Background technology

In the manufacturing and maintenance of the product that includes closed cabin, adopted the whole bag of tricks to measure the effect that the cabin is sealed, where water or air may take place invade (or extruding).For example in vehicle, check water can not revealed and enter passenger compartment is important.Because visual inspection may be very insecure, some vehicular manufacturer utilizes spray booth that car load is carried out strong water spray can be owing to the sealing that fault or damage are arranged causes revealing with the vehicle of guaranteeing to transport from factory.Though suitable reliable of this test meeting, but it needs the workman to check the existence of water in the cabin, and has destructiveness in some sense, as in the bad vehicle of leakproofness, may causing a considerable amount of water intrusions, or in staying the vehicle in part gap because of carelessness, window or door need to spend the destruction that considerable time and materials comes remedial water to cause.In addition, the installation of spray booth and expensive in maintenance, and can not simple copy in vehicle maintenance and maintenance of equipment.

In the trial that reduces some problems of being brought by spray booth, some leak detection systems use ultrasonic sensor to reveal nondestructively to detect vehicle.The patent No. of having described such leak detection systems is 6,983,642, and name is called the United States Patent (USP) of " system and method that is used for judging automatically the closed cabin seal effectiveness " and quotes in this merging.Relevant for this, at least one ultrasonic transmitter is positioned in the passenger compartment of vehicle and launches ultrasonic energy.The level that is used to measure the approaching vehicle interior ultrasonic energy that seals at the ultrasonic sensor of outside vehicle.Ultrasonic energy can be fled from vehicle by leakage channel, and leakage channel causes outside vehicle to be positioned at or near the increase of the ultrasonic energy of leakage place.So by detecting the ultrasonic energy that increases, sensor can detect the existence of leakage.

Yet make utilizing harmless hyperacoustic sensitivity, effective and reliable leak detection systems may be difficulty and expensive.Further, expected is that the position that makes things convenient for of leak detection systems is to be positioned at or the approaching assembly line that is positioned at the vehicular manufacturer.This environment may be very noisy, and therefore, this performance to leak detection systems has a negative impact.In addition, leak detection systems and method better and cost less can be revealed by the Non-Destructive Testing closed cabin, and as the passenger compartment of vehicle, this normally is worth doing.

Embodiment

Disclosure of the present invention belongs to the system and method for leakage of the closed cabin of reliable detection such as vehicle substantially.In several embodiments of the present invention, one has the device of closed cabin, and for example vehicle (for example automobile, aircraft etc.) moves through row's ultrasonic sensor.Ultrasonic transmitter is positioned over closed cabin and emission ultrasonic energy when device moves through ultrasonic sensor.Then the leakage that detects by can't harm automatically the analysis data that obtain from ultrasonic sensor.

For convenience of explanation, after this system and a method according to the invention is being described to the leakage in detection of leaks cabin, for example passenger compartment or the storage room of the vehicles (as automobile, aircraft, steamer etc.).Yet, it will be appreciated that system and method for the present invention can be detected the leakage of the closed cabin of other types by same being used to.

Notice that system and method for the present invention may be used to test the cabin that has the sealing or do not have sealing.For example, the passenger compartment of automobile is typically packingless, even because the cabin, particularly, the sealing in cabin is certified products, normally has at least some normal leakages in passenger compartment.In such embodiments, thereby can be configured to only detect abnormal leakage that causes the cabin seal failure according to system of the present invention, this undesired be with regard to allow to surpass or than the leakage of expectation or the quantity that needs more more with regard to.For example, allowing the leakage of the intrusion of the water of unacceptable amount or gas in the vehicle is abnormal situation, yet any leakage that is designed in the cabin of sealing in another example all is abnormal.

Fig. 1 shows leak detection systems 30, and its exemplary embodiment according to the present invention tests the sealing of abnormal cabin.System 30 comprises the ultrasonic transmitter 33 that is positioned over cabin 36, and cabin 36 is the passenger compartment of vehicle (being not limited to illustrated in fig. 1) for example.Cabin 36 is moved through the ultrasonic sensor 45 of the frequency that is adjusted to transmitter 33.In an one exemplary embodiment, transmitter 33 is with about 40 KHz (kilohertz) emission ultrasonic energy.Target sensor-based system 46 detects the position of vehicle in test, and ultrasonic sensor 45 detects the ultrasonic energy of fleeing from out from cabin 36 when it moves through sensor 45.Based on sensor 45 detected ultrasonic energies, test manager 50 judges whether cabin 36 has any abnormal leakage.Further, by the data (as the data that from target sensor-based system 44 provide decision making) relevant with the position of vehicle hold 36 test that obtain from sensor 45 are provided, test manager 50 identifies the position by system's 30 detected each abnormal leakage.

Fig. 2-4 illustrates the one exemplary embodiment according to the leak detection systems 30 of exemplary embodiment of the present invention.System 30 comprises the supporting construction 52 of the row's ultrasonic sensor 45a-p that supports and be fitted thereon.The 3-D view of supporting construction 52 and the sensor 45a-p shown in Fig. 5 interrelate.In the embodiment shown in Fig. 2, supporting construction 52 is arch, and 16 ultrasonic sensor 45a-p are connected on the structure 52.Yet other shapes of structure 52 and the ultrasonic sensor 45a-p of other quantity are possible in other embodiment.

For the leakage of the passenger compartment 36 of testing vehicle 59, ultrasonic transmitter 33 is positioned in the passenger compartment 36.Further, vehicle 59 is positioned near the inside of the ultrasonic sensor 45a-p of sealing (for example under the arch that structure 52 forms), like this, if passenger compartment 36 has abnormal leakage, among the ultrasonic sensor 45a-p can detect the ultrasonic energy of fleeing from by leakage place at least.For example, vehicle 59 may be by the arch of structure 52 formation when the ultrasonic transmitter 33 emission ultrasonic energies at passenger compartment 36, and sensor 45a-p active detecting goes out ultrasonic energy simultaneously.If the passenger compartment 36 of vehicle 59 has abnormal leakage, at this moment the sensor 45a-p of approaching leakage place will detect one of them flees from out vehicle a bit by leakage channel extra ultrasonic energy probably.So it is possible detecting abnormal leakage based on these sensors 45a-p.

In this, test manager 50 (Fig. 1) is preferably interrelates with each sensor 45a-p and judges based on the data that obtain from sensor 45a-p whether vehicle 59 has any abnormal leakage in its each cabin (for example passenger compartment, main line etc.).Test manager 50 can pass through software, and hardware or their combination realize.In an one exemplary embodiment, as shown in Figure 6, test manager 50 and the method that is associated with it realize and are stored in the storer 61 of computer system 63 by software.

Notice that when carrying out test manager 50 can be stored and be transferred in any readable computer medium for the use of instruction executive component or associated, as extracting and the microprocessor of execution command by software.In the context of presents, " readable computer media " can be any mode that can comprise, store, communicate by letter, propagate or transmit for use of instruction executive component or program associated therewith.Readable computer medium can be, for example but be not limited thereto electricity, magnetic, light, electromagnetism, infrared ray, or semiconductor element or communication media.

One exemplary embodiment by the system shown in Fig. 6 63 comprises at least one conventional processing element 72, as digital signal processor (DSP) or central processing unit (CPU), it is communicated by letter via native interface 75 in system 63 and drives other element, and native interface 75 can comprise one or more buses.Further, the user of system 63 can use user input device 77, and for example, keyboard or mouse are imported data, and user's output device 79, and for example, printer or monitor can be used for output data to the user.

System 63 also comprises communication interface 83, communication interface 83 start-up systems 63 and, especially, test manager 50 can be communicated by letter with the transmitter 33 in being positioned over vehicle 59.In one embodiment, communication interface 83 can be carried out communicating wireless signals with transmitter 33, and as wireless radio frequency (RF) (RF) signal, however non-wireless signal also is possible.

Sensor interface 85 communications are connected to each ultrasonic sensor 45a-p, for example, one or more conduction connections (clearly indicating) may extend to sensor 45a-p so that numeral or analogue communication can be carried out from sensor interface 85 between interface 85 and sensor 45a-p.In another embodiment, wireless signal may be passed between interface 85 and sensor 45a-p.Test manager 50 utilizes interface 85 to receive data from sensor 45a-p, this point will after more detailed description.

System 63 also comprises I/O (I/O) interface 87 that system 63 and different external unit are communicated.For example, I/O interface 87 may communicate to connect the parts (Fig. 1) of target sensor-based system 46, this point will after more detailed description.Optical scanner 88 may be used for importing certain information to system 63, as vehicle identification information.

Shown in Fig. 2-5, supporting construction 52 has the panel 105 of a plurality of interconnection, and it is configured to form a path 10 7, and this passage extends from the bottom of the structure 52 of the side of vehicle 59.In the embodiment shown in Fig. 2-5, the part among each sensor 45a-p is positioned at path 10 7 inside.For example, Fig. 7 illustrates exemplary ultrasonic sensor 45c.Sensor 45c housing 112, it holds and is used for the circuit of position of sensing ultrasonic energy.In this, ultrasonic energy is an electric signal by converter 115 receptions and with energy conversion.Converter 115 can be installed on the housing 115 via shock absorber part 117.Converter 115 be mounted to make it the position just in time in the outside of panel 105.The circuit of housing 112 inside filters and handles the electric signal that transmits from converter 115 so that the ultrasonic energy measured value that is sensed by sensor 45c to be provided under the frequency of transmitter 33 emissions.Measure sample for each, circuit sends the designation data of measured ultrasonic energy to test manager 50.

Notice that thereby panel 105 protection converters 115 separate at least some extraneous ultrasonic energies and help the environmental acoustics at sensor and system 30 places is isolated.Sensor and ambient noise acoustics are isolated the serviceability that helps to improve sensor, particularly consider the susceptibility of sensor for the ultrasonic energy of launching from the transmitter 33 that is positioned at vehicle 59 inside.General, for the reverberation that helps prevent the ultrasonic energy in the path 10 7 influence the serviceability of sensor 45c, hope is mounted to converter 115 and makes it just in time be positioned at the outside of path 10 7 usually, also is the interior zone of panel 105.Yet in different embodiment, if necessary, the inside that converter 115 is positioned at path 10 7 is possible.It is similar or identical with sensor 45c that each sensor 45a-p possible configuration becomes, and as the combination with sensor 45c, panel 105 may help each sensor 45a-p acoustics to isolate.

Fig. 8 illustrate remove panel 105 supporting construction 52 so that the exemplary constructions of description architecture 52.As shown in Figure 8, structure 52 comprises sensor 45a-p and panel 105 inner frames 122 is installed on it, and each end of framework 122 is connected to bottom 124, and it has a flat bottom surface to be placed on the surface on ground or floor.For helping acoustics isolation structure 52 from surrounding environment, especially sensor 45a-p, bottom 124 is made up of acoustics isolated material such as rubber at the material of its lower surface (surface that promptly connects ground or floor), it can stop energy or acoustical vibration from the floor or the surface on ground be delivered to framework 122.Other elements by non-screw or opposite connected mode bottom 124 or structure 52 are connected to the ground of supporting construction 52 or the surface on floor, acoustics isolation structure 52 can by avoid introducing may cross be used for fixing structure 52 to ground or the acoustic vibration of the coupling arrangement on the surface on floor improve.Notice that conductive wire or cable make sensor 45a-p can communicate by letter with test manager 50, test manager 50 may be connected to and along framework 122 or panel 105.

Be the leakage of testing vehicle 59, the arch that vehicle 59 preferably limits by structure 2 when the 33 emission ultrasonic energies of the transmitter in the vehicle 59.In this, vehicle 9 may pass structure 52, or conveyer system, may be used to spur vehicle 59 as any traditional conveyer system on car manufacturing factory's assembly line and pass structure 52.For example, Fig. 2 illustrates the movable track 132 that is placed with vehicle 59.The motor (indicating) that track 132 can be transferred the machine system drives the arch of passing structure 52 formation with moving vehicle 59.In fact, go up (as the end) by displacement structure 52 in some points along assembly line, structure 52 may be added on the existing assembly line of vehicle manufacturer.Exemplary embodiment shown in Fig. 2 has described two tracks 132, but may use the track of other quantity in a further embodiment.For example, each tire of vehicle 59 can both be on the track independent track of system's 30 uses as long as it is enough wide.

In addition, when vehicle 59 passed structure 52, ultrasonic sensor 45a-p measured ultrasonic energy under the transmission frequency of transmitter 33.In this, each ultrasonic sensor 45a-p is transferred on the frequency of transmitter 33 so that the frequency outside the transmission frequency section all is filtered.

