Definitions

  • Modern cars are usually processing device with a Lüf ⁇ and whether or not an air conditioner. With the help of this technical equipment, the climate and the air quality in the interior of the motor vehicle can be controlled manually or automatically.
  • To determine the quality of the air in the interior of the motor vehicle use today's air conditioning sensors. These sensors detect, for example, the air quality outside the motor vehicle, the position of the sun and the relative humidity in the interior of the motor vehicle.
  • the oxygen or the CO 2 content in the inhaled air is a main criterion for the well-being and the attention of the driver of the motor vehicle and the other persons in the interior of the motor vehicle.
  • Humans absorb oxygen from the inhaled air and, in return, release CO 2 into the environment.
  • the release of CO 2 within an "infinitely" large environment does not have any negative consequences for humans themselves, but if the CO 2 is released in a small enclosed space, such as that formed by the interior of a motor vehicle, the CO 2 concentration increases In this way, the oxygen available in the interior of the motor vehicle decreases, which can have a negative effect on the well-being and the attention of the driver and the other persons in the interior.
  • How quickly the oxygen concentration in the interior of a motor vehicle decreases or how fast the C0 2 concentration in the interior of the motor vehicle increases, is significantly influenced by the number of people who are in the interior of the motor vehicle. In addition, it affects whether the person consumes much or little air, such as for example, an adult or a child. If the CO 2 content in the air in the interior of the motor vehicle becomes too high, this causes fatigue in the passenger compartment. As a result, the attention for road traffic decreases at the same time and the accident risk increases. This process is also supported in modern motor vehicles in that the interior of the motor vehicle is sealed well against the environment, for example, to prevent the ingress of exhaust gases. Therefore, only the air conditioning system or the ventilation device of the motor vehicle provides the supply of the occupants of the motor vehicle with fresh air.
  • today's ventilation equipment or air conditioning systems do not include the oxygen or CO 2 content in the air of the vehicle interior in their regulation. It also be used any sensors that determine the composition of air in the passenger compartment of the vehicle and passed to an air conditioner further ⁇ .

It comprises the following steps: detecting at least one operating parameter of an air supply of the motor vehicle, in particular ⁇ sondere a ventilation device or an air conditioner, calculating a CO 2 - or 0 2 concentration in the interior space in response to the at least one operating parameter of the Air supply and supply of fresh air into the interior, if the C0 2 concentration exceeds a C0 2 threshold value or the ( ⁇ concentrations below an O 2 threshold.
  • the present invention provides a method for Klimarege ⁇ ment in the interior of a motor vehicle ready, the main ⁇ target in regulating the oxygen content in the air of the interior exists. In this way, road safety is supported, because the guaranteed supply of the driver with sufficient oxygen prevents fatigue for the driver and the occupants of the motor vehicle.

  • the thresholds advises for example a Radio Francege ⁇ the motor vehicle or can be preselected in a climate control or air conditioning system, the thresholds of geo ⁇ graphical features, preferences of the occupants of the motor vehicle, or be adapted to fit other constraints can.
  • a detection and consideration of a number of persons located in the interior and / or a respective weight of the number of persons located in the interior takes place in order to calculate the CO 2 or 0 2 concentration in the interior Interior of the vehicle Oberzu ⁇ lead with higher accuracy.
  • the present invention preferably calculates the CO 2 or O 2 concentration in the interior of the motor vehicle, the persons within the interior of the motor vehicle are included as relevant parameters in the calculation.
  • the consumption of oxygen in the interior is determined by the number of people breathing and their constitution. While adults consume more oxygen than children, for example, affects also the different weight of Rate Adults ⁇ Senen differently to the respective oxygen consumption. If these consumption-determining parameters are included in the calculation, the present O 2 or C0 2 concentration becomes more predictable with a higher accuracy. Direct the Wei ⁇ go into these calculations preferred operating Para ⁇ meter of air supply of the motor vehicle. While at ⁇ number of persons The consumption of oxygen, the operating parameters reflect the supply of fresh air or oxygen again.
  • a position of a recirculation damper and / or a position of a window and / or other ventilation devices are preferably detected and included in the calculation. It is also conceivable to detect the above-described position of circulating air damper, windows and other ventilation devices as a function of time. Since the supply of fresh air is sufficiently characterized using the known operating parameters, predictions can be made as to when, for a certain number of occupants, the CO 2 concentration will exceed a previously determined threshold. Because of this possibility of

  • the present invention therefore utilizes the knowledge that the conversion of oxygen into CO 2 is dependent on the number and constitution of the persons located in the interior of the motor vehicle. This knowledge is mathematically reconstructed, while in this calculation, the supply of oxygen and the number of persons in the interior are taken into account the conversion of oxygen into CO 2 via the operating parameters of the air supply. In this way, an oxygen balance for the interior of the motor vehicle is calculated, which provides the instantaneous oxygen content in the interior and / or predicts when a certain oxygen content in the interior is reached.

Abstract

La présente invention concerne un procédé de régulation de la composition de l'air dans l'habitacle d'un véhicule automobile. La régulation de la composition de l'air est basée tout d'abord sur la détermination de l'apport d'air frais à partir des paramètres de fonctionnement de l'apport d'air frais du véhicule automobile. La concentration en CO<SUB>2</SUB> dans l'habitacle du véhicule automobile est ensuite calculée sur la base du nombre des personnes présentes dans l'habitacle. Si le calcul indique le dépassement d'une valeur de seuil de CO<SUB>2</SUB>, de l'air frais est apporté de manière contrôlée dans l'habitacle du véhicule automobile.
