Description

One aspect of the invention relates to a protective helmet, in particular for a driver of a motorized two-wheeler. Furthermore, one aspect of the invention relates to a system. Another aspect of the invention relates to a motorized two-wheeler.

Drivers of motorized two-wheelers usually have to exercise a very high level of attention in road traffic in order to be able to capture environmental conditions as well as possible and to be able to adapt their driving behavior accordingly. On the one hand, this results from the fact that the driver must wear a protective helmet when driving a motorized two-wheeler. With this, the field of vision is usually more restricted than, for example, in the case of a driver of a vehicle for whom such a protective helmet is not prescribed. Because of this protective helmet alone, the observation area and the perception of the surroundings are therefore more restricted for a driver of a motorized two-wheeler. In addition, it is also known that existing, conventional side mirrors are present which enable a two-wheeler to observe the side area and the rear area of the motorized two-wheeler, but only to a relatively limited extent. Furthermore, these conventional mirrors are exposed to vibrations of the two-wheeler, so that it is also known that, due to the vibrations of the mirrors, observation of the side area and the rear area of the motorized two-wheeler through a mirror can be difficult for the two-wheeler.

In addition, due to their single-track nature, it is common for motorized two-wheelers to drive or to drive on sections of the roadway only if the motorized two-wheeler is inclined. If conditions occur on these road sections that can impair driving safety, such motorized two-wheelers can fall or at least traffic situations in which driving safety is significantly reduced. This can be the case both because of dangerous road surfaces or because of animals that abruptly cross the road.

It is the object of the present invention to provide devices and systems in which the driving safety of a two-wheeler is increased.

This object is achieved by devices and systems according to the independent claims.

In particular, this object is achieved by a protective helmet, in particular a motorcycle helmet, a system, and a motorized two-wheeler.

An independent aspect of the invention relates to a protective helmet for a driver of a motorized two-wheeler. In particular, the protective helmet is a motorcycle helmet. In this context, the protective helmet has in particular a helmet shell. This helmet shell usually has a front cutout through which the helmet wearer can perceive the surroundings. The cutout can be designed as a completely bordered free space in the helmet shell.

In particular, the protective helmet also has a transparent cover for this section of the helmet shell. In particular, this cover is a visor. The visor is preferably movable, in particular foldable, arranged on the helmet shell. As a result, the cutout in the helmet shell can also be completely covered by this visor. The visor can be darkened depending on the amount of sunlight. It can have a sun visor. The sun blind can be a separate component. In particular, the function of the sun visor can also be integrated into the visor. For example, the visor can have switchable plastic glazing or a switchable film. There can also be a dimmable material in the visor. An electrochromic design is also possible. These exemplary embodiments are advantageous for the visual display of the at least one piece of information. Especially for the perceptibility in sunlight.

In particular, the protective helmet has at least one electronic communication device. This electronic communication device is designed in particular to output a roadway condition of a roadway acoustically and / or optically as information to the protective helmet wearer or for the protective helmet wearer. The electronic communication device, which is part of the protective helmet and is arranged on the protective helmet, is designed in particular so that this information can be perceived by the protective helmet wearer when he has put on the protective helmet. In particular, this output information is thus perceived by the protective helmet wearer when he has put on the protective helmet. Such a configuration of a protective helmet is particularly advantageous. This is because the helmet wearer can be reliably informed of critical road conditions on the road, especially when driving a motorized two-wheeler. In particular, lane sections of a lane that lie in front of the two-wheeler in the direction of travel of the motorized two-wheeler can thus be used by the driver of the motorized two-wheeler who is wearing the protective helmet, be communicated advantageously. In this way, safety-critical driving conditions with the motorized two-wheeler can be avoided in an improved manner. Particularly in the case of roadway sections that require the motorized two-wheeler to drive on in an inclined position, such critical roadway conditions can lead to safety-critical driving maneuvers and / or to the motorized two-wheeler falling. Therefore, a protective helmet of this type makes it possible in a particularly advantageous manner to inform the protective helmet wearer of such roadway conditions of a roadway section before driving on which represent dangerous spots when driving on, in particular when the motorized two-wheeler is in an inclined position. This protective helmet is particularly advantageous in that this information is perceived by a driver when the protective helmet is on. Acoustic and / or optical representations of this information in particular can be perceived very simply and intuitively by the driver in this regard. This is especially true when he is driving a motorized two-wheeler and should therefore also perceive the surroundings and other traffic. Road conditions are in particular road hazard conditions.

In particular, a road condition is a road surface condition. In particular, the condition of the pavement on the roadway is provided, in particular, as reference information. In another exemplary embodiment, however, a roadway condition can also be a roadway occupancy condition with an animal which is running or has run or can or will run on the roadway. So deer or animal change is also included. These are assignments that represent an obstacle that cannot be driven over, as is the case with a thin additional covering. A road condition information system is thus also provided as a further independent aspect of the invention. In particular, a road surface condition information system and / or an animal change information system. In particular, an animal change warning and / or detection system.

In particular, a roadway condition is an impaired roadway condition that has changed from an unaffected roadway condition. In particular, a road condition is thus meant which has an additional component compared to the road condition that is not impaired. In particular, an impairment zone is thereby formed on the roadway, in particular driving on a motorized two-wheeler, in particular in an inclined position.

In particular, the at least one piece of information or advisory information to be output is an optical and / or acoustic hazard warning that is created with a view to assessing a danger zone for driving in an inclined position with a motorized two-wheeler, in particular in a curve. The reference information can be categorized, in particular divided into at least one of at least two categories. It is designed differently depending on the category.

In one exemplary embodiment, the electronic communication device is designed to output the state of the roadway in real time while the protective helmet wearer is driving a motorized two-wheeler. This is a particularly advantageous embodiment, since it allows captured and / or received information to be output directly. The helmet wearer can also be informed immediately if such a lane section, which represents a relevant danger zone for driving the motorized two-wheeler, in particular the inclined position. This also makes it possible to know beforehand an existing hazard point in such a roadway condition and, if necessary, to be able to drive over it in an improved manner with an adapted driving behavior.

In one embodiment, the state of the roadway can be output optically as 2D information or as 3D information. It can therefore be output accordingly. In particular, the reference information can be a 2D image or a 3D image.

In one embodiment it is provided that the electronic communication device is designed to output the road condition of a road section which follows within a defined distance while the protective helmet wearer is driving a motorized two-wheeler in the direction of travel of the two-wheeler. In particular, this defined distance can be less than 500 meters, in particular less than or equal to 300 meters. The distance can be fixed. However, it can also be changeable as a function of ambient conditions and / or driving conditions of the motorized two-wheeler, in particular automatically changeable. Such a configuration makes it possible for the protective helmet wearer to be informed only if he is in a zone around this lane section with the lane condition to be reported. This avoids providing information about the most diverse and also distant road sections with dangerous road conditions. In particular, information about roadway conditions that is currently not important for the protective helmet wearer can thus be avoided. Information overload for the helmet wearer can thereby be avoided.

In particular, it is provided that the electronic communication device is designed to monitor the state of the roadway of a section of the roadway Output lane, which was determined during a trip of the hard hat wearer with a motorized two-wheeler in the lane of the roadway, which is also used by the motorized two-wheeler. Thus, for example, it can also be made possible that such information about a lane state of an opposing lane, on which the motorized two-wheeler is not moving or not moving, is not output. Through such targeted outputs with the electronic communication device that take into account the current situation of the motorized two-wheeler, in addition to the already mentioned information overload of the protective helmet wearer, the wearer of the helmet does not perceive the information that is actually important and essential for him in a concentrated manner.

In one embodiment it is provided that the electronic communication device has at least one optical detection unit. This optical detection unit is arranged directly on the safety helmet. The optical detection unit can for example have at least one camera and / or at least one night vision device and / or at least one lidar sensor or the like. A camera can be sensitive in the spectral range that is visible to humans. A camera can be sensitive in the infrared. So it can also be a thermal imaging camera. This can be very advantageous in particular for the detection of objects, such as animals, which are located to the side of the roadway and are covered. In this way, any critical driving situations due to animals can also be recognized at an early stage. For example, potential lane changes by such animals can then be recognized at an early stage. They can then be output as reference information. A camera can be a 3D camera.

In particular, this optical detection unit can be part of an animal change information system. The animal change information system can be arranged at least in part on the protective helmet. It can therefore also be part of the protective helmet. It is also possible in one embodiment that the protective helmet is part of the animal change information system. In particular if other components of the animal change information system are not arranged on the protective helmet. The same possibilities of exemplary embodiments as mentioned for the animal change information system can also be provided for the road condition information system. The animal change information system can be different from a road condition information system. However, an overall system can also be formed which has an animal change information system and a road condition information system, in particular a road surface condition information system. The animal change information system can also be part of the road condition information system. This can then have the animal change information system and a road surface condition information system. These respective systems are also to be viewed individually as independent aspects of the invention. The same applies to an inclined position information system, as will be explained below. In particular, all of the information systems mentioned are also designed, in particular, to determine the respective information.

