Description

The present invention relates to a method for driving a touch-sensitive operating element for a vehicle.

Furthermore, the present invention relates to a touch-sensitive operating element for a vehicle with an optical and / or acoustic output unit for outputting an optically and / or acoustically perceptible feedback, wherein the operating element is designed to carry out the above method.

In addition, the present invention relates to a vehicle having a touch-sensitive control element and an optical and / or acoustic output unit for outputting an optically and / or acoustically perceptible feedback, wherein the vehicle is designed to carry out the above method.

Touch-sensitive controls are now being used more and more in various technical fields, e.g. in operator panels, touch-sensitive displays or as touchpads. An advantage of these touch-sensitive controls is that they are universally applicable, an operation can be detected electronically and various functions can be assigned. The touch-sensitive controls nowadays usually include capacitive controls. Mechanical switching elements are thus not required, whereby these controls are compact, inexpensive and low maintenance.

In order to make the operation of such touch-sensitive controls user-friendly, a haptic feedback is usually generated via the touch. The haptic feedback is generated by actuators or by a corresponding mechanism, which triggers the response noticeably after exceeding a force threshold during actuation. To guarantee this, additional hardware costs are incurred, which make the use of such touch-sensitive controls more expensive.

It is important in particular when used in a vehicle that the operating element can be easily triggered, preferably without direct eye contact is required. This is particularly important when multiple actuators are arranged together on such an operating element. However, without eye contact, it is difficult for a user to exactly locate his finger on the control element and which actuator he triggers.

Such a touch-sensitive operating element is for example from the US 2013/0201149 A1 known.

Based on the above-mentioned prior art, the invention is therefore based on the object to provide a method for controlling a touch-sensitive control element for a vehicle and a touch-sensitive control for a vehicle and a vehicle with a touch-sensitive control, wherein the touch-sensitive control is inexpensive to manufacture and a simple and reliable feedback on an operation of the control is done. In particular, it is desirable to enable the use of the touch-sensitive control element in a vehicle at low cost.

The object is achieved by the features of the independent claims. Advantageous embodiments of the invention are specified in the subclaims.

The invention thus provides a method for controlling a touch-sensitive operating element for a vehicle, comprising the steps of providing at least one actuating element to the touch-sensitive operating element, detecting a touch of the at least one actuating element, outputting an optically and / or acoustically perceptible feedback on the touch of the at least one Actuator, starting a touch timer with a predetermined period of time, outputting a visually and / or audible perceptible feedback on a continuous contact of the at least one actuating element, detecting a sequence of the touch timer, and triggering the touched operating element.

According to the invention, a touch-sensitive operating element for a vehicle with an optical and / or acoustic output unit for outputting a visually and / or acoustically perceptible feedback is also specified, wherein the operating element is designed to carry out the above method.

Further, according to the invention, a vehicle is provided with a touch-sensitive operating element and an optical and / or acoustic output unit for outputting a visually and / or acoustically perceptible feedback, wherein the vehicle is designed to carry out the above method.

The basic idea of the present invention is thus to provide an optical and / or acoustic feedback on the actuation of the at least one To generate actuating element. This concerns, on the one hand, an immediate output of a touch of an actuating element, as well as a corresponding output, which serves as feedback on the touch. Thus, an intuitive operation of the at least one actuating element can be ensured without the need for eye contact. As a result, driving safety is increased, especially in vehicles while driving. The driver no longer has to avert his eyes from the traffic or other, more important displays of the vehicle in order to trigger a desired function via the actuating element. Thus, the user can accurately estimate even where he is with his finger on the touch-sensitive control, even without direct eye contact, since there is a corresponding feedback. This is particularly important if a plurality of actuation elements are arranged on the touch-sensitive operating element, and the user wishes to trigger a function via one of the actuation elements. By the touch timer, the actuator is not triggered immediately to avoid erroneous entries.

In addition, the optical / acoustic feedback gives an indication of a status of the actuation, i. a duration of operation, thus ensuring intuitive operation. Thus, an actual input request for a residence time on corresponding actuators can be ensured and an accurate feedback on the actuation status.

Accordingly, it is possible to dispense with devices such as force sensors or push buttons which determine the actual input request.

In a vehicle which already has a corresponding optical and / or acoustic output device, the operating element can be designed without its own output device. The operating element can be connected via a corresponding interface to the output device of the vehicle in order to use the output device. This can be implemented, for example, in software in a control unit of the vehicle.

By realizing an optical and / or acoustic feedback via already existing output units, additional material costs can be saved during the production of the operating element.

According to the method, an actuating element can be operated, or several actuating elements can be actuated simultaneously. If possible, required visual and / or acoustic feedback can be provided in parallel or sequentially.

The touch-sensitive operating element is, for example, a capacitive operating element. The touch-sensitive operating element may additionally comprise a display device.

The actuating element may be a permanently installed actuating element which reacts in a touch-sensitive manner.

The start of the touch timer with a predetermined period of time includes a timer, at the end of which the actuator is triggered. Thus, if the touch-sensitive control is continuously pressed during the expiration of the touch timer, the actuator is triggered. The touch timer can in principle also be executed before or after other steps. The predetermined period of time may be in the range of a few seconds or less.

