る。The operation of the vehicle air conditioner configured as above will be described. When the left / right independent control is not commanded (for example, when the left / right independent control switch 52 is off), the control circuit 35 sets the driver side set temperature set by the dial 51DR, the indoor temperature sensor 41, and the outside air temperature. Based on the detection outputs of the sensor 42, the solar radiation sensor 43DR, and 43AS, the driver-side and passenger-side air mix doors 16D
Both R and 16AS are controlled similarly. Therefore, the temperature of air blown into the passenger compartment is equal on the driver's seat side and the passenger's seat side.

The opening degree of the driver side air mix door 16DR is controlled based on the detection outputs of the sensor 41, the outside air temperature sensor 41, and the solar radiation sensors 43DR and 43AS, and the passenger side set temperature set by the dial 51AS and the indoor temperature sensor. 41, the opening degree of the passenger seat side air mix door 16AS is controlled based on the detection outputs of the outside air temperature sensor 41, the solar radiation sensor 43DR, and 43AS. Therefore, when the driver-seat-side set temperature and the passenger-seat-side set temperature are different, the blowing temperature into the vehicle compartment is different between the driver-seat side and the passenger-seat side.

る安定期には無視できない問題となる。When the temperature of air blown into the passenger compartment differs between the driver's seat side and the passenger's seat side, the actual passenger compartment temperature also differs between the passenger's seat side and the driver's seat side. When the sensor 41 is provided on the driver's seat side, a deviation occurs between the actual indoor temperature on the passenger seat side and the recognized value of the indoor temperature sensor 41. Therefore, if the recognition value of the sensor 41 is used as it is to control the blowout temperature on the passenger seat side, comfort may not be obtained on the passenger seat side. This is not a problem during the transitional period (cooling down immediately after the air conditioner is activated or warming up) aiming to bring the vehicle interior temperature closer to the set temperature quickly, but the vehicle interior temperature approaches the set temperature to some extent. , It becomes a problem that cannot be ignored during the stable period when trying to maintain that state.

を作り出すことができる。Therefore, in the present embodiment, when the stable period is reached by the left and right independent control, the output value of the room temperature sensor 41 is corrected based on the difference between the driver's seat side preset temperature and the passenger seat side preset temperature, and the passenger seat An estimated value of the side room temperature is obtained (the details will be described later). The difference between the actual indoor temperature on the driver's seat side and the indoor temperature on the passenger's seat side substantially depends on the set temperature difference, and the indoor temperature sensor 4 is corrected accordingly.
This is because the deviation between the recognition value of 1 and the room temperature on the passenger side changes. By controlling the opening of the passenger side air mix door using the estimated value obtained by this correction and adjusting the blowout temperature, the driver side and passenger side passengers will always be affected regardless of the installation position of the indoor temperature sensor. It is possible to create an air conditioning environment suitable for each taste.

In step S1 of FIG. 2, initialization is performed, and in step S2, detection outputs of the indoor temperature sensor 41, the outside air temperature sensor 42, and the solar radiation sensors 43DR and 43AS are input. In step S3, the outside air temperature Tamb which is the detection output of the outside air temperature sensor 42 is processed to a value corresponding to the actual outside air temperature by removing the influence from other heat sources. In steps S4 and S5, the detection output (air temperature downstream of the evaporator) of the solar radiation sensors 43DR and 43AS and the intake sensor (intake temperature sensor) 44 is delayed, and in step S6, the detection output of the indoor temperature sensor is detected.

In step S9, the target outlet temperature is calculated based on the various sensor processing values and the corrected values of the set temperature, and the air mix door opening is controlled so that the target outlet temperature can be obtained. When the left-right independent control is commanded as described above, the air mix door 16 is set based on the driver-side set temperature and the passenger-side set temperature.

Details of 6) will be described with reference to FIG. In this control, the output value of the indoor temperature sensor 41 is corrected to estimate the passenger's seat side indoor temperature at the time of left and right independent control, and the driver's seat side passenger room temperature and the passenger's seat side indoor temperature are delayed so that the air mix door is operated. The temperature of each room for control is calculated. In FIG. 3, TINC0 is an output value (recognized value) of the indoor temperature sensor 41, α is a set temperature correction value obtained as a function of the outside air temperature, β is a deviation correction value used for correction to obtain the passenger side indoor temperature, tinc is the time constant used for delay processing, T'INC
0DR and T'INC0AS are the driver side indoor temperature processing value and the passenger side indoor temperature processing value that should be finally obtained, TPTCDR
And TPTCAS are driver seat side preset temperatures and passenger seat side preset temperatures input by operating the dials 51DR and 51AS, respectively, and a, b, T1 to T8 are constants.

値βを「０」とする。In step S605, it is determined whether the left / right independent flag is on. The left-right independent flag is turned off when there is no left-right independent control command, and is turned on when the same command is issued. When the left and right independent flags are off, the process proceeds to step S607, and the deviation correction value β is set to "0" in order to make the passenger's seat side indoor temperature T'INC0AS the same as the driver's seat side indoor temperature T'INC0DR.

によりβを求める。この式によれば、βは設定温度ＴPT
CDR，ＴPTCASの差が大きいほど大きくなる。If the left-right independent flag is on, the process proceeds to step S606, and it is determined whether (25 + α) -TINC0 (t-1) is in the state C or the state D shown in the figure. This compares the deviation between the reference value of the set temperature and the indoor temperature recognition value with a predetermined value, and corresponds to the determination of whether the air-conditioning state is the transition period or the stable period. If the state is C, it is determined that it is a transitional period and the process proceeds to step S607, where the passenger side indoor temperature processing value T'INC0AS
To be the same as the driver's seat side indoor temperature processing value T′INC0DR, β is set to “0”. On the other hand, if the state is D, it is judged to be a stable period and the process proceeds to step S608, and β is calculated by β = (TPTCDR-TPTCAS) × T7 + T8 using the driver side and passenger side set temperatures TPTCDR and TPTCAS. According to this equation, β is the set temperature TPT
The larger the difference between CDR and TPTCAS, the larger.

ようにすれば、きめ細かい補正が行える。By the way, the deviation between the actual passenger's seat side room temperature and the sensor recognition value differs depending on the blower fan air volume, the blowout temperature, the blowout port, etc. in addition to the above-mentioned set temperature difference. Therefore, T7 and T8 in the above equations are taken into consideration each time, for example, by considering the blower fan applied voltage, the outlet temperature calculated from the air mix door opening, or the set outlet mode (vent mode or foot mode). If it is changed, fine correction can be performed.

The value recognized by the indoor temperature sensor 41 itself is reflected in INC0DR, and the value obtained by correcting the value recognized by the sensor 41 by β is reflected in T'INC0AS. The delay process is to prevent the blowout temperature and the blower fan air volume from changing frequently, and is not essential to the present invention.

Even if it does not have the function to control the two seating positions independently, the above-mentioned problem may occur depending on the mounting position of the indoor temperature sensor. Therefore, in this case as well, it is based on the set temperature, blower fan air volume, blowout temperature, blowout port, etc. The vehicle interior temperature at any seating position may be estimated by correcting the recognition value of the indoor temperature sensor, and the estimated value may be used for air conditioning control.
