Description
Technical field
The present invention relates to the method for duration of the prediction between two signal edges of signals of rotational speed sensor and
Computing unit and computer program for its execution.
Background technology
Internal combustion engine of motor vehicle typically has so-called sensing wheel, and the rotating speed or crankshaft angles of internal combustion engine can be determined whereby.For
This, sensing wheel is scanned by speed probe.Because sensing wheel has a constant multiple teeth of mutual angular separation, therefore revolution speed sensing
Device provides the signal with alternately lifting/lowering signal edge.It is i.e. so-called effective by analyzing one of the two signal edge types
Signal edge, therefore rotary speed information or crankshaft angles information can be provided.
The content of the invention
According to the present invention it is proposed that being used for independent claims feature predicts two letters in signals of rotational speed sensor
The method of duration between number edge and computing unit and computer program for its execution.Advantageous embodiment
It is dependent claims and theme described below.
It is used to estimate before signals of rotational speed sensor according to the method with feature according to claim 1 of the present invention
At least one in the first duration between latter two useful signal edge, described two useful signal edges is not yet obtained
.
As formerly described, can be provided by speed probe and sensing wheel internal combustion engine rotary speed information and/or
Crankshaft angles information.But, such information typically can only be when the signal edge of the i.e. measurement or analysis finally obtained
Just provide.Can provide it is on rotating speed or crankshaft angles, than by the more specifically information obtained by useful signal edge, doing
Method be for example added between the useful signal edge of two locksteps it is a number of add equidistant angle it is micro.But for
This information after the useful signal edge finally obtained, for example must be known by the useful signal edge that finally obtains and
Duration between still none obtained next useful signal edge.
As formerly described, speed probe provides a series of lifting signal side associated with the tooth of sensing wheel
Edge, the sensing wheel can be fixedly installed on I. C. engine crankshaft and move warp by the speed probe in engine rotation
Cross.Typically, only focus on drop edge or rise edge, herein, these edges are referred to as useful signal edge.The appearance at the edge with it is right
The position of the inductive sensing gear teeth is related.Also for also obtaining trickle angle signal or rotary speed information between edges, it is possible to achieve one
Individual angle counter, it continues the micro predetermined quantity of angle of the counting between two useful signal edges.Two are effectively believed
Also referred to as increment phase or duration below interval between number edge.It is micro- that the micro generation frequency of angle now corresponds to angle
Measure quantity divided by the increment phase or duration, the increment phase or duration are only in next useful signal edge moment
By exact knowledge.Because the frequency is reset with each new signal edge for next increment, therefore can be as far as possible accurate
Predict that the time before next signal edge is reached is favourable.In this case, it is possible to crankshaft signal memory is employed, it
The history of duration obtained in the past in certain period of time is stored in, until again oldest value is override by new value.Drawn
Region in contain it is some between working cycles repeat moment variations such as air or gas mixture in cylinder internal pressure
Compressed format during contracting, they can be considered for improving the quality of duration forecast.
For the estimation in this Duration Prediction meaning, it now is possible to utilize situations below, in internal combustion engine not
Extremely similar with a succession of tooth time (duration) between cylinder or working cycles, therefore, they can pass through mutual line
Property is drawn by than calculating.
Thus, for example for duration of Δ t undeterminediDuration of Δ t so before being next toi-1With it is corresponding
By the reference duration of Δ t of a cylinder spacing or a working cyclesi-mWith Δ ti-m-1, can be with it is thus shown that one be estimated
Calculation value, using it is front and rear close to the ratio between reference duration.Therefore obtain：
。
Here, m is corresponding to the tooth pitch between cylinder or the tooth pitch for working cycles.Cylinder spacing should refer to herein
The angular separation of the time of ignition of each only cylinder of internal combustion engine, herein, working cycles formation cylinder spacing and number of cylinders multiply
Product.In the case of four cylinder engine, such as cylinder spacing is 180 degree, and working cycles are 720 degree, and this corresponds to bent axle and rotated again
Two whole circles.
But there is problems with the case, i.e. by a cylinder spacing or a job in past term of reference
The fluctuation of speed in the reference duration of circulation can not always be converted to future.First only it is related to crankshaft angles but in itself
In the case of the compression torque unrelated with rotating speed, the speed discrepancy between estimation range and term of reference is bigger, more it cannot be guaranteed that can
Conversion property.
Additionally, it is possible to also only referring to the duration history before being next to, such as ratio only referring to the first two duration
Example.Thus for example obtain：
。
In the case must be it is assumed that the rotating speed trend (rise or drop) come across in the first duration be also extended to future.
If not such case (such as near rollback point or in oscillation on bent axle near primary combustion), then can not
There can be the reliable estimation of next duration.
