An air conditioner installed in an automobile, such as a bus having many seats, controls the air conditioner body by inputting control conditions such as the temperature inside the vehicle, the amount of air blown from the air conditioner body, the air temperature and the outside air temperature. Equipped with means.

Recently, as the bus has become faster and more sophisticated, the specifications are such that the windows cannot be opened, so it is desired that the temperature inside the vehicle can be comfortably adjusted. However, as described above, the passengers feel that the air conditioning is uncomfortable because the passenger's sense of temperature deviates from the fact that the temperature distribution inside the vehicle, the air flow rate, the air temperature, and the outside air temperature are only input and centrally controlled. There are cases.

Therefore, recently, an air conditioner for a vehicle has been proposed in which passenger temperature sensation information felt by passengers at each seat is generated by a sensation notification switch or the like, and the air conditioner is controlled based on the passenger temperature sensation information. (Japanese Patent Laid-Open No. 55-5501
5 and JP-A-59-216717). This device
Since the air conditioner is controlled while referring to the temperature sensation from the passengers, the air conditioner is controlled based on the average passenger temperature sensation, but the temperature sensation inside the vehicle is not the same for all seats, but rather at the seat position. Therefore, if the overall temperature sensation distribution in the vehicle is known, it may be possible to artificially control the air conditioner from the driver's seat or the like.

[Problems to be Solved by the Invention]

The problem to be solved by the present invention is to know the temperature sensation distribution in the vehicle, and therefore when the temperature sensation distribution has a significant change in temperature sensation depending on the position, the vehicle interior temperature is artificially controlled. An object of the present invention is to provide an air conditioning system for an automobile capable of performing the above.

[Means for solving the problem]

In order to solve the above problems, the present invention provides an automatic control for controlling an air conditioner main body by inputting control conditions such as an air conditioner main body mounted on an automobile having a large number of seats and the vehicle interior temperature and outside air temperature. Means and passenger temperature sensation information generating means for generating passenger temperature sensation information felt by each passenger at each seat, and the automatic control means inputs passenger temperature sensation information from the passenger temperature sensation information generation means to obtain an air conditioner. In the air conditioning system for automobiles that controls the main body, the sensory temperature distribution monitor that displays the sensory temperature distribution based on the passenger temperature sensory information from the passenger temperature sensory information generation unit and the sensory temperature distribution monitor There is provided an automobile air conditioner characterized by further comprising artificial control means for artificially controlling the air conditioner main body under the displayed sensory temperature distribution.

[Action]

With this configuration, it is possible to automatically control the temperature inside the vehicle based on the temperature sensation information from the passengers on each seat. In the case where the temperature sensation is significantly different, the driver or an assistant can control the air conditioner main body artificially according to the temperature sensation distribution so as to eliminate the significant change in the temperature sensation.

〔Example〕

An embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows an automobile 14 having a large number of seats 12 such as a bus equipped with an air conditioner 10 (see FIG. 2) according to the present invention,
Air having a predetermined temperature and humidity is supplied from the air conditioner main body 24 shown in FIG. 2 to the warm air duct 18 provided on the floor 16 of the automobile 14.
Alternatively, it is led out into the vehicle from a cold air duct 22 provided on the ceiling 20.

The air conditioner 10 includes, as usual, an air conditioner main body 24 and an automatic control means 26 such as a CPU for controlling the air conditioner main body 24 by inputting control conditions such as the temperature inside the vehicle 14 and the outside air temperature. There is. The vehicle interior temperature is detected by the room temperature sensor 28, the outside air temperature is detected by the outside air temperature sensor 30, and the outputs of these sensors 28, 30 are input to the automatic control means 26. In addition, in addition to that, the blown air amount, blown air temperature, etc. are added as control conditions, but these are omitted in this specification. The automatic control means 26 calculates an appropriate air conditioning output from the control conditions input thereto, and controls the air conditioner main body 24 to generate this air conditioning output.

The air conditioner 10 of the present invention includes passenger temperature sensation information generating means 32 for generating temperature sensation information felt by passengers in each seat 12, and the automatic control means 26 is the passenger temperature sensation information generating means.
The air conditioner body 24 is controlled by inputting passenger temperature sense information from 32.

As shown in FIG. 3, the passenger temperature sensation information generating means 32 is provided at a predetermined position in front of each seat 12, for example, on the back side of the seat back of the seats in front of the second and subsequent seats, and in the front seat. It consists of three sensory notification switches 36 provided on the frame 34. These three sensation notification switches 36 include, for example, a thermal switch 36A that feels high at room temperature and heat, a comfortable switch 36B that feels that room temperature is moderate and comfortable, and a cold switch 36C that feels that room temperature is low and cold. There is. The automatic control means 26 inputs the information from these sensory notification switches 36 to obtain the sensory temperature distribution inside the vehicle, and the air conditioner main body 24 so that the sensory temperature becomes a uniform comfortable temperature as a whole.
Control.

As shown in FIG. 2, the air conditioner 10 of the present invention is installed on an instrument panel or the like of a driver's seat or the like, and based on passenger temperature sensation information from the passenger temperature sensation information generating means 32, distribution of sensory temperature inside the vehicle. For sensory temperature distribution display
