Abstract

A vehicle’s location is determined S112 using a receiver and stored mapping data, and a third party’s location is determined S106 using the mapping data and a received signal S104. A destination, other than the third party’s location, is determined S110 depending on a known location that is stored in memory. A route to that destination is determined S114 and indicated S116. The received signal may be an SMS message or email comprising GNSS coordinates. The known location may be a car park or parking space. Several candidate destinations may be ranked prior to selection. Selection criteria for the destination may include availability of parking spaces, proximity to the third party, pedestrian or wheelchair accessibility, vehicle type or size, or prevailing environmental conditions such as weather. An estimated time of arrival (ETA) may be determined and transmitted, and a message may be transmitted to a third party upon arrival.

Description

VEHICLE NAVIGATION

TECHNICAL FIELD

The present disclosure relates to a vehicle navigation apparatus. Particularly, but not exclusively, the disclosure relates to a vehicle navigation apparatus for enabling navigation of a vehicle to a destination determined in dependence on a signal from a third party user. Aspects of the invention relate to a vehicle navigation apparatus, to a vehicle, to a method, to a controller, to a computer program product and to a computer readable medium.

BACKGROUND

There is a desire to provide improved means of navigating a vehicle. In particular, if a user of a vehicle wishes to go somewhere that is unmapped, known systems are not capable of accurately and efficiently navigating the user of a vehicle to the unmapped location. Attempts to navigate to the unmapped location may not be possible, or may result in multiple search iterations of a map.

Known systems for navigating a vehicle typically involve a user selecting a destination in a device and the device showing a route to the destination. If the destination is not mapped, this is not possible. Accordingly, a user of a vehicle may be able to reach a general area, but not an exact destination. A significant amount of time may be spent searching for the exact location and the user of the vehicle may become distracted and/or frustrated by the inaccuracy and inefficiency of such known methods in particular scenarios.

It is an aim of the present invention to address the above-described disadvantages associated with the prior art.

SUMMARY OF THE INVENTION

Aspects and embodiments of the invention provide a vehicle navigation apparatus, to a vehicle, to a method, to a controller, to a computer program product and to a computer readable medium as claimed in the appended claims.

According to an aspect of the invention, there is provided a vehicle navigation apparatus comprising: receiving means; processing means; display means; and storage means having mapping data; wherein: the vehicle navigation apparatus is configured, by the processing means: to determine a first location of a vehicle to which the vehicle navigation apparatus is connectable, in dependence of a first signal receivable by the receiver and the mapping data stored in the storage means; to determine a third party's location in dependence on a second signal receivable by the receiving means and the mapping data stored in the storage means; to determine a destination in dependence on at least one known location stored in the mapping data, wherein the determined destination is different from the third party's location; to determine a route from the first location to the determined destination; and to indicate the route from the first location to the determined destination by the display means, thereby to enable vehicle navigation from the first location to the determined destination.

Advantageously, the vehicle navigation apparatus enables navigation to a suitable destination that is not the location of the user sending their location data. In situations where the location of a third party user is not mapped, or not suitable for parking, the vehicle navigation apparatus guides a user of a vehicle to the most appropriate location. Beneficially, a user is navigated to the best destination for the user, without having to waste time determining exactly where a third party is and where the nearest parking place to the third party is.

Optionally, the second signal comprises a location identifier and/or longitude data and latitude data. Optionally, the longitude and latitude data is Global Navigation Satellite System (GNSS) data.

This may be particularly useful for disabled users, parents with small children requiring pushchairs or strollers or where the user wishes to load or unload heavy or bulky items to/from the vehicle.

Optionally, if a determined destination is identified amongst several determined destination options, for example, if a parking space is identified amongst several parking space options, then the controller may order the determined destinations in order of convenience or accessibility for a pedestrian or wheelchair user, as may be appropriate.

Optionally, the determined destination comprises the most accessible known location with respect to the third party's location, where the level of accessibility may be chosen from a list options comprising: pedestrian; pedestrian with young children, or wheelchair user. In some circumstances it is preferable to select the parking space that is the most accessible for a pedestrian to make their way to the third party’s location on foot, or with a pushchair or stroller, or by wheelchair.

