Embodiment Construction

[0016] The present invention is a system and method for realizing the interconnection between vehicle-mounted computer and smart phone by utilizing MHL, which is to connect the smart phone to the MHL interface of the car host, and the car host performs conversion calculation on the resolution of the car touch screen and the display screen of the smart phone , to keep the coordinates in the touch screen of the car synchronized with the coordinates of the mobile phone. In the process of synchronizing the coordinates of the car touch screen with the coordinates of the mobile phone, the coordinate information is transmitted by means of Bluetooth transmission. By establishing the HID protocol in the Bluetooth module of the mobile phone and the car host, the function mutual control between the car host and the mobile phone is realized. Various functional software displayed on the touch screen of the mobile phone can be operated on the touch screen of the car, and any software on the ...

Abstract

The invention discloses a system and a method for realizing control of a mobile phone by an automobile computer through a MHL (Mobile High-Definition Link). The system and the method are characterized in that a smart phone is connected to a data interface of an automobile host, and the automobile host performs conversion operation for resolution of a touch display screen of the automobile computer and the resolution of the touch display screen of the smart phone, and keeps synchronism between a coordinate touched in the automobile touch screen and a coordinate position of the smart phone. The system and the method can realize functions, such as mutual control, resource sharing and downloading, of the automobile computer and the smart phone. The system and the method are simple to operate, and have good promotional value.

Description

technical field [0001] The invention relates to the technical field of automobile equipment, in particular to a system and a method for realizing the control of a mobile phone by a vehicle-mounted computer using MHL. Background technique [0002] MobileHigh-DefinitionLink (MHL) mobile terminal high-definition audio-visual standard interface is a standard audio-visual interface for connecting portable consumer electronic devices. MHL only uses one signal cable and can be presented on a high-definition TV through a standard HDMI input interface. It uses the existing MicroUSB interface, whether it is a mobile phone, a digital camera, a digital video camera or a portable multimedia player, it can directly transmit the complete media content to the TV without compromising the high-resolution effect of the film. As my country's car sales leap to the world's first market, the ownership of private cars has reached a very high level, using the existing MHL technology can be used to c...
