Abstract: A multi-lane scenario driving support is provided for an ego vehicle in a traffic situation. Traffic surroundings are measured by an environment sensor system. The traffic surroundings include data about traffic and free space within an ego lane of the ego vehicle and an adjacent lane, and data about front proximity area and rear proximity area of the ego vehicle. A decision device evaluates the measured traffic surroundings and decides a driving operation to be executed by the ego vehicle based on at least one strategy. In the decision device, a cost function is used for choosing one of at least six strategies. The cost function is based on at least a core priority to avoid collision of the ego vehicle and not cause collision of the ego vehicle with a third party vehicle.

Abstract: The invention relates to a method for ascertaining a yaw-rate offset value (ωoffset) which represents the offset of yaw-rate measurement values of a yaw-rate sensor (2) of a motor vehicle (1). The method has the following steps: receiving (100) a plurality of yaw-rate measurement values (ω1, . . . , ωx) from the yaw-rate sensor (2) over time (t), said measurement values constituting a yaw-rate measurement signal (Sω); checking (200) whether the motor vehicle (1) is at a standstill; and if so, ascertaining (500) the yaw-rate offset value (ωoffset) on the basis of the yaw-rate measurement signal (Sω). The method is characterized by the steps of ascertaining (300) yaw-rate measurement values (Gst) which form a slope (St) in the yaw-rate measurement signal (Sω); and disregarding (400) the ascertained yaw-rate measurement values (Gst) which form a slope (St) in order to ascertain (500) the yaw-rate offset value (ωoffset).

Abstract: A method for controlling a drive apparatus (18) of a micro-oscillation mirror (16), a control device (28) and a deflector mirror apparatus (14) are described. In the method, at least one actuation signal (20) is generated, and the drive apparatus (18) is actuated therewith in such a way that it drives the micro-oscillation mirror (16) in an oscillating fashion, At least one position signal (26) which characterizes the deflection (22) of the micro-oscillation mirror (16) is sensed. The at least one actuation signal (20) is closed-loop controlled on the basis of the at least one position signal (26) in such a way that the micro-oscillation mirror (16) is driven at its resonant frequency, The amplitude of the at least one position signal (26) is continuously compared with at least one threshold value (38a, 38b, 38c). At least one time interval (42a, 42b, 42c) between at least two passes of the at least one position signal (26) through at least one threshold value (38a, 38b, 38c) is determined. The at least one actuation signal (20) is closed-loop controlled on the basis of the at least one time interval (42a, 42b, 42c).

Abstract: A method for determining at least one object information item of at least one target object (18) which is sensed with a radar system (12) of a vehicle (10), a radar system (12) and a driver assistance system (12) are described. Transmission signals (32a, 32b, 32c) are transmitted into a monitoring range (14) of the radar system (12) with three transmitters (Tx1, Tx2, Tx3). Echoes, which are reflected at the at least one target object (18), of the transmission signals (32a, 32b, 32c) are received as received signals (34a, 34b, 32c) with at least two receivers (RxA, RxB, RxC, RxD). The received signals (34a, 34b, 34c) are subjected to at least one multi-dimensional discrete Fourier transformation.

Abstract: A method for verifying the functionality of a laser scanner includes a housing with a light-permeable window, a transmission unit inside the housing, a deflection unit, and a detector unit inside the housing. At least one test signal is transmitted by the transmission unit during a test phase. The deflection unit is oriented so that the at least one test signal is not directed to the window. Components of the at least one test signal are detected by the detector unit, and based on this detection, at least two detector signals are generated. A pulse width is ascertained for each of the detector signals by a computing unit, and a ratio of the pulse width of a first detector signal to the pulse width of a second detector signal is ascertained. The operability of the transmitter unit and/or the detector unit is verified on the basis of said ratio.