Beneficially, the determined destination may preferably be chosen based on the shortest duration walk or most convenient wheelchair journey between the parked vehicle and the location of the third party. This may be important if the nearest parking space to the third party is on the wrong side of a river, major intersection or highway, where the journey by foot may not be convenient or practical.

Additionally or alternatively, the vehicle navigation apparatus comprises means to receive a signal indicative of a status of the vehicle, that status being either that the vehicle is not towing a trailer, or that the vehicle is towing a trailer. In this example, the determined destination comprises the location of a parking space that is the nearest parking space to the third party's location that is large enough to accommodate both the vehicle and the trailer. Additionally, or alternatively, the vehicle navigation apparatus comprises means to receive a signal indicative of any addition or alteration to a vehicle that may alter parking requirements of the vehicle, and means to determine a destination in dependence on the signal indicative of any addition or alteration to the vehicle.

Advantageously, the vehicle navigation apparatus is configured to react to changes in the physical requirements of a vehicle whilst still providing the most appropriate determined destination for a user of a vehicle to meet with a third party.

Beneficially, if conditions change, the best route to the destination is selected.

Optionally, the destination is determined in dependence on at least one of a vehicle type or vehicle size of a vehicle to which the vehicle navigation apparatus is connectable.

Advantageously, the destination is determined as the best destination for the vehicle to which the vehicle navigation apparatus is connectable.

Optionally, the destination is determined based on prevailing environmental conditions.

Beneficially, the prevailing environmental conditions are used to determine the most appropriate route to the destination, meaning that the navigation is dynamic and reactive to potential changes.

DETAILED DESCRIPTION

Figure 1 is a schematic of a vehicle navigation apparatus 10 according to an embodiment of the invention. There is shown a controller 12, a processor 14 and a memory 16. The controller 12 is in communication with a receiver 20 via communication path 19. The controller 12 is also in communication with a transmitter 22 via communication path 21. The controller 12 is also in communication with an output 18 via communication path 17. The output 18 is a display. Alternatively, or additionally, the output 18 is an audio output. Alternatively, or additionally, the output 18 is configured to provide audio and visual outputs.

In an embodiment the controller 12 comprises a memory 16. In a further embodiment, the controller 12 comprises a memory 16, a processor 14 and/or any other required component to implement the functionality described herein. Alternatively, or additionally the memory 16 is external to the controller 12 and the controller 12 comprises a processor 14.

Alternatively, or additionally, the receiver 20 and the transmitter 22 are combined in a single integrated transceiver. Alternatively, or additionally, the receiver 20, the transmitter 22 and/or a transceiver are integrated into the controller 12.

The vehicle navigation apparatus 10 is associated with a vehicle, such as the vehicle 50 of Figure 4. Additionally, or alternatively, the vehicle navigation apparatus 10 may form part of an infotainment system that is used to coordinate the reception of data from third parties and indicate to a user of a vehicle the route from a current location to a determined destination.

In situations where a third party user wishes to arrange a meeting with the user of a vehicle, but the location of the third party is somewhere that is inaccessible, for example a rocky area that is unsuitable for cars, or a beach, or a pedestrianized area of a town or city, the vehicle navigation apparatus 10 is used to determine the most appropriate place to park a vehicle so that the third party and the user of the vehicle can meet with the least inconvenience for the third party user and/or the user of the vehicle. This is described in more detail below, with reference to Figure 2.

Figure 2 is a flow chart S100 of a method for navigating a vehicle, according to an embodiment of the invention. The method is implemented by a vehicle navigation apparatus, such as the vehicle navigation apparatus 10 described with reference to Figure 1.

The process commences at S102, where the process is initiated by a third party user. A third party user is a user who is at a location and wishes to arrange a meeting with the user of the vehicle. Preferably, in some situations, the third party would meet the user of the vehicle at the third party's location. The third party's location may therefore be the desired location. However, the desired location may not always be readily accessible. The third party user sends data to the vehicle navigation apparatus 10 via a short message service (SMS) message. The data sent by the third party user is received by the receiver 20 of the vehicle navigation apparatus 10 at step S104. The process then moves to step S106, where the data is passed to the controller 12 via the communication path 19 in order to determine the location of the third party user. The process then moves to step S108.

