Description
Technical Field
The invention relates to a method for ventilating an interior of a vehicle, in particular for automatically controlling a ventilation device of a vehicle. The invention further relates to a device and a server designed to carry out the method.
Background
The air mass in the interior space of the vehicle can be varied via the ventilation device of the vehicle. By closing the ventilation channel of the ventilation device, for example, external air with a lower mass can be prevented from being conveyed into the vehicle interior. The outside air with lower quality can be, for example, air with a higher proportion of harmful substances in the tunnel or in the surroundings of the industrial plant. Conversely, outside air with a higher quality can be conveyed into the interior of the vehicle by opening the ventilation duct of the ventilation device and additionally activating the blower. The outside air with the higher quality may be, for example, fresh air in a forest or mountain area.
In this connection, DE 102015211776 a1 discloses an olfactory (olfaktrisch) determined route selection. A driving route from a starting point to a destination is computed with the aid of selectable parameters and georeferenced olfactory-relevant data corresponding to the driving route. Here, the parameter includes at least one olfactory parameter.
The document US 2013/0080053 a1 relates to a dynamic route recommendation based on pollution data. Data describing a plurality of navigation routes between an origin and a destination is received. A plurality of contamination point values are determined that correspond to a respective one of the plurality of navigation routes. A cumulative point value is determined for each of the plurality of navigation routes. Data describing a plurality of navigation routes between the origin and the destination and a corresponding plurality of pollution point values and accumulated point values are communicated.
The document DE 102007050375 a1 relates to a method for using weather information in a vehicle not only in the context of navigation but also outside of navigation. Weather information may also be used in distance control, climate control, and/or safety systems for matching parameters to current or predicted weather and/or for prioritizing hazard warnings corresponding to current or predicted weather. If the vehicle has a navigation system, the weather information may be displayed in the base navigation graphic without prior route input and/or as Infotainment (Infotainment) in the vehicle. The weather information can likewise be used as a classification feature for traffic patterns in the time space, wherein the traffic patterns in the time space are selected taking into account the weather forecast contained in the weather information. The weather information can likewise be used to update the pre-calculated travel time or arrival time and/or to find a destination that matches the weather and/or destination information for the driver that matches the weather and/or advice for the driver for air conditioning of the vehicle that matches the weather.
Document DE 102014223774 a1 relates to an assistance device for a vehicle occupant in the case of an allergic reaction. A system for acquiring data of allergic reactions of a vehicle occupant includes an acquisition and/or storage device. By means of the collecting and/or storing device pollen in the area of the vehicle can be collected and/or stored. Using the data of the pollen (for example pollen type, pollen concentration, etc., which can be determined, for example, during driving or in the vehicle or later in a laboratory), a person-specific evaluation for the respective vehicle occupant can thus be achieved, which is based on a widely established data base. This can be achieved in particular using correspondingly relevant geographic data, time data, weather data and/or data of the pollen flight service (pollenfigurgenst). In this way, the medical diagnosis and treatment for the respective vehicle occupant can be intensively assisted and, if necessary, likewise improved. This makes it possible to drive in the case of an open sunroof (Schiebedach) or hood and to require the vehicle driver to close the sunroof or hood or to close these fully automatically in the case of the occurrence or danger of allergic reactions.
Disclosure of Invention
The aim of the invention is to improve the ventilation of the interior of a vehicle.
According to the invention, this object is achieved by a method for ventilating an interior of a vehicle, and a device and a server according to the independent claims. The dependent claims define embodiments of the invention.
The invention relates to a method for ventilating an interior of a vehicle. In the case of this method, a future position of the vehicle is determined, at which the vehicle is expected to arrive at a future moment. In addition, predicted air quality information is determined. The predicted air quality information indicates air quality information for a future location at a future time. In other words, air quality information for a future location at a future time is predicted. The ventilation device of the vehicle is actuated depending on the predicted air quality information. When, for example, outside air with poor quality is to be predicted for a future location, the interior of the vehicle can be filled with air with better quality by means of the ventilation device before reaching the future location and the ventilation device can be placed, for example, in the region with locations with poor air quality, in the circulating air (umloft), so that no or only a small air exchange with the poor outside air in this region is achieved. Conversely, when outside air with a better quality is predicted for a future location of the vehicle, the air exchange with the outside air may be delayed.
