Abstract: A data system of a towing vehicle and/or trailer vehicle includes a control device, a sensor system configured to record and process sensor data, and a BUS system configured to transfer the sensor data between the control device and the sensor system. The BUS system has a first BUS device in the form of a CAN BUS and a second BUS device in the form of an ETHERNET BUS, and the BUS system further has a first interface configured to transfer the sensor data to a second interface of a second BUS system of a second data system of a second towing vehicle and/or trailer vehicle. The data system additionally includes an intelligent switch, coupled to the control device and/or to the first interface, the intelligent switch being configured to couple the first towing vehicle and/or trailer vehicle to the second towing vehicle and/or trailer vehicle in a coordinated manner.

Abstract: To effect redundant signal processing of a safety-relevant application, such as for a safety control unit of a motor vehicle, at least two redundant signals are fed from at least one sensor to an electronic circuit assembly as input signals for processing. At least one input signal is converted into a different test signal. In the electronic circuit assembly, the input signals are fed to a first peripheral module of a microcontroller, and the test signal is fed to an additional peripheral module. The sensor information of the input signals and of the test signal are thus redundantly processed independently of each other in a respective peripheral module of the microcontroller.

Abstract: A control unit of a vehicle brake system has a receive circuit for tapping and processing a digital signal provided by an active speed sensor for speed measurement on a vehicle wheel. The signal includes information concerning the speed of a pole wheel, which is arranged in front of the sensor, spaced therefrom by an air gap, and which rotates along with the wheel. The signal also includes an actual air gap value digitized in stages and comprising several bits. The control unit also has a comparator circuit for comparing the actual air gap value to a reference air gap value and for determining whether the actual air gap value exceeds the reference value by more than a defined tolerance value. An information circuit of the control circuit generates early warning information when the comparator circuit determines that the actual air gap value exceeds the reference value by more than the tolerance value.

Abstract: The invention relates to a method for the redundant signal processing of a safety-relevant application, in particular of a safety control unit of a motor vehicle, wherein at least two redundant signals are fed from at least one sensor (4) to an electronic circuit assembly (2) as input signals (6) for processing of the sensor information. At least one input signal (6) is converted into a different test signal (16). In the electronic circuit assembly (2), the one or more input signals (6) are fed to a first peripheral module (12) of a microcontroller (10), and the test signal (16) is fed to an additional peripheral module (18) of the microcontroller (10). The sensor information of the input signals (6) and of the test signal (16) are thus redundantly processed independently of each other in a respective peripheral module (12, 18) of the microcontroller (10).

Abstract: Method for bonding a layer of thermoplastic polymer to the surface of an elastomer. A foamed elastomer having, preferably, an open-pore surface is used. The thermoplastic layer is pressed against this surface while it is heated by heat radiation, in particular laser light. The thermoplastic layer is transparent to this radiation, whereas it is absorbed by the surface of the elastomer.
