Description

The invention relates to a device for adjusting the air quantity of at least one air nozzle of a vehicle.

Devices for adjusting the airflow of at least one air nozzle for interior ventilation of a vehicle are generally known. From the DE 105 09 495 C1 A method for controlling the ventilation of a vehicle interior is known, in which the interior ventilation is switched between supply air operation and recirculation operation depending on sensor-detected conditions, whereby a respective recirculation operating phase can be limited depending on the prevailing recirculation operating conditions. For this purpose, a ventilation control unit is provided which is implemented in digital logic.

Electric air nozzles are increasingly complex in design and include a variety of electrical and/or electronic components for different functions and settings.

The object of the invention is to provide a device for adjusting the air volume of at least one air nozzle of a vehicle, in which the number of analog electrical lines is reduced and which is compact and variably constructed.

The problem is solved according to the invention by a device for adjusting the air quantity of at least one air nozzle of a vehicle with the features of claim 1.

Advantageous embodiments of the invention are the subject of the dependent claims.

The device according to the invention for adjusting the air volume of at least one air nozzle of a vehicle comprises the at least one air nozzle with at least one adjusting vane unit for adjusting the air volume, at least one first motor unit for adjusting at least one first, in particular a horizontal, adjusting vane unit and/or at least one second motor unit for adjusting at least one second, in particular a vertical, adjusting vane unit, and at least one vane sensor for detecting a vane position of at least one of the adjusting vane units. Furthermore, the device comprises at least one optical display unit for visualizing the amount of air delivered through the air nozzle and at least one microcontroller for controlling the motor units for adjusting an air volume and/or for visualizing the amount of air delivered through the air nozzle and/or the detected louver position, wherein the louver sensor, the motor unit(s) and the optical display unit are connected to the microcontroller via signal technology and/or electrically, and wherein the microcontroller is configured to control and/or regulate the amount of air delivered by the at least one air nozzle for controlling the ventilation of a vehicle interior by means of corresponding control of the motor unit(s) for the corresponding adjustment of the adjustable louver units.

The advantages achieved with the invention lie particularly in the fact that all electrical components of the air nozzle are electrically and/or signal-wise coupled to a microcontroller. The microcontroller can be modular and include corresponding interfaces for the respective functions. Such an integrated design of all electrical components with a microcontroller for at least one air nozzle allows for the implementation of new functions at that air nozzle and/or new nozzle concepts. Furthermore, the modular design of the microcontroller allows for the standardization of the electrical/electronic architecture (also called E/E architecture) for different air nozzles. In addition, the number of wiring harnesses required in the vehicle for an air nozzle is reduced, in particular from more than eight connection pins to a maximum of six or fewer than six, preferably to four connection pins. Such a uniform, electrically/electronically integrated device for all electrical components of an air nozzle is cost-effective, space-optimized, and particularly lightweight, thus saving weight and costs compared to known air control units.

Additionally, the device can include at least one closing flap, at least one lifting magnet for opening or closing the closing flap, and at least one flap sensor for detecting a flap position of the at least one closing flap, in particular for determining a resulting set air volume.

Additionally or alternatively, the device may include at least one control wheel for manually adjusting the air volume and at least one incremental encoder for detecting a control wheel position, in particular for determining the set air volume, of the at least one control wheel.

Furthermore, the device includes at least the optical display unit for visualizing the amount of air conveyed through the air nozzle and at least one microcontroller for controlling the motor units and/or the lifting magnet for setting an air volume and/or for visualizing the amount of air conveyed through the air nozzle and/or the detected louver position. the detected position of the control wheel and/or the detected position of the flap, wherein the louver sensor, the incremental encoder, the lifting magnet, the flap sensor, the motor unit(s) and the optical display unit are connected to the microcontroller via signal technology and/or electrically, and wherein the microcontroller is configured to control and/or regulate the amount of air to be delivered to the at least one air nozzle for controlling ventilation of the vehicle interior by means of corresponding control of the motor unit(s) and/or the lifting magnet for the corresponding adjustment of the adjusting louver units and/or the closing flap.

In other words, the microcontroller is configured to primarily control and/or regulate the motor units based on the louver position detected by the louver sensor and the desired airflow. This ensures the desired airflow is delivered and, optionally, can be directed accordingly via the position of the adjustable louver units. Additionally, the microcontroller can be configured to take into account an airflow adjustable via the optional damper and/or an airflow adjustable via the optional manual control knob.

In particular, the microcontroller can additionally be configured to control and/or regulate at least one solenoid of the closing flap, depending on the flap position detected by the optional flap sensor and the control wheel position detected by the optional incremental encoder and/or the set louver position, in order to deliver the desired amount of air and optionally output it in a desired air direction via the position of the closing flap.

