PORTABLE DEVICE FOR UNLOCKING VEHICLE, METHOD, AND STORAGE MEDIUM

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. The portable device for unlocking a vehicle proposed in the disclosure can switch its operating mode in response to a change in the motion status and the ambient temperature, thereby solving a problem of fast power consumption and a short service life of a smart key, and solving a problem of failure of a function of the smart key at high temperature in summer or at low temperature in winter.
