Description
Technical field
The present invention relates to USB-HUB systems technology field, particularly relate to a kind of compatible Carplay and Device port
USB-HUB system.
Background technology
In existing in-vehicle multi-media system, data cube computation all uses USB-HUB, i.e. USB port expander system is carried out
Data are transmitted.
CarPlay is the onboard system that American apple company issues, and it is by the iOS device of user, iOS experience and instrument
Dial plate system seamless combination.CarPlay only supports to have the iPhone mobile phone of Lightning interface, additionally while iPad is
Through supporting this interface, but iPad is not classified as the hardware device that CarPlay supports by apple.General with apple equipment
And, the development of vehicle-mounted interconnection technique and maturation, Carplay function is increasingly becoming one of vehicle entertainment system major function.
Needing to carry out between Host and Carplay equipment USB role exchange during Carplay communication, additionally Carplay function needs great Rong
The data transmission of amount, it is very high to usb signal quality requirement, therefore on the premise of realizing USB role exchange, can promote again
The USB-HUB scheme Microchip USB84604 of usb signal quality arises at the historic moment.
As it is shown in figure 1, brand-new USB84604UCH2 uses FlexConnect technology, and a uplink port is had to support
Connect between USB2.0 and USB high-speed chip, therefore for the automotive infotainment design needing a large amount of USB port and connection
For be the choosing of ideal.The FlexConnect technology of Microchip can easily realize Port inversion or " role exchange " simultaneously,
Cater to the demand to " networking automobile " for the consumer.The downlink port of USB84604 can exchange with up host port, will be main
Machine function forwards to be connected on the product of UCH2, such as smart mobile phone and panel computer.The characteristic of this uniqueness makes by software
The smart mobile phone ecosystem constituting with application program can access in automotive infotainment.
Under the carefully studying and verify of inventor, find that existing Microchip USB84604 technology has following lacking
Fall into:
USB84604 only one of which switching layer swap PHY, as in figure 2 it is shown, therefore product use CARPLAY when need right
CARPLAY and DEVICE port is specified, and affects Consumer's Experience.
Content of the invention
The goal of the invention of the present invention is to provide the USB-HUB system of a kind of compatible Carplay and Device port, uses
The technical scheme that the present invention provides solves existing Microchip USB84604 technology to be needed to carry out port appointment in use,
Affect the technical problem of Consumer's Experience.
In order to solve above-mentioned technical problem, the present invention provides the USB-HUB system of a kind of compatible Carplay and Device port
System, including USB port extended chip, is provided with for being connected with vehicle-mounted multimedia equipment on described USB port extended chip
Upload and download data-interface end, and the physical layer interface port being connected with mobile device, company at described physical layer interface port
Connect and be provided with USB switching chip；Output at described USB switching chip is provided with input interface structure；In described USB switching
It is provided with switching switch on chip.
Preferably, described input interface structure is USB port and Lightning interface.
Therefore, the technical scheme of the application embodiment of the present invention, have the advantages that:
The present invention is provided with USB switching chip between physical layer interface port and mobile device, by USB switching chip
Switching switch USB port is switched over, two USB ports can be carried out port selection, USB-HUB by USB Switch
Chip carries out the role transforming between Host and Device thus realizes Carplay function and USB Device function, it is not necessary to
The port of Carplay is specified, improves Consumer's Experience.
