Fig. 2 illustrates the block diagram according to the command input system 100 of first embodiment.As shown in Figure 2, command input system 100 is provided with infrared camera 10, input controller 20 and thermostat unit 90.Thereby command input system 100 is connected to outside onboard system 200 and receives information by vehicle-mounted LAN.Command input system 100 will send to onboard system 200 by the order that vehicle-mounted LAN receives.
Use infrared cameras 10 to take image according to the command input system 100 of first embodiment by the order of vehicle driver's indication, thereby based on captured thus image data extraction and judge this order.Fig. 3 illustrates the example of layout according to the infrared camera 10 of first embodiment (same second embodiment and the 3rd embodiment according to explanation after a while).The hand 7 that Fig. 3 illustrates the vehicle driver is held the front elevation of the sensing region 6 under the situation of bearing circle 1.As shown in Figure 3, will be assembled on the jociey stick (steering column) 2 according to the infrared camera 10 of first embodiment; This infrared camera 10 is taken the image that comprises with the specific sensing region 6 of lower area: i) hold the hand 7 of bearing circle 1 and the ii) inwall at the Qianmen 4 of face 6A (part of vehicle) as a setting; And this infrared camera 10 obtains to be included in hand 7 (sensed object) in the sensing region 6 and the infrared data of background surfaces 6A.The sensing region 6 of She Zhiing is that the example of described any object comprises the part of vehicle driver's health for any object of eliminating except hand 7 and background from shot image data as mentioned above.Like this, what can be taken is background surfaces 6A and hand 7 (sensed object), correctly extracts the state of the indicated hand of vehicle driver 7 etc. thus.Here, Fig. 3 illustrates the position of the structural constituent of the vehicle with right-hand lay dish 1, and the vehicle that has left hand bearing circle 1 on the contrary has the structural constituent with position opposite position shown in Figure 3.
As shown in Figure 2, input controller 20 is provided with extraction apparatus 21, determining device 22, actr 23 and treater 24; And based on the order of carrying out the vehicle driver by infrared camera 10 shot image data.
According to by infrared camera 10 shot image data, extraction apparatus 21 extracts at least one in the moving of the shape of hands 7 and hand 7.Although be not particularly limited, extracting method is extracted the distribution based on the temperature spot in the temperature band of human hand temperature T 7 (24 ℃ to 34 ℃, skin temperature), thereby extracts in the moving of the shape of hand 7 and hand 7 at least one from above distribution.
Determining device 22 is judged the content of order based in the moving of the shape of the hand 7 that is extracted by extraction apparatus 21 and hand 7 at least one.Although be not particularly limited, at least one in the moving of the shape of the hand 7 that determination methods is extracted thus based on unique point (finger tip etc.) identification and hand 7.This determination methods can be method for mode matching in addition.According to first embodiment, with i) in the moving of the shape of the hand 7 that extracted thus and hand 7 at least one and ii) allocate in advance in the moving of the shape of the hand 7 of order and hand 7 at least one and compare, judge at least one the order in the moving of the shape of the hand 7 that is extracted and hand 7.Determining device 22 acquisition from readable memory (RAM or ROM) makes i in advance) command context and ii) at least one information that is associated in the moving of the shape of hand 7 and hand 7.Above information specified in advance with the moving of the shape of hand 7 and hand 7 at least one particular command that is associated.More than being associated can be i) with the given shape (for example pointing 71 number) of the relevant hand 7 of order (for example Zhuan Zhi ON/OFF) etc.; Or ii) corresponding to the combination of the given shape (for example pointing 71 number) of the relevant hand 7 of order grade and particular command (for example volume rising/reduction after the selection) etc.
When the poor T7-T6A between hand temperature T 7 and the background surfaces temperature T 6A is less than or equal to the first specified temp T1 (wherein based on by infrared camera 10 shot image data sensing temperature difference T7-T6A), treater 24 stops (based on captured view data) extraction operation and extracts operation after the operation, then above Stop message is exported to the vehicle driver.(in other words poor T7-T6A between hand temperature T 7 and background surfaces temperature T 6A is less than or equal to the first specified temp T1, the temperature difference is not enough) time, treater 24 correctly extracts this order, judge the command determination difficulty, thereby temporarily stop (using captured view data) extraction operation and extract operation after the operation.In addition, treater 24 is given the vehicle driver with above-mentioned expiry notification, thereby prevents that the vehicle driver from carrying out any unnecessary order input that may be caused by possible wrong identification.
Based on infrared camera 10 shot image data, first temperature sensor, 30 sensing hand temperature T 7 (the first sensing temperature T1-S) send to controller 70 with hand temperature T 7 then.First temperature sensor 30 is assumed to be the piece of the temperature spot of human body skin temperature band in the captured view data (24 ℃～34 ℃) vehicle driver's hand temperature 7, thereby will with temperature (mean temperature, the central portion temp etc.) sensing on top the temperature (the first sensing temperature T1-S) of vehicle driver's hand 7.According to first embodiment, sensing region 6 is set makes and do not take the images of anyone body portion except vehicle driver's hand 7, thereby correctly extract the view data of captured (corresponding to hand 7) by simple determination methods.
