【Example】

Hereinafter, one embodiment of the present invention will be described based on the drawings. Figure 1 shows the self-contained structure according to this invention. A control block diagram of a vehicle air conditioner, FIG. 2 shows the operation flow of the device shown in FIG. 1. It is a chart.

[0008] The inside air sensor 10 is a sensor that detects the temperature of the air inside the vehicle. The sensor 11 is a sensor that detects the temperature of the air outside the vehicle interior. Correction sensor 12 converts the detection signals from the inside air sensor 10 and the outside air sensor 11 into the position of the vehicle. This is a sensor that is installed to indirectly compensate for the current conditions. Specifically, the solar radiation sensor that detects the amount of solar radiation on the vehicle, and the sensor immediately after passing the evaporator. A suction temperature sensor detects the air temperature, and also detects the engine coolant temperature. water temperature sensor etc.

[0009] The control panel 13 is provided in the vehicle interior, and allows the occupant to control the vehicle interior as desired. Various switches are provided to set the air conditioning status. Specifically, the sky Air conditioner switch that automatically controls the air conditioner, temperature that sets the air conditioner temperature inside the vehicle Set the control switch and temperature-controlled air outlet to achieve the desired air conditioning mode. Air outlet switch, REC switch to select the air intake position, and even a fan Switches such as a fan switch are installed to adjust the amount of air blown. this Among these switches, the temperature control switch functions as a temperature setting means. From here, a set temperature signal corresponding to the set temperature is output. Also, the air outlet The switch functions as a means to change the air conditioning mode, and from here you can change the mode information. The number is output. In addition, there is an outlet switch when the air conditioning condition is automatically controlled. or when the fan switch is operated, the air conditioning status is manually controlled from the time of the operation. It is now possible to move to control.

0010 The control device 20 usually includes the various sensors 10 to 12 described above and a control device. Each of the signals output from various switches etc. provided on the roll panel 13 Calculation to automatically control the air conditioning inside the vehicle to meet the passenger's requests based on signals. Do the following. Also, if the air outlet switch or fan is under automatic control, Once the switch operation is confirmed, the air conditioning status is manually controlled from that point on. control equipment When the air conditioner 20 shifts to manual control, passengers can freely set the air conditioning status. This can be done using various switches provided on the panel 13. That is, when automatic control is performed, the control device 20 uses various sensors. According to the calculation results based on signals from 10 to 12 and the control panel 13, The rotation speed of the fan motor 31 that blows temperature-controlled air into the vehicle interior, and the temperature of the temperature-controlled air Mix door actuator that adjusts the opening of the mix door (not shown) A mode door actuator that sets the rotational position of the motor 32 and the temperature-controlled air blowout position. The rotational positions of the tuators 33 are automatically adjusted. On the other hand, manual control In the case where the control device 20 is According to the operation of the switch, the rotation speed of the fan motor 31, that is, the temperature-controlled air is blown. quantity, the rotational position of the mix door actuator 32, that is, the temperature of the temperature controlled air, and the motor. The rotational position of the door actuator 33, that is, the air conditioning mode, can be changed to various settings. It is set arbitrarily without depending on the detection signals of the sensors 10 to 12. This manual control is the outlet When the operation is to be performed by operating a switch, the control device 20 is operated manually. Depending on the type of air conditioning mode that has been changed, the settings output from the temperature control switch A pseudo set temperature signal is calculated from the constant temperature signal, and manual control is performed based on the pseudo set temperature signal. control. In this case, the control device 20 functions as a temperature setting signal changing means. It turns out.

[0011] The automotive air conditioner of the present invention having the above configuration operates as follows. Ru. First, when the device starts operating, the control device 20 controls the inside air sensor 10 and the outside air sensor. Input the detection signals from the sensor 11 and correction sensor 12, and at the same time input the detection signals from the sensor 11 and correction sensor 12. Setting conditions for air conditioning conditions set by various switches on the control panel 13 Enter. Setting conditions specifically refer to the set temperature inside the vehicle using the temperature control switch. setting position for internal air circulation or outside air introduction using the REC switch (S1, S2). The control device 20 receives the detection signals and setting conditions input in the above steps. Based on the situation, the fan motor 31 is Optimal rotation speed, mix door actuator 32 and mode door actuator - Calculate the optimum rotational position of each of the 33 wheels and drive them based on the calculated values. Ru. This allows the desired amount of temperature-controlled air to be blown out from the desired outlet. As a result, the air conditioning condition as requested by the occupant is realized (S3). Below The above automatic control is based on detection signals from various sensors 10 to 12 that are input one by one. Then, until the manual control command is output from the control panel 13, In other words, it continues until the air outlet switch or fan switch is operated by a passenger. The process continues (S4).

0012 While this automatic control is being performed, the control device 20 inputs a manual control command. Is this manual control command due to the operation of the air outlet switch? It is determined whether this is due to the operation of another switch (S5). This judgment and the manual control command is due to operation using the air outlet switch. In other words, when the air conditioning mode is changed, the newly set air conditioning mode is When changing to cool mode, the occupants want to feel cooler. , the set temperature signal output from the temperature control switch is lowered by 2 degrees and pseudo-intensified. Set regulations. This setting is made by calculation in the control device 20. In other words, The control device 20 causes the temperature setting signal to be higher than the temperature setting signal output from the temperature control switch. A pseudo temperature setting signal that is 2 degrees lower is calculated, and the subsequent temperature control air during manual control is Temperature adjustment is performed based on this pseudo temperature setting signal. On the other hand, the newly set When the air conditioning mode is in heat mode, occupants desire an increased feeling of heating. Therefore, contrary to the above, the set temperature signal is artificially set 2 degrees higher. In addition, the bar When changing to level mode, such pseudo settings are not made and the temperature is The temperature setting signal output from the adjustment switch is set as is (S6 to S 8). The control device 20 uses the pseudo temperature setting signal calculated as necessary in this way. Based on this, set the mix door actuator 32 to a predetermined rotational position, and Temperature-controlled air is blown out from the selected outlet (S9). More than Manual control is a switch for outputting auto control commands to return to automatic control. For example, it continues until the air conditioner switch, etc. is operated. Then, check the detection signals of various sensors and the settings from the control panel 13 again. Automatic control based on conditions is performed (S10).

[0013] Since the automobile air conditioner according to the present invention is controlled as described above, for example, When the air conditioning mode under automatic control is in the bi-level state, the air outlet switch If vent mode is selected, the air conditioning mode is set to vent mode and From the vent outlet, instead of the set temperature signal from the temperature control switch, The air at the temperature controlled by the lower pseudo-set temperature signal is The message will be automatically displayed without changing the settings. Furthermore, for example, this manual system If the heat mode is set while the air conditioner is being controlled, the air conditioning mode is changed to heat mode and the temperature control switch is activated from the foot outlet. Controlled by a pseudo set temperature signal that is 2 degrees higher than the set temperature signal instead of the set temperature signal Temperature air can be blown out automatically without changing the setting of the temperature control switch. It becomes. Therefore, control is performed in accordance with the intention of the occupant.
