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 ⁇ .
- the above object solves a method for controlling an air composition in an interior of a motor vehicle. 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.
- a low-cost detection of the Heilzusammenset ⁇ provide the capacity, CO 2 - and / or 0 2 concentration calculated in the interior of the motor vehicle. This calculation is based, for example, on the operating parameters of a
- Ventilation system or an air conditioner that regulates the Frischluftzu ⁇ drive in the interior of the motor vehicle It is just ⁇ if conceivable to determine the air composition in the interior of the motor vehicle by means of sensors. The calculated or detected by means of sensors air composition forms the basis for the regulation of Frischluftzu ⁇ drove into the interior of the vehicle.
- the AIR SUPPLY ⁇ composition namely a falling below of an O 2 - threshold or exceeding a CO 2 -Schwellenwerts, the interior of the motor vehicle is supplied with fresh air.
- 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
- Calculation of predictions can therefore be supplied to targeted fresh air before reaching the CO 2 threshold, to prevent fatigue of the driver and the occupants of the motor vehicle.
- the number of people in the interior of the motor vehicle is detected by means of a Sen ⁇ sensor.
- a Sen ⁇ sensor can be different kind of work.
- such a sensor detects an open or a closed buckle, it measures the effective belt force or he determines the presence of a seat force.
- Seating force in this context refers to a weight that is applied by the seated person to the seat in the motor vehicle. In this way is detected by Hil ⁇ of each of these sensors fe the presence of a person. It is also conceivable, via the measurement of the above belt force or the above seat force, to estimate a weight of the respectively detected person.
- the interior of the motor vehicle is searched for persons with the aid of a camera system. Depending on the size of it ⁇ framed people, the weight of these individuals is subsequently assessed and further calculation basis.
- a further step of the preferred method is supplied with fresh air via the opening of an air recirculation flap, a window and / or sons ⁇ term ventilation devices of the motor vehicle, the interior space.
- Targeted opening occurs when the CO 2 threshold is exceeded or the O 2 -
- Threshold is fallen below. It is also conceivable to carry out a controlled opening in order to prevent an anticipated exceeding of the CO 2 threshold value in advance.
- the process of a motor vehicle initially an air supply of the motor vehicle is supported for controlling an air composition in a chamber to a detecting at least one Radiopa ⁇ rameters.
- the supply of fresh air to the interior of the motor vehicle is controlled Lich Get used for ⁇ by a venting means, an air conditioning system or a climate control.
- 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. Analogously, ei ⁇ ne CO 2 balance can be performed to determine when a particular CO 2 content is reached in the interior.
- the interior be ⁇ -sensitive number of people to determine the composition of air and taken into account.
- NEN the number of Perso ⁇ determines how much oxygen is converted by an average of the occupants of the motor vehicle via the natural breathing in CO 2. Since it is known that a different constitution of adults leads to a different degree of breathing and thus to a different degree of conversion of oxygen into CO 2 , the weight of the respective person in the interior of the motor vehicle is also preferably included in the calculation. The influence of the constitution of adults on the conversion of oxygen into CO 2 applies equally to children.
- the number of people in the interior of the motor vehicle by means of a sensor per possible seat in the Interior of the motor vehicle detected.
- a sensor detects, for example, whether a buckle closed or open ge ⁇ , that is, whether a person has buckled with this belt and buckle or not.
- Another version of a sensor is capable of determining the belt force acting on a belt during a braking operation. This belt force is generated indirectly by a person held with the belt he ⁇ . It is also conceivable to use sensors that detect the load on a seat in the interior of the motor vehicle, ie the seat force. Of course, such a seat force can only be determined if a person is actually in the respective seat.
- the interior of the motor vehicle is scanned with the aid of a camera system.
- an image evaluation carries out an estimation of the weight of the detected persons. This estimate is then forwarded to calculate the CO 2 or O 2 concentration in the interior of the motor vehicle.
- the weight of the person seated in this place is also derived from the belt force ascertained above. Similar information can be determined via the sensor, which determines the seat force mentioned above. Also, the determined via these sensors weight ⁇ forces of persons in the interior space of the motor vehicle are passed to the CO 2 - or O 2 - concentration to be calculated as accurately as possible. With the help of the sensors, therefore, the calculation of the CO 2 or O 2 concentration is based on the most accurate possible image of the persons located in the interior of the motor vehicle.
- a position is preferably a flap circulating air and / or detects a position of a window and / or Other pe ⁇ ger ventilation devices and are included in the calculation. If the positions of the recirculation damper, windows and other ventilation equipment are detected, it is also conceivable to include their position change over time in the above calculations. This additional information helps to improve the accuracy of the above method.
- the fresh air supply takes place via a filter system in the motor vehicle.
- This filter system also contributes to increasing the air quality, while its condition can be monitored by means of suitable sensors.
- the above method thus leads to an increase in road safety, since the concentration of the driver is ensured by a guaranteed sufficient oxygen supply.
- the control quality of the described method is improved by the inclusion of the number and weight of persons in the interior of the motor vehicle. Another advantage is that no gas sensors for analyzing the air composition in the interior of the motor vehicle must be installed. Furthermore, existing sensors, such as the belt force and seat force sensors, can be used to accurately calculate the oxygen concentration in the interior of the vehicle
- the ventilation device or air conditioning ⁇ system of the motor vehicle works mainly in recirculation mode. Since ⁇ be forth does not have to constantly cooled or heated from the outside air flowing in, which leads to a fuel saving and thus to a reduction of the exhaust emission.
