Abstract
A system for performing an operation in a vehicle is disclosed. The system includes a Bluetooth Low Energy (BLE) module, a microcontroller coupled to the BLE module and a transmitter/receiver coupled to the microcontroller. The microcontroller is configured to transmit a wakeup signal at preselected intervals to wake up an electronic key and measure received low frequency (LF) signal strength and Bluetooth signal strength transmitted from the electronic key and based on measured signal strengths determine if the electronic key is approaching the vehicle and to perform a preselected vehicle operation on the vehicle.
