Preferably, the device also includes: * a battery for powering the device, when the vehicle is switched off, for receiving such a request and * means for charging the battery when the vehicle is switched on.

Whilst it is envisaged that the memory could be removable from the device, the preferred arrangement is for the memory to be permanently installed in the device in the interests of tamper-proofing. At least where a plurality of video data-streams are to recorded from a plurality of cameras via a plurality of video ports, the memory is preferably a solid-state storage-device/drive.

The CWS module can be a conventional OPS module. The device can be provided with its own OPS aerial in the device. However since the dcvicc preferably has a metal case, it preferably has a port for an external OPS aerial.

The control module is preferably adapted to address the data-streams to the memory in packets of less than one minute of video data and preferably of the order of a quarter of a minute, say between ten and twenty seconds of video data. Such short packets are appropriate for vehicle accidents and other emergencies which are api to have a start-to-finish duration of less than a minute. Further, short duration packets can be more readily transmitted in real time.

Normally the telecommunications module will be a GSM or ccli phone module. Preferably, the module will be adapted for transmissions from the device to be in accordance with a mobile or cellular data communication protocol. However, interests of economy of battery life, the device is preferably adapted to receive requests for vehicle data in text or SMS format, whereby the device can retrieve transmission requests with economic battery usage.

In addition to being adapted to transmit vehicle data in response to a remote request, the device is preibrably adapted to transmit vehicle data in response to a local event. l'or this it preferably has a driver request/alarm button. Further it preferably has an accelerometer arranged to detect an unusual vehicle acceleration of the order of that expected in an accident. Not all accidents involve acceleration high enough to trigger airbag release, which normally occurs at óOg acceleration. Preferably transmission is initiated by an acceleration of the order of 20g.

Preferably the device is adapted for voice communication as well as data IC communication, whereby on transmission resulting from a local event, an operator at a remote base station can communicate with a driver of the vehicle to offer assistance and/or record a driver's description of the event which Led to the local event.

In such event, the device is adapted to transmit vehicle video information in real time after or multiplexed with transmission of vehicle video information leading up to the event.

It is envisaged that the device could include a module utilising facial recognition software for identifying the current driver of the vehicle from video data coming from a camera focused on the driver.

S Conveniently these can be installed at the top of the vehicles A and C posts. Other positions and numbers of cameras can be provided.

Preferably the cameras have wide angle lenses, which will normally be fish-eye lenses. I0

All video data can be recorded from all cameras for as long as the recorders memory is not fill, thereafter oldest data can be overwritten with new data, To economise on memory usage, all data for a previous period such as the previous ten minutes continues to be memorised, whilst earlier data is chopped and memorised in IS economic packets.

Preferably additional vehicle data will be memorised, such as vehicle speed, instantaneous acceleration and GPS derived vehicle location. Again vehicle identification is also permanently memorised.

Conveniently the transmission means is a OSM telephone module. Whilst a driver's telephone installed in the car could be used, for reliability a dedicated telephone module and dedicated SIM card is preferably provided in the recorder.

Normally the recorder will be adapted for secure installation out of sight in the vehicle in a posilion that is not readily accessible.

Conveniently the recorder will be programmed to dial up a designated server and transmit an excerpt of the most recent information upto, including and after the accident. After transmission of this information, the further data can be transmitted from earlier before the accident and later after it.

The means for initiating a transmission is typically an accelerometer, such as an airbag initiation accelerometer, hut conveniently set to initiate transmission at a lower level of aeccleration/dcecleralion than airbag initiation. Often accidents occur with acceleration levels below that a which airbags are set to inflate.

Means may be provided for a driver to initiate a transmission.

S

Normally the recorder wi]] be programmed to start recording video information from the cameras as soon as the vehicle's ignition switch is turned on and/or the vehicle's engine is started. Correspondingly it will be programmed to switch off a brief period after the vehicle has stopped and the engine has been stopped. For ear's having automatic engine switch off at traffic lights, an equivalent signal can be used to stop recording, such as opening of the driver's door and locking of the car.

