Wherein, the corresponding automobile dome light in each touch area.
Wherein, with reference to figure 2, be described below in detail and determine that the detection method principle of position of touch is as follows:
This method is sent by the circulation of wheel current control infrared receiving/transmission pipe 101 and 102, receiving infrared-ray, to detect the distance of barrier in real time.When having touch control operation in the first shown in fig. 2 touch area 103, suppose that touch point is number in the figure P place, then namely this method can detect that the barrier at P place, touch point is respectively apart from the distance of infrared receiving/transmission pipe 101 and 102, is designated as AP and BP respectively in real time.After detecting and having touch control operation in the first touch area 103, this method determines the position of touch point P according to following steps.
This method both can probably judge by the value comparing AP and BP that touch point P was positioned at top or the bottom of touch area 103, also can by calculating the accurate coordinates of touch point P accurately.
The first: the size of the value of AP and BP that can directly utilize transducer to obtain when environment for use is substantially upper portion or the bottom only needing to distinguish touch area directly obtains the position of P point; The second: when environment for use be need carry out the coordinate accurately calculating touch point P when, the computing formula that can be obtained by this method is directly calculated.The present invention just can control the ceiling light in the first corresponding touch area or the ceiling light in the second touch area owing to only needing to obtain touch point in the first touch area 103 or the second touch area 104.Therefore, the first is described in detail
The first: the specific embodiment by means of only Fig. 2 is described; First according to detect and obstacle distance AP and BP calculated judges, this touch point is positioned at the first touch area 103 above OX axle or the second touch area 104 be positioned at below OX axle; Shown in figure 2, in figure, PO ＇ is a boost line, and PO ＇ is vertically intersected on O ＇ point with AB; So according to Pythagorean theorem in right-angled triangle AO ＇ P and right-angled triangle BO ＇ P:
As quadrangle GHEF above touch point P is positioned at OX axle, due to O ＇ B>O ＇ A, so composite type (1) and formula (2) can obtain AP<BP;
When touch point P is positioned on OX axle, due to O ＇ B=O ＇ A, so composite type (1) and formula (2) can obtain AP=BP;
When touch point P is positioned at the quadrangle GHDC below OX axle, due to O ＇ B<O ＇ A, so composite type (1) and formula (2) can obtain AP>BP.
So this method is first-selected can according to detect and obstacle distance AP and BP calculated judges the fuzzy ranges of current touch point P; As AP<BP, then judge that P point is the quadrangle GHEF be positioned at above OX axle, indicates the regional extent 103 of finger touch bulb one printing opacity face shield; If the bulb in 103 one is closed condition, then after the regional extent 103 of bulb one printing opacity face shield is touched, then bulb one is lighted automatically; On the contrary, if bulb one illuminating state, then after the regional extent 103 of bulb one printing opacity face shield is touched, then bulb one automatic distinguishing; As AP<BP, then judge that P point is the quadrangle GHDC be positioned at below OX axle, indicates the regional extent 104 of finger touch bulb two printing opacity face shield; If the bulb in 104 two is closed conditions, then after the regional extent 104 of bulb two printing opacity face shield is touched, then bulb two is lighted automatically; On the contrary, if bulb two illuminating state, then after the regional extent 104 of bulb two printing opacity face shield is touched, then bulb two automatic distinguishing.
Wherein, with reference to figure 3, be described below in detail and determine that the detection method principle of position of touch is as follows:
This method is by the distance of wheel current control infrared receiving/transmission pipe 101 and 102 cycle detection barrier.When the regional extent 105 of finger touch bulb one printing opacity face shield, suppose that touch point is number in the figure P place, then namely this device can detect that the barrier at P place, touch point is respectively apart from the distance of infrared receiving/transmission pipe 101 and 102, is designated as OP and GP respectively in real time.
Because the distance OP of infrared receiving/transmission pipe 1 and infrared receiving/transmission pipe 2 102 is a fixing given value d3, so in triangle Δ OGP, three elongated all known, can calculate the concrete angle of ∠ GOP.Shown in figure 3, when touch location is positioned at P ＇, three length of sides of Δ OGP ＇ are identical with three length of sides of Δ OGP, and ∠ GOP=∠ GOP ＇.
So when touch point in the drawings P point time, the touch point detected by infrared receiving/transmission pipe 1 and infrared receiving/transmission pipe 2 102, also can be likely P ＇ point, but the touch area scope due to bulb is axisymmetric with OX axle, so be no matter the P ＇ point of P point or symmetry, all represent that position of touch is positioned at the regional extent 105 of bulb one printing opacity face shield.
In triangle Δ OGP, be following formula (3) according to the result that remaining profound theorem calculates ∠ GOP:
Shown in figure 3, can obviously infer, when the point of the finger touch of user is positioned at the regional extent 105 of bulb one printing opacity face shield, the distance OP of this touch point that infrared receiving/transmission pipe 1 records meets following formula (2), and the distance GP of this touch point that infrared receiving/transmission pipe 2 102 records meets following formula (3).

(d3－d2)≤GP≤(d3－d1)---------------------(5)
As the above analysis, during the ∠ GOP≤α calculated in formula that and if only if (3), and when two pairs of infrared receiving/transmission pipes meet the condition of formula (4) and formula (5) simultaneously, just indicate the regional extent 105 of finger touch bulb one printing opacity face shield; If bulb 1 is closed conditions, then after the regional extent 105 of bulb one printing opacity face shield is touched, then bulb 1 is lighted automatically; On the contrary, if bulb 1 is illuminating states, then after the regional extent 105 of bulb one printing opacity face shield is touched, then bulb 1 automatic distinguishing.
In like manner, when the point of the finger touch of user is positioned at the regional extent 106 of bulb two printing opacity face shield, the distance OP of this touch point that infrared receiving/transmission pipe 1 records meets following formula (6), and the distance GP of this touch point that infrared receiving/transmission pipe 2 102 records meets following formula (7).
(d3－d2)≤OP≤(d3－d1)-----------------------(6)
d1≤GP≤d2---------------------------------------(7)
As the above analysis, during the ∠ GOP≤α calculated in formula that and if only if (3), and when two pairs of infrared receiving/transmission pipes meet the condition of formula (6) and formula (7) simultaneously, just indicate the regional extent 106 of finger touch bulb two printing opacity face shield; If bulb 2 104 is in closed condition, then after the regional extent 106 of bulb two printing opacity face shield is touched, then bulb 2 104 can be lighted automatically; On the contrary, if bulb 2 104 is in illuminating state, then after the regional extent 106 of bulb two printing opacity face shield is touched, then bulb 2 104 can automatic distinguishing.
