Abstract

The invention relates to the technical field of USB-HUB systems, in particular to a Carplay and Device port compatible USB-HUB system. The Carplay and Device port compatible USB-HUB system comprises a USB port extension chip, wherein a data uploading / downloading interface end which is connected with vehicle-mounted multimedia equipment and a physical layer interface end which is connected with mobile equipment are arranged on the USB port extension chip; a USB switching chip is connected with the physical layer interface end; an input interface structure is arranged at an output end of the USB switching chip; and a switching switch is arranged on the USB switching chip. The invention aims at providing the Carplay and Device port compatible USB-HUB system; and by adopting the technical scheme provided by the invention, the technical problem that the conventional Microchip USB84604 technology needs to carry out port appointment during the use is solved, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of USB-HUB systems, in particular to a USB-HUB system compatible with Carplay and Device ports. Background technique [0002] In the existing vehicle multimedia system, the data connection adopts USB-HUB, that is, the USB port expander system for data transmission. [0003] CarPlay is an in-vehicle system released by Apple Inc., which seamlessly integrates the user's iOS device, iOS experience and dashboard system. CarPlay only supports iPhones with a Lightning interface, and although the iPad already supports this interface, Apple does not list the iPad as a hardware device supported by CarPlay. With the popularity of Apple devices and the development and maturity of in-vehicle interconnection technology, the Carplay function has increasingly become one of the main functions of in-vehicle entertainment systems. Carplay communication requires USB role exchange between the Host and Carplay devices. In addit...