To determine a future position of the vehicle, a current position of the vehicle and a target position (Zielposition) for the vehicle may be obtained. The target position for the vehicle may be input, for example, by a vehicle user in a navigation system of the vehicle. The current position of the vehicle may be determined, for example, by a positioning system (positionbistestingunssys) of the navigation system. The driving route from the current position to the target position is determined, for example, by a navigation system. Depending on the driving route, a future position of the vehicle may be determined. Further, a future time at which the vehicle is expected to arrive at a future location may be determined. In this case, the usual cruising speeds and the current traffic state can be taken into account. For a determined future moment (e.g. in a time raster of several minutes (Zeitraster)), for example every 5 minutes, a corresponding future position is determined and for the corresponding future position a corresponding predicted air quality information is determined. With the aid of these predicted air quality information, the ventilation device of the vehicle can be controlled in such a way that the interior space of the vehicle is sufficiently supplied with outside air, wherein the interior space is supplied as much as possible with outside air of a better quality and as little as possible with outside air of a poorer quality.
To determine the predicted air quality information, for example, current air quality information may be determined that indicates air quality information for a future location at the current time. Depending on the current air quality information, predicted air quality information may be determined. For example, a typical daytime curve (tageszeitlicherVerlauf) of the air quality at a future location can be derived for a future time from the current air quality departure.
Alternatively or additionally, for determining the predicted air quality information, for example, current traffic density information may be determined, which indicates traffic density information for a future location at the current time. Depending on the current traffic density information, predicted air quality information may be determined. Traffic density at future locations may critically affect air quality. The higher the traffic density at a future location, the more harmful substances may be released there, which deteriorates the air quality. A reliable estimation of the air quality for a future moment in time can thus be performed on the basis of the traffic density at the future location.
Further, the determination of predicted air quality information may alternatively or additionally include the receipt of historical air quality information. The historical air quality information indicates air quality information for future locations at a past time. The predicted air quality information is determined depending on historical air quality information. For example, the historical air quality information may indicate a profile of air quality over the course of a day, particularly in the case of a determined weather situation and/or over the course of a day for a determined season and/or a determined weekday. The profile of the air quality over the course of a day can be used, for example, to estimate the air quality for a future time starting from the current air quality information. For example, historical air quality information may indicate that air quality is increasingly deteriorating during the morning and afternoon and improving again later during the evening and night. A reliable estimation of the air quality for a future moment in time can be performed based on this historical air quality information.
In the case of an exemplary embodiment, the ventilation device of the vehicle is actuated in such a way that the air flow (Luftmengstrom) is controlled through the passage of the ventilation system of the vehicle, for example, the passage of the lighting system can be actuated by means of a fan motor (L ü ftermotor) of the ventilation system, which has a valve that is opened or closed and furthermore delivers air through the passage of the ventilation system.
According to one embodiment, the predicted air quality information is determined at least in part in a server coupled to the vehicle. For example, the vehicle may communicate its future location and the accompanying future time to the server and the server may call the measurement data for air quality at the future location and determine the air quality at the future location for the future time, for example, taking into account predictive information (vorhersagelnformation) for traffic density and weather at the future location. The predicted air quality information so determined may be communicated by the server to the vehicle. Furthermore, the future position of the vehicle and the dependent future moment at which the vehicle is expected to arrive at the future position may be determined in the server depending on the current position of the vehicle and the target position for the vehicle. The server may, for example, comprise one or more servers in the internet, which collect information about air quality, weather conditions and traffic conditions and which can be coupled to the vehicle via a data communication connection, in particular a mobile wireless connection.
In the case of a further embodiment, the predicted air quality information is determined at least partially in a processing device of the vehicle. To this end, the processing device of the vehicle may, for example, retrieve, by one or more servers via, for example, a mobile wireless communication connection, information about the current air quality, the current or future traffic density, and the current or future weather for the future location of the vehicle and thereby determine predicted air quality information for the future location at the future time. Furthermore, historical air quality information stored in the processing device and recalled by the server may be considered in the context of determining predicted air quality information.
In the case of another embodiment, furthermore current local air quality information is determined. The current local air quality information indicates air quality information for the current location of the vehicle at the current time. The current local air quality information can be determined, for example, using sensors of the vehicle or be retrieved by a measuring station (measurement) located in the area of the current position of the vehicle, for example, via a mobile radio communication link. The operation of the ventilation device of the vehicle may be performed as follows. The interior space of the vehicle may be ventilated at a current time at a first ventilation rate and at a future time at a second ventilation rate. The first ventilation rate is set to be greater than the second ventilation rate when the current local air quality information indicates a better air quality than the predicted air quality information for the future time instant. Preferably, in this case, the blocking of the air exchange is set as the second ventilation rate, so that outside air is not conveyed into the interior of the vehicle. The first ventilation rate is set to be less than the second ventilation rate when the current local air quality information indicates a worse air quality than the predicted air quality information. Preferably, in this case, any air exchange between the outside air and the interior of the vehicle is prevented as the first ventilation rate. This prevents the air in the interior of the vehicle from being exposed to harmful substances or at least reduces the content of harmful substances in the air in the interior of the vehicle, and at the same time ensures a generally sufficient air exchange of the air in the interior of the vehicle.
