Abstract
A brake value signal transmitter that is to be connected to a brake pedal of a motor vehicle senses activations of the brake pedal with a plurality of sensors and converts them into electrical signals. The brake pedal is connected via a rotatably mounted pressure rod to a piston that can be displaced in the interior of a cylinder. A pressure space that is filled with a gas, has a variable volume, and can be filled at least partially with hydraulic oil is provided in the cylinder. The gas is compressed by the piston when the brake pedal is activated, and in the process increases a reaction force acting on the brake pedal.
