If butterfly valve can reach lower dead center, it is determined that carbon cleaning is finished, and control to exit automatically cleaning pattern, extinguish simultaneously
Automatically cleaning trouble light；
In the embodiment, if butterfly valve can move to lower dead center, illustrate that the carbon distribution on butterfly valve is removed substantially and finish,
Automatically cleaning pattern can be exited with control system.
If butterfly valve can not move to lower dead center, continue to repeat in target location step motion, until reaching air throttle certainly
The time limit is cleaned, and detects determination automatically cleaning procedure failure, the normal bright and Write fault internal memory of triggering automatically cleaning trouble light.
In the embodiment, if butterfly valve can not move to lower dead center within the automatically cleaning time limit, it was demonstrated that the carbon distribution on butterfly valve does not have
Cleaning is completed, system detectio automatically cleaning failure, and fault data is stored.Wherein, during automatically cleaning, it is if reaching
Unite the default automatically cleaning time limit, no matter whether carbon distribution is removed and finished, directly exit automatically cleaning pattern.
As shown in figure 4, the process that implements of the above method includes：
Step 41, after electricity under engine, ECU judges whether Vehicular system meets automatically cleaning condition, if it is not satisfied, then straight
Connect and exit automatically cleaning pattern；
If step 42, meeting automatically cleaning condition, the initial value of the system variable during automatically cleaning is preset, assigned
The desired value for giving butterfly valve to control；
Step 43, by controlling butterfly valve to be moved to target location, judge the order of severity of carbon distribution；
If step 44, butterfly valve do not have obvious carbon distribution, heating wire is controlled with Partial Power heated mould by power governor
Formula is heated, and exits automatically cleaning pattern in the completed；
If step 45, carbon distribution are serious, heating wire is controlled to be heated with heating with full power pattern by power governor, and control
Automatically cleaning trouble light high frequency flicker；
After step 46, heating wire are with heating with full power pattern heating preset time, by controlling butterfly valve to be moved to lower dead center,
Check whether carbon distribution is removed；If removing is finished, automatically cleaning pattern is exited in control；
If step 47, removing and not completing, automatically cleaning trouble light is lighted in control, and control is exited from clear after storage fault data
Clean pattern.
It should be noted that the air throttle carbon distribution self cleaning method is method corresponding with above-mentioned throttle valve structure, it is above-mentioned
All implementations can also reach identical technique effect suitable for the embodiment of this method in constructive embodiment.
The present invention the embodiment, when engine is shut down, system initiative recognition carbon distribution situation, and select be adapted to from clearly
Clean pattern, the working method heated using throttle body butterfly valve is carried out two-step evolution to the power of heating, passes through heating evaporation butterfly
Carbon distribution on valve, realizes throttle body automatically cleaning, the problem of can efficiently solving air throttle carbon distribution, while being engine control
Unit ECU control strategies and throttle body design and develop offer reference.
Above-described is the preferred embodiment of the present invention, it should be pointed out that come for the ordinary person of the art
