Description

TECHNICAL FIELD

[0001] The invention relates to a vehicle interior ventilation system according to the preamble of patent claim 1. It further relates to a vehicle, in particular a motor vehicle, which is equipped with such a vehicle interior ventilation system. BACKGROUND OF THE INVENTION

[0002] To ventilate the vehicle interior, fresh air is usually drawn in from outside through a filter using a fan and introduced into the vehicle interior through a system of air ducts and air vents located at various locations within the vehicle. Such a vehicle interior ventilation system typically includes an air filter and a fan as well as heat exchangers from a heating and air conditioning system. The air vents are usually provided by ventilation slots (for example, below the windshield), rigid louvered air vents (for example, for airflow to the front side windows), or movable air vents with manually or electrically adjustable louvers for spatially directing the outgoing airflow.

[0003] Such movable air vents are often located near the dashboard. The visible, movable louvers of such air vents make the direction of the escaping air flow easily visible to vehicle passengers.

[0004] New vehicle interior designs are increasingly using so-called joint vents, which have no visible slats for adjusting the flow direction of the outgoing air. With these joint vents, the direction of the outgoing air is defined by the section of the air duct located immediately in front of the air vent, the so-called outlet duct section. As a result, the direction of the air flow exiting these joint vents can no longer be visually determined. Particularly when several joint vents are located one below the other or next to each other, with their exiting air flows crossing each other, resulting air flows arise whose flow direction deviates from the outgoing air flow from the respective joint vent. The direction of these resulting air flows cannot be visually determined by a vehicle occupant.It is therefore difficult for the vehicle occupant to adjust the air flow as desired. STATE OF THE ART

[0005] US 2017 / 0253107 A1 discloses a vehicle interior ventilation system in which a dashboard is provided with several essentially horizontally extending and stacked air outlet slots, forming such gap vents. The flow directions of the air exiting these air outlet slots intersect outside the dashboard, thus forming a resulting airflow directed into the vehicle interior. The direction of this resulting airflow is determined by the flow velocity or volume flow of the airflow exiting the air outlet slots. The direction of the resulting airflow can be influenced by varying the respective flow velocity. PRESENTATION OF THE INVENTION

[0006] The object of the present invention is to provide a generic vehicle interior ventilation system which enables visual detection of the associated air flow in the vehicle interior even when using air outlet slots forming joint vents.

[0007] This problem is solved with the features of patent claim 1.

[0008] A vehicle interior ventilation system with at least one fan provided in an air duct housing, at least two air ducts fluidly connected to the air duct housing, and air outlets fluidly connected to the air ducts, wherein at least some of the air outlets form air outlet slots in a dashboard or other console of the vehicle, each of which forms the opening of an outlet duct section, and wherein at least one upper air outlet slot and at least one lower air outlet slot are provided in the dashboard or the console, from which the respective air flow exits in an air outlet direction predetermined by the respective outlet duct section, and wherein the air flows impinge on one another and form a resulting air flow with a resulting air flow direction, is characterized in thatthat an upper air sensor is provided for detecting the air flow velocity or the air volume flow in the upper air duct or outlet duct section leading to the upper air outlet slot, that a lower air sensor is provided for detecting the air flow velocity or the air volume flow in the lower air duct or outlet duct section leading to the lower air outlet slot, that the upper air sensor and the lower air sensor are connected to a control unit of a control device for signal transmission, that the control unit is connected to a display device provided in the dashboard or the console for signal transmission, and that the control unit is designed,to determine the resulting air flow direction of the resulting air flow from the recorded air flow velocities or air volume flows, taking into account the respective air outlet direction, and to form at least one control signal for applying the display device therefrom. ADVANTAGES

[0009] The vehicle interior ventilation system according to the invention enables a vehicle occupant to visually detect the air outflow direction or the flow direction of a resulting airflow even if air outlet slots, in particular so-called joint outlets, are provided instead of air outlets with visible, movable louvers. The display device visualizes the resulting flow direction of the resulting airflow and indicates this direction to the occupant.

[0010] Further preferred and advantageous design features of the vehicle interior ventilation system according to the invention are the subject of subclaims 2 to 10.

