Patent number: 11921188Abstract: A method for determining direction information for at least one target object in a radar system for a vehicle. The first detection information is provided by at least two receive antennas of the radar system, wherein the first detection information is specific for a first radar signal transmitted by a first transmit antenna of the radar system. The second detection information is provided by the at least two receive antennas of the radar system, wherein the second detection information is specific for a second radar signal transmitted by a second transmit antenna of the radar system. A first angle determination and a second angle determination are performed. At least one comparison of the first angle information with the second angle information is performed in order to detect an ambiguity in the first angle determination for the determination of the direction information.Type: GrantFiled: March 17, 2021Date of Patent: March 5, 2024Assignee: Hella GmbH & Co.

Publication number: 20190004146Abstract: A radar sensor with a signal generation unit that generates a sequence of output signals for the generation of a radiated radar signal. The radar sensor has a signal receiving unit for the reception and for the processing of reflected radar signals as received signals, which are further processed for the analysis of the received signals. A sequence of voltage signals rising from a starting frequency are generated as output signal. The respective received signals are analyzed by means of Fourier analysis, and the output signals have a modulated starting frequency.Type: ApplicationFiled: January 3, 2017Publication date: January 3, 2019Inventor: Andreas von Rhein

Patent number: 9835713Abstract: A device, particularly a radar sensor, has a voltage-controlled oscillator for generating a high-frequency signal which has an actual frequency, a voltage adjusting device to control the oscillator, and a calibration device operable for adjusting a voltage value which is assigned to a value of a target frequency. The calibration device is operable for finding a difference between a frequency and the target frequency corresponding to the voltage set at the oscillator. The calibration device is also operable for generating a low-frequency signal from the high-frequency signal, determining the oscillation period of the low-frequency signal, calculating an auxiliary frequency from the oscillation period of the low-frequency signal, wherein the auxiliary frequency corresponds to the actual frequency of the high-frequency signal, and for adjusting the voltage value assigned to the target frequency according to the frequency difference between the auxiliary frequency and the target frequency.Type: GrantFiled: December 5, 2011Date of Patent: December 5, 2017Assignee: Hella KGaA Hueck & Co.Inventor: Andreas von Rhein

Patent number: 9678203Abstract: A method for determining at least one parameter for the purpose of correlating two objects (10, 20), particularly the distance (r) and/or the relative speed (v) of the two objects (10, 20). A plurality of transmission pulse sequences following one after the after, each with at least one transmission pulse of an electromagnetic signal, forms a series of transmission pulse sequences. The duration of transmission of the individual transmission pulses is varied from transmission pulse sequence to transmission pulse sequence in order to reduce the susceptibility to interference in the determination of the at least one parameter.Type: GrantFiled: November 21, 2012Date of Patent: June 13, 2017Assignee: Hella KGaA Hueck & Co.Inventor: Andreas von Rhein

Device with a voltage-controlled oscillator and a circuit arrangement for controlling the oscillator
Patent number: 9594157Abstract: The present invention relates to a radar sensor. The radar sensor includes a voltage-controlled oscillator for generating a high-frequency signal with an actual frequency. The radar sensor also includes a circuit arrangement to control the oscillator, more specifically for adjusting a voltage to control the oscillator, with each value of a target frequency being allocated to a voltage value of the voltage intended to control the oscillator. The circuit arrangement to control the oscillator includes a signal generator with at least two signals that can be generated by the signal generator. The two signals may be two digital signals, two pulse-width modulated signals, or one digital and one pulse-width modulated signal. The signal generator also may include a first output, at which a digital signal can be provided or two digital signals can be provided and/or a second output at which a pulse-width modulated signal can be provided.Type: GrantFiled: January 18, 2013Date of Patent: March 14, 2017Assignee: HELLA KGAA HUECK & CO.Inventor: Andreas von Rhein -
