The processor 16 is electrically connected to the memory 13 and the receiver 14. The downlink processor 17 is connected to the radio system 18 via a network link, such as car area network (CAN), and audio circuitry. The audio circuitry provides audio capability in an analog format.
The receiver 14 is configured to receive a broadcast signal containing information about a user-defined geographic region. The information includes a broadcast identification number.
The broadcast signal is a satellite signal. The broadcast signal, however, may be of other types.
The information about a user-defined geographic region includes a zip code and radius defining the geographic area for which a user is interested in hearing information. Other criteria, such as an area defined by a set of latitude and longitude coordinates, may also be used.
The broadcast identification number is a number unique to the user's particular vehicle 12 and matches the vehicle's identification or electronic serial number. The broadcast identification number is used by the processor 16 to determine whether certain broadcast information pertains to the vehicle 12 as will be explained below in detail.
The user can update the information about their user-defined geographic region via a website or other data channel that is in communication with a central data hub. For example, a user may wish to change the zip code from a default zip code set by the vehicle dealer or manufacturing facility. The user includes their broadcast identification number along with their updated information. Before broadcasting the information, the central data hub packages the broadcast identification number with the updated information. A vehicle receiving the broadcast information can use the broadcast identification number to determine whether to download and store the updated information as will be explained below in detail.
The receiver 14 is also configured to receive a broadcast signal containing information. The information includes a geographic location associated with an event.
The broadcast signal is a satellite signal. The broadcast signal, however, may be of other types.
The information, for example, includes information about one or more incidents, e.g., traffic events, in different locations. The location of particular incidents is indicated by a zip code or a latitude and longitude. Other geographic indicators, however, may be used.
A set of incident data for a particular location is packaged and broadcast by location sequentially. For example, traffic event information associated with a particular zip code may be packaged and broadcast followed by traffic event information for a different zip code.
The processor 16 is configured to store an identification number unique to the vehicle, e.g., an electronic serial number. This identification number may be input during manufacturing via a physical data link or wireless transmission. The electronic serial number is stored in memory 13.
The processor 16 is also configured to store information about a user-defined geographic region. This information may come from a dealer, manufacturer, or vehicle user. For example, after the vehicle 12 is manufactured, a dealer may input a default geographic region to the DLP 17 via a physical data link or a wireless transmission. The default geographic region may be the zip code in which the dealer is located. As explained above, a user may also update the geographic region information. The information about a user-defined geographic region is stored in memory 13.
The processor 16 is also configured to process the signal containing the information to determine whether at least a portion of the information pertains to the user-defined geographic region.
The processor 16 determines, for example, whether the zip code associated with a set of traffic event information falls within the specified radius of the user-defined zip code. If it does, the traffic event information pertains to the user-defined geographic region. If it does not, the traffic event information does not pertain to the user-defined geographic region.
The processor 16 is also configured to store at least a portion of the event information pertaining to the user-defined desired geographic region. As the processor 16 parses through the event information and determines whether a given event pertains to the user-defined geographic region, the processor 16 is configured to store one or more events pertaining to the user-defined geographic region. The event information is stored in memory 13.
The processor 16 is also configured to automatically generate a signal capable of being made audible when at least a portion of the information pertains to the user. The signal is forwarded from the DLP 17 via the audio circuitry to the radio system 18. The signal is then played by the speaker 19. The signal may also include a non-audio component, such as information for text or an icon, to be displayed on a display screen. The non-audio component of the signal may be sent over the network link or through a wireless transmission.
The processor 16 is further configured to process the signal containing the information about the user-defined geographic region, or other criteria, to determine whether the identification number unique to the vehicle matches the broadcast identification number. The processor 16 thus determines whether the information about the user-defined geographic region pertains to the vehicle 12. If the broadcast identification number matches the identification number unique to the vehicle the information about the user-defined geographic region pertains to the vehicle 12. If the broadcast identification number does not match the identification number unique to the vehicle, the information about the user-defined geographic region does not pertain to the vehicle 12.
The processor 16 is still further configured to store the information about the user-defined geographic region when the identification number unique to the vehicle matches the broadcast identification number. The information is stored in memory 13.
The processor 16 is further configured to automatically generate an information signal capable of being made audible by, for example, the speaker 19, containing the stored information. The signal is forwarded from the DLP 17 via the audio circuitry to the radio system 18. The signal is then played by the speaker 19. The signal may also include a non-audio component, such as information for text or an icon, to be displayed on a display screen. The non-audio component of the signal may be sent over the network link or through a wireless transmission.
