Definitions

  • This invention relates to an improved navigation device and method.
  • Portable navigation devices including GPS (Global Positioning System) signal reception and processing means are well known and are widely employed as in-car navigation systems.
  • GPS Global Positioning System
  • modern PNDs comprise: a processor, memory (at least one of volatile and non-volatile, and commonly both),
  • a GPS antenna by which satellite-broadcast signals including location data can be received and subsequently processed to determine a current location of the device
  • electronic gyroscopes and accelerometers which produce signals capable of being processed to determine the current angular and linear acceleration, and in turn, and in conjunction with location information derived from the GPS signal, velocity and relative displacement of the device and thus the vehicle in which it is mounted
  • input and output means examples including a visual display (which may be touch sensitive to allow for user input), one or more physical buttons to control on/off operation or other features of the device, a speaker for audible output, optionally one or more physical connectors by means of which power and optionally one or more data signals can be transmitted to and received from the device, and
  • the PND is manifested primarily in its ability to determine a route between a start or current location and a destination, which can be input by a user of the computing device, by any of a wide variety of different methods, for example by postcode, street name and number, and previously stored well known, favourite or recently visited destinations.
  • the PND is enabled by software for computing a "best” or "optimum” route between the start and destination address locations from the map data. A "best" or "optimum” route is determined on the basis of predetermined criteria and need not necessarily be the fastest or shortest route.
  • the selection of the route along which to guide the driver can be very sophisticated, and the selected route may take into account existing, predicted and dynamically and/or wirelessly received traffic and road information, historical information about road speeds, and the driver's own preferences for the factors determining road choice.
  • the device may continually monitor road and traffic conditions, and offer to or choose to change the route over which the remainder of the journey is to be made due to changed conditions.
  • Real time traffic monitoring systems based on various technologies (e.g. mobile phone calls, fixed cameras, GPS fleet tracking) are being used to identify traffic delays and to feed the information into notification systems.
  • the navigation device may typically be mounted on the dashboard of a vehicle, but may also be formed as part of an on-board computer of the vehicle or car radio.
  • the navigation device may also be (part of) a hand-held system, such as a PDA (Personal Navigation Device) a media player, a mobile phone or the like, and in these cases, the normal functionality of the hand-held system is extended by means of the installation of software on the device to perform both route calculation and navigation along a calculated route.
  • a PDA Personal Navigation Device
  • the user interacts with the navigation device to select the desired calculated route, optionally from a list of proposed routes.
  • the user may intervene in, or guide the route selection process, for example by specifying that certain routes, roads, locations or criteria are to be avoided or are mandatory for a particular journey.
  • the route calculation aspect of the PND forms one primary function provided, and the navigation along such a route is another primary function.
  • the PND provides visual and/or audible instructions to guide the user along a chosen route to the end of that route, that is the desired destination. It is usual for PNDs to display map information on-screen during the navigation, such information regularly being updated on-screen so that the map information displayed is representative of the current location of the device, and thus of the user or user's vehicle if the device is being used for in-car navigation.
  • An icon displayed on-screen typically denotes the current device location, and is centred with the map information of current and surrounding roads and other map features being also displayed. Additionally, navigation information may be displayed, optionally in a status bar above, below or to one side of the displayed map information, examples of navigation information including the distance to the next deviation from the current road required to be taken by the user, the nature of that deviation possibly being represented by a further icon suggestive of the particular type of deviation, for example a left or right turn.
  • the navigation function also determines the content, duration and timing of audible instructions by means of which the user can be guided along the route. As can be appreciated a simple instruction such as "turn left in 100 m" requires significant processing and analysis.
  • user interaction with the device may be by a touch screen, or additionally or alternately by steering column mounted remote control, by voice activation or by any other suitable method.
  • a further important function provided by the device is automatic route re-calculation in the event that
  • a route to be calculated with user defined criteria; for example, the user may prefer a scenic route to be calculated by the device, or may wish to avoid any roads on which traffic congestion is likely, expected or currently prevailing.
  • the device software would then calculate various routes and weigh more favourably those that include along their route the highest number of points of interest (known as POIs) tagged as being for example of scenic beauty, or, using stored information indicative of prevailing traffic conditions on particular roads, order the calculated routes in terms of a level of likely congestion or delay on account thereof.
  • POIs points of interest
  • Other POI-based and taffic information-based route calculation and navigation criteria are also possible.
  • route calculation and navigation functions are fundamental to the overall utility of PNDs, it is possible to use the device purely for information display, or "free- driving", in which only map information relevant to the current device location is displayed, and in which no route has been calculated and no navigation is currently being performed by the device. Such a mode of operation is often applicable when the user already knows the route along which it is desired to travel and does not require navigation assistance.
  • More modern PNDs are being provided not only with the essential GPS antenna capable of receiving satellite signals, but also with a secondary mobile telecommunications antenna which effectively enables the device to become part of a mobile telecommunications network.
  • the device may additionally be provided with an integrated or removable subscriber identity module (SIM) card on which are provided various data which are required to identify the device to the network and to encode and decode signals appropriate to that network to allow communication thereover.
  • SIM subscriber identity module
  • PNDs and navigation systems with a further short-range wireless communication means, such as a Bluetooth® or Wi-Fi antenna which facilitates the pairing of the device with a similarly enabled other device, most commonly a mobile telecommunications handset.
  • a further short-range wireless communication means such as a Bluetooth® or Wi-Fi antenna which facilitates the pairing of the device with a similarly enabled other device, most commonly a mobile telecommunications handset.
  • Both of these technologies effectively permit a previously passive device, that is one which merely provides in-car navigation and route guidance functions based on the continuous and repeated determination of the current position of the device from the received GPS signals, to become an active device which is capable of transmitting information via a wider telecommunications network back to a centralized data processing service.
  • US6253151 describes a feature whereby an end user of a navigation system that uses geographic data can easily report perceived errors or inaccuracies in the geographic data or other problems such as poor quality route calculation or guidance wirelessly.
  • the end user uses a user interface of the navigation system to indicate the perceived error, inaccuracy, or other problem.
  • the navigation system includes a report program that operates in response to the end user's indication.
  • the report program collects information indicating the error, inaccuracy, or other problem and sends a report including the collected information to a geographic database developer.
  • the geographic database developer can use the information in the report to update a geographic database.
  • the above system however is more concerned with ensuring that a centralized geographical or map database of a map data provider is as current and accurate as possible, as opposed to the provision of non-map related data, for example transient phenomena such as road works, temporary diversions and road closures, traffic congestion, accidents and other transient incidents or events which affect traffic flow and movement but do not ultimately represent a defect in the underlying map data.
  • transient phenomena such as road works, temporary diversions and road closures, traffic congestion, accidents and other transient incidents or events which affect traffic flow and movement but do not ultimately represent a defect in the underlying map data.
  • a method of operating a PND or navigation system including the steps of providing a means by which a specific location or location range, being identifiable with reference to map data locally stored in the device or system and optionally being or including the current location, can be at least temporarily stored in memory, and characterized in that the method includes the further steps of presenting to the user a plurality of user-selectable options each indicative of a plurality of transient phenomena, the selection of one or more of which results in the association of that or those phenomena with the identified location or range and the storage of such together therewith as primary information, and further characterized in that the primary information is subsequently transmitted to a remote device.
  • the primary information is subsequently transmitted wirelessly, although this invention encompasses the embodiment where the user of the device or system is afforded the opportunity of associating particular transient phenomena with a particular location or range at the time such phenomena occur, and storing the primary information in the device or system for later transmission to a remote device by means of a physical connection, for example to a remote PC or appropriate or suitable device by means of a USB or other cable type which connects the device or system to said PC or appropriate or suitable device.

