The invention relates to a system and a method for warning against dangerous situations in traffic

Situations in the traffic.

The increasingly dense road traffic creates a variety of dangerous situations. The previously known means of warning drivers against danger spots and dangerous situations, such as Traffic information is inadequate, because (too) a lot of time can pass between the time of the occurrence of the danger and the time at which the drivers are warned. In addition, the efficiency of the system depends on many, especially random, factors, particularly when a hazard or danger point is detected and the entity responsible for disseminating an alert is reported.

US 2013/321 179 A1, US 201 1/0063129 A1 and CN 103 208 205 A describe systems which are designed to recognize danger spots and warn the drivers of other vehicles. For this, the participating vehicles are equipped with suitable transceivers.

It is desirable to provide an improved system and method for warning of dangerous situations in traffic which makes it possible to warn even drivers who do not have a suitable receiving device as reliably and quickly as possible of danger spots.

An embodiment of a system for warning against dangerous

Situations in traffic include at least one position sensor that is configured to detect the current position of a vehicle and

Provide location data; at least one driving condition sensor configured to detect at least one driving condition of the vehicle and to provide driving condition data; a transmitting unit configured to transmit the position data and / or the driving condition data; a recognition unit which is designed to detect a potentially dangerous situation by evaluating the position data and / or the driving status data; a receiving unit configured to receive information about a potentially dangerous situation in the vicinity of the vehicle; and at least one display device configured to display information about a potentially hazardous situation. In this case, the at least one display device is designed, in particular, to warn the drivers of other vehicles of the potentially dangerous situation.

In one embodiment of the invention, a method for warning of dangerous situations in traffic includes: detecting the current position of a vehicle having at least one position sensor and providing vehicle position data; detecting at least one driving condition of the vehicle with at least one driving condition sensor and providing driving status data; to send the vehicle position data and / or the driving status data; to recognize a potentially dangerous situation from the vehicle position data and / or the driving condition data; Receiving information about a potentially hazardous situation in the vicinity of the vehicle; and indicate a potentially dangerous situation in the vicinity of the vehicle. In particular, the method comprises displaying the information in such a way that also the drivers of other vehicles are warned of the potentially dangerous situation.

According to embodiments of the invention, driving state information transmitted from individual vehicles is used. Do the driving condition information of different vehicles in a short period of time at the (approximately) same location have the same or similar abnormalities, such. B. strong braking, automatic stability control (ESP) activations, sudden steering, etc., on, can be closed to a point of danger at this location. This information is used to warn drivers who are about to reach the identified danger spot in front of the danger spot. In particular, the drivers of vehicles, which have no receiving device for the information, are alerted by warning signals to the imminent danger.

In this way, hazards in traffic can be automatically identified and disseminated in a short time. In particular, not only the drivers of networked vehicles, which are able to receive the information about the danger spots directly, but also the driver of non-networked vehicles can be reliably and quickly warned of the danger spots, without manual intervention, which is often the cause of Time delays is necessary. In this way, for example, the - -

Dangers of subsequent accidents at the end of traffic jams, accidents due to obstacles on the road and / or due to a smooth or soiled road are considerably reduced. In one embodiment, the transmitting unit is designed to protect the vehicle

To transfer position data and / or the driving condition data to a central server. The recognition unit is provided in the central server and configured to receive driving condition information from a plurality of vehicles. By merging the data of a large number of vehicles in a central server, the traffic situation can be well recorded.

In this way, possible danger spots in traffic can be identified particularly safely and reliably.

In another embodiment, the detection unit is formed in the vehicle, the transmission unit is configured to transmit the vehicle position data and / or the driving status data to the reception units of other vehicles; and the receiving unit is configured to receive the vehicle position data and / or the driving status data from the transmitting units of other vehicles. In this embodiment, the reliability of the system is particularly high, since the operation is not dependent on the functionality of a central server and the functionality of the connection to the central server. In particular, vehicles in the vicinity of the sending vehicle can be warned in this way quickly and reliably against dangerous situations.

In one embodiment, the recognition unit is designed to evaluate the vehicle position data and / or the driving status data of a plurality of vehicles in order to detect a potentially dangerous situation. Outliers caused by individual vehicles which are not based on the current traffic situation can thus be recognized and excluded from the evaluation.

The automatic detection of danger spots and dangerous situations can be further improved in this way.

In one embodiment, the transmitting unit is configured to transmit the position data and / or the driving condition data only when the driving condition data deviates from a usual driving profile. In this way, the data transmission is limited to the transmission of potentially reliant data and the data connection is relieved. In addition, the data transmission - - incurred costs are reduced. In particular, the driving profile may include acceleration and braking values, automatic stability control (ESP) data and / or anti-lock braking system (ABS) data to detect exceptional driving conditions such as full braking or aquaplaning.

In one embodiment, the system includes an image capture device, and the transmit unit is configured to transmit image data captured by the image capture device. The image pickup device can be aligned in particular in the direction of travel. Images of the supposed danger spot can be taken with the image recording device and transmitted together with the position and driving state data. By, possibly automatic, evaluation of the transmitted image information can be even better decided whether and what kind of danger point exists.

In one embodiment, the display device comprises a flashlight, a hazard warning system, a horn and / or a graphic display device in order to make the driver or drivers aware of a dangerous situation visually or acoustically.

In one embodiment, the detection unit is designed to automatically detect whether the danger point is an accident site in order to trigger an emergency call in this case. In this way rescue workers can be sent to the scene of the accident particularly quickly and reliably. By transmitting the current vehicle position data of the vehicle, the accident site can be located particularly fast, reliable and accurate.

