Description

Technical Field

[0001] The invention relates to a pedal assembly for a vehicle. Background Art

[0002] Drive-by-wire systems with pedal assemblies are known from the prior art, which transmit the driver's commands only electrically or electronically. Such drive-by-wire systems include, for example, a pedal assembly with a so-called electronic accelerator pedal or accelerator pedal for drive control or acceleration functions and a brake pedal for a brake-by-wire system to supply brake energy. Another known drive-by-wire system is a steer-by-wire system for steering control. Drive-by-wire means driving or controlling a vehicle without a mechanical force transmission from an operating element of the vehicle, such as an accelerator pedal, a brake pedal or a steering wheel, to corresponding adjustment elements of the vehicle, such as a throttle, brakes and / or steering of the vehicle. This means that, for such drive-by-wire systems, the corresponding pedal unit is decoupled from the force flow and the aforementioned functions are controlled instead by electrical cables and servomotors or electromechanical actuators. Usually, the sensor device of the drive-by-wire system detects the driver's predefined conditions by means of a force-based sensor unit in order to determine the required braking or acceleration intensity of the vehicle and to set this braking or acceleration intensity accordingly via the drive train and the brake system. The elimination of the mechanical connection enables novel pedal concepts, since a long pedal travel is no longer required to decelerate or accelerate the vehicle.

[0003] Patent document DE 103 12 547 A1 discloses a device for accelerating or decelerating a motor vehicle, which device comprises two operating elements. The first operating element is used to accelerate the motor vehicle and the second operating element is used to decelerate the motor vehicle. These operating elements are operated by applying hand force or foot force. Here, the two operating elements work largely without stroke and the speed of the motor vehicle is kept constant by the first operating element or the second operating element according to the last applied hand force or foot force after the hand force or foot force is cancelled until further operation of the first operating element or the second operating element is performed.

[0004] Patent document DE 102 39 913 A1 discloses an operating mechanism for influencing a braking, clutching or driving device of a motor vehicle. The operating mechanism operated by the driver is mechanically decoupled from the actuator of the device. Here, the operating mechanism is a receiver that only detects the operating force of the driver and generates a control signal, the generation of which is independent of the operating path and has no operating path.

[0005] Patent document DE 10 2023 204 205 A1 subsequently disclosed by the applicant discloses a pedal assembly having two pedal units, a pedal unit for triggering a vehicle function, and a method for assembling such a pedal unit and a method for removing a pedal head from such a pedal unit. The pedal unit includes a pedal head of modular construction, which includes a pad carrier and a replaceable pedal pad for receiving the operating force of the driver's foot, and is connected to a housing cover, which can be moved with a small stroke in the height direction of the pedal unit. The pedal pad is detachably connected to the pad carrier. Here, a fixing assembly detachably connects the pad carrier to the movable housing cover in a form-fitting and / or force-transmitting manner. The pedal assembly includes a first pedal unit configured as a brake pedal and a second pedal unit configured as an accelerator pedal. Summary of the invention

[0006] The pedal assembly for a vehicle having the features of independent claim 1 has the following advantages: Due to the special positioning between the two pedal units, the common feedback assembly can output a haptic feedback signal to the driver via the two pedal units. By positioning the feedback assembly in this way, the haptic feedback signal can be transmitted to the driver's foot via a first pedal unit, for example, which is designed as an accelerator pedal, for triggering an acceleration function, and via a second pedal unit, for example, which is designed as a brake pedal, for triggering a braking function. For a brake pedal for triggering a braking function, this haptic feedback signal can be used, for example, for the currently ongoing adjustment of an anti-lock braking system (ABS) to the driver's foot. For an accelerator pedal for triggering an acceleration function, for example, a signal can be sent to the driver that his intention for a downshift (Beschleunigungs-Kick-Down) has been recognized. The haptic feedback signal can be influenced in terms of signal form and / or signal duration and / or intensity by corresponding trigger signals. These trigger signals can be predetermined and adjusted, for example, by the vehicle manufacturer and / or the driver.

