    摘要: A method and system for operating a LiDAR system for an environment detection in a field of view (FOV) of the system, wherein the following steps are performed: detection of at least one temperature measurement, which differs from a loading temperature in at least one light source of the system, estimation of the loading temperature based on the temperature measurement using an evaluation function, specification of an operating limit, which is specific for the maximum thermal load capacity of the light source, provision of a preset for at least one region of interest (ROI) in the field of view (FOV), adjustment of an operation of the system, and based on the preset for the region of interest (ROI) and the estimated loading temperature and the operating limit.

    摘要: The invention relates to a method for operating an optoelectronic detection device (12) for monitoring at least one monitoring region (14) with optical monitoring signals (34), and to an optoelectronic detection device (12). In the method, at least one first receive start signal (58a) is sent to at least one first receiver (24a), and at least one second receive start signal (58b) is sent to at least one second receiver (24b). In response to the at least one first receive start signal (58a), a receive process which is carried out with the at least one first receiver (24a) is started and at least one first trigger signal (44a) is generated with the at least one first receiver (24a). In response to the at least one second receive start signal (58b), a receive process which is carried out with the at least one second receiver (24b) is started and at least one second trigger signal (44b) is generated with the at least one second receiver (24b). From the at least one first trigger signal (44a) and the at least one second trigger signal (44b), a transmission trigger signal (64) is determined, which corresponds to the later of the at least two trigger signals (44a, 44b) at least in terms of its trigger function. In response to the transmission trigger signal (64), at least one optical monitoring signal (34) is generated with at least one optical transmitter (22).

    摘要: A doppler lidar system includes an acousto-optic modulator. The acousto-optic modulator frequency shifts light to simulate a Doppler effect of a target without moving the target relative to a transceiver. A detector detects a frequency. One or more processors then calibrate the doppler lidar system based on the detected frequency. The acousto-optic modulator is then decoupled to return the doppler lidar system to a normal operating condition. The acousto-optic modulator is coupled in a transmit path or a receive path of the doppler lidar system.

    摘要: The invention relates to a sensor system (200, 300, 400) for a motor vehicle, comprising a sensor housing and an active or passive sensor (102) arranged therein and held on a movable sensor holder (201, 401), having a sensor technology based on radiation detection and a measurement apparatus assigned to the sensor (102) and a control apparatus, coupled to said measurement apparatus, for the sensor holder (201, 401), wherein the sensor housing has a cover (106, 301) that is signal-transmissive for the sensor (102) on its side located in the detection direction of the sensor (102), and wherein the detection range (108, 109) of the sensor (102) in the region of the signal-transmissive cover (106, 301) has a lower extent than the signal-transmissive cover (106, 301), wherein the sensor system (200, 300, 400) is characterized in that the measurement apparatus is designed such that it is suitable for checking, in the detection range of the sensor (102), whether and in which section the signal-transmissive cover (106, 301) has a region with reduced signal transmissivity (202), wherein the measurement apparatus interacts with the control apparatus in such a way that the control apparatus is able to change the position of the sensor (102) in such a way that the region with reduced signal transmissivity (202) lies outside the detection range (108, 109) of the sensor (102). The invention furthermore relates to a method for operating such a sensor system (200, 300, 400) and to a motor vehicle that is equipped with such a sensor system (200, 300, 400).

    摘要: A camera system for a motor vehicle includes a camera lens, an image sensor configured to receive light from the camera lens and generate image data from the received light, a light emitting device configured to emit light onto a back side of the camera lens, and a control device. The control device may be configured to (a) cause the light emitting device to emit a pulse of light, (b) receive image data from the image sensor for (i) a first time period before the pulse of light is emitted, (ii) a second time period while the pulse of light is being emitted, and (iii) a third time period after the pulse of light has been emitted, (c) compare image data from the second time period with image data from the first and/or third time periods to determine an amount by which a brightness level increases while the pulse of light is being emitted, and (d) based on the amount by which the brightness level increases while the pulse of light is being emitted, determine whether a foreign substance is on a front side of the camera lens.
