Methods and Systems for Clearing Sensor Occlusions
A method is provided that involves identifying a target region of an environment of an autonomous vehicle to be monitored for presence of moving objects. The method also involves operating a first sensor to obtain a scan of a portion of the environment that includes at least a portion of the target region and an intermediate region between the autonomous vehicle and the target region. The method also involves determining whether a second sensor has a sufficiently clear view of the target region based on at least the scan obtained by the first sensor. The method also involves operating the second sensor to monitor the target region for presence of moving objects based on at least a determination that the second sensor has a sufficiently clear view of the target region. Also provided is an autonomous vehicle configured to perform the method.
SITUATION-DEPENDENT CONTROL OF VEHICLE SENSORS AND/OR COMPONENTS
A method for controlling sensors or components of a vehicle, using a control device. Measurement data of at least one sensor of the vehicle being received and evaluated. A traffic situation, in which the vehicle finds itself, is ascertained by evaluating the measurement data; and the at least one sensor and/or at least one component of the vehicle being activated, deactivated and/or set to a standby mode as a function of the ascertained traffic situation. A control device and a computer program are also described.
Methods And Systems For Measuring Sensor Visibility
Provided are methods for methods and systems for measuring sensor visibility, which can include obtaining sensor data associated with an autonomous vehicle and determining a blockage parameter indicative of a blockage of a sensor based on a comparison of the sensor data with secondary data.

Low-cost device and method for measuring radar transmission and reflectance of coated articles
Low-cost devices for measuring radar transmission and/or reflectance of coated articles are provided. An exemplary low-cost radar transmission and reflection measurement device includes a radar transmitter that emits a radar signal, a radar target to which the radar signal is directed, and a radar receiver that receives the radar signal. Further, the exemplary low-cost device includes a sample holder located between the radar transmitter and the radar target and between the radar target and the radar receiver. The sample holder receives a sample including a coating. The low-cost device also includes a controller connected to the radar transmitter and radar receiver. The controller measures a radar signal loss due to the coating.
RADAR DEVICE
A radar device includes a transmit antenna radiating a modulation signal and a receive antenna receiving reflection waves from the modulation signal. The radar device also includes a mixer mixing the modulation signal and the received signal to output a beat signal, a calculation circuit judging presence or absence of an abnormality by using the beat signal, and a memory storing reference data and a threshold. The reference data indicates a phase component of a set frequency signal from a beat signal without necessarily any abnormality. The set frequency signal is generated from the modulation signal reflected on a surface of a housing located at a set distance from the radar device. The calculation circuit extracts a phase component from the beat signal and supplies information indicating the presence of an abnormality if the difference between the extracted phase component and the reference data is greater than the threshold.
Parking Assistant and Method for Adaptive Parking of a Vehicle to Optimize Overall Sensing Coverage of a Traffic Environment
A method can be used for adaptive parking of a vehicle. A parking area is determined around a programmed destination of the vehicle. The parking area has more than one available parking spot for the vehicle. Parking data is acquired via a wireless communication network. The parking data for each parked vehicle includes a parking position and an individual sensing coverage of an environment sensor system of the respective parked vehicle scanning the traffic environment within the parking area. Available parking spots are ranked based on a calculated overall sensing coverage and a recommended parking spot is determined among the available parking spots based on overall sensing coverage of the traffic environment in the parking area.
Failure detection apparatus, failure detection method, and computer readable medium
A detected data acquisition unit (21) acquires detected data outputted during a past reference period by a sensor (31) mounted on a moving body (100). A peripheral data acquisition unit (22) acquires peripheral data detected by a peripheral body existing on peripheral of the moving body (100). A failure determination unit (23) determines whether or not there is a failure in the sensor (31) based on whether or not the detected data includes detected data that identifies a detected content of which difference from a peripheral content identified from the peripheral data is within a reference scope.
METHOD AND DEVICE FOR RECOGNIZING MISALIGNMENTS OF A STATIONARY SENSOR AND STATIONARY SENSOR
A method for recognizing misalignments of a stationary sensor. A first occupancy map is generated based on first sensor data, which the sensor generates at a first point in time. Based on second sensor data, which the sensor generates at a second point in time, a second occupancy map is generated. A cross-correlation of the first occupancy map and of the second occupancy map is calculated. A misalignment of the sensor is recognized based on the calculated cross-correlation.
