Abstract
A method for brake pressure apply in a hydraulic brake system includes commanding a cage clearance reduction phase and commanding a wheel control phase subsequent to the cage clearance reduction phase. Accordingly, the cage clearance is reduced prior to entering the wheel control phase. A method for cage clearance reduction in a hydraulic brake system for roll stability control is also provided.
Claims12
A method for brake pressure pulsing to achieve cage clearance reduction in a hydraulic brake system comprising the steps of:
- commanding a series of pressure builds and pressure releases while a measured brake pressure is greater than zero and until a brake system inertia is overcome;
- and
- commanding a wheel control phase subsequent to commanding the series of pressure builds and releases.
A method for cage clearance reduction in a hydraulic brake system for roll stability control comprising:
- performing at least one pressure build while a measured brake pressure is greater than zero;
- and
- performing at least one pressure release while the measured brake pressure is greater than zero;
- wherein cage clearance is substantially minimized by said at least one pressure build and at least one pressure release while a measured brake pressure is greater than zero and until a brake system inertia is overcome.
