With reference now to Fig. 2, it illustrates and according to the present invention for the diagnosis of electronic startup motor 110 be The general survey of system.Imagine electronic startup motor 110 to be included in the vehicle being equipped with combustion engine 120, The most electronic startup motor 110 is arranged to start combustion engine 120.Advantageously, electronic startup horse Reach 110 to be powered by battery 135.
Proposed system includes measuring cell 130 and 140 and starts motor analyser 160.Temperature is surveyed Amount element (not shown) is the most advantageously included.
Measuring cell 130 is arranged to 140 measure the technical parameter relevant with vehicle.Technology is joined Number represents that supply is to supply voltage U and the revolutions per minute of combustion engine 120 starting motor 110 RPM.In the following description, we will discuss revolutions per minute RPM of combustion engine 120 in the whole text. Because starting motor 110 and combustion engine 120 being coupled together (such as by means of so-called Bandaid gram This (Bendix) clutch), so the revolutions per minute of combustion engine 120 and startup motor 110 Revolutions per minute between be related, thus the measured revolutions per minute starting motor 110 Can revolutions per minute RPM of combustion engine 120 as proposed equally use.
Described temperature-measuring element is arranged to measure at least one temperature T relevant with vehicle.Described At least one temperature T can such as be related to the ambient temperature at vehicle, and the oil temperature in electromotor is cold But fluid temperature (F.T.), engine block temperature and/or battery temperature.It is favourable for recording more than one temperature, Because this permits a determination that vehicle is by cold start-up (all temperature are substantially identical), thermal starting (oil temperature in electromotor and cooling fluid are considerably beyond ambient temperature), or (cold at half Warm status But fluid temperature (F.T.) is considerably beyond ambient temperature, but the oil temperature in electromotor is relatively low) in started.
Start motor analyser 160 and be configured for measured technical parameter U and RPM and temperature Degree T defines the readiness S starting motor 110, and wherein readiness S is to start motor 110 The quality metric of performance.
For obtaining more preferable reliability/robustness, measuring cell 130 according to an embodiment of the invention It is arranged to measure these technical parameters, described in a certain surveying range such as 1 second with 140 During surveying range, such as, 10 independent results measured are recorded.
Alternatively, this surveying range can be adapted to by the one or more compression circulations with combustion engine 120 Property ground association, thus this surveying range represent compression circulation integer (whole number).Typically Compression circulation generally 15ms length.As the alternative that revolutions per minute RPM is asked theoretical mean Formula, in this case, it is minimum that startup motor analyser can be arranged in recording compressed circulation Revolutions per minute.It is true that have shown that startability itself is in its minimum speed.Additionally, Start motor analyser 160 can be arranged to generate in each circulation in multiple compression circulations Supply extremely starts the meansigma methods between the corresponding minimum measured supply voltage U of motor 110.
Thus, start motor analyser 160 and can be arranged to generate the quilt on whole surveying range Measure the meansigma methods of technical parameter, and, based on the supply in this surveying range to starting motor 110 Meansigma methods U of supply voltageavgAnd per minute turn of the combustion engine 120 in this surveying range Meansigma methods RPM of numberavgDefine readiness S.
In a corresponding way, temperature-measuring element is appropriately configured to measure in a certain surveying range At least one temperature T.Naturally it is configurable to generate if it is, then start motor analyser 160 The meansigma methods of at least one measured temperature T described on whole surveying range, and utilize described At least one at least one temperature being averaged is to define readiness S.
May be it is further advantageous that carry out adaptive change according to seasonal variations to start motor analyser 160 Performed diagnostic method.Such as, temperature adaptation can two steps (summer/winter) be carried out, with Multiple steps (such as less than-25 DEG C, between-25 DEG C and-20 DEG C ,-20 DEG C and-10 DEG C it Between, between-10 DEG C and ± 0 DEG C, between ± 0 DEG C and 10 DEG C, and more than 10 DEG C) enter OK, or according to defined relation constantly carry out: RPMexp=U × P1/ (T+P2), wherein RPMexp Representing intended revolutions per minute, U represents that measured supply extremely starts the supply voltage of motor 110, T represents measured temperature, and P1 and P2 is adaptation parameter.
Fig. 3 a shows the most how the first curve, signal determine preparation shape State S.This curve represents that supply extremely starts the average supply voltage U of motor 110 on the horizontal axisavg, The average minute clock revolution RPM of combustion engine 120 is represented in vertical axesavg。
According to the present embodiment of the present invention, start motor analyser 160 and be configured to, such as, if The function starting motor 110 is considered as acceptable, and readiness S classifies as OK, and such as Really readiness S is then classified as NOT if being considered as function deficiency by startup motor 110.If Measured supply voltage UavgExceed charge threshold level UthAnd the revolutions per minute measured by Tong Shi surpasses Cross revolutions per minute marginal value RPMth, then readiness S is classified as OK.
