Apparatus for determining a method and a brake master cylinder pressure estimation for determining the brake master cylinder pressure estimation

摘要

[object of the present invention relates to a method for determining the brake master cylinder estimated internal pressure, also relates to an apparatus for determining the brake master cylinder estimated internal pressure. The invention further electromechanical brake booster, ESP control mechanism, and a brake system for a vehicle. A step of evaluating and / or measuring A displacement distance from the starting position of the brake input element disposed in the brake system of the brake master cylinder (10) (12,14) (s), wherein the first pressure chamber of the brake master cylinder (10) and the first hydraulic fluid volume flow of the hydraulic fluid of the braking system and out from (10a) (q _MC1 ), the brake step to evaluate and / or measurement and a second hydraulic fluid volume flow of the hydraulic fluid (q _MC2 ) into and out from the second pressure chamber (10b) of the master cylinder (10) When, at least, evaluation and / or measured the displacement distance (s), evaluated and / or measured first hydraulic fluid volume flow and (q _MC1 ), evaluation and / or measured second hydraulic fluid volume flow (q _MC2 ) and in consideration of, and a step of determining the brake master cylinder estimation pressure.FIELD 2b