Equally, based on by the captured view data of infrared camera 10, the background surfaces temperature T 6A (the second sensing temperature T2-S) of the background surfaces 6A in second temperature sensor, the 40 sensing sensing regions 6 sends to controller 70 with this background surfaces temperature T 6A then.Second temperature sensor 40 is assumed to be background surfaces 6A with the temperature spot except human body skin temperature band (24 ℃～34 ℃) in the captured view data, thereby will be background surfaces temperature T 6A with temperature (mean temperature etc.) sensing on top.According to first embodiment, the sensing region 6 feasible images of any part except background surfaces 6A and hand 7 of not taking are set.Like this, the data of eliminating the hand 7 that is extracted from captured view data can be extracted the view data of captured background surfaces 6A.
The temperature (the 3rd sensing temperature T3-S) that three-temperature sensor 45 senses vehicle are inside and outside, and above temperature sent to controller 70.Outside vehicle temperature T e, vehicle interior temperature Ti and the windows of vehicles glass temperature Tw at three-temperature sensor 45 senses vehicle chaufeur places are as the inside and outside temperature of vehicle (car body, window-glass W).According to first embodiment, as three-temperature sensor 45 are the outside vehicle temperature sensors 51 of outside vehicle temperature T e that are used for the vehicle periphery at senses vehicle chaufeur place.Regulate among hand temperature T 7 and the background surfaces temperature T 6A at least one according to the outside vehicle temperature T e that senses by outside vehicle temperature sensor 51, can be at the poor T7-T6A that generates under the situation that the vehicle driver is felt under the weather between hand temperature T 7 and the background surfaces temperature T 6A.The vehicle interior temperature sensor 52 of the vehicle interior temperature Ti of the vehicle at senses vehicle chaufeur place also can be used as three-temperature sensor 45.Regulate among hand temperature T 7 and the background surfaces temperature T 6A at least one according to the vehicle interior temperature Ti that senses by vehicle interior temperature sensor 52, can be at the poor T7-T6A that generates under the situation that the vehicle driver is felt under the weather between hand temperature T 7 and the background surfaces temperature T 6A.In addition, from the cost angle, preferably use outside vehicle temperature sensor or the vehicle interior temperature sensor that is installed in the air-conditioning on the vehicle.
The example of first heat regulator 81 comprises steering wheel heater, bearing circle cooling vessel and the air-conditioning that is used to adjust hand temperature T 7, and the example of second heat regulator 82 comprises the air-conditioning that is used to adjust background surfaces temperature T 6A.Along with the control that controller 70 carries out, 81 heating of first heat regulator or cooling hand 7, perhaps second heat regulator 82 heats or cooling background surfaces 6A, thereby increases the poor T7-T6A between hand temperature T 7 and the background surfaces temperature T 6A.
Adjust among hand temperature T 7 and the background surfaces temperature T 6A at least one according to the controller 70 of first embodiment by following two kinds of methods:
First method
The 10,000 method at first is described:
Poor T7-T6A between hand temperature T 7 that is sensed by first temperature sensor 30 and the background surfaces temperature T 6A that sensed by second temperature sensor 40 is less than or equal to the first specified temp T1, when simultaneously vehicle interior that senses at three-temperature sensor 45 and exterior temperature (the 3rd sensing temperature T3-S) are less than the second specified temp T2, controller 70 according to first embodiment passes through first heat regulator 81, and promptly steering wheel heater and air-conditioning (hot air) adversary 7 heats.
Be used for the temperature controlled first specified temp T1 and be not particularly limited, can be with reference to the first specified temp T1 being set by infrared camera 10 shot image data right area departure temperature T 7 and background surfaces temperature T 6A based on whether.According to first embodiment, the first specified temp T1 is made as 5 ℃, this value suitably can also be arranged to other value according to the precision of infrared camera 10.In addition, the second specified temp T2 is arranged to determine that the environment heat around the vehicle driver is still not hot, perhaps cold still not cold.Come suitably to determine the second specified temp T2 according to the sensed object of three-temperature sensor 45.For example, according to the outside vehicle temperature sensor 51 senses vehicle external temperature Te of the three-temperature sensor 45 of first embodiment, and the outside vehicle temperature T e and the second specified temp T2 that controller 70 will be sensed thus compare.Like this, preferably the second specified temp T2 is set as that the vehicle driver feels cold usually or the outside vehicle temperature T e of heat.Equally, when the vehicle interior temperature sensor 52 senses vehicle internal temperature Ti of three-temperature sensor 45, preferably feel cold usually or the vehicle interior temperature Ti of heat is provided with the second specified temp T2 based on the vehicle driver.Have only the outside vehicle temperature T e that senses when three-temperature sensor 45 or vehicle interior temperature Ti to be lower than the second specified temp T2 and when therefore the vehicle driver feels cold (perhaps not hot), according to the temperature regulator 60 of first embodiment just adversarys 7 heat.Like this, can prevent that adversary 7 heats when the vehicle driver feels hot, thereby at the poor T7-T6A that generates under the situation that the vehicle driver is felt under the weather between hand 7 and the background surfaces 6A.
