Patent attributes
A computer-implemented method includes determining a connection status of a first attempted connection between a mobile device comprising a Phone-as-a-Key (PaaK) controller and a first Bluetooth Low-Energy (BLE) module of a target vehicle. The mobile device selects, based on the connection status, a relay vehicle associated with the PaaK controller and the target vehicle. The relay vehicle includes a second BLE module. The mobile device may establish a second connection between the mobile device and a second BLE module of the relay vehicle, and transmit a power mode instruction to the target vehicle via the second connection between the mobile device and the second BLE installed in the relay vehicle. The second connection enables the second BLE module to relay the power mode instruction to the target vehicle, and the power mode instruction enables the target vehicle to execute a key-on operation.