Means can he provided for recording to continue with the car parked as in a IS car park or on a street. Such recording can be discontinuous and may he altered to being continuous in Lhe event of collision of a third party with the vehicle.

A dashboard contro] can he provided for initiating stationary recording.

Additionally or alternatively a remote control can be provided.

A further dashboard aert that transmission is imminent and eontrot to cancel transmission can be provided.

According to a second aspect of the invention there is provided, a method of vehicle data reeordal and transmission, the method consisting in the steps of: * memorising the identity of a vehicle, its location and vehicle video in secuentialIy addressed and retrievable packets of data, * detecting a transmission requirement at the vehicle for a telecommunication module to transmit certain packets of the memorised vehicle data and * retrieving and transmitting the requested packets of the meinorised vehicle data.

Preferably, the step of detecting of a transmission requirement is performed by receiving a request via a telecommunications module at the vehicle to transmit certain packets of the memorised vehicle data.

S Preferably: * the telecommunications module is a OSM or ccli phone module; * module is adapted for transmissions from the device to be in accordance with a mobile or cellular data communication protocol; and * the step of receiving a request is performed by the module polling for an SMS or text message and receiving such request as an SMS or text message.

The step of detecting of a transmission requirement can performed by a vehicle driver making a transmission request by actuating a control in the vehicle.

Alternatively, or in addition, the step of detecting of a transmission requirement is is performed by detection of a g-thxeshold signal from an accelerometer installed in the vehicle.

To help understanding of the invention, two specific embodimcnts thereof will now be described by way of exampie arid with reference to the accompanying drawings, in which: Figure I isa plan view of an accident about to happen between two cars; Figure 2 is block diagram accident data capture apparatus in accordance with the invention; Figure 3 a perspective view of a second vehicle data recordal and transmission device according to the invention; Figure 4 is a block diagram of the device of Figure 3; and Figure 5 isa diagrammatic plan view of the device of Figure 3 installed in a vehicle.

Referring to Figures 1 and 2 of the drawings, Figure 1 shows a first car 1 driving along a mad and about to be run into by a second car 2 driving into the path of the first. mc first car is equipped with wide angle cameras 3,4 (or respcctivc arrays of canicras to provide wide angles a). The cameras arc installed at the top of the car's A and C posts and arranged to see in front of the car, along the driver's side and behind the car. The cameras have fish eye lenses. Typically the A post camera will see the beginning and progress of the accident and the C post camera will see the progress of the accident if the car I turns away from car 2 and is struck in the side with a glancing or heavy impact blow.

11w cameras are connected to a recorder 5 securely installed behind the car's dashboard to be normally inaccessible. The recorder's ECU feeds video data from the cameras to a memory 6. Further inputs are on set up and not shown the car's identity to and the dial up number of a server to receive accident data, a switched live voltage from the ignition switch 7, an engine running signal from the engine 8, a speed signal from the speedometer 9, an acceleration signal from an accelerometer 10 and a UPS unit 11. A dashboard display and switch interface 12 is also provided.

is The recorder is programmed to record video from the cameras at all times that the cnginc of the ear is running, after switching ON of the ignition. Inputs from the speedometer, accelerometer and UPS unit are also memorised.

In event of a high acceleration input, indicating an accident, the recorded data running up to, during and after the accident is transmftted via a OSM telephone module 14 with an aerial 15 and its SIM card 16. The transmission is delayed until the accident has finished in the sense that the car is stationery. Imminence of transmission is indicated on the dashboard unit. An input from the driver can over-ride transmission. Similarly an input can initiate transmission of a dangerous manoeuvre by another driver, which did not cause an accident causing an unusual acceleration such as to initiate transmission automatically.

A further input can cause continued recording alter parking and locking of the car. Such recording could be started remotely by a non-shown remote control unit. 3°

Further a remote initiation of transmission of recorded information appertaining to a particular time and date may the initiated from a secure server.