Second method
Second method then is described:
Poor T7-T6A between hand temperature T 7 that is sensed by first temperature sensor 30 and the background surfaces temperature T 6A that sensed by second temperature sensor 40 is less than or equal to the first specified temp T1, when simultaneously the vehicle interior that senses of three-temperature sensor 45 and exterior temperature (the 3rd sensing temperature T3-S) were more than or equal to the 3rd specified temp T3, controller 70 cooled off background surfaces 6A by the air-conditioning (cold wind) as second heat regulator 82.Similar to first method, can be based on whether with reference to the first specified temp T1 that second method is set by infrared camera 10 shot image data right area departure temperature T 7 and background surfaces temperature T 6A.The 3rd specified temp T3 according to first embodiment is arranged to determine that the environment heat around the vehicle driver is still not hot, perhaps cold still not cold.Sensed object according to three-temperature sensor 45 is suitably determined the 3rd specified temp T3.For example, according to the outside vehicle temperature sensor 51 senses vehicle external temperature Te of the three-temperature sensor 45 of first embodiment, and outside vehicle temperature T e and the 3rd specified temp T3 that controller 70 will be sensed thus compare.Like this, preferably feel cold usually based on the vehicle driver or heat outside vehicle temperature T e the 3rd specified temp T3 is set.Equally, when the vehicle interior temperature sensor 52 senses vehicle internal temperature Ti of three-temperature sensor 45, preferably feel cold usually or the vehicle interior temperature Ti of heat is provided with the 3rd specified temp T3 based on the vehicle driver.Herein, second specified temp T2 in first method and the 3rd specified temp T3 in second method can be mutually the same.
When the outside vehicle temperature T e that senses by three-temperature sensor 45 or vehicle interior temperature Ti more than or equal to the 3rd specified temp T3, the vehicle driver feels heat or when not cold, according to the temperature regulator 60 cooling background surfaces 6A of first embodiment simultaneously.Like this, when the vehicle driver felt hot, cooling background surfaces 6A rather than heating hand 7 were like this at the specified difference T7-T6A that generates under the situation that the vehicle driver is felt under the weather between hand temperature T 7 and the background surfaces temperature T 6A.
Although be not particularly limited, preferred way is that thermostat unit 90 has precedence over the operation of input controller 20 and operates postheating hand 7 (sensed object) or cooling background surfaces 6A, thereby the poor T7-T6A between generation hand temperature T 7 and the background surfaces 6A.Make input controller 20 can correctly extract and judge order based on the poor T7-T6A that pressure between background surfaces temperature T 6A and hand temperature T 7 generates at operation input controller 20 under the heated situation of background surfaces 6A.
Fig. 4 illustrates the step of control according to the command input system 100 of first embodiment.
(S101) as shown in Figure 4, after beginning, infrared camera 10 is taken the image of the specific sensing region 6 that comprises the hand 7 of holding bearing circle 1, thereby obtains the camera data about temperature traverse.
(S102) based on by infrared camera 10 shot image data, first temperature sensor, 30 sensing hand temperature T 7.
(S103) based on by infrared camera 10 shot image data, second temperature sensor, 40 sensings are the background surfaces temperature T 6A at the Qianmen 4 of face 6A as a setting.
(S104) temperature difference calculator 72 (see figure 2)s of controller 70 are calculated the poor T7-T6A between (vehicle driver's) hand temperature T 7 and the background surfaces temperature T 6A, and judge whether the poor T7-T6A that is calculated thus is less than or equal to the first specified temp T1.
(S105) under the situation of poor T7-T6A greater than the first specified temp T1 of being calculated thus (S104 is for denying), treater 24 continues order input operations (extracting operation, decision operation and executable operations).
(S106) based on by infrared camera 10 shot image data, extraction apparatus 21 extracts at least one in the moving of the shape of hands 7 and hand 7.
(S107) determining device 22 judge in the moving of the shape of the hand 7 that extraction apparatus 21 is extracted thus and hand 7 at least one whether be predefined order.
When at S107 when being, operation entering step S108.
(S108) the onboard system controller 200A of 23 pairs of onboard systems 200 of actr output is by the order of determining device 22 judgements.Based on the order that is received thus, onboard system controller 200A controls onboard system 200.
