Abstract: A terminal device includes a processor, a direct stream digital (DSD) audio playback circuit, and a headset jack. The processor is connected to the DSD audio playback circuit, and the DSD audio playback circuit is connected to the headset jack. The processor outputs a DSD audio signal to the DSD audio playback circuit in response to triggering performed by a user. The DSD audio playback circuit is configured to process the DSD audio signal, generate an alert tone based on a current scenario, and superpose the processed DSD audio signal and the alert tone. The headset jack is configured to connect to a headset and play the superposed audio signal and alert tone using the headset.

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.

Abstract: An audio output channel switching method is applied to an electronic device having a built-in earpiece and a first sensor. The first sensor is disposed at a first location in the electronic device. The electronic device having an external audio device connected thereto as an audio output channel detects a first operation. In response to the first operation, the electronic device determines a first distance between the electronic device and the external audio device. The electronic device determines a second distance between a covering object and a first location based on a detection signal of the first sensor. When the first distance is greater than a first distance threshold, and the second distance is less than a second distance threshold, the electronic device switches the audio output channel from the external audio device to a built-in earpiece of the electronic device.

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.