The detection unit can be arranged on the helmet shell. For example, a carrier module for this at least one optical detection unit can be arranged on the outside of the helmet shell. In particular, this carrier module can be integrated into the outer shell of the helmet shell. However, the optical detection unit can also be designed as a removable module from the helmet shell. The optical detection unit can be arranged on the side of the helmet shell. However, it can also be arranged at the top of the helmet shell. It is also possible for an optical detection unit to be arranged in an inner padding of the helmet shell. In particular, the arrangement is then such that the detection area of the optical detection unit is oriented through the recess in the helmet shell, through which the protective helmet wearer also observes the surroundings.

A plurality of separate detection units, in particular optical detection units, which are designed to detect the roadway, can also be arranged on the protective helmet. You can capture in different directions. They can be of different selectivity.

This enables a protective helmet that can detect its surroundings itself. In particular, the state of the roadway can be determined on the basis of this information, which has been recorded by the detection unit of the protective helmet. In particular, this can be done with an evaluation unit. This evaluation unit can be part of the electronic communication device. The evaluation unit can thus also be part of the protective helmet and thus be arranged on or in the protective helmet. A protective helmet is thus provided which, in an advantageous exemplary embodiment, can detect the roadway itself. In particular, it is then also possible for the protective helmet itself to evaluate this recorded information with regard to a roadway condition of the roadway. Overall, this provides an intelligent protective helmet which enables precise information about a roadway condition of at least one roadway section of a roadway. Therefore, in such an exemplary embodiment, the protective helmet can not only correspond Output information about a roadway condition to a hard hat wearer, but record and / or assess it independently.

In one exemplary embodiment, the electronic communication device has an acoustic output unit with which information on road conditions can be output acoustically and / or has an optical output unit with which information on road conditions can be output optically.

However, it is also possible for the protective helmet to have a receiving unit. This receiving unit can be part of the electronic communication device. The receiving unit is designed in particular for the wireless reception of signals. For example, it is then also possible for information about a roadway condition of a roadway to be transmitted externally to the protective helmet and received by the receiving unit. For example, such signals can be received by a central communication unit which is arranged externally to the protective helmet. This communication unit can be part of a communication system, in particular a two-wheeler communication system. In this way, information of this type about roadway conditions can be exchanged via this communication system. In this way, other motorized two-wheelers can also be informed about the condition of the lane that they are not currently driving on or from which they are still further away and cannot currently record with their own detection units.

It is also possible for this communication unit external to the protective helmet to be arranged in that motorized two-wheeler with which the protective helmet wearer wearing the above-mentioned protective helmet is currently driving.

It is also possible for such a communication unit to be arranged in another vehicle with which the protective helmet wearer is not currently driving. This can be another motorized two-wheeler, for example. However, it is also possible that this other vehicle is not just a single-track two-wheeled vehicle, but is, for example, a multi-track vehicle. For example, this can be a passenger car or a truck.

In one embodiment it is provided that information about a roadway condition is outputted in which a roadway condition is an impaired roadway condition that reduces the driving safety of a two-wheeler compared to an unimpaired basic roadway condition. In particular, this adverse road condition is one that impairs driving with a motorized two-wheeler, in particular in a curve and / or in particular when the motorized two-wheeler is inclined, compared to the basic road condition. This means in particular that this adverse road condition increases the risk of the motorized two-wheeler falling, in particular when driving at an incline, compared to the basic road condition. The pertinent roadway condition is, however, also to be understood as one that can and may be run over with the motorized two-wheeler.

In one embodiment it is provided that a roadway condition is one in which a base pavement of the roadway, which is intended as intended and defines the roadway as such, has a local change that reduces friction. This local change can be formed permanently in the base covering. For example, this can be a material removal. In this regard, larger grooves or furrows or roughening can be viewed as such a friction-reducing change. Bitumen fillings that are formed in the base pavement and fill cracks or the like can also be viewed as such changes that are permanently formed in the base pavement. In particular, damp or wet bitumen fillings in this regard are to be regarded as such changes. In particular, dry bitumen fillings are not to be regarded as such changes. In one exemplary embodiment, it is therefore possible for a material that is additionally present on the roadway and that is different from the base covering to be viewed as a change. In particular, such an additional material can also be referred to as a change or not, depending on the moisture condition that it exhibits. This also means that the electronic communication device and / or a lane condition information system can individually assess such additional material as a function of weather conditions, in particular assess it as a critical change in the above-mentioned sense.

In a further exemplary embodiment it can be provided that a change which reduces the friction on the base covering is a temporary change. For example, such a change can occur as an additional layer on the base covering. In particular, such an additional coating can be an oil coating or an oil film. Such an additional covering can also be sand or gravel or leaves. A local ice formation or a local snow layer can also be such an additional layer. In particular, such an additional support has a maximum height of ten centimeters, in particular, a maximum height of five centimeters. In addition to the above-mentioned and usually very thin additional layers close to the floor, lost components, such as craftsmen's objects, such as boards or tools or the like, can thus also be understood as such changes to the base covering. The base surface can be, for example, tar or concrete, which is common for roadways.

Preferably, it is generally also possible that different changes in the state of the road are prioritized and / or categorized differently with regard to their potential danger for driving over with a motorized two-wheeler, in particular in an inclined position. This can be done by the communication device or by the road condition information system itself. For example, this can be dependent on the type of change (e.g. oil, sand, gravel, wet leaves, etc.) and / or depending on the size (e.g. large area or small area, line or spot, length and width, etc.) the change and / or depending on the position (e.g. at the edge of the road or only in the middle or across the entire width of the lane, etc.) the change on the roadway and / or depending on the orientation (e.g. across the roadway, along the roadway, inclined to the roadway etc.) of the change in relation to the course or the direction of the roadway. This prioritization can also be carried out automatically by the communication device depending on the current weather (wet or dry or shadows cast on the impairment zone, etc.). For example, a thin bitumen line in the dry state is less critical than a wet bitumen line. A bitumen line running transversely to the roadway is also less critical than a longitudinal or inclined bitumen line. This can also be done for the other changes, such as oil, sand, gravel, etc.

A priority list can also be configured by a user himself.

In one exemplary embodiment, it is possible that a type of at least one piece of information about the roadway condition and / or the number of pieces of information about a roadway condition and / or the outputting or non-outputting of the information takes place as a function of at least one decision criterion. A decision criterion can be a parameter that characterizes the environment, such as the weather and / or the course of the roadway and / or the distance between the current position of the motorized two-wheeler and the impairment zone of the roadway. In addition to or instead of this, it can be a parameter that characterizes the motorized two-wheeler. In particular, this can be at least one parameter that represents the current driving state of the motorized two-wheeler and / or represents an expected future driving state of the motorized two-wheeler. The driving condition to be expected in the future can be that which is expected in the impairment zone at which the road condition occurs. This can be estimated, for example, by the communication device or the system. For example, depending on the course of the roadway, in particular before and / or on and / or after the impairment zone, and / or depending on the current speed and / or the expected speed of the motorized two-wheeler at the impairment zone, and / or the current lean angle of the motorized two-wheeler and / or the expected incline of the motorized two-wheeler, in particular in the impairment zone. Especially the inclined position at the impairment zone or the lane section with the road condition or the road hazard condition.

In an advantageous embodiment, it is provided that the electronic communication device of the protective helmet has at least one head-up display and / or a head-mounted display (HMD), that is to say an “output attached to the head”. This is a particularly advantageous embodiment, since it enables a very precise visual representation of the information about the roadway condition that is easy and intuitive for the protective helmet wearer to perceive. In the case of a head-up display, the information on the state of the road is projected as a virtual image projection into the field of vision of the helmet wearer. In particular, the visor of the protective helmet can serve as a display unit for this virtual image projection, for example. The head-up display can in particular be arranged in the helmet shell of the protective helmet. In particular, when the protective helmet wearer has closed the visor of the protective helmet, such use of the visor as a display unit for this head-up display is advantageous. The head-up display can be designed to carry out the image projection in a specific location area on the display unit. For example, on the left side of the visor or right side of the visor or in the middle of the visor and there in an upper area. This is also possible with a cockpit cladding of the motorized two-wheeler. In this way, locally assigned displays can be made in relation to the local occurrence of the information in the vicinity of the motorized two-wheeler. In particular, at least two head-up displays can also be provided, which project an image into different areas, as mentioned above. A cockpit fairing can also be a raised windshield.