For example, Figure 10 illustrates when getting first sample vehicle 59 with respect to the example location of structure 52.After first sample, vehicle 59 moves further to pass structure 52, as shown in figure 11, at this moment gets second sample.In addition, vehicle 59 continues to move through structure 52 and at this moment gets appended sample.For example, Figure 12 illustrates when getting the 3rd sample vehicle 59 with respect to the example location of structure 52, and Figure 13 illustrates when getting the 4th sample vehicle 59 with respect to the example location of structure 52.Further, as described herein, vehicle 59 moves through structure 52 and can both successfully be detected along the undesired leakage on the length arbitrfary point of vehicle hold 36 like this to get each appended sample.

By following the trail of the position of vehicle 59, also be cabin 36, with respect to the position of sensor 45a-p, the position of undesired leakage can be determined.In an one exemplary embodiment, target sensor-based system 46 (Fig. 1) detects the position of vehicle 59 and the data of this position of indication is provided to test manager 50.Like this, for each sample, test manager 50 is known the position of sensor with respect to vehicle 59.In fact, just as after can more detailed description, vehicle 59 may tested sensor 45a-p with respect to the position of sensor 45a-p be used for control and when take a sample originally.In addition, be in unusual high level if detect ultrasonic energy in arbitrary sensor 45a-p sample in office, at this moment test manager 50 is determined the Position Approximate that the unusual leakage of existence occurs in the vehicle 59, and it is near the position that detects the sensor 45a-p of unusual high-caliber ultrasonic energy.

Existing multiple technologies may be used to follow the trail of the position of vehicle with respect to sensor 45a-p.In an exemplary embodiment, target sensor-based system 46 comprises sensor of interest 137 (Fig. 3) and range sensor 139 (Fig. 1).Sensor of interest 137 arrives or unusual sensing during proximity transducer 137 in the leading edge 138 (leading edge of the anterior bumper when vehicle 59 passes structure 52 on the direction shown in Fig. 2-4) of vehicle 59.For example, sensor of interest 137 may be realized in the mode of optical sensor, as infrared sensor, senses the appearance of vehicle 59 with optical means.In the embodiment shown in fig. 3, sensor of interest 137 is to receive the optical receiver of launching the light signal that comes from optical sender 141 continuously.Like this, when interrupting (just when sensor 137 stops to receive light signal from transmitter 141 emissions) sensor of interest 137, the light signal that receives just realizes that the leading edge 138 of vehicle 59 has arrived datum line 142.The sensor that detects the other types of vehicle 59 positions may be used in other embodiment.

In addition, range sensor 139 detects the motion conditions of one of them track 132, and they preferably are synchronized with the movement.For example, range sensor 139 may comprise that shaft-position encoder or other are used for the known devices of inspected object motion.In addition, based on the data that get from sensor 137 and 139, test manager 50 may be determined the position of vehicle 59 with respect to sensor 45a-p.For example, in case vehicle 59 is detected by sensor of interest 137, test manager 50 can be by measuring track 132, and how far also is vehicle has advanced since the detection of 137 pairs of leading edges 138 of sensor has begun to move the leading edge 138 of how far coming to determine vehicle 59.Notice that other technologies also can be used for detecting the position of vehicle with respect to sensor 45a-p.For example, row's optical sensor as infrared ray sensor, may be placed in along on the moving direction of vehicle 59.Like this, when vehicle 59 moved through structure 52, test manager 50 then may be determined the position of vehicle 59 to the appearance of vehicle 59 according to light sensor probes wherein.The sensor of other types and technology may be used to determine the motion of vehicle.

In an one exemplary embodiment, sensor 45a-p continuous coverage ultrasonic energy and the numerical value that measures is sent to test manager 50 in test.According to these numerical value, test manager 50 is sampled from the ultrasonic energy that sensor 45a-p measures, and this depends on the position of vehicle 59 with respect to sensor 45a-p.In this, for helping test process, sensor 45a-p is arranged to be in line, and shows as datum line 145 (Fig. 3), meets at right angles with the direction of motion of vehicle 59.Like this, suppose that among the sensor 45a-p each along the line 145 carries out its measurement.Yet at other embodiment, sensor 45a-p can be arranged to different modes.

Test manager 50 is set to take a sample at distance to a declared goal along the length of vehicle 59.For example, for ease of explanation, suppose that test manager 50 is set to get sample one time along the length of vehicle 59 per 12 inches (1 feet).In such an embodiment, in case vehicle 59 arrives datum line 145, test manager 50 can be got sample for the first time.With reference to figure 3, test manager 50 may determine when that sampling can take place by the distance (b) that deducts from sensor 45a-p (promptly from line 145) to sensor 137 distance (a) that 142 beginnings (i.e. detection from 137 pairs of vehicles 59 of sensor begins) are moved from vehicle 59 from line, in fact, test manager 50 can determine when sampling according to following formula:

a-b＝12(c-1)，

Here a and b represent with inch, and c is sampling numeral (promptly 1 represents first sample, second sample of 2 expressions, the 3rd sample of 3 expressions or the like).In addition, when vehicle 59 receiving tracks 145, above-mentioned equation is set up for first sample (being c=1).At this moment, test manager 50 is by receiving and the mode of each measured value that storage gets from each sensor 45a-p is got first sample.Notice " sample " used herein measured value definition by the ultrasonic energy that gets from each sensor 45a-p, each sample of data definition may be analyzed to be used for definite numerical value by sensor 45a-p detected ultrasonic energy when detecting sample like this.Notice that the sample data in storer 61 146 is illustrated in the sample numerical value of being stored by test manager 50 in the test process among Fig. 6.

After having got the sample first time, c increases by 1, and test manager 50 takes off a sample (sample 2) when above-mentioned equation is set up again.Like this, when the leading edge 138 of vehicle 59 move to line 145 back 12 inches the time test manager 50 get sample for the second time, when the leading edge 138 of vehicle 59 move to line 145 back 24 inches the time test manager 50 get sample three times.By continuing sampling by this way, get sample one time for per 12 inches along the length of vehicle 59.Should be noted that providing above-mentioned example to be based on is convenient to illustrative purposes, the sample of vehicle 59 extracting mode that may adopt has countless versions in other embodiments.

For instance, numerical value b may be removed such sampling just according to equation from algorithm:

a＝12(c-1)，

May change the relative position of vehicle 59 in this way for each sample.In addition, the whole length in testing vehicle 59 or cabin 39 is unnecessary, and sample separation from change be possible.For example, each sample is unnecessary after appearing at a last sample with same distance.In addition, other distances are possible in other embodiments.For example, for more accurate leak position information is provided, vehicle 59 may with approximately per 1 inch sampled, the distance between sample has just reduced like this.

In an one exemplary embodiment, the vehicle data 130 (Fig. 6) that is stored in the storer 61 of test manager 50 is associated each sensor 45a-p with each sample threshold value separately.The threshold value relevant with sensor 45a-p is to be provided with like this, if the ultrasonic energy of i.e. sensor 45a-p measurement has surpassed relevant threshold value for sample, means so to occur undesired leakage in the vehicle 59.In addition, as mentioned above, for each sample, the measurement numerical value that test manager 50 each sensor 45a-p of storage record when measuring sample.For each the such numerical value that receives from sensor 45a-p, test manager 50 is with this numerical value and the threshold relevant with sensor.If this numerical value surpasses threshold value, test manager 50 is determined abnormal leaking out in the present vehicle 59 so, the exemplary method of detected leakage more detailed description hereinafter in the positioned vehicle 59.

About this point, by the sample that sensor 45a-p extracts, each sensor 45a-p is corresponding to the different area along vehicle 59 girths for each.If it is inner or approaching with it at corresponding area that vehicle hold is revealed, sensor 45a-p may detect a large amount of ultrasonic energy of the dependent thresholds that surpasses the sensor that is limited by data 130 like this.

For instance, suppose that vehicle 59 is positioned at as shown in Figure 4 the position relevant with structure 52.In such example, regional 141a-f (Figure 14) is separately corresponding to sensor 45a-f.Particularly, regional 141a (Figure 14) is corresponding to sensor 45a, regional 141b respective sensor 45b.In addition, regional 141c respective sensor 45c, regional 141d respective sensor 45d.Further, zone 141e respective sensor 45e, zone 141f respective sensor 45f, usually, zone " corresponding to " sensor is meant if this sensor is set to have the greatest impact (with respect to the measurement of other sensors) of the ultrasonic energy that its measurement is subjected to launch from this zone.Like this, if undesired leakage appears at the specific region, so sensor passed " corresponding to " the having the greatest impact of undesired leakage place of the specific region ultrasonic energy of fleeing from out.

Have that various factors influences that ultrasonic sensor receives from the source, as undesired leakage, what of ultrasonic energy.A tangible factor is the distance of sensor from the source, and this is that particularly neighbourhood noise may cancellation or interference sections ultrasonic energy to be measured in noisy environment because ultrasonic energy can thin out when propagating.General, each sensor 45a-p compares the position and more approaches its zone accordingly with other sensors of system 30.For example, compare regional 141b position with 45c-p with other sensors 45a and approach sensor 45b most, and approach sensor 45c most with other sensors 45a-b compares regional 141c with 45d-p position.Yet, between sensor 45a-p, reaching their zones accordingly, this zone of more approaching that other sensor is placed is possible.

For at least some ultrasonic sensors, another what obvious factor from the ultrasonic energy in source that influences that ultrasonic sensor receives is the direction of sensor with respect to the source.In other words, the directivity of sensor.In this, clearly ultrasonic sensor can be with directional correlation because it to receive ultrasonic energy on certain orientation more effective.For corresponding sensor, the direction that the ultrasonic energy that relates to is here received by sensor most effectively is taken as " the maximum quantities received axle " of sensor.Like this, for the ultrasonic signal that provides, if this signal is propagated along the direction of the maximum quantities received axle of sensor, sensor generally can be measured from the ultrasonic energy of the next maximum quantity of signal.Usually, the direction of the maximum quantities received axle of the angle deviating sensor that signal is propagated is many more, and sensor is low more for the efficient of the reception of sort signal.

For instance, referring to Figure 34, any one that illustrates that exemplary sensor 45 may be used to be used as among the sensor 45a-p carried out.As shown in figure 34, sensor 45 has maximum quantities received axle 171.If this signal is propagated to sensor 45 along maximum quantities received axle 171, sensor 45 senses from the ultrasonic energy of the next maximum quantity of signal.The orientation angle that the intensity of the ultrasonic signal that receives generally moves with signal with maximum quantities received axle 171 away from the distance of signal source with sensor away from reducing.

In addition, datum line 173 is commonly defined as the half-power point boundary for sensor 45.The signal of the arbitrfary point in this zone, " receiving area " that be used as sensor that here relates to, this is limited by the half-power point boundary that line 173 is represented, this signal experiences the decay less than 3 decibels, as 45 sensings of sensor, but 3 decibels of the reception experience of the signal of any point beyond this zone or more decay.In other words, the actual signal intensity of the signal of the arbitrfary point in the receiving area of sensor that sensor 45 is measured is in 3 decibels, and the numerical value of the actual signal intensity of the signal of the arbitrfary point outside the receiving area of sensor is greater than 3 decibels.For example, transmit greater than with another angle with an angle for the measured signal intensity of signal, α is from the actual signal intensity extremely when young 3 decibel of maximum quantities received axle 171 than it.Notice that Figure 34 is the two-dimentional accompanying drawing on half-power border, this border actual in shape be three-dimensional (as circular cone).The half-power point border is known for those skilled in the art, and maximum quantities received axle 171 generally passes the center of the cone that is limited by the half-power point border.

In order to increase the susceptibility of sensor to the undesired leakage of its corresponding regional 141a-p on vehicle 59, the regional 141a-p on the pairing vehicle of sensor preferably is positioned at the receiving area inside of sensor for the sample that provides.Yet, depending on signal intensity and ambient noise level, to be positioned at outside the receiving area of sensor be possible in the zone on the corresponding vehicle 59 of sensor.

If sensor 45a-p is configured to top described each sensor 45a-p so a maximum quantities received axle 171 is arranged, as shown in figure 34, be directed for giving sample sensor 45a-p so so that separately the maximum quantities received axle 171 of sensor pass the center in the corresponding zone of sensor.Like this, for example, the maximum quantities received axle 171 of sensor 45b passes the center of regional 141b, and the maximum quantities received axle 171 of sensor 45c passes the center of regional 141c, and the like.Yet not breaking away under the above disclosed principle in other embodiments, the maximum quantities received axle 171 for special sensor 45a-p is possible towards the direction except that the corresponding regional center of sensor.