[0011] It is particularly advantageous if the display device is formed by light signal elements or at least has light signal elements.

[0012] It is further advantageous if the display device comprises a flat arrangement of light signal elements as a display panel, on which at least one active signal surface can be displayed. Such a flat display device is formed, for example, by a screen surface or a screen area of ​​a so-called smart bar extending across the width or part of the width of the dashboard.

[0013] It is also advantageous if the control unit is designed in such a way that a resulting air flow speed or a resulting air flow is determined from the size of the air flow speed or the air volume flow detected by the respective air sensor and that a surface area control signal is formed therefrom, which acts on the display device in such a way that the surface area of ​​the active signal area displayed on the display device is dependent on the determined size of the resulting air flow speed or the resulting air volume flow.Vehicle occupants intuitively associate such a variable surface area of ​​the active signal area with the intensity of the resulting airflow flowing into the vehicle interior, with a larger surface area of ​​the active signal area being equated with a higher air outlet velocity or a larger air volume flow of the resulting airflow. The size of the surface area of ​​the active signal area displayed on the flat display device thus correlates with the intensity of the resulting airflow (air velocity or air volume flow).

[0014] Further advantageous is an embodiment of the vehicle interior ventilation system in which the control unit is designed such that it controls the planar display device by means of an area control signal such that an upper area of ​​the display panel has the active signal area when the resulting flow direction is directed upwards, that a lower area of ​​the display panel has the active signal area when the resulting flow direction is directed downwards and that a central area of ​​the display panel has the active signal area when the resulting flow direction is directed substantially horizontally, i.e. towards the upper body of the vehicle occupant.

[0015] This design allows the vehicle occupant to easily determine whether the airflow is directed upwards, downwards, or directly toward their body. The upper, lower, and central areas of the display panel do not need to be discretely separated from each other; instead, the display provided by the active signal area can seamlessly transition between the respective areas.

[0016] In a further advantageous embodiment, which can be combined with other embodiments, the light signal elements are designed to display different colors depending on a color control signal. This refinement allows additional information to be transmitted to the occupant on the flat display device in addition to the previously described location- and area-related displays.

[0017] It is particularly advantageous if the control unit is designed such that a resulting air flow velocity or air volume flow is determined from the air flow velocity or air volume flow detected by the respective air sensor, and that the color control signal depends on the resulting air flow velocity or air volume flow. In this way, the intensity of the exiting air flow can be communicated by selecting a corresponding color for the active signal area.

[0018] Alternatively or additionally, at least one temperature sensor can be provided in the air duct housing and / or in the upper air duct or outlet duct section and / or in the lower air duct or outlet duct section, and the control unit can be configured to determine a resulting mixed temperature from the air temperature values ​​detected by the respective temperature sensor, taking into account the respective air flow velocity or the respective air volume flow, and the color control signal can be dependent on the determined mixed temperature. In this way, the temperature of the resulting air flow flowing into the vehicle interior is visualized to the occupant on the display device.In particular, when air of different temperatures is guided through the different air ducts, if a temperature sensor is provided in each air duct, the control unit can determine a mixed temperature resulting in the outgoing air, taking into account the air volumes flowing through the respective duct, and can display this on the display device either numerically and / or by means of a corresponding colour signal.

[0019] It is particularly advantageous if the display device is located in the dashboard or console between the upper air outlet slot and the lower air outlet slot associated with it. This allows the relevant information to be displayed to the vehicle occupant in close proximity to the respective air outlet slots, which is particularly advantageous when different air outlet slots or pairs of upper and lower air outlet slots are distributed across the width of the dashboard or console. In this case, each of these air outlet slots or pairs of upper and lower air outlet slots can be assigned its own display device.

[0020] A particularly advantageous development, which can be combined with any of the aforementioned embodiments, is characterized in that the control unit can apply a warning signal to the display device provided in the instrument panel, which triggers a priority warning display on the display device. This warning display can be generated completely independently of the vehicle interior ventilation parameters. Advantageously, this warning signal is a traffic-related warning signal, for example, a signal warning of a rear-end collision or the end of a traffic jam ahead.

