Abstract:
Systems and methods are provided for enabling an over-the-air update to a plurality of vehicles. A system and method include transmitting a wakeup signal over a communication network to the vehicles that are in a listen state. The update is transmitted over the Wi-Fi network to the vehicles. The transmitting of the update over the Wi-Fi network includes using a transmission scheme to overcome asynchronous communication wakeup of the vehicles.
Abstract:
A wireless vehicle-trailer interface system for communication between a vehicle and a trailer is provided. The vehicle may include a vehicle hitch, a vehicle control system, a vehicle radio frequency system, and a processor, the processor configured to generate a unique data packet for each vehicle radio frequency system, determine, for each received response packet, a distance between a corresponding receiving vehicle radio frequency system and a corresponding transmitting trailer radio frequency systems, determine a relative physical position of each vehicle radio frequency system and trailer radio frequency system, determine dimensions of the trailer, determine a physical position of a vehicle hitch and a trailer coupled, and generate instructions for the vehicle control system to cause the vehicle to move to align the vehicle hitch with a trailer coupler.
Abstract:
A system and method that enables large content data transfers to mobile platforms is provided. The mobile platform cache system and method provided build a cache suitable for large content data transfers using the available storage capacity of one or more frequently used, existing mobile devices. The provided mobile cache system and method prioritize available free or low cost communication protocols for data transfer to one or more mobile devices, enabling the use of free Wi-Fi communications or low cost communications, and minimizing the use of cellular data transmissions for large content data transfers.
Abstract:
A social media system for a vehicle and a method of operating the social media system are provided. The social media system, for example, may include, but is not limited to a camera, an interface, a memory configured to store one or more safety settings, and a processor communicatively coupled to the camera, the interface and the memory, the processor being configured to receive, via the interface, a command request to utilize the social media system, determine, based upon the safety settings stored in the memory, when the command request may be completed, and executing the command request when the processor determines that command request may be completed.
Abstract:
Systems and methods are provided for securing and authenticating a network of a vehicle. At least one network key is generated by an electronic control module and distributed to at least one remote device over a wired power line. At least one signed transmission having a signature based on the at least one network key is transmitted from the at least one remote device to the electronic control module over a communication channel on the network separate from the wired power line. The electronic control module authenticates and encrypts the at least one signed transmission and receives a data stream from the at least one remote device over the communication channel.
Abstract:
Methods and systems are provided for facilitating communication with a base station. The system includes a plurality of relay nodes configured to communicate wirelessly via primary communications links with the base station and transmit operational data to the base station and/or at least another of the relay nodes. At least one controller is configured to determine which of the plurality of relay nodes to place in an active state based at least partially on the operational data.
Abstract:
A passive entry-passive start portable device detection system. A portable device includes a transceiver. At least one vehicle-based transceiver broadcasts an interrogation signal. The transceiver of the portable device transmits a response signal in response to the interrogation signal. A controller determining at least a range of the portable device as a function of the time-of-flight of the interrogation and response signals. The controller controls a measurement duty cycle of the interrogation signal as a function of the determined range
Abstract:
A method of planning communication network infrastructure includes calculating a potential capacity of a plurality of vehicular relay nodes in an area, wherein the plurality of vehicular relay nodes relay data between a plurality of portable devices and at least one base station. The method also includes calculating a potential data demand in the area for transferring data between the plurality of portable devices and the at least one base station. The method further includes determining whether the number of base stations serving the area is sufficient by utilizing the potential capacity of the plurality of vehicular relay nodes in the area and the potential data demand in the area.

Abstract:
Methods and systems are provided for facilitating communication. The system includes a portable device and a base station. The system also includes a vehicle-based device configured to communicate wirelessly via a first communications link with the portable device, communicate via a second communications link with the base station, and relay data between the first communications link and the second communications link. The portable device is configured to determine a quality of the first communications link and reduce an emitted power in response to the quality of the first communications link being higher than a predetermined threshold.