Embodiments of the invention are explained in more detail below with reference to the attached figures:

figure description

Figure 1 shows a first embodiment of a system according to the invention for warning against dangerous situations in traffic in a schematic representation.

In a first vehicle 10, at least one position sensor 14 and at least one driving state sensor 16 are arranged.

The position sensor 14 is configured to determine the current position of the vehicle 10 and to provide vehicle position data.

The driving state sensor 16 is designed to detect at least one driving state of the vehicle 10, for example its acceleration, and to provide driving state data of the vehicle 10.

The vehicle 10 also has a transmission unit 12 which is designed to transmit the data provided by the at least one position sensor 14 and the at least one driving state sensor 16. The transmitting unit 12 can be designed, in particular, to transmit the data via a mobile radio network.

In the vehicle 10, an optional image pickup device 15 is additionally provided, which is designed to receive image data, in particular in the direction of travel of the vehicle 10, and to make it available to the transmitting unit 12, so that the transmitting unit 12 in addition to the vehicle position data and the driving state data can also transfer image data.

The data is transmitted via a wireless data link 52, for example a cellular connection, to a server 40 having a receiving and transmitting unit 44 configured to receive and transmit data. - -

The server 40 also includes a recognition unit 46 to which the position and driving status data received from the receiving and transmitting unit 44 are transmitted.

The recognition unit 46 is configured to evaluate the position and driving status data transmitted to it in order to identify a potentially dangerous situation in traffic.

For example, if the evaluation of the transmitted position and driving condition data reveals that multiple vehicles 10 are performing sharp braking actions at approximately the same position, a hazard location 5 in that area is deduced. Likewise, from the stoppage of several vehicles 10 at positions where a stoppage of several vehicles 10 is not normally expected to be closed, for example on highways, to a traffic jam, for subsequent vehicles 10, 20, 30, 32 also a not inconsiderable danger point 5 represents.

If the recognition unit 46 has identified a danger point 5, this information is transmitted via the transmitting and receiving unit 44 and a data connection 54 to receiving units 22 installed in vehicles 20.

This data transmission 54 can likewise take place via a mobile radio network, but also via analog and / or digital radio transmitters. In a data transmission 54 via radio stations, the information can also be received by vehicles 20, which do not have access to a mobile network.

The receiving unit 22 is connected to one or more display devices 24, 25, 26, 28, 29, which are designed to be the driver of the received vehicle 20, but also drivers of other vehicles 30, 32, which are not formed with a suitable receiving unit 22, to warn in front of the danger spot 5 identified by the recognition unit 46.

Via a graphical display device 29, which is arranged for example in or on the dashboard of the vehicle 20, the information about the danger spot 5 can be displayed to the driver of the vehicle 30. A graphic display device 29 may also be arranged on the roof or behind the rear window of the vehicle 20 to be followed by vehicles - -

32, which themselves do not have a suitable receiving unit 22, to warn of the identified danger point 5.

Alternatively or additionally, the receiving unit 22 may also be connected to a hazard warning lights 25, brake lights 24 and / or the headlights 28 of the vehicle 20 to activate them when needed.

By activating the brake lights 24 in particular subsequent vehicles 32 can be warned of a danger point 5. By activating the headlights 28 (flashing light), oncoming and / or preceding vehicles 30 can be warned of a danger point 5.

In particularly critical situations, a horn (horn) 26 can be activated to give an audible warning.

In FIG. 1, the transmitting unit 12 and the sensors 14, 15, 16 connected thereto and the receiving unit 22 with the signaling devices 24, 25, 26, 28, 29 are shown in different vehicles 10, 20 for the purpose of clearer graphical representation. Of course, these devices are usually installed together in a vehicle 10, 20. Such a vehicle 10, 20 provides on the one hand necessary for the identification of danger spots 5 information; On the other hand, it receives the result of the evaluation of this information to warn the driver of the received vehicle 10, 20 as well as the drivers of other vehicles 30, 32, which are not equipped with corresponding receiving units 22, from danger spots 5.

In this case, the position sensor 14 can also be used to determine the information received from the receiving unit 22

Filter out information that is important for the received vehicle 20 and / or for the vehicles 30, 32 in its environment so that the drivers of these vehicles 20, 30, 32 are not distracted and / or bothered by warning messages that are not relevant to them.

FIG. 2 illustrates a schematic representation of a second exemplary embodiment that is configured without a central server 40. - -

In the second exemplary embodiment, the data transmission 50 takes place directly between the participating vehicles 10, 20.

The detection unit 46 for detecting dangerous situations is arranged in the sending and / or in the received vehicle 10, 20 in this case.

In the sending vehicle 10, the recognition unit 46 can be configured in particular so that only data on exceptional driving conditions are sent, in order to avoid that the data transmission 50 is burdened by irrelevant information. Moreover, it is also advantageous for reasons of data protection, if not continuously transmitted all position and driving condition data of the vehicle 10.

In the received vehicle 20, the recognition device 46 is designed, in particular, to identify possible danger spots 5 from the data received from one or more transmitting vehicles 10 and, in particular, to determine whether a danger spot 5 identified in this way is in the vicinity or on the driving route of the vehicle 20 is to (only) to activate the display devices 24, 25, 26, 28, 29, if so. As a result, the driver of the received vehicle 20 and the drivers of other vehicles 30, 32 in the vicinity of the received vehicle 20 are not confused and / or bothered by warning messages that are not relevant to them.
