Definitions
- the invention relates to a pedal device, in particular for a motor vehicle, with an actuating element for actuating a function by a user and a positioning device for positioning the actuating element in a first position and a second position. Furthermore, the invention relates to the use of such a pedal device in a motor vehicle.
- Pedal devices are used in motor vehicles, such as passenger cars or trucks, with which a driver as a user can accelerate or brake the motor vehicle or vehicle.
- a brake pedal is provided in a footwell of the vehicle as a pedal device for braking and an accelerator pedal or gas pedal is provided as a pedal device for accelerating. Both the brake pedal and the accelerator pedal protrude from a floor surface providing foot space by means of a pedal rod.
- a pedal step surface is arranged transversely to the pedal rod. The user exerts pressure with his foot on the respective pedal surface as required and thus moves the pedal surface and the pedal rod coupled thereto from an initial position into a working position.
- a braking function is thus achieved with a vehicle brake system coupled to the brake pedal and an acceleration function is achieved with a vehicle drive coupled to the gas pedal.
- the pedal surface is pushed back from the working position to the starting position by means of the pedal rod and a resilient support.
- Further developments in vehicles offer new possibilities for the design of such pedal devices. New requirements are also made.
- Such further developments are, for example, brake-by-wire systems, in which a pedal and a brake are coupled by purely electronic signal transmission, autonomous driving and electrically powered vehicles.
- the invention is based on the object of creating a reliable pedal device with which a function, in particular a braking function or an acceleration function, can be provided in a motor vehicle.
- a pedal device is created, in particular for a motor vehicle, with an actuating element for actuating a function by a user and a positioning device for positioning the actuating element in a first position and a second position.
- the first position of the actuating element is flush with or below or slightly above a surface formed by means of the surroundings of the actuating element and the second position of the actuating element is further above the surface formed by means of the surroundings of the actuating element compared to the first position.
- the actuating element is therefore intended to be operated or actuated by a user of the vehicle when the user wants to achieve a specific function.
- the function is preferably a braking function or an acceleration function.
- the braking and acceleration function is particularly preferably provided with only one actuating element.
- the actuating element is arranged in a footwell on a driver's side of the vehicle on its front floor area.
- the actuating element is surrounded in its surroundings or in its surrounding area by a surface or surrounding surface. Relative to this surface, the actuating element is flush or below or slightly above the surface in the first position and above or further above the surface in comparison to the first position arranged.
- the second position of the actuating element is that position in which the user can operate the actuating element and thus represents its starting position.
- the user can touch the actuating element as a pedal with his foot and exert pressure on it. This urges the actuator into a working position toward the surrounding surface, causing a function in the vehicle.
- the first position of the actuating element is a rest position, in which the actuating element is arranged flush or below, in particular slightly below, or slightly above the surrounding surface.
- a space surrounding the actuating element thus has more space.
- the space is the footwell on the driver's side of the vehicle, which is then more spacious in its front area.
- the user's foot cannot catch on the actuating element in such a rest position.
- the actuating element is particularly preferably arranged flush with the surrounding surface. This creates a level surface without steps that is particularly easy to keep clean. Furthermore, the actuating element is preferably arranged slightly or slightly above the surrounding surface in the first position. A small projection is thus created, by means of which the user can clearly see where the actuating element to be operated is located without the risk of getting caught. In comparison to the first position, the actuating element then lies further above the surrounding surface in the second position and is therefore arranged to protrude more clearly or to a greater extent.
- a positioning device coupled to the actuating element is provided for changing the position of the actuating element.
- the positioning device is adapted to bring the actuating element into the first and the second position as required.
- at least one intermediate position between the first and the second position of the actuating element is preferably provided as required.
- the actuating element is advantageously designed in the form of a block. This creates a solid pedal block that has a stable contact surface and has a particularly good power-transmitting effect. Occurs When the user acts on the block-shaped actuating element, a force exerted therewith is distributed over the block and transmitted particularly extensively to a transmission and actuating device coupled to the actuating element.
- the actuating element can be brought into the second position without undercuts from the surrounding surface and is positioned there without undercuts.
- a block-like actuating element is designed as a pedal block that can be moved out of the surrounding surface. This means that in the event of an accident or crash, nothing can slip under the actuating element. A snagging with the actuating element is also prevented. In addition to this increased safety, the footwell can easily be kept clean.
- the actuating element and its surroundings are covered with a flexible surface element such that when the actuating element is positioned in the second position, the flexible surface element can be moved out of the surface formed by the surroundings of the actuating element by means of the actuating element.
