Description

The present invention relates to a device and a method for inputting and displaying values as well as a corresponding system. In particular, the invention also relates to a system for testing a device under test. A device under test should in particular be understood as electronic devices to be tested.

State of the art

When testing electronic devices for fitness, specialized test devices are often used. For example, such test devices may generate input signals for the device under test and receive and evaluate thereon output signals of the device under test. Furthermore, test devices can use model calculations to determine a desired value which the output signal of the test object should ideally assume. For a complete test, it is advantageous to be able to quickly change an input signal or a plurality of input signals for the test object and / or the model calculation. The input signal or signals may in particular be setpoints.

For such test devices special display and control devices are often used, which can also be referred to as an operator computer, operator PC or, English, as an operating PC. Via a software executed by the display and control device, the test device can be controlled in real time and values output by the test device can be displayed in real time. Such a system of a test device and a display and control device is also referred to as a hardware-in-the-loop system, in short: HIL system. Such display and control devices, i. Devices for displaying and entering values are often made particularly compact, so that they are transportable and versatile. Thereby, the space on the device which is usable for displaying and inputting values is limited.

Conventionally, rotary control elements are used to set values, while pointer elements are used to display values. In the EP 0805340 B1 a conventional pointer element is described with a mounted on a rotatably mounted hub pointer vane.

Thus, there is a need for a device for displaying and inputting values by means of which values can be displayed and entered in a particularly space-saving manner, and by means of which the values to be entered can be input particularly quickly and precisely.

Disclosure of the invention

The present invention discloses a device having the features of claim 1, a system having the features of claim 6 and a method having the features of claim 9.

Accordingly, there is provided an apparatus for entering and displaying values, comprising: a scale of values; a first indicator device and a second indicator device, by means of which values can be indexed on the scale of values; wherein the first indicator means is adaptable by a user to index a first value to be entered on the scale of values; a controller adapted to determine the first value indexed by the first indicator means; an interface device, by means of which the determined first value can be transmitted to a further device and by means of which a second value generated by the further device based on the transmitted first value can be received; wherein the control and display means is adapted to automatically adjust the second indicator means based on the received second value for indexing the second value on the scale of values.

The value scale may in particular be a numerical value scale which has numerical values as values. However, value scales are also conceivable which have symbols or states as values, for example "too large", "too small", "permissible", "inadmissible", "unknown" or the like.

By indexing a value is to be understood in particular that the corresponding indicator means a value of the scale of values, in particular uniquely, for example, by pointing to the value, by lighting or backlighting the value, by visualizing the value, by orbiting the value or the like.

The first and second values preferably relate to the same size, in particular a physical quantity, for example a rotational speed of a shaft or of an engine or similar variables.

The further device may in particular be a test device, i. a device designed to test a device under test using the first value and / or to calculate a model value based on the first value. The further device may also be a regulating device or an actuator device.

Furthermore, the invention provides a system with a device according to the invention as well as with a further device which is designed to generate the second value based on a first value received from the interface device of the device and to transmit it to the interface device.

Further, the invention provides a method of entering and displaying values, comprising the steps of: adjusting a first indicator means by a user to index a first value on a scale of values; Determining the indexed first value; Generating a second value based on the determined first value; and automatically adjusting a second indicator means such that the second indicator means indexes the second value on the scale of values.

Advantages of the invention

The finding underlying the present invention is that one and the same scale of values can be used both for indexing a value to be entered and for indexing at least one value to be displayed. The invention thus provides a particularly space-saving possibility for simultaneously displaying the second and for entering the first value, in particular in real time. The user is enabled by the device according to the invention and the corresponding method to be able to change both a value to be entered on a single scale of values and to be able to read the result of these changes directly. Thus, a likelihood that a result of a change in the value to be inputted is overlooked by the user is reduced.

A multiplicity of values can be represented by a correspondingly large number of indicator devices, for example two, three, four or even more, without requiring additional space. Thus, the device can be made even more compact, or provide additional space-consuming functions, while maintaining the same size.

In particular, when the value to be entered, that is, the first value, and the value to be displayed, that is, the second value, are logically closely related, the invention provides a particularly intuitive operation of the device according to the invention. Even with small differences between the first and the second value, it can be visually easily recognized whether the values differ from each other and how strongly they do so.

Advantageous embodiments and further developments emerge from the dependent claims and from the description with reference to the figures.

According to an advantageous development of the device according to the invention, the first and second indicator means are designed such that both the first and second indicator means are recognizable to the user if both the first and second indicator means indicate the same value on the scale of values. Likewise, it is possible to proceed with further indicator devices, in particular if the indicator devices are displayed virtually on a screen device. Thus, both the first and the second value, possibly also other values, can be read out at the same time for the user at any time.

According to a further advantageous development, the device comprises a screen device, by means of which the value scale and / or the first and / or the second indicator device can be displayed. Thus, the value scale is flexibly adaptable, for example automatically to a connected test device and / or a test object to be tested.

