Abstract: The present invention relates to a method for calibration of a radar system (14) of a vehicle (10) for monitoring an environment of the vehicle (10). During a movement of the vehicle (10) with the radar system (14) at least one radar signal (22) is transmitted into a monitoring area (18). With the radar system (14) at least one echo signal (26) of at least one radar signal (22) is received, which is reflected from at least one target (24). At least one phase-based target angle (ΦS) is determined from at least one phase difference of the at least one received echo signal (26), which is received with different antennas of the radar system (14), wherein the phase-based target angle (ΦS) characterizes the direction of the at least one detected target (24) with respect to a radar reference system (28S) of the radar system (14). At least one Doppler-based target angle (ΦH) is determined from at least one Doppler shift of the at least one received echo signal (26) and a vehicle velocity (vH) of the vehicle (10), wherein the Doppler-based target angle (ΦH) characterizes the direction of the at least one detected target (24) with respect to a nominal reference system (28H) defining the calibration situation with the nominal mounting of the radar system (14) at the vehicle (10). At least one angle correction value (ΔΦ) is determined from a difference of at least one phase-based target angle (ΦS) and at least one Doppler-based target angle (ΦH). The at least one angle correction value (ΔΦ) is stored with at least one of the corresponding target angles (ΦS) in a correction lookup table for the purpose of correcting phase-based target angles (ΦS) at least from subsequent measurements with the radar system (14) to corrected target angles (Φcorr).

Abstract: An automated steering device is provided usable in conjunction with power equipment machines. By way of example, the automated steering device can provide user-assisted steering for a power equipment machine to maintain tight parallel paths. The user-assisted steering can be defined relative to an initial vector traversed through user directed operation of the power equipment machine, independent of or at least in part independent of a predefined area of operation for the power equipment machine. Position location data refined by local terrestrial positioning system correction devices, or onboard rotational correction devices can be provided to obtain high positioning accuracy, and minimal path deviation. As a result, highly accurate pathing can be provided by way of the disclosed automated steering devices.

Abstract: Systems, apparatuses, and methods to response to distinguish a ghost target from an actual target based on radar signals and ranges determined from the radar signals. In particular, the disclosure provides an intrusion detection system receiving ranges and velocities for targets detected based on radar signals, determining a potential ghost target from the received velocities and confirming the potential ghost target based on estimated ranges and perturbations of the vehicle speed.

Abstract: Die Erfindung betrifft ein Verfahren zur Überprüfung eines Radarsensors (110) eines Fahrzeuges (1), wobei die nachfolgenden Schritte während eines Betriebs des Radarsensors (110) wiederholt durchgeführt werden: - Erfassen einer ersten Erfassungsinformation (B1) einer ersten Empfangsantenne (111) des Radarsensors (110), um durch die erste Erfassungsinformation (B1) zumindest eine Entfernungsinformation (e) zu erhalten, - Erfassen wenigstens einer weiteren Erfassungsinformation (B2) wenigstens einer weiteren Empfangsantenne (112) des Radarsensors (110), um zusätzlich zur Entfernungsinformation (e) eine Richtungsinformation (f) zu erhalten, - Durchführen wenigstens einer Verarbeitung (210) der Erfassungsinformationen (B1, B2), um jeweils eine verarbeitete Erfassungsinformation (B1', B2') zu erhalten, um aus der Richtungsinformation (f) eine Vergleichsinformation (x') zu erhalten, - Bestimmen einer Abweichung zwischen der Vergleichsinformation (x') und einer Referenzinformation (g), um für die Überprüfung des Radarsensors (110) anhand der Abweichung eine Funktionsbeeinträchtigung des Radarsensors (110) zu detektieren, - Aktualisieren der Referenzinformation (g) anhand der Richtungsinformation (f), insbesondere anhand der Vergleichsinformation (x').