When display command not, all flow processs finish, and return the beginning part then.
(S110) return S104, under the situation of the poor T7-T6A that is calculated greater than the first specified temp T1 (S104 is for being), treater 24 shut-down operations (extracting operation, decision operation and executable operations), thus stop to export to the vehicle driver more than inciting somebody to action.
(S111) then, the outside vehicle temperature sensor 51 measuring vehicle external temperature Te (the 3rd sensing temperature T3-S) of three-temperature sensor 45, the vehicle interior temperature sensor 52 measuring vehicle internal temperature Ti (the 3rd sensing temperature T3-S) of three-temperature sensor 45 simultaneously.
(S112) controller 70 judges that whether the 3rd sensing temperature T3-S (outside vehicle temperature T e or vehicle interior temperature Ti) that is sensed by three-temperature sensor 45 is less than specified temp (the second specified temp T2 or the 3rd specified temp T3).
(S113) outside vehicle temperature T e or vehicle interior temperature Ti more than or equal to the situation of specified temp (the second specified temp T2 or the 3rd specified temp T3) under (S112 is for being), in other words, when the vehicle driver felt hot or not cold, controller 70 made and blows out cold wind from air-conditioning (second heat regulator 82) to the background surfaces 6A at Qianmen 4.
(S114) simultaneously, at outside vehicle temperature T e or vehicle interior temperature Ti under the situation less than specified temp (the second specified temp T2 or the 3rd specified temp T3) (S112 for not), in other words, when the vehicle driver felt cold or be not hot, controller 70 was opened the steering wheel heater as first heat regulator 81.At first heat regulator 81 is under the situation of air-conditioning, blows out hot air from air-conditioning to hand 7.
With reference to vehicle interior and exterior temperature (the 3rd sensing temperature T3-S), according to command input system 100 pressure generation hand temperature T 7 (sensed object or the identifying objects) of first embodiment and the poor T7-T6A between the background surfaces temperature T 6A, and the vehicle driver is felt under the weather, thereby recognition command correctly such as the shape of the hand 7 by the vehicle driver.In compact car (nutshell), wait in the winter time under the colder state, the command input system 100 heating hands 7 according to first embodiment then cool off background surfaces 6A in the hot season.Therefore, can eliminate the influence that causes by season, air themperature, hand temperature T 7 etc., thereby generate the specified difference T7-T6A between hand temperature T 7 and the background surfaces temperature T 6A, and the vehicle driver is felt under the weather.
Second embodiment
According to the command input system 100 of second embodiment of the invention structurally with basic identical according to the command input system of first embodiment.Yet the difference of second embodiment and first embodiment is, used by the captured view data of infrared camera 10 by the method for three-temperature sensor 45 sensings the 3rd sensing temperature T3-S.Fig. 5 illustrates the block diagram according to second embodiment.As shown in Figure 5, command input system 100 according to second embodiment has window-glass temperature sensor 53, this window-glass temperature sensor 53 is based on the camera data sensing window glass temperature Tw that is obtained by infrared camera 10, as vehicle interior and exterior temperature.
According to second embodiment, infrared camera 10 is set to jociey stick 2, make that window-glass W is also included within the sensing region 6 except hand 7 and background surfaces 6A.From by the captured view data of infrared camera 10, window-glass temperature sensor 53 extracts the infrared data of a part of window-glass W of the specific region that occupies sensing region 6, thus the temperature of this part of sensing.Window-glass W is as outside vehicle and in-to-in border, so window-glass temperature T w may change along with outside vehicle temperature T e.Outside vehicle temperature T e is high more, and window-glass temperature T w is high more, and outside vehicle temperature T e is low more, and window-glass temperature T w is low more.According to second embodiment, window-glass temperature T w is considered as vehicle interior and exterior temperature (the 3rd sensing temperature T3-S), thereby adjusts among hand temperature T 7 and the background surfaces temperature T 6A at least one according to the window-glass temperature T w that is sensed thus (the 3rd sensing temperature T3-S).
Fig. 6 illustrates the step of control according to the command input system 100 of second embodiment.As shown in Figure 6, according to substantially the same among the controlled step of second embodiment and Fig. 4, and from the flow process of S101～S111, has difference according to the controlled step of first embodiment.Particularly, at S101 infrared camera 10 with captured image data transmission to three-temperature sensor 45.At S111, three-temperature sensor 45 is based on captured view data sensing window glass temperature Tw (the 3rd sensing temperature T3-S).
Like this, second embodiment can be by normally used hardware resource sensing the 3rd sensing temperature T3-S such as infrared cameras 10, in other words, do not need to be provided with any new temperature sensors such as outside vehicle temperature sensor 51 and vehicle interior temperature sensor 52, thereby reduced cost, produced the effect except that the effect of first embodiment.
