TECHNICAL FIELD

The present disclosure is related to a selector lever resetting device for a vehicle transmission, a process for the operation of such selector lever resetting device, and a corresponding device as well as to a corresponding computer program product.

BACKGROUND

The increasing electronification of vehicle systems has also initiated a change in technology in the area of transmission control. The replacement of the mechanical transmission actuation is referred to as shift-by-wire. In this, the mechanical connection between the gear shifter and transmission can be replaced by an electric or electronic interface. The implementation of the shifting operation in the gearbox is done, for example, hydraulically or electrically.

To do this, a control element can be equipped with a sensor system for detecting the driver wishes, which can be passed on to the gear box via a corresponding interface.

BRIEF SUMMARY

Against this background, the present disclosure provides a selector lever resetting device for a vehicle transmission, a method and a device for the operation of such selector lever resetting device as well as finally a corresponding computer program product in accordance with the principal claims. Favorable arrangements are resulting from the subsidiary claims and the following description.

The present disclosure provides a selector lever resetting device for a vehicle transmission, in which the selector lever resetting device has the following characteristics:a selector lever to select a gear position of the vehicle transmission; anda lever guide equipment that has at least one sliding element and a locking slide, where the sliding element is arranged as movable in the lever guide equipment along a sliding axis and has a latching contour, in which the selector lever is mechanically coupled or is couple able with the sliding element, in order to be moved along the sliding axis between a latching position and an operating position, in which the locking slide is arranged as movable in the lever guide equipment along a slide axle different from the sliding axis at least between a latching position and a release position and has at least a latching element, in which the latching element is engaged with the latching contour, when the selector lever is in the operating position and the locking slide is in the rest position, and the latching element releases the latching contour, when the locking slide is in the release position.

Under a selector lever a lever arranged in a vehicle to operate the vehicle gearbox can be understood. The vehicle transmission can be executed as an electronically selectable gear box, also called as shift-by-wire transmission. Here, a control signal can be deployed to select a gear position of the vehicle transmission by actuating the selector lever. Under a gear position a transmission level or a mode of operation of the vehicle gearbox can be understood. Under a lever guide equipment the equipment can be understood, which is designed to enable a controlled movement of the selector lever between the defined lever positions. Under a sliding element a sliding plate or a sliding frame can be understood. Under a latching contour an elevation formed on the sliding element, a recess in the slide element or a hook-shaped element can be understood. Under a locking slide a sliding carrier element with a latching element can be understood. Under a latching element a component can be understood, which is formed to intervene in the latching contour that a movement of the selector lever is blocked along the sliding axis. For example, in case of the latching element it can be about a nose-shaped or hook-shaped element, which is formed to glide through an elevation of the latching contour and to wedge it with the latching contour or to get hooked in a recess of the latching contour.

The present approach is based on the recognition that a selector lever for a vehicle gearbox can be fixed by means of a latching mechanism in a predefined lever position and can be moved back when releasing the latching mechanism into a starting position. The latching mechanism can be released advantageously with very minimal effort, by, for example, moving the two interlocking latching elements against each other. Thus, it is possible to reduce an actuator force required to reset the selector lever in the original position when compared to conventional solutions. The actuator force can be reduced to a minimum, if a preload force acts on the selector lever in accordance with one embodiment described below, so that the selector lever is moved back by the preload force in the original position when releasing the latching mechanism. This can reduce the production cost of a selector lever resetting device. In addition, an acoustic of the selector lever resetting device can be improved as a result.

In a mechanical operating of the gearshift stick, for example, of a cable-controlled gearshift, the selector lever position always matches with the gear position because of the mechanical coupling such that the gear positions are stable; the selector lever positions are also stable.

An electric gear shift, also called as shift-by-wire or E-gear shift, may have no mechanical coupling between selector lever and gear. This can cause problems in operating the gearshift stick with the stable positions of selector lever. For example, under certain conditions and in the event of a fault it may lead to, that the selector lever position no longer aligns with the gear position, so that the driver may receive incorrect information in some circumstances. To prevent this, the selector lever of the gear position can be repositioned.

