VEHICLE ACCIDENT DETECTION AND NOTIFICATION
Technical Field of the Invention
The present invention relates to detection of vehicle accidents. In particular, the present invention relates to a device operable to monitor vehicle activity, detect vehicle 5 accidents and automatically notify details of the accident to trusted remote devices.
Background to the Invention
In the course of normal operation, it is not uncommon for road vehicles to be involved in various incidents typically referred to as accidents (or road traffic accidents) whereby the vehicle collides with another road vehicle, collides with a stationary object on or adjacent to a road, overturns and/or suffers a significant mechanical failure. Where a driver or passenger involved in the incident is uninjured or where there are other nearby persons, the occurrence of the incident can be readily reported to the appropriate authorities and/or the emergency services. Where all persons involved or nearby to an accident are injured, there can be considerable difficulties or delays in 15 summoning assistance. Where injured parties are able to summon help, they may not accurately be able to describe the location of the accident or its severity.
In the aftermath of an accident, there may be an investigation into the circumstances of the accident. This may be initiated by the police if criminal liability is at issue. Alternatively, this investigation may be carried out by a person involved in the incident, their legal representatives or insurance company where civil liability is at issue. Whilst some of the circumstances of the accident can be established by examination of the vehicles involved, the road and other nearby objection other circumstances are established by witness reports which may conflict. Accordingly, some drivers now equip their vehicles with a camera system known as a dash cam. This allows drivers to store images, typically in the form of video, for use as evidence in the event of an accident. Such devices can provide useful evidence after an incident but are not equipped to provide an early external notification of an accident or indication of the severity of the accident. Additionally, as dash cams require the images to be transferred to another device for external transmission this process can prove cumbersome. Where there is a delay in transmission of the images to another party, there can be a suspicion that the images have been tampered with.
It is therefore an object of the present invention to address problems with the 10 prior art.
Summary of the Invention
According to a first aspect of the present invention there is provided a vehicle accident detection and notification device comprising: a camera operable to capture images related to operation of the vehicle; a data store operable to store captured images; an accelerometer operable to detect accelerations of the device and output a signal indicative thereof; and a communication unit operable to exchange data with an external server; an accident module operable in response to the output of the accelerometer to generate an accident notification and to subsequently transmit the accident notification and captured images from an incident period preceding the generation of the accident notification to the external server via the communications unit.
The present invention provides a device capable of automatically detecting an accident and sending a notification to an external server. This allows immediate notification of the relevant authorities or emergency services in the event of an accident. Furthermore, transmission of captured images allows rapid remote assessment of the severity of the accident and the ability for untampered images to be directly received by a trusted party.
The captured images may be still images or may be video images. The device may comprise a microphone. In such embodiments, the microphone may be operable to capture audio recordings from the vehicle or the vehicle interior. In such embodiments, the accident module may operable to transmit the captured audio from the incident period to the external server via the communications unit.

The device may comprise a speed sensing system. The speed sensing system may be a subsystem of the location sensing system or may be an independent sensing system. The accident module may be operable to include data received from the speed sensing system in the accident indication.
The accident module may be operable to determine that an accident has occurred when the detected acceleration exceeds a threshold value. In some embodiments, the threshold value may vary dependent upon the direction of the acceleration. This can enable different acceleration thresholds to be set for accidents involving side impact to front/rear impact.
The incident period may be fixed or may be varied. In particular, the incident period may be varied in response to vehicle speed or vehicle acceleration at or immediately preceding the time at which the accident notification is generated. This can enable the incident period to be extended for certain categories of accident, for instance high speed impacts.
In some embodiments, the incident period may extend beyond the generation of 5 the accident notification. This can enable images detailing the evolution of the accident and its immediate aftermath to be assessed. This can provide additional information on the severity of the accident as well as the key circumstances of the accident.
The device may comprise an accident classification engine. The accident classification engine may be operable in response to the output of the speed sensing system and/or the accelerometer to classify the accident and issue a classification indication. In this manner different types of accident may be identified such as high speed or low speed incidents, side impacts, front/rear impacts, spins, rolls, slides or the like. The classification indication may be included in the accident notification. In some embodiments, the incident period may be varied in response to the classification indication.
