Estimating the term…
The invention relates to a method for operating a braking system, including a brake booster, which is divided into at least one vacuum chamber and at least one working chamber by at least one movable partition, wherein at least one vacuum chamber is connected, or can be connected, to a vacuum source for creating a vacuum, and further including at least one sensor, which detects at least one variable such as travel and/or angle and/or force of a brake pedal actuation and/or a brake pressure that is built up in at least one main brake cylinder connected to the brake booster in accordance with a brake pedal actuation. According to the invention, the remaining vacuum in at least one vacuum chamber is estimated on the basis of at least one of the detected variables by considering actuations already performed. The invention further relates to a braking system and to the use thereof.
A method for operating a brake system having a brake booster which is divided into at least one negative-pressure chamber and at least one working chamber by at least one movable partition, wherein at least one negative-pressure chamber is or can be connected to a negative-pressure source for the build-up of a negative pressure, and having at least one sensor which detects at least one variable such as travel and/or angle and/or force of a brake pedal actuation and/or a brake pressure that is built up, in accordance with a brake pedal actuation, in at least one master brake cylinder that is connected to the brake booster, wherein an estimation of the remaining negative pressure in at least one negative-pressure chamber is performed on the basis of at least one of the detected variables taking into consideration past brake pedal actuations.