At step S108, following receipt of the data, the vehicle navigation apparatus 10 determines whether the data comprises Global Navigation Satellite System (GNSS) data. If the data does not comprise positioning data (such as GNSS data) data, the process moves to step S118, where it ends. As described below, the principles are applicable to other forms of data that determines the position of an object, e.g., other satellite based positioning, Wi-Fi based positioning etc. If the data does comprise GNSS data, the process moves to step S110.

At step S110, the controller 12 determines a destination. The destination is determined based on a comparison of mapping data retrieved from the memory 16 with the GNSS data received at the vehicle navigation apparatus 10. The controller 12 determines a destination from known destinations stored in the memory 16. The determined destination is the closest destination of the known destinations to the location of the third party (which may be the closest destination of the known destinations to the desired location). In an example, when the controller 12 determines that the location of the third party user is inaccessible to the vehicle, e.g., if the third party user is on a beach, or in a field, where vehicular access is not possible, or restricted, the controller determines the destination as the closest possible location to the desired location that the vehicle has access to and can park at. For example, the controller 12 determines the nearest parking bay with vehicular access to the third party user's location. Alternatively, or additionally, the controller determines the destination as the nearest parking location with vehicular access in dependence on one or more parameters of the vehicle, for example the height, weight or width of the vehicle, or required room to access the vehicle. Alternatively, or additionally, the controller 12 determines the destination as a location with vehicular access in dependence one or more conditions, such as prevailing environmental conditions. For example, if the weather permits, a field that is not accessible to a vehicle when wet, may be accessible to a vehicle when dry. Alternatively, or additionally, the controller 12 determines the destination in dependence on data stored by a third party device, such as a server. Alternatively, or additionally, the controller 12 determines a plurality of potential destinations and ranks the plurality of potential destinations in dependence on one or more criteria, such as pedestrian accessibility, or wheelchair accessibility. Alternatively, or additionally, the controller determines a plurality of potential destinations that are presented to a user via the display.

The parking location may preferably be chosen based on the shortest duration walk or most convenient wheelchair journey between the parked vehicle and the location of the third party. This is important if the nearest parking space to the third party is on the wrong side of a river, major intersection or highway, where the journey by foot may not be convenient or practical. If such a parking space is identified amongst several parking space options, the controller 12 may order the parking spaces in order of convenience or accessibility for a pedestrian or wheelchair user as may be appropriate. In this way, the most convenient and accessible parking spaces will be ordered at the top of a list presented to the user via the display and the user may choose which parking space or parking area the vehicle should navigate to based on their own preferences or circumstances. This may be particularly useful for disabled users, parents with small children requiring pushchairs or strollers or where the user wishes to load or unload heavy or bulky items to/from the vehicle.

Additionally or alternatively, the vehicle navigation apparatus 10 comprises means to receive a signal indicative of a status of the vehicle, that status being either that the vehicle is not towing a trailer, or that the vehicle is towing a trailer. In this example, the determined destination comprises the location of a parking space that is the nearest parking space to the third party's location that is large enough to accommodate both the vehicle and the trailer. Additionally, or alternatively, the vehicle navigation apparatus 10 comprises means to receive a signal indicative of any addition or alteration to a vehicle that may alter parking requirements of the vehicle, and means to determine a destination in dependence on the signal indicative of any addition or alteration to the vehicle. Advantageously, the vehicle navigation apparatus 10 is configured to react to changes in physical requirements whilst still providing the most appropriate determined destination for a user of a vehicle to meet with a third party.

The process then moves to step S112, where the vehicle location is determined. The vehicle location is determined using GNSS data received by the vehicle navigation apparatus 10 via the receiver 20. The vehicle location may be referred to as a first location. Alternatively, or additionally, the vehicle location is dynamically updated along a route whilst the vehicle is moving, thereby providing a first location of the vehicle, a second location of the vehicle, a third location of the vehicle etc., where the iteration of the vehicle's location is based on subsequent determinations of the vehicle location with respect to the first location of the vehicle.

