Embodiment. The process 700 is related to the

A method of warning of Fig. 2 or a similar method. In this case, the process 700 for warning is performed for a vehicle whose role of a wrong-way situation is that of the wrong-traveling vehicle. The role of the vehicle can be referred to as the first role.

Process 700 begins at block 701. Thereafter, at block 702, normal execution is determined. Subsequently, at a block 703, an event occurs in which a driver of the vehicle enters the highway in the wrong direction. Thereupon, in a block 704, for example, in a

Cloud or cloud triggered an alarm or a warning for the first role or role as a wrong-way driver. In this case, the wrong-way signal can be transmitted. Then, the process 700 enters a higher-level block 705 in which, inter alia, a warning screen or first screen is displayed. Of the

The warning screen is similar or similar to the screen of FIG. 3. In a block 706, the warning screen is displayed. Then, in a block 707, it is checked if audio is output. If so, a warning sound is played back at block 708, for example, a beep at 1

Second duration. Thereupon, at a block 709, another warning sound is sounded played, for example "you drive in the wrong direction! Stop at the next edge of the road. "The further warning tone can be played repeatedly with a pause between repetitions of 1 second, and the further warning tone is played back at least once, even if the warning tone is off

Screen changes to the second screen or a user

Push button at an interface. Thereafter, process 700 proceeds to block 710, which is reached directly after block 707 if the check indicates that a sound is disabled. In block 710, a check is made as to whether the vehicle is stopping. If so, the process proceeds to a block 711 which checks to see if the first screen has been displayed for at least 30 seconds, for example. If not, process 700 loops through block 711 until the condition is met. If the first

Screen has been displayed for 30 seconds, the process 700 proceeds to a block 712, at which the warning tone or beep is played,

for example, with a duration of 1 second simultaneously with a change of the screen or the display. If the check in the block 710 shows that the vehicle is not stopping, the process 700 transfers from the block 710 to a block 713, in which it is checked whether a user has triggered a change of the display, for example by wiping. If not, process 700 proceeds to block 714, where it is checked if the

User discards the warning. If not, process 700 proceeds to block 715, where it is detected if the user presses the back button. If not, then the process 700 loops back to the block 706. After the block 712 or when it is determined in the block 713 that the

User has triggered the change of display, the process 700 proceeds to a higher-level block 716, in which among other things

Recommendation screen or a recommendation ad or a second

Screen or a second screen is displayed. In a block 717, recommendations are shown. The recommendations correspond to the second display corresponds to the display of Fig. 4 or a similar display. After block 717, a block 718 follows, in which it is checked whether the user, for example by swiping, changes to the previous one

Screen has triggered. If so, the process 700 loops back to the block 706. If not, the process 700 transfers from the block 718 to a block 719 which checks to see if the user is alerting rejects. If not, process 700 proceeds to block 720 where it is determined if the user presses the back button. If not, process 700 returns to block 717.

In the course of the process 700, a higher-level block 721 follows, in which inter alia a banner display or a third display is displayed. If it is determined in block 719 that the user discards the warning, process 700 proceeds to block 722, where it is determined if the alert is still active. If so, a block 723 indicates that a notification is available at a notification center. If not, then in block 724 the warning is turned on

Notification area deleted. Block 722 is also reached directly from block 714 if it has been determined that the user is discarding the warning. If it is determined in block 720 that the user presses the back button, then the process moves to block 725 where a banner with the alert is displayed on a screen. From block 725, process 700 proceeds to block 726, where it is determined whether the alert is still active. If so, the process 700 loops back to the block 725. The block 725 is also reached directly from the block 715 when it is detected that the user presses the back button.

Thereafter, process 700 proceeds from block 723, block 724, or if it is determined in block 726 that the alert is no longer active, to block 727, where a normal expiration is detected. Finally, the process 700 ends after the block 727 at a block 728.

FIG. 8 shows a flowchart of a warning process 800 according to one embodiment. The process 800 is related to the

A method of warning of Fig. 2 or a similar method. In this case, the process 800 for warning is performed for a vehicle whose role of a wrong-way situation is that of a vehicle affected by a wrong-way other vehicle. Thus, the process 800 for alerting is similar to the process of FIG. 7.

Process 800 begins at block 801. Thereafter, normal execution is detected at block 802. Subsequently, a block 803 occurs Event in which a wrong-way driver is detected in the environment. Thereupon, in a block 804, for example in a computer cloud or cloud, an alarm or a warning is triggered for the second or third role or the role as the victim of a wrong-way driver or potentially affected person of a wrong-way driver. In this case, the wrong-way signal can be transmitted.

