Braking force retaining unit
ActiveUS20060108868A1Smooth startReducing feeling of abruptnessBraking action transmissionBrake action initiationsEngineeringWheel cylinder
A braking force retaining unit has a cut-off valve and a control unit. The cut-off valve retains predetermined brake hydraulic pressure at the wheel cylinders until a predetermined releasing condition is established even after the depression of a brake pedal is released when a vehicle is stopped, whereas when the predetermined releasing condition is established, the brake hydraulic pressure so retained is released, when the depression of the brake pedal is released, the control unit controls the cut-off valve so as to retain the brake hydraulic pressure while reducing the retained brake hydraulic pressure at a first reduction speed. When the predetermined releasing condition is established, the control unit controls the cut-off valve so as to allow the brake hydraulic pressure retained at the wheel cylinders to be reduced at a second reduction speed which is faster than the first reduction speed.