In addition, flee from if any ultrasonic energy passes undesired leakage place that provides the zone, the measurement that so corresponding sensor 45a-p is oriented to it is compared with other sensors among the sensor 45a-p and may be subjected to having the greatest impact of ultrasonic energy.In this, this zone corresponding sensor should detect the ultrasonic energy that passes undesired leakage of maximum quantity.

Further, if leaking appears in arbitrary place of regional 141a-f, threshold value preferably defines out so that corresponding at least sensor 45a-f will detect the dependent thresholds that a large amount of ultrasonic energies surpasses the sensor that is limited by data 130 so.For example, if undesired leakage in regional 141d inside, so corresponding sensor 45d preferably surveys unusual many ultrasonic energies (for example the measurement numerical value that comes from sensor 45d surpasses the dependent thresholds of sensor 45d).Like this, by the ultrasonic energy numerical value that the expression that relatively comes from sensor 45d senses, test manager 50 can be surveyed the appearance of leakage.

Notice in the undesired leakage in the place of specific regional 141a-f and may cause exceeding a plurality of threshold values.For example, it is that ultrasonic energy significantly increases that ultrasonic energy passes the aforesaid leakage possible outcome that is positioned at regional 141d inside, this is not only detected by corresponding sensor 45d, is also detected with adjacent areas 141c and the pairing sensor 45c of 141e and 45e respectively.Like this, because leakage in this example is not present in corresponding regional 141c even in fact leak, the quantity of the ultrasonic energy that sensor 45c is detected also may surpass the relevant threshold value of sensor 45c.Further, be not present in corresponding regional 141e although in fact leak, because the above-mentioned exemplary leakage at regional 141d, the quantity of the ultrasonic energy that is detected by ultrasonic sensor 45e may surpass sensor 45e dependent thresholds.

Yet possible is to leak to produce bigger influence to the sensor 45d relevant with the regional 141d that occurs leaking.Like this, if this threshold value appropriate setting in present example, as described in just as hereinafter can be more detailed, compare with 45e dependent thresholds difference separately with sensor 45c with the numerical value that gets from sensor 45c and 45e, leak the numerical value that will cause probably and surpass sensor 45d dependent thresholds in bigger degree from sensor 45d gets.Therefore, by the degree that analyte sensors 45c-e dependent thresholds is exceeded, the mensuration that test manager 50 just may be correct is leaked in regional 141d.

For example, if sample numerical value from sensor 45d and the significant difference between the sensor 45d dependent thresholds are greater than the sample numerical value of sensor 45c and 45e and the difference between sensor 45c and the 45e dependent thresholds, test manager 50 can determine that leakage only is present in regional 141d so.In an example, test manager 50 is determined number percent that each threshold value is exceeded and based on its analysis to the absolute difference between these number percents rather than sample numerical value and the threshold value.There are a variety of methods to analyze scope to the measurement of adjacent area with the undesired leakage in accurate location.

Yet, should be noted that under many circumstances, leakage will cause having only the corresponding leakage of sensor 45a-p zone to be detected the remarkable increase of ultrasonic energy quantity.In this case, need not compare the sample numerical value of adjacent area and the difference between the threshold value just can identify easily and reveal the zone.Further, it is unnecessary accurately locating leakage for test manager 50.For example, test manager 50 may point out simply which sample numerical value has exceeded their dependent thresholds, and these data may be analyzed afterwards to determine to reveal the position.In such example, test manager 50 may provide output to indicate poor between each sample numerical value and its corresponding threshold value.After this can more detailedly describe by the exemplary output that system 30 provides.

Should be noted that for a specific sample Figure 14 and only show corresponding regional 141a-f with sensor 45a-f.Similar for other zones of same sample corresponding to sensor 45g-p.For example, sensor 45g-j may be corresponding to the zone of vehicle 59 top surfaces (being roof), sensor 45k-p may corresponding to the side regions of opposite vehicle 59 shown in Figure 14.Like this, if leak out the driving side or the passenger side of present vehicle 59, perhaps in other words,, reveal so and can be detected by among the sensor 45a-p at least one at the top of vehicle 59.Notice regional 141a in fact be not as shown in Figure 14 with vehicle 59 on the part alinement.Like this, may not necessarily detect the ultrasonic energy of the enormous quantity of the transmitter 33 from the vehicle 59 corresponding to the sensor 45a of regional 141a, because regional 141a may not have leakage.Yet for the vehicle of other patterns, seat face closer particularly, regional 141a are may be on higher degree more useful for understanding the test process concerning the monitoring of regional 141a by corresponding sensor 45a like this with such vehicle alinement.

Figure 15 is exemplary illustrates each sample and the corresponding zone of sensor 45a-f that sensor 45a-f obtains when vehicle 59 passes structure 52.Particularly, Figure 15 illustrates the zone that is divided into different lines 141-156 and different rows a-f.Each zone in the identical row 141-156 is for same sample correspondence ultrasonic sensor separately, with the zone separately in the a-f of delegation for separately the corresponding same ultrasonic sensor of sample.For example, for first sample, as when vehicle 52 is in position shown in Figure 10, regional 142a-f respective sensor 45a-f separately is similar to as shown in figure 14 regional 141a-f respective sensor 45a-f.

Note taking a sample by same sensor in the different sample periods with the zone of delegation.For example, sensor 45f takes a sample at regional 142f in first sample period, takes a sample at regional 143f at second sample period sensor 45f.Further, at other sample periods sensor 45f in other arda samplings with the f of delegation.When the receiving axes 171 of corresponding sensor is just taken a sample at the respective regions with delegation during by this zone.Like this, if undesiredly leak out present specific region, so in the sample period when the quantities received axle 171 of sensor passes this zone, corresponding sensor may be passed the having the greatest impact of ultrasonic energy of leakage.For example, in the exemplary embodiment of figure 15, the quantities received axle of sensor 45d passes regional 141d (i.e. the 9th sample) in the 9th sample period.So, if undesired leaking out in the present regional 141d, this leakage should be detected when regional 141d is taken a sample by sensor 45d in the 9th sample period at least.

Notice that the example shown in Figure 15 is consistent with the methods of sampling of describing before, this method is exactly to get sample one time for per 12 inches or 1 foot along the length of vehicle 59.If this method is used for taking a sample to produce cut zone as shown in figure 15, each zone so shown in Figure 15 may be 1 foot wide (in the x-direction) each regional center is from the leading edge (n-1) of vehicle 59 foot like this, n is the respective sample data here.For example the center of regional 142a-f may be in the leading edge 138 of vehicle 59, may have 1 foot from the leading edge 138 of vehicle 59 at the center in the zone of row 143.In fact, in the embodiment show in figure 15, each sensor 45a-p preferably aims at its corresponding regional center for given sample.For example, for sample number 9, sensor 45d aims at the center of its respective regions 141d, compares access areas 141d with other ultrasonic sensors.

As mentioned above, vehicle data 130 is each sensor 45a-p association threshold value separately on the basis of each sample.In this, each threshold value preferably defines to being approximately equal to the numerical value of desired ultrasonic energy, and this ultrasonic energy is that the sensor associated 45a-p of this threshold value when tested vehicle 59 avoids abnormal leakage (sealing that is cabin 36 does not have to damage) detects.Like this, if the sample numerical value that comes from sensor associated 45a-p surpasses threshold value, vehicle 59 has abnormal leakage probably so.Further, as mentioned above, the leakage that detects may near or be positioned at the corresponding zone of sensor.For example, as mentioned above, regional 141d is associated with sensor 45d for sample number 9 (i.e. the 9th sample).So, if the numerical value that comes from sensor 45d for sample number 9 when the center of sensor 45d alignment area 141d (promptly when) surpasses the threshold value that is associated with sensor 45d of this sample, so undesired leakage probably near or be positioned at regional 141d.

Figure 16 illustrates the exemplary form of the threshold value of on each sample basis sensor 45a-p being determined by data 130 (Fig. 6).As shown in figure 16, each sensor 45a-p is for the different samples different threshold value that is associated.For example, sensor 45d is associated threshold value 10.0 for the 1st sample (being sample 1).Like this, for the 1st sample, test manager 50 will be compared by sample value and the threshold value 10.0 that sensor 45d measures.Yet for the 9th sample, test manager 50 will be compared by sample numerical value and the threshold value 15.0 that sensor 45d measures.Comparative result may indicate leakage whether to appear at the regional 141d that is associated with sensor 45d of the 9th sample.Like this, data 130 not only are associated for the 9th sample threshold value 15.0 effectively with sensor 45d, also are associated with regional 141d.In fact, if the undesired leakage of data 130 indication appear at regional 141d so this threshold value should be exceeded.

As with Figure 16 and Figure 15 more as can be seen, threshold value shows by the desired amt that does not have the ultrasonic energy that the associated sensor 45a-p that reveals vehicle 59 surveys.For example, if threshold value does not have in fact to keep the sensor 45a-p in the zone of being aligneds to be associated with vehicle hold to be measured 36 with monitoring, its threshold value is just low.As example only, the threshold value that is associated with sensor 45a is lower (as 10.0) for sample 1.In addition, sample hereto, sensor 45a be corresponding to regional 142a, its (as shown in figure 13) and vehicle 59 not and vehicle keep being aligned.Therefore, for sample 1, sensor 45a will can not detect the ultrasonic energy than higher quantity.Zone 145d and vehicle 59 maintenance being aligneds but do not keep being aligned with passenger compartment 39 to be measured.Like this, the threshold value that is associated for the corresponding sensor 45d of sample 4 regional 145d is just low, and this indicates sensor 45d will can not detect ultrasonic energy than higher quantity.

Further, for sample 6, the threshold value that sensor 45c is associated is low (as 10.0).Sample hereto, the corresponding regional 147c of sensor 45c, its (as shown in figure 15) keeps being aligneds and do not have seam at this regional 147c with passenger compartment 36.Like this, unless leak out now or approach this regional 147c, sensor 45c will can not detect the ultrasonic energy than higher quantity.If sample detects the energy (as being higher than 10.0 quantity) of high quantity by sensor 45c hereto, so test manager 50 may detect near or be positioned at the appearance of the undesired leakage of regional 147c.

Yet the threshold value that is associated with sensor 45d for sample 9 is than higher (as 15.0).Sample hereto, the corresponding regional 141d of sensor 45d, its (as shown in figure 15) keeps being aligneds with vehicle 59 jointed parts.Even do not have undesired leakage at regional 141d, also may pass seam 153 than the ultrasonic energy of higher quantity and escape from, therefore, the ratio that above-mentioned threshold value can be provided with other threshold value shown in Figure 16 are higher.In fact, in current example, the sample value of being surveyed by sensor 45d for sample 9 can be up to 15.0, and based on this sample numerical value, test manager 50 does not detect abnormal leakage.

Notice that the threshold value that is limited by data 130 may rule of thumb determine.For example, when the beginning setting threshold, known or be sure of not have the vehicle of the same kind to be measured (as model) of undesired leakage may pass structure 52, as mentioned above, at this moment the transmitter on the vehicle 33 is being launched the ultrasonic energy that senses of ultrasonic energy and sensor 45a-p sensitivity.In addition, may be used for defining threshold value for sample 1-16 thereafter by the sample numerical value that sensor 45a-p measures.If desired, can average with the definition threshold value from the next sample numerical value of a plurality of vehicles of same or similar type (as model).

In addition, for the vehicle appropriate threshold that obtains type to be measured so that how accurate test result becomes possibility, may need vehicle to dissimilar (as models) to limit different threshold values.In this, dissimilar vehicles difference in design may cause the difference of the quantity of the ultrasonic energy of normally fleeing from from the vehicle that does not have undesired leakage.For example, for given model SUV (SUV), as shown in figure 15, even along the slit 153 when not having undesired leakage, the ultrasonic energy of some may normally be fled from vehicle 59 along the slit between front door and the tail gate 153.In addition, as mentioned above, with the quantity of the expectation that is based on the ultrasonic energy of fleeing from along seam 153 along the relevant threshold value of the regional 141b-f of seam 153.Yet the regime values of the ultrasonic energy of fleeing from from the relevant seam between the front and back door of the vehicle of another model as the car type, may have a great difference than the quantity of SUV expectation.Like this for this car, compare along the threshold value of the aforementioned areas of seam 153 with SUV among Figure 15, may need to limit different threshold value along the zone of seam between the front and back door.

