Abstract: A capacitive rotation angle sensor and an associated system with a capacitive rotation angle sensor. The capacitive rotation angle sensor has at least one stator, at least one rotor, and an evaluation unit. The at least one rotor has a main body and multiple rotor vanes extending radially outward from the main body. Multiple first rotor vanes of the multiple rotor vanes are designed differently from multiple second rotor vanes of the multiple rotor vanes. The evaluation unit is designed to detect when the multiple first rotor vanes reach, have reached, or exceed a predetermined rotation angle.

Abstract: A system is provided for detecting obscurants on an outer surface of a lens of a vehicle lamp of a vehicle. The system includes a support, as well as an infrared (IR) light emitter-detector module coupled to the support. The IR light emitter-detector module includes an IR light emitter configured to emit IR light towards an inner surface of the lens, as well as an IR light detector configured to measure an intensity of IR light reflected by the obscurants. A controller is also coupled to the IR light emitter-detector module. The controller is configured to control the IR light emitter-detector module, determine a level of light obstruction based on the measured intensity of reflected IR light, and when the level of light obstruction meets predefined criteria, issue a warning.

Abstract: An improved method for zero-voltage switching (ZVS) of a voltage-fed half-bridge using a variable dead band is provided. The duration of the dead band is determined dynamically and is precisely long enough to ensure the absence of shoot-through events while also minimizing or eliminating switching losses and reverse conduction losses. The method generally includes: (a) calculating the equivalent capacitance as seen by the current source charging the midpoint of the half-bridge; (b) calculating the ZVS charge requirement based on the link voltage and the equivalent capacitance; (c) calculating the charge delivered by the current source over time during a dead band vector, equating the result to the ZVS charge requirement, and solving for the ZVS time requirement at each commutation point over the switching cycle; and (d) updating the dead bands for each commutation of each half-bridge in the switched-mode power converter.

Abstract: A method for communicating information, wherein two sensor devices each have a sensor test value generator with a variable value and with a calculation rule. The variable values and/or the calculation rules are different, and wherein a receiver device has a receiver test value generator with the two variable values and/or with the two calculation rules. The method includes: calculation of the sensor test value, generation of a data packet with the calculated sensor test value, receiving, by the receiver device, of the data packet from the sensor device, selection of the variable value and/or selection of the calculation rule, calculation of a receiver test value, and checking of the received sensor measurement information for a transmission error based on the received sensor test value and the calculated receiver test value.

Abstract: A method for improving an evaluation of object identification of a radar device of a motor vehicle. A first map is generated of the surroundings of said surroundings by a LiDAR scanner. A first object identification is performed on the basis of the generated first map of the surroundings by a first identification apparatus. A ground-truth model is created of the surroundings on the basis of the performed first object identification by the first identification apparatus. A second map is generated of the surroundings of the surroundings by the radar device. A second object identification is repeatedly performed using alternative object identification algorithms on the basis of the generated second map of the surroundings by a second identification apparatus of the radar device. A radar model is created of the surroundings on the basis of the repeatedly performed second object identification by means of the second identification apparatus.

Abstract: An illumination arrangement includes with a control unit, an illumination module connected to the control unit via a bidirectional first channel that features an LED matrix for generating light, and a peripheral module connected to the illumination module via a second channel. The control unit can be used to generate data for controlling the illumination module and for controlling the peripheral module. The data for controlling the illumination module and data for controlling the peripheral module can be transferred to the illumination module via the first channel. The data for controlling the peripheral module can be transferred from the illumination module to the peripheral module via the second channel. The second channel is a bidirectional channel via which data can be transferred from the peripheral module to the illumination module that, after being received by the illumination module, can be transferred to the control unit via the first channel.
