Abstract

PURPOSE:To enhance the comfortableness of a vehicle, by computing a solar radiation quantity in each section in the vehicle passenger compartment in accordance with the outputs of a solar radiation detector and a vehicle advancing direction detector, the actual place of the vehicle and the time and date at present, so that the thermo-atmosphere in the vehicle passenger compartment may be controlled. CONSTITUTION:A signal indicating the advancing direction of a vehicle from an inertia navigation system 3, a signal indicating a relative position from a reference point, time and date data from a calender clock integrated circuit 4 and a signal indicating a solar radiation quantity of the horizontal surface from a photo-diode 5 are delivered to an arithmetic unit 6 to calcurate the solar radiation quantity in the passenger compartment of the vehicle. A resulted signal is delivered to a control device 7 that therefore changes the direction of blow-out of the air-conditioning device into the direction in which sunlight is directly irradiated to a human body, and adjusts an airflow. With this arrangement, uncomfortable feeling due to direct irradiation of sunlight may be prevented to enhance the comfortableness of the vehicle passenger compartment.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to air conditioning in vehicle interiors of automobiles, railway vehicles, and the like.

Configuration of conventional examples and their problems Conventional air conditioners of this type generally do not take special consideration with respect to solar radiation, or as shown in Figure 1,
A solar radiation sensor 2 is provided on the top surface of the instrument panel 1 to detect the full intensity of solar radiation, and the output of the solar radiation sensor 2 determines the set temperature of the air conditioner. I was correcting it. With this configuration, since the direction of solar radiation cannot be detected, there is always the problem that effective air conditioning cannot be performed to cope with direct solar radiation entering the vehicle interior.

OBJECTS OF THE INVENTION The present invention solves such conventional problems, and aims to completely eliminate the discomfort caused by solar radiation inside the vehicle interior by determining the amount of solar radiation reaching the valley of the vehicle.

Structure of the Invention To achieve this object, the present invention provides a solar radiation detection device that detects the entire amount of solar radiation, a direction detection device that detects the entire traveling direction of a vehicle, an output of the solar radiation detection device, and an output of the direction detection device. And a calculation device that calculates the total amount of solar radiation reaching each part of the vehicle based on the vehicle's current position and date and time, and a control device that controls the thermal environment inside the vehicle according to the output of the calculation device? It was established. With this configuration, it is possible to perform air conditioning according to the direction and amount of solar radiation on the vehicle.

Description of examples An embodiment of the present invention will be described below with reference to FIG.

In FIG. 2, the direction of travel of the vehicle and its relative position from the reference point are determined by the inertial navigation device 3 using a gyro sensor and a mileage sensor sound. The date and time data is obtained from the calendar clock C4 used for timekeeping, and the photodiode 5 is used as a solar radiation detection device to detect the total amount of solar radiation on the horizontal surface.

By calculating the data of the traveling direction of the vehicle, the current position, date and time, and the amount of solar radiation on the horizontal plane obtained from the above using the arithmetic unit 6 using a microcomputer, the entire position of solar radiation irradiating the inside of the vehicle interior is determined. When the human body is directly exposed to solar radiation, the air blowing direction of the air conditioner is completely changed in the direction of solar radiation using a side tilting device γ, and the air volume is adjusted according to the amount of solar radiation.

In the above configuration, if the interior of the vehicle is exposed to sunlight,
The shadow of sunlight on the human body? Since the airflow is applied in a counteracting manner, the discomfort caused by solar radiation to the human body can be completely eliminated.

Effects of the Invention As described above, the vehicle air conditioner of the present invention includes a solar radiation detection device that detects the total amount of solar radiation, and a solar radiation detection device that detects the entire amount of solar radiation, and the direction of travel of the vehicle. a direction detection device for detecting; a calculation device for calculating the total amount of solar radiation reaching each part of the vehicle from the output of the solar radiation detection device; the output of the direction detection device; the current position and date and time of the vehicle; and the output of the calculation device. Depending on the thermal environment inside the vehicle,
Since the structure is equipped with a JH control device, it is possible to detect the amount of solar radiation on which side of the vehicle with only one sensor for solar radiation, and based on that data, the temperature of the vehicle can be determined. Since it has a significant effect on the environment (goods), it has the effect of allowing detailed control to be performed depending on the direct solar radiation to the human body or the solar radiation to each part of the vehicle.