For better described above the explanation, with reference to Figure 17 and 18.Figure 17 illustrates the exemplary sample areas of car 159, is similar to the figure of SUV59 among Figure 15.In this, Figure 17 is exemplary illustrates the zone of the corresponding sensor 45a-f of the structure 52 of each sample got when passing to(for) automobile 159.Particularly, Figure 17 illustrates the zone that is divided into different lines 141 '-156 ' and row a '-f '.Be similar to Figure 15, the zone that is each positioned at same row 141 '-156 ' for same sample is corresponding to separately ultrasonic sensor, and for each sample each with the zone of a ' of delegation-f ' corresponding to same ultrasonic sensor.

Further, Figure 18 illustrates, and for car 159, the example table of threshold value may be limited on the basis of each sample for sensor 45a-f by data 130.Be similar to the example table that Figure 16 illustrates the threshold value of the SUV59 among Figure 15 like that.According to the figure among Figure 17, corresponding to the sensor 45d aligning seam 153 ' of regional 141d '.Like this, if undesired leakage is positioned at regional 141d ', so such leakage should be detected on sensor 45d is the data basis of sample 9 output.Can see that as Figure 17 and 18 relatively the threshold value that is used for comparing with the sample numerical value of being exported by sensor 45d is 13.0.This threshold value is different from the threshold value that is used for the zone aimed at SUV59 seam 153.In fact, by comparing Figure 16 and 18, can see for dissimilar vehicles limiting different threshold distribution that the threshold value that is used for particular vehicle like this is suitable for this type of vehicle, and this has illustrated that also a fact is that different vehicle model or types has different sealing characteristics.

Like this, if system 30 is used for SUV of test, be similar to shown in Figure 15 that, test manager 50 can be arranged to use threshold value shown in Figure 16 so.Yet, if system 30 is used to test car, being similar among Figure 17 that, test manager 50 can be arranged to use threshold value shown in Figure 180 so.In addition, vehicle data 130 can be stored the DATA DISTRIBUTION shown in Figure 16 and 18, and test manager 50 can be made suitable selection according to the type of vehicle to be measured in test.In order to make test manager 50 can make suitable selection, test manager 50 can indicate the source of type of vehicle to be measured to receive input from user or other, as VIN (VIN).

Notice that different threshold distribution can be restricted to different hierarchy levels.For example, different threshold distribution can be restricted to grade " truck ", " automobile ", " SUV ".In such example.First threshold distributes can be used for all trucies, and second threshold distribution can be used for all automobiles, and the 3rd threshold distribution can be used for all SUV.Yet in other examples, any grade can further be divided or different brackets can use jointly.Only with regard to an example, different threshold distribution can be used for different SUV, and this depends on the model of SUV to be measured.For example, first threshold distributes and can be used for Ford Explorer ^TM, second threshold distribution can be used for ToyotaPathfinder here ^TMIn addition, different threshold distribution can the mode with any needs be classified under the situation that does not exceed current disclosed principle.

Yet the identifier in order to select appropriate threshold distribution vehicle that test manager 50 receives preferably includes abundant information to determine the threshold distribution of vehicle to be measured.For example, if threshold value is classified according to 3 grades (as truck, automobile and SUV) only, the identifier of vehicle preferably indicates enough information to determine particular type (as model) truck to be measured, automobile or SUV so.Like this, the vehicle mark symbol that offers test manager preferably has enough features to distribute can make test manager 50 select appropriate threshold for vehicle to be measured.

It is unique to identify the VIN (VIN) of each vehicle from every other vehicle to notice that usually all vehicles distribute separately.In one embodiment, the VIN of vehicle to be measured is used for selecting appropriate threshold to distribute.For example, the user can import the input quantity of expression VIN.Selectable, VIN can select to obtain (as passing through photoscanner) and send test manager 50 to by electric equipment (as the scanner among Fig. 6 88).

In such an embodiment, vehicle data 130 preferably includes the enough information that makes the VIN and the appropriate threshold of test usefulness distribute and be associated.Test manager 50 uses these Information Selection appropriate threshold to distribute.For example, data 130 can comprise a row VINs, each VIN can be associated by the stand-by threshold distribution separately of the testing vehicle of VIN identification.Selectable, data 130 can be associated the vehicle model identifier with different threshold distribution.In this, very clearly the part of the VIN of vehicle just can be discerned the model of vehicle.Like this, the vehicle of same model has the identifier of the same model of the VIN that comprises them, test manager 50 can be arranged to the threshold distribution of taking out the mark symbol of vehicle and selecting to be associated with the mark symbol that takes out from VIN.Like this, same threshold distribution is used to test the vehicle of same kind, and different threshold distribution may be used to test other types.The multiple additive method of selecting the appropriate threshold distribution to be used for testing vehicle may be used in other embodiments.

Except the type fit that makes threshold distribution and vehicle to be measured, the operation of transmitter 33 also can with the type fit of vehicle to be measured, as described in hereinafter can be more detailed, to improve test result.In this, Figure 19 and 20 illustrates the transmitter 33 that meets a current disclosed embodiment.Transmitter 33 has a plurality of converter 181a-h.Each converter 181a-h is a ultrasonic energy and to compare the ultrasonic energy that emission was changed on the different directions with other converters with electric energy conversion.In the one exemplary embodiment shown in Figure 19 and 20, transmitter 33 has 8 converter 181a-h, they each comfortable each x ,-x, z, aiming and emission ultrasonic energy on-z and the y direction.The transmit direction of converter 181a-h or parallel or like this, separately perpendicular to the transmit direction of other converters.For example, the transmit direction of converter 181d and 181h is in-x direction, and it is perpendicular to converter 181a, 181b, the transmit direction of 181e and 181g (be y, z and-the z direction).Further, the direction of converter 181d and 181h is relative with the transmit direction (being the x direction) of converter 181c and 181f.Yet the converter of other numberings and other transmit directions are possible in other embodiments.

In some cases, according to the acoustic feature of vehicle 59 to be measured, all converter 181a-181e can be arranged to launch ultrasonic energy continuously with constant emissive power.As here using, " emissive power " refers to the power level of ultrasonic energy when ultrasound wave leaves the converter of launching it.The ultrasonic waves transmitted energy can increase following possibility continuously on many so different directions, if undesired leakage is promptly arranged, a large amount of ultrasonic energies will focus on and pass leakage, thereby starts the leak detection of being undertaken by test manager 50.A kind of like this " normal mode " that will ought work hereinafter for the mode of operation of transmitter 33.

Yet according to the acoustic feature of the passenger compartment 36 that is placed with transmitter 33, ultrasonic energy is possible by the inside change direction in cabin 36, and one of them a little ultrasonic energy disturbs or offset the some of them ultrasonic energy of 36 inside, cabin like this.Like this, the total amount of ultrasonic energy may reduce or reduce those should pass undesired leakage the total amount of ultrasonic energy.Therefore, the detection of undesired leakage may be more difficult.In this case, may need to reduce or eliminate the quantity of one of them converter 181a-h ultrasonic waves transmitted energy.

For example, according to the acoustic feature of vehicle 59 inside, the emissive power of one or more converter 181a-h can be adjusted (for example increase or reduce) so that better test environment to be provided.Adjustment may be permanent for the test that will carry out on particular vehicle 59, perhaps may be temporary transient.For example, the emissive power for the one or more converter 181a-h of the test period that carries out on vehicle 59 can be reduced.As example further, disturb or offset the ultrasonic energy that comes from converter 181b if determine the ultrasonic energy that comes from converter 181a, converter 181a can be undone such converter 181a and just can not launch any ultrasonic energy in test so.In other example, the emissive power of converter 181a can be according to predetermined algorithm IntermittentlyProperty reduces.For example, one or more converter 181a-h can be arranged to periodically stop to launch ultrasonic energy has only certain number (as 1) like this in any given moment converter 181a-h emission ultrasonic energy.Have or not counting method to make the emission of transmitter 33 ultrasonic energies can Be Controlled.

In an one exemplary embodiment, converter 181a-h is by emission manager 185 (Figure 21) control, and it can be by software, hardware, and perhaps their modes of combining realize.In an one exemplary embodiment, as shown in figure 21, emission manager 185 with its corresponding method, is realized in software and is stored in the storer 186 of transmitter 33.Notice emission manager 185, when in software, realizing, can any carry out to use by instruction or the relevant with it computer readable medium that can get and execute instruction such as microprocessor in be stored and transmit.

The one exemplary embodiment of the transmitter 33 shown in Figure 21 comprises at least one conventional processing element 189, as digital signal processor (DSP) or CPU (central processing unit) (CPU), they are communicated to and drive other elements in transmitter 33 via the native interface 191 that comprises one or more buses.In addition, user input device 193 as one or more buttons, for example, can be used for from the user input data of transmitter 33, and user's output device 195 as LCD (LCD), for example, can be used for output data to the user.Transmitter 33 also comprises power supply 198, as battery, for example, can provide power to transmitter element.Further, communication interface 199 can make transmitter 33 communicate by letter with system 63 shown in Figure 6.In one embodiment, communication interface 199 transmitting wireless signals are given system 63, although non-in other embodiments wireless signal may be transmitted.As shown in figure 21, converter 181a-h may be via native interface 191 other element interfaces with transmitter 33.

In order to preserve the electric power of power supply 198, emission manager 185 is arranged to make transmitter 33 to be in dormant state to begin maybe will begin up to the test of vehicle 59.Like this, emission manager 185 is because dormant state makes a plurality of element outages, as converter 181a-h.In one embodiment, the order of excitation-emission machine 33 indicates via communication interface 199 and has received the signal that test will begin in a minute, and this will more detailed hereinafter description.Like this, communication interface 199 and the being used for element of realizing launching manager 185 has enough power can make information be launched manager 185 via communication interface 199 between rest period to receive.(I think to launch manager, PLSCONFM! )

In one embodiment, test manager 50 (Fig. 6) based target sensor 137 determines when that the test of vehicle 59 should begin.In this, when sensor 137 detected the appearance of vehicle 59, test manager 50 was given transmitter 33 via interface 83 (Fig. 6) and 199 (Figure 21) emission instigation command.In response, other elements of emission manager 185 excitation-emission machines 33 will be as launching the converter 181a-h of ultrasonic energy in test.

About this, vehicle data 130 is stored in the system 63, and except storage was used for the threshold distribution of type of vehicle 59 to be measured, also the storage indication was used for the information of the emission distribution of type of vehicle 59 requirements to be measured." emission distribute " relates to the converter 181a-h desired mode of working in test.For example, as mentioned above, such its emission ultrasonic energy of emissive power that may need to adjust one or more converter 181a-h is compared different with the normal mode of transmitter 33 work.

In addition, based on the vehicle mark symbol that test manager 50 receives, test manager 50, as mentioned above, for selecting appropriate threshold to distribute by the identification vehicle 59 of vehicle data 130 indications and using this threshold distribution testing vehicle 59.Yet test manager 50 is that transmitter 33 is selected to be distributed by the suitable emission of vehicle data 130 indications with the vehicle mark symbol also.Test manager 50 indicates selecteed emission to distribute via interface 83 and 199 to transmitter 33 emission information.Based on this information, emission manager 185 control transformation device 181a-h make they in test according to selecteed emission distribution work.Therefore, converter 181a-h can select to work in which way according to the type of vehicle 59 to be measured.For example, the vehicle of all particular types (as model) can distribute tested according to different emissions according to the tested and dissimilar vehicle of same emission distribution.

Notice that the emission distribution that is used for particular vehicle 59 may be definite based on empirical data.For example, distribute in order to determine the suitable emission of particular vehicle, the vehicle of similar type may repeatedly be used different emission distribution tests by system 30 in each test.For example, all converter 181a-h can once move with continuous emission ultrasonic energy with constant emissive power in the test, and one or more converter 181a-h may at least temporarily reduce its emissive power in the operation in the other test.Then the test result of each test can analyzedly produce best result to determine which emission distributes.The emission of optimal selection distributes can be selected for same or similar vehicle.Further, vehicle data 130 can upgrade when reflecting that this selects to receive the vehicle of vehicle mark symbol identification the above-mentioned type with box lunch, and selecteed emission distributes and is used for testing this vehicle.Like this, vehicle data 130 has not only indicated the appropriate threshold that is used for each vehicle to distribute, and vehicle data 130 has also indicated the suitable emission that is used for each vehicle to distribute.

Vehicle data 130 may accord with vehicle mark with suitable emission distributed intelligence with the identical or similar method that aforesaid contact appropriate threshold distributes with vehicle mark accords with and interrelating.For example, data 130 may be stored a row VINs, and data 130 may and be used to test the vehicle emission distribution of being discerned by VIN separately with each VIN and be associated.In other words, data 130 may distribute dissimilar identifiers and be associated with different emission, and test manager 50 may take out the identifier of the type to select suitable emission distribution from VIN.It also is possible that a lot of additive methods are used to select suitable emission to distribute.