For example, the microcontroller can be configured to generate a magnetic control signal for the solenoid based on the transmitted flap position and to control the solenoid accordingly. By controlling the solenoid, the closing flap can be closed, opened, or moved to any intermediate position, thus adjusting the airflow.

Additionally or alternatively, the microcontroller can be configured to generate a motor control signal for at least one motor unit based on the transmitted louver position and to control the motor unit accordingly. By controlling the adjustable louver units, the motor unit can, in addition to adjusting the airflow via the closing flap, set or adjust the direction and/or shape of the airflow (also called air current) resulting from the position of the adjusted louver unit.

Additionally or alternatively, the microcontroller may be configured to take into account at least one vehicle comfort function, in particular a lowered or opened shading, an open or closed window, or the like, when controlling the lifting magnet and/or the motor unit.

Preferably, an integrated carrier unit can be provided on which the microcontroller, the at least one motor unit, the at least one lifting magnet, the vane sensor, the flap sensor, the incremental encoder, the optical display unit, and an interface for a single nozzle are arranged. Such an integrated carrier unit is particularly compact and lightweight. In particular, an integrated carrier unit can optionally be provided for different air nozzles from different vehicles or different model series.

For example, the integrated carrier unit can be a printed circuit board on which the at least one motor unit, the at least one solenoid, the louver sensor, the flap sensor, the incremental encoder, and the optical display unit are electrically and/or signal-wise connected to the microcontroller via conductor tracks and pin assignments. In particular, the microcontroller and the interface are electrically and/or signal-wise connected to provide a number of output signals, input signals, and/or supply signals. For example, the microcontroller can modularly implement a conventional air control unit (also called DVC or Digital Vent Control) and a body controller, similar to a toggle switch, for example, by means of implemented corresponding logic modules and software modules and their interfaces, in particular supply interfaces and communication interfaces.

For example, the microcontroller, the at least one motor unit, the at least one solenoid, the louver sensor, the flap sensor, the incremental encoder, and the optical display unit can be electrically and/or signal-wise connected via the interface to a central control unit and/or to a bus system, in particular a CAN bus system or a LIN bus system. A single microcontroller can also be used to control the motor units and/or solenoids for adjusting the air volumes of multiple air nozzles and/or for visualizing the air volumes delivered by the air nozzles. The detected louver positions and the resulting airflow, the detected control wheel positions and/or the detected flap positions should be displayed on the corresponding optical displays.

Preferably, each air vent has its own dedicated microcontroller (also called a control unit). This single microcontroller serves as the basis for integrating all functions of all electrical and/or electronic components of the air vent. Alternatively, a single central microcontroller (also called a central control unit) can be used for multiple air vents. The central microcontroller can be configured to monitor and control multiple air vents and, optionally, other vehicle functions, such as power windows, headlights, sunshades, or the like. By using such a central microcontroller, which monitors and/or controls the airflow and, optionally, other vehicle functions and/or comfort features, decentralized or separate individual control units or microcontrollers can be eliminated.

In summary, the device with a single microcontroller for each air nozzle enables a combination of reduced motor units for that single air nozzle, improved operation of the airflow adjustment for that single air nozzle, and improved control of the electrical and electronic elements/components of that single air nozzle. This allows for synergies in hardware design and structure for different air nozzles. Furthermore, smaller and therefore more cost-effective motors, especially those without their own microcontroller, can be used, reducing the number of connection pins from six to four. The position sensors, such as potentiometers, for detecting the position of the adjustable vane unit (also called the air guide element) are thus also connected to and read via the new single microcontroller. This eliminates the need for a separate electrical/electronic connection via the motor's terminals.

Corresponding parts are assigned the same reference symbols in all figures.

1 shows a schematic representation of a device 1 according to the invention for adjusting the air quantity of at least one air nozzle 2 of a vehicle.

Device 1 is part of air nozzle 2, which directs a quantity of air, circulated for example by an air conditioning system, into the vehicle interior. Air nozzle 2 can be located and mounted, for example, in an instrument panel, center console, armrest, B-pillar, or similar location within the vehicle.

The air nozzle 2 can comprise at least one adjustable louver unit 3. For example, the air nozzle 2 can comprise horizontally extending louvers as a first adjustable louver unit 3.1 and/or vertically extending louvers as a second adjustable louver unit 3.2. The adjustable louver units 3 are, for example, pivotally mounted.

