This document describes techniques and systems for improving accuracy of predictions on radar data using vehicle-to-vehicle (V2V) technology. V2V communications data and the matching sensor data related to one or more vehicles in the vicinity of a host vehicle are collected. The V2V data is used as label data and the radar data is used as the input data for training the model. The training may either occur onboard the host vehicle or remotely. Further, multiple host vehicles may contribute data to train the model. Once the model has been updated with the included training, the updated model is deployed to the sensor tracking system of the host vehicle. By using the dataset that includes the V2V communications data and the matching sensor data, the updated model may accurately track other vehicles and enable the host vehicle to utilize advanced driver-assistance systems safely and reliably.

A system includes a tracking system, a controller-circuit, and a device. The tracking system is configured to detect and track an object, and includes one or more of a computer vision system, a radar system, and a LIDAR system. The controller-circuit is disposed in a host vehicle, and is configured to receive detection signals from the tracking system, process the detection signals, determine, whether an object is detected based on the processed detecting signals, and in accordance with a determination that an object is detected, output command signals. The device is adapted to be mounted to the host vehicle, and is configured to receive the command signals and thereby provide a dynamic visual indication adapted to change in accordance with orientation changes between the host vehicle and the object. The dynamic visual indication is viewable from outside of the host vehicle.

An absorber device for electromagnetic sensor systems has at least one aperture. Each aperture is able to be opened and closed by an aperture closure. The absorber device is designed in such a way that when the aperture is open, electromagnetic waves incoming through the aperture do not then leave the absorber device, and when the aperture is closed, electromagnetic waves impinging on the aperture are reflected.

The invention describes a method for reducing interference effects in a radar system, which has at least two transceiver units (S1, S2), which are in particular spatially separated from one another, wherein the method comprises the following steps: —a transmission step (VS1), in which a first transmission signal (sigTX1) of the first transceiver unit (S1) is sent and received to and by a second transceiver unit (S2) and a second transmission signal (sigTX2) of the second transceiver unit (S2) is sent and received to and by the first transceiver unit (S1) via a radio channel (T), wherein the transmission signals (sigTX1, sigTX2) are modulated according to an orthogonal frequency multiplex method; and—a pre-correction step (VS2), in which correction values (γ1, γn, γ2) are determined from the received transmission signals (sigTX1, sigTX2) and in particular are exchanged between the transceiver stations (S1, S2), wherein the received transmission signals (sigRX1, sigRX2) are postprocessed on the basis of the correction values (γ1, γn, γ2), so that influences of interference variables, in particular of phase noise and/or a time offset and/or unknown initial phase positions, are reduced.

A communication device includes a target locating unit configured to locate a position of a target having a risk of approaching a moving body. The communication device includes a transmission unit configured to transmit request information including positional information of an external terminal, for which the positional information is requested, based on the position of the target located by the target locating unit. The communication device includes a reception unit configured to receive response information with respect to the request information. The transmission unit is configured to transmit warning information based on the positional information of the external terminal included in the response information.

The present disclosure provides a system, a method and an apparatus for position-based parking of a vehicle, capable of solving the problem in the related art that an unmanned vehicle cannot be parked at a specified position accurately in an environment with a weak GPS signal. The method includes, during position-based parking of a vehicle at a predetermined position: receiving, by a communication device of the vehicle, posture data from a roadside device located within a predetermined range from the predetermined position; deciding, by a vehicle-mounted processing device of the vehicle, whether received posture data satisfies a predetermined positioning rule; determining posture adjustment data for the vehicle when the received posture data does not satisfy the predetermined positioning rule; and controlling the vehicle to perform a posture adjustment operation based on the posture adjustment data.

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.

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. In some aspects, the apparatus may be a user equipment (UE) or a component thereof; however, in some other aspects, the apparatus may be a base station or a component thereof. The apparatus may be configured as a wireless node that configures an intermediary apparatus to reflect signals for the wireless node and another wireless node. The apparatus may be further configured to communicate a set of sensing signals with the other wireless node using the intermediary apparatus. The apparatus may be further configured to sense an object based on a set of measurements associated with the set of sensing signals.

Example embodiments relate to methods and systems for implementing radar electronic support measure operations. A vehicle's processing unit may receive information relating to electromagnetic energy radiating in an environment of the vehicle that is detected using a vehicle radar system. The electromagnetic energy originated from one or more external emitters, such as radar signals transmitted by other vehicles. The processing unit may determine a spectrum occupancy representation that indicates spectral regions occupied by the electromagnetic energy and subsequently adjust operation of the vehicle radar system based on the spectrum occupancy representation to reduce or mitigate interference with the external emitters in the vehicle's environment. In some examples, the vehicle radar system may be switched to a passive receive-only mode to measure the electromagnetic energy radiating in the environment from other emitters.

Systems and methods for mapping location and characteristics about traffic participants are described. The systems and methods advantageously use correlative receivers for observing wireless emissions from or reflected by a plurality of traffic participants to allow for tracking geolocation and velocimetry information in real-time. The real-time geolocation and velocimetry information can be useful in autonomous vehicle navigation applications and useful for reducing computational burdens associated with tracking locations of many multiple traffic participants using direct sensor measurements, for example.
