1. A method for managing a vehicle calibration database, comprising the following steps:
A. generating a calibration database comprising one or more sets of calibration data and a default label set associated with each set of calibration data;
B. in response to a calibration request, obtaining a current label set associated with a user account from a vehicle end and a digital key end;
C. separately calculating relevances between the current label set and the one or more default label sets;
D. selecting a set of calibration data from the calibration database based at least on the relevances as calibration data to be distributed;
E. transmitting the selected set of calibration data to the vehicle end and the digital key end for use in a calibration process, with the selected set of calibration data being used to improve a positioning accuracy of the digital key end as determined by the vehicle end during the calibration process;
F. obtaining positioning parameters in the calibration process from the vehicle end and the digital key end;
G. training a ranging model using the positioning parameters, and generating new calibration data based on the ranging model; and
H. updating the calibration database with the new calibration data.
