Abstract

The use of sound pattern matching methods and techniques to analyse driver behavior and accidents and provide alerts to drivers, passengers, insurers or accident management companies. While a driver is operating a vehicle on the road, sound signatures are captured from a smartphone, in car microphone, retrofitted telematics unit or other device with audio capture capabilities. The sound signatures captured are recorded, analysed and matched against known and/or previously recorded sound patterns to help determine circumstances relating to a vehicle accident event or incident. Examples of recorded and matched sound signatures include the “rumbling” sound when driving over cats eyes or edging strips on roads, the skidding sound when braking harshly or an airbag explosion.

Claims

1. A method comprising:

receiving a stream of sound related data;

Analysing and comparing elements of the data against a library of sound profiles or signatures;

The data may be collected from several sources, including but not limited to;

1.1 An in-car microphone

1.2 A telematics unit fitted to the car

1.3 A smartphone with software designed to capture ambient (background) noise

4. The matching techniques used to identify potential matches between captured data as in claim 1 and the known sound profiles as in claim 2

2. A library of previously collated sound signatures or profiles related but not limited to;

2.1 Driver behavior including but not limited to, rumbling noise pattern when driving over cats eyes or when driving over textured edging strips on roads

2.2 a vehicle'"'"'s tyres skidding on the road surface due to hard braking

2.3 the noise of an airbag inflating during an accident

2.4 the noise from the vehicle due to an impact

3. The storing and indexing of the collated data and related information

5. The software that provides feedback to the driver or passengers in the vehicle which may be through an audio, visual, text SMS, email, instant message, web-services connection or any other means

6. The software that provides feedback to the insurance company providing cover for the driver or passengers in the vehicle concerned. which may be through an audio, visual, text SMS, email, instant message, web-services connection or any other means

7. The software that provides feedback to any third party organization with an interest in the driver behavior during a journey or immediately before, during or and after an accident or incident, which may be through an audio, visual, text SMS, email, instant message, web-services connection or any other method