[0021] Of course, it is also possible to provide other vehicle information as an input for controlling the display device. For example, a vehicle speed signal can be used to control the color display of the display device, so that the color displayed on the display device is an indicator of the current vehicle speed.

[0022] The invention is further directed to a vehicle, in particular a motor vehicle, equipped with at least one vehicle interior ventilation system designed according to the invention. This at least one vehicle interior ventilation system can be a ventilation system provided in a dashboard, but it can also be formed by a ventilation system formed in corresponding vehicle consoles in front of a second or further row of seats of the vehicle.

[0023] Preferred embodiments of the invention with additional design details and further advantages are described and explained in more detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

PRESENTATION OF PREFERRED EMBODIMENTS

[0025] Fig. 1 shows a vehicle interior ventilation system 1 according to the invention in a schematic representation as a vertical section through a dashboard 20 of a motor vehicle 2. The front windshield 22 of the motor vehicle 2 is shown in detail for better visualization and orientation with respect to the direction of travel F of the motor vehicle 2. An upper air vent 10 and a lower air vent 12 are shown in the dashboard 20, both of which are designed as air outlet slots 11, 13 in the dashboard 20.

[0026] The ventilation system 1 comprises an air duct housing 14, in which a heating, ventilation, and cooling unit 3 with a fan 30, a refrigeration system heat exchanger 32, and a heating system heat exchanger 34 located downstream of the fan in the air flow direction R are arranged in a known manner. At its inflow end, which leads to an air inlet (not shown), the air duct housing 14 is connected to a supply air duct 15. On the downstream side of the heating, ventilation, and cooling unit 3, the air duct housing 14 is connected to an upper air duct 16 and a lower air duct 18. Of course, additional air ducts can be connected here.

[0027] At its end opening into the vehicle interior 24, the upper air duct 16 forms the upper air outlet 10 designed as an upper air outlet slot 11, wherein the last section of the upper air duct 16 in front of the upper air outlet slot 11 forms an upper outlet duct section 17. At its end opening into the vehicle interior 24, the lower air duct 18 forms the lower air outlet 12 designed as a lower air outlet slot 13, wherein the last section of the lower air duct 18 in front of the lower air outlet slot 13 forms a lower outlet duct section 19. The respective outlet channel sections 17, 19 guide the air flowing in the respective air guide channel 16, 18 to the respective air outlet 10, 12 and align the outgoing air flow according to the course of the respective outlet channel section 17, 19, so that the outlet channel sections 17, 19 have the air outlet direction R oor R u determine.

[0028] The upper air outlet direction R o the air flow L exiting from the upper air outlet slot 11 o is directed slightly diagonally downwards (in the negative Z direction) according to the course of the upper outlet channel section 17. The lower air outlet direction R u the air flow L exiting from the lower air outlet slot 13 u is directed obliquely upwards (in the positive Z direction) according to the course of the lower outlet channel section 19. Consequently, the two air flows L o and L u at a distance from the instrument panel 20, mix and form a resulting air flow L r , which are in a resulting air flow direction R r into the vehicle interior 24.

[0029] An upper auxiliary fan 36 is provided in the upper air duct 16, with which the air flow in the upper air duct 16 can be accelerated toward the upper air outlet 10. Similarly, a lower auxiliary fan 38 is provided in the lower air duct 18, with which the air flow in the lower air duct 18 can be accelerated toward the lower air outlet 12. The fan 30, the upper auxiliary fan 36, and the lower auxiliary fan 38 can be individually controlled, allowing the flow speed in the upper air duct 16 and the lower air duct 18 to be set differently from one another.

[0030] Between the upper air vent 10 and the lower air vent 12, the instrument panel 20 is provided with a display device 4, which in the example shown is formed by a flat display panel 40. This flat display panel 40, which is designed, for example, as a matrix screen, has a plurality of light signal elements that illuminate the vehicle interior 24 when activated.

[0031] In the upper air duct 16 or in the upper outlet duct section 17, an upper air sensor 50 of a control device 5 is provided, which detects the air flow velocity or the air volume flow in the upper air duct 16. This upper air sensor 50 can be a stand-alone air flow sensor, as shown in Fig. 1, or it can be formed by a speed sensor of the upper auxiliary fan 36. Similarly, a lower air sensor 52 is provided in the lower air duct 18, which can also be designed as a standalone sensor for flow detection or as a speed sensor of the lower auxiliary fan 38. Both air sensors 50, 52 are connected to a control unit 54 of the control device 5.

