Embodiment Construction

[0053]The method described below suppresses undesired termination of a mirroring session between a mobile device and a vehicle display. A mirroring session is a type of data communication session that enables mirrored data displayable on a mobile device to be provided to a vehicle user via a vehicle display. First, a communication link between the mobile device and the display is established using one of several means; for example, using a wired link (eg, USB) or a wireless link (eg, such as Wi-Fi, Wi-Fi Direct Wi-Fi Direct or Bluetooth short-range wireless communication). A mirroring session can then be established and maintained via the communication link. A mirrored session includes any data session that provides mirrored data. And, mirror data may mainly include image data such as digital graphics and / or streaming video data. In some implementations, mirrored data also includes control data or other data types, but this is not required. For example, in Miracast TM In ...

Abstract

A communication system that includes a vehicle and a mobile device, and a method of continuing a mirroring session between the mobile device and a display in the vehicle, which is carried out using the communication system. The method includes the steps of: establishing the mirroring session between the mobile device and the vehicle display; providing mirroring data from the mobile device to the vehicle display via the mirroring session; receiving at the mobile device a keep-alive message from the vehicle display; and in response to receiving the keep-alive message, continuing the mirroring session following an initiation of an inactivity mode of the mobile device.

Description

technical field [0001] The present invention relates to maintaining data communication between a mobile device and a vehicle display, and more particularly to maintaining a data communication session when a portion of the mobile device becomes temporarily inactive. Background technique [0002] MirrorLink by the Car Connectivity Consortium TM Provides connectivity between a smartphone and a vehicle's infotainment system. Utilize USB, Bluetooth or Wi-Fi connection and MirrorLink TM , the application on the smartphone is available and / or accessible through a screen on the vehicle's infotainment system. For example, applications stored and executed on the mobile device can be viewed on the infotainment system display and use the infotainment system controller (e.g., MirrorLink TM Call it Virtual Network Computing or VNC). [0003] Miracast TM (a certification program associated with the Wi-Fi Alliance) defines a peer-to-peer protocol that can be used to connect a user's sm...