Then, the process 800 enters a higher-level block 805 in which inter alia a warning screen or first screen is displayed. Of the

The warning screen is similar to or similar to the screen of FIG. 5. In a block 806, the warning screen is displayed. Then it is checked in a block 807 whether a sound or an audio output is activated. If so, a warning sound is played back at block 808, for example, a 1 second beep, particularly at the same time as the display is changed. Thereafter, process 800 proceeds to block 809, which is also reached by block 807 if the check indicates that a sound is disabled. In block 809, it is determined whether a user has triggered a change of display, for example by swiping. If not, the process 800 proceeds to a block 810 which checks to see if the user discards the alert. If not, process 800 proceeds to block 811, where it is detected if the user presses the back button. If not, process 800 returns to block 806.

If it is determined in block 809 that the user has triggered the change of display, the process 800 proceeds to a parent block 812, which includes, but is not limited to, a recommendation screen

Recommendation screen or a second screen or display. In block 813, recommendations are shown. The

Recommendations correspond or the second display corresponds to the display of Fig. 6 or a similar display. After block 813, block 814 follows, in which it is checked whether the user has triggered, for example by swiping, a change to the previous screen. If so, the process 800 loops back to the block 806. If not, the process 800 transfers from the block 814 to a block 815 which checks to see if the user discards the warning. If not, then the process 800 transfers to a block 816 where it is determined whether the user has the Back button presses. If not, process 800 returns to block 813.

In the course of the process 800, a higher-level block 817 follows, in which inter alia a banner display or a third display is displayed.

If it is determined in block 815 that the user discards the alert, process 800 proceeds to block 818 where it is determined if the alert is still active. If so, a block 819 indicates that a notification is available in a notification center. If not, then in block 820 the warning is turned on

Notification area deleted. Block 818 is also reached directly from block 810 if it has been determined that the user is discarding the warning. If it is determined in block 816 that the user presses the back button, then process 800 proceeds to block 821 where a banner with the alert is displayed on a screen. From the block

821, process 800 proceeds to block 822 which determines if the alert is still active. If so, the process 800 loops back to the block 821, the block 821 is also reached directly from the block 811 when it is detected that the user presses the back button.

Thereafter, process 800 proceeds from block 819, block 820, or if it is determined in block 822 that the alert is no longer active, to block 823, where a normal expiration is detected. Finally, process 800 ends after block 823 at block 824.

With reference to FIGS. 1 to 8, background and exemplary embodiments as well as advantages will be summarized below and / or explained in other words. In particular, a distinction is made between three different roles, the one

Vehicle 110 or a driver can take. Role 1: The vehicle 110 or the driver of the same becomes the wrong-way driver. Will a driver as

False driver identified, he receives through the warning system 120 and the

Method 200 provides a warning and first behavioral recommendations that may be adjusted after stopping the vehicle 110 so that the driver is assisted until he has left the dangerous situation. Also, one can Warning message to surrounding road users to be sent. Role 2: The vehicle 110 is on the same road as a wrong-way driver, there is a risk of collision. The driver receives by the warning system 120 and the method 200, the warning of a wrong-way driver on his route and can be displayed further behavior recommendations. Role 3: The vehicle is driving a road near a wrong-way driver. B. the opposite lane or another road. There is no risk of collision. The driver receives through the warning system 120 and the

Method 200 is an indication of the wrong-way driver and the road he should avoid, otherwise he runs the risk of colliding with the wrong-way driver.

Recommendations, which are given to the driver of the respective role, come in particular from official sources, such as the

Ministry of Transport. For the first role, the alert is the first priority, then the recommendations are displayed. A voice message can additionally support the driver. For the second role, the alert is also the first priority, and then additional information is displayed and optional recommendations are given. For the third role, the driver receives information about a wrong-way driver on another nearby section. Optionally, recommendations are given.

According to embodiments, therefore, a logic can be provided which allows a quick and accurate warning and behavioral recommendation. Fast warnings and behavioral recommendations can reduce a number of accidents caused by wrong-way driving and can also assist wrong-way drivers and all drivers in the area who are warned.

If an exemplary embodiment comprises a "and / or" link between a first feature and a second feature, then this is to be read so that the embodiment according to one embodiment, both the first feature and the second feature and according to another embodiment either only first feature or only the second feature.
