Abstract: A method of controlling a wireless hotspot at a vehicle includes receiving one or more Wi-Fi control variables along with a vehicle identity at a central facility; authenticating the received Wi-Fi control variables at the central facility using the vehicle identity; establishing a cellular connection between the central facility and a vehicle providing the Wi-Fi hotspot identified by the transmitted vehicle identity; and transmitting a command to change the Wi-Fi control variables from the central facility to the vehicle when the Wi-Fi control variables have been authenticated.

Abstract: A method of extending connectivity of a recipient vehicle may be executed by a non-transitory computer-readable medium. During an ignition off state of the recipient vehicle, the method includes disabling a recipient cellular network access device (NAD) of the recipient vehicle and connecting to a low power communications source. The method includes communicating with a centralized location over the low power communications source. The low power communications source may be a recipient Bluetooth® low energy (BLE) within the recipient vehicle. The method may include connecting to a donor vehicle proximate the recipient vehicle. The donor vehicle includes a donor NAD and a donor BLE, such that the donor NAD of the donor vehicle communicates with the centralized location on behalf of the recipient vehicle.

Abstract: A location assistance system includes a distress vehicle and multiple assistance vehicles. The distress vehicle broadcasts an emergency signal. The assistance vehicles are operable to receive the emergency signal, determine multiple distances to the distress vehicle, triangulate among the assistance vehicles to generate a spatial map of the distress vehicle relative to the assistance vehicles, determine one or more approximately horizontal lines in the spatial map that include the distress vehicle and at least one horizontally aligned assistance vehicle in response to the distress vehicle and the at least one horizontally aligned assistance vehicle being on a same vertical level in the spatial map, coordinate among the assistance vehicles to determine one or more horizontal sequences along the one or more approximately horizontal lines, and flash the of the assistance vehicles in the one or more horizontal sequences to lead toward the distress vehicle.

Abstract: A telematics controller, a second controller, a dual-function audio speaker, and a switch are included. The telematics controller is in communication with a first microphone. The telematics controller includes a first amplifier, and is configured to communicate with a remote facility. The second controller includes a second amplifier and a second microphone. The switch is arranged in the telematics controller, and an electrical link is arranged between the second controller and the telematics controller. The dual-function audio speaker is selectively connectable to the second amplifier via the switch and the electrical link. The dual-function audio speaker is also selectively connectable to the first amplifier via the switch. The switch is operatively controlled by the telematics controller, and the telematics controller is operative to control the switch to control the dual-function audio speaker to effect wireless audio communication between the vehicle and the remote facility.

Abstract: A crash detection system for a vehicle comprises first and second batteries and a computational system comprising a processor and a non-transitory computer-readable medium. First and second antennas are both in electronic communication with the computational system and powered by one of the batteries, with the antennas configured to independently wirelessly communicate with an external network. A microphone powered by one of the batteries and in electronic communication with the computational system. The microphone continuously receives sound waves in real time and transmits sound signals to the processor. The processor monitors properties of the sound waves within the sound signals, compares the properties to thresholds stored in the non-transitory computer-readable medium, determines if the vehicle has been involved in a collision if at least one of the properties crosses the respective threshold, and communicates with the external network to report the collision with one of the antennas.

Abstract: A system for processing an SMS message transmitted between a vehicle telematics unit and a call center and a method of processing an SMS message using the system. The method includes the steps of: receiving an SMS message having security data, wherein both a header and a payload of the SMS message carry the security data; attempting to authenticate the security data; accepting the SMS message if the security data is authenticated, and ignoring the contents of the SMS message if the security data is not authenticated.