With regard to a head-mounted display, this can be arranged on the protective helmet in such a way that the optical information is perceived by the helmet wearer. In particular, it is projected onto the retina of an eye of the protective helmet wearer. In particular, the arrangement is such that the field of vision of the protective helmet wearer is not restricted with regard to the direct perception of the surroundings. however, it can also be provided that the protective helmet wearer does not perceive the surroundings directly but rather on the display unit of the head-mounted display. For example, these can be camera recordings of the surroundings.

The head-mounted display can project images either on a screen close to the eye or directly onto the retina. A virtual retinal display can also be provided. A virtual retinal display is a display technology that creates a raster image directly on the retina of the eye. The user gets the impression of a canvas floating in front of him. The virtual retinal display can also be referred to as a light field display. A head-mounted display can, for example, also be a helmet-mounted display system (helmet-mounted display system).

The head-up display can be designed as a microsystem, at least in some components. For example, the head-up display can have micro-optics. This is particularly advantageous when installing it on the protective helmet. Especially in terms of weight and space requirements.

In addition to or instead of this, however, it can also be provided that a display unit, which optically outputs the information about, in particular, the state of the roadway, is an OLED film. This can for example be attached to the visor. This display unit can be part of the electronic communication device of the protective helmet. This film can be connected to and / or communicate with a control unit of the communication device, so that the corresponding signals for image display can be transmitted on the film.

However, it is also possible that the electronic communication device has at least one laser. This can be arranged on the protective helmet in such a way that the information about the state of the roadway is generated optically and can be perceived by the protective helmet wearer when the protective helmet is on. For example, the laser can project the information optically onto an area of the road. It is also possible for this laser to generate the information as a hologram, for example.

Another independent aspect of the invention relates to a motorcyclist's protective helmet with a helmet shell and a head-up display and / or a head-mounted display, so that a wide variety of information can be visually perceptible to the protective helmet wearer when the protective helmet is on. This can, for example, also be information on a roadway condition of a roadway.

In one embodiment it is provided that the communication device is designed to acoustically and / or optically output a local impairment zone characterizing the roadway condition of a roadway as information to a protective helmet wearer. Such a local driving safety impairment zone can thus be presented in an acoustically perceptible and / or optically recognizable manner. This is also the case, in particular, when the protective helmet wearer has put on the protective helmet. This driving safety impairment zone is, in particular, that lane section of the lane on which an impairment, in particular due to a change described, has occurred, as was explained above by way of example.

In one embodiment it is provided that the electronic communication device is designed to output the size and / or the position on the roadway of this impairment zone as information to the helmet wearer acoustically and / or optically. This significantly increases the precision of the information presentation. The helmet wearer who perceives the information can quickly get a more precise picture of the type of impairment zone. In particular, it is then possible in this context to adapt very quickly to the driving behavior with the motorized two-wheeler. In addition, he can also use it to prepare emotionally for the impending drive on this section of the road. Being surprised and thereby possibly abrupt incorrect driving behavior, which could then occur by the driver of the motorized two-wheeler, can thus also be avoided in an improved manner.

With this design of the protective helmet, the two-wheeler can adjust to the upcoming situation and prepare better.

In one embodiment it is provided that the electronic communication device is designed to output the advisory information at a speed of the motorized two-wheeler greater than or equal to 25 km / h, in particular greater than or equal to 30 km / h. The output therefore only takes place from this speed.

In one embodiment it is provided that the electronic communication device is designed for communication with a unit external to the protective helmet. In particular, wireless communication can be provided here. the Communication is made possible to the effect that detected information about a roadway condition of a roadway can be transmitted, in particular automatically, to the helmet-external unit and / or the information can be obtained from the safety helmet-external unit from the safety helmet. This helmet-external unit can be, for example, the helmet-external communication unit already mentioned above.

This is a further, very advantageous embodiment, since a critical road condition can thus be indicated even earlier if necessary. The protective helmet itself and / or the motorized two-wheeler with which the protective helmet wearer is traveling no longer has to detect such a roadway condition of a roadway itself, but can, if necessary, access information from other road users that has been recorded and evaluated in this regard, in particular other two-wheeled drivers or other vehicle drivers. This further improves the driving safety in this regard when driving a motorized two-wheeler, in particular when driving the motorized two-wheeler on curves and / or in an inclined position.

In one embodiment it is provided that information on curve radii of a curve and / or on curve lengths of a curve and / or on curve inclinations of a curve and / or non-transparent curves behind crests can be output as information to the helmet wearer as the road condition. In this way, in particular, geometric information about the roadway sections is also transmitted. These, too, can lead to safety-critical driving conditions with the motorized two-wheeler, for example in the case of very tight bends or curves hanging outwards.

In one embodiment, it is provided that the information about the state of the roadway is determined and / or output as a function of a GNSS position of the motorized two-wheeler with which the protective helmet wearer of the protective helmet is traveling. In particular, it is also possible in this context for the protective helmet to have a position determination unit. In particular, this can be used to determine a global position of the protective helmet. For example, this can be done on the basis of a GNSS signal. In addition to or instead of this, however, a landmark-based self-localization of the protective helmet can also take place. This can be done on the basis of information about the surroundings that is provided with at least one optical detection unit of the protective helmet and / or of the motorized two-wheeler with which the protective helmet wearer is traveling. Depending on such a global position of the protective helmet and / or of the motorized two-wheeler, information on a roadway condition of a roadway can then be output. This also enables a local coupling between the current position of the protective helmet and the roadway with the critical roadway condition. This also enables very specific acoustic and / or optical information to be sent to the protective helmet wearer without overloading them with unnecessary information. The information is output acoustically and / or optically only if, due to the position of the protective helmet and / or the motorized two-wheeler, the critical road condition is or could become of interest for the further route.

For example, a navigation route along which the motorized two-wheeler is traveling can also be taken into account in this context. This is particularly advantageous if the motorized two-wheeler has a navigation device and a relevant navigation route has been selected.

In one embodiment it is provided that the electronic communication device of the protective helmet is designed to output a travel trajectory for the motorized two-wheeler acoustically and / or optically as a function of the information on the state of the roadway. This can in particular be a driving trajectory with which the road section with the critical road condition can be driven over directly. However, it can also be a travel trajectory that indicates that this section of the road is to be bypassed. In this context, driving around means, in particular, a trajectory which, for example, in the lane, leads relatively close to the impairment zone that has the critical roadway condition. The driving trajectory can be output as 2D information or as 3D information. This can also be done here optionally. In particular, this can be set by a user or a decision can be made automatically as a function of a driving condition parameter of the motorized two-wheeler and / or a road condition. In the case of a 3D representation, a tilted image of the motorized two-wheeler can thus also be displayed. In particular, the motorized two-wheeler can also be shown as an avatar.

In one embodiment it is provided that the electronic communication device of the protective helmet is designed to generate optical information as augmented reality output and to output it accordingly. This enables a particularly realistic representation scenario for the protective helmet wearer. It is then also possible for the visual representation of this roadway state to take place precisely at the point at which the protective helmet wearer perceives the surroundings. He therefore knows exactly where in the lane area this impairment zone is in front of him lies. It is also possible to generate a 3D output in addition to or instead of this.

In an advantageous exemplary embodiment, it is provided that the electronic communication device is designed to dynamically adapt an optical information output to the head inclination of the protective helmet wearer relative to the roadway. This means that the optical information display of the state of the road is carried out taking into account the current head inclination of the hard hat wearer wearing the hard hat. As a result, in advantageous exemplary embodiments, a visual presentation for the protective helmet wearer can always take place, which he can intuitively perceive easily and can also understand accordingly quickly. This can in particular also be advantageous when an augmented reality output and / or a 3D output takes place.

In an advantageous embodiment, the electronic communication device has at least one microphone. This is arranged in such a way that a protective helmet wearer can emit a voice signal when the protective helmet is on, which can be evaluated by the communication device. This also makes it possible for the protective helmet wearer to generate information relating to the condition of the roadway himself. In addition to or instead of this, the protective helmet wearer can then also compose additional information by means of a voice signal. As a result, the understanding of the state of the road can be improved if necessary. In particular, this exemplary embodiment is advantageous if a communication system is provided in which several protective helmet wearers are to be informed about roadway conditions. In this way, for example, a protective helmet wearer who is currently driving or has been driving on a lane section with a critical lane section in this regard can provide corresponding information to this communication system, in particular by means of voice signals. These can then be partially or completely provided by the communication system to other motorized two-wheeled riders, in particular transmitted to two-wheeled riders who have a protective helmet according to the above-mentioned aspect or an advantageous embodiment thereof. In particular, the system can also be trained in this way. Because it can compare its own assessments with the speech signals. The microphone can be arranged, for example, in a chin guard part of the helmet shell.

