Definitions
- Control device for installation in a vehicle
- the invention relates to an operating device for installation in a vehicle.
- Control devices for installation in a vehicle are known in a wide variety of configurations. Such operating devices have, for example, individual depressible buttons, slide switches, toggle or rocker buttons and / or push / turn controls. What all these control elements have in common is that a certain previously structurally fixed actuating force threshold must be exceeded manually in order to trigger an operating function or, in the case of a rotary actuator, to continue turning it manually.
- latching adjustable controls such as a turntable
- a control element with adjustable haptics is known from DE-A-10 2008 060 256.
- the locking positions cannot be changed.
- DE-A-10 2018 217 865 describes an operating device with a compensating mass which supports the return movement of the depressed operating element after it has been actuated into its starting position.
- the object of the invention is to create a simple concept for an operating device for installation in a vehicle, in which the operating element or elements can be varied in a simple manner with regard to their manually overcome force threshold or force thresholds.
- the invention proposes an operating device for installation in a vehicle, the operating device being provided with a housing, an operating element movably mounted in and / or on the housing, which can be manually transferred from a rest position to a function release position, a switch that can be actuated by the control element when it is manually transferred into the function release position, a holding force generating unit for generating a holding force with which the control element is held in its rest position, and a control unit for the electrical control of the holding force generating unit for the purpose of setting a maximum holding force, which can be lowered when the operating element is touched in order to produce the haptics typical for operating an operating element.
- the operating device has at least one operating element which is movably mounted in and / or on the housing and can be manually transferred from a rest position to a function triggering position.
- the control element is assigned a switch which can be actuated by the control element when it is manually transferred into the function trigger position.
- the switch can work purely mechanically, but it can also be designed as an optical, capacitive or ductile switch.
- a holding force generating unit is assigned to each operating element, with which the holding force with which the operating element is held in its rest position can be adjusted.
- the holding force generating unit thus determines the force threshold which must be overcome manually for valid actuation of the operating element; the holding force generating device does not lead to a fundamental blocking of the control element, which consequently can continue to be pressed down by manual actuation if the force threshold is exceeded, but this is basically not intended for the operation of the control element.
- a control unit which generates an electrical control signal for each holding force generating unit that defines the set holding force.
- a different force threshold can now be specified for several control elements, which must be overcome manually in order to be able to validly actuate the control element in question.
- an operating device for installation in a vehicle can be personalized, so to speak.
- the force thresholds of the operating elements can be specified differently depending on the menu.
- the control unit and the holding force generation unit can also be used to set the dynamics with which the control element can be actuated.
- the force-displacement characteristic of an operating element can be changed not only statically, but also dynamically.
- the holding force generating unit has an electromagnet, which has a stator with an electrical coil and an armature, and that the control unit for controlling the electrical coil of the electromagnet is connected to it.
- the force threshold can be defined particularly advantageously and easily, for example via the size of the coil current and / or the air gap between the stator and armature and / or the extent to which the magnetically effective surfaces of the stator and armature overlap .
- the fact in which direction the stator and armature move relative to one another when the set force threshold has been overcome can also play a role in the size and adjustability of the force threshold.
- the stator and armature can move further apart at this moment, so the air gap can change, or the air gap remains the same and the stator and armature move transversely to their spacing.
- a coil current is required, that is to say the application of electrical energy, in order to define the holding force in the rest position of the operating element.
- the use of a permanent electro-holding magnet as a holding force generating unit is possible.
- the magnetic holding force is provided by the magnetic flux generated by the permanent magnet.
- the Hal tekraft can also be set by choosing the permanent magnet.
- the control device can have a touch sensor system for detecting a touch of the control element, the touch sensor system outputting a sensing signal to the control unit when the control element is detected and the control unit then outputs the holding force generating unit for setting a desired, controls holding force acting in the rest position of the touched control element.
- a holding force can be specified in the rest position of the operating element, which is only reduced to the desired level (typically reduced) at the moment when touching the operating element is detected.
- a “rattling” of the operating element can thus be prevented without excessively large forces having to be overcome when the operating element is operated manually.
- the control element has a user interface with several control panels, that the touch sensor system outputs different sensor signals to the control unit as a function of the control panel for which a touch is detected, and that the control unit outputs the holding force Generating unit depending on the different sensing signals for the purpose of generating different holding forces with different control signals controls.
- the force threshold with which the control element must be depressed to activate the function that can be triggered with the relevant control panel can be of different sizes.
- this holding force can also be the same for each of the operating panels and different or the same from operating menu to operating menu.
- the (typically) lowering of the holding force when the control element is touched can therefore be of different sizes for different control panels of one and the same control menu or the same for all control panels of the control menu and different from control menu to control menu for the respective control panels or consist of a combination of both.
- the holding force is when the control element is not touched large enough so that a rattle or an unintentionally strong and forceful touch of the operating element does not immediately trigger an operating function.
- these can also have a magnetorheological or an electropolymeric holding force element (see e.g. DE-B-10 2018 212 618), this type of holding force elements in turn being controllable with electrical control signals that are generated by the control unit of the invention Control unit can be generated.
- Such holding force elements can, for example, be designed as mechanical blocking elements and, in a "solidified” state, make it difficult to move the operating element or an element kinematically coupled to it, while they are / become flexible when the force thresholds are overcome. This is because magnetorheological polymers or fluids can change their stiffness or mobility under the influence of an externally applied magnetic field, as is also the case with electroactive polymers when electrical voltages are applied.
