Abstract
Systems and methods include a communication gateway in a vehicle configured to establish a Bluetooth low energy (BLE) communication connection with a portable device and to instruct at least one sensor to perform ranging using impulse radio (IR) ultra-wide band (UWB) communication with the portable device based on information exchanged with the portable device via the BLE communication connection. A localization module configured to determine a location of the portable device based on the ranging performed by the at least one sensor with the portable device.
Claims28
A system comprising:
- a communication gateway in a vehicle configured to establish a Bluetooth low energy (BLE) communication connection with a portable device and to instruct at least one sensor to perform ranging using impulse radio (IR) ultra-wide band (UWB) communication with the portable device based on information exchanged with the portable device via the BLE communication connection;
- and
- a localization module configured to determine a location of the portable device based on the ranging performed by the at least one sensor with the portable device.
A method comprising:
- establishing, with a communication gateway in a vehicle, a Bluetooth low energy (BLE) communication connection with a portable device;
- instructing, with the communication gateway, at least one sensor to perform ranging using impulse radio (IR) ultra-wide band (UWB) communication with the portable device based on information exchanged with the portable device via the BLE communication connection;
- and
- determining, with a localization module, a location of the portable device based on the ranging performed by the at least one sensor with the portable device.
