Control device for a motor vehicle having an input equipped for processing signals of different types of sensors

A control device (42) as set forth in claim wherein said pull-up switch (44) lies in a series with a pull-up resistor (36) and said pull-down switch (46) lies in a series with a pull-down resistor (26).

A method for adapting a control device (42) to a sensor (10, 34) that is to be connected to the control device (42), wherein the control device (42) is for use in a motor vehicle and includes at least one input that has an input port (12), at least one input channel (20, 38), and an input circuitry (43) and receives signals from the sensor (10, 34) via the input port (12) and sends the signals via the input circuitry (43) to the input channel (20, 38), wherein said method comprises a step of:

• connecting the input port (12) to a defined voltage via a resistor either by a first pull-up switch (44) that can be actuated by the control device (42) controlling connection of the input port (12) to a high voltage and a second pull-down switch (46) that can be controlled by the control device (42) controlling connection of the input port (12) to a low voltage.