According to a further advantageous development, the value scale is designed as a linear, an elliptical, an elliptical-segment-shaped, a circular or a circular-segment-shaped value scale, in particular in each case a numerical value scale. Thus, the values of the value scale are particularly space-saving and very clearly displayed.

According to a further advantageous development, the device comprises at least one digital display device which is designed to display the first value displayed by the first indicator device and / or the second value indexed by the second indicator device and / or any further values in numerical form. Thus, the indexed values are particularly fast and precise and at the same time space-saving readable.

According to a further advantageous development, the further device of the system according to the invention is designed to generate the second value based on the first value using a computer model stored in the further device.

According to a further advantageous development, the further device is a test device which is designed to generate the second value by transmitting the first value to a test object to be tested and one from the test object, in response to the transmitted first value, the value generated is determined as the second value.

According to a further advantageous development, the first and / or the second value, if appropriate also further values, an actual value, a desired value, an estimated value or a measured value are in each case related to one and the same variable. Thus, it is immediately and intuitively recognizable to a user that the values relate to the same value range and, for example, have the same limit values.

The device 10 includes a scale of values 16 and a first indicator device 21 and a second indicator means 22 , by means of which values on the scale of values 16 are indexable.

For example, the value scale 16 be formed as a linear, elliptical, ellipsenabschnittsförmige, circular or circular section-shaped, for example horseshoe-shaped, value scale. The indicator devices 21 . 22 may be formed or displayed as physical pointer flags or, preferably, as virtual pointer flags.

By means of a control device 14 the device 10 is the first value indexed by the first indicator means 51 determinable. The device 10 further comprises an interface device 18 by means of which the determined first value 51 to another device 60 can be transmitted and by means of which one of the other device 60 based on the transmitted first value 51 generated second value 52 is receivable. The control and display device 14 is designed to be the second indicator device 22 automatically based on the received second value 52 to index the second value 52 on the scale of values 16 adapt.

The device 10 and each of the alternatives or variants of the device described below 10 are each hardware or software or in a mixture of hardware and software feasible. For example, the first and second indicator means 21 . 22 physical pointer flags, wherein a position of the first indicator means 21 in terms of the scale of values 16 by the control device 14 is detected mechanically or electronically.

As in 1 further shown, the system according to the invention comprises 1 the device 10 and the other device 60 , The other device 60 may be designed to be the second value 52 based on the first value 51 using one in the further device 60 stored computational model or generate. Additionally or alternatively, wherein the further device 60 be designed to the second value 52 by generating the first value 51 to a test object to be tested 70 transmitted and one from the examinee 70 in response to the transmitted first value 51 generated value as a second value 52 or determined as a third value.

The further device can in particular be a test device 60 be. In the following, the further device will be explained as a test device 60 described. However, the further device can also be, for example, a regulating device or an actuator device, which receives the first value as the desired value for a predetermined size and generates an actual value for the same value as the second value and to the device 10 transmitted. For example, the further device may be a thermostat.

For the examinee 70 it may in particular be an electronic device, preferably an electronic device in, or for use in, a motor vehicle. For example, the device under test may be an electronic control unit (ECU) for a motor vehicle, in particular for its drive. The test device 60 For example, it can also have an analogue sensor system which is suitable for generating the second value 52 or a fourth value.

2 shows a schematic block diagram of a device 110 for inputting and displaying values according to yet another embodiment of the present invention.

The device 110 is a variant of the device 10 and also from the system 1 or a variant thereof. The device 110 also includes a screen device 112 , by means of which a value scale 116 and a first indicator device 121 and a second indicator means 122 can be graphically displayed.

3A to 3C show part of the through the screen device 112 illustrated value scale 116 , the first indicator device 121 and the second indicator means 122 in three different situations.

The scale of values 116 is according to 3A designed as a horseshoe-shaped number scale with exemplary values of minus six thousand to plus six thousand. The first indicator device 121 is as a bar 124 formed and illustrated, which, similar to a physical pointer flag, at a first end at a midpoint 115 the scale of values 116 is rotatably fixed while a second, unfixed end of the beam 124 Numerical values on the scale of values 116 indexed. Instead of a bar, the first indicator device 121 for example, also arrow-shaped, triangular, etc. may be formed.

The first indicator device 121 is rotatable by a user, so numerical values on the scale of values 116 by means of the second end of the beam 124 are indexable. Turning the bar 124 can be done for example by means of a pointing device, which with the device 110 is connectable. The pointing device can be, for example, a computer mouse, a trackball, a joystick or a touchscreen, which interact with the device 10 connected or in the device 10 can be integrated. For example, the screen device 112 be designed as a touch screen and thus act as a pointing device. A graphic pointer moved by the pointing device 150 For example, a mouse pointer may be controlled to change its appearance, such as from an arrow to a hand, when it is on a portion of the scale of values 116 or on the beam 124 is guided, see 3B ,

Click or press on the bar 124 by means of the pointer 150 the pointing device, for example by means of a computer mouse, moving the bar 124 to a first value to be entered 51 and releasing the bar 124 on the first value to be entered 51 (so-called "drag and drop" method) is this value on the scale of values 116 indexable. The value thus indicated is determined by the control device 114 automatically as the first value to be entered 51 certainly.

