Abstract
A digital vehicle key positioning method in the field of vehicle control technologies includes receiving location information from a terminal device at a vehicle, and determining location information of a digital vehicle key relative to the vehicle based on the location information of the terminal device and wireless signals respectively collected by a plurality of short-range wireless communication modules in the vehicle. The location information that is determined by the terminal device and the wireless signals collected by the vehicle are fused to implement more precise positioning of the digital vehicle key.
