The invention provides an automobile combined instrument. The automobile combined instrument comprises a combined instrument module and a combined instrument LCD screen. The combined instrument module transmits display information to a loudspeaker main chip through a communication bus. The loudspeaker main chip drives display of the combined instrument LCD screen through a communication bus. The combined instrument LCD screen is completely driven by existing functions of the loudspeaker main chip to conduct display, and therefore display drive circuit modules are reduced for the combined instrument module on the aspect of hardware while the cost of the main chip of a loudspeaker system is not increased, a hardware circuit of the combined instrument module can be greatly simplified, and meanwhile cost of a combined instrument system can be greatly reduced.
