The invention provides a vehicle-mounted terminal screen projection method and system, and the method comprises the steps: building a physical communication connection between an intelligent terminal and a vehicle-mounted terminal, the intelligent terminal is provided with a screen projection sending application and a first virtual machine, and the vehicle-mounted terminal is provided with a screen projection receiving application and a second virtual machine; the intelligent terminal sends an instruction for hanging up a second virtual machine of the vehicle-mounted terminal, and the vehicle-mounted terminal hangs up the second virtual machine according to the instruction and sends related files of the second virtual machine to the intelligent terminal; after the intelligent terminal receives the related file, the intelligent terminal starts the first virtual machine based on the configuration information of the second virtual machine, a running state file of the second virtual machine is recovered on the intelligent terminal, and a picture of the first virtual machine is sent to the vehicle terminal for screen projection display. According to the scheme, the vehicle end application can be operated at the mobile phone end, the problem that the computing power of a vehicle machine is limited is avoided, and smooth operation of the vehicle end application can be guaranteed.
Description
technical field [0001] The invention belongs to the field of computers, and in particular relates to a method and system for car-machine screen projection. Background technique [0002] After the vehicle leaves the factory, the hardware environment of the vehicle terminal has been fixed and cannot be upgraded. With the replacement of in-vehicle software, the computing power requirements are getting higher and higher, which will cause the vehicle to run slower and slower. Therefore, the vehicle terminal will use the mobile phone interconnection technology to screen the applications on the mobile phone. When it is not connected, applications such as navigation, music, and voice can be run on the vehicle terminal. After the mobile phone is connected, these applications will be run on the mobile phone, and the operating interface of these software will be encoded into a video stream and sent to the vehicle terminal for decoding and display. Save computing power. [0003] Howe...
