摘要： In traffic, vehicle safety generally depends on the relative separation between two vehicles, and not at all on their absolute geographical positions. Therefore, methods are disclosed for determining the relative separation differentially. Two vehicles simultaneously acquire the same satellite signals, reduce the signals to data, and then transmit the data, preferably with fast 5G or 6G, to one of the vehicles or to a roadside access point. A computer then analyzes the data based on differences between the two sets of signals, thereby determining the separation distance and angle between the two vehicles. Other vehicles within range can do the same. The relative locations of all the participating vehicles can then be broadcast, in the form of a table or a map, to all the vehicles in proximity. Improved position measurements can enable collision avoidance and harm minimization in traffic.

摘要： Systems, methods, and autonomous vehicles for detecting road marking points from LiDAR data may obtain a LiDAR dataset generated by a LiDAR system; process, for each laser emitter of the LiDAR system, a point cloud associated with that laser emitter by: determining, for each point in the point cloud, based on a gradient of intensity at that point, whether that point corresponds to a gradient edge point; and determining, based on intensities of points in an interior segment of points between at least one candidate pair of gradient edge points and intensities of points in exterior segments of points outside the at least one candidate pair of gradient edge points, whether that candidate pair of gradient edge points corresponds to a road marking edge; and aggregate, from the processing of the plurality of point clouds, candidate pairs of gradient edge points determined to correspond to road marking edges.

摘要： Vehicles in traffic are expected to communicate wirelessly, to avoid collisions and facilitate the flow of traffic. Unfortunately, in 5G and 6G, the process of finding a wireless address of a specific vehicle is slow and difficult. Disclosed is a “connectivity matrix”, an emblem that vehicles can display, showing a pattern of black and white squares that forms a unique code. Another vehicle can autonomously read the code and look up the wireless address in a tabulation. The tabulation relates each code to the relevant wireless address, and optionally other information about the vehicle. The two vehicles can then transfer messages, including emergency messages, without delay. At freeway speeds, this can save lives. A central entity maintains the tabulation, ensuring that each wireless address is associated with a unique connectivity matrix code. Roadside companies and access points can also display a connectivity matrix, promote communication with prospective customers.

摘要： Mobile wireless terminals, such as vehicles in traffic, can determine the relative positions of other vehicles with improved precision by arranging to acquire GNSS (global navigational satellite system) signals simultaneously, and then analyzing the various data sets differentially. Simultaneous acquisition can cancel many important errors such as motional errors of the vehicles, atmospheric distortions, and satellite timebase errors. Differential analysis to determine the relative positions of vehicles (as opposed to their overall geographical coordinates) can reduce errors related to satellite ephemeris and velocity, as well as roundoff errors. Localization with a precision of less than 1 meter can greatly improve collision avoidance while discriminating near-miss scenarios from imminent collisions, according to some embodiments. Messaging examples, in 5G and 6G, to manage the simultaneous acquisition and differential analysis, are provided in examples. Many other aspects are disclosed.

摘要： A system includes a processor configured to determine a navigation instruction execution location within a predefined distance from a vehicle location. The processor is also configured to communicate with a wireless transceiver to receive information identifying an intervening turn-option location, between the execution location and vehicle location. The processor is further configured to determine a distance between the vehicle location and turn-option location and display the determined distance on a navigation display, until the vehicle passes the turn-option location.

摘要： Autonomous vehicles are required to communicate with each other in 5G or 6G, to avoid hazards, mitigate collisions, and facilitate the flow of traffic. However, for cooperative action, each vehicle must determine the wireless address and position of other vehicles in proximity, so that they can communicate directly with each other. It is not sufficient to know the wireless address alone; the wireless address must be associated with an actual vehicle in view. Methods disclosed herein enable vehicles to simultaneously acquire 360-degree images of other vehicles in traffic, and transmit those images wirelessly along with their wireless addresses. The various images are then “fused” by identifying objects that are viewed from at least two directions, and calculating their positions by triangulation. The resulting traffic map, or a listing of the vehicle positions, is then broadcast along with the wireless addresses of the vehicles The vehicles can then determine which wireless address belongs to which of the vehicles in proximity, and can thereby cooperate with each other to avoid accidents and facilitate the flow of traffic.

摘要： Park monitoring methods, park monitoring systems, and computer-readable storage media are provided. A method includes: determining a first path from a current position of a first object to a first position; generating a 3D virtual image of a surrounding environment when the first object is moving along the first path based on a perspective of the first object; and when the first object is located at the first position, displaying a real image of the first position.
