Description
2313481 Control device for an air conditioning system of a motor vehicle
The invention relates to a control device for an air conditioning system of a motor vehicle having at least one control element which is arranged in an interior area of the motor vehicle and is mounted for movement in one control plane for manually setting an operating function, and with a switching arrangement for activation of an automatic operating function of the air conditioning system.
Such a control device is known from DE 38 21 702 Al.
The known control device has a plurality of rotary switches or rolling switches for manually setting specific operating functions of the air conditioning system. In addition, the control device has a push-button switch for switching on and off an automatic operating function of the air conditioning system, in which function the air conditioning system is controlled in an automatic mode prescribed by the vehicle manufacturer. In addition to the rotary elements or rolling elements, a push-button key is provided for controlling the automatic mode. So that different users can call up again respectively individual favourable settings of the manual operating function, the control device additionally has a memory which can be activated by means of a memory key constructed as a stopping switch.
The present invention seeks to provide a control device for an air conditioning system which, with simple means, permits an individual setting capability of an operating function and an automatic mode with simultaneous storage of the manually set operating function.
According to the present invention there is provided a control device for an air conditioning system of a motor vehicle having at least one control element which is arranged in an interior area of the motor vehicle and is mounted for movement in one control plane for manually setting an operating function, and with a switching arrangement for activation of an automatic operating function of the air 2 conditioning system, wherein the control element is mounted so as to be additionally axially movable in a perpendicular f ashion with respect to the control plane, and the said switching arrangement is operatively connected to the axial movement capability of the control element.
By virtue of the axial movement of the control element, the automatic operating function of the air conditioning system can be activated or deactivated without the position of the control element being changed in relation to the manually set operating function which has occurred previously. The control device according to the invention is particularly advantageous with a control element which is designed as a rotary knob and is additionally axially movable along its axis of rotation in order to activate and deactivate the automatic mode.
In a refinement of the invention, one front side of the control element is flush, in its axially inner limit position, with an outer contour of the edge section, surrounding the control element, of the interior area, and the activation of the automatic operating position by the switching arrangement is assigned to this inner limit position. By virtue of this refinement according to the invention, access to the control element during the activation of the automatic operating function for manually setting an operating function is prevented, since the control element cannot be grasped manually owing to the position embedded in the edge section of the interior area. Control can be effected in this position merely by renewed axial pressing-in which deactivates the automatic operating function again and presses out the control element again as far as its outer limit position over the outer contour of the edge section of the interior area by means of a spring mechanism.
Preferred exemplary embodiments of the invention are described below and illustrated with reference to the drawings, in which:- Fig. 1 shows a first control element of the embodiment of a control device according to the invention for an 3 air conditioning system of a passenger car, Fig. 2 shows a f urther control element of a control device according to the invention for an air conditioning system of a passenger car, Fig. 3 shows a schematic view of a section through part of the control device at the level of the control element, the control element being located in its outer limit position, Fig. 4 shows a schematic view of the control element according to Fig. 3 in its inner limit position, and Fig. 5 shows a schematic view of a central control unit of the control device.
A passenger car is equipped with an air conditioning system which is known per se by means of which the climate of the interior of the passenger car can be conditioned. In this context, the air conditioning system can be provided merely with a heating function or else additionally with a cooling function, so that the inventive term of the air conditioning system comprises both heating systems and combined heating and cooling systems. In order to control the air conditioning system, a control device, which has a plurality of actuator elements and key elements which constitute the control elements of the control device, is arranged in a cockpit of the passenger car which constitutes an interior area in the terms of the invention. These control elements control the individual functional devices of the air conditioning system, such as air flaps, blower, cooling compressor and the like, by means of corresponding switching and control arrangements. The operating functions of the air conditioning system can either be set manually according to the individual requirements of a user by means of the control elements of the control device, or else transferred to an automatic mode by means of a switching arrangement in which the air conditioning system is controlled in a function setting prescribed by the vehicle manufacturer. In an inventive exemplary embodiment which is not illustrated, the control device is accommodated 4 in a rear area console which also constitutes an interior area in the terms of the invention.