Using a selector lever resetting device pursuant to the approach presented here the selector lever of an actual gear position can be repositioned efficiently, so that it is ensured that the position of the selector lever aligns with the actual gear position. For example, the selector lever resetting device can be formed to move the selector lever to its activity in a non-critical position without having required the strong engines or large transmissions. Thus, an electronic shifting of the gears can be realized, which has similar stable selector lever positions such as a mechanical gear shifter despite missing mechanical coupling between gear box and selector lever.

In accordance with the present disclosure, an embodiment of the selector lever resetting device can be provided with at least a spring element that is formed to push the latching element against the latching contour. By this, a reliable locking of the latching contour is ensured with the latching element.

In accordance with an another embodiment the selector lever resetting device can be provided with a drive unit, which is formed to move the lock slide at least between the latching position and the position of the release. Under a drive unit, for example, an electric, pneumatic, or hydraulic motor or an electromagnet can be understood. The locking slide can be moved quickly and in controlled manner by means of the drive unit. By the fact that only frictional resistance will be overcome when moving the lock slide, the drive unit can be run very compact and cost-effectively.

The drive unit can advantageously be coupled with a step-up gear unit. In particular, the step-up gear unit can be formed to transmit a rotary motion generated by the drive unit into a linear movement of the locking slide. By means of the step-up gear unit, an efficient power transfer can be realized from the drive unit to the locking slide. Thus, the step-up gear unit enables the use of less expensive engines in particular by rotating motors as a drive unit.

The selector lever resetting device can have a gear shifting gate, which has at least a first recess associated with the latching position and a second recess associated with the operating position, where the first recess and the second recess are connected to each other through an inclined exchange area. Here, an end range of selector lever can be arranged in the gear shifting gate as movable at least between the first recess and the second recess. Under a gear shifting gate a shell-like device to guide the end range of the selector lever can be understood. For example, the gear shifting gate can have a base plate, in which the two recesses are formed. The recesses can be implemented as shift gates. Under an inclined surface of the exchange a bevel between the recesses can be understood. For example, the exchange area can be designed as a diagonal groove between the first and the second recess. By means of the gear shifting gate the selector lever can be moved comfortably, i.e. with low resistance along a predetermined path of lever. With this, it is also ensured that a lever position aligns with the gear position.

In accordance with a further embodiment, the selector lever resetting device can be realized with a preload device, which is formed to preload the selector lever with a preload force, wherein the selector lever is formed to be moved in the release position by the preload force from the operating position back to the latching position. Under a preload device a device can be understood, which is formed, to impinge the selector lever by means of a suitable preload means, such as a spring element, with a preload force. Such preload device has the advantage that the selector lever can be reset only through the action of the preload force, i.e. without the use of an additional actuator, in the latching position.

In order to realize an efficient selector lever resetting device with a possible compact design, the selector lever may include a lever recess. The preload device may comprise a locking body slidably arranged or arrangeable in the lever recess and at least one preload element for the preload of the locking body. An end portion of the locking body can be arranged slidably within the gear shifting gate at least between the first recess and the second recess. In particular, in this case the locking body can be preloaded in the operating position with a larger preload force than in the latching position. Under a locking body, an elongated, cylindrical body can be understood. Under a preload element a spring can be understood. For example, the spring can be tensioned in the lever recess between the locking body and the selector lever to preload the locking body. The end portion of the locking body can have one rounding corresponding to a shape of the first and the second recess. By the fact that the locking body may be preloaded in the actuating position with a larger preload force than in the latching position, it is ensured that the selector lever returns to the latching position reliably and with very little effort.