Each of the adjustable louver units 3 can be equipped with a corresponding motor unit 4 (also called a servo motor or actuator). The first adjustable louver unit 3.1 is electrically operated by a first motor unit 4.1, and the second adjustable louver unit 3.2 is electrically operated by a second motor unit 4.2, in particular, they are electrically adjusted or moved. The shape and/or direction of the airflow exiting the air nozzle 2 into the vehicle interior can be adjusted or moved by means of the adjustable louver units 3. For this purpose, the louvers of the adjustable louver units 3 are automatically, in particular controllably, moved in their position by means of the motor units 4. A rotary movement of the respective motor unit 4 changes the position of the horizontal and/or vertical louvers.

The device 1 also includes at least one closing flap 5. The amount of air exiting from the air nozzle 2 into the vehicle interior can be adjusted or changed by means of the closing flap 5.

To manually adjust the amount of air exiting air nozzle 2, at least An adjusting wheel 6 is provided. The adjusting wheel 6 can, for example, be designed as a continuous, stopless adjusting wheel or as a 360° adjusting wheel.

For the electrical adjustment of the air volume exiting the air nozzle 2, at least one solenoid 7 can be provided for opening or closing the closing flap 5. The solenoid 7 is, for example, an electromagnetic actuator (also called an electromagnet for short) which, when energized, performs a linear movement for the electrical adjustment or control of the closing flap 5.

Furthermore, the device 1 comprises at least one flap sensor 8 for detecting the flap position of the at least one closing flap 5 and/or at least one incremental encoder 9 for detecting the position of the control knob 6, in particular for detecting the set air volume. The incremental encoder 9 is specifically coupled to the control knob 6, by means of which a vehicle occupant can set or adjust the position of the closing flap 5. The incremental encoder 9 is specifically a sensor for detecting changes in angle. For example, in a calibration process, the number of clicks for one complete rotation of the control knob 6 (= 360° rotation) is detected by the incremental encoder 9; based on the determined total number of clicks for the 360° rotation, any other angular position of the control knob 6 can then be determined and the corresponding set air volume derived.

Furthermore, the device 1 comprises at least one slat sensor 10 for detecting the slat position of at least one of the adjustable slat units 3. Preferably, one associated slat sensor 10 is provided for each adjustable slat unit 3. The slat sensor 10 is a position sensor that detects the position or change in position of the slats. The respective slat sensor 10 can, for example, be designed as a potentiometer.

Additionally, the device 1 includes at least one optical display unit 11 for visualizing the air volume delivered by the air nozzle 2, the detected louver position, the detected control knob position, a set or desired nozzle function and/or nozzle comfort function, and/or the detected flap position. The optical display unit 11 is, for example, at least one LED display (LED = light-emitting diode). Multiple LED displays may also be provided.

The device 1 further comprises a single microcontroller 12 for the single air nozzle 2. The microcontroller 12 is configured to control and/or regulate the motor units 4 and/or the lifting magnet 7 for adjusting an air volume. In particular, the microcontroller 12 is configured to determine the air volume delivered by the air nozzle 2 (= air volume flowing into the vehicle interior) based on at least one set or desired nozzle function or nozzle comfort function, the louver position detected by the louver sensor 10, the control wheel position detected by the incremental encoder 9, and/or the flap position detected by the flap sensor 8. Depending on an occupant request, for example, a change in the nozzle function, the nozzle comfort function, and/or a desired change in the air volume and/or a desired change in the airflow, the microcontroller 12 automatically adjusts or adjusts the motor unit(s) 4 and/or the adjusting louver units 3. Preferably, the microcontroller 12 is configured to control and/or regulate the amount of air to be conveyed by the at least one air nozzle 2 for controlling the ventilation of a vehicle interior by means of corresponding control of the motor unit(s) 4 and/or the lifting magnet 7 for the corresponding automatic, in particular continuous or stepwise, adjustment of the adjusting louver units 3 and/or the closing flap 5.

For this purpose, the lamella sensor 10, the incremental encoder 9, the lifting magnet 7, the flap sensor 8, the motor unit(s) 4 and the optical display unit 11 are connected to the microcontroller 12 via signal technology and/or electrically.

For example, the microcontroller 12 is configured to generate a magnetic control signal for the lifting magnet 7 based on the transmitted flap position and to control the lifting magnet 7 accordingly. The microcontroller 12 is also configured to generate a motor control signal for the respective motor unit 4 based on the transmitted slat position and to control the respective motor unit 4 accordingly.

A function signal for a vehicle comfort function, nozzle function, nozzle comfort function, or the like, which is entered or set via an instrument panel, can be supplied to the microcontroller 12 via an interface 13, for example via a bus system 14, such as a CAN bus system or a LIN bus system. The microcontroller 12 can also be configured to additionally take the supplied function signal into account when controlling the lifting solenoid 7 and/or the motor unit 4.