According to the this embodiment, the activation and deactivation of the automatic operating function of the air conditioning system can be carried out by means of a control element 3, 3a which serves simultaneously for manually setting an operating function area. The control element 3, 3a thus has a double function. For the manual setting of an operating function area of the air conditioning system, the control element 3 is constructed as a rotary knob which is mounted so as to be rotatable about an axis of rotation 4. The control element 3 is integrated in the control panel 1 of the control device, which simultaneously constitutes the front of the cockpit. The control element 3 is surrounded by an annular panel 2 which constitutes an inventive edge section of the cockpit. The control element 3a according to Fig. 2 corresponds essentially to the arrangement of the control element 3 according to Fig. 1. The control element 3a is, however, provided for controlling a different operating function area of the air conditioning system. For this reason, the annular panel 2a which surrounds the control element 3a is provided with different symbols. However, the control element 3a is also constructed as a rotary knob for manually setting the corresponding operating function area of the air conditioning system. The control element 3 according to Fig. 1 is used to control a blower of the air conditioning system, and, on the other hand, the control element 3a according to Fig. 2 is used to activate air flaps of the air nozzles leading into the interior. In order to activate or deactivate the automatic mode either of the respective operating function area to which the respective control element, 3, 3a is assigned or of the overall operating function of the air conditioning system, the control element 3, 3a is mounted so as to be additionally axially movable along its axis of rotation 4. For this purpose, the control element 3, 3a is provided with a shaft 5 which is coaxial with respect to the axis of rotation 4 and whose lower front end forms, according to Fig. 3, a switching pin for activating a switching key 8. The switching key 8 is part of the switching arrangement for activating and deactivating the automatic mode. The activation and deactivation of the automatic mode is thus ef f ected by means of a corresponding axial movement in the direction of the double arrow A of the control element 3, 3a and of the switching pin which is integrally connected to the control element 3, 3a. The switching signals of the switching key 8 which are brought about by the switching pin, i.e. by means of the shaft 5 and by means of the control element 3, 3a are passed on as digital signals via appropriate conductor tracks on a printed circuit board 9 over the line Sd to a central control unit 10 [Fig. 5]. Here, the signals are evaluated and passed on to various control outputs Sdiv which activate the corresponding electric drive units of the various functional devices of the air conditioning system. The manual adjustments of the operating function areas by rotating the control element 3, 3a are passed on by means of a rotary potentiometer which is connected to the central control unit 10 with the aid of connecting lines 7 and corresponding conductor tracks on the printed circuit board 9. Analogue signals Sa are passed on from the rotary potentiometer 6 to the control unit which, in turn after an appropriate evaluation, activates the various control outputs Sdiv for the functional devices of the air conditioning system. The shaft 5 of the control element 3. 3a is, for this purpose. connected in rotation with the rotary potentiometer 6, but is simultaneously held so as to be axially movable in relation to the rotary potentiometer 6 without it undergoing axial displacement. Additionally allocated in a non- illustrated fashion in the control element 3, 3a is an axially acting spring arrangement which ensures, in conjunction with the various latching positions of the control element 3, 3a, in technical terms a so- called "pushpush" mechanism for the control element 3, 3a.
In its outer limit position, the control element 3, 3a projects [Fig. 3] outwardly over the outer contour of the annular panel 2, 2a so that in this position it can be grasped 6 manually and rotated. In this outer limit position, the automatic mode is deactivated. In order to activate the automatic mode of the air conditioning system, the control element 3, 3a is easily pressed inwards, as a result of which the inner limit position [Fig. 4] is reached by means of the "push-push" mechanism. In this inner limit position, the automatic mode is activated. In this limit position, the front of the control element 3, 3a ends flush with the outer contour of the annular panel 2, 2a [Fig. 3], so that the control element 3, 3a cannot be grasped manually in order to rotate the control element 3, 3a. A renewed pressing- in of the control element 3, 3a causes the control element 3, 3a to snap back into its outer limit position according to Fig. 3. At the same time, the automatic mode is deactivated again. since the control element 3, 3a cannot be rotated while the automatic mode is activated, a previously set individual rotary position of the control element 3, 3a cannot be changed in the automatic mode. After the automatic mode is deactivated, the control element 3, 3a is therefore automatically located back in the previously manually set position. A new manual setting procedure is thus obviated.
Instead of an axially arranged switch or push-button key, a Hall sensor with an appropriate magnet may be provided for registering the automatic operating function of the air conditioning system. Instead of a rotary potentiometer 6 for manually setting the respective operating function area, it is also possible to provide radially arranged keys which can be activated incrementally by means of a cam, so that incremental adjustment is made possible. In the same way, a visual detection means may be provided which counts corresponding rotary pulses. In this embodiment, a memory unit which counts the rotary pulses is then additionally necessary. The respective electronic components act on corresponding digital or analogue switching inputs of the control unit 10.
In the illustrated exemplary embodiment, the manual setting of the operating function is effected by a rotary movement of the control element. In the same way, a control 7 element f or manual setting can, however, also be displaced linearly in the plane of the control panel. The axial pressing-in in order to activate the automatic function then corresponds, for the rest, to the previously described exemplary embodiment.