The air quality information may include, for example, the concentration of carbon black particles, carbon monoxide, nitrogen oxides, and/or carbon dioxide in the air. Alternatively or additionally, further substance concentrations in the air may flow into the air quality information, such as dust concentrations, hydrocarbon concentrations or pollen concentrations.
According to a further embodiment, the predicted air quality information is stored in the case of the method, for example in a server or in a memory device in a processing device of the vehicle. When the vehicle arrives at a future location, local air quality information is acquired, for example with sensors of the vehicle or by means of a measuring station in the area of the future location. The stored predicted air quality information is compared with the acquired local air quality information and, depending on the comparison, a method for determining the predicted air quality information is adapted. A neural network may be used, for example, to facilitate determination of predicted air quality information based on current air quality measurements, weather values, and traffic density values, for example. The neural network may be trained by comparing predicted air quality information calculated by the neural network with actual air quality information.
Furthermore, local air quality information may be acquired and provided to another vehicle or a server in the case of the method, such that predicted air quality information for the other vehicle may be determined based on the local air quality information. The local air quality information indicates air quality information for the current location of the vehicle at the current time. The local air quality information may be determined, for example, by means of a sensor of the vehicle and provided to the server or to another vehicle via a mobile wireless communication connection.
According to the invention, a vehicle comprising a processing device is furthermore provided. In addition, the vehicle may include a wireless communication device to facilitate, for example, establishing a data communication connection with a server. The processing means are designed for determining a future position of the vehicle, which the vehicle is expected to arrive at a future moment in time. Furthermore, the processing device is designed to determine predicted air quality information.
The predicted air quality information indicates air quality information for a future location at a future time. Depending on the predicted air quality information, the processing device operates a ventilation device of the vehicle. In particular, the determination of the predicted air quality information may be performed in the processing device, for example, in the case of using additional information of the server. Alternatively, the determination of the predicted air quality information may be performed in a server. For this purpose, the processing device can transmit future positions and associated future times to the server, for example, via a data communication connection, and receive corresponding information from the server.
The device may in particular be designed for carrying out the method described previously or one of its embodiments and thus likewise comprise the advantages described previously in connection with the method. To this end, the device may comprise further components, in particular an interface to a sensor for determining the air quality and a user interface, for example a screen, a key or a touch-sensitive surface on the screen.
Furthermore, the invention relates to a server comprising a communication device and a processing device. The communication device is designed for transmitting data between the vehicle and the server, in particular for establishing a data communication connection between the vehicle and the server. The processing device is designed to determine a predicted air quality and to provide it to the vehicle for operating the ventilation device of the vehicle. The predicted air quality information indicates air quality information at a future time for a future location at which the vehicle is expected to arrive at the future time. The server may thus be designed in particular in connection with a vehicle for carrying out the method described previously or one of its embodiments and thus likewise comprise the advantages described previously in connection with the method.
Furthermore, the invention describes a computer program or software which can be loaded into a memory of a programmable control device or a computing unit or a processing device of a vehicle. All or different previously described embodiments of the method according to the invention can be implemented with the computer program when the computer program runs in a control device or a processing device of the vehicle. The computer program may require a program means (programemtel), such as a library and auxiliary functions, in order to implement the respective embodiment of the method. In other words, the computer program is used to protect software in which one of the above-described embodiments of the method according to the invention can be implemented or in which this embodiment is implemented. In this case, the software may be source code (e.g., C + +), which must also be compiled (translated) and concatenated or which must only be interpreted, or may be executable software code, which, for implementation, must only be loaded into the respective computing unit or control device (steuervorticichtung).
Within the scope of the invention, a vehicle is likewise provided, which comprises the device according to the invention.

Detailed Description
Fig. 1 schematically shows a vehicle 10 with a device 11, a ventilation device 13 and a sensor 14. Furthermore, fig. 1 schematically shows a server 20, for example a server which can exchange data with the device 11 via a wireless data communication connection 30.
