[0006] It is therefore an object of the invention to provide a function of a vehicle more efficiently on a display of the vehicle while driving. In particular, an object of the invention is to provide a quick response code of a function of a vehicle more efficiently on a display of the vehicle while driving.

[0007] This problem is solved by the features of the independent claims. Advantageous embodiments and further developments of the invention result from the dependent claims.

[0008] According to a first aspect, the invention is characterized by a method for operating a vehicle's display while the vehicle is in motion. The method can be computer-implemented and / or electronic control unit-implemented. The method comprises detecting the number of hands of a driver on the vehicle's steering wheel while the vehicle is in motion, receiving the vehicle's current speed, and disabling a function on the vehicle's display if the vehicle's current speed exceeds a predetermined speed threshold and whether or not a hand of the driver is detected on the steering wheel while the vehicle is in motion.If the function on the vehicle display is locked, the procedure includes re-detecting the number of the driver's hands on the vehicle's steering wheel while driving the vehicle, and unlocking the locked function on the display while driving the vehicle if two of the driver's hands are detected on the vehicle's steering wheel.

[0009] Advantageously, the method can provide a function and information about a function, for example a quick response code for a function, on a display of the vehicle without distracting the driver of the vehicle.

[0010] According to an advantageous embodiment, the function can provide a quick response code that can be captured by the camera of a mobile device. Capturing the quick response code allows, for example, the mobile device to be paired with the vehicle. This enables efficient control of the quick response code capture within the vehicle while driving.

[0011] According to a further advantageous embodiment, the method can also detect an additional occupant in the vehicle's interior using an interior camera and unlock the locked function on the display while driving, provided that both of the driver's hands are on the steering wheel and another occupant is detected in the vehicle's interior. This allows for the efficient unlocking of a vehicle function.

[0012] According to a further, advantageous embodiment, the detected additional occupant can be a passenger in the vehicle, and the mobile device can be the passenger's mobile device. This allows the passenger to efficiently capture a quick-response code for the function while the vehicle is in motion.

[0013] According to a further advantageous embodiment, the method can also include making the unlocked function available on the display belonging to a seat of the detected additional occupant of the vehicle. This enables the efficient capture of the function's quick response code on other displays of vehicle occupants while the vehicle is in motion.

[0014] According to another aspect, the invention is characterized by a computer-readable medium for operating a vehicle display during a journey with the vehicle, wherein the computer-readable medium comprises instructions which, when executed on a computer, perform the method described above.

[0015] According to another aspect, the invention is characterized by a system for operating a display of a vehicle while driving the vehicle, wherein the system is configured to perform the method described above.

[0016] According to another aspect, the invention is characterized by a vehicle comprising the system described above for operating a display of a vehicle while driving the vehicle.

[0017] Further features of the invention will become apparent from the claims, the figure, and the figure description. All features and combinations of features mentioned above in the description, as well as those subsequently mentioned in the figure description and / or shown in the figure alone, are usable not only in the combinations specified, but also in other combinations or individually.

[0018] The following describes a preferred embodiment of the invention with reference to the accompanying drawing. Further details, preferred configurations, and further developments of the invention will be derived from this. In detail, the drawing schematically illustrates... Fig. 1 An exemplary method for operating a vehicle display while driving the vehicle.

[0019] In detail, it shows Fig.1. An exemplary method 100 for operating a vehicle display while the vehicle is in motion. Method 100 can only provide a function and / or information on a vehicle display if the method detects that the driver of the vehicle has both hands on the steering wheel. If the driver of the vehicle has both hands on the steering wheel, the driver cannot hold a mobile device to capture information, such as a quick response code, using the mobile device.

[0020] Method 100 can detect the number of hands a driver has on the steering wheel of the vehicle while driving 102. For example, the method can detect whether the driver has no hands, one hand, or two hands on the steering wheel of the vehicle. The detection of the number of hands can be performed optically using an interior camera and / or with one or more capacitive sensors in the steering wheel of the vehicle. Method 100 can further receive the current speed of the vehicle 104.

[0021] Furthermore, procedure 100 can disable a function on the vehicle's display 106 if the vehicle's current speed exceeds a predefined speed threshold and whether or not the driver's hand is on the steering wheel is detected while driving. This function can display information on the vehicle's display. This information can be captured by an occupant's mobile device. For example, the information could be a Quick Response Code (CRC) that can be optically captured by a mobile device. Optically capturing the CRC with a mobile device allows the mobile device to be paired with the vehicle. If the function on the vehicle's display is disabled, it cannot display a CRC for pairing the mobile device. Pairing the mobile device with the vehicle is therefore no longer possible with the function disabled.

[0022] Another example of this function could be a search function in the vehicle's digital owner's manual. The search function in the digital owner's manual can be locked if the vehicle's current speed exceeds a predefined speed threshold and whether or not the driver's hand is detected on the steering wheel while driving.

[0023] Another example of this function could include manual text and / or character input while driving. Manual text and / or character input can be disabled while driving if the vehicle's current speed exceeds a predefined speed threshold and whether or not the driver's hand is detected on the steering wheel.

[0024] If the function on the vehicle display is locked, the system can re-detect the number of the driver's hands on the steering wheel while the vehicle is in motion. This re-detection can occur continuously while the vehicle is in motion. Furthermore, the system can unlock the locked function on the display while the vehicle is in motion if two of the driver's hands are detected on the steering wheel. If the function is unlocked while the vehicle is in motion, it can display information, such as a quick response code, on the vehicle display. An occupant other than the driver can use a mobile device to visually capture the quick response code with the device's camera and pair the mobile device with the vehicle while it is in motion.

[0025] If the locked function corresponds to a search function in the digital owner's manual and / or the locked function involves manual text and / or character input, Procedure 100 can unlock the locked function on the display while the vehicle is in motion 110 if two of the driver's hands are detected on the vehicle's steering wheel. If two of the driver's hands are detected on the vehicle's steering wheel, Procedure 100 assumes that operation by the driver is not possible and, if operation of the unlocked function is detected, that the function is being operated by another occupant of the vehicle other than the driver.

[0026] Advantageously, this method efficiently prevents driver distraction caused by the capture of information, such as a quick response code, with a mobile device while driving. If the driver has both hands on the steering wheel, other occupants, such as a passenger, can capture the quick response code with their respective mobile devices to pair them with the vehicle. Thus, capturing information about the function, such as the quick response code for pairing a mobile device, is efficiently enabled by this method without distracting the driver. Furthermore, the method allows other occupants to access vehicle functions that are otherwise blocked for the driver while the vehicle is in motion.
