A method for evaluating sensor data. The sensor data are ascertained by scanning a surrounding area, using at least one sensor. On the basis of the sensor data, object detection is carried out for determining objects from the sensor data. Object filtering is carried out. Surface characteristics of at least one object are identified, and/or the surface characteristics of at least one object are ascertained with the aid of access to a database. A control unit is also described.

A vehicle network for a vehicle, which is couplable to a further vehicle to form a vehicle combination, the vehicle network comprising an inter-vehicle transceiver configured to communicate with a corresponding inter-vehicle transceiver of a vehicle network in said further vehicle, the intervehicle transceiver further configured to perform beam adaptation guided by: (a) radio measurements aiming to localize the corresponding inter-vehicle transceiver, or (b) an articulation angle of the vehicle combination.

A non-line-of-sight radar apparatus includes a first radar receiver to convert a first frequency radar signal received through a non-line-of-sight into a digital signal and to output a first path signal; a first signal processor to receive a second path signal from a direct-line-of-sight detection apparatus detecting a direct-line-of-sight, to cancel a direct-line-of-sight signal irrelevant to the non-line-of-sight included in the first path signal using the second path signal, and to extract a non-line-of-sight signal; and a first signal detector to detect an object on a non-line-of-sight based on the non-line-of-sight signal.

A notification device of an approaching vehicle detects an approach of the other vehicle running a crossroad intersecting a run way of an own vehicle at an anterior intersection and an arrival direction thereof by a radar sensor and notifies a driver thereof. A reflection distance-acquisition part computes a reflection distance Xw according to a difference between absolute values of an X-axis component of a relative position acquired by the radar sensor and an X-axis component of a converted relative position acquired by a relative-position acquisition part of the other vehicle in an X-Y rectangular coordinates with its origin at a location and a Y-axis in a traveling direction of the own vehicle. A notification restriction part forbids a notification of the arrival direction of the other vehicle when the Xw has not fluctuated for a predetermined time or longer.

Methods for determining a location of an object using radio measurement observations in a radio network. An example method comprises the step of obtaining (1610) information comprising (a) a first angle-of-arrival parameter and/or first angle-of-departure parameter corresponding to a non-primary propagation path of a radio signal transmitted between a first wireless device and a second wireless device, and further comprising either or both of (b) a delay measurement or time-of-arrival measurement for the non-primary propagation path: and (c) a second angle-of-arrival parameter and/or second angle-of-departure parameter corresponding to the non-primary propagation path, the second angle-of-arrival parameter and second angle-of-departure parameter corresponding to a different end of the non-primary propagation path to the first angle-of-arrival parameter and angle-of-departure parameter. The method further comprises estimating (1620) a location for an object other than the first and second wireless devices, based on the obtained information.

This document describes techniques and systems to enable a radar system to jointly detect DoA and DoD angles in multipath scenarios. In some examples, an automotive radar system includes one or more processors. The processors obtain electromagnetic (EM) energy reflected by objects and generate, based on the reflected EM energy, a two-dimensional (2D) data matrix. The 2D data matrix has a number of rows corresponding to the number of antenna elements in a transmitter array and a number of columns corresponding to the number of antenna elements in a receiver array. Using the 2D data matrix, the processors can determine DoA estimates and DoD estimates in both monostatic and bistatic reflection scenarios. By comparing the DoA estimates to the DoD estimates, the processors determine angles associated with the objects with improved angular resolution and reduced cost.

Disclosed are methods and systems for environment detection in which a first vehicle detects its vehicle environment with at least one sensor, wherein the first vehicle transmits sensor data of the sensor pertaining to its vehicle environment to an off-board server device; at least one second vehicle with at least one sensor transmits sensor data of the sensor pertaining to its vehicle environment to the off-board server device; the off-board server device merges the transmitted sensor data of the vehicles and generates an environmental model of the vehicle environment of the first vehicle on the basis thereof; the environmental model that is generated is subsequently transmitted by the off-board server device to the first vehicle.

Apparatuses, methods, and systems are disclosed for configuration corresponding to a reconfigurable intelligent surface controller. One method includes providing a capability report to a location management function. The capability report corresponds to reconfigurable intelligent surfaces used for positioning. The method includes transmitting control information to a reconfigurable intelligent surface controller for reflecting a positioning reference signal received from a transmitting device and directed to a receiving device.

The method includes transmitting, to the receiving device, information indicating to report measurements corresponding to multi-port positioning reference signals reflected from multiple reconfigurable intelligent surfaces.

A centralized occupancy detection system enables monitoring of multiple seats, or more generally, multiple stations, with a single sensor. One illustrative vehicle includes: one or more stations each configured to accommodate an occupant of the vehicle, a radar-reflective surface, and a radar transceiver configured to use the radar-reflective surface to detect an occupant of at least one of the stations. Another illustrative vehicle includes: multiple stations to each accommodate an occupant of the vehicle, and a radar transceiver configured to examine each of the multiple stations to determine whether that station has an occupant.

A control system is suitable for use in a motor vehicle and is configured and intended for detecting a position and/or a speed of an object in the surroundings of the host motor vehicle according to determined objects and/or according to driving-related information concerning other motor vehicles, based on surroundings data from at least one surroundings sensor situated on the host motor vehicle and provided to the control system. Based on these surroundings data, an object in the surroundings of the host motor vehicle is detected, and a virtual position and/or a virtual speed are/is associated with this object. The virtual position and/or speed associated with the object are/is adapted based on the driving-related information concerning another motor vehicle and/or based on driving-related information concerning the host motor vehicle, in order to determine an instantaneous position and/or an instantaneous speed of the object.