The device 11 comprises processing means 12, for example electronic control means (such as for example a microprocessor). The device 11 can comprise further components which are not shown in fig. 1, such as, for example, interfaces for the ventilation device 13 and the sensor 14, a wireless interface for forming the data communication connection 30, as well as a user interface (for example a screen, in particular a touch-sensitive screen) and operating elements (for example push buttons). The device 11 may be part of a navigation system or an information system of the vehicle 10, for example. The ventilation device 13 may, for example, comprise a plurality of air ducts, via which air can be guided from outside the vehicle 10 into the interior of the vehicle 10. Furthermore, the ventilation device 13 may comprise a fan, in particular an electrically driven fan, and valves for opening and closing the plurality of channels. The processing device 12 is designed to operate the fans and valves via suitable control signals and thus to regulate the air supply to the interior of the vehicle 10. In particular, the processing device 12 may adjust the rate of ventilation for the interior space of the vehicle 10 in this manner. The sensors 14 may include one or more sensor elements that may measure a concentration of a substance in air in an ambient environment outside of the vehicle 10. The substance concentration relates, for example, to the concentration of carbon black particles, carbon monoxide, nitrogen oxides and/or carbon dioxide and thus to information about the air quality.
The concept air quality information is used within the scope of the invention and represents the quality of the air in the sense of breathing air for humans. The air quality information can indicate a better air quality when the concentration of harmful substances, such as, for example, carbon black particles, carbon monoxide, carbon dioxide and nitrogen oxides or, in addition, hydrocarbons or pollen, is small, preferably below legal limits. The air quality information indicates poor air quality when the concentration of one or more of these harmful substances increases, in particular above regulatory limits. Likewise, relative consideration of air quality information is possible. The lower the concentration of harmful substances in the air, the better the air quality. For example, the air quality information may comprise an air quality value which is determined in such a way that the concentration is combined with one another, for example, with a suitable weighting factor.
Furthermore, fig. 1 schematically shows a server 20 comprising a communication device 21 and a processing device 22. The server may be, for example, an internet server, which may establish a data communication connection 30 with the device 11 of the vehicle 10 via the communication device 21. The data communication connection 30 can be realized here, for example, via a mobile radio communication network.
The way in which the device 11 works is first roughly outlined below and then described in detail in connection with fig. 2 and 3.
Which driving route the vehicle 10 is expected to take is known from the input of the destination in the navigation device of the vehicle 10. The predicted air quality information may be calculated in a suitable method and algorithm, as described in detail below. The predicted air quality information may, for example, specify which state the air quality at a location reaches at a determined future time. The calculation of the air quality information may be implemented, for example, in the vehicle 10 or in the server 20 (so-called back-end). In the latter case, the calculated air quality information may be transmitted to the device 11 via the data communication connection 30. Based on this air quality information, the vehicle 10 may facilitate exchange with outside air at locations with better air quality, and reduce or even prevent exchange at locations with poorer air quality. Technically, this can be achieved, for example, by switching on the circulating air function (umluff function) of the ventilation device 13 or by opening or closing a window or roof opening of the vehicle 10. In the event that the vehicle arrives at the location for which the air quality information is predicted, the actual air quality information may be acquired using, for example, the vehicle's sensors 14 and compared to the predicted air quality information. Based on the comparison, the prediction of the air quality information may be improved. For example, a so-called predictive model may be improved or a neural network used to calculate predicted air quality information may be trained.
The advantage of the predicted air quality information is that it reacts preventively and protectively to the incoming position of the vehicle 10. If the control of the ventilation device 13 is only effected in the event of poor air quality being entered (for example as measured by the sensor 14 at the vehicle 10), it is already possible for outside air with poor quality to reach into the vehicle interior. Furthermore, based on the predicted air quality information, the vehicle interior can remain shielded from the outside air for a longer period of time, since more fresh air is already introduced into the vehicle interior in advance at the location with the better air quality.
In detail, the apparatus 11 may be implemented in conjunction with the server 20, for example, in steps 101-112 shown in fig. 3. The steps described in the box drawn in dashed lines may be optional and may therefore be eliminated or replaced by other comparable steps.