- blocking elements can also work pneumatically or hydraulically.
- particles or elements that can be brought into a form fit can be placed in a casing or the like.
- the mobility of the edging can be influenced by pneumatically or hydraulically applied negative pressure.
- the at least one operating element which is electrically adjustable with regard to its force threshold within the scope of the operating device according to the invention, can be linearly guided and thus translationally movable from the rest position into the function triggering position.
- Such an operating element is designed, for example, as a button, that is to say can be moved vertically, or is designed as a slide switch, the operating element then being laterally displaceable.
- the at least one operating element can also be tiltable or pivotable and thus by tilting or pivoting from the rest position into the function trigger position be transferable.
- the holding force can also be influenced by the selected leverage ratio.
- the switch can be a mechanical switch or a contactless switch, for example an optical, capacitive or inductive switch. If a mechanical switch is used, its haptics are used in addition to the haptics generated by the holding force set according to the invention. In the case of non-mechanical switches, the haptics can then be implemented solely by the holding force generating unit provided according to the invention.
- the return movement of the actuated control element in its rest position can be spring-assisted or assisted by balancing weights or also by the resilience of a device when it is pressed down, for example. Pressing the control operated switch take place.
- the holding force generating device and the magnetic force typically used by it can also be used to "pull" the operating element back into the rest position.
- FIG. 1 schematically shows a first exemplary embodiment of an operating device with an operating element designed as a touchscreen, which can be depressed
- FIG. 2 shows a second exemplary embodiment of an operating device with a toggle switch
- FIG. 3 shows a schematic representation of a permanent electro-adhesive magnet.
- an operating device 10 for installation in a vehicle is shown in section and in perspective, which element has a housing 12 with an operating element 14.
- the operating element 14 is designed as a touchscreen which forms a user interface 16 on which a plurality of operating fields 18 are displayed.
- the operating element 14 is held by means of a holding force generating unit 26, which has two permanent electro-holding magnets 28 in this embodiment.
- a single such permanent electro-holding magnet 28 is also sufficient.
- a permanent electromagnetic holding magnet 28 (see, for example, FIG. 3) also has an electrical coil in addition to a permanent magnet.
- the electrical coil is controlled with the aid of an electrical control signal 30 that is generated by a control unit 32.
- the control unit 32 is also supplied with a sensing signal 34 from the touch sensor system 36 of the touchscreen.
- Fig. 1 the structure of the operating device 10 is shown purely schematically.
- the holding force in the rest position of the operating element 14 shown in FIG. 1 is generated by the two permanent electromagnets 28 of the holding force generating unit 26.
- the size of the air gap and the choice of permanent magnets play a role here.
- a control signal 30 is sent to the electrical coils of the permanent holding magnets 28 via the control unit 32, so that their force threshold adjusts to the level that is desired and must be overcome manually to depress the control element 14.
- the switch 22 is then actuated.
- Fig. 2 a modified concept of an operating device 10 'is shown with alter native operating element 14'.
- the operating element 14 ' is designed as a toggle button and has a tilt or pivot bearing 37.
- the elements of the operating device 10 'of FIG. 2 essential for the invention are structurally or functionally comparable with those elements of the operating device 10 of FIG. 1, they are given the same reference characters in FIG. 2, but simply deleted.
- the holding force generating unit 26 'of the operating device 10' of FIG. 2 in turn has a permanent electromagnetic holding magnet 28 '. Due to the tilting or swiveling construction of the operating element 14 ', the holding force of the rest position of the operating element 14' shown in FIG. 2 can now be influenced with an appropriate selection of the lever ratios, thus providing a further degree of freedom.
- a permanent Elektrohaftmag shown schematically in Fig. 3 designated 28 as a holding force generating unit 26 is also advantageous insofar as the movable armature 38 and the stationary stator 40 of the holding magnet do not touch in the holding position, but through a minimal air gap, for example 42 remain separate from each other.
- the gap 42 could also be filled with mechanically steaming, ie for example compressible, material. So there is no contact between armature 38 and stator 40 and thus no possible mechanical force reaction on the operator surface 16, which would affect comfort.
- the stationary stator 40 or else the movable armature 38 is provided with a permanent magnet 44.
- the stator 40 also has a coil 46 through which current flows in order to cancel, change, redirect, or the like, the magnetic field emanating from the permanent magnet 44 and affecting the maintenance of the position of the armature 38. If the finger of a hand is detected via the touch sensor system 36, which is classically a touch sensor system, then the coil 46 of the permanent electro-holding magnet 28 can be energized and the holding force can be changed or even canceled. This takes place within a few milliseconds and is there- with outside of perceptible latency.
- the construction according to the invention therefore allows the passive haptic concept to be implemented comfortably in a simple manner.
- This is characterized in that a depressible operating element 14 'acts on a mechanical switch 22, which has a tactilely perceptible force acting back on the operating element 14'.
- the operating element 14 ' has a large number of symbol fields.
- the entire user interface 16 is not always occupied by symbol fields. For example, “isolated touch areas” can be identified on the user interface 16. There is no function between these isolated surfaces. Without mechanical locking, however, the user interface 16 can move when a force is applied by a finger and thus suggest a non-existent function triggering.
- the controllable mechanical lock according to the invention prevents this.
- the lock is only released when the finger is on the designated touch surfaces.
- the lock can only be released temporarily for designated touch surfaces. This can prevent a touch surface that is basically enabled from being rendered ineffective due to previously defined operating states, for example of a vehicle.
