Accident Detection System

The accident detection system with smartphones is independent of vehicle based detection system and uses two or three sensors in smartphones - the system collect the data provided by the smartphones during the accident and send collected information to a central data bank server over a network connection. It can work as immediate helping system. This data bank can only be accessed by licensed authorities, e.g., such as insurance companies or hospitals. Similarly, describe a system that provide information about current status of the object - in terms of location and its positioning. This status alerts the concerned family member or friend who is having that application in her/his smartphones or to a hospital if it having the server connection.

Eliminating time between when an accident occurred and when first medical personnel dispatched to the accident location. Fig 1.1 shows how formal accident detection system works.In traditional accident detection system sensors uses a built -in cellular radio to send information to the monitoring center that is responsible for dispatching medical personnel for instance help. unfortunately , most cars in US and in other countries do not have this accident detection and notification system. Few years back some automobile companies made this system as a mandatory option in their vehicles and most other companies do not include this as a standard option. A key obstruction in using this system they are infeasible and expensive to install in existing vehicles and add to the initial cost of the

Building a smartphone based system in vehicles in tough and sometimes may be dropped somewhere and the phone is not directly connected to the car. In contrast, vehicle accident detection system rarely acquire false positives because they depend upon sensors, such as airbag sensors that directly find damage to the car.

2. Conflicts associated with automatically detecting car accidents:

This section discuss the conflicts associated with detecting vehicle accidents via software installed on smartphones. A key challenge in designing software to detect accident is the inadequacy of integration between the smartphone and the car. In contrast, in-vehicle accident detection system depend upon sensors provided in the vehicle.

1.Detecting accident without Electronic Control Unit (ECU) communication.

Vehicle based accident detection system depend upon sensors network in the car and has direct interaction with the electronic control unit. These sensors detect acceleration, forces and orientation experienced by the vehicle during the accident and develop a detailed accident profile, such as location of the vehicle and number of times it was
