A method for checking a total distance travelled by a motor vehicle and displaying the total distance in the motor vehicle includes: detecting a change in a component of a control device of the motor vehicle, change in the component being irreversible and taking place over a time period; assigning the magnitude and/or type of the change in the component to a comparison distance, related to the time period, travelled by the motor vehicle; comparing a distance detected by an odometer of the motor vehicle during the time period with the comparison distance; and an operator of the motor vehicle retrieving a result of the comparison or the operator receiving an automatic transmission of the result of the comparison.

A method for operating a combustion machine, such as an internal combustion engine, has the following steps: provision of a combustion machine for producing thermal energy; operation of the combustion machine, and thereby burning fuel to obtain the thermal energy; detection of the concentration of at least one pollutant, which is produced during the combustion, in the surroundings of the combustion machine; regulation of the operation of the combustion machine, in which a characteristic variable of the combustion machine is set according to the detected concentration in such a way that the emission of the pollutant is reduced.

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.

Brake value signal transmitter for an electrically controlled and activated brake system

The brake system includes a pedal unit through which operations of the brake pedal of the motor vehicle are detected with one or more sensors and desired values of the brake application force are generated according the driver requirement. The system also includes electrically actuated brake actuators at the wheels of the motor vehicle. An electronic central controller evaluates the sensor signals and generates control signals for additional brake functions. Data blocks are exchanged in a predefined cyclically repeating time pattern over a data bus connecting the pedal unit, the brake actuators, and the central controller. Over an additional signal line connecting together the pedal unit, the brake actuators and the central controller, the desired value for the brake application force is transmitted from the pedal unit to the brake actuators and the central controller and data are exchanged concerning the status of the connected devices.

Brake system for a motor vehicle and method for transmitting data in an electrically controlled brake system for a motor vehicle

The brake system of a motor vehicle has a wheel-brake actuator for each wheel brake. The wheel-brake actuator, which is controlled by the brake pedal via electric lines, presses the brake linings against the brake disk. A force sensor senses the circumferential force produced by the brake torque. The output signal of the sensor is taken into account as the current value by the control of the wheel-brake actuator when setting the contact force between the brake linings and the brake disk.
