In embodiments, Bluetooth® proximity sensors installed in a vehicle are configured to pair with a user mobile device and estimate distances to the user mobile device based on signal strength of the Bluetooth® emissions of the user mobile device. Each sensor, communicates its distance estimates to a vehicle control system (VCS) of the vehicle, using Bluetooth® communications. In response to the distance acre tying above a predetermined distance departure limit, the VCS causes predetermined departure actions to be performed, for example, locking the doors, turning off headlights, and activating the vehicle's security system. In response to the distance decreasing below a predetermined distance arrival limit, the VCS causes predetermined arrival actions to be performed, for example, unlocking the doors, flashing the headlights, beeping the horn, and deactivating the security system.
