Abstract

The present invention relates to the field of vehicle control technology, and provides a vehicle control system based on Bluetooth communication, including: an antenna module arranged on the vehicle; the antenna module is communicatively connected with a vehicle body controller BCM; a Bluetooth antenna arranged on a mobile terminal, and the Bluetooth antenna communicates with the antenna module via Bluetooth; the Bluetooth antenna on the mobile terminal periodically transmits a Bluetooth signal outward, and the antenna module determines the distance between the mobile terminal and the corresponding antenna module based on the signal strength of the received Bluetooth signal, and uses the distance between the mobile terminal and the corresponding antenna module as the distance between the mobile terminal and the vehicle, and triggers the corresponding function of the vehicle when the distance between the mobile terminal and the vehicle enters the corresponding function circle of the vehicle. The ranging of the mobile terminal is realized based on the field strength value characteristic of Bluetooth, and the owner can actively welcome guests, unlock, and lock the vehicle by carrying the mobile terminal, providing greater comfort and convenience for the owner's life and entertainment, and the vehicle can also be unlocked when the owner forgets to carry the car key.