It is also possible that this electronic communication device can be activated automatically for recording voice signals. For example, the helmet wearer can initiate this with a specific start signal. The start signal can take the form of a voice signal, for example. However, this can also be done, for example, by actuating an operating element on the protective helmet. Such an activation is also possible by actuating an operating element on the motorized two-wheeler, if in particular a communication option is formed between a communication unit of the motorized two-wheeler and the protective helmet wearer traveling with it and wearing the mentioned protective helmet.

In this context, it is also possible for an above-mentioned position determination unit, which can be part of the protective helmet, to be activated permanently. This position determination unit can, however, also be deactivated and activated, for example, by the protective helmet wearer. The protective helmet wearer can thus determine for himself when such a global position of the protective helmet is determined. For example, such activation can take place with a voice signal from the helmet wearer. It is also possible for the position-determining unit of the protective helmet to be activated in this way by actuating an operating element on the protective helmet. It is also possible here that an operating element on the motorized two-wheeler, with which the protective helmet wearer is currently traveling, is operated. In this way, the position-determining unit in the protective helmet can then be activated, in particular by wireless communication. In this context, it is also possible, in addition to or instead of this, for a position determination unit of the motorized two-wheeler, which is arranged outside the protective helmet, to be activated. This then determines the current global position of the motorized two-wheeler. This position, which also corresponds to that of the protective helmet, can then be transferred to the protective helmet. In a particularly advantageous manner, this association between the global position of the protective helmet and / or the motorized two-wheeler and the critical roadway condition enables a particularly precise determination of the position of the roadway section with the critical roadway condition. In this way, it is particularly advantageous not only to transmit a critical roadway condition of the roadway section to other protective helmet wearers and / or motorized two-wheelers, but also a very exact global position of such a roadway section. In particular, the position determination unit of the protective helmet can also be activated permanently. In particular, the position determination unit of the motorized two-wheeler can also be activated permanently.

In a further exemplary embodiment, it is provided that the electronic communication device is additionally designed to output a roadway state of a roadway or instead of this also to the effect of a Output inclination information of the motorized two-wheeler acoustically and / or optically. In this context, it can be provided that the motorized two-wheeler with which the protective helmet is traveling with its protective helmet has an inclined position information unit or an inclined position information system. This can be designed to output lean position information of the motorized two-wheeler acoustically and / or optically. However, it can also be provided that this inclined position information system is also designed to determine the inclined position of the motorized two-wheeler itself. In this regard, the banking system can have one or more sensors. In particular, these can determine a lean angle of the motorized two-wheeler. For example, this lean angle is an angle between a vertical and the vertical axis of the motorized two-wheeler. For example, 3D sensors and / or a gyroscope and / or further sensors can be provided here, by means of which such inclined position information can be determined. In particular, current banking information can be determined and output in this context when driving the motorized two-wheeler. In particular, the electronic communication device of the protective helmet is designed to output a numerical value relating to an angle of inclination as inclined position information. In addition to or instead of this, this angle value can also be output optically. For example, by means of the above-mentioned head-up display in the protective helmet. It is also possible in addition to or instead of this that an optical output is also carried out graphically. For this purpose, an artificial horizon can also be displayed here, for example. The current incline of the motorized two-wheeler can then be displayed in this. This, too, can be designed in such a way that when the protective helmet is on, the protective helmet wearer visually perceives this information.

Here, too, in an advantageous exemplary embodiment, an augmented reality output and / or a 3D output can take place with regard to this inclined position information. Especially in an artificial horizon.

In an advantageous embodiment it is provided that the protective helmet wearer can activate and deactivate the electronic communication device. It is also possible that at least partial functions, as they can be individually explained and present in the advantageous exemplary embodiments above, can be activated and deactivated. This enables the protective helmet wearer to configure the electronic communication device of his protective helmet individually and to adapt it dynamically in the context. Information overload can thus be avoided. In particular, such a user-specific configuration also provides a wide range of setting options.

This means that every helmet wearer can configure the electronic communication device of the protective helmet the way they want it. A very user-specific acoustic and optical information display is achieved. Road conditions that a very experienced driver can easily master, for example, cannot then be output because they may not be critical for this driver.

In particular, an independent aspect of the invention also relates to a protective helmet, in particular a motorcycle helmet, with at least one electronic communication device, the communication device being designed to acoustically and / or optically output information about the inclination of a motorized two-wheeler. In particular, to output inclined position information about the motorized two-wheeler with which the protective helmet wearer is currently traveling. In particular, current information on the inclined position of the motorized two-wheeler can be provided in this context. In addition, this protective helmet can then also be designed in such a way that with this electronic communication device or another electronic communication device of the protective helmet a roadway condition of a roadway can be output acoustically and / or optically as information to the protective helmet wearer.

Generally speaking, the electronic communication device can have at least one receiving unit and / or at least one transmitting unit. It can preferably have at least one processing unit, in particular an evaluation unit, for example a microprocessor. The electronic communication device preferably also has a memory unit. The electronic communication device has in particular at least one wireless communication interface. This can also have a Bluetooth interface, for example. In addition, there can also be a communication interface that can receive satellite signals. The electronic communication device can also have a wireless communication interface, by means of which wireless communication with other vehicles is made possible.

In this regard, communication with other protective helmets, which is designed in accordance with the above-mentioned aspect or advantageous embodiments thereof, can also be made possible directly.

This also makes it possible, for example, for two two-wheelers, each wearing their protective helmet, to be able to connect directly to one another or to communicate with one another by means of voice signals.

The communication device can be a unit or have a plurality of units. It can be a unit device. The communication device can also be a system. It can also have several separate systems. These can have different functions. In particular, the systems can also work together. An overall system can be formed.

Another independent aspect of the invention relates to a communication system with a protective helmet according to the above aspect or an advantageous embodiment thereof. In addition, the communication system has at least one communication unit external to the protective helmet. In particular, the external communication unit is designed for wireless communication with the protective helmet. In this context, the communication system preferably has at least one wireless communication interface, by means of which wireless communication between the protective helmet and the external communication unit is enabled. The communication unit can be such as has already been explained above in advantageous exemplary embodiments. In terms of location, it can also be arranged at corresponding, exemplary positions.

Another independent aspect of the invention relates to a two-wheeled communication system, in particular a motorcyclist communication system. This motorcyclist communication system has at least one communication unit, which has for communication with several protective helmets according to the above-mentioned aspect or an advantageous embodiment thereof. In particular, this motorcyclist communication system has at least one protective helmet according to the above-mentioned aspect or an advantageous embodiment thereof. This enables information to be provided for several motorized two-wheelers. In particular, information about road conditions and / or about inclined position information can thus be transmitted to at least several protective helmets and / or to at least several motorized two-wheelers and exchanged in this regard.

By means of this motorcyclist communication system, a direct exchange of correspondingly named information between motorized two-wheelers can be made possible. It is also possible that several protective helmets configured in this way, as explained above, can communicate at least temporarily at the same time with at least one communication unit of the communication system.

This also makes it possible for the motorized two-wheeler drivers to be able to obtain corresponding information individually from this communication system or this motorcyclist communication system. For example, these can be accessed individually for each user. It is also possible for this communication system to have an automatic module. If corresponding information about a roadway condition and / or inclined position information occurs, this automatic module can be used for automatic transmission to another protective helmet and / or to another motorized two-wheeler. In particular, this can take place automatically as a function of the position of the other protective helmet and / or of the other motorized two-wheeler, in particular as a function of the global position of this protective helmet compared to the global position of the critical roadway condition of a roadway section.

It is also possible that a protective helmet only receives information from this automatic module that information that may be of interest may be available. If the information retrieval is not desired or is not initiated by the two-wheeler, there is no further automatic transmission of information to the protective helmet and / or to the motorized two-wheeler.

In an advantageous embodiment, this electronic communication system has a search module. This search module can be used to search for motorized two-wheelers and / or protective helmets that are located in a predetermined surrounding zone around this position of the lane section, depending on the information available about a roadway condition of a roadway, in particular also the position of this roadway condition of the roadway. It is thus possible to automatically search for such motorized two-wheelers and / or appropriately designed protective helmets in a targeted manner. A targeted transmission of information to such positionally assigned protective helmets and / or motorized two-wheelers is then made possible. For example, such a search can be carried out using a GNSS module.

In an advantageous exemplary embodiment, the electronic communication device can also be designed, for example, as a retrofit device, in particular for an existing protective helmet. It is thus easily possible to retrofit protective helmets with such an electronic communication device.

