Abstract: The disclosure relates to a method and an apparatus for managing a vehicle calibration database, and a storage medium. The portable device includes a communication unit and a processing unit. The method includes: A. generating a calibration database including 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; and D. selecting a set of calibration data from the calibration database based at least on the relevances as calibration data to be distributed.

Abstract: The disclosure relates to a portable device for unlocking a vehicle, a method, and a storage medium. The portable device includes a communication unit and a processing unit. The communication unit is configured to scan a pairing request signal from the vehicle, and transmit a locking/unlocking signal to the vehicle. The processing unit is configured to: receive a motion status signal indicating a motion status of the portable device and a temperature signal indicating an ambient temperature of the portable device; and switch an operating mode of the portable device based on at least one of the motion status signal and the temperature signal.