In step 101, the current position of the vehicle 10 is acquired. The acquisition of the current position of the vehicle 10 can be effected, for example, via a global positioning system, for example by means of a satellite-assisted system such as GPS (global positioning system) or Galileo (Galileo system). In step 102, a desired target position for the vehicle 10 is obtained. The target location may, for example, comprise a destination entered into a navigation system of the vehicle by a user of the vehicle. Based on the current location and the target location, a travel route for the vehicle 10 may be determined in step 103. The driving route may be determined, for example, by a navigation system of the vehicle based on map material. Alternatively, the current position and the target position may be transferred to the server 20 and the travel route calculated in the server 20. The driving route calculated by the server 20 may then be transferred to the device 11.
Fig. 2 shows the vehicle 10 at its current position P1. As the target position, for example, a position P5 is input. The travel route 50 along which the vehicle 10 is predicted to move is calculated based on the current position P1 and the target position P5. Based on information about the travel route 50, such as, for example, speed limits, traffic obstacles, and current traffic density, an estimated time of arrival may be determined for any point along the travel route 50. When the vehicle 10 is at the position P1, for example, at the time t1, a time t5 at which the vehicle 10 is expected to reach the target position P5, for example, may be calculated. Further, the predicted time t3 at which the vehicle 10 is predicted to reach the position P3 can be calculated for the position P3 along the travel route 50. For some locations along the travel route 50, information is available that enables the determination of predicted air quality information at those locations. In the example shown in fig. 2, corresponding information for position P3 may be present, for example. Thus, in step 104, the time t3 at which the vehicle 10 is expected to reach the future position P3 is calculated, particularly for the position P3.
For a future location P3, for example, current air quality information is determined in step 105, for example by means of a measurement point at location P3 providing air quality information, the air quality information provided by this measurement point may be retrieved, for example, by means of the device 11 via the server 20. additionally, in step 106, current traffic density information at a future location P3 may be determined, for example by means of a corresponding traffic counting device (Verkehrsz ä hlung) at location P3 or by means of movement data of vehicles present in the area of location P68. likewise, the device 11 may be retrieved, for example, by the server 20, these traffic density information.
In step 108, predicted air quality information is estimated for location P3 based on available information, such as, for example, current air quality information, current traffic density information, historical air quality information, and/or weather forecasts. In step 108, corresponding further predicted air quality information can be estimated for further positions. For example, corresponding predicted air quality information may be predicted for the target position P5 predicted to be reached at a future time t 5.
In step 109, the ventilation device 13 may be adjusted during travel of the vehicle 10 along the travel route 50 taking into account the predicted air quality information for the position P3.
In the case of the assumption that, for example, a relatively good air quality is present at the position P1 and a relatively poor air quality is to be expected for the position P3, the device 11 can actuate the ventilation device 13 in such a way that the interior of the vehicle 10 is supplied with fresh air from outside the vehicle 10 at the time t 1. For this purpose, for example, the valves of the ventilation device 13 can be opened, the blower of the ventilation device 13 can be switched on and, if appropriate, even the window or roof opening of the vehicle 10 can be opened. Since it is expected that the air quality at position P3 and in the immediate surroundings around position P3 (for example in the region from position P2 up to position P4) is poorer than along the path from position P1 up to position P2, device 11 can, for example, actuate ventilation device 13 in the event of reaching position P2 in such a way that the supply of air outside vehicle 10 into the interior of vehicle 10 is substantially prevented. This can be achieved, for example, in that the blower of the ventilation device 13 is switched off and the valve of the ventilation device 13 is closed. Additionally, the window or roof opening of the vehicle 10 may also be closed automatically or upon interrogation in the context of a vehicle occupant.
In the case of the arrival at the position P3, the air quality can be determined in step 110 with, for example, the sensor 14 and thus the current actual air quality information for the position P3. The air quality information determined for position P3 may be communicated to server 20, for example, in step 111. The server 20 may use this air quality information for another vehicle, which may use the air quality information to facilitate performing the previously described method and to predict predicted air quality information for location P3. Furthermore, the air quality information determined for position P3 may be used in step 112 to adapt a prediction method for predicting predicted air quality information. For example, the determined air quality information for position P3 may be compared to predicted air quality information that is predicted for position P3. The prediction method may be adapted based on the comparison. When the prediction method is based on a neural network, for example, the air quality information determined for the position P3 may be used as training information.
In the case of a relatively good air quality, for example at the position P5, the device 11 can activate the ventilation device 13 in such a way that, in the event of reaching the position P4, the interior of the vehicle 10 is again supplied with fresh air from outside the vehicle 10 in such a way that, for example, the valve of the ventilation device 13 is opened and the blower of the ventilation device 13 is switched on. On continued travel up to the target position P5, the interior of the vehicle 10 can therefore be supplied with fresh air from outside the vehicle 10.