- the flexible surface element then protrudes from the surface in the area of the actuating element.
- the actuating element rests against the surface element below the flexible surface element and is located together with the surface element in the second position above the surrounding surface.
- the actuating element and its surroundings are covered with the surface element in such a way that the actuating element and its surroundings are flush with one another. A flat surface without a projection is created.
- a visible marking is preferably attached to the surface element in the area of the actuating element in the flat surface.
- the actuating element is arranged slightly below or above its surroundings and is covered by the surface element together with the surroundings. This creates a surface with a small depression or only a slight protrusion as a distinguishing feature.
- the flexible surface element has a visible side and an inner side opposite the visible side, which is applied to the actuating element and its surroundings. This creates a largely flat visible side in the first position and a visible side with a structure in the second position, in which an actuating area protrudes from the surrounding surface in the area of the actuating element.
- the positioning device when the actuating element is positioned in the second position by means of the positioning device, the actuating element with the surface element protrudes from the surrounding surface.
- the positioning device, the actuating element coupled thereto and the flexible surface element function as a movable surface which protrudes from an otherwise flat surface.
- Such a surface is also referred to as a morphing surface.
- the flexible surface element is preferably designed with a textile material and/or with a rubber-like material. This achieves particularly good deformability and adaptation to the actuating element in its respective position.
- the positioning device is advantageously adapted to bring the actuating element into the second position as soon as an associated mode is activated.
- the mode is preferably a situation in which the user touches the actuating element directly or by means of the flexible surface element.
- the mode is already closed activate when the user gets close to the actuating element or when a corresponding posture is detected. In this way, the actuating element can be brought into the second position and thus into the starting position required for work to be carried out in advance. An associated function can then be triggered particularly quickly.
- the associated mode is particularly preferably an activated mode in which the driver wants to operate the vehicle himself or, depending on the system, should take over control.
- the actuator In this activated mode, the actuator is in the second position and can be actuated by the driver as needed.
- the actuating element is arranged in an inactive or autonomous mode in the first position at the level of the surrounding surface. The actuating element is thus invisible in the inactive mode and designed to morph out of the environment in the activated mode. Designed in this way, a particularly comfortable footwell with plenty of space and without annoying pedals with an attractive design and particularly high safety standards has been created. The demands of the driver on such aspects are growing, especially with an increasing proportion of autonomy in the journey.
- the surface brought out by activation provides haptic feedback with which the driver, who may only want or need to take control for a short time, gains a feeling of the applied force, which is translated into actuators.
- a detection device for detecting a touch of the actuating element and/or a movement in the direction of the actuating element is also advantageously provided for activating the associated mode.
- the actuating element can be touched either directly by the driver or indirectly by means of the surface element at its actuating area covering the actuating element.
- the detection device is preferably designed with a camera sensor which uses image recognition to detect whether the actuating element is being touched or whether the user is approaching the actuating element.
- the detection device is preferably designed with a proximity sensor for detecting when the user is approaching the actuating element. With that can already at a certain distance of the user from the actuating element, the activated mode is switched on and the actuating element is brought into the second position.
- the detection device is particularly preferably designed with a capacitance sensor.
- a capacitance similar to a capacitive touch screen can be determined on the surface element or the actuating element.
- the detection device is preferably designed in a simple manner in terms of production engineering with a pressure sensor that detects pressure exerted on the actuating element by the user.
- the detection device is particularly preferably a combination of the sensors mentioned or a part of the sensors mentioned. In this way, the detection device can be designed in a particularly needs-based manner.
- the positioning device is advantageously designed with a pneumatic device.
- a pneumatic actuator is preferably provided for this purpose, which in particular has a gas cushion with a variable volume.
- the gas cushion is preferably an air cushion at low cost.
- the actuating element can be moved accordingly, depending on its volume change.
- the advantage here is that such a movement can be controlled very precisely in terms of path and speed. This means that an extension movement of the actuating element into the second position and a retraction movement into the first position can be produced very precisely and gently without jerky movements. In addition, these movements on the gas cushion or actuator are almost silent if a required pump is installed accordingly.
- the pneumatic actuator itself requires very little installation space, which benefits freedom of movement in the footwell.
- the pneumatic actuator is preferably used at the same time as a pressure sensor for a pressure to be exerted by the user on the actuating element. If the gas cushion or the actuator is filled or inflated with gas, then the actuating element or the pedal is extended and can be operated. In this case, a pressure on the pedal due to an increase in air pressure in the actuator can be detected particularly precisely, if necessary via a compensation volume. In addition, a haptic feeling of operation is retained as with a classic pedal. A very compact, robust and cost-effective actuator-sensor system is thus created.
