Abstract
Systems and methods are provided and include a sensor that is configured to generate a first link key data packet. A control module of a vehicle is configured to generate a second link key data packet. In response to (i) a first authenticated response of the first link key data packet matching a second authenticated response of the second link key data packet and (ii) a user device being connected to a communication gateway of the control module by a Bluetooth low energy (BLE) communication link, the sensor is configured to communicate signal information to the control module using a hardwire link that electrically couples the control module and the sensor. The signal information includes information corresponding to physical characteristics of the BLE communication link.
Claims20
A system comprising:
- a sensor that is configured to generate a first link key data packet;
- a control module of a vehicle, wherein the control module is configured to generate a second link key data packet;
- and
- in response to (i) a first authenticated response of the first link key data packet matching a second authenticated response of the second link key data packet and (ii) a user device being connected to a communication gateway of the control module by a wireless communication link, the sensor is configured to communicate signal information to the control module using a hardwire link that electrically couples the control module and the sensor, wherein the signal information includes information corresponding to characteristics of communication signals sent via the wireless communication link.
A method comprising:
- generating, using a sensor, a first link key data packet;
- generating, using a control module of a vehicle, a second link key data packet, wherein the control module includes at least one processor that is configured to execute instructions stored in a nontransitory memory;
- determining, using the control module, whether a first authenticated response of the first link key data packet matches a second authenticated response of the second link key data packet;
- determining, using the control module, whether a user device is connected to a communication gateway of the control module by a wireless communication link;
- and
- in response to (i) the first authenticated response matching the second authenticated response and (ii) the user device being connected to the communication gateway of the control module by the wireless communication link, communicating, using the sensor, signal information to the control module using a hardwire link that electrically couples the control module and the sensor, wherein the signal information includes information corresponding to characteristics of communication signals sent via the wireless communication link.
