A method for providing driving assistance based on a HD map includes acquiring information such as position of a vehicle and timing, and acquiring a speed of the vehicle based on the manner of driving, and acquiring distance an intersection in front of the vehicle and information from a HD map such as traffic light intersection ahead. Deciding such as whether the vehicle can pass through the intersection based on the speed of the vehicle, intersection distance, and the traffic light information and prompting and/or controlling the vehicle if it is determined that passage through is not possible. A vehicle-mounted apparatus applying the method is also disclosed.

Embodiments of the present disclosure provide a method, an apparatus and a device for an illegal vehicle warning. The method includes: detecting an illegal vehicle in a preset area; and performing the illegal vehicle warning on a target vehicle entering the preset area according to vehicle information of a detected illegal vehicle in the preset area. In the embodiments of the present disclosure, the traffic control unit detects the illegal vehicle in the preset area, and the illegal vehicle warning is performed on the target vehicle entering the preset area according to the vehicle information of the detected illegal vehicle in the preset area, thereby avoiding or mitigating the collision of the target vehicle with the illegal vehicle, and improving the traffic safety of the target vehicle.

An in-vehicle wireless communication device according to the present embodiment is is mounted in a vehicle and includes a wireless communication unit that performs wireless communication with an external device provided outside of the vehicle and a processing unit that performs processing relating to communication, in which the processing unit determines a communication amount in an in-vehicle network provided inside of the vehicle, transmits communication amount information relating to the determined communication amount to the external device by the wireless communication unit, and receives data transmitted from the external device at a size corresponding to the transmitted communication amount information, by the wireless communication unit.

A method for controlling a flow of traffic on a roundabout, wherein the flow of traffic is controlled by a traffic control unit by which road users that have entered the roundabout and/or are approaching the roundabout in order to enter it are networked in a network and communicate by way of messages, and wherein, in order to enter, a road user transmits a message containing a request to the traffic control unit provides for entry by the respective road user to be preceded by the flow of traffic that is on the roundabout being determined on the basis of the messages, wherein a message containing a control signal is generated for the respective entering road user in order to communicate whether and/or along which route the road user can travel on the roundabout.

Methods and systems for autonomous and semi-autonomous vehicle control, routing, and automatic feature adjustment are disclosed. Sensors associated with autonomous operation features may be utilized to search an area for missing persons, stolen vehicles, or similar persons or items of interest. Sensor data associated with the features may be automatically collected and analyzed to passively search for missing persons or vehicles without vehicle operator involvement. Search criteria may be determined by a remote server and communicated to a plurality of vehicles within a search area. In response to which, sensor data may be collected and analyzed by the vehicles. When sensor data generated by a vehicle matches the search criteria, the vehicle may communicate the information to the remote server.

A control method for a first moving body includes: acquiring, from a second moving body, emergency information that includes information on a scheduled route on which an emergency vehicle travels in an emergency; and transmitting, by device-to-device communication, the emergency information to a third moving body that is predicted to travel on the scheduled route.

Systems and techniques are described for consuming data in an intelligent transport system. In some implementations, a system includes a display screen device and sensors. The sensors generates data describing sensor observations of a roadway at a first location and provides data describing the observations to the display screen device. The display screen device receives the data and determines an event and a type of the event. The display screen device displays second data indicative of the type of event, the second data being of a format that is consumable by a sensor on a vehicle traversing the roadway towards the first location, the sensor (i) located within a first resolution distance from the display screen device and (ii) located outside a second resolution distance of detecting the event, wherein the second data is used by an on-board processing system of the vehicle to adjust its driving behavior.

The present invention relates to the guidance of autonomous vehicles and in particular, relates to guiding an autonomous vehicle along a roadway by means of active devices with a system which works during normal and inclement, weather as well as under any luminous conditions, These active devices are embedded in the passive and/or active road details such as traffic signs, traffic lights, warning lights etc. These active devices provide data relating to road conditions, speed, road layout etc. as well as other information such as availability of parking spaces. Accordingly, through networks of sensors and devices the autonomous vehicle can obtain road details in real-time in any weather, illumination, visibility etc.

The present invention relates to a method for providing a route stipulation for a route system of a vehicle, comprising the following steps: providing a plurality of detected trajectories of further vehicles in a route section to be used, ascertaining a trajectory stipulation from the detected trajectories, ascertaining a deviation zone from the detected trajectories, wherein the deviation zone is determined on the basis of a deviation of at least individual detected trajectories from the trajectory stipulation, determining the route stipulation at least on the basis of the trajectory stipulation and the deviation zone.

A method of directing traffic flow includes receiving, by a processor, navigation information from a vehicle in a multi-edge communication network, and receiving, by the processor, a status of an edge node traffic control device of the multi-edge communication network. The edge node traffic control device is configured to regulate traffic flow on a path segment. The method includes determining, by the processor, a navigation command based on the navigation information and the status, and outputting, by the processor, the navigation command to the vehicle through the multi-edge communication network.
