Especially under the situation of the position P1 in being contained in casing, can improve the accuracy of detection of back seat air conditioning area temperature.
Below, with reference to Fig. 5 and Fig. 6 its action is described.
Fig. 5 is the action flow chart of whole conditioning control unit 2, and Fig. 6 is the action flow chart of back seat air conditioning area.
The action incipient stage is according to the flow process of Fig. 5.
Among Fig. 5, at step ST1, the key one of engine starting is opened (ON), and vehicle is starting just.
At step ST2, conditioning control unit 2 judges that air-conditioning compressor 3 is any states in connection or the off-state.This judgement is that microcomputer 27 is judged according to the state of a control of compressor control portion 25.Be judged as under the situation of ' disconnection ' (step ST2-NO) at this, proceed to step ST3.
At step ST3, conditioning control unit 2 carries out the temperature of back seat air conditioning area and judges.
On the contrary, being lower than design temperature a1 at the temperature b1 of back seat air conditioning area (during a1＞b1), returns step ST2, continues to disconnect air-conditioning compressor 3.
In addition, step ST2 be judged as ' connection ' (step ST2-YES) time, proceed to step ST4.
At step ST4, conditioning control unit 2 compares the design temperature in the compartment.
That is, microcomputer 27 will compare from the design temperature (being made as ' A2 ') of the pre-set front stall air conditioning area of keyboard input part 22 and the design temperature (being made as ' B2 ') of back seat air conditioning area.
In the described comparison, be higher than the design temperature A2 of front stall air conditioning area (during A2＜B2) at the design temperature B2 of back seat air conditioning area, proceed to step ST5, the design temperature A2 that is lower than the front stall air conditioning area at the design temperature B2 of back seat air conditioning area (during A2＞B2), proceeds to step ST6.
At step ST5,2 pairs of back seat air conditioning areas of conditioning control unit carry out air-conditioning control.Utilize Fig. 6 that this control is described.
At step ST6,2 pairs of front stall air conditioning areas of conditioning control unit carry out air-conditioning control.
The diagram of circuit of following instruction diagram 6.
When the flow process of Fig. 5 proceeds to step ST5, carry out air-conditioning control according to the diagram of circuit of the back seat air conditioning area shown in this Fig. 6.
At step ST21, the microcomputer 27 of conditioning control unit 2 is confirmed the temperature (b1) of back seat air conditioning area.
In addition, when microcomputer 27 disconnects at air-conditioning compressor 3, make air-conditioning compressor 3 connect (starting) by compressor control portion 25.
At step ST22, the temperature b1 of 27 couples of design temperature a1 of the microcomputer of conditioning control unit 2 and back seat air conditioning area compares, and is higher than design temperature in the temperature of back seat air conditioning area and (during a1＜b1), proceeds to step ST23.
At step ST23, conditioning control unit 2 carries out air-conditioning control according to the temperature controller characteristic curve shown in Fig. 7.This Fig. 7 represents that the result of air-conditioning control makes to remain on design temperature a1 in order to eliminate back seat air conditioning area temperature b1 over time and the situation of temperature control (C1) is carried out in continuous action.
Specifically, microcomputer 27 utilizes continuous action to control air-conditioning compressor 3 and air-conditioning air door 4 by compressor control portion 25 and air door control part 26, and the control temperature makes the temperature of back seat air conditioning area remain on design temperature a1.
At step ST24, the microcomputer of conditioning control unit 2 27 judges that the temperature b1 of back seat air conditioning areas equals design temperature a1 not, when (step ST24-NO), continues step ST23 when unequal, when (step ST24-YES), proceeds to step ST25 when equal.
At step ST25, when the temperature b1 of back seat air conditioning area equals design temperature a1, the temperature control that microcomputer 27 end of conditioning control unit 2 utilize the continuous action of step ST23 to carry out, turning to design temperature a1 is the temperature control that utilizes intermitten of benchmark.
With above opposite, step ST22 relatively be less than or equal to design temperature for the temperature of back seat air conditioning area the time (during a1 〉=b1), proceed to step ST26.
At step ST26, it is the temperature control of benchmark that the microcomputer 27 of conditioning control unit 2 carries out with design temperature a1.
As mentioned above, according to this embodiment 1, because its structure is made the temperature b1 that utilizes the temperature sensor of installing in the back seat entertainment device 1 15 to detect the back seat air conditioning area, give conditioning control unit 2 with detected temperature data b1 through order wire 5, conditioning control unit 2 carries out air-conditioning control according to this detected temperatures b1 to the back seat air conditioning area, so do not need the temperature sensor of back seat air conditioning area special use, by like this, just can cost saving and can not increase installing space.In addition, the temperature sensor 15 of dress carries out the air-conditioning control of back seat air conditioning area in utilizing, and can suppress back seat entertainment device 1 self in-to-in temperature rise simultaneously, and is particularly when summer high temperature, especially effective to the air-conditioning control of the later back seat of the 2nd row.
In addition, because conditioning control unit 2 its structures are made when air-conditioning compressor 3 off-states, the temperature data b1 of design temperature a1 and back seat air conditioning area is compared, when the temperature data b1 of this back seat air conditioning area is higher than design temperature a1, make air-conditioning compressor 3 startings, make the temperature b1 of back seat air conditioning area smaller or equal to design temperature a1, so carry out forced cooling for the back seat air conditioning area during high temperature, especially the air-conditioning control (cooling) to back seat air conditioning area and back seat entertainment device 1 is effective especially when summer high temperature.
In addition, because conditioning control unit 2 its structures are made in the temperature control of back seat air conditioning area, when the temperature data b1 of back seat air conditioning area is higher than design temperature a1,, the temperature data b1 that makes the back seat air conditioning area carries out the control of continuous action for equaling design temperature a1, after the temperature data b1 of back seat air conditioning area and described design temperature a1 equate, control by intermitten in order to keep design temperature a1, so can make the temperature b1 of back seat air conditioning area promptly consistent with design temperature a1, simultaneously, after reaching design temperature, the control of restriction air-conditioning is to reduce the power consumption of this air-conditioning control, and its result can carry out all air-conditioning control efficiently.
Industrial practicality
As mentioned above, the air conditioning system for vehicle that the present invention relates to is suitable for and will installs in the automobile-used back seat display unit Temperature sensor be used for the air-conditioning control of back seat air conditioning area.
