According to the present invention, an air conditioner for a vehicle cancels the thermal interference with a rear-seat side from a front-seat side even when the difference in target temperature between the front-seat side and the rear-seat side is equal to a predetermined value or more. When the difference a set temperature on the front-seat side and a set temperature on the rear-seat side is equal to .+-.3 (.degree.C.) or more, a ratio of the outside air sucked into a front-seat air conditioner unit is decreased according to an increase in the difference between the set temperatures. In this way, since the amount of air which is blown out from the front-seat air conditioner unit and further flows into the rear-seat side is decreased, it is possible to cancel the thermal interference from the front-seat side, by means of air blown out from a rear-seat air conditioner unit.

In an air conditioner for automobiles, control unit for performing feedback control of blow off air is constructed in the form of an integral-added optimal regulator (M4) which performs the feedback control on the basis of optimal feedback gain predetermined according to dynamic model(s) of an air conditioning system including the vehicle compartment (M1) and the used air conditioning unit (M2). According to another feature of the present invention, an environmental condition, such as solar radiation to the vehicle compartment (M1), is detected to further accurately control the internal air temperature. In one embodiment, the internal variables including optimal feedback gain of the integral-added optimal regulator (M4) are changed in accordance with the variation in the dynamic model depending on the detected environmental condition. In another embodiment, in addition to the above-mentioned feedback gain, feedforward gain is used so as to finally determine controlled variables of blow off air control unit (M2). Furthermore, according to another feature of the present invention, temperature control may be performed at a plurality of different positions within a vehicle compartment using a plurality of air conditioning units without suffering from interference between a plurality of airflows.

摘要:
A vehicle air conditioner controls the air-conditioning automatically based on a control characteristic. The control characteristic, such as a blower voltage calculation map, is selected from plural control characteristics, or obtained by a calculation based on the personal information of the passenger or the manual operation for the air conditioner by the passenger. The control characteristic is selected or calculated as the one which is supposed to be suitable for the passenger's preference. The control characteristic can be used as a basis, or a specific characteristic for learning the passenger's preference after the control characteristic is determined.

A controlled variable-calculating apparatus and method that can easily calculate a controlled variable from one or more input variables and that can appropriately learn control characteristics for the calculation of the controlled variable. The control characteristics are represented as a surface embedded in an (n+1)-dimensional space, and are used to control one controlled variable from n variables. The control characteristics are approximated by an assemblage of flat planes corresponding to subspaces obtained by dividing an n-dimensional input space. For example, a two-dimensional input space defined by the interior temperature and the amount of sunlight is divided into 15 subspaces. Flat planes 1-15 are made to correspond to the subspaces, respectively. If the interior temperature and the amount of sunlight are entered, a decision is made as to which subspace the environmental conditions belong. The airflow is then calculated using an equation for any one of the flat planes 1-15. If the airflow is needs to be modified, the equation for the flat plane corresponding to the corresponding subspace is updated.

In a control system of a vehicle air conditioner, when a temperature difference between a previous target air temperature at the previous manual operation and a present target air temperature at the present manual operation is smaller than a predetermined value, that is, when it is estimated that a passenger's desired air amount is not set by the previous manual operation, a blower voltage control characteristic for controlling an air amount of a blower is corrected so that a set value at the previous manual operation is not affected to the present learning. Accordingly, it can prevent air-conditioning feeling from being deteriorated due to mis-learning.

When target blowout temperature to the inside of a vehicle is over a predetermined temperature in, an air temperature control system according to the present invention controls a cooling-ability controller to control air temperature of air cooled by a heat exchanger for cooling so that airflow becomes a predetermined temperature, and reduces the amount of blowout air into the vehicle per unit time compared with the amount of the blowout air when the target blowout temperature is under the predetermined temperature. Accordingly, the cooling air temperature due to the heat exchanger for cooling is fixed at the predetermined temperature even when the target blowout temperature is over the predetermined temperature. Therefore, generation of malodors due to dust and mold in the heat exchanger for cooling is prevented.

A vehicle air conditioning apparatus in which the larger the air conditioning cooling load in a vehicle compartment, for example, the larger the solar radiation amount, the lower the set temperature or the larger the temperature deviation between set temperature and inner air temperature, the narrower the swing ranges of swing louvers of respective center and side FACE blow outlets are set. Regardless of the swing range of the swing louvers, swing cycles of the swing louvers are set constant, and the narrower the swing ranges of the swing louvers, the slower the swing speeds of the swing louvers are set. Therefore, annoying feeling is reduced, and comfortable feeling for passengers is significantly improved.

A learning device that affects only the input-output relationships that should be additionally learned. A learning NN unit 8 capable of executing additional learning is provided separately from a learned NN unit 4 which is a basic control unit. The learned NN unit 4 produces a basic output in response to an input signal from a signal input unit 14, the learning NN unit 8 produces a correction amount desired by an individual person, and a desired control is performed based on the total value. When the output is changed, a difference is calculated between the changed output value and the basic output value from a first output unit 15, and the learning NN unit 8 executes the additional learning based upon the difference and the input value at this moment in compliance with a back-propagation method.
