[0005] Method for detecting a driving event of a two-wheeler and system for detecting such an event

[0006] State of the art

[0007] The present invention relates to a method for detecting a driving event involving a two-wheeler. The present invention also relates to a system for detecting a driving event involving a two-wheeler.

[0008] Two-wheeled vehicles equipped with acceleration sensors are known from the prior art. Certain driving events, such as a collision, can be deduced from the signal profiles of these acceleration sensors. However, the sequence or course of such a driving event cannot usually be deduced.

[0009] Disclosure of the invention

[0010] According to the invention, a method with the features of the independent claim is provided. Such a method offers the advantage that the course or progression of a driving event can be determined more reliably than with methods known from the prior art. Furthermore, more detailed information concerning a driving event involving a two-wheeler can be provided.

[0011] The inventive method for detecting a driving event of a two-wheeler comprises a step of detecting a lean angle of the two-wheeler and a step of detecting at least one further driving dynamics parameter of the R. 417644

[0012] - 2 -

[0013] Two-wheeler. It further includes assigning the lean angle and the driving dynamics parameter to a driving state of the two-wheeler. It also includes determining a driving event from a driving state of the two-wheeler or a sequence of driving states of the two-wheeler.

[0014] Further advantageous embodiments of the present invention are the subject of the dependent claims.

[0015] It should be noted here that a vehicle dynamics parameter of a two-wheeler is understood to be a parameter suitable for describing the vehicle dynamics of the two-wheeler. This can be, for example, the speed, acceleration, deceleration, or direction of travel of the two-wheeler. The lean angle, for instance, is very well suited as a descriptive parameter, since it is constantly changing on a two-wheeler, and events that occurred during the subsequent course of the process can be determined relatively easily from the lean angle. With a four-wheeled motor vehicle, the lean angle generally does not change or changes only slightly, which is why it plays only a subordinate role as a descriptive parameter there.

[0016] It should also be noted that a driving condition of a two-wheeler is understood to be a state that describes a currently existing driving situation and can be described in particular by driving dynamic parameters. This can be, for example, cornering, acceleration, or deceleration.

[0017] Furthermore, it should be noted that a driving event is understood to be an event that describes a change in the driving state. This change can occur over a defined period of time, or it can be a change from one state to another—in other words, a sequence of driving states. It should also be noted that a constant driving state can be understood as a driving event. Therefore, a driving event can also be inferred even if there is no sequence of states. For example, driving straight ahead at a constant speed for a period of 20 seconds. R. 417644

[0018] - 3 -

[0019] It should also be noted that a driving event can be determined from one or more driving states. Such a driving event may not be describable solely by vehicle dynamics parameters. For example, consider a motorcyclist who stops at a red light. Part of this event typically involves the rider placing their foot on the ground. This foot placement is not detected by sensors, but it is a typical component of such a driving event. The description of a driving event can be supplemented with expert knowledge to incorporate information that is not detectable by sensors, or only with considerable effort, into the determination of the driving state.

[0020] It is advantageous if the assignment of changes in lean angle and the vehicle dynamics parameter to a driving state of the two-wheeler is carried out by comparison with stored values, wherein the values ​​are stored in a database and / or state table. In this way, an assignment can be implemented using simple technical means. The stored values ​​can also be easily supplemented or adjusted by a person skilled in the art. The stored values ​​can thus be kept up to date with the current state of the art. In a further embodiment, it is advantageous if input from the rider of the two-wheeler is recorded and the driving event is additionally determined from the rider's input. A rider's input represents an additional parameter based on which the driving event can be determined, and the accuracy of the determination is improved.Such an input could be, for example, the activation of a brake, a direction signal transmitter, or a throttle lever.

[0021] It is advantageous to capture an output from an assistance system and to further determine the driving event using this output. An output from an assistance system represents an additional parameter by which the driving event can be determined, thus improving the accuracy of the determination. Depending on their type, driver assistance systems can recognize a driving event. This recognition can be used to exclude certain driving events and to determine a present driving event more accurately and quickly. For example, if a fall is detected, fall detection can be used to exclude other events when determining the driving event. (R. 417644)

[0023] It is possible that the driver of the two-wheeler is still sitting on that two-wheeler and is carrying out an upright ride on two wheels.

[0024] In a further embodiment, it is advantageous if the determination of the driving event from a driving state of the two-wheeler or a sequence of driving states of the two-wheeler is carried out by comparison with further stored values, wherein the further values ​​are stored in a further database and / or event table. In this way, an assignment can be implemented using simple technical means. The stored values ​​can also be easily supplemented or adapted by a person skilled in the art. The stored values ​​can thus be kept up to date with the current state of the art. It is also conceivable that the determination can be carried out in this way in different systems in which the values ​​can be stored.

