Abstract

The invention provides an automobile, an automobile instrument and a control method thereof. The automobile instrument comprises a micro control unit MCU, a central processor CPU, a display processor and a display screen; the MCU is respectively connected with the CPU and the display processor; the display processor is also connected with the CPU and the display screen; when the MCU judges that the CPU has no fault, the MCU transmits vehicle information to the CPU, the display processor transmits a decoded backing video signal to the CPU, and the CPU generates main display information according to the vehicle information and the backing video signal and drives the display screen to display the main display information through the display processor; and when the MCU judges that the CPU has a fault, the MCU transmits the vehicle information to the display processor, and the display processor generates backup display information according to the vehicle information and the backing video signal and drives the display screen to display the backup display information. According to the automobile, the automobile instrument and the control method thereof, two display modes are provided so that a problem of blank screen of the display screen of the automobile instrument in the related technologies can be solved and the driving safety can be enhanced.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an automobile, an automobile instrument and a control method thereof.