Once the vehicle location has been determined at step S112 and the destination has been determined at step S110, the vehicle navigation apparatus 10 determines a route from the vehicle location to the determined destination at step S114.

Once the route from the vehicle location to the determined destination has been determined at step S114, the process moves to step S116, where the route is displayed via the communication path 17 to the display 18 of the vehicle navigation apparatus 10.

The process then ends at step S118. Alternatively, or additionally, the route is dynamically updated and indicated to a user of the vehicle navigation apparatus 10, so that, in the event that the route conditions change, a different route is determined and indicated to a user, or a different destination is determined.

Whilst the steps of flow chart S100 are described in a particular order above, alternatively, the steps can be carried out in any appropriate order, such as determining the vehicle location prior to determining the destination as described at steps S112 and S110.

Alternatively, or additionally, the destination is determined based on mapping data retrieved from an external source, such as from a server.

Whilst the SMS message is described above as being received by the receiver 20 of the vehicle navigation apparatus 10, alternatively, or additionally, the SMS message is received at a user device in communication with the receiver 20 of vehicle navigation apparatus 10, such as a mobile device connected by Bluetooth, Wi-Fi or other suitable means to the vehicle navigation apparatus 10.

Whilst the GNSS data described above is described as being included in an SMS message, alternatively, or additionally, the GNSS data may be received in an e-mail, or by an application, or in any form that enables a third party to communicate the GNSS data to the vehicle navigation apparatus 10. Whilst GNSS data is described as the mechanism by which the location of the third party is transmitted to the vehicle navigation apparatus 10, alternatively, or additionally, any data indicating the latitude and longitude of the third party may be used to transmit the location of the third party to the vehicle navigation apparatus 10. Other mechanisms can be used, such as information from Wi-Fi, or any satellite-based positional identification mechanisms.

Whilst one receiver 20 is described with respect to Figure 1, alternatively or additionally, there may be any number of receivers that form a part of the vehicle navigation apparatus 10. Whilst one transmitter 22 is described with respect to Figure 1, alternatively or additionally, there may be any number of transmitters that form a part of the vehicle navigation apparatus 10.

Whilst the determined destination is described above as being the closest destination of the known destinations to the location of the third party, alternatively, or additionally, the determined destination is determined based on a property of the vehicle, such as the width, length, weight or height of the vehicle, the type of vehicle, the requirements for access to the vehicle by one or more users of the vehicle, or other considerations. For example, alternatively, or additionally, the determined destination is based upon the prevailing environmental conditions.

Whilst at step S116, the route from the determined location of the vehicle to the determined destination is shown via the display 18, alternatively, or additionally, the route is indicated to a user of the vehicle navigation apparatus 10 by any suitable method, such as through audio signals.

Alternatively, or additionally, the vehicle navigation apparatus 10 is configured to determine an estimated arrival time at the determined destination. The estimated arrival time at the determined destination is communicated to a user of the vehicle via the display 18. Alternatively, or additionally, the estimated arrival time is communicated to the third party user via the transmitter 22 that is in communication with the controller 12 via a communication path 21, as described above with reference to Figure 1.

Alternatively, or additionally, the vehicle navigation apparatus is configured automatically to transmit a message to a third party upon arrival at the determined destination. The message may be transmitted via the transmitter 22 that is in communication with the controller 12 via a communication path 21, as described above with reference to Figure 1.

Whilst Figure 2 is described with reference to a single process for determining a route from the first location to a determined destination, alternatively, or additionally, the vehicle navigation apparatus 10 is configured periodically to determine the first location (which may optionally be described as a second location, third location etc., depending on the number of iterations made in calculating the route from the current location to a determined destination), thereby to enable dynamic navigation from the first location to the determined destination.

