IN-VEHICLE USER POSITIONING METHOD, IN-VEHICLE INTERACTION METHOD, AND VEHICLE-MOUNTED APPARRATUS

This application provides an in-vehicle user positioning method, an in-vehicle interaction method, a vehicle-mounted apparatus, and a vehicle, applied to the field of autonomous driving. The in-vehicle user positioning method includes: obtaining a sound signal collected by an in-vehicle microphone; when a first voice command is recognized from the sound signal, determining a first user who sends the first voice command; and determining an in-vehicle location of the first user based on a mapping relationship between an in-vehicle user and an in-vehicle location. According to the solution of this application, a user who needs to interact can be determined according to a voice command, and then an in-vehicle location of the user who needs to interact can be determined based on the mapping relationship between an in-vehicle user and an in-vehicle location. Even if a plurality of users speak at the same time, the user who needs to interact can be located.
