Vehicle communications system with vehicle controller and set of wireless relay devices
Disclosed are techniques for wireless communication. In an aspect, a vehicle communications system of a vehicle comprises a vehicle controller with a wireless communications interface capable of providing wireless coverage in a plurality of vehicle regions, and a set of relay devices that are each communicatively coupled to the vehicle controller and are each capable of providing wireless coverage in at least one of the plurality of vehicle regions.

Precision localization of mobile 5G/6G terminals by coordinated GNSS reception
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.
AUTOMATIC RECOGNITION OF ANOMALOUS SITUATIONS ALONG ROADS TRAVELLED BY MOTOR-VEHICLES FOR INTELLIGENT MOTOR-VEHICLE DRIVING SPEED CONTROL ALONG THE ROADS
System for automatically recognising anomalous situations along roads travelled by motor-vehicles for intelligent motor-vehicle driving speed control along roads.
The motor-vehicles are configured to transmit data allowing anomalous situations to be recognised along roads travelled by the motor-vehicles.
The system comprises data processing resources configured to:
receive and process data transmitted by the motor-vehicles to recognise anomalous situations along the roads travelled by the motor-vehicles based on a recognition algorithm,
when anomalous situations are recognised along roads travelled by the motor-vehicles, generate associated alert events and compute reference driving speeds along the roads recognised to be affected by anomalous situations, and
transmit data representative of the alert events and of the reference driving speeds along the roads recognised to be affected by anomalous situations.
The motor-vehicles are further configured to:
receive data representative of alert events and reference driving speeds, and
use the received data to implement one or both of the following actions: inform the drivers of motor-vehicles, through automotive user interfaces of motor-vehicles of the anomalous situations recognised along roads travelled by motor-vehicles, and cause current driving speeds of the motor-vehicles to be adjusted to the reference driving speeds along roads recognised to be affected by anomalous situations.

SYSTEM FOR DISPLAYING ATTENTION TO NEARBY VEHICLES AND METHOD FOR PROVIDING AN ALARM USING THE SAME
At least one nearby vehicle may be extracted from a vehicle vicinity image collected by a sensor equipped in the target vehicle. Lane recognition information representing which one position a position of the extracted nearby vehicle corresponds to with respect to the target vehicle, and/or vehicle position information representing a relative distance from the target vehicle to the nearby vehicle may be identified. An attention degree of the nearby vehicle may be calculated based on a speed of the nearby vehicle calculated from the relative distance and a vehicle speed of the target vehicle, the vehicle position information of the nearby vehicle, the relative distance of the nearby vehicle, the speed of the target vehicle, or any combination thereof. An alarm for the nearby vehicle may be displayed on a screen according to the calculated attention.
METHOD AND APPARATUS FOR ASSESSING TRAFFIC IMPACT CAUSED BY INDIVIDUAL DRIVING BEHAVIORS
An approach is provided for accessing traffic impact caused by individual driving behaviors. For example, the approach involves receiving, by one or more processors, sensor data collected from one or more sensors of a vehicle traveling on a road network. The approach also involves processing, by the processors, the sensor data to determine one or more driving behaviors associated with the vehicle. The approach further involves computing, by the processors, a traffic impact index based on the one or more driving behaviors and at least one contextual parameter associated with the vehicle, the road network, a driver of the vehicle, or a combination thereof. The traffic impact index represents an estimated impact of the vehicle on a traffic flow within at least a portion of the road network. The approach further involves providing, by the processors, the traffic impact index as an output.
