Abstract:
The invention pertains to a device for acquiring signals from sensors (1) installed in a motor vehicle, where at least two sensors, which are connected by electrical conductors to a source of electrical voltage (2) and to an evaluation unit (3), are mounted in different positions in the vehicle. To simplify the installation of the device, the sensors (1) are attached a certain distance apart to a common ribbon cable (4) with parallel electrical conductors, which cable has at least one conductor which can be connected to the voltage source (2) to supply power to the sensors (1) and several signal conductors, which can be connected to the evaluation unit (3) and possibly also to the voltage source (2), the number of which corresponds to the number of sensors to be connected. All of the sensors (1) are connected to the power-supply conductor, and each one is connected individually to one of the signal conductors.