Furthermore, it is possible that the above-mentioned evaluation scenarios and / or output scenarios and / or configuration scenarios are enabled on the basis of a software electronic likation. Such a software application can, for example, also be downloaded to a portable mobile radio terminal. In particular on a mobile radio terminal of the helmet wearer. It is thus also possible for such a communication terminal, such as a tablet or a smartphone, for example, to be able to couple and communicate in particular with the communication system mentioned above.

Another independent aspect of the invention relates to an electronic road condition information system. The lane condition information system is in particular for recognizing at least one dangerous lane condition which, in particular when a motorized two-wheeler is driven over directly and in an inclined position, potentially impairs the driving safety of this motorized two-wheeler. In addition to or instead of this, the road condition information system is designed to output information on at least one dangerous road condition that potentially affects the safety of a motorized two-wheeler, especially when a motorized two-wheeler is driven over directly and in an inclined position. In particular, this electronic road condition information system has a protective helmet for a driver of the motorized two-wheeler. In particular, this electronic road condition information system has an electronic communication device. This electronic communication device is designed in particular to output the advisory information acoustically and / or optically in such a way that it is perceived by the driver who has put on the protective helmet. The communication device has, in particular, an output unit for outputting the advisory information. The output unit is arranged in particular in the protective helmet.

Another independent aspect of the invention also relates to a motorized two-wheeler with at least one electronic communication device, as was set out above for the protective helmet or an advantageous embodiment thereof. The communication device can therefore also be arranged in a two-wheeler. It then does not have to be arranged in the protective helmet. In particular, however, in one embodiment it is also possible for a communication device to be arranged in the protective helmet and a communication device in the motorized two-wheeler, with which a driver wearing the protective helmet drives. The at least two communication devices can then be operated independently of one another. However, they can also be operated together and be part of a communication system.

Another independent aspect of the invention also relates to a motorized two-wheeler with at least one electronic road condition information system. These above-mentioned exemplary embodiments can also be provided with regard to the road condition information system.

In particular, the electronic road condition information system is designed with at least one electronic communication device, as was already mentioned above in connection with the design of the protective helmet. The electronic communication device, in particular also with these advantageous exemplary embodiments mentioned above, can preferably also be part of this electronic road condition information system. In particular, the electronic communication device can also be arranged externally to the protective helmet in this context. In particular, however, if it is part of the electronic road condition information system, it can also be part of the protective helmet.

It is also possible that in this motorized two-wheeler with a related electronic road condition information system, the acoustic and / or optical output of this information about the road condition of the road is carried out on an output unit of the motorized two-wheeler. Thus, in a related embodiment, the output can also take place independently and separately from the protective helmet.

In general, it is also possible for the protective helmet to have at least one detection unit, in particular at least one optical detection unit. This can also be oriented in such a way that it detects to the side and / or to the rear. It is thus also possible for the protective helmet to have an electronic rear-view mirror in an advantageous exemplary embodiment. In particular, a blind spot assistant can also be integrated in the protective helmet in this context. This example of a protective helmet with an electronic rearview mirror and / or an electronic blind spot assistant can also be an independent aspect of the invention.

An independent aspect of the invention relates to a protective helmet, in particular a motorcycle helmet, with a helmet shell and a viewing window in the helmet shell, through which a protective helmet wearer can look into the surroundings when the protective helmet is on, the protective helmet having at least one rear view camera, which is arranged on the protective helmet, that their detection area, at least in some areas, at least one The blind spot area is recorded which cannot be seen by the helmet wearer when looking through the viewing window.

Additionally or alternatively, it can be provided that a motorized two-wheeler has an optical detection unit. This at least one optical detection unit is oriented in such a way that its detection area is oriented to the side and / or to the rear. The motorized two-wheeler can thus be designed with an electronic rear-view mirror. Conventional side mirrors or rear-view mirrors are then no longer required. In particular, such an optical detection unit can also be part of a blind spot assistant of the motorized two-wheeler. In particular, this information can be displayed on a display unit of the motorized two-wheeler in an optical detection unit arranged and oriented in this way. In addition to or instead of this, however, they can also be displayed, for example, on an optical display unit of the protective helmet itself. For example, they can be displayed by a head-up display of the protective helmet and / or by a head-up display of the motorized two-wheeler. The head-up display can also be designed here as an augmented reality head-up display. However, it is also possible to design the display unit as an OLED film.

For example, at least one OLED film can be arranged on a visor of the protective helmet or on a transparent cockpit lining of the motorized two-wheeler. An OLED film can be arranged on a left-hand and / or on a right-hand end region of the visor. Likewise, an OLED film can be arranged on a left-hand and / or on a right-hand edge region of the cockpit lining. This means that locally assigned information from the surroundings of the motorized two-wheeler can also be displayed. For example, if information about the surroundings is available or occurs on the right or left of the motorized two-wheeler. For example, when information from an electronic rear-view mirror is displayed through the OLED film. For example, when information from an animal change information system is displayed through the OLED foils. For example, if an animal potentially crossing the road is on the left of the road or on the right of the road. In particular, if the animal cannot yet be recognized directly by the driver and / or for an early warning, this is advantageous.

The OLED foils can be activated for visual display. For example, by a driver himself. In particular, this can be done by actuating an operating element on the motorized two-wheeler. For example, this control element can be on a handle of the handlebars of the motorized two-wheeler. This allows operation without letting go of the handle. Safe driving is thereby also made possible when actuated. As a result, the information of an electronic rearview mirror can in particular also be displayed individually depending on a display request or a display requirement of the driver. Since the image projection with the head-up display or the position of an OLED film takes place especially in a driver's field of vision, the driver no longer has to turn his head in order to look into the mirror, as is the case with conventional side mirrors, but can instead Leave the head essentially unchanged. He can therefore continue to look ahead and also recognize the display of the electronic rear-view mirror, which in particular has an integrated blind spot assistant. It is also possible for the display to be activated with the head-up display or on the OLED film, depending on the direction in which the driver is looking. If this person directs his gaze to the image projection area or the area where the OLED film is arranged, this can be recognized, for example, with an eye tracking system, which is arranged in particular in the protective helmet or on the motorized two-wheeler, and the display is automatically activated will. If we then turn our eyes away again, there is an automatic deactivation. It is also possible for the display to remain activated for a predefined period of time after activation. For example, with the function of an electronic rear-view mirror, this can be up to 5 seconds or up to 10 seconds. In the case of the function of a head-up display, in particular for the display of lane conditions and / or animal changes, this can also be longer, in particular until the danger point has been passed.

Provision can be made for a plurality of separate optical detection units to be arranged on the protective helmet itself in order to implement an electronic rearview mirror in the protective helmet. It is also possible for several optical detection units to be arranged directly on the motorized two-wheeler in order to be able to implement such an electronic rearview mirror and / or a blind spot assistant.

For example, generally, and not only to implement an electronic rearview mirror and / or a blind spot assistant or also independently thereof, it can also be provided that an optical detection unit, in particular a camera, is arranged on the motorized two-wheeler, the detection area of which is oriented towards the front . At least one further optical detection unit, in particular a camera, can be arranged on the motorized two-wheeler in such a way that it covers the rear area behind the motorized two-wheeler Two-wheeler captured. In addition, an optical detection unit can also be provided, the detection area of which is oriented towards the left. In addition, a further optical detection unit can be provided which can detect the right lateral area surrounding the motorized two-wheeler. The optical detection units can be arranged, for example, on direction indicators and / or on a rear light and / or on a headlight of the motorized two-wheeler. Positioning on a suspension fork of the front wheel of the motorized two-wheeler can also be provided. It is also possible to attach an optical detection unit in the area of a holder for a license plate. Other positions in addition to or instead of these can also be provided on the two-wheeler.

If a motorized two-wheeler has a cockpit covering, which is usually transparent, this cockpit covering can also be used as a display area for a virtual image projection, as is the case with a head-up display.

It is then also possible to change the virtual image projection. This means that the virtual image projection can switch between the display in the area of a visor of the protective helmet and in the area of this cockpit cladding of the motorized two-wheeler. In particular, a user of the motorized two-wheeler and the protective helmet can change individually in this regard. For example, this can be done by actuating an operating element. However, this is also possible, for example, by means of a voice signal.

Another independent aspect of the invention is based on the fact that a motorized two-wheeler has in particular an activation button or an operating element and / or a voice system with which the global position of the motorized two-wheeler, in particular a GNSS position determination, can be activated. This can be done individually by the two-wheeler. As a result, when driving, the driver can activate a hazard detection system, in particular an electronic road condition information system, and the global position in this regard, in particular the current global position, can be determined automatically for this purpose. This automatically enables a link between the current global position of the motorized two-wheeler and the hazard or the critical roadway condition of a section of the roadway.