[0007] In addition, positioning the feedback assembly at a common holding element has several additional advantages. For example, a larger motor or driver can be used for the vibration device of the tactile feedback assembly, and its rotation speed can be better adjusted to the driver's optimal sensing range compared to a smaller motor or driver. For example, a larger motor or driver can be used to generate a particularly strong tactile feedback signal in winter so that the driver can perceive the tactile feedback signal even if wearing thick shoes. In addition, a larger motor or driver of a vibration device can usually run at a lower rotation speed and therefore run quieter than a high-speed vibration device. In addition, at a lower rotation speed, it is also easier to soundproof the passenger. In addition, the feedback assembly can be positioned by connection with the common holding element, preferably positioned below a support member, which, for example, includes a sound-absorbing element and / or a foam filler and is arranged between the holding element and a foot pad, from which the pedal heads of the two pedal units protrude. Soundproofing for passengers and drivers can thus be improved. Ideally, the driver will only feel the vibration of the pedal unit he manipulates, and the passenger should preferably not hear any sound. Since only one feedback assembly is used for two target elements, cost and weight can also be reduced. Preferably, the common holding element can be designed with a more vibration-resistant design in such a way that the haptic feedback generated by the feedback component is not excessively dampened. It is also conceivable to mount the common holding element on the vehicle body in a vibration-decoupled manner.

[0008] An embodiment of the present invention provides a pedal assembly for a vehicle, the pedal assembly having two pedal units and a common holding element, through which a vehicle function can be triggered respectively, the holding element having two receiving openings. The two pedal units are respectively inserted and held in corresponding receiving openings of the common holding element. Here, the common feedback assembly is arranged between the two receiving openings of the common holding element or integrated into the common holding element, and the common feedback assembly generates a predeterminable tactile feedback and outputs the tactile feedback to the driver's foot via the common holding element and the two pedal units.

[0009] Advantageous developments of the pedal arrangement for triggering a vehicle function specified in independent claim 1 are achieved by means of the measures and developments listed in the dependent claims.

[0010] It is particularly advantageous if the common feedback arrangement conceivably comprises a vibration device which generates a vibration signal with an adjustable frequency and / or adjustable intensity and outputs it to the driver's foot via the common holding element and the two pedal units.

[0011] In an advantageous embodiment of the pedal assembly, the vibration device can be designed as a vibration motor with at least one eccentric mass or as a linear resonant actuator. A vibration motor is understood here to be a rotating electric motor, on whose shaft at least one mass is mounted as an eccentric and which generates vibrations during operation. In the case of a linear resonant actuator, the mass is usually magnetically accelerated on one axis and thus emits pulses. The size of the vibration device used can be defined by the pulses that are desired to be felt at the driver's foot and by the requirements of the customer. The exact mounting position can be centered or not centered. The vibration device can output vibration signals to the driver as tactile feedback during braking and acceleration, without the need for this to be repeated.

[0012] In a further advantageous embodiment of the pedal assembly, the common retaining element can be fastened in a vibration-decoupled manner to a partition wall between the engine compartment and the vehicle interior or to the vehicle floor. By fastening the pedal assembly to the vehicle floor instead of to a partition wall where a conventional pedal assembly is arranged, the newly gained installation space can be used for other components.

[0013] In a further advantageous embodiment of the pedal assembly, the common retaining element can be designed as a retaining plate with a plurality of recesses and reinforcing beams. The retaining plate can be designed in a "honeycomb" manner and have recesses of different sizes and shapes. The weight can be reduced by these recesses. The retaining plate can be produced cost-effectively and in large quantities, for example as a plastic injection molding or as an extruded profile or as a die-casting.

[0014] In a particularly advantageous embodiment of the pedal assembly, the common feedback assembly can be arranged on one of the reinforcing beams, which connects the edges of the two receiving openings to one another. The feedback assembly can preferably be positioned in a central position between the two pedal assemblies, so that the two pedal units can receive tactile feedback of similar strength. However, an arrangement in a non-central position between the two pedal units is also conceivable.

[0015] In another advantageous embodiment of the pedal assembly, the common feedback assembly can pass through a through opening cut out in the reinforcing beam, which connects the edges of the two receiving openings to each other. In this case, the corresponding vibration motor can include two unbalanced parts or eccentric masses. The first unbalanced part or the first eccentric mass can be arranged on one side of the through opening, and the second unbalanced part or the second eccentric mass can be arranged on the opposite side of the through opening.

