Abstract
Method and apparatus are disclosed for reducing power consumption in a PAAK vehicle system. An example vehicle includes a main BLE module for communication with a mobile device acting as a vehicle key, a plurality of BLE antenna modules (BLEAMs), and a processor. The processor is configured for determining that the mobile device is within a threshold range of the vehicle for a threshold time period, and responsively reducing power consumption of one or more of the plurality of BLEAMs.
Claims20
A vehicle comprising:
- a main BLE module for communication with a mobile device acting as a vehicle key;
- a plurality of BLE antenna modules (BLEAMs);
- and
- a processor for:
- responsive to determining that the mobile device is within a threshold distance from the main BLE module to a location outside the vehicle for a threshold time period,
- reducing a power consumption of one or more of the plurality of BLEAMs.
A method of reducing vehicle power consumption comprising:
- establishing communication between a main BLE module of a vehicle and a mobile device acting as a vehicle key;
- and
- responsive to determining, by a vehicle processor, that the mobile device is within a threshold distance from the main BLE module to a location outside the vehicle for a threshold time period,
- reducing a power consumption of at least one BLE antenna module (BLEAM) of the vehicle,
- wherein the vehicle comprises a main BLE module for communication with the mobile device and a plurality of BLEAMs.
A vehicle comprising:
- a main BLE module for receiving a signal from a mobile device acting as a vehicle key;
- a plurality of BLE antenna modules (BLEAMs);
- and
- a processor for:
- responsive to determining that a strength of the signal is at or above a threshold level for a threshold time period, reducing a power consumption of one or more of the plurality of BLEAMs, the threshold level corresponding to a signal strength established when the mobile device is positioned outside the vehicle and at a predetermined distance from the main BLE module.
