Abstract
Official abstract text for this publication.
Methods and systems are provided to reduce a hard brake pedal feel. A brake control variable is adjusted in anticipation of a hard pedal condition to increase hydraulic brake line pressure and maintain a normal pedal feel. A pedal force is inferred from brake line pressure relative to brake booster vacuum.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for improving brake pedal feel, comprising: inferring, via an electronic controller, an impending hard pedal condition, before the hard pedal condition occurs, based on a brake booster vacuum relative to a hydraulic brake line pressure; and in response to the inference, increasing the hydraulic brake line pressure via adjustments to a brake system component to maintain a ratio of pedal force to brake pedal displacement at less than a thresho…