Alternatively, or additionally, the first location, which may be the current location, is communicated to the third party user, thereby to keep the third party user informed as to the progress of the vehicle to which the vehicle navigation apparatus 10 is connectable. The current location of the vehicle navigation apparatus may be automatically communicated to the third party, or communicated to the third party upon a user's request. A user's request may be initiated by the user of the vehicle, or by the third party. Beneficially, the progress of the vehicle is dynamically updated to the third party, as required. The vehicle navigation apparatus 10 can communicate with the third party via signals transmitted by the transmitter 22 of the vehicle navigation apparatus 10.

Figure 3 shows a schematic of elements of a controller 30. The elements of the controller 30 are elements of a controller, such as the controller 12 described with reference to Figure 1 above.

The elements include a SMS module 32, an e-mail module 34 and a custom Application module 36. Each of the SMS module 32, the e-mail module 34 and the custom Application module 36 are configured to receive data, such as from a third party, as described above with reference to Figures 1 and 2. The SMS module 32 is configured to receive SMS modules when a mobile device is connected to an infotainment system, which the vehicle navigation apparatus 10 may form part of. The e-mail module 34 is configured to receive e-mail when an infotainment system, which the vehicle navigation apparatus 10 may form part of, is connected to Wi-Fi. Alternatively, or additionally, the infotainment system uses other means of wireless communication, such as cellular communication, 4G, etc.. The custom Application module 36 is configured to receive input data as part of an infotainment system, which the vehicle navigation apparatus 10 may form part of.

The SMS module 32, the e-mail module 34 and the custom Application module 36 are each configured to pass any data received via a communication path 37 to a GNSS decision module 38. The GNSS decision module 38 is configured to determine whether or not the data passed from one or more of the SMS module 32, the e-mail module 34 and the custom Application module 36 to the GNSS decision module 38 comprises GNSS data. If the data comprises GNSS data, the GNSS data is sent to the GNSS parser 40 via a communication path 39. If the data does not comprise GNSS data, no action is taken.

The GNSS parser 40 is configured to parse an SMS message received at the SMS module 32, or an e-mail received at the e-mail module 34 or data received at the custom Application module 38 in order to determine location identifiers or latitudes and longitudes. The GNSS parser 40 is configured to send the location identifiers and/or latitude data and longitude data to a navigation module 42 via a communications path 41. The navigation module 42 is configured to perform functions such as, but not limited to: setting a destination as parsed by the GNSS parser, updating a determined destination based on the nearest parking space for the parsed data, sending an estimated time from the starting point to a third party, sending one or more messages to a third party indicative of the progress of a vehicle along a route from a first location to a determined destination.

Figure 4 is a schematic of a vehicle 50 comprising a vehicle navigation apparatus 10. The vehicle navigation apparatus 10 is in communication with a mobile device 60 of a third party via a communication path 59. The vehicle navigation apparatus 10 is in communication with a server 70 via a communication path 69. The vehicle navigation apparatus 10 may communicate with the mobile device 60 and/or the server 70 via a receiver and transmitter, such as the receiver 20 and the transmitter 22 described with respect to Figure 2. The server 70 has a processor 72 and a memory 74. The method described above at Figure 2 may be implemented in a vehicle, such as the vehicle 50 of Figure 4. A third party user may transmit details regarding their location to the vehicle navigation apparatus 10 such as by mobile device 60 over the communication path 59 between the mobile device 60 and the vehicle navigation apparatus 10. The server 70 is in communication with the vehicle navigation apparatus 10, thereby enabling the vehicle navigation apparatus 10 to be updated with relevant stored information that enables the vehicle navigation apparatus to perform the method described above with respect to Figures 1 to 3.

Whilst the apparatus and methods described herein are described as being implemented in a car, the skilled person understands that the principles and features are applicable to other forms of vehicle.

Advantageously, the apparatus described herein enables a user of a vehicle to meet a third party user who is located at somewhere that is inaccessible or unmapped. For example, beneficially, if a third party user is on a beach, the vehicle navigation apparatus is used to navigate the user of the vehicle to the nearest and/or most appropriate parking location for the vehicle. The user of the vehicle and the third party are then able to meet more conveniently. Further, both parties are able to track the process of navigation with increased efficiency and a reduction in time determining where to go when the location of the third party user is somewhere unmapped/inaccessible.