[0025] It is advantageous if the driving incident is an emergency situation for the rider of the two-wheeler, particularly an accident, and / or a hazardous situation for other road users. Such incidents pose a danger to the safety of the rider and / or other road users. It is advantageous if these can be reliably detected.

[0026] The present invention also relates to a system for detecting a driving event of a two-wheeler. This system comprises either a first detection device configured to detect a lean angle of the two-wheeler and a second detection device configured to detect at least one further driving dynamics parameter of the two-wheeler, or a first detection device configured to detect a lean angle of the two-wheeler and at least one further driving dynamics parameter of the two-wheeler.It further comprises either a first transmission device configured to transmit the detected lean angle of the two-wheeler to an evaluation unit and a second transmission device configured to transmit the detected at least one further vehicle dynamics parameter of the two-wheeler to an evaluation unit, or a transmission device configured to transmit the detected lean angle and the detected at least one further vehicle dynamics parameter of the two-wheeler to an evaluation unit. The system further comprises an evaluation unit that includes a [R. 417644].

[0028] is designed to assign a driving condition to the lean angle and the driving dynamics parameter and is further equipped to assign a driving event to at least one driving condition and / or a sequence of at least two driving conditions of the two-wheeler.

[0029] Using such a system, the described procedure can be implemented and integrated into a two-wheeler. It is conceivable that in such a system, the parameters could be transmitted via a cITS infrastructure in a cITS-specific data format.

[0030] It is advantageous if the evaluation unit can be integrated into another road user's system and / or a data processing system, particularly a cloud-based data processing system. For example, a two-wheeler can transmit the recorded lean angle and other driving dynamics parameters to another road user, who can then identify a driving event of the two-wheeler and, for instance, compare it with their own table of values ​​or database to determine only those events relevant to that road user. The transmission of the recorded data can occur in a defined standard format, which facilitates evaluation for the other road user. This could, for example, be a data format according to the C-ITS standard. It should be noted that it is also conceivable to record and transmit input from the two-wheeler's rider.It is also conceivable to record and transmit output from assistance systems. It is further advantageous if the evaluation unit is designed to generate a warning message that can be output to at least one other road user via an output unit. In this way, for example, the driver of another vehicle can be warned if an accident involving a two-wheeler has been detected. This can serve to prevent the driver from being involved in the accident themselves because the accident scene is not yet secured, or the driver can be called upon to provide assistance. Pedestrians or cyclists can also be considered other road users, who can then be called upon to provide assistance if necessary. In the case of vehicles, existing acoustic and / or output devices already present in the vehicle can be used as output units.This can be et-R. 417644.

[0031] - 6 -

[0032] The information could be displayed in the instrument cluster or through the speakers. In the case of pedestrians or cyclists, output via a smartphone would be conceivable.

[0033] It is advantageous if the devices for detecting and transmitting the lean angle and at least one other driving dynamics parameter are integrated into a two-wheeler. Such a two-wheeler can then inform other road users about an incident, and help can be requested. Particularly in the event of an accident, motorcyclists can be separated from their vehicles, and injuries requiring rapid assistance are often to be expected. Furthermore, a crashed two-wheeler is more easily overlooked than a crashed car; such a system is therefore advantageous for two-wheelers.

[0034] In other words, the inventive method and system enable the inventive method and system to infer events from sequentially transmitted vehicle data. By assigning the vehicle data, particularly its changes over time, to stored values, adaptation to continuously changing values ​​is possible. Using these new values, a driving event can be inferred with greater certainty. In this way, driving events can also be identified that include actions and / or states of a two-wheeler rider that cannot be detected by sensors. For example, a rider whose two-wheeler has fallen over will typically stand next to their vehicle and try to right it. In such an event, people on the road are to be expected.

[0035] In the event of an accident, for example, the direction and speed of travel can be used to determine whether a rider was thrown from their motorcycle and how far away they came to rest. This information can be particularly relevant for emergency responders and save time during a rescue operation.

[0036] Brief description of the drawings

[0037] Exemplary embodiments of the invention are shown in the drawings and explained in more detail in the following description. R. 417644

[0038] - 7 -

[0039] Figure 1 is a schematic representation of a driving event, based on which a method according to the invention is explained.

[0040] Figure 2 is a schematic representation of a driving event, based on which a method according to the invention is explained.

[0041] Figure 3 shows a schematic representation of a method according to an embodiment of the invention.