The first recess as automatic lane for the automatic shifting of the vehicle transmission and the second recess as a manual lane for the manual shifting of the vehicle transmission can be designed in accordance with an another embodiment. In particular the latching position can correspond to a parking position of the vehicle transmission. Under a parking position, also called as auto-P position, a position of the vehicle transmission can be understood, in which the vehicle transmission is blocked. Through this embodiment it is guaranteed that the selector lever automatically returns from the manual lane in the parking position in case of activating the parking position.

The locking slide, also called a locking element, can also have at least one blocking element and can be formed to be moved along the slide axle in a blocking position. Here, the blocking element in the blocking position can prevent any movement of the selector lever from the latching position to the operating position. Under a blocking element an element of the locking slide can be understood, which blocks a way of the selector lever in the blocking position. For example, the locking slide can be executed with a lug or a pin as a block element. By means of the blocking element, it can be prevented that the selector lever is reset accidentally in the rest position by a driver of the vehicle.

The selector lever with the sliding element can be coupled with very low production efforts and costs, if the selector lever is carried out by a recess of the sliding element.

The lever guide device can also have another slide element, where the further slide element is arranged along other sliding axis different from the sliding axis in movable manner in the lever guide device and is designed to allow a movement of the selector lever between a majority of predefined lever positions along the other sliding axis. In particular, in this case the sliding element and/or the locking slide can be arranged as moveable to the other sliding element. The other sliding axis and the slide axle can run especially parallel to each other. This form of execution allows a controlled operation of the selector lever in several directions. At the same time you can run the lever guide device with a most possible compact design. Thus, the selector lever can be used for the control of several different functions.

The approach presented here also creates a process to operate a selector lever resetting device in accordance with one of the previously described embodiments, whereby the procedure includes the following steps:engagement of the latching contour with the latching element due to a movement of the selector lever from the latching position to the actuating position along a sliding axis; andrelease of the latching contour due to a movement of the locking slide from the latching position to the release position along a slide axle different from the sliding axis.

Finally, the present approach creates a device that is formed to perform or to control all steps of a procedure in accordance with one of the embodiments described herein.

An electrical device can be understood under a device in this case, which processes the sensor signals and gives output as a function of control and/or data signals. The control unit can have an interface, which can be formed by hardware and/or software. In case of a hardware formation, the interfaces can be, for example, a part of a so called system ASIC, which includes a wide range of functions of the control unit. However, it is also possible that the interfaces are of their own, integrated circuits or at least partially composed of discrete components. In case of a software formation the interfaces can be the software modules, which are available, for example, on a microcontroller in addition to other software modules.

It may also be advantageous to provide a computer program product with program code that can be stored on a machine-readable disk such as a semiconductor memory, on a hard drive memory or on an optical memory, and is used to perform the procedure in accordance with one of the above-described embodiments, when the program is run on a computer or device.

DETAILED DESCRIPTION

In the following description of preferred embodiments of the present disclosure, the same or similar reference signs are used for the elements shown in the various figures and similar-looking elements, in which a repeated description of these elements is removed.

FIG. 1shows a schematic cross section presentation of a selector lever resetting device100in accordance with one embodiment of the present disclosure. The selector lever resetting device100includes a selector lever105to select a gear position of vehicle gearing (not shown here) and a lever guide device110. The lever guide device110includes a sliding element115and a locking slide120. The sliding element115is arranged movable along a sliding axis125in lever effect device110. The sliding element115is plate-like shaped and has a recess, through which the selector lever105is carried out to mechanically couple the selector lever105with the sliding element115. The selector lever105is formed to be moved using the sliding element115between a latching position130and an operating position135along the sliding axis125. As an example, the selector lever105is arranged in the latching position130at right angles to the sliding element115and arranged in the operating position135at an acute angle to the sliding element115. InFIG. 1the selector lever105is shown in the operating position135.

The locking slide120is arranged according to this embodiment in a marginal area of the lever guide device110along the slide axle140deviating from the sliding axis125movable between a latching position and a release position on the sliding element115. InFIG. 1the slide axle140and the sliding axis125are exemplarily running perpendicular to each other, where the slide axle140runs perpendicular to a consideration level and thus is presented as a point. The sliding element115is formed to move the selector lever105in the operating position135so in the direction of the locking slide120, that a marginal area of the sliding element115is covered by the locking slide120.

