In order to solve the problems that a vehicle-mounted terminal Android system software decoding process is overloaded and a vehicle-mounted terminal cannot expand the visual field of a driver, the invention provides a vehicle-mounted interconnected video display acceleration device. The vehicle-mounted interconnected video display acceleration device comprises a video hardware decoding unit, an instruction processing unit, a display processing unit and a touch display, wherein the video hardware decoding unit is connected with a mobile terminal through a USB interface, receives a video code stream from the mobile terminal, decodes the video code stream and sends the decoded video code stream to the display processing unit; the display processing unit is electrically connected with the touch display and controls the touch display to display content; the touch display acquires a user operation instruction and sends the user operation instruction to the instruction processing unit; the instruction processing unit is connected with the mobile terminal through a USB interface and sends a user operation instruction to the mobile terminal through the USB interface. According to the invention, the resource consumption of the vehicle-mounted terminal caused by soft decoding in video picture display is avoided, and the problem of video picture delay lag is effectively solved.