In an advantageous embodiment it is provided that at least one optical detection unit, which is arranged on the protective helmet and / or on the motorized two-wheeler, can be moved individually. This can be done automatically. For example, the position of such an optical detection unit can be determined in the world coordinate system and thus also be a global position here. It can preferably always be positioned in such a way that it has and maintains certain coordinate parameters. This can then take place independently of the current inclined position of the motorized two-wheeler and / or the inclination of the head of the helmet wearer. In addition to or instead of this, an optical detection unit can also be arranged on the protective helmet and / or on the motorized two-wheeler in a vibration-damped manner.

In particular, an optical detection unit can have an image stabilizer. As a result, the optically recorded information can be recorded more precisely and evaluated in an improved manner.

Another independent aspect of the invention relates to an electronic vehicle dynamics control system for a motorized two-wheeler. Depending on information in particular from a communication system, as mentioned above, and / or an electronic road condition information system, as mentioned above, and / or depending on an incline determination system, as mentioned above, and / or an animal change information system, as mentioned above and / or an electronic rearview mirror, as mentioned above, the driving behavior of the motorized two-wheeler can be changed. In particular, the electronic vehicle dynamics control system can automatically intervene in the driving behavior of the motorized two-wheeler. In particular, this can take place automatically if, depending on an evaluation of the information received from at least one of the systems mentioned with the current driving state of the motorized two-wheeler, a situation is recognized by the driving dynamics control system, so that a critical driving state of the motorized two-wheeler occurs or is highly likely will.

The electronic communication device 7th can also at least one evaluation unit 11th exhibit. This evaluation unit 11th can on the hard hat 1 , especially the helmet shell 2 , be installed. With this evaluation unit 11th information relating to road conditions can be evaluated. This can therefore be done directly on the safety helmet 1 take place.

In one embodiment, the electronic communication device 7th at least one acoustic output unit 12th on. This is preferably an acoustic output unit 12th on the hard hat 1 , especially on the helmet shell 2 , installed. In particular, it is installed in the area on which an ear of a protective helmet wearer is arranged. This acoustic output unit 12th can for example in the upholstery 4th be built in. By means of this acoustic output unit 12th information on road conditions can be output acoustically. In particular, this information becomes road conditions with this acoustic output unit 12th issued.

As already explained above, a road condition is in particular one which is an impaired road condition that reduces the driving safety of a motorized two-wheeler compared to an unimpaired basic road condition. A road condition is in particular a road surface condition. A roadway condition is in particular one in which a base pavement of the roadway exhibits a change that reduces the coefficient of friction. The local change can be temporary. However, the local change can also be permanent. If the local change is permanent in the base layer, the base layer can be tar or concrete, for example. Such a permanent change in the base pavement of the roadway itself can, for example, be material removal. For example, grooves or millings or tears or furrows or roughening can be provided here. Bitumen fillings that are formed in the base layer can also be such permanent changes to the base layer. Changes that temporarily reduce the coefficient of friction of a base surface on the roadway are, in particular, additional surfaces or additional conditions on this base surface. Such additional conditions are, in particular, materially different from the base covering. Such an additional covering can be, for example, an oil covering or a sand covering or a gravel covering or leaves or the like. Such additional coverings can be user-related changes. This means that such specific additional coatings were created by lost cargo or defective functional units of a vehicle. However, it is also possible that such temporary changes have also occurred, for example, as a result of flooding onto the roadway, for example in the event of heavy rainfall or the like. Drifts by wind or the like can also bring about such temporary changes with an additional covering on the base covering. A temporary change with an additional covering can, however, also be another loss of cargo. For example, this can also be a board or a tool or the like.

Changes caused by nature that represent an additional layer of the base layer can be, for example, local ice or local snow or local leaves or branches. With a local presence of the change it is to be understood in particular that this change occurs only zonally on the roadway. For example, as a patch or line.

These examples of additional coverings, which represent roadway hazard conditions for a motorized two-wheeler, in particular when driving past or driving over in an inclined position, can now be worn by a wearer of the protective helmet 1 be output or displayed acoustically and / or visually. In this way, in an advantageous exemplary embodiment, an electronic information system can also be created. In the exemplary embodiment mentioned, the protective helmet wearer is informed acoustically and / or visually, when he has the protective helmet on, that such roadway hazard conditions exist.

In one embodiment, the electronic communication device 7th an optical output unit. This output unit can be designed simply. It is arranged on the protective helmet. The output unit is designed, in particular, only to output the information. As a result, it can also be made compact. It can be a simple display. It is also possible for the optical output unit to have a head-up display 13. The head-up display 13 is in particular on the protective helmet 1 arranged. It can in particular on the helmet shell 2 be arranged. With the head-up display 13th the information on the road condition can be projected as a virtual image projection into the field of vision of the hard hat wearer. In particular, it can be provided in one embodiment that the visor 6th is designed as a display unit of the head-up display. It can be provided that the electronic communication device 7th is designed to acoustically and / or optically output a driving safety impairment zone characterizing the roadway condition of a roadway as information, in particular to output it to a protective helmet wearer. The driving safety impairment zone shows in particular the roadway dangerous condition. In particular, it has a change in the roadway as set out above.

In particular, a local driving safety impairment zone is to be understood here, which reduces driving safety when driving on and / or driving over with a motorized two-wheeler, in particular in an inclined position.

In particular, this is to be understood in comparison to a roadway condition in which a there is no such permanent or temporary impairment. In this regard, a corresponding impairment is understood as a change, as mentioned above in several examples.

In particular, this is to be understood in comparison to a reference state of the roadway in which there is no such change.

In particular, in one embodiment, in particular in the communication device 7th , Reference information, in particular reference images, are stored that characterize changes. In particular, reference information can be compared with the recorded information to determine the state of the roadway. Depending on this, the recorded information can then be assessed with regard to a change. In particular, in addition to or instead of this, machine training of changes to be recognized is possible.

In one embodiment, the electronic communication device is 7th designed to output the position of this driving safety impairment zone on the roadway and / or the size of this driving safety impairment zone and / or the shape of this driving safety impairment zone as information to the protective helmet wearer. This can also be done acoustically and / or optically. In particular, the electronic communication device is 7th trained for wireless communication with a unit external to the protective helmet. In particular, the electronic communication device 7th a receiver module 14th to receive signals. In particular, signals external to the protective helmet can thus be received. In one embodiment, the electronic communication device 7th a transmitter unit 15th on. With this transmitter unit 15th signals can be external to the safety helmet 1 be sent. In particular, radio signals can thus also be sent and received.

In one embodiment, the electronic communication device is 7th designed to the acoustic and / or optical output depending on a certain distance of the protective helmet 1 to be carried out relative to the driving safety impairment zone. In particular, the electronic communication device is thus 7th also designed to determine the distance to a potential impairment zone on the roadway. In particular, the acoustic and / or optical output can additionally or instead be dependent on other parameters. This can, for example, be the current speed of the motorized two-wheeler and / or a global position of the motorized two-wheeler in a world coordinate system and / or depending on environmental conditions, in particular the current weather, and / or depending on the geometry information of the current lane section of the lane that is currently being driven on, and / or that lane section of the lane that has the impairment zone. In addition to or instead of this, the point in time and / or the type of information on the road condition can not only be dependent on the parameters mentioned above, but also, in addition or instead of this, on the type of change in the section of road that characterizes this dangerous road condition. In this context, it is particularly advantageous, for example in the case of oil or sand or gravel or wet leaves, to inform the driver of the motorized two-wheeler comprehensively and / or as early as possible and thus to output the corresponding information. In particular, such changes are more difficult to detect for the driver of the motorized two-wheeler than, for example, large-area millings or larger lost loads, such as a board or a bag or the like. In particular, if the roadway is additionally wet or is more difficult to see due to a shadow, extensive, adequate and quick information is particularly advantageous for these specific changes.

Additionally or instead of this is the electronic communication device 7th also designed to receive and / or evaluate travel information from other vehicles, in particular other motorized two-wheelers. In particular, such travel information is that which represents the crossing of another motorized two-wheeler in such an impairment zone. In particular, the speed and / or the position and / or the incline of this other motorized two-wheeler when driving over this impairment zone can be taken into account in this context. As a result, individual information can also be output for the helmet wearer. In particular, information from a vehicle dynamics control system and / or an ABS system and / or further driver assistance systems of the other vehicle, in particular of the at least one other motorized two-wheeler, can also be taken into account as information in this context. An additional assessment criterion for the impairment zone can thus also be provided on the basis of this traffic information. In this context, it is not only possible through these parameters to not only recognize such an impairment zone and to generate general information about this. Rather, in one exemplary embodiment, it is therefore also possible to be able to better assess such a detected impairment zone.

