When user attempts activating switch under the conditions of false touch, first or wrong can be generated and touchTouch feedback to be activated in error with instruction subscriber switch.According to an embodiment, false touch activatesActivate while can including two switches.When duplicate detection to false touch, switch assembly canTo learn intended switch activator adaptively and to regulate one or more setting to allow switchActivate.When the action activated is complete, user's perceptible feedback equipment 30 can generate to userSecond or action complete feedback.When the activation of proximity switch of permission being detected, can generate3rd or correctly touch feedback.
Controller 42 processes and includes that one or more programs of program 100 are to connect based on one or moreThe activation of nearly switch 22 generates user's perceptible feedback.Controller monitoring proximity switch about one orThe activation of multiple proximity switches, and when detecting that correct touch performs dedicated action when activating.WhenDetecting when correctly activating, the correct feedback that touches can be come by any one in feedback device 30There is provided.It is sharp about the false touch of proximity transducer assembly that controller 42 also monitors proximity transducer 22Live existence and in response to this generation error touch feedback.False touch condition can be due to notClear and definite input, activates while the most two or more switches, or could be for holdingThe activation of the switch of the action of row.The feedback generated for false touch is different from for correct touchThe feedback generated so that user can distinguish the false touch of proximity switch assembly 20 and correct touchActivate.Controller 42 further determines that by when the action activating actuating of proximity switch completes, andAnd provide action to complete feedback in response to this via one or more feedback devices 30.Action completes insteadFeedback is different from false touch feedback and correctly touches feedback so that user can distinguish difference therein.
With reference to Fig. 5, illustrate the control program 100 according to an embodiment.Program 100 starts from stepRapid 102 and carry out to step 104 with monitoring for each switch proximity transducer export.Afterwards,At determination step 106, program 100 detects the activation of one or more proximity switch, and if notActivation detected, then return step 104.If be detected that the activation of one or more proximity switches,Then program 100 is carried out to determination step 108 to find indefinite input.Indefinite input is permissibleTrial including two or more proximity switches activates simultaneously.If be detected that indefinite input,Then program 100 touches feedback in step 110 generation error and then returns in step 122.If notIndefinite input detected, then program 100 is carried out to determination step 112 to determine that being exclusively used in this swashsWhether the action of the proximity switch lived allows, and if it is not allowed, then in step 110 generation errorTouch feedback and then return in step 122.Therefore, indefinite input or activation or be used forThe switch of the action being not allowed to is not regarded as the false touch activation of the action performed.ResponseIn this, touching feedback by one or more feedback device generation errors, this feedback device includes canListen audio-frequency generator 36, visual displays 38, vibration machine 40 and display lamp 42.False touchFeedback can be user's perception warning that user will be regarded as the incorrect activation of proximity switch assembly 20The feedback of type.
Activate if there is no false touch, then program 100 is carried out to step 114 to generate correct touchingTouch feedback.Correct touch feedback can be by feedback device, any one or more generate to carryFor recognized by the user can more make us pleased for what the proximity switch of the action that can perform correct was activatedThe second happy feedback.In step 116, perform the action in response to switch activator.Afterwards, program 100Carry out to step 118 to determine whether action completes, and if it is not, then return step 122.AsReally action completes, then program 100 generates action via one or more feedback devices 30 and completes feedback.It is can be recognized by the user for completing in response to the action of the activation of proximity switch that action completes to feed back3rd audible feedback of more pleasant.
According to another embodiment, correct touch can be generated and feed back to provide the feedback of multiple levels,Such as, the feedback of progression.Such as, it is in when two signaling channels for adjacent capacitance switchDuring generally similar signal level, it is provided that the false touch feedback of the first level, but,When a channel is noticeably greater than one other channel, false touch feedback can be in relative to firstSecond relatively low level of feedback.When a signaling channel is substantially greater than another to represent substantiallyDuring the correct signal of upper activation, this may indicate that operator's false touch is less serious or notable.This can aid in and provides feedback directly to user so that user is appreciated that it is considered as wrong for why inputtingBy mistake and how to change gesture with the action correctly identified.According to another example, forThe action being not allowed to, it is provided that the progression feedback of multiple levels, such as, when vehicle is at carwashWhen place user attempts to open skylight, it is provided that the first higher feedback, and when user attempts to closeWhen the skylight of closedown, it is provided that the second relatively low feedback.