  • the secondary information is in at least one of alphanumeric and digitized audio form, the former being capable of being entered by the user through a touch sensitive screen of the device, and the latter being recorded through microphone means provided as part of the device or system.
  • the method includes the step of presenting an option to enter an audio recording mode, selection of which causes the device or system to activate the microphone and immediately commence the digitization of the audio signals received therefrom, such being streamingly stored in a digital audio file.

  • the transient phenomena are one or more of traffic congestion characteristics and/or details, accidents and details thereof, thoroughfare diversions, closures and restrictions including road works and repairs, current local weather conditions, and extraordinary vehicle identifications such those being particularly wide, heavy or slow, among others.

  • the PND or navigation system may not be provided with a mobile telecommunications antenna, such being provided by a local mobile telephone or other device capable of communicating over a mobile telecommunications network.
  • the PND or navigation system may be provided with a short-range wireless antenna by means of which a communication is established with the local mobile device such that the primary and secondary information is firstly transmitted to the local mobile device for subsequent transmission over the wireless telecommunications network thereby.
  • the invention provides a means for real-time or quasi- real-time reporting of transient phenomena to a remote device or system for collation, validation, and subsequent return delivery to other appropriately enabled devices, most preferably by means of a wireless telecommunications network, said appropriately enabled devices effectively forming nodes within said network.
  • the facility for reporting transient phenomena provides a legally more acceptable means of communicating transient traffic, accident and thoroughfare phenomena than using a mobile telephone while driving, which in many countries is now illegal unless the vehicle has been fitted with a hands-free system.

