Embodiments of the inventive aspects of this disclosure will be best understood with reference to the following detailed description, when read in conjunction with the accompanying drawings, in which:
In accordance with embodiments of the present invention, a system for providing limited-destination navigational guidance to a user when driving a vehicle is disclosed. The system comprises a processor; a memory pre-configured to store location information for a limited number of desired destinations; a user interface coupled to the processor, comprising one or more actuators, each linked to location information for one of the desired destinations; and a network interface. The user interface is configured to provide navigational guidance information, which may be provided acoustically or visually or both. The memory is advantageously pre-configured to store location information for a limited number of destinations before the user even enters the vehicle.
In accordance with additional embodiments of the present invention, methods for pre-programming a vehicle navigation system are disclosed. Location information is received for a limited number of desired destinations as specified by a user. The desired destinations are mapped to a user input interface prior to the user's entering the vehicle.
In accordance with further embodiments of the present invention, methods for providing limited-destination navigational guidance to a user when driving a vehicle are provided. In one embodiment, location information for a limited number of desired destinations is received. The desired destinations are mapped to a user input interface prior to the user's entering the vehicle. GPS data relating to a present position of the vehicle is received. Navigational guidance is provided to the user upon selection of the user input interface. Hence, in lieu of manually entering a destination address, a user may press one button and automatically receive navigational instructions for driving to the user's pre-designated destination.
Reference is now made to
The navigation system 100 includes a processor 120 coupled to a memory 130. The memory 130 may be used to store location information corresponding to one or more pre-programmed destinations specified by the user. The memory 130 may also be used to store location information corresponding to a point of origination, such as, for example, a rental car agency location. Such location information may comprise one or more addresses. Such addresses can include information such as a street address (e.g., 123 Main Street, Schaumburg, Ill. 60196). Such location information may also include positional information, such as GPS coordinates, longitude and latitude coordinates, etc. Such location information may also include a name or label for each destination (e.g., “Hotel,” “Rental Car,” “Airport,” “Hilton®,” “Hertz®,” or “O'Hare,” etc.). Such location information may also include an image or icon representative of each destination.
The navigation system 100 may optionally include a GPS receiver for receiving present location data and map data. In other embodiments, the GPS receiver may be external to the navigation system 100. For example, an external GPS receiver may be located in or coupled to the vehicle 110 and may provide GPS data to the navigation system 100 via a vehicle network interface 140 to a vehicle data bus. Examples of a suitable data bus include without limitation a Controller Area Network (CAN) bus and a Media Oriented Systems Transport (MOST) bus. In some embodiments, GPS data may be provided to the navigation system 100 via wireless transmission. For example, GPS data may be received by a GPS receiver and wirelessly transmitted to the vehicle network interface 140 according to the Bluetooth specification, Wi-Fi, or other wireless communication protocol. GPS data may also be provided to the navigation system 100 via an on-board diagnostic (OBD) connector or other suitable vehicle network interface 140. An embodiment of the navigation system 100 without an internal GPS receiver takes advantage of the fact that many vehicles are already equipped with a GPS receiver, and therefore provides a lower-cost solution.
In some embodiments, the navigation system 100 may receive location information via the vehicle network interface 140. For example, location information may be received by a vehicle transceiver and transmitted to the vehicle network interface 140 via a vehicle data bus. Alternatively, location information may be received by a vehicle transceiver and wirelessly transmitted to the vehicle network interface 140 according to the Bluetooth specification, Wi-Fi, or other wireless communication protocol.
In other embodiments, the location information may be received by a separate interface 150 to an external network. The interface 150 may comprise a communications interface for receiving location information from, for example, a computer or server remote from the vehicle 110. In some embodiments, the interface 150 may comprise a wireless receiver including an antenna and software module for wirelessly receiving location information from a wireless transmitter. For example, the location information may be received by the interface 150 via a Wi-Fi, Bluetooth, cellular, satellite, or other wireless communication channel.