- the pneumatic device is particularly preferably designed with an antagonistic double actuator.
- two gas cushions lying one above the other are provided, of which one cushion is always inflated by appropriate storage and the other cushion contains correspondingly less gas.
- the other cushion is largely empty. If the initially empty cushion is filled with gas, the volume of the empty cushion increases while the volume of the initially inflated cushion decreases. If the cushion with decreasing volume is assigned to the actuating element, then the actuating element is moved back into the first position. To extend, the cushion with a reduced volume is filled with gas, increases in volume again and thus moves the actuating element into the second position.
- the gas is preferably not pumped directly from one cushion into the other cushion, but particularly preferably by a pump into the respective cushion. The gas then escapes from each filled cushion through a respective associated valve. With this antagonistic double actuator principle, the actuating element can be brought into the respective position in a controlled, compact, robust, cost-effective and quiet manner.
- the positioning device is advantageously designed with an electromechanical device, which preferably has a servomotor.
- a position of associated components can thus be changed mechanically with an electric motor as the control element as required and efficiently so that the actuating element can be brought into the respective position alternately.
- the positioning device is preferably designed with an electromagnetic device or with an electromagnetic actuator.
- the positioning device is thus particularly easy to control and at the same time takes up particularly little installation space.
- the positioning device is advantageously designed to be even more space-saving with an actuator material, preferably with a shape-memory material.
- a shape-memory material preferably shape memory alloys (FGL, shape memory alloy, SMA). These are special metals that occur in two different crystal structures. A phase transition between the two crystal structures preferably takes place by means of a temperature change and particularly preferably by means of a mechanical stress. This achieves a deformation that returns to its previous shape even if it is severely deformed.
- the shape-memory material preferably forms the actuating element or pedal or the plate surface by means of a temperature change and/or a magnetic field.
- the positioning device is thus advantageously designed with a thermally and/or magnetically controlled device.
- a high-temperature phase called austenite can be achieved with an increase in temperature of the shape-memory material, and a low-temperature phase called martensite can be achieved with a temperature decrease.
- Two crystal structures are possible within the martensite phase, which transition into one another as a result of heating and subsequent cooling (austenite-martensite transition).
- a magnetically excitable shape-memory alloy can also be used, in which a shape change occurs due to an external magnetic field.
- Such magnetic shape memory alloys are referred to in English as magnetic shape memory alloy (MSMA).
- a nickel-titanium alloy (NiTi, Nitinol) and particularly preferably a nickel-titanium-copper alloy (NiTiCu) is preferably used as the shape memory alloy.
- Such alloys have a particularly good shape memory.
- a respectively associated transition temperature for the austenite-martensite transition is dependent on a quantitative ratio of the individual metals to one another.
- a pseudoelastic or pseudoplastic behavior at room temperature can be generated by varying the quantity ratio or the stoichiometry.
- a copper-zinc alloy (CuZn), copper-zinc-aluminum alloy (CuZnAl) and/or copper-aluminum-nickel alloy (CuAlNi) is also preferably used as the shape memory alloy. Such alloys are particularly inexpensive.
- An iron-nickel-aluminum alloy (FeNiAl), iron-manganese-silicon alloy (FeMnSi) and/or zinc-gold-copper alloy (ZnAuCu) can also be used.
- a shape memory polymer (FGP, shape memory polymers, SMP) is particularly preferably used as the shape memory material. Thanks to their low thermal conductivity, such polymers have particularly short switching times.
- the shape-memory polymer is preferably excited by means of heating above an associated switching temperature.
- the shape-memory polymer is particularly preferably a polymer that can be excited by light of a specific wavelength.
- the crosslinks can be detached by irradiating them with a different wavelength in such a way that they are restored to their original shape.
- the positioning device is advantageously designed with a light-induced controlled device with such a shape-memory polymer. The positioning device can thus be controlled particularly quickly and in an energy-saving manner.
- the positioning device is advantageously designed with a magnetohydrodynamically controlled device.
- a metal alloy that is liquid at room temperature or a liquid metal in particular GalnSn (gallium, indium, tin), has advantageously proven particularly suitable for this purpose.
- GalnSn gallium, indium, tin
- the liquid metal thus preferably serves as a sensor at the same time.
- the positioning device is preferably designed with a magnetohydrodynamic liquid metal actuator, in which a pressure can be controlled by means of electrical activation of the liquid metal.
