Description

Operating device for a motor vehicle for selecting and / or setting an operating function, wherein an optical symbol on a first or second

Display unit is displayed, driver assistance system, motor vehicle and method

The invention relates to an operating device for a motor vehicle with a

Operating element for selecting and / or setting an operating function of a

Functional unit of the motor vehicle. The operating device has a first

Display unit, which is arranged locally spaced from the operating element. Furthermore, the invention relates to a driver assistance system, a motor vehicle and a method.

Operating devices are already known from the prior art, which are designed for setting and / or selecting an operating function of a functional unit of a motor vehicle. In particular, symbols for the functional unit of the operating element are displayed directly or indirectly in the operating elements to be actuated. Since, in particular, the operating elements are not in the field of vision of the operator, who may be a driver of the motor vehicle in particular, the operator must turn his gaze to the operating element in order to select and / or set the functional unit and corresponding operating function. As a result, in particular, the driver of the motor vehicle can be distracted from his driving task, which can lead to a critical situation in traffic.

Object of the present invention is an operating device, a

Driver assistance system to provide a motor vehicle and a method, which or which allows reliable operation of the operating device with minimal distraction of the operator.

This object is achieved by an operating device, a driver assistance system, a motor vehicle and by a method according to the independent claims.

One aspect of the invention relates to an operating device for a motor vehicle, having an operating element for selecting and / or setting an operating function of a vehicle

Functional unit of the motor vehicle. The operating device has a first

Display unit, which is arranged locally spaced from the operating element. The operating device has a second display unit, which is separate from the first display unit and, in particular, arranged at a distance from the operating element in a spatially spaced-apart manner. The operating device is designed such that at least one of the selected

Operating function characterizing optical symbol depending on a

Decision criterion is displayed on the first display unit or the second display unit.

In particular, this makes it possible for the optical symbol characterizing the operating function to be displayed selectively on the first or the second display unit. In this way, depending on the decision criterion, it can be decided on which display unit the optical symbol characterizing the operating function is displayed, in which the operator of the operating device is the least distracted, or on whose basis the simplest perceptibility without circumferential position change is made possible for him. In particular, should the operator be the driver of the motor vehicle, so is the driver

For example, only slightly distracted from his driving task, so that the safety in road traffic is increased.

As a functional unit of the motor vehicle, for example, a flashing device, a windscreen wiping device, a lighting device, an infotainment system or a communication device can be considered. The listed functional units are given by way of example only and are not to be considered as conclusive.

It has proved to be advantageous if a line of sight of an operator of the

Operating device by means of a first detection device, which is designed in particular as a camera, the control device and / or the motor vehicle is detected, and depending on the viewing direction as a decision criterion that the operating function characterizing optical symbol on the first display unit or the second display unit is displayed. Since, in particular, the driving task of a motor vehicle is dependent on the viewing direction of the driver, the viewing direction is thus as

Decision criterion important information in order to decide on which display unit the optical function characterizing optical symbol is displayed, so that the deflection of the driving task is as low as possible or a change in the viewing direction may have to be made very low to perceive the optical symbol to be able to. In accordance with a further advantageous embodiment, the optical symbol characterizing the operating function can be displayed on that display unit which is in the region of the detected line of vision

Operating function characterizing optical symbol displayed such that it is displayed on that display unit, which lies substantially in the line of sight of the operator, in particular in the line of sight of the operator. In particular, a particularly small deflection of the operator, in particular the driver of the driving task, can be realized thereby. Due to the small deflection of the operator can thus be made safer, especially when driving the motor vehicle traffic.

It is also advantageous if the operating device has a control unit which is designed so that, when the viewing angle changes, it is decided whether the display of the optical symbol continues on the previous display unit or if the display is displayed on another display unit. In particular, it is thus provided that the optical symbol characterizing the operating function is displayed on that display unit which is closest to the detected viewing direction, so that the optical symbol characterizing the operating function is displayed on the display unit which is substantially in the viewing direction of the operator, in particular the line of sight of the operator, lies. In particular, the viewing direction change can then be detected in a viewing direction change from a first viewing direction of the operator to a second viewing direction of the operator, and the optical symbol characterizing the operating function can be displayed on that display unit which after the viewing direction change essentially in the second viewing direction of the operator, in particular the second line of sight of the operator lies. This can also change the direction of the

Operating function characterizing optical symbol advantageously displayed on the current viewing direction closest display unit. As a result, the visual symbol characterizing the optical function can be quickly viewed by the operator even when changing the direction of view, so that in particular in a driving task of the operator this can select the operating function and is minimally distracted. Thus, a dynamic change of the display location of the optical symbol is dependent on a the position of the operator, in particular a body part, in particular the eyes, characterizing parameters possible.

