- the third marker strip 420 is substantially perpendicular to the two marker strips 128, 130, resulting in an H-shaped arrangement.
- the three marking strips 128, 130, 420 each have a plurality of differently long spacer lines 422, which are each arranged between two markings of each marking strip at a uniform distance from each other.
- spacer lines 422 are each arranged between two markings of each marking strip at a uniform distance from each other.
- four spacing lines 422 each are arranged between two markings, with the exception of the two center position markings 410, 418, between which only three spacing lines 422 are present.
- the spacing lines 422 are substantially transverse to a longitudinal axis of the marking strip to which they each belong.
- a respective length of the spacer lines 422 on the first marker strip 128 corresponds to a respective distance of these spacer lines to the first mid-position marker 410 and a respective length of the spacer lines 422 on the second marker strip 130 a respective distance of these spacer lines to the second mid-position marker 418.
- Distance lines 422 of the two marker strips 128, 130 starting from a respective mid-position marker in both directions increasingly longer.
- the spacer lines 422 of the third marker strip 420 become progressively longer from the first mid-position marker 410.
- the marks and spacing lines of the three marker strips 128, 130, 420 may be detected at a detection location 424 where the sensor electronics on the printed circuit board face the marking surface 126.
- the detection point 424 corresponds, for example, to the detection range described with reference to FIG.
- the marker 16 is positioned in the guide device such that the first mid-position marker 410 is located at the detection location 424.
- the first middle position marking 410 is located in the beam path of a light beam emitted by the sensor electronics for scanning the marking surface 126.
- the detection device 500 is, for example, sensor electronics, as described with reference to FIGS. 1 to 4.
- the detection device 500 comprises a light source 502 for emitting a light beam 504, here an LED, an LED lens 506 for directing the light beam 504 to the detection point 424 on the marking surface 126 and a sensor lens 508 arranged opposite the marking surface 126 for steering one at the detection point 424 reflected light beam into a sensor 510, which is designed to use the reflected light beam to generate a motion signal 512 representing a movement of the marking surface 126 relative to the detection point 424 and to send it to an evaluation device 514.
- the evaluation device 514 is shown here schematically next to the sensor 510.
- the evaluation device 514 can be implemented as a separate unit from the detection device 500 or as a component of the detection device 500, for example the sensor 510.
- the evaluation device 514 is designed to determine a position of the selector lever in the switching device using the movement signal 512.
- the detection device 500 is a sensor of a computer mouse, wherein the marking surface 126 acts as a kind of mouse pad.
- the light source 502 is either one LED or a laser diode.
- the light reflected from the marker surface 126 is collimated by the sensor lens 508 and directed into a miniature camera 51 6 of the sensor 510.
- the mini-camera 516 is designed to send image information as movement signal 512 to the evaluation device 514, such as a digital signal processor (DSP), which receives the image information in the form of a gray scale image.
- DSP digital signal processor
- the evaluation device 514 converts the image information into speeds and calculates, from the velocities, motion data in the form of ⁇ and Ay values, which represent a distance traveled by the marking element along at least one detected marking strip. Based on this distance, a shift position of the selector lever can now be determined.
- the miniature camera 51 6 has a resolution of 1 6 ⁇ 16 to 30 ⁇ 30 pixels.
- the sensor 510 can record and evaluate on average, for example, 1500 frames per second.
- FIG. 6 shows a flow chart of a method 600 for determining a selector lever position in a shift device according to an embodiment of the present invention.
- the method may, for example, be carried out using a switching device as described with reference to FIGS. 1 to 5.
- the marking element is guided past the detection point in a method step 602 by means of the guide device. More specifically, in step 602, the marker is passed along the first marker strip at the detection location when the selector lever is moved along a first shift gate of the switching device represented by the first marker strip, and past the detection mark along the second marker strip as the selector lever moves along one the second marker strip represented second shift gate of the switching device is moved.
- a motion signal is provided by means of the detection device, which represents a movement of the first marker strip or a movement of the second marker strip or a movement of both the first and the second marker strip relative to the detection point.
- the motion signal can be evaluated to a position of the selector lever in the first shift gate or to determine the second shift gate, for example by means of an evaluation device described above with reference to FIG. 5.
- an exemplary embodiment comprises a "and / or" link between a first feature and a second feature
- this can be read so that the embodiment according to one embodiment, both the first feature and the second feature and according to another embodiment, either only the first Feature or only the second feature.
