With reference to Fig. 6 A and 6B, has an example of the false touch condition of out of order channel signal ratio
Finger 58 pressing being illustrated as user is located adjacent to switch the middle proximity switch between 22A and 22C
22B.Show that the finger 58 of user presses proximity switch 22B to attempt activating close to opening in fig. 6
Close 22B, but all experience false touch condition whenever attempting and activating, because peak signal is relative to the
The 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-22C
Nearly sensor generates.The signal being associated with each sensor is illustrated as sensor counting and becomes in time
The function changed.When finger 58 proximity switch assembly of user, finger 58 enters and each sensor
The activation field being associated, this causes the interference to electric capacity, thus causes by shown in signal 60A-60C
Sensor counting increases.In this illustration, the finger 58 of user is mainly at middle proximity switch
On 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 generates
The second the biggest but relatively small peak signal 60A being associated with proximity switch 22A.When
Second peak signal 60A has more than second channel maximum horizontal ML2Sizable amplitude time, resistance
Stop the activation to the proximity switch 22B generating peak signal 60B.When user makes repeated attempts more every time
When 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 occur
Number ratio is constant so that enough signals detected with it.This system and method advantageously detects mistake
Repeatedly the making repeated attempts and regulate second channel maximum horizontal ML of touch condition2Setting so as will
Level increases to second channel maximum horizontal ML after regulation2A, it is more close than to allow that this relaxes signal
The activation of switch.As a result of which it is, second channel maximum horizontal ML2ARegulation to the threshold value increased is permitted
Permitted 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 learning
One example, this example be user trial activate generate be not sufficiently strong to exceed activation threshold T
Signal in the case of.Proximity switch such as proximity switch 22B is activated when user makes repeated attempts
Time, the most weak with the switch signal 60B that is associated of 22B and be illustrated as less than threshold value T.When this
When situation occurs, proximity switch assembly and method advantageously regulate threshold value T to the threshold reduced or after regulation
Value TA, threshold value TAIt is shown in the lower value less than peak signal peak value.This allows proximity switch
22B 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 learning
One example.Three the signal 60A-60C illustrated are by three the proximity switch phases discussed with Fig. 6 A
Three proximity transducers of association generate.When the finger proximity switch assembly of user, finger enters
The activation field being associated with each sensor, this causes the destruction to electric capacity, thus causes such as signal
Sensor counting shown in 60A-60C increases.In this example, user attempts activation signal 60B institute
In the switch shown one, signal 60B is compared to the signal being associated with two other proximity switches
60A and signal 60C amplitude are bigger.Bigger signal response 60B generate compared to due to be associated
The signal-count bigger for other signals 60A and 60C that causes alternately of switch.In this example, need
Stability range SR wanting peak signal 60B activates corresponding proximity switch.Peak signal 60B is shown
For 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 that
Signal hunting range at its signal peak exceedes the stable model needed for the activation of detection proximity switch
Enclose SR.This proximity switch assembly and method can advantageously identify this false touch condition repeatedly
Occur and be operator to intend to activate corresponding proximity switch but at the period finger that repeatedly makes repeated attempts
Switch-pad not sufficiently stable (such as, finger rocks) or exist too much in the signal
The determination of noise.This proximity switch assembly and method can advantageously regulate stability range arrange with
The size of stability range is increased to stability range SR after regulationATo allow swashing of proximity switch
Live.The stability range increased arranges SRACould be for detection activation arranges temporarily putting of requirement
Width, give tacit consent to a time period or once vehicle disable or return to after the trial of some quantity just setting up

With reference to Fig. 9, illustrate the signal response during false touch condition and its adaptive learning
One example, wherein minimum-rate MR is carried out after activating the most failed trial of proximity switch
Regulation.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 period
Attempt realizing identical peak signal.When this occurs, this proximity switch assembly and method
Can advantageously relax speed monitoring to allow to activate.This is by regulating minimum-rate MR to subtracting
Minimum-rate MR after little regulationARealizing, this can allow proximity switch 22B based on signal
