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.

The traffic signal apparatus communication system includes a traffic signal apparatus for providing a message to a vehicle. The apparatus includes at least one spatially encoded marker, and the vehicle is configured to receive returns of a radar signal from the spatially-encoded marker. At least one controller of the vehicle is configured to determine the message encoded by the spatially-encoded marker based on the returns and to control the vehicle based on the message. The message may include a value indicating a time to a transition of a new state of the traffic signal apparatus, where the new state includes emission of light from one of a first light source, a second light source, or a third light source of the traffic signal apparatus.

The present disclosure includes systems and methods for controlling the lane positions of a plurality of vehicles to reduce roadway wear. At least one controller is configured to receive information regarding a reference that may indicate a lane boundary. The controller determines a lane position offset from the reference, where the offset may be randomly selected or deterministically determined with an algorithm. The at least one controller is further configured to assign the lane position offset to one vehicle of a group of vehicles so that the assigned offset is different from the lane position offsets of the other vehicles. The assignment of different lane position offsets distributes wear across the lane of the roadway.

Methods and systems are provided for indicating a driving situation including at least one vehicle. The system includes a first processor, a second processor and an external device. A first processor obtains driving information, encodes the driving information and communicates the encoded driving information to the second processor. The second processor receives and decodes the encoded driving information. The second processor further allocates a predefined indication pattern to the decoded driving information, wherein the predefined indication pattern includes a graphical representation of an upcoming driving event involving the vehicle. An external device visualizes a current driving situation including the vehicle together with the predefined indication pattern.

A system and a method manage wireless traffic signals in order to aid autonomous driving systems and humans to quickly and accurately detect traffic signal changes and surrounding traffic. The system includes a plurality of road vehicles. Each road vehicle includes a vehicle receiver, a vehicle controller, and a vehicle output device. The system also includes a plurality of traffic-signal sources and a plurality of signal emitters. Each signal emitter is associated to a corresponding traffic-signal source from the plurality of traffic-signal sources. Each signal emitter processes traffic signals from the corresponding traffic-signal source and sends the processed traffic signals to the vehicle receivers. The vehicle receivers receive signals from the plurality of signal emitters. The vehicle controller processes the signals received by the vehicle receiver. The vehicle output device executes instructions that are extracted from the signals processed by the vehicle controller.

Disclosed are an apparatus for processing a vehicle-to-everything (V2X) message. The apparatus includes a precise road map storage unit configured to store a precise road map and a map message processing unit configured to generate a MAP message for a real-time traffic signal phase information service using the precise road map and divide the MAP message according to the size of the MAP message.

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.

Provided are a driving negotiation method and apparatus for supporting stability against a blind spot, an unexpected situation, etc. and a rapid judgment and response of an autonomous vehicle in various driving environments. The driving negotiation apparatus includes a wireless communication module configured to support vehicle to everything (V2X) communication and at least one processor connected to the wireless communication module. The at least one processor receives a cooperative request message from a first vehicle, broadcasts a cooperative request message and additional information required for a negotiation to surrounding vehicles, receives a cooperative response message from at least one second vehicle among the surrounding vehicles, and transmits a message indicating that the negotiation is possible or impossible to the first vehicle on the basis of the cooperative response message.