Yet what should be noted that is that the information of indicating suitable emission to distribute may be stored in other positions in other embodiments.For example, these information may be stored in transmitter 33 and make and do not need to be identified for the suitable emissions distribution of particular vehicle 59 with communicating by letter of test manager 50.Whether equally, it is possible that each vehicle is distributed with same emission, need to change between vehicle and vehicle as transmitter 33 is reused at different vehicle with regard to the emission distribution that does not need to determine transmitter 33 like this.

Disclosed a plurality of embodiment generally are described to test the undesired leakage of passenger compartment 36 in the above at present.Notice that vehicle has a more than cabin to be measured.For example, automobile has the luggage case of keeping apart with passenger compartment, may need to test the undesired leakage of luggage case except that the testing automobile passenger compartment.In such example, may all place transmitter 33 at passenger compartment and luggage case, test described herein can be used for testing this two cabins.Interchangeable, some vehicles have back seat, when it is in folded state, between passenger compartment and luggage case, produce passage, in such structure, may test by same transmitter 33 to allow two cabins in the internal flow of two of passenger compartment and luggage cases from the ultrasonic energy of individual transmitter 33.

For the several notions above of better explanation, the exemplary method of testing vehicle 59 will be described below.

For illustrative purposes, suppose that vehicle data 130 limits the form shown in Figure 16 and 18.Suppose the form of Figure 16, related to and be suitable for first model of SUV hereinafter as " SUV distribution ", the form of Figure 18, conduct " the 2nd SUV distribution " is related to and is suitable for second model of SUV hereinafter.Further supposition vehicle 59 to be measured is the SUV of first model, and it is similar to the SUV shown in Figure 15, and supposes that undesired leakage only occurs in the inside of regional 141d.Also supposition has been determined preferably to launch distribution for the SUV of first model, hereinafter as " linear frequency modulation on pulse distribution " and related to, continue the emission ultrasonic energy for the converter 181a-h of transmitter 33 exactly and make to have only among the converter 181a-h one at timely emission ultrasonic energy of any given moment.Yet, determined that best emission distributes for the SUV of second model, related to as " constant distribution " hereinafter, launch ultrasonic energy continuously simultaneously and with constant emissive power for converter 181a-h exactly.

In present example, will suppose further that the vehicle mark symbol that is used to discern vehicle 59 is its VIN, its can be from every other vehicle unique vehicle 59 that identifies.In addition, vehicle data 130 distributes VIN and is associated with the SUV shown in Figure 16, because this distribution is to be used for the preferred threshold distribution of testing vehicle 59.Like this, by analyzing vehicle data 130, test manager 50 can be selected to distribute for a SUV of vehicle 59 based on VIN, has hereinafter in more detail and describes.Distribute because this distribution is the preferred emission that is used for testing vehicle 59, vehicle data 130 also distributes VIN and is associated with linear frequency modulation on pulse.Like this, by analyzing vehicle data 130, test manager 50 can be selected to distribute for the linear frequency modulation on pulse of vehicle 59 based on VIN, has more detailed description hereinafter.Notice that vehicle data 130 may be similar other VIN are distributed with threshold value that is limited by data 130 and emission is associated, test manager 50 can may be distributed by the vehicle appropriate threshold and the emission of system's 30 tests to other in similar selection like this.

At first, transmitter 33 is calibrated and is positioned over the passenger compartment 36 of vehicle 59, square 223 and 225 as shown in figure 22.Describe in the exemplary method of calibration transmitter and the sensor document below, the application number that on October 26th, 1 proposed is 60/730,429, and the U.S. Provisional Patent Application of title " sensor calibrating system and method " is incorporated herein by reference.Square 236 as shown in figure 22 is indicated, and the emission manager 185 of transmitter 33 has been set up the communication line of communicating by letter with test manager 50.In current example, this is by being finished by the emission that the communication interface among Figure 63 83 receives can make this information at certain frequency (as in the RF scope) by communication interface shown in Figure 21 199.This information comprises the transmitter identifier, its identification transmitter 33 employed communication interfaces 199, and test manager 50 makes communication interface 199 receive such information by the transmitter identifier is included on the information of going to transmitter 33 like this.When the information that receives from transmitter 33, test manager 50 comprises the response message of above-mentioned designation of emission symbol via communication interface 83 and 199 emissions, and it can make communication interface 199 receive response messages.This information also comprises the identifier of identification communication interface 83 (Fig. 6), launches manager 185 like this and can make communication interface 83 receive these information by comprise this identifier in the information that mails to test manager 50.Thereafter, emission manager 185 may comprise the identifier of communication interface 83 in each is transmitted into the information of test manager 50, test manager may mail on the information of launching manager 185 at each and comprise the identifier of communication interface 199, thereby successfully starts the communication between test manager 50 and the emission manager 185.

Communicating to connect after the foundation between test manager 50 and emission manager 185, transmitter 33 enters dormancy, shown in square 238.This can finish by the order of sending from test manager 50 is made a response.Selectable, emission manager 185 can be arranged to make transmitter 33 enter dormant state and the order that do not need to come from test manager 50.

Shown in the square 242 as shown in figure 22, the vehicle mark of the type of identification vehicle 59 or vehicle 59 symbol (i.e. the VIN of the vehicle in present example) is received by test manager 50.For example, this VIN can be attached to vehicle 59 as current automobile assembly line is common do, photoscanner 88 (Fig. 6) can be used for this VIN is scanned into storer 61.Selectable, the vehicle mark symbol can be via user input device 77 or other equipment input systems 63.

Based on this VIN, test manager 50 selects appropriate threshold to distribute and emission distributes being used for testing vehicle 59, as square 244 is shown.In present example, vehicle data 130 is associated the mark symbol of vehicle with SUV distribution and the distribution of linear frequency modulation on pulse.Test manager 50 takes out the mark symbol of vehicle and with reference to vehicle data 130 from the VIN of vehicle.Based on vehicle data 130 and mark symbol, respectively the do for oneself threshold distribution of vehicle 59 and emission of test manager 50 distributes and selects a SUV to distribute and the distribution of linear frequency modulation on pulse.

On some points, vehicle 59 moves to structure 52, just as example, by track 132 (Fig. 2) moving vehicle towards and pass structure 52.When vehicle passes structure 52, the undesired leakage of system's 30 testing vehicles 59, shown in the square 252 of Figure 22 like that.

In this, when vehicle 59 during near structure 52, test manager 50 monitorings come from the data of the sensor of interest 137 (Fig. 3) of communicating by letter with the I/O interface 87 among Fig. 6.In case vehicle 59 arrives datum line 142 (Fig. 3) and blocks the optical signalling that is transmitted into sensor 137 by transmitter 141.Sensor 137 is to the current incident of test manager 50 reports.As response, shown as the square 263 and 266 of Figure 23, how far test manager 50 has moved from line 142 according to the leading edge 238 that the data that come from the range sensor 139 (Fig. 2) of communicating by letter with the I/O interface 87 of Fig. 6 begin to follow the trail of vehicle 59.

Same, shown in square 269, test manager 50 arrives emission manager 185 excitation-emission machines 33 by the emission instigation command.For responding this order, the element energising of emission manager 185 for using in the test.For example, emission manager 185 triggers the converter 181a-h that will use in test.In current example, converter 181a-h plants work at linear frequency modulation on pulse branch.In this, except this instigation command, the data of the emission distribution (promptly the linear frequency modulation on pulse in present example distributes) that test manager 50 emission indications are selected in the square 244 of Figure 22 are to emission manager 185, and launching manager 185 like this can be according to the operation of selecteed emission distribution control transformation device 181a-h in the test.Like this, when excitation-emission machine 33, emission manager 185 control transformation device 181a-h make these converters 181a-h according to linear frequency modulation on pulse distribution emission ultrasonic energy.Therefore, in current example, converter 181a-h continuous emission ultrasonic energy in succession makes to have only one among the converter 181a-h to launch ultrasonic energy at any given time.In other example, converter 181a-h distributes based on other emissions can Be Controlled.

In current example, suppose that test manager 50 is arranged to get sample one time from the leading edge 138 of vehicle 59 for per 12 inches or 1 foot along the length of vehicle 59.In such example, the value of test manager 50 initializing variable x is zero, shown in the square 272 of Figure 23.In this, as noted above about Fig. 3, on behalf of the leading edge 138 of vehicle 59, value a advance and crosses the distance of datum line 142, value b represent along the sensor 45a-p that lines up line from datum line 142 to datum line 145 distance.Shown in the square 275 of Figure 23, test manager 50 waits for that leading edge 138 of this expression vehicle 59 has arrived datum line 145 up to the value of the x value more than or equal to (a-b).

Notice that when vehicle 59 passes structure 52 transmitter 33 distributes according to the emission of selecting and launches ultrasonic energy.Further, ultrasonic sensor 45a-p detecting ultrasonic wave energy also provides numerical value, and the numerical value that herein relates to promptly is indicated to " sample value " of the measured energy of test manager 50.Further, shown in square 277, test manager 50 determines whether x is bigger than length over pulling faces of cou plers.Pass completely through datum line 145 (Fig. 3) up to vehicle 59, x should be littler than length over pulling faces of cou plers.Length over pulling faces of cou plers relatively can be associated by vehicle data 130 indications and with the vehicle identification symbol of vehicle 59 in square 277, and test manager 50 can obtain this numerical value automatically in test like this.

Obtain the judgement of "Yes" in square 275 after, test manager 50 is got first sample, and as square 278 indication like that, the current sample value reservation by will coming from each sensor 45a-p as sample data 146 also is stored in the storer 61 (Fig. 6).Notice that vehicle 59 is shown in Figure 10 with respect to the position of structure 52 at the first sampling.Shown in square 281, test manager 50 is compared each sample value of this first sample with the threshold value that is associated that the middle SUV who selects of square 244 (Figure 22) distributes.For example, to indicate the threshold value that is associated with sensor 45a be 10.0 to Figure 16.Like this, test manager 50 is compared this threshold value with the sample value of first sample that comes from sensor 45a, has just detected leakage as long as this sample value surpasses this threshold value.Test manager 50 adopts the threshold of the same way of first sample by each sample value and the SUV that is associated with the 45a-p of sensor separately that produces sample value are distributed other sample values.

Shown in square 284, test manager 50 determines whether detect any leakage for current sample (i.e. first sample in present example).If be found by any leakage of execution for the square 281 of current sample, test manager 50 indications are revealed and are detected so, shown in square 287.Yet, in current example, do not have leakage to be detected for current sample.Like this, should make the judgement of "No" in square 284, then test manager 50 increases by 12 (supposition a and b with inch represent) on x, and shown in square 291, so next sample will be from current sample along vehicle be removed after 12 inches of 59 the length.

After first example, cross about 12 inches of datum line 145 (Fig. 3) in case the leading edge 138 of vehicle 59 is advanced, test manager 50 is made the judgement of "Yes" again at square 275.In this, test manager 50 is got sample for the second time, shown in square 278, keeps and is stored in the storer 61 by the current sample value that will come from each sensor 45a-p as sample data 146.Notice that vehicle 59 is shown in Figure 10 with respect to the position of structure 52 when taking a sample for the second time.Shown in square 281, test manager 50 is compared each sample value of this second sample with the threshold value that is associated that the middle SUV who selects of square 244 (Figure 22) distributes.For example, to indicate the threshold value that is associated with sensor 45a be 10.0 to Figure 16.Like this, test manager 50 is compared this threshold value with the sample value of second sample that comes from sensor 45a, has just detected leakage as long as this sample value surpasses this threshold value.Test manager 50 to other sample values with to the threshold of the same way of second sample by each sample value and the SUV that is associated with the 45a-p of sensor separately that produces sample value are distributed.

Shown in square 284, test manager 50 determines whether detect any leakage for current sample (i.e. second sample in present example).If any leakage of current sample is found in the execution of square 281, test manager 50 indications are revealed and are detected so, shown in square 287.Yet, in current example, do not have leakage to be detected for current sample.Like this, should make the judgement of "No" in square 284, then test manager 50 increases by 12 (supposition a and b with inch represent) on x, and shown in square 291, so next sample will be from current sample along vehicle be removed after 12 inches of 59 the length.

In addition, square 275,277,278,281,284 and 291, the same with square 287, if suitably, when vehicle 59 passes structure 52, all rerun for each sample.Notice at the 9th sample, come from the sample value of sensor 45d and compare with this sample value in square 281 and should surpass the threshold value that is associated, because corresponding regional 141d has undesired leakage in present example.Like this, test manager 50 in square 287, indicates leakage based on the data that come from sensor 45d and is detected.

