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: An in-vehicle system is described that initiates a telematics service call via a touch-based user interface. The in-vehicle system includes a telematics unit that supports communications relating to telematics services, an infotainment center, and a touchscreen interface configured to present user-selectable controls for invoking services provided by the infotainment center and the telematics unit. The system further comprises a backup battery configured to supply power, during a disruption of power supply from a primary power supply, to: the touchscreen interface, the telematics unit, and a microphone/speaker providing bi-directional audio communications with providers of telematics services. The system furthermore includes a backup battery mode control configured to sense a disruption of power provided by the primary power supply. In response to the disruption, the mode control activates a low-power operating mode for the touchscreen interface.
