Abstract
A method for determining a likely internal pressure for a master brake cylinder including: estimating/measuring a displacement path(s) of a brake input element configured on a master cylinder from initial position thereof; estimating/measuring a first hydraulic fluid volumetric flow rate of a hydraulic fluid of the braking system out of or into a first pressure chamber of the master cylinder, and of a second hydraulic fluid volumetric flow rate of the hydraulic fluid out of or into a second pressure chamber of the master cylinder; and determining the likely internal pressure for a master cylinder considering the estimated/measured displacement path(s), the estimated and/or measured first hydraulic fluid volumetric flow rate, and the estimated and/or measured second hydraulic fluid volumetric flow rate. Also described is a device for determining a likely internal pressure for a master brake cylinder, and an electromechanical brake booster, ESP control, and vehicle braking system.