The device may comprise a user interface. When an accident notification is generated, it may be output to the user interface. The accident module may be operable in response to inputs via the user interface to cancel an accident notification. If the inputs are received before the accident notification has been sent by the communication 20 unit, the sending of the accident notification to the remote server may be cancelled. If the inputs are received after the accident notification has been sent by the communication unit, the accident module may be operable to cause the communication unit to send a cancel notification to the remote server in respect of the accident notification.
The user interface may be operable to enable entry of additional accident details.
Such details may include, but are not limited to: the names and/or contact details of 5 persons involved in or witnesses to the accident, insurance details of persons involved in the accident, details of vehicles involved in the accident, captured images of the accident scene or the like.
In some embodiments, the accident module may be operable in response to the user interface to generate an accident notification. In such embodiments, interface generated accident notifications are transmitted to the external server along with captured images from an incident period preceding the generation of the accident notification and any other related data via the communications unit. This can enable to user to directly ensure notification of and the preservation of data relating to an accident that fails to trigger an automatic notification alert. This might occur typically in low speed accidents or relatively minor collisions.
The device may incorporate or be provided with a support fitting. The support fitting may be operable to enable the device to be mounted in a desired location within the vehicle and at a desired orientation within the vehicle. Preferably, the device is mounted on the dashboard of the vehicle.
The camera is preferably positioned so as to enable the capture of images equivalent to the vehicle driver’s point of view in normal driving operation. The device may comprise multiple cameras. If so, a primary camera is preferably positioned so as to enable the capture of images equivalent to the vehicle driver’s point of view in normal driving operation. In such cases a secondary camera may be positioned to capture images of the driver.
The device may comprise a smartphone or the like. In such embodiments, the accident module may be implemented by a software application running on the device. 5 Implementation on a smartphone enables easy adoption of the invention. Beneficially it also enables identification of the smartphone owner as being involved in an accident rather than any individual that has access to the vehicle.
The vehicle may be any road vehicle. Preferably, the vehicle is a car, van, lorry or the like.
According to a second aspect of the present invention, there is provided a vehicle accident detection and notification system comprising: one or more vehicle accident detection and notification devices according to the first aspect of the present invention, each vehicle accident detection and notification device fitted to a vehicle;
and a server operable to receive accident notifications and captured images from an incident period preceding the accident notification.
The system of the second aspect of the present invention may incorporate any or all features of the first aspect of the present invention, as desired or as appropriate.
The server may comprise a data store. The data store may be operable to store details of all received accident notifications and all received captured images in the data store. In the event that any further data is received relating to an accident notification, the server may be operable to store this other data in the data store.
The server may comprise an accident classification engine. The accident classification engine may be operable in response to the output of the speed sensing system and/or the accelerometer to classify the accident and issue a classification indication. In this manner different types of accident may be identified such as high speed or low speed incidents, side impacts, front/rear impacts, spins, rolls, slides or the like.
The server may be operable to distribute stored data to one or more additional systems. The systems may include specified user accounts or devices, emergency services, vehicle repair or recovery services, vehicle manufacturers, insurance companies, legal representatives and the like.

Detailed Description of the Invention
In order that the invention may be more clearly understood an embodiment thereof will now be described, by way of example only, with reference to the accompanying drawings, of which:
Figure 1 is a schematic illustration of a system according to the present invention;
and
Figure 2 is a schematic illustration on an embodiment of a device according to the present invention.
Turning to figure 1, a vehicle 1 is fitted with a vehicle accident detection and notification device 10 according to the present invention. In the event that device 10 determines that the vehicle has been involved in an accident, the device 10 will transmit an accident notification to a server 20 via a suitable communication network 2.
Typically, the communication network might be a cellular telephone or data network. Alongside the accident notification, the device 10 also transmits captured images from an incident period preceding the accident.
Upon receipt of the notification and images, the server 20 is operable to store 5 the notification and images in a data store 21 for future access by authorised users. Typically, the notification and images may be accessed by the users or other persons or organisations authorised by the users such as emergency services, vehicle repair or recovery services, vehicle manufacturers, insurance companies, legal representatives and the like. In some embodiments the server may also output the notifications and captured images to an operator interface 22 for review. This can enable a human operator to determine whether any assistance from the emergency services is required.