Turning on to Figures 3 to 5, a vehicle data recorcial and transmission device is housed in a casing 101 fixed behind the dashboard 102 of a goods vehicle I 01 It is a self-contained device, connected only by ports 104. These comprise: Video feeds ports 1041, * A telecomnii.,nication aerial port 1042, * A telephone microphone and speaker port 1043.

* An emergency button port 1044, * A UPS aerial port 1045, * A vehicle power port. 10i6.

The components within t]ie casing are: * A controller 105 connected to the video feeds ports 1041 * A solid state drive memory 106 connected to the controller to receive and store video feeds from the ports 1041. The controller times each video feed to he stored in 15 second data packets, storage starting again every 15 seconds at a new address in the memory; * A UPS U]lit 107 connected to the UPS aerial port 1045 a]ld the controller Ibr storage of position co-ordinates speed and acceleration at the beginning of each data packet period and at intei-vals therethrough if required; * A telecommunications unit! 08 connected to the telephone aerial port 1 042 and the controller J 05 for ti-ansniission of stored data in accordance a received transmission request. to the emergency button port 1044, for initiauon of a transmission in event of an accic.lcnt arid a transmission request initiated by the driver. In addition, the telceoninmnication unit 108 is connected to the telephone ii icrophone and speaker P0J-t 1 043 For telephone conversation with the driver; * An accelerometer 109 is also connected to the telecommunications unit 108 for initiating a data transmission in event of an accident causing vehicle acceleration above a threshold, typically 20g; * An identification circuit 110 is connected to the memory, whereby each transmitted data packet can be pretheed by the identity of the unit, i.e. the vehicle in which it is installed; A charging circuiL 111 and a battei-y 112 is connected to the vehicle power port 1046. The charging circuit charges the battery whilst the vehicle's electrical circuits ate switched on. the battery is connect to the above circuits for powering them.

The vehicle has an internal camera 11 4 arranged in the cab to monitor the identity of the driver and at each corner of the vehicle a camera 115,116,117,118 arranged respectively to record events at its side of the vehicle and front or behind it respectively. The cameras are connected to the video feeds ports 1041 and are identified by having their own IP addresses. Readily reachable by the driver is an emergency button 119 for initiating transmission of video data prior to pressing of the button and continuing real time video data transmission after the event causing the driver to press the button. 1so mounted on the dashboard is a loudspeaker 120 and microphone 121 for conversation with the driver after a driver initiated transmission.

felecominunieaion and GPS aerials 122, 123 are mounted on the roof of the vehicle, Throughout driving o fthe vehicle, detected by Lhe device by the vehicle's electrical system being ON, and indecd when thc vchicle is stopped, the telecommunications unit polls the local mobile/cellular network for messages in SMS/text format for itself. Normally there will be no such message. However there may be such a message to transmit stored or real time vehicle data. Alternative messages may he to enable the controller to configure itself to receive a software update.

ftc order of magnitude of the video streams should he noted as typically 11 Gigibytes per hour. Given that the vehicle cannot be driven 24 hours a day, without driver change at the end of each shift, a currently available 2['errabyte is expected to record vehicle data for 3 or 4 weeks. When the memory is full. new data is written over the oldest data on a roiling basis. Further given that a vehicle, particularly a goods or luìre-paying passenger vehicle, is valuable and unlikely to remain unuscd for a significant period, the battery is sized to provide for message polling and transmission if requested for three weeks.

The invention is not intended to be restricted to the details of the above described embodiment. For instance a status display can be provided, adapted to display messages such as: Recording as normal Transmitting in response to Routine Request About to transmit in response to Emergency Press to CANCEL Emergency Transmission Transmitting in response to Emergency Request Further, the emergency button circuit can be adapted to be made via a remote operation from a portable unit carried by the driver when he is out of the cab of the vehicle.
