In addition, the solar radiation sensor disclosed in Japanese Patent Application Laid-open No. 55-91413 is installed near each of the front, right side, rear, and left side window glasses in the vehicle interior, and has a photoelectric element that detects the amount of solar radiation. A solar radiation sensor that detects the sun's rays can readjust the temperature inside the room on the side that is irradiated with the sun's rays.

However, according to conventional vehicle air conditioners,
Temperature increases due to solar radiation are taken into consideration, but temperature detection points are limited to the top of the instrument panel and other locations, and temperature detection units cannot be installed on the sides of the vehicle due to space constraints. , it was not possible to detect the temperature rise due to sunlight entering from the entire surface of the vehicle.

Additionally, sensors installed inside the vehicle to detect the amount of solar radiation cannot be expected to reliably detect sunlight that enters from various directions and angles because the mounting position is restricted. If the air conditioner is loaded with cargo or other objects, the sensor itself may be blocked and the air conditioning system may not function properly.

In the above configuration, the solar radiation detector 7 provided on the roof of the vehicle 20 (the bonnet or trunk lid, etc.) has a shape that is a miniaturized version of the vehicle body, and the temperature detection elements 10, 11, 1 are arranged on the four sides of the solar radiation detector 7.
2 and 13, it is possible to reliably detect the influence of temperature rise due to solar radiation, regardless of the relationship between the vehicle 20 and the direction of solar radiation. For example, if the influence of solar radiation from the front of the vehicle is large,
In Figure A, the resistance value of the temperature detection element 10 decreases (due to negative resistance), and the potential at terminal a of the bridge circuit decreases compared to when the influence of solar radiation is small. Therefore, the potential difference between terminals a and b becomes greater than a predetermined level, comparator 25 outputs "1", and drive transistor 27 is turned on. This turns on the valve 19c of the actuator 19, which applies negative pressure in the intake manifold and lowers the actuator rod 19d. Due to this lowering, the opening degree of the air mix door 34 becomes smaller, thereby increasing the cooling of the front seat side and correcting the temperature increase due to solar radiation. On the other hand, if there is no influence of solar radiation in front of the vehicle, the temperature detection element 10 will not exhibit a decrease in the low resistance value, and the potential will not decrease at the terminal a of the bridge circuit. Therefore, the comparator 26 is turned on due to the potential difference between the terminals a and c, which is set to be higher than a predetermined level, and this turns on the drive transistor 28. Drive transistor 2
8 turns on valve 1 of actuator 19.
9b is turned on, and the actuator rod 19a is raised by the action of the negative pressure mentioned above. Due to this increase, the opening degree of the air mix door 34 increases, and as the resistance value of the resistor 24 increases in conjunction with this, when the potential difference between terminals a and c becomes smaller than a predetermined level, the actuator rod 19d opens. Movement stops. Similarly, in FIG. 4B, the opening degree of the air mix door 35 for the rear seats is controlled, and in FIG. The opening degree of 41 is controlled.