- a flexible surface is formed by means of various individual surface elements that can be controlled differently, of which at least one individual surface element serves as an actuating element.
- Such a magnetohydrodynamic device can be triggered electrically, whereby the liquid metal moves in one direction and thus exerts pressure on a surface.
- a series connection is preferably used to increase the pressure.
- Many individual elements are particularly preferred provided, which are designed in particular as small pin surfaces. The many elements together form the actuating element or pedal and can be controlled differently as required. By means of a different and successively increasing extension height of the individual elements, a flat pedal then changes into an inclined pedal.
- the elements are preferably covered with a flexible surface element or with a support plate in a particularly stabilizing manner.
- the function to be actuated with the actuating element is preferably a braking function.
- This enables particularly safe braking even with open shoes, such as flip flops. Especially in emergency braking situations, safety is significantly increased with such a brake pedal. Furthermore, other advantages already mentioned are achieved.
- the function to be actuated with the actuating element is advantageously an acceleration function. This also enables particularly safe acceleration.
- the advantages already mentioned are also achieved with such an accelerator pedal.
- the function to be actuated with the actuating element is a braking and acceleration function, depending on the requirement, in a particularly advantageous manner.
- only one pedal device is provided in future in electric vehicles, with which the acceleration and braking is taken over by recuperation.
- a braking process is to be triggered by recuperation by releasing the actuating element.
- Emergency braking is preferably recognizable by a very strong pressure exerted by the driver, whereas only little pressure is necessary for acceleration.
- a force exerted by the driver on the actuating element and measured by a corresponding sensor system is particularly preferably forwarded by means of a brake-by-wire device to a corresponding actuator system, such as a brake or acceleration device.
- a corresponding actuator system such as a brake or acceleration device.
- an emergency brake assistant is preferably provided as a further driving function, with which redundant automatic emergency braking can be achieved as an additional safety aspect.
- a second actuating element which is morphable according to the invention and which can be actuated as an emergency brake is particularly preferably provided.
- the invention relates to the use of such a pedal device in a motor vehicle, preferably as a brake pedal and/or accelerator pedal.
- the pedal moves out of a floor surface of a vehicle footwell without an undercut and only when necessary, with the result that a particularly high level of safety when driving is achieved.
- there is plenty of space in the footwell which gives the user's legs plenty of freedom of movement. Requirements for a minimalist design are also met, which can be used to avoid dangerous distractions when driving the vehicle.
- FIG. 1 shows a schematic cross section of an exemplary embodiment of a pedal device according to the invention in the retracted state
- FIG. 2 shows the view according to FIG. 1 in the extended state.
- the pedal device 10 can be used to actuate a braking function and an acceleration function as required.
- the pedal device 10 comprises a pedal block or a block-shaped actuating element 12 which is completely covered with a flexible surface element 16 in the direction of an interior space 14 of the vehicle which is only indicated.
- the flexible surface element 16 has a visible side 18 facing the interior 14 and an inner side 20 opposite the visible side 18 .
- the inner side 20 rests against the actuating element 12 and additionally against a surrounding surface or surface 24 formed by means of a surrounding area 22 of the actuating element 12 .
- the flexible surface element 16 thus covers the surface 24 and the actuating element 12.
- the actuating element 12 is arranged flush with the surface 24 in a first position 26, so that the visible side 18 of the flexible Surface element 16 is designed flat (Fig. 1). Designed in this way, there is a particularly large interior 14 without a floor step in the first position 26 .
- the first position 26 is a rest position in which the actuating element 12 cannot be actuated or operated by a user of the vehicle.
- a detection device 28 which in the present case is a combination of camera sensor and pressure sensor. From there, a detected signal is forwarded to a control device 30 which is coupled to a positioning device 32 in a signal-transmitting manner.
- a mode 34 is activated.
- the actuating element 12 is brought from the first position 26 into a second position 36 with the positioning device 32 .
- the second position 36 is above the surface 24 (FIG. 2).
- the actuating element 12 moves out of a plane of the surface 24 and highlights the flexible surface element 16 in the region of the actuating element 12 .
- the visible side 18 thus has a structure in which an actuating region 38 protrudes from the surface 24 in the region of the actuating element 12 .
- the pedal device 10 creates a morphing surface in which a three-dimensional pedal emerges from the surface 24 as an actuating element 12 as soon as the user approaches.
- the actuating element 12 can be operated by the driver as a pedal.
- a braking or accelerating function is transferred to a braking or accelerating device (not shown) by exerting pressure.
