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.
Claims8
In combination with an electrically controlled and activated brake system, a brake value signal transmitter to be connected to a brake pedal of a motor vehicle and sensing movements of the brake pedal with at least one sensor and converting the movements into electrical signals, the brake value signal transmitter comprising:
- a cylinder having an interior wall defining an interior formed therein;
- a piston disposed in said interior of said cylinder;
- a rotatably mounted pressure rod connecting the brake pedal to said piston;
- and
- said interior of said cylinder defining a pressure space filled with a gas and at least partially with a hydraulic oil, the hydraulic oil bounding a gas-filled part of said pressure space with a variable volume, and the gas being compressed by said piston when the brake pedal is activated and causing a reaction force to act on the brake pedal.
