摘要： A method of detecting a hand positioning on a steering wheel (38) by operating a sensing system (10) including at least one electrically conducting signal line (12) that is arrangeable on a rim of the steering wheel (38) with a priori knowledge about a relation between a distance of any portion of the at least one signal line (12) from a reference point (30) and information on a position on the rim (40), and which comprises an electric impedance change (28) of predefined magnitude that is permanently arranged at a predefined position along the at least one signal line, a signal voltage source (26), and a control and evaluation unit (28). From a received measurement signal traveling along the signal line (12) and having been reflected by the at least one electric impedance change (28) and by another portion or other portions of the signal line (12), a reference travel time is determined. Based on the determined reference travel time and the a priori known relation, a position or positions on the rim (46) of the other portion or portions of the signal line (12) that has or have at least partially reflected the measurement signal is determined by the control and evaluation unit (28).

摘要： A method of direction of arrival estimation with an automotive spread radar system (10). The automotive spread radar system (10) comprises a plurality of at least two transceiver antenna units (TRx k ), which are configured to work in a MIMO configuration, wherein the transceiver antenna units (TRx k ) are arranged at a priori known positions. The automotive spread radar system is configured to determine, for each transceiver unit antenna unit (TRx k ) of the plurality of transceiver antenna units (TRx k ), a range of a target (28) reflecting radar waves that have been transmitted by at least the specific transceiver antenna unit (TRx k ) by reading out a plurality of range gates (12) assigned to a specific transceiver antenna unit (TRx k ). The method and radar system are capable of estimating a direction of arrival without the need of ensuring a synchronization of antennas on the scale of a radar carrier frequency.

摘要： A method of operating an automotive radar system (10) for avoiding interference by other radar systems is provided. The automotive radar system (10) includes a radar transmitter unit (12) for transmitting radar waveforms ( x Tx , x̃ Tx , ) towards a scene, a radar receiving unit (16) for receiving radar waveforms ( x Rx, x̃ Rx ) that have been reflected by a target (26, 28) in the scene, and an evaluation and control unit (20) for decoding range-Doppler information from the received radar waveforms ( x Rx, x̃ Rx ). The method comprises steps of transmitting (32) a first sequence of radar waveforms ( x Tx ) and a second sequence of radar waveforms ( x̃ Tx , k ) towards the scene that differs from the first transmitted sequence of radar waveforms ( x Tx ) by predetermined phase shifts ( φ k ) such that each radar waveform ( x̃ Tx , k ) of the second sequence has a different predetermined phase shift ( φ k ). First range-Doppler information and second range-Doppler information are decoded (36). Deviations of the second range-Doppler information from the first range-Doppler information are compared (44) to at least one predetermined deviation value. Based on the results of the comparing, a potential interference condition is identified (46).

摘要： A method of recognizing a hand gesture established by a sequence of hand touch positionings on an object, particularly on a steering wheel (38) by operating a sensing system (10) comprising at least one electrically conducting signal line (12), which is arranged to extend along a part of a surface of the object with a priori knowledge about a relation between a distance of any portion of the at least one signal line (12) from a reference point (44) and information on a position on the object, a signal voltage source (26) that is operatively connectable to each signal line (12), and a control and evaluation unit (28) that is operatively connectable to each signal line (12). The method comprises at least steps of: providing (50) to a signal line (12) a time-dependent measurement signal; receiving (52) the measurement signal after being at least partially reflected by at least one portion of the signal line (12); determining (54) positions on the object of the portions of the signal line (12) that have reflected the measurement signal; comparing an obtained plurality of stored successively determined positions on the object with at least one predefined pattern of successive positions to derive (60) a measure of similarity; and providing (64) an output signal that is indicative of the predefined pattern of successive positions if the derived measure of similarity is lower than a predefined threshold value (Thr).