[0016] In another advantageous design of the pedal assembly, the two pedal units can each include a modular pedal head for receiving the operating force of the driver's foot. Here, the pedal head can include a pad carrier and a replaceable pedal pad, and can be connected to a housing cover that can be moved with a small stroke along the height direction of the corresponding pedal unit. The pedal head has a relatively fixed position and has only a small stroke in combination with the movable housing cover along the height direction of the corresponding pedal unit. The small stroke of the housing cover in the height direction of the pedal unit is preferably in the range of 1mm to 10mm. When the housing cover is arranged on a bending beam, this small stroke can even be less than the value of 1mm and reduced to a value in the micrometer range. An advantage of a pedal unit with a small stroke is that the corresponding pedal unit can be positioned in the vehicle lining, that is, positioned below the foot pad, except for the movable housing cover and the pedal head, so that only the pedal head is visible. The foot pad can then be positioned on a carrier element or a support provided by the manufacturer, which, for example, has a sound-absorbing element and / or a foam padding. This means that the cutout of the foot pad is only limited by the size of the movable cover. If the mat also has to take into account the larger contour of the pedal head, the cutout must also be larger, which has a negative impact on the overall appearance. The recess in the mat is reduced to the minimum necessary by the pedal head that can be subsequently installed, and this recess is almost completely covered by the subsequently installed pedal head. The mat cutout can also be designed to be smaller if the mat is located above a modified removable cover and only the cutout for installing the pedal head or the pad carrier or the size of the parts of the fixing assembly arranged on the removable cover remains.

[0017] In a further advantageous embodiment of the pedal assembly, the pedal pad can be removably connected in a form-fitting and / or force-transmitting manner to a pad carrier, which can be removably connected in a form-fitting and / or force-transmitting manner to a removable housing cover. Preferably, the pedal pad can have a supporting structure to better hold the driver's foot. Due to frequent use, the pedal pad is subject to wear. Sometimes, due to wear reasons or visual reasons (design), the vehicle owner wishes to replace the pedal pad with another permitted variant. Since replacing the pedal pad requires force, for example because the rubber lip must expand in order to remove the pedal pad from the pad carrier or to fix it to the pad carrier, it is advantageous to remove the pedal head from the removable housing cover beforehand. This means that all work on the pedal pad or the pad carrier can be carried out in the disassembled state without applying force to the removable housing cover or the sensor housing with the sensor assembly. Due to the modular construction of the pedal head and the detachable fixing of the pedal head to the movable housing cover, the pedal pad can be easily replaced after the pedal head is removed without damaging the movable cover or the sensor housing. The pad carrier can be connected to the movable housing cover in a form-fitting and / or force-transmitting manner. As an example, for example, by enabling the pad carrier to be connected to the movable housing cover via a locking connection and / or a plug connection without the aid of tools, it is possible to quickly assemble the pad carrier at the movable housing cover or quickly disassemble the pad carrier. Disassembly can be performed using at least one simple auxiliary tool in order to release the locking connection and / or the plug connection. This means that the form-fitting and / or force-transmitting connection can preferably be released using at least one simple auxiliary tool.

[0018] Furthermore, anti-error measures (Poka-Yoke-Maβnahme), i.e. geometric component measures, can be provided between the movable housing cover and the gasket carrier, which make it impossible for the gasket carrier to be incorrectly assembled on the movable housing cover, for example in such a way that the gasket carrier can only be assembled in the correct position on the movable housing cover.

[0019] In a further advantageous embodiment of the pedal assembly, the movable housing cover can be connected to the sensor housing in an axially movable manner. To this end, the movable housing cover can have a circumferential flange which covers the wall of the sensor housing or can be surrounded by the wall of the sensor housing. This enables the movable housing cover to perform an axial relative movement with respect to the sensor housing.

[0020] In another advantageous embodiment of the pedal assembly, at least one sensor assembly can be arranged in the sensor housing, which detects and evaluates the stroke movement of the movable housing cover. At least one external electrical interface can be arranged at the sensor housing, via which at least one sensor assembly can be contacted and / or supplied with energy. The at least one sensor assembly can be electrically connected to the vehicle controller via the at least one external electrical interface. The at least one sensor assembly can include a movable measured value provider and a sensor electronics component. The at least one sensor assembly can, for example, detect smaller stroke movements of the movable housing cover without contact. The sensor electronics component can currently be understood as a circuit or structural unit with at least one sensor element, which can detect and process or evaluate magnetic signals and / or inductive signals and / or capacitive signals of the measured value provider without contact. For contactless detection of smaller stroke movements, a Hall sensor based on the magnetic principle can preferably be used. In addition or alternatively, a force sensor can also be used to detect the stroke movement, which is connected to the movable housing cover via a return spring. Here, the variable spring force can be converted into a voltage change in a sensor element constructed as a strain gauge, for example, which can then be amplified and evaluated. Of course, other suitable measuring methods known in the prior art, such as optical measuring methods, inductive or measuring methods, capacitive measuring methods, can also be used to detect and evaluate the smaller stroke movement of the movable housing cover. The sensor electronics can have a circuit board and at least one electrical or electronic component arranged on the circuit board. The at least one component can, for example, be a so-called ASIC component or a microcontroller, which can contain multiple functions for detecting and evaluating sensor signals. However, the at least one component can also be constructed as an integrated circuit or a discrete structural unit. In order to evaluate and / or further process the detected signal, a software module, for example, present on a microcontroller can also be used. It is also advantageous to have a computer program product with a program code, which is stored on a machine-readable carrier such as a semiconductor memory, a hard disk memory or an optical memory, and is used to perform the evaluation when executing the program. In addition, the evaluation of the sensor signal can also be carried out completely or at least partially in a vehicle controller electrically connected to the at least one sensor component.