Preferably, an integrated carrier unit 15 is provided for the air nozzle 2, on which the microcontroller 12, the respective motor unit 4, the respective lifting magnet 7, the respective lamella sensor 10, the respective flap sensor 8, the respective incremental encoder 9 and optionally the optical display unit 11 and the interface 13 for a single air nozzle 2 are arranged.

The integrated carrier unit 15 can be a printed circuit board on which the respective motor unit 4, the respective lifting magnet 7, the respective lamella sensor 10, the respective flap sensor 8, the respective incremental encoder 9 and the optical display unit 11 as well as the interface 13 with the microcontroller 12 are electrically and/or signal-wise connected by means of conductor tracks 16 and pin assignment.

Furthermore, the microcontroller 12 and the interface 13 can be electrically and/or signal-wise connected to each other to provide a number of output signals, input signals and/or supply signals. The microcontroller 12, the respective motor unit 4, the respective lifting magnet 7, the respective lamella sensor 10, the respective flap sensor 8, the respective incremental encoder 9 and the optical display unit 11 can also be electrically and/or signal-wise connected via the interface 13 to a central control unit and/or via the microcontroller 12 or directly to the bus system 14.

The device 1 can be configured as a single nozzle control for several air nozzles 2, for example a side nozzle, a center nozzle, or the like. Alternatively, a corresponding device 1, 1.1 to 1.3 can be provided for each air nozzle 2.

2 Figure 1 shows an embodiment for a single air nozzle 2, an electrical/electronic architecture of the device 1 on the integrated carrier unit 15 and in particular the electrical connections of the components on the carrier unit 15 by means of the lines 16, in particular by means of conductor tracks, and/or connection pins 17.

Module zones M1 to M4 for the various components of the device 1 are provided on the carrier unit 15.

A first module zone M1 serves to arrange and electrically connect the motor units 4, 4.1, 4.2 and the associated lamella sensors 10 of the adjustable lamella units 3, 3.1, 3.2 with the microcontroller 12 and/or the interface 13. For example, four or six supply lines for electrical connection to the microcontroller 12, in particular to four or six of its pins, can be provided for the respective motor unit 4.

The air nozzle 2 is electrically and/or signal-wise connected to a central control unit (not shown) via interface 13, for example a junction box in the instrument panel, and in particular via the bus system 14 (for example with two LIN pins), for example a LIN bus. Interface 13 can be designed, for example, as a connector strip or a terminal block. The electrical components on the carrier unit 15, such as the microcontroller 12, the motor units 4, the louver sensor(s) 10, the lifting magnet(s) 7, the flap sensor(s) 8, the optical display unit 11, and the incremental encoder(s) 9, are supplied via interface 13 using a connected supply pin 18 (for example with two pins +12V, -12V).

A second module zone M2 serves to arrange and electrically connect the respective lifting magnet 7 and the respective flap sensor 8 of the closing flap 5 with the microcontroller 12 and/or the interface 13. For example, two supply lines can be provided for the respective lifting magnet 7 for electrical connection with the microcontroller 12, in particular with two of its pins.

A third module zone M3 serves to arrange and electrically connect the optical display unit 11 and the incremental encoder 9 to the microcontroller 12 and/or the interface 13. For example, the incremental encoder 9, used to adjust the volume of air to be conveyed, has two or four connection tracks for electrical connection to the microcontroller 12, in particular to two or four of its pins, respectively. Similarly, the optical display unit 11, in particular an LED display, has two supply tracks for electrical connection to the microcontroller 12, in particular to two of its pins.

The microcontroller 2 can be arranged centrally or in the middle of the integrated carrier unit 15. Due to the implementation of all electrical components of a single air nozzle 2 on the integrated carrier unit 15 and its connection to the microcontroller 12, simple electrical wiring and, in particular, a compact electrical/electronic architecture are possible, with the interface 13 comprising a maximum of eight connection pins 17 or fewer, preferably only four or six connection pins 17. This significantly reduces the effort required for manual wiring. Furthermore, the nozzle functions and/or nozzle comfort functions implemented in the microcontroller 12 can be reprogrammed. 15 new functions will be implemented and/or existing functions will be updated or adapted in the existing carrier unit.

Interface 13, as a plug strip or terminal block, can include additional connection pins 17 for further electrical connections.

The central control unit 19 for the multiple air nozzles 2.1 to 2.3 is implemented on the integrated carrier unit 15, in particular a printed circuit board.

The central control unit 19 comprises devices 1.1 to 1.3 for each of the air nozzles 2.1 to 2.3, as previously described with reference to device 1.

Each device 1.1 to 1.3 is assigned to one of the air nozzles 2.1 to 2.3 and is constructed analogously to device 1.
