A, automobile sensor send fault-signal and be transported to handle in the automobile central microprocessor after, but send on the CAN bus interface of continuous monitoring vehicle failure device by the CAN bus transmitter on the automobile, after the input end of CAN bus intelligence receiver module receives signal, be processed into the signal of the microprocessor input request signal that meets band A/D conversion and be delivered to the I/O mouth of the microprocessor of band A/D conversion, after the microprocessor of band A/D conversion receives this signal, through exporting control signal corresponding after computing and the logical process, show corresponding fault additional character by the liquid crystal drive display module, show that supporting Chinese or English words carry out the fault prompting and make loudspeaker send corresponding supporting Chinese or English Phonetics by voice cue module;
The microprocessor of B, band A/D conversion with a large amount of automobile fault information deposit data in the failure message storer;
The microprocessor of C, band A/D conversion switches according to function and the state that is provided with that circuit is set is made different disposal, corresponding each parts operation of indication.
D, when exceeding the scope of setting and the stuffy degree of Che Nei and exceed standard as vehicle interior temperature, the microprocessor of band A/D conversion can be regulated vehicle interior temperature automatically to being provided with in the scope, regulates with fresh air spending to normal range in the car automatically.
9, Vehicular real time intelligent failure monitoring method according to claim 8, when it is characterized in that needs take out the vehicle failure data, the microprocessor of band A/D conversion is accepted the instruction that the UBS manager is sent, and by the UBS manager fault information data in the storer is read at the UBS interface.