The scale 116 can continue at least one designated area 140 which can be activated to the first indicator means 121 accurate to a designated area for each 140 set predetermined value. Are the marked areas 140 For example, designed as mechanical push buttons or touch control surfaces, the activation can be done by pressing the designated area. In 3B a case is shown in which the marked area 140 graphically through the screen device 112 represented and by means of the pointer 150 are clickable. By clicking on a marked area 140 , in 3B for example, a designated area 140 , which is assigned a numerical value of minus three thousand, jumps the first indicator means 121 , as in 3C shown immediately to this value, while the second indicator device 122 , as the second value generated accordingly 52 indexed about minus two thousand three hundred and fifty. The pointer 150 may be configured to change its appearance, such as from an arrow to a hand, while over one of the marked areas 140 is positioned.

It can be provided that with the first indicator device 121 any values on the scale of values 116 are indexable. Alternatively it can be provided that only certain values on the value scale 116 indexable, for example, values for the candidate 70 permissible or harmless. The control device 114 can do this be formed, via the interface device 18 automatically information from the examinee 70 , for example about the further device, in particular test device 60 to obtain what values for the examinee 70 or the further device, in particular test device 60 , permissible or harmless, whereupon the indicator device 121 is displayed appropriately adjustable. A permissible range for the first indicator device 121 For example, it can be colored or backlit on the scale of values 116 being represented.

By the control device 114 becomes the definite first value 51 in a first, digital or analog, signal to the interface device 18 the device 110 forwarded by which the first signal automatically to one with the interface device 18 connected test device 60 is transmitted. At the test device 60 in particular, it may be a real-time computing device (RTPC). The test device 60 may be configured in a real time environment using the transmitted first signal and / or the transmitted first value 51 Generate and / or evaluate computational models. Based on this, the test device generates 60 a second value 52 , which by a second digital or analog signal to the interface device 18 is transferable. Instead of using, or in addition to, a computational model, the test device 60 also be designed to the first value 51 to a test object 70 to submit and a reaction of the examinee 70 to the first value 51 as the second value 52 and / or determine as a third value which one or more to the interface device 18 is or is communicable.

The to the interface device 18 transmitted second value 52 is sent to the controller 114 forwarded, which automatically the second indicator device 122 controls, the second value 52 on the scale of values 116 to index. The second indicator device 122 is designed as a virtual pointer flag so that it the bar 124 the first indicator device 121 is neither covered nor covered by this, if the first and the second indicator means 121 . 122 the same value on the scale of values 116 index. In other words, both the first and the second indicator device are always advantageous 121 . 122 readable, such as in the illustrated graphic plane further down indicator devices are shown wider than indicator devices located further up.

3D shows a fragmentary alternative, through the screen device 112 displayed display. This ad includes the value scale 116 , the first indicator device 121 and the second indicator means 122 , Furthermore, the display comprises a third indicator device 123 and first to third digital display devices 231 . 232 . 233 optionally also part of the device 110 could be.

The third indicator device 123 is configured to apply a third value to the interface device 18 was transmitted on the scale of values 116 to index. In particular, the third value may be based on the first value 51 from the test device 60 and / or the examinee 70 generated and to the interface device 18 be transmitted. For example, the second value may be 52 around one of the test device 60 model value and the third value is one of an ECU as a candidate 70 value for which both of the first value entered by the user 51 is a desired target value, input value or comparison value.

The first, second and third digital display devices 231 . 232 . 233 indicate in each case by means of digits that value which the first, second and third indicator means 121 . 122 . 123 according to the value scale 116 index. The first display device 231 may be configured to be user customizable by entering digits. This can be done for example by means of a keyboard, a keypad, etc., which in each case by the screen device 122 be shown or physically formed and with the device 110 can be connected. In 3D For example, a situation is illustrated in which the user exemplifies the value "3333" in the first digital display 231 . 232 . 233 entered. Thereupon was by the control device 114 the first indicator device 121 adjusted, the value "3333" on the scale of values 116 to index. According to the - exemplary - calculations or tests of the test device 60 show the second and third digital display devices as the second value 52 or the third value "3335".

Through the customizable first digital display device 231 is the first value 51 very precise input. By the second and the third digital display device 232 . 233 are the second value 52 and the third value can be read very precisely. Advantageously, the first, second and third indicator means 121 . 122 . 123 and the first, second and third digital display devices 231 . 232 . 233 formed in pairs of the same color, so that it is immediately obvious to the user, which indicator device and which digital display device refer to the same value. For example, the bar 124 the first indicator device 121 as well as a border 234 the first digital display device 231 blue, while an indicator needle of the second indicator device 122 as well as a border 235 The second digital display device 232 red and a pointer needle of the third indicator device 123 as well as a border 236 the third digital display device 233 are shown in green.