Now, it is assumed that the erratical fluctuations of increment phase or duration are by the power related to angle in the method proposed
Square M (φ) causes, and the torque is many times of the cylinder spacing after estimation range in term of reference, and in estimation range
It is inside identical.This is possible, because the hypothesis approx corresponds well to the rotating speed relevance with compression torque very much
Related actual state.Because independently always being needed with rotating speed for the compression of the gas flow included in a cylinder
Identical power is wanted, therefore this is also particularly useful for the moment of accelerating caused to this or retarding moment.Now it is applicable：
Wherein, J is internal combustion engine the moment of inertia, or is after variable is separated
Wherein, ω is angular speed.Obtained by the integration of the expression formula
。
If people are associated with two adjacent duration in term of reference and estimation range by this formula, now
Angle φ1And φ2As the angle corresponding to useful signal edge or reference signal edge, then according to above-mentioned hypothesis condition, this two
The moment loading of individual scope is identical.Thus obtain
,
Wherein, Δ φ between two useful signal edges of lockstep unified angle spacing in other words sensing wheel two
The spacing of individual tooth, Δ tiIt is the first duration, Δ ti-1It is the second duration, Δ ti-mIt is first to refer to duration, Δ
ti-m-1It is second to refer to the duration.Because angle separation delta φ is constant, therefore simplification is obtained：
。
That is, cause to correspond to first with reference to duration of Δ ti-mWith second with reference to duration of Δ ti-m-1Difference
Moment loading required for sensing wheel motion change can be ported to the first duration of Δ tiWith the second duration of Δ ti-1。
The method proposed is compared to the advantage of preceding method, such as in the case of rotating speed is incremented by or rotating speed successively decreases,
I.e. when term of reference and estimation range are not present in the case of identical mean speed, the prediction geared to actual circumstances can be completed.
In the case of engine acceleration, such as in the method proposed, first with reference to duration of Δ ti-mWith the second ginseng
Examine duration of Δ ti-m-1Difference be weakened in shown conversion by numerical value, that is, be applicable following formula：
。
In the case of engine retard, in the method proposed, first with reference to duration of Δ ti-mHeld with the second reference
Continuous time Δ ti-m-1Difference in the transfer by numerical value be exaggerated, that is, be applicable following formula：
。
And the relative scale of duration keeps constant in the case of preceding method, i.e., following relations are applicable：
。
That is, the method proposed consider the fluctuation of speed because the cyclic torque unrelated with rotating speed and with rotating speed into
Reduce inverse ratio.And preceding method false demonstration inverse ratio, that is, the fluctuation of speed is directly proportional to rotating speed.
Preferably, moment loading was converted to the first duration and the second duration, and way was the first duration
Determined by the second duration according to the Taylor series expansion of following formula or the formula：
。
By the solution of above-mentioned expression formula, people obtain the formula for the first duration.I.e., in this way,
First duration very simply can carry out table as the function of the second duration and the first and second reference duration
Reach and determine.
Here, the formula is advantageously identified as Taylor series expansion, herein, Taylor series expansion is using at least straight
To one-level, especially at least until two grades.Can be in the computing unit of such as control device generally because being occurred in that in the formula
The root that can only be obtained with arduously calculating, therefore above-mentioned expression formula can be simplified as more simply and rapidly transporting by Taylor series expansion
Calculate.In this regard, assuming that following hypothesis conditions are applicable：
It is approx satisfied very well in this example.People can utilize following formula in the case
Obtained for the first duration in two grades of following Taylor series expansions
。
Or preferably, the square root in formula is determined in the case where considering characteristic curve and/or look-up table.It is logical
This mode is crossed, the complicated root in computing unit can also be avoided to calculate.
Advantageously, the first duration is acquired or fixed by a still none obtained signal edge and one
Signal edge is defined, or alternatively the first duration was defined by two still none obtained signal edges.Acquired signal
Edge should refer to following signal edges herein, and it is already present in the signal obtained by speed probe, and fixed
Signal edge that signal edge can refer to estimation, especially being estimated according to the method herein proposed.So with having obtained
Signal edge first alternative in, from acquired secondary signal edge row to next signal for waiting to obtain
Therefore first duration at edge is estimated., therefore can be real because the period residing for the signal edge that waits to obtain is very short
Now very accurate estimation is predicted.In first alternative with fixed signal edge, it is from fixed
For example it is also that the secondary signal estimated herein may be used along row to the first duration for waiting next signal edge for waiting to obtain
It is estimated.In this way, for example by the way that methods described is employed many times, it is possible to achieve for the duration shortly after more
Prediction.In second alternative, for example, it can directly estimate and still be in farther the first following duration.
The duration is preferably defined by two signal edges of lockstep respectively, and refers to duration difference
Defined by two reference signal edges of lockstep.When in this way, due to two duration or with reference to continuing
Between between differ very little, therefore very accurate prediction can be realized.
In the case where considering the first duration case of estimation, advantageously on two signal sides for defining for the first duration
Rotary speed information and/or crankshaft angles information are determined between.As already described, for rotary speed information and/or crankshaft angles information, pin
A scope to still none obtained signal edge needs to estimate or predicts the corresponding duration.Because utilizing proposed side
Method allows accurately to estimate very much the duration, therefore it is perfectly suitable for determining rotary speed information and/or crankshaft angles information.
Advantageously, rotary speed information and/or crankshaft angles information are used for angle table, angle-time conversion, starter control
System rotor speed forecast and/or oil spout planning.These applications are applied in especially motor vehicle, and its needs very accurately can be by being carried
The method gone out is come the rotary speed information and/or crankshaft angles information that provide.Therefore, for typically requiring accurate bent axle resting position
Starter control, it is possible to use the described possibility that can be evaluated whether multiple duration positioned at future accurately obtains song
Axle the stopping process of IC engine up to stopping crankshaft angles.For example it can purposefully realize that future is more in the case of oil spout planning
The very fine time coordination of secondary oil spout action, especially when these oil spouts act the spaced time very in short-term.
Especially set up according to the computing unit such as device for controlling motor vehicle of the present invention on programming technique for performing this hair
Bright method.
Realize that this method is also advantageous in computer program form, because this causes very low cost, especially work as execution
Control device is also used for other tasks and thus natively sometimes.Suitable for providing the data medium of computer program especially
Magnetic memory, optical memory and electrical storage, such as hard disk, flash memory, EEPROM, DVD.By computer network (internet,
Intranet etc.) to download be feasible.
