Vehicle security with accident notification and embedded driver analytics

摘要

The present invention relates to a vehicle telematics device with one or more cameras embedded in the same package for evidentiary surround audio-video recording, automatic accident detection and emergency help request notification, facial processing for drowsiness and distraction accident avoidance, and embedded multiple profiles of driver analytics, and mobile internet connectivity for contacting emergency services directly and without the delay of a call center and for mobile hot spot for in-vehicle infotainment. Each profile of driver analytics has many selectable advanced driver analysis parameters and multiple profiles can be active for a given driver. In case of emergency help request accident panoramic accident video is uploaded to a cloud drop box and link to video of accident is available along with severity index, location, nearest address, number of passengers, etc.

1. A method for detecting a vehicle accident and notifying emergency services in case an accident is detected, said method comprising:
determining unloaded weight of a vehicle in accordance with make and model of vehicle selected; selecting threshold values of accident detection parameters in accordance with the determined unloaded weight of the vehicle; calculating a series of acceleration vector values in accordance with inputs from an X-Y-Z accelerometer; filtering said acceleration vector values; calculating a severity index (SI) value, width of peak of said acceleration vector, and an average acceleration value and duration of time around a peak acceleration event; determining occurrence of a severe accident; connecting to wireless broadband network when the accident is detected; determining a location information in terms of latitude and longitude based on GPS inputs; determining a nearest address based on said location information; calculating a scaled severity index (SI) of accident; capturing an accident video using multiple cameras from several seconds before the accident to some seconds after the accident in a standard compressed video file format; uploading said captured accident video to a drop box in a cloud storage, and providing a URL link to access it in an emergency help request message; composing an emergency help request message which includes accident information including said scaled severity index value, location and time of accident, vehicle information, said nearest address, and link to accident video; and sending said emergency help request message to IP based emergency services of Public Safety Answering (PSAP) that has jurisdiction over a caller's location, using a messaging system that includes but not limited to one of SMS 911, NG-9-1-1, and eCall.
