1. A vehicle control method, performed by an on-board terminal and comprising:
in response to obtaining a target received signal strength indication (RSSI) value of ranging broadcast information sent by a mobile terminal, obtaining a target mapping relationship matching a device model of the mobile terminal, wherein the target mapping relationship comprises a mapping relationship between a RSSI value and a distance between the mobile terminal and a vehicle;
based on the target mapping relationship, determining a target distance corresponding to the target RSSI value;
in response to determining that the target distance is less than or equal to a preset distance threshold, controlling the vehicle associated with the on-board terminal to unlock a door lock; and
storing the target mapping relationship in advance in a local memory of the on-board terminal by:
obtaining a reference RSSI value of the ranging broadcast information sent by the mobile terminal at a reference position, wherein the reference position is any one of at least one reference position, and a distance between each of the at least one reference position and the vehicle is known;
based on the reference RSSI value and a corresponding distance between the reference position and the vehicle, correcting a currently-stored to-be-corrected mapping relationship to obtain a corrected mapping relationship; and
determining the corrected mapping relationship as the target mapping relationship matching the device model of the mobile terminal, and storing the target mapping relationship in the local memory of the on-board terminal.
