Abstract
Official abstract text for this publication.
A method that compensates for fluid pressure variations in a vehicle brake system so that the fluid pressure, brake torque and/or brake force at the wheel more accurately reflects that requested by the driver. In an exemplary embodiment, the method determines the braking intent of the driver, determines a current stage of the braking event (e.g., an apply stage, release stage, etc.), uses the braking event stage and the driver braking intent to select a pressure compensation, and uses the pressure compensation to generate compensated brake command signals for operating the vehicle brake system. This method is well suited for use with brake-by-wire systems, such as an electrohydraulic braking (EHB) system.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for operating a vehicle brake system, comprising the steps of: (a) determining a driver braking intent; (b) determining a pressure compensation that compensates for fluid pressure variations in a master cylinder of the vehicle brake system, wherein the pressure compensation is determined with the use of empirically derived data accounting for imperfections in the operation of the master cylinder resulting in fluid pressure variations therein…