The navigation system 100 further comprises a user interface, which may comprise an input interface 150 and an output interface 160. In some embodiments, the input interface 150 may comprise one or more actuators such as button interfaces. In some embodiments, the input interface 150 may comprise a microphone for receiving audio input from the user. In some embodiments, the output interface 160 may comprise one or more speakers for providing audible navigational information; alternatively, the navigation system 100 may send audio to external speakers in the vehicle 110. In some embodiments, the output interface 160 may comprise a display screen for providing visual navigational information. In some embodiments, certain aspects of the input interface 150 and the output interface 160 may be combined, such as, for example in a touch-screen display.
Reference is now made to
The navigation system 200A may include an output interface comprising a display 210 for displaying graphics and/or text. For example, a graphical user interface may be used to show a map depicting present position 212, present destination 214, and/or route data. In other embodiments, the navigation system 200A may lack a display 210, and may instead provide only audible navigational information (e.g., “Turn right onto Main Street in half a mile,” or beeps or other sounds when a turn should be made, etc.) as a lower-cost solution. The navigation system 200A may comprise one or more speakers 220; alternatively, the navigation system 200A may send audio to external speakers such as speakers of a stereo system in the vehicle. The user interface may also include interactive voice response technologies. In such embodiments, a microphone 230 may be included for receiving voice commands from a user (e.g., “Go to airport” or “Return to car rental agency,” etc.).
In accordance with the present embodiment, the navigation system 200A may provide route instructions for a limited number of pre-programmed destinations. A user input interface 240 is provided which may comprise one or more actuators, such as buttons, for example. The buttons may be implemented as tactile buttons in some embodiments. In some embodiments, the buttons may be implemented in a touch-screen interface. Other suitable input means may be used.
When a particular button is selected, the navigation system 200A provides route instructions to a pre-programmed destination associated with the button. For example, when one of the buttons is selected, the navigation system 200A may provide route instructions to an airport previously designated by the user. In other embodiments, wherein the vehicle is rented from a car rental agency, for example, one of the buttons may provide route instructions to the car rental agency, which may be located at the airport. When another of the buttons is selected, the navigation system 200A may provide route instructions to a hotel previously designated by the user. When another of the buttons is selected, the navigation system 200A may provide route instructions to another destination previously designated by the user. For example, the navigation system 200A may be pre-programmed to provide route instructions to a residence or place of business that the user wishes to visit. The buttons may be labeled with an appropriate icon or text to provide a more user-friendly interface.
The one or more buttons provide a simple, user-friendly interface for the most important destinations to the user. The present embodiment may be particularly useful to a person who is using a rental car on a business trip. For example, the rental car agency (which is typically at the airport), hotel, and office are often the destinations of paramount interest to business travelers.
Reference is now made to
The destinations may be designated by the user when making a reservation for a rental car. As an example, a user may plan a trip to visit Motorola in Schaumburg, Ill. including a stop to visit the home of the user's friend, Terri. The user may make travel arrangements for the trip via a travel web site, and select a flight, a reservation at the Westin hotel, and a rental vehicle from Avis, via the travel web site. The travel web site may provide the user an option to input one or more destinations of interest, and in response, the user may provide the street addresses for Motorola and Terri's house. The travel web site may provide the user an option to select text or graphics or both to be displayed on each of the limited destination navigation system actuators, corresponding to the various destinations of interest. For example, the user may, via the travel web site, configure the navigation system to display the following text on each actuator: “AVIS” (for the actuator that will provide driving directions to the rental car agency selected for the trip); “WESTIN” (for the actuator that will provide the driving directions to the hotel reserved for the trip); “MOTOROLA” (for the actuator that will provide the driving directions to the office to be visited on this trip); and “TERRI” (for the actuator representing the directions to Terri's house which will be visited during this trip). As a result, the user input interface 250 may comprise LCD displays that display the text “AVIS,” “WESTIN,” “MOTOROLA,” and “TERRI.” Images may also be displayed, as shown in
Three actuators are depicted in the embodiment of
Reference is now made to
In some embodiments, the user is prompted to provide the address of a desired destination, such as a city, airport, hotel, or other destination, via the web site or other communication channel. In other embodiments, the user may provide the address of a desired destination (e.g., the street address of a place of business desired to be visited), and the web site or telephone operator may suggest one or more hotels, car rental agencies, and/or airports, etc. proximate to the desired destination. The user may select a specific hotel, car rental agency, and/or airport from the suggested offerings.