Not only in this way it is also possible in one exemplary embodiment to categorize an impairment zone. In particular, in the context of the electronic communication device 7th at least two different categories are provided for an impairment zone. An impairment zone can thus be categorized into at least one of the two categories. In one embodiment, the electronic communication device 7th be designed to individually generate and output information that is then assigned, depending on the categorization. In this context, a more detailed and even more needs-based output of information to the protective helmet wearer can thus take place.

In one exemplary embodiment, the at least hint information can be a symbol and / or text information. As a result, very simple and intuitively easy to understand information is displayed. In one embodiment, a driving trajectory for the motorized two-wheeler and / or an inclined position for the motorized two-wheeler when driving on or driving over the impairment zone and / or by a speed of the motorized two-wheeler when driving on or over this impairment zone can be output as reference information. In an advantageous embodiment, a two-wheeler assistance system is then also provided in principle. In such an exemplary embodiment, not only one determination and / or information system is then made possible. Rather, an actual driver assistance function is then also enabled as an additional function in addition to or instead of this. This possibility of providing the traffic pattern for this impairment zone is also an advantageous exemplary embodiment. Such a driving pattern contains the above-mentioned proposed driving trajectory and / or a proposed lean angle and / or a proposed speed. In particular, this driving pattern can be used with an optical display unit of the electronic communication device 7th are output optically. In one embodiment, this output can be through the head-up display 13th take place. The driving pattern can be output as 2D information or as 3D information.

Driving patterns of other motorized two-wheelers that have driven over the impairment zone and / or have driven past it in the lane in which this is present, and / or the own driving maneuvers of the motorized two-wheeler that drives over or drives past the impairment zone can be analyzed. In particular, this information can also be used for machine training of the communication device or the system. In this regard, the categorizations of a hazard area can be trained as well as the suggestion of driving maneuvers for driving over or driving past the impairment zone.

In general, a relevant roadway condition can also be assessed on the basis of vehicle parameters of motorized two-wheelers that occurred when driving over or driving past. Likewise, the driving style of a driver of the motorized two-wheeler can also be included in the assessment of the road condition in addition to or instead of this. Likewise, the course of the roadway in the area of the impairment zone and / or before the impairment zone and / or after the impairment zone can be taken into account for the evaluation of the roadway condition.

In one embodiment, the hint information can be displayed as augmented reality information. This enables, in particular, a contact-analog representation of such virtual optical information with the real representations of the surroundings. In particular, in an augmented reality display, it is also possible for the wearer of the protective helmet to be shown the impairment zone in a spatially precise and dynamically changeable manner. In this way, the helmet wearer with the helmet on can also precisely recognize at least the position of this impairment zone. In particular when, in an advantageous exemplary embodiment, the driving pattern is also displayed as augmented reality information, driving over or driving past the impairment zone can take place more safely.

In particular, geometry information about the roadway can also be taken into account as information about the roadway condition. For example, a curve radius and / or a curve length and / or a curve inclination and / or an invisible curve behind a crest of a lane section of the lane can be taken into account as geometry information. Such geometry information can also be output acoustically and / or optically by the protective helmet wearer with an output unit of the electronic communication device.

In particular, the cited functions of the electronic communication device can be dependent on a global position of the motorized two-wheeler and / or the protective helmet 1 and thus output to a GNSS position. In particular, in addition to or instead of this, a navigation route of the motorized two-wheeler, with which the protective helmet wearer is traveling with the protective helmet, can be taken into account.

In one embodiment, the type of change that has the reduced-friction state compared to the reference state when driving on or driving over, in particular in an inclined position with the motorized two-wheeler, can be explicitly output optically and / or acoustically. For example, a symbol or a text “Oil” or “Sand” or “Gravel” can be output in this context. The same can also be generated and output for other exemplary changes in this regard, as mentioned above.

It can also be provided that the electronic communication device 7th is designed to dynamically adapt the orientation of an optical information output in the world coordinate system to the head inclination of the helmet wearer relative to the roadway.

In one embodiment, the protective helmet 1 at least one microphone 16 on. In particular, this is in a chin guard part of the helmet shell 2 . This also makes it possible for a protective helmet to be worn when the protective helmet is on 1 can emit a voice signal. This voice signal can be sent by the electronic communication device 7th be evaluated. In this context, this additional information can also be taken into account for determining or assessing the state of the roadway. The electronic communication device can also be trained in this context. In this context, it can check the plausibility of the information acquired with the acquisition units and the conclusions drawn therefrom and / or, if necessary, change and adapt to them. In addition, or instead of this, it is also possible to store voice signals from the protective helmet wearer. In addition to or instead of this, such voice signals can also be transmitted via the transmission unit 15th be sent externally, in particular wirelessly. For example, not only such voice signals but also other signals from the electronic communication device can be used in this regard 7th to a unit of the motorized two-wheeler, with which the protective helmet wearer of the protective helmet 1 is currently on the way. In addition to or instead of this, however, such signals and / or other signals from the protective helmet can also be used 1 to a unit of another protective helmet and / or to a unit of another motorized two-wheeler and / or to a central unit of a communication system with which several, in particular two, separate protective helmets and / or at least two motorized two-wheelers can communicate.

In one embodiment it is provided that the electronic communication device 7th is designed for a current incline of the motorized two-wheeler, with which the helmet wearer of the protective helmet 1 is on the move, and / or to output a current lean angle of this motorized two-wheeler acoustically and / or optically, in particular that it is currently perceived by the protective helmet wearer.

The protective helmet preferably has 1 a banking system 17th on. This can be used to determine the current lean angle and / or a current lean angle of the motorized two-wheeler. For example, this banking system 17th have one or more sensors. These can have gyrometers and / or 3D sensors and / or other position determination sensors. In particular, sensors can be provided in this context, which can determine a pitch angle and / or a roll angle of the motorized two-wheeler.

In one exemplary embodiment, it is provided that, in order to determine the state of the roadway, driving maneuvers by the protective helmet wearer that have been carried out with the motorized two-wheeler or with another motorized two-wheeler in the past are taken into account. Such driving maneuvers can have movement patterns. Such movement patterns can have one or more of the parameters mentioned above, in particular have values of these parameters. In particular, a correlation can also be present as information in the context of which change in the road surface, as mentioned above as an example, which movement pattern was present. In particular, information from an electronic system of the motorized two-wheeler, in particular a vehicle dynamics control system, can be taken into account in connection with such a movement pattern. In this way, a driving situation on a roadway section which has a roadway hazardous condition with regard to an above-mentioned change can be taken into account for the automatic and system-based evaluation of a current roadway hazardous condition. This also means, in particular, that system-side evaluations of roadway hazard states that have been carried out in the past and then actual driving patterns with the motorized two-wheeler and / or, in turn, the actual driving safety states of the motorized two-wheeler resulting therefrom are taken into account and linked. In particular, the driving ability of the driver can also be taken into account not only in this context. In this regard, driving ability can be categorized into at least two different driving ability categories. This can in particular take place, for example, in that the driver himself assesses his own driving ability and as information, for example, to the electronic communication device. However, it is also possible, in addition to or instead of this, to use the electronic communication device to determine the driving ability of the driver 7th itself is assessed. This can be done, for example, on the basis of previous driving maneuvers. In particular, in this regard, an assessment of driving ability can also be taken into account on the basis of driving patterns that have taken place in the past, in particular of dangerous road conditions. In particular, it can thus also be provided that an automatic assessment of the driver's driving ability is also carried out by the electronic communication device 7th he follows. This assessment of driving ability can then also be taken into account in the determination of the roadway condition, in particular when assessing and / or categorizing the roadway condition into one or more dangerous roadway conditions.

In particular, this information about driving ability can also be taken into account with regard to the output of specific advisory information. In this context it can be provided that the condition of the road is assessed as less critical for drivers with high or very high driving ability than for a driver with medium or low driving ability. In particular, such information about driving ability can also be taken into account in the automatic determination of a current driving pattern for driving the currently recognized situation with regard to a dangerous roadway condition. If necessary, a driver with high or very high driving ability can drive into the impairment zone or drive past it with a different driving pattern than a driver with medium driving ability or low driving ability.

In addition to or instead of this, it is also possible for a wide variety of information correlations to be carried out in this way. It is also possible that driving patterns of different drivers in the past who have driven over a road section with a roadway dangerous condition are evaluated. In this context, an averaged driving pattern can then be formed from these different driving patterns. In particular, this averaged traffic pattern can also be provided for the current driving over or driving past the current situation with the dangerous state of the road. In particular, this can also be output accordingly, as has already been explained above.

Such a formation of a mean value can be formed not only for a driving pattern but, for example, for a roadway condition itself. In this context, information from past roadway hazard conditions can be taken into account for the assessment. This information can be particularly helpful with regard to the type of roadway hazard. One type of roadway hazard relates in particular to the type of change in the roadway, in particular with regard to a type of additional pavement on the base pavement.