In an advantageous embodiment of the invention, the at least one actuating element is designed as a virtual input element, and the method comprises a step of assigning the at least one virtual input element to the touch-sensitive control element. The virtual input element can thus provide the actuating element by an assignment of the touch-sensitive control element or part of it to a function. So there is a logical assignment. This may be accompanied by a corresponding indication on the touch-sensitive control element when the touch-sensitive control element is designed for this purpose. In the case of a plurality of virtual input elements, correspondingly different regions of the touch-sensitive operating element are assigned to different functions.

A typical application would be for example a touch-sensitive display, on the display of a variety of functions via so-called icons are selectable. The icons would be the virtual input elements.

The assignment of the at least one virtual input element may be a quasi-static assignment, which is fixed for a vehicle. Alternatively, the at least one virtual input element can be assigned dynamically, for example, depending on a previous operation, different driving situations or operating states of the vehicle, or the like. The touch-sensitive control element thus provides a central function for detecting an operation. About the assignment of the at least one virtual input element is at least one area as defined virtual input element that can be operated.
In an advantageous embodiment of the invention, the method comprises an additional step of outputting an optically and / or acoustically perceptible feedback about the triggering of the at least one actuating element. Thus, there is a separate signal which provides the user with a confirmation of the actuation of the actuating element done. The optically and / or acoustically perceptible feedback can be made in accordance with the output of an optically and / or acoustically perceptible feedback on the touch of the at least one actuating element or the output of an optically and / or acoustically perceptible feedback via a continuous contact of the at least one actuating element. For example, feedback may be provided by a variety of audible tones, by playing different pitches for fixed functions, outputting symbol / function names, or issuing specified numbers.

In an advantageous embodiment of the invention, the step of outputting an optically and / or acoustically perceptible feedback via the touched actuating element comprises an indication of an information corresponding to the touched actuating element. The display of the information may be by the touch-sensitive control itself, i. by a display unit of the touch-sensitive control element, or via a display unit of the vehicle. The display unit may be embodied, for example, as a Head Up Display (HUD), cluster display in a region between a speedometer display and a tachometer, or as part of an infotainment system of the vehicle. The display may include, for example, displaying various symbol / function names or fixed numbers or fading in a feature icon.

In an advantageous embodiment of the invention, the step of outputting an optically and / or acoustically perceptible feedback via the touched actuating element comprises an announcement of an information corresponding to the touched actuating element. The announcement can be any announcement, for example a function name or a fixed number in spoken language. In principle, however, a simple announcement can also include a variation of acoustic tones or playing of different pitches for fixed functions.

In an advantageous embodiment of the invention, the step of outputting an optically and / or acoustically perceptible feedback via a continuous contact of the at least one actuating element comprises a variation of the output depending on a duration of the contact. It thus takes place from the start of the touch timer until its expiration an output that can be pointwise or continuously. A progress output for detecting an operation is provided. A duration of the touch can be detected, for example, via the touch timer. Changing the output tells the user that they are still touching the actuator. For example, depending on the type of output, how long the contact must be continued to complete the operation of the touched actuator can be output. There are various ways of outputting the feedback via a continuous contact of the at least one actuating element, as explained below. The output may be forward or reverse output, ie, either a remaining time until the triggering of the at least one actuating element can be output, or an already elapsed time since the start of contact of the at least one actuating element can be output.
In an advantageous embodiment of the invention, the step of outputting an optically and / or acoustically perceptible feedback via a continuous contact of the at least one actuating element comprises outputting an acoustically perceptible feedback, and the step of varying the output depending on a duration of the touch comprises changing at least one volume, an audio frequency, a frequency of a sequence of acoustic signal pulses or an acoustic output signal. For example, a shorter sequence of pulses may indicate a change in a remaining time until the at least one actuator is triggered.

In an advantageous embodiment of the invention, the step of outputting an optically and / or acoustically perceptible feedback via a continuous contact of the at least one actuating element comprises outputting an optically perceptible feedback, and the step of varying the output depending on a duration of the touch comprises changing at least one of a magnitude of an optical output, a brightness of an optical output, a color of an optical output, a blinking frequency of an optical output, a progress bar, or an optical output signal. The optically perceptible change can take place, for example, by means of a loading bar or a colored course of an indication of the touched actuating element, wherein, for example, the display of the touched actuating element changes from red to green.

In an advantageous embodiment of the invention, the step of outputting an optical and / or acoustically perceptible feedback on the touch of the at least one actuating element and the step of outputting an optically and / or acoustically perceptible feedback via a continuous contact of the at least one actuating element outputting the optically and / or acoustically perceptible feedback via an output device of the vehicle. The method can thus be carried out with a touch-sensitive control element of very simple construction, in that the touch-sensitive operating element itself only detects the contact of the at least one actuating element. The outputs can be made by appropriate output units of the vehicle.

In an advantageous embodiment of the invention, the method is terminated as soon as the contact of the at least one actuating element is stopped. The touch timer is reset for a new touch. The process returns to the beginning and waits for a new touch to be detected. In principle, a new assignment of an actuating element can take place. This is optional.

In an advantageous embodiment of the invention, the touch-sensitive control element is designed as a capacitive control element, in particular for detecting a plurality of simultaneous touches. Such capacitive controls are known as such in the prior art and are easily and inexpensively available.

The invention will be explained in more detail with reference to the accompanying drawings with reference to preferred embodiments. The illustrated features may represent an aspect of the invention both individually and in combination. Features of various embodiments are transferable from one embodiment to another.
