Description
Technical field
The present invention relates to automobile exhaust gas recirculating system detection technique field, particularly a kind of detection electronic throttle is complete
Closed position maintains the device and method of state.
Background technology
Air throttle is one of controllable valve for controlling air to enter engine, and gas can be with gasoline, bavin after entering air inlet pipe
Oil is mixed into combustion mixture, so as to work by combustion.Air throttle is traditionally divided into mechanical and two kinds of electronic throttle, mechanically
Air throttle passes through drag-line（Stone dead wire）Or pull bar is connected and worked with gas pedal, electronic throttle then mainly passes through solar term
Energy needed for the signal combination engine of door position sensor feedback automatically controls the opening angle of air throttle, so as to adjust
The size of air inflow.So far, because the raising of levels of emissions, mechanical throttle do not adapt to higher and higher row
The requirement of regulation is put, and be present the problem of power consumption in electronic throttle, can be reduced in the case where not losing control effect certain
Power consumption just seem and be highly desirable.
Full close position needs the pwm signal of certain dutycycle to go controlled motor to maintain this shape for electronic throttle
State, but in this fully closed state of maintenance electronic throttle, power consumption can be reduced by reducing dutycycle；For having given
During the desired dutycycle pwm signal of final maintenance electronic throttle full-shut position, now just it is required to know electronics section
Valve is specifying whether the pwm signal lower disc amplitude of fluctuation of dutycycle meets to require, can not meet to require if valve block changes,
So the dutycycle pwm signal just needs to change, and otherwise can not just meet that control requires.But due to the variation angle of valve block
Area requirement very little, human eye is not enough to accurately judge very much, and can not provide judgment criteria, then just needs an equipment
It can accurately measure whether electronic throttle meets this requirement, and judge result, so that testing staff can be visually seen
Testing result.
The content of the invention
The technical problem to be solved in the invention there is provided the detection that a kind of electronic throttle full close position maintains state
Device and method, state lower disc change in location is maintained in order to which testing staff can accurately obtain electronic throttle full close position
Difference with require changing value scope whether be consistent, so that it is determined that whether the dutycycle pwm signal can meet control effect
On the basis of reduce energy consumption.

Above-mentioned electronic throttle full close position maintains condition checkout gear, is additionally provided with and each detection on the guidance panel
The extended terminal that controller output end in passage is connected.
Electronic throttle full close position maintain condition detection method, based on detection means realize, detection means with it is to be detected
It is connected between electronic throttle by the line trap of electronic throttle, detection means exports corresponding account in the corresponding time
The pwm signal controlled motor motion of empty ratio, closes electronic throttle to be detected, then reads electronics to be detected in the corresponding time
The positional information and record of air throttle valve block, the valve block position data of record is handled after completing to control, draws valve block
Compared with the change difference of positional information, then the scope with requiring given, so as to judge whether electronic throttle meets the requirements；
Master switch is disconnected after completing test, return spring control valve block returns to initial position.
Above-mentioned electronic throttle full close position maintains condition detection method, and detection means is sent to electronic throttle to be detected
The method of pwm signal is：Detection means can export a pwm signal compared with big space rate automatically so that electronic throttle reaches rapidly
To full close position, after maintaining a period of time, detection means is carried out to the Hall sensor return signal of electronic throttle to be detected
Processing, and now record valve block position data；Then, the dutycycle of pwm signal is gradually reduced, until the dutycycle of pwm signal
For the dutycycle of target, a period of time is maintained, the signal that detection means returns to now Hall sensor is handled and recorded
Valve block position data；Finally the scope that the data recorded twice are handled and do difference and require to give is compared, judged
This time whether the electronic throttle of detection meets the requirements.
It is as follows as a result of above technical scheme, the invention technological progress.
Electronic throttle and detection means are established contact by the present invention by plug, open switch with regard to that can control electronic throttle
Door makes valve block be in full close position, the state that the data and automatic decision valve block of automatic detection valve block position maintain, and with finger
Show whether the electronic throttle of the form displaying detection of lamp meets the requirements, so that testing staff can intuitively and accurately obtain electricity
Sub- air throttle full close position maintains whether the difference of state lower disc change in location is consistent with desired changing value scope, so as to really
Whether the fixed dutycycle pwm signal can reduce energy consumption on the basis of control effect is met, avoid because deliberately reducing energy consumption and
The situation for causing control effect to be deteriorated occurs, the good working state of effective guarantee electronic throttle.