- a transmission and control device also not shown, is provided, which can be a hydraulic system or a brake-by-wire system.
- the positioning device 32 is designed as a pneumatic device 40 with an antagonistically acting, pneumatic double actuator.
- the device 40 comprises a first air cushion 42 arranged below the actuating element 12 and a second air cushion 44 arranged below the first air cushion 42.
- the two air cushions 42 and 44 each act as an air pocket for mutually absorbing air.
- air is taken up in the two air cushions 42 and 44 overall in a predefined volume of air that is delimited by the air cushions 42 and 44 .
- the air contained in the air volume can be moved back and forth between the two air cushions 42 and 44 as required.
- a line 46 that connects the two air cushions 42 and 44 in an air-conducting manner and a shut-off element 48 that is arranged in the line 46 and can be opened or closed as required is provided.
- a first movement element 52 that can be displaced back and forth along an axis 50 is arranged above the first air cushion 42 between the first air cushion 42 and the actuating element 12 .
- the movement of the first movement element 52 is coupled to the actuating element 12 .
- the first movement element 52 is associated with the first air cushion 42 and, depending on the change in volume of the first air cushion 42 , is guided in a displaceable manner axially with respect to the axis 50 in the direction and counter to the direction of the actuating element 12 .
- two guide elements 54 are provided which extend parallel to the axis 50 and are each arranged on the outside of the first movement element 52 .
- the first movement element 52 is presently designed as a plate which extends transversely to the axis 50 and which is displaceably mounted on the guide element 54 on two of its opposite outer sides 56 .
- a plate-shaped fixed element 58 extending transversely to the axis 50 is provided axially between the first air cushion 42 and the second air cushion 44 .
- the fixed element 58 is fixed statically and is therefore not arranged in the pedal device 10 such that it can be moved.
- an associated second movement element 60 is arranged axially below the second air cushion 44, which is also designed as a plate and is attached to the outside of the two guide elements 54 is guided axially displaceable. The second air cushion 44 is thus clamped between the second moving element 60 and the fixed element 58 .
- the second air cushion 44 is filled with significantly more air than the first air cushion 42 .
- the second movement element 60 is displaced in the direction of the fixed element 58, the second air cushion 44 is compressed.
- the air contained therein is thus forced through the line 46 into the first air cushion 42 when the shut-off element 48 is open.
- the first air cushion 42 is clamped between the fixed element 58 and the first moving element 52 .
- the air urging or flowing into the first air cushion 42 displaces the displaceably arranged first movement element 52 axially in the direction of the actuating element 12.
- the actuating element 12 is thus moved correspondingly axially upwards into the interior space 14 into its second position 36 shifted according to FIG. In the process, the flexible surface element 16 is lifted upwards out of the surface 24 in the actuation area 38 .
- the pedal device 10 can be actuated by the driver by means of the actuating element 12 .
- an air pressure present in first air cushion 42 is increased, which air pressure is detected by a pressure sensor (not shown) and/or alternatively by a compensating volume (not shown).
- a braking or acceleration process is triggered.
- the acceleration process requires less pressure from the user and thus less air pressure increase in the first air cushion 42.
- the pneumatic device 40 used as the positioning device 32 also serves as a transmission device with which the desired braking or acceleration function is transmitted to a respective associated actuating device is transferrable.
- the second air cushion 44 is again filled with air from the first air cushion 42 .
- the second movement element 60 is moved axially downwards and thus away from the actuating element 12 .
- the second air cushion 44 is filled with air from the first air cushion 42 through the line 46 .
- the second air cushion 44 thus increases in volume.
- the volume of the first air cushion 42 decreases accordingly, so that the first movement element 52 and, coupled thereto, the actuating element 12 are displaced in the direction of the fixed element 58 . In this way, the actuating element 12 is moved back into its first position 26 until a flat visible side 18 is formed again with the surface element 16 .
- control device 30 coupled to the detection device 28 is coupled to at least the shut-off element 48 in a signal-transmitting manner.
- a signal-transmitting coupling to the second movement element 60 is also provided.
- each air cushion 42 and 44 is assigned its own valve, with which air can be released from the associated air cushion 42 or 44 to the outside.
- a central pump is provided, through which air can be pumped alternately from the outside into the first air cushion 42 and into the second air cushion 44 .
- the actuating element 12 is thus brought from the first position 26 analogous to FIG. 1 into the second position 36 analogous to FIG.
- the second air cushion 44 is to be filled with air by the central pump, while air is to be released from the first air cushion 42 through the associated valve.
