The present disclosure discloses a method for Internet of Vehicles (IoV) electronic traffic sign information broadcast with Quality of Service (QoS) guaranteed mechanism based on conflict detection. Compared with the traditional WLAN applied in electronic traffic sign information broadcast, the present disclosure significantly reduces the information broadcast delay, and at the same time provide QoS guaranteed service for the information broadcast. It allows IoV, through distributed algorithm, to achieve the electronic traffic sign information broadcast with self-organization framework, short transmission delay and high efficiency.

Method for encoding/decoding a signal at a first and second communication node (N1; N2) in a road vehicle. A signal (1) from an on-board sensor (10) is encoded using a first encoding scheme (a), encoding the formed single encoded sensor signal (1a) using a second encoding scheme (b), decoding this double encoded sensor signal (1ab) in the second communication node (N2) based on the second encoding scheme (b), forming a decoded single encoded sensor signal (1a). In the first communication node (N2), performing a comparison analysis, comprising at least one of the following: comparing the decoded single encoded sensor signal (1a) with a stored single encoded sensor signal (1a), or after encoding the decoded single encoded sensor signal (1a) with the second encoding scheme (b) comparing (110) the thus formed double encoded sensor signal (1ab) with a stored double encoded sensor signal (1ab). If the compared sensor signals (1a,1a, 1 ab,1ab) match, then sending (111) a signal to the second communication node (N2) validating the sensor signal (1), and if they do not match, then initiating (112) a corrective action.

A vehicle system includes a plurality of electronic control devices respectively includes a first processor configured to control each unit of a vehicle; and a management electronic control device that includes a second processor configured to manage the plurality of electronic control devices, wherein when an encryption key used to verify a message is updated to another encryption key, the second processor transmits a first message that includes a controller area network identifier (CAN-ID) that identifies the message and a second message that includes the another encryption key to a network, and when the CAN-ID of the message included in the first message is a CAN-ID to be processed, the first processor updates the encryption key used to verify the message to the another encryption key included in the second message.

Disclosed is a connectivity matrix that wireless entities (vehicles, fixed assets, etc.) can display indicating the 5G/6G wireless address of the entity. Other wireless devices can then image the connectivity matrix, determine the wireless address, and then communicate in sidelink, on frequencies allocated for ad-hoc networking. Alternatively, the two entities can communicate through a local base station, on managed channels, using the displayed wireless address. The matrix can provide additional information, such as the frequency, bandwidth, and modulation scheme favored by the entity. Alternatively, the matrix can provide a key code maintained by a central authority, so that a second wireless entity can read the code and request the associated wireless address (and frequency, bandwidth, etc.) from the central authority. By either method, the two wireless entities can then communicate explicitly thereafter.

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.

An apparatus and method are provided for supporting vehicle-to-vehicle communication utilizing a base station. Included is a vehicular network interface configured to receive, from a first subset of a set of vehicles, first messages.
