After processing, same will process after data carry out synchronization and compare, if comparison result is consistent, then assert system work
Normally.
(4) under normal condition, after last step, graphic display processor A its image processing module is controlled
Realize the control function of display module A；Meanwhile, graphic display processor B its image processing module realization display mould is controlled
The control function of block B.All information that i.e. automobile instrument shows are provided with control system B jointly by controlling system A.
(5) in particular cases, if system master MCU A fault, MCU A receives not processing from CAN
Information, is compared by synchronizing information, and system judges MCU A fault, will isolate this faulty component rapidly and (i.e. control system A
Do not export control signal), and report to the police.Meanwhile, system master MCU B works on, logical after the velocity information received being processed
Cross graphic display processor B and be uploaded to display module A and display module B, it is ensured that the basic display function of automobile instrument equipment.
(6) system B is controlled this fault alarm information (MCU A fault) is straight by display screen and speaker (sound and light alarm)
That sees shows, the information reminding driver's automobile instrument to show there may be bigger error, only for reference, need to carefully drive
Sail, keep in repair as early as possible.
(7) fault mode of automobile instrument control system has a variety of, its processing procedure implemented and system handover mechanism
Similar with said method.
The system of the present embodiment will be supplied to the more accurately more detailed vehicle operating parameter of driver and internal car systems
Work state information, ensures the safety traffic of automobile and safeguards traffic safety；Fast and accurately oneself state can be examined
Survey, can effectively reduce the fault rate of system, and it can be avoided that factors such as the deviations that caused due to external disturbance of system, from
And safety and the accuracy of system can be promoted, meet the demand for security of user.The present invention is reasonable in design, easy for installation, intelligence
Change degree is high, and reliability and safety are high, and versatility is good, and using effect is good, it is simple to promote the use of.