According to another embodiment, it is further provided a kind of proximity switch assembly and a kind of activation connectThe method of nearly switch assembly, it is many to one or more proximity switches that the method detection is not allowed toSecondary trial is activated and is regulated one or more setting to carry based on the repeatedly trial activation detectedFor adaptive learning.This proximity switch assembly and method advantageously detect activation proximity switch repeatedlyOr the most failed trial and the most failed trial of adaptive learning and regulate one or moreArrange with the activation enabling switch.Whenever false touch condition being detected, can generate as mentioned aboveOne or more feedbacks.If the user while false touch pattern makes repeated attempts and proximity switch assemblyAlternately, then proximity switch assembly and method can regulate one or more setting to adapt to the friendship of userSignal mutually.Proximity switch assembly and method can independently regulate one or more setting to allow relativelyIndefinite mutual (such as, touch), or user can be pointed out further to carry out instructing and askingThe activation seeking any type of user is intended.The trial activation being not allowed to is referred to as mistake and touchesTouch, and can occur in the case of two or more switches activate simultaneously, two or moreThe proximity switch being probably by the finger covering of user is adjacent to two is activated relevant while individual switchThe activation field that two or more proximity transducers of connection are associated causes.Other false touch conditionsRespond including the signal that such as may be caused deficiency by the finger with bad electric conductivityThe trial of the user of the finger with protective skin cream or the finger wearing electric insulation glove activates.WithIn false touch other attempt activating can include the finger of user slowly close to proximity switch,Particularly when finger wears glove.
Activating in response to repeatedly trial false touch condition being detected, this system and method can haveRegulate one or more setting sharply and provide adaptive learning to adjust proximity switch assembly.OneIndividual or multiple setting regulation can include that regulation is for the one or more activation determining switch activatorThreshold value, regulate clear and definite signal band, letter that regulation definition signal is distributed the most between sensorsNumber ratio, the minimum-rate of regulation signal or generation time and with the activation phase determining proximity switchOther potential regulations of the setting of association.Can be adjusted for determining the various of switch activatorThe example arranged is at U.S. Patent Application Publication No. 2013/0270896 A1, entitled " proximity switchAssembly and Activiation method " patent disclosed in, above-mentioned patent is incorporated herein by.
New arranging of regulation can activate a scheduled time, such as until certain amount of company being detectedContinue and clearly activate or can for good and all be adjusted.Setting (one or more) after regulation canBe used in proximity switch associated plurality of with proximity switch assembly one or all on.OrCan be used on one group of only selected proximity switch.The setting of new regulation can apply to all users(such as, the occupant of vehicle), or different settings can be implemented for specific user.Specific occupantDetection can be based on interior vehicle sensor, key card or personal electric product.
With reference to Fig. 6 A and 6B, has an example of the false touch condition of out of order channel signal ratioFinger 58 pressing being illustrated as user is located adjacent to switch the middle proximity switch between 22A and 22C22B.Show that the finger 58 of user presses proximity switch 22B to attempt activating close to opening in fig. 6Close 22B, but all experience false touch condition whenever attempting and activating, because peak signal is relative to theThe channel ratio of the accumulation of two peak signals or all channels is insufficient to allow for activating.In this illustration,Three signal 60A-60C are connect by three be associated with corresponding three proximity switch 22A-22CNearly sensor generates.The signal being associated with each sensor is illustrated as sensor counting and becomes in timeThe function changed.When finger 58 proximity switch assembly of user, finger 58 enters and each sensorThe activation field being associated, this causes the interference to electric capacity, thus causes by shown in signal 60A-60CSensor counting increases.In this illustration, the finger 58 of user is mainly at middle proximity switchOn 22B；But, finger 58 part extends to above adjacent proximity switch 22A.As a result of which it is,Activation field makes the signal 60B being associated with the second proximity switch 22B be peak signal, and generatesThe second the biggest but relatively small peak signal 60A being associated with proximity switch 22A.WhenSecond peak signal 60A has more than second channel maximum horizontal ML2Sizable amplitude time, resistanceStop the activation to the proximity switch 22B generating peak signal 60B.When user makes repeated attempts more every timeWhen making great efforts pressing to activate same switch, the signal being associated with each sensor may become much larger,But partially due to the finger of user contacts the signaling channel letter that adjacent capacitance switch 22A is likely to occurNumber ratio is constant so that enough signals detected with it.This system and method advantageously detects mistakeRepeatedly the making repeated attempts and regulate second channel maximum horizontal ML of touch condition2Setting so as willLevel increases to second channel maximum horizontal ML after regulation2A, it is more close than to allow that this relaxes signalThe activation of switch.As a result of which it is, second channel maximum horizontal ML2ARegulation to the threshold value increased is permittedPermitted the activation that proximity switch 22B is caused due to the adaptive learning of the regulation realization by arranging.
