Gnss phone-based automated emergency assistance calling for vehicular applications

Abstract

A phone device monitors an accelerometer while traveling in a vehicle to detect unusually large excursions or sudden changes in acceleration magnitude. When such an excursion is detected, the phone device then compares the excursion with the output of other components in the vehicle that can confirm or dispel a finding that the vehicle has experienced a collision. Once a likely collision has been detected, the phone device goes into an automated assistance mode where the use can be voice prompted as to their condition. If no response is received, the phone device can automatically call emergency services for assistance, providing the present location of the phone device. In less severe incidents, the phone device can automatically offer immediate access to other services, include a towing service, an attorney, an automobile service, among others. The service providers are based on a geo-fenced region in which the phone device is located.