[0023] Figure 2 Shows Figure 1 A schematic perspective side view of a portion of a vehicle footwell is shown.

[0024] Figure 3 Shows Figure 1 and Figure 2 A schematic perspective top view of a pedal assembly for a vehicle according to the present invention is shown.

[0025] Figure 4 Shows Figures 1 to 3 The illustrated embodiment is a schematic perspective view of a first pedal unit of a pedal assembly for a vehicle according to the present invention, which is configured as an accelerator pedal. DETAILED DESCRIPTION

[0026] like Figures 1 to 4 As shown, the illustrated embodiment of the pedal assembly 1 for a vehicle according to the invention comprises two pedal units 10, through which a vehicle function can be triggered respectively, and a common holding element 5, the holding element having two receiving openings 5.1. The two pedal units 10 are respectively inserted and held in corresponding receiving openings 5.1 of the common holding element 5. In this case, a common feedback component 26 is arranged between the two receiving openings 5.1 of the common holding element 5 or is integrated into the common holding element 5, and the common feedback component generates a predeterminable tactile feedback and outputs the tactile feedback to the driver's foot via the common holding element 5 and the two pedal units 10.

[0027] like Figures 1 to 3 As further shown, the pedal assembly 1 shown comprises a first pedal unit 10 configured as an accelerator pedal 5B for performing an acceleration function, which is arranged on the right side of the retaining element 5 in the figure, and a second pedal unit 10B configured as a brake pedal 5A for performing a braking function, which is arranged on the left side of the retaining element 5 in the figure. In this case, the common retaining element 5 in the illustrated embodiment is fixed to the partition wall 7 between the engine compartment and the vehicle interior in a vibration-decoupled manner. In an alternative, not shown, embodiment of the pedal assembly 1, the common retaining element 5 is fixed to the vehicle floor.

[0028] For the first pedal unit 10 configured as an accelerator pedal 10A, a tactile feedback signal is generated by the feedback component 26, for example, in order to signal the driver that his intention to accelerate and downshift has been recognized. For this purpose, the corresponding drive controller (not shown) triggers the feedback component 26 by a corresponding trigger signal. For the second pedal unit 10 configured as a brake pedal 10B, a tactile feedback signal is generated by the feedback component 26, for example, in order to signal the driver that the adjustment of the anti-lock braking system (ABS) is currently in progress. For this purpose, the corresponding brake controller (not shown) triggers the feedback component 26 by a corresponding trigger signal. The corresponding trigger signal can influence the generated tactile feedback signal in terms of signal form and / or signal duration and / or intensity. These trigger signals can be predetermined and adjusted by the vehicle manufacturer and / or the driver, for example. Of course, the feedback component 26 can also generate and output tactile feedback signals in other driving situations. For example, dangerous situations and / or fatigue can be displayed to the driver, and tips on how to save fuel can be given.

[0029] As especially Figure 2 and Figure 3 As further shown, the common retaining element 5 in the illustrated embodiment is designed as a "honeycomb-like" retaining plate 5A with a plurality of recesses and reinforcing beams 5.2. Figure 3 As further shown, the common feedback component 26 is arranged on one of the reinforcement beams 5.2, which connect the edges of the two receiving openings 5.1 to each other. Here, the common feedback component 26 in the illustrated embodiment passes through a through opening, which is not described in detail, and is introduced centrally into the reinforcement beam 5.2. The common feedback component 26 includes a vibration device 28, which in the illustrated embodiment is constructed as a vibration motor 28A having two unbalanced parts 28.1, i.e., eccentric masses, and generates a vibration signal with an adjustable frequency and / or adjustable intensity, and outputs the vibration signal to the driver's feet via the common retaining element 5 and the two pedal units 10. As shown Figure 3 As further shown, the first unbalanced part 28.1 or the first eccentric mass is arranged on one side of the through-opening, and the second unbalanced part 28.1 or the second eccentric mass is arranged on the opposite side of the through-opening. The size of the vibration device 28 used can be determined by the impulses that are desired to be felt on the driver's foot and the requirements of the customer.