With reference to Fig. 7, illustrate the signal response during false touch condition and its adaptive learningOne example, this example be user trial activate generate be not sufficiently strong to exceed activation threshold TSignal in the case of.Proximity switch such as proximity switch 22B is activated when user makes repeated attemptsTime, the most weak with the switch signal 60B that is associated of 22B and be illustrated as less than threshold value T.When thisWhen situation occurs, proximity switch assembly and method advantageously regulate threshold value T to the threshold reduced or after regulationValue TA, threshold value TAIt is shown in the lower value less than peak signal peak value.This allows proximity switch22B is by by relatively low threshold value T after threshold value T regulation to regulationATo relax the activation of activation threshold.
With reference to Fig. 8, illustrate the signal response during false touch condition and its adaptive learningOne example.Three the signal 60A-60C illustrated are by three the proximity switch phases discussed with Fig. 6 AThree proximity transducers of association generate.When the finger proximity switch assembly of user, finger entersThe activation field being associated with each sensor, this causes the destruction to electric capacity, thus causes such as signalSensor counting shown in 60A-60C increases.In this example, user attempts activation signal 60B instituteIn the switch shown one, signal 60B is compared to the signal being associated with two other proximity switches60A and signal 60C amplitude are bigger.Bigger signal response 60B generate compared to due to be associatedThe signal-count bigger for other signals 60A and 60C that causes alternately of switch.In this example, needStability range SR wanting peak signal 60B activates corresponding proximity switch.Peak signal 60B is shownFor having vibration at its peak amplitude, it produces the unstable signal relative to stability range SR.When operator attempts activating corresponding proximity switch, signal 60B rises, but unstable so thatSignal hunting range at its signal peak exceedes the stable model needed for the activation of detection proximity switchEnclose SR.This proximity switch assembly and method can advantageously identify this false touch condition repeatedlyOccur and be operator to intend to activate corresponding proximity switch but at the period finger that repeatedly makes repeated attemptsSwitch-pad not sufficiently stable (such as, finger rocks) or exist too much in the signalThe determination of noise.This proximity switch assembly and method can advantageously regulate stability range arrange withThe size of stability range is increased to stability range SR after regulationATo allow swashing of proximity switchLive.The stability range increased arranges SRACould be for detection activation arranges temporarily putting of requirementWidth, give tacit consent to a time period or once vehicle disable or return to after the trial of some quantity just setting upPut, or the stability range increased arranges SRAIt is probably more permanent regulation.
With reference to Fig. 9, illustrate the signal response during false touch condition and its adaptive learningOne example, wherein minimum-rate MR is carried out after activating the most failed trial of proximity switchRegulation.When peak signal advance the speed exceed minimum-rate MR time, the activation of switch can occur.In this example, the failed trial of proximity switch 22B activates and is repeated for three times, all three times of periodAttempt realizing identical peak signal.When this occurs, this proximity switch assembly and methodCan advantageously relax speed monitoring to allow to activate.This is by regulating minimum-rate MR to subtractingMinimum-rate MR after little regulationARealizing, this can allow proximity switch 22B based on signalMinimum-rate MR after the advancing the speed and regulate of 60BAThe activation of comparison.
According to an embodiment, proximity switch assembly 20 uses adaptive learning program 200, self adaptationLearning procedure 200 can be stored in the memorizer 28 of controller 24 and be performed by microprocessor 26.Adaptive learning program 200 repeatedly trial based on the proximity switch being not allowed to activates and detects mistakeMistaken touch condition and regulate one or more setting with provide allow proximity switch taste userThe switch that examination activates not enough activates the adaptive learning activated in the case of making repeated attempts.According toOne embodiment, has been illustrated in Figure 10 adaptive learning program 200.Program 200 starts from step202 and carry out to step 204 with by last time peak signal channel (LAST MAX CH) arrangeFor equal to nothing, in order to reset value.Afterwards, at determination step 206, program 200 determines whether to examineMeasure the user close to assembly to touch, and if it does not, wait the detection that user touches.The mostDetecting that user touches, program 200 just carries out to determination step 208 using that relaxes to set to determinePut or false touch condition occurs the most during parameter.If such false touch condition is not sent outRaw, then program 200 is carried out to determination step 210 to determine that use original (such as, acquiescence) is arrangedFalse touch condition whether occur, and if it is, step 240 terminate before carry out to step212 proximity switches being associated with peak signal channel (MAX CH) with activation.
If being not detected by using the false touch condition of original setting, then program 200 in step 210Carry out to step 214 to reset the false touch of enumerator labelling.False touch enumerator instruction forThe number of the false touch condition of the repetition that one switch detects.Afterwards, in step 218, activation setsPut and be reset, activate to arrange according to each embodiment and can include one or more threshold value, stablize modelEnclose, signal ratio and minimum-rate.Program 200 then advanced to step 212 before step 240 terminatesThe proximity switch being associated with peak signal channel with activation.