The slide element115includes a locking contour145, also called as rastering or rastering contour, which is formed as an elevation in the marginal area of the sliding element115according to this embodiment. The locking slide120comprises a latching element150, which is latched in the latching position of the locking slide120that is shown inFIG. 1with the latching contour145. The latching element150can also be referred to as a rastering element.

According to this embodiment the latching element150is performed as a latch nose, which is formed to be pressed while moving the sliding element115in the direction of the lock slide120, i.e. When you move the selector lever105in the operating position135, through the elevation of the latching contour145, so that the selector lever105is fixed in the operating position135.

InFIG. 1the selector lever resetting device100is shown with an optional additional sliding element155, where the other sliding element155is arranged along another sliding axis moveable in lever guide device110. According to this embodiment, another sliding axis matches with the slide axle140, so that the sliding element115and the other sliding element155are perpendicularly moveable to each other. Also the sliding element115, as shown inFIG. 1, can be arranged movable in the other sliding element155. The other sliding element155thus fulfills the functions of a framework to guide the sliding element115along the sliding axis125. The other sliding element155can also be referred as longitudinal slide and the sliding element115also as cross section slide accordingly. The other slide element155can be arranged in turn moveable in a direction of a track or latching device not shown here, which can be some part of a casing of selector lever resetting device100. Thus, the selector lever105is formed, to155to be moved along two sliding axis125,140by means of the sliding elements115. For example, the selector lever105is movable along the other sliding axis140between majorities of the predefined lever position.

The locking slide120can be arranged adjacent to an edge of the other slide element155running parallel to the other sliding axis140or to the slide axle140. The edge can serve as a guide track to guide the locking slide120between the latching position and the position of the release.

The selector lever resetting device100additionally includes a gear shifter160. The gear shifter160is designed as a shallow element with a scene recess165. A floor space of the scene recess165has a first recess170and a second recess175. First recess170is designed, for example, as automatic lane for the automatic shifting of the vehicle transmission and the second recess175as a manual lane for the manual shifting of the vehicle transmission. The recesses170,175are thus forming a rastering for the selector lever105. The manual lane can also be called tip lane. The recesses170,175are interconnected via an exchange lane180, in which the exchange lane180acts as an exchange area to change a position of lever between the first recess170and the second recess175.

As an example, the first recess170is run with a depth greater than the second recess175. The exchange lane180thus has a tendency.

The lever end185of the selector lever105is arranged movable between the first recess170and the second recess175in the gear shifter160. The lever end185is arranged and formed in the second recess175in the operating position135to be moved in the first recess170when you move the selector lever105in the latching position130via the exchange lane180. For example, the latching position130matches with a parking position of the vehicle transmission.

According to this embodiment, the selector lever resetting device100is realized with an optional preload device190. The preload device190includes an elongate locking body195and a preload element196for the preload of the latching body195. The preload element196is implemented by way of example as a helical spring. The selector lever105is formed in the area of the lever end185with a lever recess198, in which the latching body195is arranged moveable in the lever recess198. By way of example, the latching body195inFIG. 1is moveable along a longitudinal axle of the selector lever105.

According to this embodiment the latching body195, which can be described as rastering element, is carried through by the preload element196, where the preload element196is clamped in the selector lever105, that an end portion of the latching body195is pressed by a preload force of the preload element196in the gear shifter160. The end portion of the latching body195is jutting out into this pretensioned state of the selector lever105from the lever recess198. The end portion of the latching body195thus forms the lever end185as moveable between the recess170and175. The latching body195is formed to press the selector lever105in the release position of the locking slide120not shown here by the preload force of the actuating position135on a slope of the exchange lane180and back to its latching position130. By the fact that the second recess175has a lower depth than the first recess of170, the prestressing of the header element196in the operating position135, in which the lever end185is arranged in the second recess175, is greater than in the latching position130, in which the lever end185is arranged in the first recess170.