Minimum-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 adaptation
Learning 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 mistake
Mistaken touch condition and regulate one or more setting with provide allow proximity switch taste user
The switch that examination activates not enough activates the adaptive learning activated in the case of making repeated attempts.According to
One embodiment, has been illustrated in Figure 10 adaptive learning program 200.Program 200 starts from step
202 and carry out to step 204 with by last time peak signal channel (LAST MAX CH) arrange
For equal to nothing, in order to reset value.Afterwards, at determination step 206, program 200 determines whether to examine
Measure the user close to assembly to touch, and if it does not, wait the detection that user touches.The most
Detecting that user touches, program 200 just carries out to determination step 208 using that relaxes to set to determine
Put or false touch condition occurs the most during parameter.If such false touch condition is not sent out
Raw, then program 200 is carried out to determination step 210 to determine that use original (such as, acquiescence) is arranged
False touch condition whether occur, and if it is, step 240 terminate before carry out to step
212 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 210
Carry out to step 214 to reset the false touch of enumerator labelling.False touch enumerator instruction for
The number of the false touch condition of the repetition that one switch detects.Afterwards, in step 218, activation sets
Put and be reset, activate to arrange according to each embodiment and can include one or more threshold value, stablize model
Enclose, signal ratio and minimum-rate.Program 200 then advanced to step 212 before step 240 terminates
The 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 journey
Sequence 200 is carried out to determination step 220 to determine that whether peak signal channel is equal to last peak signal
Channel, and whether the deltaT time is less than dTIME.The deltaT time is that trial swashs since for the first time
Time 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 program
200 are carried out to step 222 to carry out before step 228 resetting counters error touch.If
Condition in step 220 is met, then program 200 proceeds directly to step 228 to increase enumerator
False touch value.Hereafter, at determination step 230, program 200 determines that counters error touch value is
No more than maximum false touch value.Maximum false touch value can be the value of one or bigger and more excellent
Selection 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 234
One or more the setting that be associated with the determination of the activation of proximity switch is regulated to relax activation setting
Put.In one example, the activation generation time cycle in two to four (2-4) seconds is attempted when three times
Time middle, regulation arranges (one or more).After relaxing activation and subprogram execution be set, program
200 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 terminates
The 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 250
Start 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 finger
Protective skin cream or finger wear the finger that glove cause and have the signal of bad electric conductivity.If detection
To false touch W1 condition, then subprogram 250 step 270 terminate before proceed to step 256 with
Activation threshold is reduced the amount activated needed for switch.If being not detected by false touch W1 condition, then
Subprogram 250 proceeds to determination step 258 to determine whether false touch W2 condition to be detected.Mistake
Touching W2 condition can be following condition: the signal ratio of such as peak signal and other signaling channel is too
Low, when two or more switch attempt to be simultaneously activated time above-mentioned situation it may happen that.If inspection
Measure false touch W2 condition, then subprogram 250 proceeds to step 260 to be reduced than threshold value by signal
Activate the amount needed for switch, and hereafter terminate in step 270.If being not detected by false touch
W2 condition, then subprogram 250 proceeds to determination step 262 to determine whether false touch to be detected
W3 condition.When the speed increase of signal is too slow, false touch W3 condition it may happen that, work as hands
Refer to slow proximity transducer assembly, particularly when glove are worn on the finger of user it may happen that believe
Number the slowest situation of speed increase.If be detected that false touch W3 condition, then subprogram 250
Before step 270 terminates, proceed to step 264 activate proximity switch signal rate threshold value to be reduced
Required amount.If being not detected by false touch W3 condition, then subprogram 250 proceeds to judge step
Rapid 266 to determine whether false touch W4 condition to be detected.When swinging of signal timing, false touch
W4 condition is likely to occur, and when the finger of operator rocks or has too much noise in signal, signal is not
Stable it may happen that.If be detected that false touch W4 condition, then subprogram 250 is tied in step 270
Step 268 is proceeded to stability range to be increased the amount activated needed for switch before bundle.Therefore, sub-journey
