or higher than a predetermined value at the time of braking, the fluid pressure for transmitting the braking force to the rear wheels is maintained. This prevents the rear wheels from locking before the front wheels lock, and effectively keeps the vehicle from sliding sideways when braking. [0003] However, according to the above-mentioned apparatus, once the predetermined deceleration is rea...