[0032] In addition to the respective air sensor 50, 52, an upper temperature sensor 51 or a lower temperature sensor 53 can be provided in the air ducts 16, 18, which are arranged in Fig. 1 are also only shown schematically.

[0033] The Fig. 2A to 2C show different operating states of the vehicle interior ventilation system according to the invention. Fig. 2A shows a state in which the upper auxiliary fan 36 runs at a lower speed than the lower auxiliary fan 38, so that the flow velocity and thus the air volume flow in the lower air duct 18 is significantly higher than in the upper ventilation duct 16. The lower air flow L u therefore dominates when meeting the upper air flow L o the resulting air flow L r , which in the resulting air flow direction R r ' is directed diagonally upwards, i.e. towards the passenger's head, as indicated by the ventilation symbol on the right side of the Fig. 2A is shown symbolically.

[0034] In the Fig. 2B, the speeds of the upper auxiliary fan 36 and the lower auxiliary fan 38 are essentially the same, so that the flow velocities in the upper air duct 16 and the lower air duct 18 are also the same. The upper air flow L o and the lower air flow L u combine essentially equally to form the resulting air flow L r , which is directed essentially horizontally towards the vehicle occupant and thus guides the vehicle occupant in the resulting air flow direction R r ''' is supplied with air more or less evenly, as indicated by the ventilation symbol on the right side of the Fig. 2B is shown symbolically.

[0035] The Fig. 2C shows a state in which the speed of the upper auxiliary fan 36 is greater than the speed of the lower auxiliary fan 38, so that the flow velocity and thus the air volume flow in the upper air duct 16 is greater than in the lower air duct 18. The outgoing upper air flow L o therefore the outgoing lower air flow L dominates u , so that the resulting air flow L r in the resulting air flow direction R r '' is directed diagonally downwards, as indicated by the symbol on the right side of the Fig. 2C is shown symbolically.

[0036] In Fig. Figure 3 schematically illustrates the control of the display device 4. A signal proportional to the air flow velocity is transmitted wirelessly or via cable from the upper air sensor 50 and the lower air sensor 52 to the control unit 54 of the control device 5. Likewise, a temperature signal proportional to the air temperature in the respective air duct is transmitted wirelessly or via cable from the upper temperature sensor 51 and the lower temperature sensor 53 to the control unit 54. The control unit 54 also receives other vehicle operating signals from a Fig. 3, the vehicle electronics 56, which are only symbolically represented. These signals can include, for example, the current driving speed of the vehicle 1 or warning signals. Furthermore, the control unit 54 can receive a speed signal from a speed sensor 31 of the fan 30.

[0037] The control unit 54 processes the received signals by means of a control computer 55 provided in the control unit 54 and then sends control signals S to the display device 4. These control signals can be an area extension control signal S A , a range control signal S B , a color control signal S C and / or a warning signal S W or other suitable signals for controlling the display device 4. Different possibilities for controlling the display device 4 are described below using the Fig. 4 and Fig. 5 described.

[0038] Fig. 4 shows a front view of the instrument panel 20 from the perspective of a vehicle passenger in the direction of the arrow IV in Fig. 1. The instrument panel 20 is shown here only in part. The upper air vent 10, which forms an upper air outlet slot 11, and the lower air vent 12, which forms a lower air outlet slot 13, can be seen. The two air vents 10, 12 are arranged at a vertical distance from one another in the instrument panel 20 above and below a smart bar 21. The smart bar 21 has a transparent or translucent trim element 23 that extends essentially across the width of the instrument panel 20 (Y-direction). Various information devices are provided behind the trim element 23, which make visual information visible to the vehicle occupants through the transparent or translucent trim element 23. One such information device is the display device 4, which is arranged between the two air vents 10 and 12, as shown in Fig. 4 is shown by dashed lines. This display device 4 has a display panel 40 directed toward the vehicle occupant, which comprises a plurality of light signal elements (not shown) and is designed, for example, as an LCD or TFT screen.

