| 摘要 |
The invention relates to a pedal simulation device for simulating the reaction behaviour of a pedal, in particular of a brake pedal of a vehicle brake system, comprising a cylinder, a piston disposed displaceably inside the cylinder and coupled to the pedal and delimiting a working chamber inside the cylinder, a resetting element which, upon an actuation of the pedal, exerts a resetting force on the pedal, and a modelling device, which is fluidically connected to the working chamber, for influencing the reaction behaviour of the pedal. In the invention, for achieving the reaction behaviour it is provided that, upon an actuation of the pedal, by means of the modelling device a vacuum, which is arising or has arisen in the working chamber, is built up.
