[0013] According to a further advantageous embodiment, the method can also include receiving a second speed, wherein the second speed is higher than the first speed. Furthermore, the method can readjust the adapted, interactive controls of the infotainment system display depending on the second speed. This allows the interactive controls of the infotainment system display to be efficiently adapted to higher vehicle speeds while driving.

[0014] According to a further advantageous embodiment, the method can also include re-determining the number of activated driver assistance systems of the vehicle, re-capturing the passenger's condition using the vehicle's interior camera, and resetting the re-adapted interactive controls of the vehicle's infotainment system display to their original interactive controls based on the determined number of activated driver assistance systems and / or the passenger's condition. This allows for an efficient resetting of the interactive controls.

[0015] According to a further advantageous embodiment, the method can also include resetting the adapted interactive controls and / or the re-adapted interactive controls to the interactive controls of the vehicle's infotainment system display if the vehicle's first speed and / or second speed falls below a predetermined speed threshold. This allows the interactive controls to be reset efficiently.

[0016] According to a further advantageous embodiment, adjusting the interactive controls can include removing a first subset of the interactive controls from the vehicle's infotainment system display while driving and / or enlarging a representation of a second subset of the interactive controls on the vehicle's infotainment system display while driving, wherein the first subset of the interactive controls preferably comprises interactive controls displayed on the infotainment system display that are linked to a predefined, first operating scenario of a first application of the vehicle's infotainment system, and wherein the second subset of the interactive controls preferably comprises interactive controls displayed on the infotainment system display that are linked to a predefined,The first operating scenario is linked to a second application of the vehicle's infotainment system. This allows interactive controls for various applications of the infotainment system to be efficiently removed, depending on one or more operating scenarios.

[0017] According to a further advantageous embodiment, the readjustment of the interactive controls can include removing a third subset of the interactive controls from the vehicle's infotainment system display while driving and / or enlarging a representation of a fourth subset of the interactive controls on the vehicle's infotainment system display while driving, wherein the third subset of the interactive controls preferably comprises interactive controls displayed on the infotainment system display that are linked to a predefined, second operating scenario of the first application of the vehicle's infotainment system, and wherein the fourth subset of the interactive controls preferably comprises interactive controls displayed on the infotainment system display that are linked to a predefined,The second operating scenario is linked to the second application of the vehicle's infotainment system. This allows interactive controls for various applications of the infotainment system to be efficiently removed, depending on one or more operating scenarios.

[0020] According to another aspect, the invention is characterized by a vehicle comprising the above-described system for adapting interactive controls of a display of an infotainment system of a vehicle during a journey with the vehicle.

[0021] Further features of the invention will become apparent from the claims, the figures, and the description of the figures. All features and combinations of features mentioned above in the description, as well as those subsequently mentioned in the description of the figures and / or shown in the figures alone, are usable not only in the combinations specified, but also in other combinations or individually.

[0022] A preferred embodiment of the invention is described below with reference to the accompanying drawings. Further details, preferred configurations, and further developments of the invention will be derived from these drawings. Specifically, the drawings schematically illustrate... Fig. 1. An exemplary method for adjusting interactive controls of a display of a vehicle's infotainment system while driving the vehicle, and Fig. 2 An example display of a vehicle's infotainment system while driving the vehicle.

[0023] In detail shows Fig. 1 An exemplary method 100 for adjusting interactive controls on a vehicle infotainment system display while the vehicle is in motion. Method 100 can adjust interactive controls on an infotainment system display depending on the vehicle's speed while driving. For example, Method 100 can reduce the number of interactive controls on the vehicle's infotainment system display depending on the vehicle's speed. Additionally, Method 100 can, for example, increase the font size of interactive controls that remain displayed on the vehicle's infotainment system display. Method 100 can revert the interactive controls to their original state if, for example, the vehicle's speed decreases, a driver assistance system is activated, and / or an alert passenger is detected.

