Description
Technical field
The invention belongs to automobile control technology field, specially refer to the control of a kind of air conditioning for automobiles in the time that automobile emergency acceleratesMethod.
Background technology
Along with the theory of rise of the oil price and energy-conserving and environment-protective is rooted in the hearts of the people gradually, automobile with small output volumn with relatively low use andMaintenance cost, accepts and likes for popular gradually. But the small displacement engine that automobile with small output volumn uses, ubiquityLow speed torque is not high, and under the slow-speed of revolution, engine effective output is not high, and the power that compressor of air conditioner consumes is effectively defeatedGo out the large percentage accounting in power. Therefore automobile with small output volumn in use, acceleration while especially opening refrigeration air-conditionerCan be not enough, become the bottleneck that affects automobile with small output volumn comfort.
Summary of the invention
The object of the invention is to propose the control method of a kind of air conditioning for automobiles in the time that automobile emergency accelerates, for adding at automobile emergencyIn speed process, disconnect compressor of air conditioner relay in good time, thereby in not affecting vehicle interior temperature comfortableness, in short-termPromote the accelerating power of engine, meet the needs that automobile accelerates.
The control method of air conditioning for automobiles of the present invention in the time that automobile emergency accelerates comprises steps A: control module detects and sends out in real timeThe fuel injection pulsewidth of single atomizer in motivation, if the fuel injection pulsewidth of this atomizer all exceeds within 1 cycle of continuous NPredetermined threshold value (T), control module judges that automobile is in anxious acceleration, control module disconnects air conditioner compressed electromechanical source and holdsContinuous first scheduled time (T1), described M1 is 1 the integer of being greater than of being scheduled to; Described threshold value (T) is control moduleSearch according to automobile engine discharge capacity (L) and present engine rotating speed (N) that the form that prestores obtains.
Further, the control method of above-mentioned air conditioning for automobiles in the time that automobile emergency accelerates also comprises step B: control module existsDisconnect the fuel injection pulsewidth that detects single atomizer in engine in first scheduled time (T1) after air conditioner compressed electromechanical source,If the fuel injection pulsewidth of this atomizer all exceeds described threshold value (T) within 2 cycles of continuous N, control module isFollow-up continuous air conditioner compressed second scheduled time of electromechanical source (T2) that remains open of one scheduled time (T1), and then connectAir conditioner compressed electromechanical source, and re-execute steps A after the 3rd scheduled time (T3) of connecting air conditioner compressed electromechanical source;If the fuel injection pulsewidth of this atomizer lower than the fuel injection pulsewidth of described threshold value (T) or this atomizer not in continuous N 2In the individual cycle, all exceed described threshold value (T), control module is in first scheduled time disconnecting after air conditioner compressed electromechanical source(T1) after, connect air conditioner compressed electromechanical source, and heavy after the 3rd scheduled time (T3) of connecting air conditioner compressed electromechanical sourceNew execution step A, described M2 is 1 the integer of being greater than of being scheduled to. The setting of above-mentioned second scheduled time (T2),Fully ensured the acceleration capacity in the automobile short time, and arranging of the 3rd scheduled time (T3) can ensure air-conditioningWorking time, avoid vehicle interior temperature too high and affect comfortableness.
The computing formula of the threshold value (T) in form that prestores further, is as follows: T=K/ (L*N), described LFor automobile engine discharge capacity, described N is automobile rotational speed, and described K is predetermined constant.
Specifically, described first scheduled time (T1) is 3～12 seconds; Described second scheduled time (T2) is 1～3 seconds; Described the 3rd scheduled time (T3) is 3～6 minutes; Described M1, M2 are certain integer in 4～12Value.
Whether first the present invention judge automobile anxious accelerator by the duty that detects atomizer, and at vapourThe anxious accelerator of car breaks air conditioner compressed electromechanical source, and the power of engine consumption on compressor of air conditioner is released like thisRelease, promote in short-term the accelerating power of engine, be conducive to engine operation under desirable operating mode, promote to drive and relaxAdaptive, reduces oil consumption, meets the theme that current energy-conserving and environment-protective are large.