If the user indicates that a rental car is desired, the user may be prompted to indicate whether the user desires to have a navigation system in the rental car. If the user indicates that a navigation system is desired, the user may be prompted to indicate whether the user desires a limited-destination navigation system. Such a limited-destination navigation system may be offered at a lower fee than a full-featured navigation system. In some embodiments, a limited-destination navigation system featuring one destination, such as the rental car agency location, may be offered for an even more reduced fee, or no fee at all.
Once the destination information is specified by the user, and the user has been assigned a vehicle, the destination information can be downloaded to the navigation system 100 via the external network interface 170. In some embodiments, the destination information may be transmitted wirelessly via a wireless base station 340 to a wireless receiver located in the rental car 300, and transmitted to the navigation system 100 via a data bus, such as a CAN or MOST bus. In other embodiments, the destination information may be wirelessly transmitted to a wireless receiver included in the navigation system 100 itself. In other embodiments, the destination information may be transmitted to the navigation system 100 from a communications device at the rental car agency that is communicably coupled to the navigation system 100. For example, the navigation system 100 may be communicably coupled to a rental car agency computer or server 350, by way of, for example, a docking station.
Once the location information is downloaded to the navigation system 100, it is ready for use with the rental car 300. The location information may be downloaded to the navigation system 100 at a later point, such as when the user arrives at the car rental agency to pick up the car 300. In some embodiments, the location information may be initially received when the user arrives at the car rental agency to pick up the car 300. In some embodiments, the location information may have already been received by the time that the user arrives at the car rental agency, but the location information can be modified before the user takes possession of the car 300.
The location information is stored in the memory 130 of the navigation system and is mapped to the interface 160. For example, the car rental agency location may correspond to one of the buttons of the interface 240 depicted in
In another embodiment, the input user interface actuators may include simple LCD displays that will allow a user to pre-program text and/or graphics to be displayed on each of the actuators at the time of reservation. If a person is planning a trip on a travel web site, and has selected a hotel, flight information and a vehicle, the travel web site may provide the user the option to select text to be displayed on each of the limited destination navigation system actuators. For example, a user may select the following text to be displayed on each actuator: “O'Hare” (for the actuator that will provide driving directions to O'Hare international airport); “Grand Resort” (for the actuator that will provide the driving directions to the hotel reserved for this trip); and “Uncle Joe's” (for the actuator that will provide the driving directions to visit the user's Uncle Joe's house).
Advantageously, the user is able to pick up the vehicle 300, press a button corresponding to a desired destination, and automatically receive route instructions for that destination, without having to manually program the navigation system 100 or manually enter any address information into the navigation system 100, or fumble with a complicated user interface. When the user is ready to travel to the designated hotel, the user can press another button and receive route instructions for driving to the hotel. When the user is ready to travel to another desired destination, such as an office, the user can press another button and receive route instructions for driving to that destination. When the user is ready to return the vehicle, the user can press another button and receive route instructions for driving to the car rental agency.
Accordingly, embodiments of the present invention advantageously save time by providing the user with a simple, quick, and user-friendly interface for receiving route guidance for a destination. By pre-programming destinations selected by the user, the navigation systems of the present embodiments allow the user to avoid wasting time and effort which would otherwise be spent in manually programming a more complex navigation system and fumbling with a more complex user interface. The time-saving features of the present invention may be particularly beneficial when time is of the essence, for example, when business travelers and other users are running late to a meeting or are running late to the airport, and need quick, user-friendly navigational guidance.
It should be understood that the inventive concepts disclosed herein are capable of many modifications. To the extent such modifications fall within the scope of the appended claims and their equivalents, they are intended to be covered by this patent.
