Embodiment Construction

[0055] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0056] refer to figure 1 , the expansion method of the vehicle-mounted system USB of an embodiment of the present invention, comprising:

[0057] S1: Obtain parameter information respectively corresponding to each first node of the first HUB directly connected to the USB of the vehicle system.

[0058] The HUB in this embodiment refers to a device that can expand one USB interface into multiple ones and enable these interfaces to be used at the same time. In this step, by adding the HUB chip of the first HUB directly connected to the vehicle-mounted system USB on the hardware, the information of the HUB chip is specific to the corresponding parameter information of each node of the first HUB, so that the vehicle-mounted system can independently identify the corresponding parameter information, Each first node of the...

Abstract

The invention discloses an expansion method for a USB of a vehicle-mounted system, and the vehicle-mounted system. The expansion method for the USB of the vehicle-mounted system comprises the steps ofobtaining parameter information corresponding to first nodes of a first HUB directly connected with the USB of the vehicle-mounted system; according to the parameter information corresponding to thefirst nodes, matching first channel paths connected with the vehicle-mounted system for the first nodes respectively; and according to the first channel paths, accessing a first external device of thefirst nodes corresponding to the first channel paths. Different parameter information is allocated for the nodes of the first HUB, so that the nodes of the first HUB serve as independent USB OTGs; and the channel paths connected with the vehicle-mounted system are deployed for the independent USB OTGs, so that the original USB of the vehicle-mounted system is expanded into the multiple independent USB OTGs to meet comprehensive development demands of the vehicle-mounted system.

Description

technical field [0001] The invention relates to a vehicle-mounted system, in particular to a method for extending the USB of the vehicle-mounted system and the vehicle-mounted system. Background technique [0002] With the development of modern automobile industry and electronic technology, electronic systems such as vehicle navigation, communication, multimedia audio-visual entertainment, etc. can be networked through network technology to form a powerful comprehensive vehicle system. The future vehicle-mounted system will develop towards an integrated, intelligent, and fully graphical information platform. The vehicle-mounted system can not only provide navigation functions, but also has multimedia audio-visual entertainment functions, which can perform satellite digital broadcast reception, vehicle-mounted digital TV reception, CD / DVD playback, etc., providing users with more abundant application options to meet the needs of users. Requirements for entertainment and comf...