Advantageously, by revolutions per minute RPM measured by comparison and intended revolutions per minute Constantly calculate readiness S, and apply at least one threshold levels (such as, the first level generation Table acceptable startup motor function OK, and the second level is corresponding to unacceptable startup motor function NOT), such as, according to following relation:
S = 80 · R P M + N 1 ( T ) U / N 2 ( T )
Wherein,
RPM represents and starts revolutions per minute measured during attempting,
T represents measured temperature (such as feature engine temperature),
U represents and starts supply voltage measured during attempting,
N1 (T) represents revolutions per minute deviation during temperature T, and
N2 (T) represents revolutions per minute parameter during temperature T.
In above-mentioned equation, if the function starting motor is good, readiness S=80.Thus, S > 70 May correspond to acceptable startup motor function OK.On the other hand, if S < 70, then motor is started Function is considered as unacceptable NOT, therefore, should recommend to replace startup motor.
If starting two grades of condition (adaptive secondary of motor analyser 160 application adaptability Condition) will be advantageously, this depends at least one measured temperature T described.This may Requirement, when the first temperature T1, revolutions per minute must be over revolutions per minute marginal value RPMth, The degree exceeded and supply voltage UavgMore than the first control voltage Ubr1Degree relevant, wherein Ubr1≥Uth.Two grades of conditions of adaptability are advantageously inversely proportional to at least one measured temperature T described.
In order to illustrate, with reference to Fig. 3 b, wherein the second curve illustrates to start motor analyser 160 How to determine readiness S.Being similar to Fig. 3 a, this curve represents that supply is to starting horse on the horizontal axis Reach the average supply voltage U of 110avg, represent that the average minute clock of combustion engine 120 turns on a vertical axis Number RPMavg。
T1 in fig 3b, it is assumed that measured temperature T has value T2 >.Two grades of conditions of adaptability are with tested Amount temperature T is inversely proportional to it is meant that at higher temperature T, for given supply voltage UavgExcellent Select higher revolutions per minute RPMavgSo that the function starting motor 110 is considered as acceptable (and readiness S is designated the first value OK).Therefore, according to the curve in Fig. 3 b, depend on Slope steeper in two grades of conditions of temperature have than by Fig. 3 a.
In order to make the revolutions per minute at temperature T raised require tightened up, in higher temperature Under T2 > T1, second controls voltage Ubr2Also smaller value, i.e. U can be givenbr2<U br1, wherein Ubr2≥Uth。
Thus, advantageously, start motor analyser 160 and be configured to answer according to measured temperature T By two grades of conditions of adaptability so that, at higher measured temperature T2 changed proportionally, relatively Low measured supply voltage UavgMust be by exceeding revolutions per minute marginal value RPMthMeasured Revolutions per minute is mated, thus two grades of conditions of adaptability are considered to be met, and readiness S It is designated the first value OK.
On the other hand, at relatively low measured temperature T1 changed proportionally, start motor analyser 160 are advantageously arranged to specify readiness S to make of a relatively high measured supply voltage Uavg Can be by just beyond revolutions per minute marginal value RPMthMeasured revolutions per minute coupling, thus Two grades of conditions of adaptability are considered to be met, and readiness S is designated the first value OK.
If measured supply voltage UavgLess than charge threshold level Uth, then as it has been described above, can not Can determine that startup motor function.According to one embodiment of present invention, motor analyser 160 quilt is started It is configured in this case readiness S be specified the 3rd value UNDEF, represents and start motor function Can not be defined.
Start motor analyser 160 to be properly controlled with by means of being stored in memory element 165 Computer program is according to ground noted earlier driving functions, and memory element is comprised in startup motor analyser In 160 or connect with communicating with.
In a word, referring now to the preferred reality of the flow chart in Fig. 4 with the generalized approach according to the present invention Execute example and describe the method together.
In first step 405, determine and start motor and therefore, it is possible to the basis of test about activating Whether condition exists.The example of this basic condition can be the starting relevant with the alcolock in vehicle Condition must is fulfilled for, and combustion engine is not running.If basic condition applicatory is expired Foot, i.e. carries out step 410, and otherwise this process is directly entered step 455.In this step, instruction energy The ungratified message status of at least one condition of enough test start systems is generated.The operator of vehicle Also by suitably notice for meeting the relevant action of necessary condition.
