This application discloses a data fusion method and a related device. The method includes: obtaining vehicle sensing data, where the vehicle sensing data is obtained by a vehicle sensing apparatus by sensing a road environment in a sensing range by using a vehicle sensor; obtaining roadside sensing data, where the roadside sensing data is obtained by a roadside sensing apparatus by sensing a road environment in a sensing range by using a roadside sensor; and fusing the vehicle sensing data and the roadside sensing data by using a fusion formula, to obtain a first fusion result. According to the foregoing solution, overlapping can be implemented between the sensing range of the roadside sensing apparatus and the sensing range of the vehicle sensing apparatus can be implemented, so that the sensing range is effectively extended.

A cellular network-based assisted driving method and a traffic control unit are provided, to accurately assess a risk and provide a valuable safety warning for a vehicle. In various embodiment, a first about-to-occur track of a first vehicle is determined based on traveling status information of the first vehicle. The first about-to-occur track is a traveling track of the first vehicle that is to occur within preset duration from a current moment. Warning information can be sent to the first vehicle when it is determined that a second about-to-occur track of a second vehicle intersects the first about-to-occur track. The second about-to-occur track is a traveling track of the second vehicle that is to occur within the preset duration from the current moment.

Cellular network-based assisted driving method and traffic control unit

Embodiments of the present invention provide a traffic control method and an apparatus. The method includes: obtaining, by a server, a traffic flow of a road; adjusting, by the server, a lane quantity or a lane width of the road at a lane layer on a map according to the traffic flow of the road; and sending, by the server, a lane layer obtained after the adjustment, so that a vehicle running on the road runs according to a lane obtained after the adjustment. In the embodiments of the present invention, the traffic flow of the road is obtained, and the lane quantity or the lane width of the road is adjusted at the lane layer on the map according to the traffic flow of the road, so that the vehicle running on the road can run according to the lane obtained after the adjustment.

Traffic control method, and apparatus

Embodiments of the present invention provide a method for switching a roadside navigation unit in a navigation system. The method includes: receiving, by an OBU, a switching notification message from a first RSU, where the switching notification message is used to instruct the OBU to prepare to switch a home RSU of the OBU from the first RSU to a second RSU; sending, by the OBU, a registration request to the second RSU to request to obtain local path information of the OBU within a coverage area of the second RSU; receiving, by the OBU, the local path information; and switching, by the OBU, the home RSU of the OBU from the first RSU to the second RSU according to the local path information.

Method for switching roadside navigation unit in navigation system, and device

The present invention provides a navigation system, apparatus, and method. The navigation system includes a global navigation apparatus, a first roadside navigation apparatus, and a terminal navigation apparatus. The terminal navigation apparatus is configured to send, to the global navigation apparatus, a global path request used to request for a road-level global path. The global navigation apparatus is configured to: determine the global path according to the global path request, and send, to the terminal navigation apparatus, first indication information used to indicate the global path. The first roadside navigation apparatus is configured to: determine a lane-level local path according to the global path, and send, to the terminal navigation apparatus, second indication information used to indicate the local path.

This invention relates to a method of automatic recognition for limited speech and its correlative system and device. The main technical content is: Establish the relationship between the voice file and the identification information for a limited range of speech, and then insert the identification information into the voice file, or replace the content of the voice file with the identification information. After the transmitter sends the modified voice file, the receiver receives the modified voice and distinguishes the identification information in the voice. It then extracts the corresponding speech in the predetermined relationship using this identification information. The benefits of the embodiment of this invention include: a lower-cost method for automatically recognizing limited speech; high efficiency speech recognition, no need to wait for the voice file to finish to complete speech recognition; and lastly, a high recognition hit-rate or accuracy rate.