[0030] In an alternative, not shown, embodiment of the pedal assembly 1, the vibration device 28 is designed as a linear resonant actuator. In a linear resonant actuator, a mass is usually magnetically accelerated in one axis and thus emits pulses.

[0031] like Figures 1 to 4As further shown, the two pedal units 10 each include a modularly constructed pedal head 20 for receiving the operating force of the driver's foot. The pedal head 20 includes a pad carrier 22 and a replaceable pedal pad 24, and is connected to the housing cover 12, which can be moved with a small stroke along the height direction z of the corresponding pedal unit 10. The pedal pad 24 is detachably and form-fittingly and / or force-transmittingly connected to the pad carrier 22, which is detachably and form-fittingly and / or force-transmittingly connected to the movable housing cover 12. Here, the pedal pad 24 of the pedal head 20 in the illustrated embodiment has a curved deep-drawn shell 24.1 made of stainless steel, which is combined with a curved rubber component 24.2, so that a tubercle-shaped support structure 24.3 protruding from the deep-drawn shell 24.1 is formed on the upper side of the deep-drawn shell 24.1. The support structure 24.3 can prevent the driver's foot from slipping or at least make it more difficult to slip. The cushion carrier 22 is plugged onto the movable housing cover 12 and is fixed to the movable housing cover 12 by means of fixing or latching elements (not shown and described in detail).

[0032] As especially Figure 4 As further shown, the movable housing cover 12 in the illustrated embodiment is constructed in a cap-shaped manner with a cylindrical spring receiving portion, not shown in detail, on which a gasket carrier 22 is inserted. The movable housing cover 12 has a circular shape with a circumferential flange 12.1, which covers the wall of the sensor housing 16. Alternatively, the circumferential flange 12.1 of the housing cover 12 can be surrounded by the wall of the sensor housing 16. This enables the movable housing cover 12 to perform axial relative movement relative to the sensor housing 16. The cylindrical spring receiving portion is closed at one end by a cover, not shown in detail, and has a receiving opening for a return spring, not shown in detail, at the other end. Here, the cover of the spring receiving portion faces the pedal head 20 with the gasket carrier 22, and the receiving opening faces the sensor housing 16, so that the return spring, not shown in detail, is arranged between the cover of the spring receiving portion and the bottom of the sensor housing, not shown in detail. The gasket carrier 22 has a recess, not described in detail, which at least partially accommodates the cover of the cylindrical spring receiving portion or the cylindrical spring receiving portion. As Figures 2 to 4 As further shown, the bellows-shaped circumferential seal 14 covers the movable housing cover 12 and the sensor housing 16 in a fluid-tight manner in the overlapping region. Figure 4 A portion of the seal 14 is removed.

[0033] like Figure 1 and Figure 2As further shown, the remaining parts of the two pedal units 10, except for the removable cover 12 and the pedal head 20, are arranged below the foot mat 3, so that only the pedal head 20 is visible. The foot mat 3 is positioned on a support, which is not shown in detail for the sake of clarity and which is in turn applied to the holding element 5, which is designed as a carrier plate 5A. Figures 1 to 4 As further shown, the pedal unit 10 of the pedal assembly 1 shown no longer has a rod for the pedal head 20. This not only improves the appearance, but also improves the collision safety. Figure 1 and Figure 2 As further shown, the cutout of the mat 3 is limited only by the size of the fastening elements which fasten the mat carrier 22 to the movable housing cover 12 .

[0034] A sensor assembly 17, shown in dashed lines, is arranged in the sensor housing 9 and comprises at least one sensor element and corresponding sensor electronics for detecting and evaluating relatively small travel movements in the range of 1 mm to 10 mm of the movable housing cover 12. When the housing cover 12 is arranged on a bending beam, this relatively small travel can even be reduced to values ​​less than 1 mm and in the micrometer range.

[0035] like Figure 2 and Figure 4 As further shown, an external electrical interface 19 is arranged on the lower side of the sensor housing 16, via which the pedal unit 10 can be electrically connected to a corresponding controller. At least one sensor component 17 arranged in the sensor housing 16 is contacted and / or supplied with energy via the external electrical interface 19. Here, the first pedal unit 10 configured as an accelerator pedal 10A is electrically connected to a drive controller not shown in detail, and the second pedal unit 10 configured as a brake pedal 10B is electrically connected to a brake controller not shown in detail.
