Embodiment 1

[0020] In this embodiment, an automobile is used as the vehicle, but the invention of the present application also includes other motorized two-wheeled vehicles driven by a driver, railway vehicles, airplanes, and the like.

[0021] A method of measuring the oxygen saturation in the blood of a passenger using transmitted light will be described using FIG. 1 .

[0022] A measuring unit 102 is incorporated in the steering wheel 101 . It is generally set at the position where the index finger is placed when the human hand 103 grasps the steering wheel. Since the size of the hand differs from person to person, it is also effective to provide a sliding mechanism or the like between the steering wheel 101 and the measuring unit 102 to have an adjustable position. The light emitting unit 104 and the light receiving unit 105 are assembled. The light-emitting unit may be composed of light-emitting elements such as LEDs, and the light-receiving unit may be composed of light-receiving ...

Abstract

The invention detects the state where a vehicle cabin is or the individual occupants are short of oxygen and eliminates this shortage of oxygen. Further, the invention prevents the occupant from developing high-altitude sickness when a vehicle runs in highlands. Still further, the invention constructs a system tough to the failure of sensors. There is provided an apparatus in which a system is constructed in such a way as to provide a vehicle with a function of measuring oxygen saturation in blood, a function of measuring oxygen concentration or carbon dioxide concentration, and a function of measuring altitude and can condition air in a vehicle cabin by use of a remaining function even in the event of a failure of the respective functions. With this, it is possible to eliminate a shortage of oxygen in individual occupants according to their states and hence to prevent the occupants from developing high-altitude sickness when the vehicle runs in highlands and hence to secure the safe running of the vehicle.

Description

technical field [0001] The invention relates to an air-conditioning device in compartments of automobiles, railways and the like. Background technique [0002] It is generally believed that the lack of oxygen in the compartment during vehicle transportation is one of the causes of reduced attention or drowsiness of the passengers. In addition, when driving on a high altitude, lack of oxygen can cause altitude sickness, especially if you move rapidly up and down, the risk is very high. Therefore, it is considered that the necessity of a technique for preventing altitude sickness is high. [0003] As a method for supplementing the lack of oxygen in the vehicle cabin, there is a technique described in Patent Document 1 that separates and removes nitrogen in the atmosphere to generate oxygen-enriched air. In addition, as described in Patent Document 2, there is also a vehicle driver's fatigue degree quantified by the number of suspension displacements, and when the number of t...