Return decision box 208, if be detected that use the false touch condition of the setting relaxed, then journeySequence 200 is carried out to determination step 220 to determine that whether peak signal channel is equal to last peak signalChannel, and whether the deltaT time is less than dTIME.The deltaT time is that trial swashs since for the first timeTime since work, and the dTIME time be such as five (5) seconds or more preferably at two to four (2-4)Time cycle in the range of Miao.If condition in a step 220 is not met for, then program200 are carried out to step 222 to carry out before step 228 resetting counters error touch.IfCondition in step 220 is met, then program 200 proceeds directly to step 228 to increase enumeratorFalse touch value.Hereafter, at determination step 230, program 200 determines that counters error touch value isNo more than maximum false touch value.Maximum false touch value can be the value of one or bigger and more excellentSelection of land is the value of two or bigger, and for determining the activation that makes repeated attempts of the switch being not allowed to.If counters error touch value is not more than maximum false touch, then program 200 returns to step 206,If counters error touch value is more than maximum false touch value, then program 200 proceeds to step 234One or more the setting that be associated with the determination of the activation of proximity switch is regulated to relax activation settingPut.In one example, the activation generation time cycle in two to four (2-4) seconds is attempted when three timesTime middle, regulation arranges (one or more).After relaxing activation and subprogram execution be set, program200 are carried out to determination step 236 to determine whether the peak signal being associated with proximity switch activates,And if it is, carried out to step 212 believing with peak signal to activate before step 240 terminatesThe proximity switch that road is associated.If signal does not activate, then program 200 returns to step 206.
According to an embodiment, Figure 11 illustrates that relaxing activation arranges subprogram 250.Subprogram 250Start from step 252 and proceed to determination step 254 to determine whether false touch condition W1 exists.False touch W1 condition can be less than the peak signal of threshold value, such as, result from due on fingerProtective skin cream or finger wear the finger that glove cause and have the signal of bad electric conductivity.If detectionTo false touch W1 condition, then subprogram 250 step 270 terminate before proceed to step 256 withActivation threshold is reduced the amount activated needed for switch.If being not detected by false touch W1 condition, thenSubprogram 250 proceeds to determination step 258 to determine whether false touch W2 condition to be detected.MistakeTouching W2 condition can be following condition: the signal ratio of such as peak signal and other signaling channel is tooLow, when two or more switch attempt to be simultaneously activated time above-mentioned situation it may happen that.If inspectionMeasure false touch W2 condition, then subprogram 250 proceeds to step 260 to be reduced than threshold value by signalActivate the amount needed for switch, and hereafter terminate in step 270.If being not detected by false touchW2 condition, then subprogram 250 proceeds to determination step 262 to determine whether false touch to be detectedW3 condition.When the speed increase of signal is too slow, false touch W3 condition it may happen that, work as handsRefer to slow proximity transducer assembly, particularly when glove are worn on the finger of user it may happen that believeNumber the slowest situation of speed increase.If be detected that false touch W3 condition, then subprogram 250Before step 270 terminates, proceed to step 264 activate proximity switch signal rate threshold value to be reducedRequired amount.If being not detected by false touch W3 condition, then subprogram 250 proceeds to judge stepRapid 266 to determine whether false touch W4 condition to be detected.When swinging of signal timing, false touchW4 condition is likely to occur, and when the finger of operator rocks or has too much noise in signal, signal is notStable it may happen that.If be detected that false touch W4 condition, then subprogram 250 is tied in step 270Step 268 is proceeded to stability range to be increased the amount activated needed for switch before bundle.Therefore, sub-journeySequence 250 determines one or more false touch condition, such as condition W1, W2, W3 and W4, andAnd regulate one or more setting to provide and allowing proximity switch anti-user based on attempting activationThe adaptive learning activated after multiple trial.
Therefore, proximity switch device 20 advantageously provides that the user of enhancing is mutual and user's perceptible feedbackThe most correctly activated to perform available action to user with instruction proximity switch.Switch assembly20 allow by the feedback training user use to switching device.It addition, switching device is used by givingFamily provides perceptible feedback can make less the diverting one's attention of user, and this is to have especially in motor vehicles are appliedProfit.Switch assembly 20 further provides for by adjusting when repeated multiple times false touch condition being detectedSave one or more setting to allow the adaptive learning of the activation of proximity switch and therefore to adapt to useThe interactive signal at family.
It should be appreciated that on the premise of without departing from the design of the present invention, can be to said structureMake a change and revise, and it should be further understood that such design is intended to by following powerProfit requires to cover, unless these claim is expressly stated otherwise by its word.
