Abstract: 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.

Abstract: 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.