Turning now to figure 2, one possible embodiment of a suitable device 10 is shown. Typically, the device 10 will be a smartphone adapted to be provided with an accident module 11 operable to control the operation of integral smartphone systems.
The accident module 11 may be implemented as a software application running on the smartphone or as a hardware accessory incorporating suitable processing means.
In use, the device 10 is mounted on the dashboard of vehicle 1, positioned so as to be able to capture images, preferably video images, substantially similar to the vehicle prover’s point of view. For capturing images, the device 10 is provided with a 20 camera 12. Images captured by the camera are stored in a data store 14. In addition the device is provided with an accelerometer 13 operable to detect acceleration of the device 10 and hence acceleration of the vehicle 1 and output a signal indicative thereof.
The accident module 11 is operable to monitor the output of the accelerometer
13. If the detected acceleration exceeds a threshold value, the accident module 11 can determine that an accident has occurred. In response to determining that an accident may have occurred, the accident module is operable to generate an accident notification and to subsequently transmit the accident notification to the server 20 by use of a communication unit 15 provided in the device and suitable for accessing communications network 2. In addition to the accident notification, captured images from an incident period preceding the generation of the accident notification are retrieved from the data store 14 by the accident module 11 and transmitted to the server
20 using communications unit 15.
In instances where there is insufficient data bandwidth for the transmission of images, the accident notification may be transmitted in another format, such as an SMS message or the like. The captured images can subsequently be transmitted once the communications unit 15 is able to connect to a suitable communication network.
In preferred embodiments, the incident period may be extended for some time after the generation of the accident notification. This can allow images to be captured of the ongoing accident and the aftermath of the accident. In one example, the incident period may extend for 15 seconds preceding the generation of the accident notification and 5 seconds after the generation of the accident notification.
In some embodiments, the device 10 may also be provided with a microphone which is operable to capture audio recordings and store the captured audio in the data store 14. The captured audio from the incident period may also be retrieved from the data store 14 by the accident module 11 and transmitted to the server 20 using communications unit 15.
In some embodiments, the device may be provided with a location sensing system 17 operable to calculate the device location. The output of the location sensing 5 system 17 at the time of or during the incident period preceding the generation an accident notification may be included in the accident notification.
In some embodiments, the device 10 may incorporate a speed sensing system 18, which may be a subsystem of the location sensing system. The output of the speed sensing system 18 at the time of or during the incident period preceding the generation an accident notification may be included in the accident notification.
In some embodiments, the device 10 is provided with a user interface 19. In such embodiments, the accident module 11 may be operable to output an accident indication on the user interface 19. In response, the user may be able to utilise the user interface to make a cancel input. This can enable the cancellation of the accident notification in the event of a false alarm. Additionally or alternatively, the user interface may be operable to enable user input of additional details relating to the accident. Typically, this would enable the user to input specific details of the accident into the device 10 via the user interface 19 for onward transmission to the server 20 for storage.
The user may additionally utilise the interface to capture, images (still or video) and audio from the accident aftermath for transmission to and storage by the server 20.
In such embodiments it is also possible for user input via the user interface to cause the accident module to generate an accident notification and transmit the notification, along with images and any other associated data to the server 20 via the communication unit 15. This allows a user to report and preserve data relating to accidents that were not severe enough to be detected automatically.
In further embodiments, it is possible for the device or the server to comprise an accident classification engine (not shown). The accident classification engine is 5 operable to receive the output of the speed sensing system 18 and/or the accelerometer to classify the accident and issue a classification indication. In this manner different types of accident may be identified such as high speed or low speed incidents, side impacts, front/rear impacts, spins, rolls, slides or the like. This can enable the incident period to be varied as required in response to the classification of the accident. It can also enable the automatic output of accident notifications and images for review on operator interface 22 for the most severe accident classifications.
The above embodiment is described by way of example only. Many variations are possible without departing from the scope of the invention as defined in the appended claims.