For example, test manager 287 by user's output device 79 (Fig. 6) can display message with identification sensor 45d.Selectable, test manager 50 can display message point out to be detected with the corresponding ultrasonic energy of sensor 45d high abnormal zone.For example, test manager 50 can show the graphic image that is similar to Figure 15.Can highlight show the corresponding regional 141d of sensor 45d with the ultrasonic energy that detects undesired high quantity corresponding to the regional 141d of sensor 45d.Like this, the user can know to check vehicles and 59 approaches or the possible leakage in highlighted viewing area 141d.

In addition, test manager 50 can provide for the detection of revealing one or more vision or aural alert like this workman in structure 52 environs will be warned and occur revealing.For example, Fig. 2 illustrates the lamp 322 of a pair of multicolour, and whether it is detected and radiative color based on undesired leakage.For example, detect the appearance of undesired leakage, lamp 322 can show specific color, as green, or may be closed (promptly not launching light).In case detect leakage, test manager 50 can be arranged to make the light of the other color of lamp 322 emissions, as ruddiness, is detected with the indication leakage.Fig. 2 illustrates the lamp 325 of the multiple color of another one, and whether it can be detected with the indication leakage in tested similarly manager 50 controls.Same, system 30 can comprise one or more loudspeaker (clearly not showing), test manager 50 can pass on audible alert or information to produce reaction to detecting to reveal by such loudspeaker.

In case vehicle 59 moves and crosses datum line 145 fully, the value of x should exceed the total length (calculating with inch) of vehicle 59.In case this situation takes place, test manager 50 is made the judgement of "Yes" and is made transmitter 33 enter dormancy in square 277, shown in square 333.In this, test manager 50 can be launched the emission manager 185 that makes emission manager 185 order of each element such as converter 181a-h outage be arrived transmitter 33.Like this, thus converter 181a-h stops to launch the power supply 198 that ultrasonic energy is saved transmitter.

After carrying out test process shown in Figure 23, test manager 50 if necessary, can be given the result of user report test process, shown in the square 338 of Figure 22.For example, test manager 50 can show the sample value of being taken a sample by test manager 50 via user's output device 79 (Fig. 6) in test.Selectable, these sample values can be stored in order to data-analyzing machine (clearly showing) and use in the future or analysis.For example, data-analyzing machine or user can the analyzing samples value to attempt the position of the leakage that accurately identification is detected.

Notice that if ultrasonic emitting machine 33 is operated inadequately, vehicle error ground is by the performed test of system 30 so probably.For example, if the ultrasonic emitting machine fails to launch sufficiently ultrasonic energy in test, sensor 45a-p may survey the undesired leakage of discerning vehicle interior to be measured less than enough ultrasonic energies so.When system 30 is that this problem may be thorny especially when implementing on assembly line.In this, when transmitter 33 breaks down, as the dead battery in transmitter 33, many vehicles may be by system's 30 tests before the fault of transmitter 33 is found.Again testing the vehicle that has moved apart assembly line may be difficulty and heavy.Like this, system 30 preferably is arranged to detect automatically some fault of transmitter 33 and warning is provided when detecting inefficacy.According to this warning, take correction work to reduce the influence that transmitter failure produces.For example, transmitter 33 can be replaced with exercisable transmitter fast, perhaps causes the problem of transmitter failure can be analyzed and correct.

In one embodiment, transmitter 33 comprises Launch Control Monitor 352 (Figure 21), voltage or electric current that its monitoring power supply 198 provides.In one embodiment, Launch Control Monitor 352 is by hard-wired, but may be realized by software in other embodiments at least a portion Launch Control Monitor 352.

If the monitored voltage or the electric current that are provided by power supply 198 are under the predetermined threshold, Launch Control Monitor 352 notices are launched managers 185 so.As response, emission manager 185 sends the warning that power supply 198 is about to break down.For example, emission manager 185 can pass on the sense of hearing or visual alert to be about to lose efficacy with the indication power supply.Example only, user's output device 195 can comprise light source (clearly showing), as light emitting diode (LED), when this time indication power supply 198 is about to break down.Test manager 185 can illuminate such light source to respond the above-mentioned notice from Launch Control Monitor 352.

In addition, emission manager 185 can convey a message to test manager 50 via communication interface 199 and 83 (Fig. 6).Emission manager 185 can detect transmitter to user report via user's output device 79 and be about to fault.For example, emission manager 185 can be lighted lamp 322 or 325 with special mode or color and find the transmitter possible breakdown with indication.Emission manager 185 can also pass on aural alert with the possible fault of indication transmitter.In addition, be used for warning user transmitter 33 to break down or many additive methods of being about to break down also are possible.

Should be noted that Launch Control Monitor 352 can be used to survey the transmitter failure of other types.For example, Launch Control Monitor 352 operation that can monitor converter 181a-h is broken down to detect as any one converter 181a-h.In this, for each converter 181a-h, thereby when this impedance significant change expression converter 181a-h may break down for the impedance of Launch Control Monitor 352 monitoring converter 181a-h and mensuration.It is monitored to notice that this impedance can be passed the pressure drop of converter 181a-h by measurement, supposes that the electric current that offers converter 181a-h is constant.Like this, Launch Control Monitor 352 can be arranged to measure the pressure drop of passing each converter 181a-h (difference of promptly enter the mouth voltage and outlet voltage) and with each pressure drop and certain threshold level comparison.Be lower than certain threshold level if pass the pressure drop of converter 181a-h, Launch Control Monitor 352 detects possible breakdown and the notice emission manager 185 of converter 181a-h so.Then launching manager 185 passes on warning to give the user.Notice foregoing description be used for warn power supply 198 possible breakdowns or the same or similar method that is about to break down can be used to warn converter 181a-h possible breakdown or is about to break down.The fault of other types can be detected similarly and be reported by system 30.

In addition, the position of the leakage that is detected by undesired leakage and the identification of above-mentioned detection, system 30 is for helping User Recognition and repairing vehicle and/or other have the leakage relevant issues of the product in cabin that effective instrument is provided.

Some undesired leakages may occur in the rear portion of vehicle 59 to be measured.In this case, it may be difficulty that sensor 45a-p detects this leakage, especially reveals the surface (promptly being arranged essentially parallel to the y direction) that is positioned at perpendicular.In this, energy from leakage flee from often be directivity because the energy of equivalent do not launch in all directions.For example, Figure 24 illustrates the rear portion of the exemplary vehicle 59 shown in Fig. 2-4.Suppose the undesired point 501 in 505 slit 504 along the back door now that leaks out.Like this, it is vertical substantially revealing the surface that occurs.In this case, passing a lot of ultrasonic energy that undesired leakage flees from may be towards any sensor 45a-p.In this, compare with the direction that is basically parallel to the y direction, obviously more energy will be towards the direction that is basically parallel to the x direction.Therefore not system's 30 discoveries of undesired leakage.

In order to detect the undesired leakage before or after the vehicle 59 better, system 30 can comprise that at least one is compared with other sensors 45a-p and be positioned at more direct ultrasonic sensor before or after the vehicle 59 in test.As used herein, when its maximum quantities received axle 171 has with respect to surface of vehicle near the incident angle of 90 degree sensor " more direct " towards surface of vehicle.There are a lot of methods that sensor is placed to and make it more direct towards vehicle rear.

For example, Figure 25-27 illustrates one exemplary embodiment, and wherein two sensor 45q are installed on the structure 52 in test with 45r and compare the rear portion that is positioned at more direct at least a portion towards vehicle 59 with sensor 45a-p.Like this, sensor 45q compares the ultrasonic energy that can detect the undesired leakage that is passed in these parts better with 45r with sensor 45a-p.In fact, as following will be more detailed as described in, sensor 45q and 45r can better detect the leakage on the point 501 (Figure 24) on the surface of vehicle of perpendicular.

In current example, pass the sampling of structure 52 back vehicles 59 at vehicle 59 and carry out by sensor 45q and 45r.This sampling can move past on the basis of distance of sensor of interest 137 (Fig. 3), as mentioned above at vehicle 59.Further, the sample interval cycle can be still the same when taking a sample or can be different with it by sensor 45a-p.

Figure 28 illustrates the example location of vehicle 59 when sensor 45q and 45r get sample for the first time.Figure 29 illustrates the example location of vehicle 59 when sensor 45q and 45r get next sample.Notice, in Figure 28, vehicle 59 with respect to the position of vehicle among Figure 27 59 from structure 52 move farther.Further, Figure 30 illustrates when the another one example location that moves to vehicle 59 when structure 52 farther back sensor 45q and 45r get the another one sample at vehicle.Figure 31 illustrates the other example location of vehicle 59 when sensor 45q and 45r get other sample.

In this, as shown in figure 28, sensor 45q is installed into makes its maximum quantities received axle towards the direction that is directed downwards along x, just the direction of motion of vehicle 59 in present example.Specifically, the maximum quantities received axle of sensor is towards the direction of leaving x orientation angle β.In example shown in Figure 28, β is about 45 degree, but other angles are possible in other embodiments.

Can see that as comparison diagram 28-31 vehicle 59 leaves the motion of structure 52, therefore, the different piece that sensor 45q makes the maximum quantities received axle of sensor pass vehicle 59.Particularly, the maximum quantities received axle of sensor is directed downwards along negative (-) y in the rear portion of vehicle 59 when vehicle moves away sensor 45q.In this, Figure 32 rear view that vehicle 59 is shown has shown the rear portion of vehicle.The point that point 521 expression among Figure 32 is passed when the maximum quantities received axle 517 of the position of vehicle 59 sensor 45q with respect to sensor 45q as shown in figure 28 the time.In addition, the point that passed when the maximum quantities received axle 517 of the position of vehicle 59 sensor 45q with respect to sensor 45q as shown in figure 29 time of the point among Figure 32 522 expression.In addition, the point that passed when the maximum quantities received axle 517 of the position of vehicle 59 sensor 45q with respect to sensor 45q as shown in figure 30 time of the point among Figure 32 523 expression.The point that point 524 expressions are passed when the maximum quantities received axle 517 of the position of vehicle 59 sensor 45q with respect to sensor as shown in figure 31 the time.

Pass each sample period after the structure 52 for vehicle 59, the zones of different when sensor 45q is similar to sensor 45a-p and passes structure 52 corresponding to vehicle 59 corresponding near the zones of different vehicle 59 girths.For first sample of getting by sensor 45q, sensor 45q correspondence and the regional 531q that takes a sample and pass in the maximum quantities received axle 517 of sensor.For next sample, sensor 45q correspondence and the regional 532q that takes a sample and pass in the maximum quantities received axle 517 of sensor.In addition, for the 3rd sample, sensor 45q correspondence and the regional 533q that takes a sample and pass in the maximum quantities received axle of sensor, for the 4th sample, sensor 45q is corresponding also to take a sample in regional 534q.Similarly, in three sample periods, sensor 45q is corresponding respectively and take a sample in regional 535q 546q and 537q below.

Except sensor 45r is positioned at sensor 45q to compare different z positions, sensor 45r is configured to be similar to sensor 45q.In addition, sensor 45r is placed to like this and takes a sample in regional 531r 532r, 533r, 534r, 535r, 536r and 537r respectively in its 7 sample period after vehicle 59 passes structure 52.Notice that current exemplary utilize two sensor 45q and 45r take a sample in the rear portion of vehicle 59, but the sensor of other quantity can use so also in other embodiments.

In addition, as shown in figure 31, with the sensor 45a-p more direct vertical component of ratio sensor 45q mutually towards vehicle rear.Particularly, the maximum quantities received axle of sensor 45a-p is arranged essentially parallel to the surface of vertical component, and it comprises the door 505 of vehicle rear.Like this, these the incident angle with respect to vertical component all approaches zero.Yet as shown in figure 31, the maximum quantities received axle 517 of sensor 45q is (90-β) with respect to the incident angle of the vertical component at rear portion.Like this, if β spends near 45, the incident angle of axle 517 is near 45 degree so.In addition, because ultrasonic energy seldom normally towards be parallel to the direction (for example in this example on the y direction) of revealing the surface, compare with sensor 45a-p so more pass probably reveal 501 ultrasonic energy will be towards sensor 45q this may make to become and be more prone to by sensor 45q detection of leaks 501.The direction of noticing sensor 45 may also be more towards vehicle rear off plumb zone basically, and as zone 521 and 522, this depends on the slope that these are regional.

