Abstract
A vehicle communication system includes a computer processor in communication with persistent and non-persistent memory. The system also includes a local wireless transceiver in communication with the computer processor and configured to communicate wirelessly with a cellular telephone located at the vehicle. The system further includes a backup power circuit comprising a charge storage device such as a local battery or capacitor having enough charge to power the computer processor and local wireless transceiver long enough to send an emergency call signal to the cellular telephone, and an emergency call command signal is sent from the local wireless transceiver to the cellular telephone in the event a vehicle emergency is detected at the computer processor and vehicle power is lost. The signal causes the cellular telephone to place or continue an emergency call to an emergency responder or agency over the cellular telephone network.