[0024] Method 100 can receive an initial speed of the vehicle 102. The initial speed can be the vehicle's current speed while driving. Method 100 can adjust the interactive controls of the infotainment system display depending on the initial speed 104. The interactive controls of the vehicle's infotainment system display can be adjusted if the initial speed exceeds an initial, predefined speed threshold. Adjusting the interactive controls of the vehicle's infotainment system display can include reducing, for example, removing, interactive controls of the vehicle's infotainment system display after the initial speed exceeds the initial, predefined speed threshold.The interactive controls can be adapted depending on the frequency of an application scenario and / or a control scenario using an interactive control. For example, when the first predefined speed threshold is exceeded by the first speed setting, the interactive controls can be reduced to those of the navigation, media control, and communication application scenarios. Additionally, the font size of the adapted interactive controls for the navigation, media control, and communication application scenarios can be increased.

[0025] Method 100 can incrementally adjust the interactive controls of the vehicle's infotainment system display. For example, Method 100 can receive a second vehicle speed reading. This second speed could be a higher current speed of the vehicle while driving. After adjusting the interactive controls of the infotainment system display based on the first speed, the method can then adjust the adjusted interactive controls based on the second speed. Adjusting the interactive controls based on the second speed can be performed analogously to adjusting them based on the first speed.For example, if a second, predefined speed threshold is exceeded by the second speed, the adapted interactive controls can be reduced to the interactive controls of the navigation application scenario. Additionally, the font size of the again adapted interactive controls of the navigation application scenario can be increased.

[0026] Method 100 can determine the number of driver assistance systems of the vehicle that are switched on. 106 For example, Method 100 can receive an operating input from a driver of the vehicle to switch on one or more driver assistance systems while driving the vehicle and then determine the number of driver assistance systems switched on by the driver's operating input.

[0027] Finally, the method 100 can reset the adapted, interactive controls of the vehicle's infotainment system display to the interactive controls of the vehicle's infotainment system display depending on the number of the vehicle's driver assistance systems that are activated. 108 For example, for the first, predetermined speed threshold, a predetermined initial number of driver assistance systems can be specified that must be activated at a minimum for the method to reset the adapted, interactive controls to the interactive controls in their original state. For example, for the second, predetermined speed threshold, a predetermined second number of driver assistance systems can be specified that must be activated at a minimum for the method to reset the again adapted, interactive controls to the interactive controls in their original state.

[0028] Additionally or alternatively, the method 100 can detect the state of a passenger using an interior camera of the vehicle. Preferably, the detected state of the passenger is representative of an awake passenger. Furthermore, the method can additionally or alternatively reset the adapted, interactive controls of the vehicle's infotainment system display to the interactive controls of the vehicle's infotainment system display depending on the state of the passenger detected by the vehicle's interior camera.

[0029] Additionally or alternatively, procedure 100 can reset the adapted interactive controls and / or the re-adapted interactive controls to the interactive controls of the vehicle's infotainment system display in their original state if the vehicle's first speed and / or second speed falls below the first specified speed threshold and / or the second specified speed threshold.

[0030] In detail, it shows Fig. 2 An exemplary display 200 of a vehicle's infotainment system during a journey with the vehicle in different states. In an initial state 202 of the display 200, the display shows a variety of interactive controls 204 that can be operated by the vehicle's driver. In a first state 206 of the display 200, in which a first speed threshold has been exceeded by a first speed of the vehicle, the display may show a reduced number of interactive controls. In a second state 208 of the display 200, in which a second speed threshold has been exceeded by a second speed of the vehicle, the display 200 may show a further reduced number of interactive controls 204. As above with regard to Fig.As described in section 1, depending on the number of driver assistance systems activated, the detected, awake passenger, and / or the speed threshold being undershot, the interactive controls 204 can be reset to the original state 202.

[0031] Advantageously, the system can efficiently reduce the number of interactive controls depending on the speed. This effectively reduces driver distraction caused by interactive controls and thus increases driving safety. Furthermore, the system can incorporate the presence of an alert passenger. The alert passenger can assist the driver in operating the interactive controls of the infotainment system display, thereby preventing driver distraction. Automated adjustment of the interactive controls is therefore no longer necessary, allowing them to be reset to their original state. Additionally, the automated adjustment of the interactive controls can be reset if the driver activates at least a predefined, speed-dependent number of driver assistance systems.Activating the driver assistance systems increases road safety by resetting the interactive controls to their original state, allowing the driver to operate them in their original state. This improves the ease of use of the interactive controls.
