Similarly, a second set of vehicle devices may operate on a second vehicle network, a third set of vehicle devices may operate on a third vehicle network, etc. Gateway module 10 and the second and third sets of vehicle devices are connected to one another through the second and third vehicle networks, respectively. In each case, vehicle devices operating on a vehicle network use that network to exchange information with one another and/or gateway module 10.
Gateway module 10 enables communication between vehicle devices operating on different vehicle networks. Gateway module 10 enables such communication in either case of the vehicle networks being of the same type or of different types. Vehicle networks of the same type use the same communication protocol whereas vehicle networks of different types use different communication protocols from one another.
For example, as shown in
Each vehicle network may connect with none or one or more vehicle devices operating on the network. For instance, first CAN 12 may be a vehicle powertrain CAN bus including engine, transmission, and brake controllers as well as other directly related sensors and actuators. Second CAN 14 may be a comfort or body CAN bus used to run comfort systems such as power windows, seat memory, tire pressure, etc. First LIN 18 may be an application LIN bus for applications such as an air conditioner or wiper control. MOST network 24 may be an infotainment MOST bus.
Vehicle networks 12, 14, 16, 18, 20, 22, 24, and 26 are either of the same type and use the same communication protocol or of different types and use different communication protocols. For instance, CANs 12, 14, and 16 are of the same type and use the same communication protocol. Likewise, LINs 18 and 26 are of the same type and use the same communication protocol. However, the communication protocol used by CANs 12, 14, and 16 is different than the communication protocol used by LINSs 18 and 26. Each of the other networks 20, 22, and 24 use their own communication protocol different than the communication protocols of any of the other networks. As such, gateway module 10 is configured to function as a translator in enabling communication between vehicle devices operating on vehicle networks employing different communication protocols. In general, gateway module 10 manages network traffic on vehicle networks connected to the gateway module.
Gateway module 10 further includes an embedded cellular data link 28. Cellular data link 28 provides gateway module 10 with cellular data network connectivity. Cellular data link 28 such as a 3G or 4G data link is a direct connection between gateway module 10 and an external Internet access node of an Internet access provider. The Internet access node is in communication with the Internet. As such, gateway module 10 is configured to use a cellular data network for Internet connectivity and such connectivity is “always on.”
Gateway module 10 further includes at least one embedded wireless link 30 and 32. In this embodiment, gateway module 10 includes first and second wireless links 30 and 32. Each wireless link 30, 32 provides gateway module 10 with short range wireless connectivity. For example, first wireless link 30 is a WiFi™ link and second wireless link 32 is a Bluetooth™ wireless link.

In particular, cellular data link 28 provides a direct cellular connection between gateway module 10 and an Internet access node 50 in communication with the Internet. Wireless links 30 and/or 32 provide a direct wireless connection between gateway module 10 and mobile devices 64. As a result, communication between mobile devices 64 and the Internet can take place via cellular data link 28 and wireless links 30 and/or 32. In this regard, cellular data link 28 and wireless links 30 and/or 32 provide cellular data network connectivity in conjunction with wireless connectivity, respectively, for establishing hotspot 62 within vehicle 60.
Additionally, other communication paths can be established from the hotspot functionality: gateway module to cellular internet; gateway module to vehicle; gateway module to mobile devices; and gateway module hotspot.

As shown in
In environment 40, gateway module 10 is in communication with vehicle devices 44, 46, and 48 connected to vehicle networks 12 and 20 connected to the gateway module. Gateway module 10 is also in communication with a remote entity 53 via cellular data link 28 and with a mobile device 64 within vehicle 60 via wireless data link 30 and/or 32. As used herein, a remote entity is an entity (i.e., provider, connection) remotely located far enough away from gateway module 10 that communication with gateway module 10 can only take place via cellular data link 28 and not via wireless links 30 or 32.
In particular, cellular data link 28 provides a direct connection between gateway module 10 and an Internet access node 50 in communication with the Internet 52. Remote entity 53 is independently connected to the Internet 52. As such, gateway module 10 is in communication with remote entity 53 via cellular data link 28. Wireless data link 30 and/or 32 provides a direct connection between gateway module 10 and mobile devices 64. As such, gateway module 10 is in communication with mobile devices 64 via wireless data link 30 and/or 32. As gateway module 10 is in communication with remote entity 53 via cellular data link 28 and with mobile device 64 via wireless data link 30 and/or 32, mobile device 64 and remote entity 53 are in communication with one another via cellular data link 28, wireless data link 30 and/or 32, and gateway module 10. Accordingly, communication between mobile device 64 and remote entity 53 can take place via cellular data link 28, wireless data link 30 and/or 32, and gateway module 10.
As described, gateway module 10 is also in communication with devices 44 and 46 on CAN 12 and device 48 on Ethernet network 20. Accordingly, communication between any of devices 44, 46, and 48 and mobile device 64 and remote entity 53 can take place via cellular data link 28, wireless data link 30 and/or 32, and gateway module 10.
In an embodiment, remote entity 53 communicates with a vehicle device, such as vehicle device 48, via cellular data link 28 and gateway module 10 in conjunction with communicating with mobile device 64 via cellular data link 28 and wireless data link 30 and/or 32. For instance, remote entity 53 communicates with vehicle device 48 to remotely control the vehicle device in response to a command regarding same communicated from mobile device 64 to remote entity 53. Such remote control functions include remote start, vehicle unlock, setting temperature, etc. As another example, remote entity 53 communicates with vehicle device 48 to obtain diagnostic information from the vehicle device in response to a request or an authorization regarding same communicated from mobile device 64 to remote entity 53. Such diagnostic information includes traction battery conditions, tire pressure, fault conditions, etc. As another example, remote entity 53 communicates with vehicle device 48 for some purpose and communicates some sort of notification regarding same to mobile device 64.
In an embodiment, remote entity 53 communicates re-flash software to gateway module 10 via cellular data link 28 in response to receiving a request regarding same communicated from mobile device 64 via cellular data link 28 and wireless data link 30 and/or 32. The re-flash software is for receipt by one or more of vehicle devices 44, 46, and 48 such as device 44. The re-flash software is communicated from remote entity 53 to recipient device 44 over vehicle network 12 via gateway module 10 and cellular data link 28. In this manner, the re-flash software is directly downloaded “over the air” to the recipient device 44 in response to a request from mobile device 64.
In an embodiment, a fourth vehicle device 49 of vehicle 42 is connected to gateway module 10 by only a wireless link 30 and/or 32. Vehicle device 49 is a controller of any number of body, chassis, and/or engine functions that is permanently mounted in vehicle 42, but which communicates with other vehicle devices 44, 46, and/or 48 wirelessly (via gateway module 10).
As described, cellular data link 28 of gateway module 10 is an “always on” external data connection and wireless link 30 and/or 32 is an always on internal data connection. As a result, gateway module 10 provides an always on Internet or wireless hotspot accessible to vehicle occupant mobile devices 64.
As gateway module 10 is a central vehicle hub the gateway module 10 has access to the vehicle networks connected to the gateway module and can thereby manage cyber security, diagnostics, over-the-air re-flashing, and the like. Therefore, in addition to the benefits provided by an in-vehicle Internet or wireless hotspot, it is advantageous that gateway module 10 provides the Internet or wireless hotspot.