According to a further advantageous embodiment, the first display unit as a head-up display unit and / or as a center console display unit and / or as Instrument cluster display unit formed and / or the second display unit is designed as a head-up display unit and / or as a center console display unit and / or as an instrument cluster display unit. In the head-up display unit, which may also be referred to as a head-up display, it may be both a display unit with a so-called combination mirror as a projection surface, as well as to such a display unit, which the windshield as

Uses projection screen. It is also possible that the first display unit and / or the second display unit is designed as an on-head-mounted display unit (head mounted display). By means of this embodiment, the at least two display units can thus lie in several viewing areas of the operator, so that it is possible to select from a plurality of display units. In particular, it is then provided that that display unit is selected for the display of the optical symbol characterizing the operating function, which in particular in the

Essentially in the line of sight of the operator. This makes it possible for the operator to select from the plurality of display units installed in the motor vehicle that display unit which deflects the operator as little as possible from his actual task.

It has also proved to be advantageous if the operating element has a plurality of regions, wherein each region is assigned a respective operating option, wherein upon detection of an approach of the operator to the operating element and / or a touch of the operating element by means of a first detection device and / or a second detection device, the plurality of operating options is displayed on the respective display unit as at least one optical symbol. In particular, it is provided that the plurality of operating options is indicated by a plurality of optical symbols on the respective display unit. In particular, the plurality of operating options and likewise a plurality of functional units can thus be operated with one operating element. By the respective display on the respective display unit, the majority of the operating options can then be displayed on the one display unit in a particularly simple and comfortable manner. As a result, a small deflection of the operator, in particular the driver, realized. Thus, a

Operation of the operating device can be realized with little distraction of the operator. In particular, the first detection device can be designed as a camera and capture the approach and / or the touch by means of image processing.

In particular, the second detection device can be designed as a proximity sensor and / or touch-sensitive sensor and the approach and / or

Detect touch of the control. According to a further advantageous embodiment, a position of a finger of an operator relative to the operating element can be detected by a detection device and the detected relative position of the finger to the operating element can be displayed on the respective display unit. Thus, without having to look at his hand and at the operating element, the operator can see the position of the finger on the respective display unit, so that reliable operation of the desired operating option or the desired functional unit can be realized with little distraction from the actual task , As a result, the operator experiences only a slight deflection, in particular of the driving task, so that the safety in traffic can be further increased by means of this embodiment. In particular, it is therefore provided that the position of the finger in "real time"

for example, as a point on the respective display unit can be displayed. It is also possible that the finger position change color depending on whether the current position of the finger is a valid input or not. For example, this can be done from red as an invalid input to green to a valid input.

It is also advantageous if the detection device is designed as a capacitive sensor and / or as a camera and / or as a heat sensor. In particular, a precise position detection, for example of the finger or an approach or contact, can be carried out by means of these detection devices. As a result, the operating device can be operated reliably and accurately.

According to a further advantageous embodiment, depending on an operating status of the functional unit and / or depending on the actuation of the

Control element, the optical symbol on the respective display unit with respect to the color and / or size and / or the Darstellungsart displayed differently and upon actuation of the control element and / or upon operation of the functional unit is an optical and / or acoustic and / or haptic by the operating device Feedback can be generated for an operator. In particular, the operating state of the functional unit can thus be displayed to the operator in several ways and / or, upon actuation of the functional unit, the operator can be given feedback that the functional unit has been operated. In particular, this is done with minimal distraction of the operator, so that this can focus in particular on the driving task. Thus, the safety in road traffic is increased. Preferably, at least one further operating option and / or a further optical symbol for the operating device can be generated personalized by an operator. For example, for this purpose, the operator can freely define individual optical symbols for, for example, the favorite station on the radio, for telephone numbers or for destinations such as "driving home"

Operating device increases. This can also reduce the

Equipment variants take place because fewer controls are installed in the motor vehicle, since the operating device provides a plurality of operating options available, so that the icons are also displayed only situational. Reducing the trim levels can also reduce complexity so that the operator is less distracted from his or her actual driving task. It is possible that the control element is assigned no or a higher-level symbol. The actually deposited optical symbols can then be displayed on the display units depending on the variant.

It is also advantageous if the operating device as a steering wheel switch and / or as a steering column switch and / or as a light rotary switch and / or windows and / or as a center console switch and / or Sitzverstellschalter and / or as

Steering column adjustment is formed. These switch variations are, in particular, switches which would exert a great deal of distraction on the operator when looking at the respective switches. As a result, attention can not be directed to the operating element itself, but rather to the respective display unit, in particular with these switches, as a result of which the deflection, in particular of the driving task, is reduced.

Furthermore, an aspect of the invention relates to a motor vehicle with an operating device. The motor vehicle is designed in particular as a passenger vehicle.

One aspect of the invention relates to a method for operating an operating device for a motor vehicle, wherein an operating function of a functional unit of the motor vehicle is adjusted and / or selected by means of a control element of the operating device. The operating device has a first display unit of