[0042] Figures 1 and 2 schematically show two different points in time of a driving event in a top-down view, which serve as a basis for describing the procedure with possible additions. Figure 1 shows a two-wheeler 100 with a rider 101, traveling on road 1000 and approaching a traffic light 1001. The lean angle of the two-wheeler 100 is constant, and its speed decreases continuously. These parameters can now be transmitted, for example, via radio to the other road users 200 and 300 using the transmission unit 102. Road user 200 is a car approaching the two-wheeler 100 on road 1000. Road user 300 is a pedestrian. The car 200 has an evaluation unit 201, which is configured to receive the parameters transmitted by the transmission unit 102 and assign them to a driving event.Furthermore, the evaluation unit 201 can also be configured to provide a warning signal and / or information to the driver of the car 200. It is conceivable that the evaluation unit 201 is integrated into the instrument cluster of the car 200.

[0043] The pedestrian 300 has the evaluation unit 301, which is also configured to assign a driving event and output information to the pedestrian 300. This could, for example, be a smartphone.

[0044] From the transmitted parameters, the event can now be assigned that indicates the two-wheeler 100 is approaching a traffic light 1001. If its speed is zero and the lean angle remains constant, the event can be assigned that the two-wheeler 100 has come to a standstill and is stopped at the traffic light 1001. DasR. 417644

[0045] - 8 -

[0046] Attributing this driving event could be made more precise, for example, by processing GPS data that includes a route profile with the location data of objects relevant to road traffic, such as traffic lights 1001.

[0047] It is also conceivable that the two-wheeler 100 includes an evaluation unit 103, which can also assign driving events and provide this information to the driver 101 of the two-wheeler 100. Furthermore, it is also conceivable that the transmission unit 102 transmits the recorded parameters to a cloud 400, where the assignment of the driving event takes place. In this scenario, the driving event could be transmitted from the cloud 400 to the other road users 200 and 300 without them needing to include an evaluation unit 201 or 301 themselves to perform the assignment. In this case, only information about the driving event could be issued to the other road users 200 and 300.

[0048] Figure 2 shows the driving situation at a later time. The two-wheeler 100 fell over at the traffic light 1001. As a result, an abrupt change in the lean angle was detected at a recorded speed of zero. From this, it can be deduced that the two-wheeler 100 has fallen over. Furthermore, it can be deduced that the rider 101 is no longer sitting on the two-wheeler 100, but is in its vicinity. The driving event that the two-wheeler 100 has fallen over, the rider 101 needs help, and there is a high probability that people are on the road 1000 can be assigned by one of the evaluation units 103, 201, 301, or 400.

[0049] This driving incident can now be communicated to other road users 200 and 300 by evaluation units 201 and 301. Road user 300 may be called upon to provide assistance and can either offer medical help or assist driver 101 in righting the two-wheeler 100. Road user 200, in turn, may also be called upon to provide assistance and / or be informed about the driving incident and warned that there might be people on the road 1000 and that they must reduce their speed. In the further course of the driving incident, it is conceivable that the two-wheeler 100 will right itself, which is again detected by a change in its lean angle. DenR. 417644

[0051] Other road users (200, 300) can then be informed that the driving situation has changed to a less critical situation.

[0052] Figure 3 schematically shows a process sequence according to an embodiment of the invention. The process begins with step 500. In step 501, the lean angle of the two-wheeler is detected, and in step 502, another driving dynamics parameter of the two-wheeler is detected. In step 503, a driving condition is assigned to the lean angle detected in step 501 and the other driving dynamics parameter detected in step 502. This assignment can be made using a database in which corresponding values ​​are stored. In step 504, a driving event can be determined. This determination can also be made using a database in which corresponding values ​​are stored. The process ends with step 505 and can be repeated.

[0053] Figure 4 schematically shows a further process sequence according to an embodiment of the invention with advantageous additions. The process begins with step 500, and in steps 501 and 502, the lean angle or another vehicle dynamics parameter of the two-wheeler is recorded. In step 512, the recorded lean angle and the recorded vehicle dynamics parameter are transmitted to an evaluation unit. This transmission can take place, for example, via radio or mobile communication. The recorded lean angle and the recorded vehicle dynamics parameter can be transmitted in a standardized data format. It is advantageous if the transmission is carried out according to the CITS standard. The evaluation unit can be integrated into a system of another road user, for example, a driver information system of a car or a pedestrian's smartphone. In step 503, a driving state is assigned to the parameters recorded in steps 501 and 502.In step 504, the data is assigned to a driving event. In step 514, a warning message is issued to the other road user whose evaluation unit has received the parameters transmitted in step 512. The message can be issued, for example, audibly or visually. The process ends with step 505 and can be repeated.