In one embodiment, the electronic communication device 7th can also be trained by machine. In this context, for example, driving lane hazard states from the past and driving patterns correlated therewith, which were determined to be evaluated with driving patterns then actually carried out, their effect on the safety of the motorized two-wheeler can be evaluated. In this way, for example, machine learning with regard to the provision and offering of driving patterns for driving on a dangerous roadway condition can be improved. In particular, for this training it is possible for the driver of a motorized two-wheeler to take into account not only driving patterns of the road hazard states that were specific in the past and then a comparison with the actual driving patterns with regard to the resulting driving safety. Rather, in addition to or instead of this, corresponding known roadway hazard states and for this purpose from the system or the electronic communication device can also be used 7th certain driving patterns as well as driving patterns actually carried out by comparison with the then evaluated driving safety of the motorized two-wheeler are taken into account for this machine training by one or more other motorized two-wheelers.

Machine training of the electronic communication device can not only be based on this cited exemplary information 7th take place. Other information that has been recorded and / or evaluated, in particular from the electronic communication device, can also be trained. Information available from the past and / or information available from other vehicles and / or protective helmets can also be taken into account for this purpose. In particular, such machine training is also possible for the basic detection of a specific roadway condition, in particular a specific roadway hazard condition. For example, an assessment of a roadway condition as a roadway hazard condition can take place in this context, this initially being done exclusively on the basis of the information provided by the optical detection system of the protective helmet in one exemplary embodiment 1 , in particular with at least one optical detection unit 9 , 10 , be assessed. With regard to this machine training, you can then possibly existing information from other acquisition units of other protective helmets and / or from other motorized two-wheelers and / or from other vehicles that have already traveled on this lane section with the corresponding lane condition and also individually determined and assessed, are taken into account.

In one embodiment it is provided that the protective helmet 1 has at least one optical detection unit, the detection area of which is oriented towards the rear. This optical detection unit can therefore cover the area behind the protective helmet 1 capture. This optical detection unit is thus one that covers the area behind the protective helmet 1 can detect. Especially when the helmet wearer of the protective helmet 1 is traveling with a motorized two-wheeler, the area behind the motorized two-wheeler can thus also be acquired with this at least one optical acquisition unit. This information from this rearward detecting optical detection unit can also be taken into account for the determination of a roadway condition of a roadway. In particular, this information can be used to determine a specific roadway condition, which is determined by the forward-detecting optical detection units 9 , 10 has been recorded, supplemented and / or checked. If, for example, a change in the roadway, in particular the base surface of the roadway, characterizing a roadway hazardous condition, is dimensioned larger, a corresponding detection with the at least one forward-detecting optical detection unit and the rearward-detecting optical detection unit can possibly be carried out at the same time when driving over or driving past.

In addition to or instead of this, it is also possible that when this dangerous road condition or the change in the base pavement causing this dangerous road condition cannot or can no longer be detected with the forward detecting optical detection unit, for example because it has already ended forward, can with the rearward detecting optical detection unit, this change can still be detected. In particular, in this context, for example, a check or plausibility check of that assessment result about the roadway condition can also take place that was carried out with the at least one forward-detecting optical detection unit or on the basis of the information detected with it. In particular, an improvement in the accuracy for determining the state of the roadway can thus be achieved. In particular, however, machine training can also be improved with such a configuration. In particular, if the detection results of the at least one rearward detecting optical detection unit are also used.

In one embodiment, this at least one rearward detecting optical detection unit can also be part of an electronic rearview mirror. In the exemplary embodiment, this electronic rearview mirror can only have one such optical detection unit. This can, for example, be placed centrally in the middle of the safety helmet 1 , especially the helmet shell 2 , be arranged. For example, this can also be at the position at which the optical detection unit is also located 10 , which is detected, for example, to the front, is arranged. For example, the rearward detecting optical detection unit 18th be arranged in the appropriate place. It is also possible for this electronic rearview mirror to have several separate optical detection units 18th has that detect backwards. In this regard, a further optical detection unit in the area of the example in FIG 1 shown, forward detecting optical detection unit 9 be provided. If the electronic rearview mirror has several optical detection units, an optical detection unit can also be external to the protective helmet in this regard 1 , for example on a motorized two-wheeler, with which a protective helmet wearer of the protective helmet 1 is on the way, be arranged. In particular, conventional, non-electronic side mirrors, such as are usually installed on the ends of the handlebars of the motorized two-wheeler on the left and right sides, can be dispensed with with such an electronic rearview mirror. In this context, it can then also be provided that electronic displays are arranged on the motorized two-wheeler, in particular instead of these conventional mechanical side mirrors, in which the images, in particular the videos, are recorded with the at least one optical detection unit 18th recorded.

However, it is also possible for such an electronic rearview mirror to be formed exclusively in that at least one optical detection unit is arranged on a motorized two-wheeler and is arranged to detect it towards the rear. This provides a motorized two-wheeler with an electronic rearview mirror. For example, at least one optical detection unit can be arranged on a rear light of the motorized two-wheeler and / or on a left-hand rear direction indicator and / or on a right-hand rear direction indicator and / or on a left-hand handlebar end and / or on a right-hand handlebar end. It is also possible that, in addition to or instead of this, such an optical detection unit on a holder for a License plate of the motorized two-wheeler is arranged. Furthermore, in addition to or instead of this, other positions on the motorized two-wheeler are also made possible in order to be able to provide such optical detection units for an electronic rearview mirror.

In a further independent aspect of the invention, a protective helmet 1 a road condition information device, in particular a road surface condition device. This can be according to the electronic communication device 7th be trained. In particular, such a protective helmet thus has a road condition information device which can have components and / or functions of the electronic communication device, as is provided for the exemplary embodiments as explained above. In particular, this road condition information device is an electronic road condition information device. In particular, it is an electronic lane danger information device.

Another aspect of the invention relates to an electronic road condition information system 19th . It can do the road condition information system 8th be. The electronic road condition information system 19th is designed in particular to recognize at least one roadway hazardous condition of a roadway. The dangerous state of the roadway is in particular one which, when driving over or driving past with a motorized two-wheeler directly and in an inclined position, potentially impairs or can potentially impair the driving safety of a motorized two-wheeler. In particular, the electronic road condition information system 19th additionally or instead of this, designed to output at least one piece of information about at least one dangerous roadway condition. The road hazard condition is as stated above. In one embodiment, such an electronic road condition information system 19th a protective helmet for a driver of a motorized two-wheeler. This protective helmet is in particular one that is approved for driving a motorized two-wheeler. In particular, the protective helmet is according to one aspect of the protective helmet 1 or an advantageous embodiment thereof.

In a further exemplary embodiment, the electronic road condition information system 19th instead of the hard hat 1 have a conventional protective helmet which does not have an electronic communication device, as set out above, and / or does not have an electronic road condition information device, which has been explained above. In such an embodiment, the electronic road condition information system 19th then an electronic communication device in addition to the protective helmet. This electronic communication device is then arranged in particular outside the protective helmet. The electronic communication device is designed in particular to output the advisory information acoustically and / or optically in such a way that it is perceived by the driver who has put on the protective helmet. In advantageous exemplary embodiments, the electronic communication device can have units and / or functions such as those described above for the protective helmet 1 have been explained. However, these can then in particular be arranged outside the protective helmet. It is also possible for the communication device to have an output unit for outputting the advisory information. In one embodiment, this output unit can be arranged on the protective helmet. As a result, in a further exemplary embodiment, it is possible for only the output unit to be arranged on this protective helmet and for a protective helmet wearer to be able to perceive the reference information directly when the protective helmet is on.

Here, too, the output can take place acoustically and / or visually. In particular, in this exemplary embodiment as well, instead of the electronic communication device, an electronic road condition information device can be present, which can have according to the components as mentioned for the electronic communication device.

In one embodiment, the components of the electronic road condition information system 19th thus be arranged completely on the protective helmet. They are then part of the protective helmet. In further exemplary embodiments, subcomponents of the electronic road condition information system 19th , in particular the electronic communication device or the electronic road condition information device, can also be arranged externally to the protective helmet. For example, components in this regard can be arranged on the motorized two-wheeler. They can also be arranged externally to the motorized two-wheeler and externally to the protective helmet.

In particular, these detection units are oriented in such a way that they detect at an angle downwards. The roadway can thus be detected. In particular, this information can be fed to the optical detection units of the road condition information device and evaluated there. The electronic communication device 32 can also have an output unit in addition to or instead of this 42 exhibit. This can for example be done on the cockpit instrument 30th be arranged.