  • the GPS system is implemented when a device, specially equipped to receive GPS data, begins scanning radio frequencies for GPS satellite signals. Upon receiving a radio signal from a GPS satellite, the device determines the precise location of that satellite via one of a plurality of different conventional methods. The device will continue scanning, in most instances, for signals until it has acquired at least three different satellite signals (noting that position is not normally, but can be determined, with only two signals using other triangulation techniques). Implementing geometric triangulation, the receiver utilizes the three known positions to determine its own two-dimensional position relative to the satellites. This can be done in a known manner. Additionally, acquiring a fourth satellite signal will allow the receiving device to calculate its three dimensional position by the same geometrical calculation in a known manner. The position and velocity data can be updated in real time on a continuous basis by an unlimited number of users.

  • screenshot 500 the device is displaying map information 502 and a current location indicator 504. Additionally, a user selectable icon 506 is displayed. This is optional, and this icon may form part of an underlying menu structure composed of a variety of different icons which is accessed by merely toching the display screen during map information display, but in any event, the device provides some means whereby a user can provide an indication to the device that he wishes to report an incident or transient phenomenon of some kind.
  • the icon 506 relates to the reporting of a traffic incident. By selecting this on-screen icon, as indicated at 508 the device is caused to enter a traffic reporting mode.
  • map information 502 and current location indicator 504 continue to be displayed, but an alternate, optionally user-selectable icon 512 is displayed, indicating to the user that the device is in a traffic incident reporting mode.
  • the vehicle's current speed (as measured by the device) is compared to the expected traffic speed of the road network along which the device is currently travelling. This may additionally be determined by the device from a comparison of the current geographical device location and the underlying map data stored in the device memory. If the vehicle's current speed is lower than an expected traffic speed value stored in the device memory for the particular type of road concerned (alternatively this data may be derived from the map data speed limit information for the current road), the location of the vehicle and the current vehicle speed are transmitted, ideally by means of a mobile telecommunications network of which the device forms a part as a result of its being provided with a suitable antenna and an appropriate subscriber identity module, to a remote data processing server. If the vehicle's current speed is not lower than the expected traffic speed, the device exits "Traffic Incident Reporting Mode".
  • the device While in "Traffic Incident Reporting Mode", the device ideally wirelessly transmits its current speed and position every 30 seconds. This continues until one of the following conditions is met:
  • the vehicle speed increases to the expected traffic speed for the road for at least 30 seconds.
  • the user reaches their destination (if a route is planned).
  • the device automatically exits the "Traffic Incident Reporting Mode” and the "Reporting Traffic Incident” icon 512 is replaced with the "Report Traffic Incident” icon 506.
  • the "Reporting Traffic Incident" icon 512 may optionally be user selectable to display further, more specific icons indicative of particular types of traffic-related, transient, local incident which might be usefully reported to the central processing centre for subsequent re-transmission to other users in the installed user-base of devices.

  • the device would not be caused to enter an incident reporting mode until one of the icons 516, 518, 520, 522, 524, 526 is chosen so that the particular type of transient incident, event or phenomena is suitably identified. Thereafter, the device may be caused to return to the screenshot of 510.
  • the invention may also provide a feature of automatic traffic incident reporting. Accordingly, an option will be provided as part of the device software which when selected or enabled, causes the device to periodically compare the current device speed with the expected speed of travel for the particular road network element or segment along which the device is, at the moment of comparison, traveling.
  • the period of comparison may also be adjustable, or may be pre-set, for example at 10s intervals. If the automatic incident reporting feature is enabled, the comparison should occur regardless of whether the device is operating in a free-driving or navigation mode, that is when a route has been planned and the device is providing navigation of such route to a user.
  • the automatic traffic incident reporting feature may only become “active", after having been enabled, once the speed of the device reaches the expected travel speed of the current road network element. This is done so that incidents are not reported when the device is stationary at the beginning of a journey or immediately after having been switched on, otherwise the feature can be active as soon as the device begins to move, and spurious traffic incident data would be reported.
  • the device shall upload some form of road element identification together with the current speed to a remote back-end processing, validation, and/or collation facility, ideally using a wireless data connection (e.g. GPRS, WiFi, 3G), as previously described.

  • - Traffic incidents shall be assigned a validity period, a default validity period being for example 30 minutes; optionally the validity period of an incident may be set according to the incident type (if one is specified) or by analysis of the incident severity (i.e. 30% speed reduction incidents have shorter validity than 80% speed reductions).
  • traffic incident reports shall be delivered to the installed user base of devices as part of an overall traffic incident reporting service (optionally provided on a subscription basis to device owners), including identification of traffic incidents and general traffic flow information from other , e.g. governmental and/or commercial, sources.
