DUPLICATED WIRELESS TRANSCEIVERS ASSOCIATED WITH A VEHICLE TO RECEIVE AND SEND SENSITIVE INFORMATION
A vehicle is provided that comprises two or more radio frequency (RF) antennas and two or more RF transceivers to communicate wirelessly sensitive information associated with a user of the vehicle (the two or more RF antennas being at different physical locations on an exterior of the vehicle). The vehicle determines which one of the two or more RF antennas is receiving a strongest signal from a common signal source, selects a first RF transceiver associated with the RF antenna with the strongest signal to send the sensitive information associated with the user to the common signal source, and sends the sensitive information associated with the user to the first RF transceiver for transmission to the common signal source.
Radar device for vehicle, controlling method of radar device and radar system for vehicle
The present disclosure relates to a vehicle radar device, a controlling method thereof, and radar system. A radar device according to an embodiment includes a transceiver being controlled to transmit the transmission signal in an operating frequency band according to a selection mode among a plurality of frequency band modes and to receive the reception signal through the receiving antenna, and a mode selector dynamically determining one of the plurality of frequency band modes as the selection mode based on at least one of a target distance to the target and a maximum detection distance for each frequency band. According to embodiments of the present disclosure, the distance resolution of the radar can be optimized by dynamically varying the frequency bandwidth linked with the maximum detection distance according to a target distance under specific driving conditions.
Location data correction service for connected vehicles
The disclosure includes embodiments for a location data correction service for connected vehicles. A method includes receiving, by an operation center via a serverless ad-hoc vehicular network, a first wireless message that includes legacy location data that describes a geographic location of a legacy vehicle. The method includes causing a rich sensor set included in the operation center to record sensor data describing the geographic locations of objects in a roadway environment. The method includes determining correction data that describes a variance between the geographic location of the legacy vehicle as described by the sensor data and the legacy location data. The method includes transmitting a second wireless message to the legacy vehicle, wherein the second wireless message includes the correction data so that the legacy vehicle receives a benefit by correcting the legacy location data to minimize the variance.
Autonomy first route optimization for autonomous vehicles
Embodiments herein can determine an optimal route for an autonomous electric vehicle. The system may score viable routes between the start and end locations of a trip using a numeric or other scale that denotes how viable the route is for autonomy. The score is adjusted using a variety of factors where a learning process leverages both offline and online data. The scored routes are not based simply on the shortest distance between the start and end points but determine the best route based on the driving context for the vehicle and the user.
TERRAIN-SENSITIVE ROUTE PLANNING
Route planning is provided to a vehicle (or vehicle driver) based at least in part on the type of vehicle and the terrain conditions between the originating location and destination. The vehicle may employ a terrain monitoring system including a surface-penetrating radar (SPR) system for obtaining SPR signals as the vehicle travels along a route; the obtained SPR signals may be used for navigation against reference images associated with the route. In some embodiments, a navigation server bases route selection in part on the terrain associated with various routes and characteristics of the vehicle.
METHOD AND APPARATUS FOR POSITIONING USING BACKSCATTER TAG
Provided herein is a method of performing, by a first apparatus, wireless communication. The method may include the steps of transmitting a first signal to a second apparatus through at least one antenna; receiving a second signal from the second apparatus through each of the at least one antenna; obtaining the sequence and a distance between the first apparatus and the second apparatus based on the second signal; obtaining information related to the second apparatus based on the sequence; and obtaining first location information related to the first apparatus, based on the distance and the information.
SYSTEMS AND METHODS FOR ROUTE SYNCHRONIZATION FOR ROBOTIC DEVICES
Systems and methods for route synchronization between two or more robots to allow for a single training run of a route to effectively train multiple robots to follow the route.
Systems and methods for estimating vehicle speed based on radar
Systems, methods, and other embodiments relate to determining the speed of a vehicle. In one embodiment, a method includes receiving a first frame of data generated by a first sensor of a vehicle, the first frame of data including a first set of angular positions associated with a first set of objects in the environment. The method includes receiving a second frame of data generated by a second sensor of the vehicle, the second frame of data including a second set of angular positions associated with a second set of objects in the environment. The method includes generating a speed estimate for the vehicle in relation to the first set of objects and the second set of objects based at least in part on the first set of angular positions of the first frame of data and the second set of angular positions of the second frame of data.
Secure vehicle communications architecture for improved blind spot and driving distance detection
Disclosed are techniques for improving an advanced driver-assistance system (ADAS) using a secure channel area. In one embodiment, a method is disclosed comprising establishing a secure channel area extending from at least one side of a first vehicle; detecting a presence of a second vehicle in the secure channel area; establishing a secure connection with the second vehicle upon detecting the presence; exchanging messages between the first vehicle and the second vehicle, the messages including a position and speed of a sending vehicle; taking control of a position and speed of the first vehicle based on the contents of the messages; and releasing control of the position and speed of the first vehicle upon detecting that the secure connection was released.
Frequency division multiple access in vehicle radar system
A method of implementing frequency division multiple access (FDMA) in a radar system of a vehicle includes transmitting a chirp signal from each of a plurality of transmit elements of the radar system simultaneously. The chirp signal transmitted by each of the plurality of transmit elements increases or decreases linearly in frequency over a frequency range over a duration of time and the frequency range of the chirp signal transmitted by adjacent ones of the plurality of transmit elements partially overlapping. The method also includes processing a reflection received based on reflection of the chirp signal transmitted by the plurality of transmit elements by one or more objects and controlling an operation of the vehicle based on locating the one or more objects.