Notice that the distance of vehicle 59 and sensor 45q should be taken into account in test on the position and direction (as β) of selecting sensor 45q.In addition, littler β generally make sensor 45q direction more towards with respect to the vertical component at least of vehicle rear and do not need to be increased in the sampling this part from the distance of sensor 45q.The direction that bigger β generally makes sensor 45q still less towards with respect to the vertical component of vehicle rear and need be increased in the sampling this part from the distance of sensor 45q.Like this, distance and direction is used alternatingly when being present in current example selection β.In at least one embodiment, β is near 45 degree, but other angles are possible in other embodiments.

In current example, test manager 50 (Fig. 6) is arranged to based on the data that come from sensor 45q and 45r to detect the undesired leakage at the rear portion of vehicle 59 based on the similar mode of undesired leakage in other zones of the Data Detection vehicle 59 that comes from sensor 45a-p with test manager 50.Like this, vehicle data 130 separately threshold value on the basis of each sample, be associated with sensor 45q and 45r.In this, in a given sample, indicate supposition comes from sensor 45q and 45r when corresponding sample areas does not have undesired leakage the expectation sample value with threshold value that sensor 45q and 45r are associated.Further, for each sample cycle after passing structure 52 at vehicle 59, test manager 50 with each sample value and the threshold ratio that is associated.If sample value surpasses the threshold value that is associated, test manager 50 has detected undesired leakage so.For example, be present in along on the point 501 in slit 504 if suppose undesired leakage, as mentioned above, so for vehicle 59 pass the 5th sample after the structure 52 come from the sample value of sensor 45q should be bigger than the threshold value that is associated of this sensor 45q.As a result, test manager 50 detects undesired leakage to respond the judgement that this sample value surpasses the threshold value that is associated.

With sensor 45q and 45r, can stop in case vehicle 59 passes the sampling of structure 52 sensor 45-p in current embodiment, sample be can't help sensor 45a-p and is read and taken a sample in the rear portion of vehicle 59 by sensor 45q and 45r like this.Yet in such an embodiment, the transmitter 33 in the vehicle 59 continues the emission ultrasonic energy to be finished up to the sampling at vehicle 59 rear portions.After this point, transmitter 33 may enter dormancy, as described above.

If the luggage case that vehicle 59 has the passenger compartment with vehicle to separate, a transmitter can be in passenger compartment, and another transmitter can be in luggage case.In such an embodiment, in case the transmitter that vehicle passes in structure 52 passenger compartments may enter dormancy, the transmitter in the luggage case can enter dormancy after the sampling at vehicle 59 rear portions is finished.It is possible that the state of the transmitter in control sampling and excitation-emission machine or the vehicle 59 has a lot of methods.

Figure 33 illustrates the exemplary installation setting of sensor 45q and 45r.Each sensor 45q and 45r are installed on the mounting bracket 555 that is attached to structure 52 in this.Further, each sensor 45q and 45r are used for when vehicle 59 passes structure 52 between two among the sensor 45a-p of vehicle 59 sampling.In this, sensor 45q is between sensor 45g and sensor 45h, and sensor 45r is between sensor 45i and 45j.As mentioned above, each sensor 45q and 45r are directed, and its maximum quantities received axle and vehicle 59 rear portions intersect when vehicle 59 moves away structure 52 like this.A lot of other mounting meanss of sensor 45q and 45r are possible in other embodiments.

The wherein part that may need in certain embodiments, movable sensor 45a-r.For example, for making sensor 45q and/or 45r be in better position to take a sample in the rear portion of vehicle 59, sensor 45q and/or 45r can be attached on the one or more displaceable elements, as one movably or the arm of robot, movable sensor 45q and/or 45r are to the position or a plurality of position that more need for the sampling in the test.For example, in case vehicle 59 passes structure 52, sensor 45q and/or 45r can be directed downwards along negative (-) y and be moved.Before next vehicle passed structure 52, sensor 45q and/or 45r can be returned to the such sensor 45q in their initial separately positions and/or 45r just can not be on the route of next vehicle.Should it is apparent that those of ordinary skills are not breaking away from the present disclosed principle basis and can make a lot of corrections to system 30 after reading these disclosures.

Well-known external noise can reduce the performance of ultrasonic sensor.For leak detection systems 30, external noise can cause any one detection of leaks mistakenly among the sensor 45a-r.In this, for any given sample, external noise may make by the quantity of a ultrasonic energy that senses among the sensor 45a-r to be increased, even sensor is exceeded vehicle 59 to be measured for the threshold value that is associated of sample and does not have undesired leakage like this.Therefore, test manager 50 may incorrectly determine that undesired leakage is present in the vehicle 59.In addition, because external noise, the ratio that this threshold value may be set up is needed higher when attempting to avoid at least some wrong leak detection.Yet, high threshold value is set may causes test manager 50 not discover at least some undesired leakages.If the influence of external noise can be alleviated, the susceptibility of the threshold value lower and/or sensor 45a-r that can be provided with can increase to reduce this probability of missing at least some undesired leakages so.

In a current disclosed embodiment.Supporting construction 52 is positioned at the space that noise reduces, and it holds supporting construction 52 and sensor 45a-r thus and stops at least some external noises to arrive sensor 45a-r.Further, in an one exemplary embodiment, noise reduce the space internal arrangement the material of the characteristic of good absorption acoustic energy arranged.Like this, the quantity by the acoustic energy of this interior volume reflection is reduced to help to reduce the quantity of the external noise in this space.At an embodiment, as described in after this can be more detailed, this space forms a vehicle 59 to be measured can be in its tunnel that pass through down.It is 60/838,237 that exemplary space is described in the application number that proposed August 17 in 2006, and name is called in the U.S. Provisional Patent Application of " system and method that detects the leakage in the closed cabin ", and it is incorporated herein by reference to.

Figure 35 illustrates the exemplary noise that may be used to hold sensor 45a-r and reduces tunnel 250.The framework 251 in the exemplary tunnel 250 of Figure 35 is general rectangular configuration, but other shapes are possible for tunnel 250 in other embodiments.In an one exemplary embodiment, the wall of framework 251 is made up of timber, but also may use the material of other types, for example, and plastics, aluminium, or steel.

There is opening 252 in tunnel 250 on one side, herein be " front ", at relative another opening 255 that has, and meanwhile herein be " back ", as shown in figure 36.In the one exemplary embodiment shown in Figure 35 and 36, opening 252 is suspended in a pair of door curtain 261 and 262 coverings on the wall 263 of framework 251, and opening 255 is suspended in a pair of door curtain 271 and 272 coverings on the wall 273 of framework 251.For illustrative purposes, Figure 37 and 38 illustrates and removes door curtain 261,262, the front and the back in 271 and 272 tunnel 250.

Door curtain 261 and 262 is attached to wall 263 by a plurality of hookups 282, as bolt, and screw or analog, thus it passes door curtain 261 and 262 and enter wall 263 door curtain 261 and 262 is fixed on the wall 263.Similarly, door curtain 271 and 272 is attached on the wall 273 by a plurality of hookups 285, as bolt, and screw or analog, thus it passes door curtain 271 and 272 and enter wall 273 door curtain 271 and 272 is fixed on the wall 273.Hookup 282 inserts the top of door curtain 261 and 262, and similarly, hookup 285 inserts the top of door curtain 271 and 272.Door curtain 261,262, an other end of 271 and 272 comprises that side and bottom and 272 are not attached to wall 263 and 273.Like this, door curtain 261,262,271 and 272 do not stop object, as vehicle, pass opening 252 and 255.

Notice that each opening 252 and 255 of current embodiment has two door curtains.In other embodiments, can use the door curtain of other quantity.For example, an independent door curtain can be used for covering any one of opening 252 or 255.Yet, can allow object between two door curtains, to pass through to each opening 252 and a plurality of door curtains of 255 usefulness, to a certain extent, may make things convenient for movement of objects to pass opening.Notice door curtain 261,262,271 and 272 help to stop at least some unnecessary external noises, and at least some embodiment in tunnel 250 can realize under 271 and 272 the situation there not being door curtain 261,262.

Each opening 252 and 255 is prescribed size can pass opening by system's 30 measured vehicle 59 like this.Further, if track 132 is used for moving vehicle 59 in test, track 132 positions are arranged to so that vehicle 59 enters tunnel 250 and leaves tunnel 250 by another opening by one in opening 252 or 255 so.Vehicle 59 when Figure 39 illustrates and leaves by opening 252 according to an one exemplary embodiment.

In addition, structure 52 preferably is positioned at 250 inside, tunnel and is held by tunnel 250, as Figure 37, shown in 38 and 40.Like this, when vehicle 59 is tested by the sensor 45a-r that is installed on structure 52, vehicle 59, the same with the sensor 45a-r of testing vehicle 59, all be the inside that is positioned at tunnel 250.Therefore, tunnel 250 protection sensor 45a-r are away from least some external noises.In this, the wall in tunnel 250 and door curtain 261,262,271 and 272 at least some external noises of reflection make it can not arrive sensor 45a-r to stop these reflection noises.

Notice door curtain 261,262,271 and 272 help protect sensor 45a-r by stoping at least some external noises to enter by space opening 252 and 255 in test.Yet, door curtain 261,262, thus 271 and 272 do not stop vehicle 59 to pass to allow each opening 252 and 255 to be bought car in installments to enter or go out.In other embodiments, the equipment of other types can replace door curtain 261,262, and 271 and 272 reach aforementioned purpose.For example, one or more moving door (not shown) may be used to cover opening 252 and/or 255.Such door can cover at least a portion of one in opening 252 or 255 and be moved from the opening automatic or manual when vehicle 59 passes such opening.

As Figure 37, shown in 38 and 41, a plurality of panels 299, it is related to as " sound panel ", adheres to and covers on the inside surface of framework 251.Sound panel 299 is made up of if any the noise elimination foam of the characteristic of good absorption voice signal material.Therefore, the environmental noise of 251 inside, space at least to a certain extent, thereby is absorbed the interference that has prevented the measurement of being finished by sensor 45a-r by sound panel 299.Like this, framework 251 has stoped at least some environmental noises to enter tunnel 250, thereby sound panel 299 absorbs the quantity that at least some environmental noises of 250 inside, tunnel have obviously reduced the environmental noise that sensor 45a-r senses.

Notice that at least some environmental noises that absorbed by sound panel 299 may be sent by the transmitter 33 in the vehicle 59 to be measured.In this, escape from and may be used to determine by any one energy that directly receives the sensor 45a-r whether vehicle 59 has any undesired leakage from vehicle 59 to be measured, such as described above.Yet the energy that some of them are escaped from from vehicle 59 may reflect the inwall that leaves tunnel 250 and be detected by one the sensor 45a-r.These emitted energies generally are unnecessary and form noise.Sound panel 299 is fled from from vehicle 59 and is not directly helped limit reflected energy by an energy that is received the sensor 45a-r by absorbing at least some.Sound panel 299 has also increased the effectiveness of tunnel protection sensor 45a-r.In this, depend on the acoustic characteristic of framework 251, at least some acoustic energy can be passed framework 251 and be entered the inside in tunnel 250.Yet sound panel 299 absorbs at least some energy rather than allows it to arrive sensor 45a-r.

In addition, according to an one exemplary embodiment testing vehicle 59, track 132 moving vehicles 59 pass opening 255 (Figure 36) and enter the interior zone in tunnel 250.When in tunnel 250, such as described above according to the undesired leakage that the measurement of sensor 45a-r comes testing vehicle 59, track 132 moving vehicles 59 pass tunnel 250 simultaneously.After the sampling that is used for testing vehicle 59 was finished, track 132 continues moving vehicles 59 to be made it pass opening 252 (Figure 35) at last 250 to go out from the tunnel.Between sampling date, tunnel 250 protection sensor 45a-r are away from the environmental noise of 250 outsides, tunnel.At least some environmental noises that sound panel 299 on tunnel 250 inwalls absorbs in the tunnel 250.Thereby sensor 45a-r can have the better measurement of noise still less.

In order further to alleviate the influence of environmental noise, each sensor 45a-r can be arranged to survey the noise generation and remove the noise that at least some detect.In this, sensor 45a-r can be arranged to the gradient of measuring-signal fluctuation, if gradient surpasses certain threshold level, has just detected the generation of noise.Therefore, if noise source produces a peak value on the signal that receives, this peak value can be detected and be eliminated.Traditional moving average filter is known to be used for noise in the erasure signal in such a way, and it can be realized by the influence that sensor 45a-r makes great efforts to reduce environmental noise.In addition, be used in combination the quantity of tunnel 250 with the environmental noise of restriction arrival sensor 45a-r, the filtering algorithm of eliminating at least a portion environmental noise that arrives sensor 45a-r may be effective especially on the susceptibility that improves signal quality and sensor 45a-r.