In contrast toFIG. 1the lever end of selector lever105is arranged in the first recess, which is realized as automatic lane. The selector lever105is formed in and out to be moved between various lever settings in the automatic lane. As already described on the basis ofFIG. 1, the second recess175is implemented as a manual lane accordingly.

In addition the locking slide120has a block element200. The block element200is implemented by way of example through a flat projection of a bottom plate of the locking slide120, which extends the projection on a base of the locking slide120. The blocking member200extends adjacent to a surface of the sliding element115and parallel to a main extension level of sliding element115. Alternatively, the blocking member200may be formed as a pin or as another element with an appropriate geometrical shape.

The locking slide120is arranged in theFIGS. 2ato 2din a blocking position in contrast toFIG. 1, in which the selector lever105is blocked by the block element (or locking element)200, that the selector lever105is locked up in the automatic gate, i.e. can be moved only along the automatic gate.

The selector lever resetting device100shown inFIGS. 2ato 2dis also equipped with a drive unit205, which is exemplified as an electric motor and is coupled mechanically with the locking slide120to the locking slide120along the slide axle140between the locking position to move the release position and here shown blocking position. In order to realize a most compact design of the selector lever resetting device100, the drive unit205can be arranged on the blocking slide120.

FIG. 3ddisplays the selector lever105in a first manual shift position, also called as Plus position, in which the selector lever105is arranged in a first end of the manual gate175. For example, the vehicle transmission is designed to be switched when moving the selector lever105in the plus position in a higher gear.

FIG. 3eshows the selector lever105of a second manual shift position, also called as minus position in which the selector lever105is arranged in a second end of the manual gate175. For example, the vehicle transmission is designed to be switched while moving the select lever of105in the minus position in a lower gear.

In particular, a cutout view of the selector lever resetting device100shown inFIG. 3ais represented InFIG. 4. The lock slide120is shown with a guide channel400for guiding the locking element150. As an example, the guide channel400runs perpendicular to the sliding element115. There is a spring element405in the Guide Channel400. The spring element405is connected between an end opposite the locking element150channel end of the guide channel400and the locking element150is clamped such that the locking member150is pressed against the edge region of the sliding element115, in which the latching contour145is designed as an elevation. Thus, a slip resistant locking of the locking element150is made possible with the latching contour145in here not shown latching position of the locking slide.

The selector lever resetting device100is realized also inFIG. 4with a transmission gear410, which extends as an example along the slide axle140in the locking slide120. Here, a shaft of the drive unit205is rotationally fixed to the transmission gear410, respectively. The transmission gear410is formed, for example as a spindle and serves to transmit a rotation of the shaft of the drive unit205in a linear movement of the locking slide120along the sliding axis140.

Due to a movement of the locking slide of the locking position in the release position along a sliding axis different from the slide axle, the latching contour is now released in step1010.

According to one embodiment, a lever motion is generated by means of two latching contours and an actuator, for instance by means of an electric motor, but also by means of other actuators such as linear actuators, solenoids, piezo elements or muscle wires.

FIG. 11shows a block diagram of a device1100to perform a procedure in accordance with one embodiment of the present disclosure. The device100includes a reverse latch unit1105to the locking of the latching contour with the locking element due to a movement of the select lever from the initial position to the actuating position along a sliding axis, as well as a release unit1110to share the latching contour due to a movement of the locking slide from the locking position to the release position along a sliding axis different from the slide axle.

The embodiments described and shown in the FIGS. are chosen only by way of example. Different examples of execution can be combined fully or in relation to individual characteristics. Also, an embodiment can be supplemented by features of a further embodiment.

In addition, this procedure can be reviewed and executed in a language other than in the described order. Further, when an embodiment is described with a first feature and a second feature, it may so be read that the embodiment may have both the first feature and the second feature and in accordance with another embodiment has only one of the first feature and the second feature.