[0039] The display board 40 can be virtually divided into three areas, an upper area 40', a lower area 40'' and a middle area 40''', as shown in Fig. 4 is illustrated by dash-dotted lines. This subdivision is not a physical subdivision of the display panel 40, but is merely implemented on the control side, as explained below.

[0040] Is the vehicle interior ventilation system located in the Fig. 2A, in which the resulting air flow L r in the resulting air flow direction R r' is directed diagonally upwards, i.e. towards the head of the occupant, the upper area 40' of the display panel 40 is illuminated. If the vehicle interior ventilation system 1 takes the Fig. 2B, in which the resulting air flow L r substantially horizontal in the resulting air flow direction R r ''' is directed towards the body of the occupant, the central area 40''' of the display panel 40 is illuminated. However, if the vehicle interior ventilation system 1 takes the Fig. 2C, in which the resulting air flow L r in the resulting air flow direction R r'' is directed diagonally downwards into the foot area and onto the legs of the occupant, the lower area 40'' of the display panel 40 is illuminated. In this way, the vehicle occupant can determine, based on the position of the illuminated area of ​​the display panel in the vertical direction, in which direction the resulting air flow is directed.

[0041] It is at the discretion of the expert not to provide high-contrast transitions between the illuminated area and the non-illuminated areas when controlling the three areas 40', 40'', 40''' of the display panel 40, but to design these transitions with a continuous brightness gradient and also to provide intermediate positions.

[0042] In Fig. 5 shows an alternative representation that can be combined with the other representations. Based on an area expansion control signal S received from the control unit 54 AThe surface area of ​​the illuminated display area on the display panel 40 can be changed. The oval illuminated display area 41, bordered by a solid line, can be enlarged or reduced in area, as shown by the dashed oval display area 41'. In this way, for example, the intensity of the resulting air flow L r , i.e. the air flow velocity or the size of the outgoing air volume flow, can be visually displayed. The smaller illuminated display area 41 represents a less intense resulting air flow L r , while the larger display area 41' in terms of the illuminated area ensures a more intensive resulting air flow L r Here, too, a gradual transition between different display areas can occur as a function of the air flow velocity or air volume flow.

[0043] This form of representation for visualizing the air flow intensity can be combined with the form of representation of the Fig. 4 combine so that the Fig. 5 shown oval display areas 41, 41' can move vertically across the display panel 40 and thus, in addition to the intensity of the air flow, also its direction (as in Fig. 4 shown).

[0044] Additional information can be transmitted to the vehicle occupant by selecting the color of the corresponding illuminated display, by controlling the color of the illuminated area displayed on the display panel 40 by a color control signal Sc received from the control unit 54 as a function of the determined temperature of the resulting outgoing air flow L rFor example, a color transition along the visible color spectrum from green to blue to red or any other color transition can represent a spectrum for the temperature level of the resulting outgoing air flow L r symbolize.

[0045] In this way, three different pieces of information can be transmitted to the vehicle occupant by means of the display panel 40 of the display device 4, namely information about the resulting air flow direction R r the resulting outgoing air flow L r , information about the intensity of the resulting air flow L r and information about the temperature of the resulting air flow L r .

[0046] As an additional benefit, the display panel 40, controlled by a warning signal S received from the control unit 54 W display priority warning information that temporarily replaces the Fig. 4 and Fig. 5 and the resulting air flow L r related displays into the background or hide them so that only the warning information is visible. If, for example, the motor vehicle 2 approaches the end of a traffic jam without a significant reduction in driving speed being detectable, a large-area warning signal from an emergency braking assistant can be displayed on the display panel 40 in order to draw the attention of the vehicle occupants, in particular the driver, to the impending dangerous situation. Of course, the display of other warning signals, for example when a specified maximum speed is exceeded, is also possible, without this being described in detail here.

[0047] The invention is not limited to the above embodiment, which merely serves to generally explain the core concept of the invention. Within the scope of protection, the device according to the invention may also take on embodiments other than those described above. In particular, the device may have features that represent a combination of the respective individual features of the claims.