Figure 43 illustrates and compares the embodiment that difform tunnel 250 is arranged with the tunnel 250 shown in Figure 35.In this, the angle of the rectangle among Figure 35 is removed, and as better being illustrated among Figure 44, the outer circumference in tunnel 250 has the similar shape of outer circumference with the structure 52 shown in Fig. 2.Like this, there is edged surface 301 in tunnel 250, its each from level top 302 vertical planes 303 that extend to separately.Further, with reference to Figure 44, sensor 45a-r is attached to framework 251 and replaces on the structure of separating 52 as shown in Figure 41.Like this, framework 52 is unnecessary in the embodiment shown in Figure 44.

Yet other shapes in tunnel 250 are possible in other embodiments.For example, the cross section is arranged is semicircle or some other geometric configuratioies in tunnel 250.In other embodiments, preceding and rear wall 273 and 263 can be arranged to not have in tunnel 250.For example, embodiment can be similar to shown in Figure 43 go out except not having wall 263 and 273 or do not have door curtain 261,262,271 and 272.Like this, tunnel 250 will comprise in such an embodiment and have only sensor 45a-r to be installed on the face 301-303 of face 301-303 inside.

In addition, the face 301 with the shape that has fillet or other angles replaces the rectangular angular shown in Figure 41 to impel the more approaching vehicle 59 to be measured of sensor 45d-f and 45k-m.In fact, by the sort of cross section in structure of being similar to 52 is arranged, sensor 45a-r can be arranged in respect to the identical position of vehicle 59 just as the embodiment that is installed at sensor 45a-r on the structure 52.In addition, connect the bar of sensor 45a-r to the framework 251, the size of rope or other hookups can be selected so that sensor 45a-r place in the mode of needs.For example, as shown in figure 44, suppose that sensor 45g is connected on the framework 251 by bar 325.By selecting longer bar 325, sensor 45g can be positioned at more approaching vehicle 59 to be measured, and by selecting shorter bar 325, sensor 45g can be farther from vehicle to be measured 59.Other sensors 45a-r can be by similarly according to connecting the bar of sensor 45a-r to framework 251 with respect to the position of vehicle 59, and the length of rope or other hookups is determined.

Present disclosed content is described to the undesired leakage in the ultrasonic signal detection closed cabin.Yet, also be possible with the signal of other frequency ranges.In addition, sensor 45a-r is described as the energy of receiver/transmitter 33 emissions at this.Yet transmitter is positioned at the outside and one or more receiver of vehicle to be measured 59, and to be positioned at vehicle 59 be possible.For example, each sensor 45a-r described here can be replaced by the transmitter with different frequency scope emission ultrasonic energy.For each sample, the one or more receiver of vehicle 59 can detect the quantity of the interior ultrasonic energy of frequency range of transmitter use.If, can suppose that so undesired leakage is present in and the corresponding zone of particular transmitter in vehicle 59, being detected by the undesired high quantity of the ultrasonic energy in the frequency range of particular transmitter emission.In such example, the full test method may with described above those similar except ultrasonic energy be in vehicle 59, to launch rather than receive by equipment 45a-r by equipment 45a-r.Those skilled in the art's a lot of other modifications to system 30 after reading this part disclosure will be obvious.

Figure 45 illustrates the exemplary computer system 2400 that can be used for leak detection systems 30 (Fig. 1).Computer system 2400 comprises test manager 2450, and is similar with computer system 63 (Fig. 6) basically, and test manager 2450 is realized in software and is stored in the storer 2461 of computer system 2400 together with its relevant method.In other embodiments, test manager 2450 can hardware or hardware with realize during software combines.Briefly, the operation of each element of computer system 2400 is similar with those elements that similar relevant label is arranged shown in Figure 6 basically.

In addition, storer 2461 further comprises interface data 2405, and sample data 146 comprises a plurality of sample data collection 146a-146d, and these can further describe at this.

(Fig. 6) is similar with test manager 50, and test manager 2450 determines whether cabin 36 (Fig. 3) has any undesired leakage and identification by the position of leak detection systems 30 according to detected each the undesired leakage of ultrasonic energy that is detected by sensor 45a-p (Fig. 2).As described further on this, test manager 2450 will indicate the numerical value of the ultrasonic energy that is detected by each sensor 45a-p to compare with the threshold value of the threshold distribution of vehicle.

In an embodiment of leak detection systems 30, test manager 2450 is configured to as shown in Figure 46, be limited by interface data 2405 via user's output device 79 display graphics user interfaces (GUI) 2500.GUI2500 can more detailed description with reference to Figure 46.

In addition, test manager 2450 further is arranged to store a plurality of sample data collection 146a-146d.In this, each sample data collection 146a-146d represent to come from each sensor 45a-p (Fig. 2) and in to the test process of single unit vehicle by the sample numerical value of test manager 2450 storage.Like this, Figure 45 illustrates storer 2461 as being 4 vehicle storage sample data collection 146a-146d.Notice to be that 4 vehicle storage sample data collection 146a-146d are the purposes for exemplary illustrated, the sample data collection of other quantity may be stored among other embodiment of computer system 2400.

About Figure 46, GUI2500 comprises that exemplary vehicle manifests window 2501-2504 and can manifest at present a plurality of vehicles image 2525-2528 by the vehicle of leak detection systems 30 (Fig. 1) test with explanation.Notice that image 2525 and 2528 illustrates the opposition side view of vehicle in the exemplary test, image 2526 and 2527 respectively illustrates the top view of the vehicle in the test.Yet the different views that is illustrated in the vehicle of window 2501-2504 can be used in other embodiments, and the view shown in these is the purpose for exemplary illustrated.

Notice and manifest the explanation that window 2501-2504 can manifest any kind of a plurality of views that the vehicle under the test is shown.In this, for example, these manifest can be the digital image of actual vehicle or the profile diagram of vehicle.Notice that further these images do not need the corresponding test at present model of vehicle down.In other embodiments, different GUI are associated with the type of VIN or model/vehicle to be measured.

In an one exemplary embodiment, interface data 2405 limits a plurality of GUIs, and each GUI interrelates with different vehicle model.Further, the vehicle image that is limited by each GUI seems to be similar to the vehicle model that is associated.When the test result of particular type vehicle need show, the GUI that is associated with tested vehicle type model was used for showing test results.As mentioned above, the type model can be determined by vehicle VIN.Like this, when the test result of vehicle is shown, shown vehicle image seems similar with tested vehicle.For example, the image of the vehicle in window 2501-2504 2525-2528 can be used when the result shows for SUV.When can being shown in the result of the test of finishing dissimilar vehicles, the image of the different width of cloth shows.

Further, textbox 2509 can show that passing through of being associated with current testing vehicle manifests the identifier (VIN) of the vehicle of window 2501-2504 explanation.In addition, after the vehicle that is associated with VIN was presented at textbox 2509, textbox 2508 can show and the VIN that will be associated by the vehicle that leak detection systems 30 is tested.

GUI2500 further includes a plurality of graphics table 2505-2508 that indication comes from the zone that separates 2512 of one ultrasound samples value among the sensor 45a-p.In this, each graphics table 2505-2508 comprises the multirow 2560-2575 corresponding to a plurality of continuous samples of being finished at vehicle 59 (Fig. 2) by sensor 45a-p (Fig. 2) when passing structure 52 (Fig. 2).Further, each graphics table 2505-2508 comprises the multiple row a-p corresponding to a plurality of sensor 45a-p.Notice respectively distinguish 2512 be associated at least one threshold value shown in the threshold distribution of Figure 16.In addition, each distinguishes 2512 physical locations corresponding to vehicle.Each district seems to cover in the vehicle image corresponding to physical location in this band of position.For example, zone 2514 parts that seem to hide near the vehicle that illustrates of bottom, the side window mouth is driven in anterior centre, zone 2514, therefore, corresponding to this zone of vehicle.In addition, each zone 2412 comprises indicator, and as numerical value, indication is by the level of the measured ultrasonic energy of corresponding sensor 45a-p.

For example, show " 46 " in the zone 2514 of window 2501, it is indication when seeming to be passed structure 52 by the part of zone 2514 vehicles that cover in 59 by the ultrasonic energy of sensor 45d (Fig. 2) detection.Test manager 2450 (Figure 45) as " 46 " and in threshold distribution, in distributing is as shown in Figure 16 compared such numerical value corresponding to the manufacturing of vehicle 59 to be measured and/or the numerical value of model.

Therefore, when vehicle 59 was in test, as described herein, test manager 2450 determined whether the energy of being surveyed by sensor 45a-p (Fig. 2) surpasses the threshold value that is associated that is limited by the specific vehicle threshold distribution under the test.Further, in the embodiment of GUI2500, the indicator (not shown) that test manager 2450 may be displayed on a zone 2512 is indicated the whether test by being finished by leak detection systems 30 of a part of the vehicle under the corresponding test.In this, if vehicle may contain undesired leakage (as the threshold value that is associated that limits by threshold distribution be exceeded indicate that leakage may be present in this part or near this part), so test manager 2450 can highlight with reveal relevant specific region 2512.Like this, by simple observation display, the user can distinguish easily that vehicle region where may occur or approaching the leakage.

For example, at window 2501, test vehicle down may with the part of the vehicle of zone 2514 (for example near bottoms, anteriomedial is driven the side window mouth) correspondence.Therefore, test manager 2450 can have the leakage of the part correlation connection of the highlight inlet 2514 corresponding with vehicle under the test to give user's (not shown) indication view window 2501-2504 by highlight inlet 2514.In addition, test manager 2450 can highlight around other inlets 2515 and 2516 of inlet 2514, this similarly points out with respect to the test ultrasonic energy emission that increased of the selected threshold distribution of vehicle down.

Test manager 2450 can be indicated the ultrasonic energy that increases at form 2505-2508 by highlight zone 2512 more than threshold distribution, such as described herein.In this, if the energy that detects surpasses specific first threshold, test manager 2450 can fill up zone 2512 with particular color such as redness.Further, test manager 2450 can fill up other inlets 2512 to indicate second specific threshold value or other color such as yellow to indicate the 3rd threshold value with different colours such as green.

For example, among a plurality of embodiment of Miao Shuing, threshold distribution is described to the threshold value related with each sample value in the above.If sample value surpasses the threshold value that is associated, the detection of so undesired leakage is done.Yet in other embodiments, each sample value can be associated with a plurality of threshold values, and whether the output that system 30 provides can indicate each threshold value and be exceeded.For example, suppose that sensor 45d is for a specific sample corresponding region 2514.The sample value that comes from sensor 45d can be used to and two threshold that are associated.If this numerical value only surpasses low threshold value, the zone 2514 that test manager 2450 can highlight window 2501 makes this zone 2514 become yellow so.If two threshold values all are exceeded, the zone 2514 that test manager 2450 can highlight window 2501 makes this zone for red so.If two threshold values all are not exceeded, test manager 2450 can or can highlight should the zone be different colors without highlight zone 2514 so, as green.Like this, this zone 2514 is degree that coloud coding indicates the ultrasonic energy that the corresponding actual area of vehicle to be measured detected.For the numerical value (as the difference between the sample value that is associated or associated sample value and its relevant dependent thresholds) of the degree of replenishing or replacing colored highlight, indicating the ultrasonic energy that the actual area that is associated detects can be included in the zone 2514.Indicating a lot of additive methods of the degree of the ultrasonic energy that each sample surveys is possible in other embodiments.

As described herein, when a plurality of vehicles were tested, for example on production line, test manager 2450 limited and storage and the sample data 146 (Fig. 6) that is associated by each vehicle of revealing test macro 30 tests.Figure 47 illustrates example system 2600 and comprises leak detection systems 30 (Fig. 1) and data storage and obtain system 2602.

In such system 2600, sample data 146 comprises sample data collection 146a-146d, describes as reference Figure 45.Each sample data collection 146a-146d comprises the data that the particular measurement with by leak detection systems 30 tests next from reveal test is associated.Each sample data collection 146a-146d comprises, particularly, the data (for example threshold value that is associated of sample value and/or sample value and selected threshold distribution) of the ultrasonic energy that detected by leak detection systems 30 of indication are consistent with the physical location of relevant tested vehicle.

For example, each sample data collection 146a-146d can comprise the vehicle identification symbol of associated vehicle and the sample value of in the test of vehicle each sample being measured by sensor 45a-p (Fig. 2).In another embodiment, each sample data 146a-146d can comprise vehicle mark symbol and each sample value and the difference that is used for judging the dependent thresholds that sample value is whether excessive.In addition, any sample data collection 146a-146d can be used to analyze to obtain the sealing property of vehicle mark symbol, particularly, and for the approximate number of the leakage of the different piece of assessing vehicle.
