PASSIVE ENTRY PASSIVE START DEVICE PROVIDING WIRELESS CHARGER RESOURCES AND METHOD TO OPERATE SUCH A DEVICE

摘要

An electronic device (ED) for controlling access to a vehicle using a portable identifier and for providing power to a portable device inside that vehicle comprises a plurality of external low frequency antenna (LA), a radio receiver (TRC) and a wireless charger (WIC). The electronic device (ED) operates in at least two mutually exclusive modes: a first mode where the electronic device (ED) sends a high- power signal to a portable identifier and exchanges data with said portable identifier using the radio receiver and the external low frequency antenna (LA); a second mode where the electronic device (ED) detects a portable device placed nearby the wireless charger (WIC), exchanges data and provides power to the portable device using a high power signal through the wireless charger (WIC).
