Description

The invention relates to a method for providing behavioral information for at least one person. The invention also relates to a driver assistance system and a motor vehicle.

The interest in comfort functions in all areas of daily life is steadily increasing. Above all, functions that serve to maintain and promote health and fitness are becoming increasingly important. As a typical representative in this context calorie counter, nutrition guide and Biorythmustools be mentioned. These may be present, for example, as applications on a portable communication terminal, such as a so-called smartphone. The user can thus always receive information in this context.

In addition, the harmful influence of UV radiation on human skin is receiving increasing attention. On the one hand, the gain in knowledge of recent years contributes to this, on the other hand, the awareness of the increasing intensity of UV radiation reaching the Earth's surface, as a consequence of the thinning ozone layer, increasingly sensitizes people.

A distinction is made between UV-A (315-380 nm), UV-B (280-315 nm), and UV-C radiation (100-280 nm). The UV-C radiation is almost completely absorbed by the atmosphere. About 90% of the UV-B radiation is absorbed by the ozone layer and the UV-A radiation reaches the earth's surface almost unhindered. While UV-B radiation can not penetrate ordinary window glass, most of the UV-A radiation passes through. Only specially treated glass can also protect against UV-A radiation. In the case of automobiles, only the windshield often has such a protective effect, so that it can also lead to significant UV radiation exposure in the vehicle interior.

The object of the present invention is to provide a method which offers a person a comfort function in connection with the sunshine.

In particular, a driver assistance system and a motor vehicle are to be created, with which such a comfort function can be provided.

This object is achieved by a method, a driver assistance system and a motor vehicle according to the independent claims.

In the method according to the invention, at least one behavioral information is provided for at least one person. This behavioral information is created with respect to a local action or local effect of the sun's rays or solar radiation. The solar radiation is detected with at least one sensor arranged on a motor vehicle and the radiation intensity of at least one UV (ultraviolet) spectral region of this solar radiation is determined at the location of the motor vehicle depending on information of the sensor or sensor information generated by the sensor. Depending on this, at least one behavior information relevant for this location is then generated for the person and this behavior information is output to the person. It is also possible, based on the sensor information, to generate at least one information relevant to this location regarding the intensity of the solar radiation and from this the behavioral information for the person to be generated or derived.

By means of the method according to the invention, information about the solar radiation at a current location of the motor vehicle is obtained in a particularly advantageous manner by the motor vehicle itself, namely the sensor arranged thereon or therein. The person is then informed and, in the context, a recommendation given by the behavioral information is generated, which is transmitted to the person. As a result, it is now also possible for any unwanted solar radiation to be detected early on the person, and the person can then react accordingly on the basis of the behavioral information.

It can therefore be detected and reported in an advantageous manner, possibly unwanted sunlight on the person early. In particular, the behavioral information may be a recommendation to the person as to how health is currently being protected, and possibly also in the future. By way of example, the information provided may contain, for example, the warning of a hazardous UV radiation exposure and / or the warning of a health-threatening overheating of the body. Furthermore, details of the possible harmful effects can be given. These can be, for example, probabilities for the occurrence of damage, its symptoms and their time course.

The fact that the behavior information for the current location, for the current time and also person-specific can be provided directly from the vehicle itself, represents a significant advantage of the presented method.

In particular, a health information directly or in the future possibly protective behavior information is thus generated for at least one person. This is particularly advantageous when the person is in the vehicle and this is exposed to direct sunlight, which can also lead to a harmful UV radiation exposure in the interior of the motor vehicle. In motor vehicles with a top, which can be opened, the so-called convertibles, this solar radiation can reach the person in the vehicle even directly. If the motor vehicle then remains at this location for an extended period of time or if there is a stoppage of the motor vehicle or only a very slow movement (for example because of a traffic jam), this behavioral information generated can have a significant advantage with regard to avoiding the possibly occurring health impairment Person in further this regard sunshine mean. For example, it is possible to warn the person of sunstroke and / or damage to the skin.

But even if the motor vehicle is moving and a relatively rapid change of location takes place, this behavioral information can be very useful for the person. For example, this may be the case when regionally across a corresponding or high solar radiation such as at the location of the motor vehicle and in its further movement with a comparable solar radiation (at least for a specific period of time) in other places, which then reaches the vehicle be expected.

Moreover, in a method according to the invention, the provision of the behavioral information may also be useful when the person is outside but in the immediate vicinity of the motor vehicle, for example when the motor vehicle is being cleaned or when parked in an adjacent parking lot. This may be the case, for example, when the person is in a nearby recreational area, such as a park or a spa. The behavior information can therefore be transmitted from the motor vehicle to the person, for example via a radio link.

Preferably, a radiation intensity of the incident solar radiation with a rain-light sensor, which is arranged on the motor vehicle, measured. The rain-light sensor can be arranged or integrated in the motor vehicle. For example, the rain-light sensor may be mounted behind the windshield. Such a rain-light sensor is usually already present in the motor vehicle to detect, for example, precipitation and depending on it, for example, to control a windshield wiper. A very component-minimal design and thus cost-effective implementation of the invention without additional sensors is possible.

The incident through the windscreen of the motor vehicle solar radiation is detected by the rain-light sensor. This is therefore arranged so that the incident solar radiation can be detected as far as possible and safe. This favors the quality of the data derived from it and finally the meaningfulness of the behavioral information provided.

It is preferably provided that the radiation intensity of the UV-A spectral range and / or the radiation intensity of the UV-B spectral range are determined. It is precisely these specific spectral regions of the sunlight striking the earth, depending on the respective intensity and / or duration, with which or on which they irradiate a living being, in particular a person, cause corresponding immediate or temporally in the future health impairments. Therefore, it is particularly advantageous if both the UV-A spectrum and the UV-B spectrum are determined with the respective radiation intensities. The scope and accuracy of the behavioral information can be increased thereby.

It is preferably provided that a maximum residence time at the location for the person exposed to solar radiation is specified as behavior information. This length of stay should indicate that, if exceeded, a person with a health impairment with a corresponding probability value exceeding a probability threshold must be expected.

In a further advantageous embodiment, it is provided that a minimum value of a sun protection factor for a sunscreen to be applied to the skin of the person is specified as behavioral information.

Another behavioral information may be, for example, the recommendation to put on a headgear, such as a cap, a hat, etc., and / or to pull down a sunshade in the motor vehicle and / or close a roof window of the vehicle and / or close a vehicle roof.

Each of these pieces of information is thus in particular a recommendation as to how the person should behave if he continues to prevail at the place of the motor vehicle Sun exposure and / or suspend in the foreseeable future accordingly. The recommendation in the Behavioral Information is therefore particularly aimed at maintaining the health of the person. It can thus be avoided, for example, a sunburn and / or sunstroke. Also a long-term health impairment, such as skin aging, and especially skin cancer, can be counteracted.

In a particularly advantageous embodiment, it is provided that personal information given by the person and taken into account in the determination of behavioral information. As personal information, for example, a skin type can be specified. In addition, it can also be indicated how many sunburns the person has suffered within a past time interval and / or how many sunstrokes the person has experienced in a past period of time. In addition, as personal information, for example, can also be entered, for example, if the person is already suffering from a skin cancer. Here, for example, the severity and / or the type of skin cancer can be specified. Because of this specific information can result in different risks for a person in an individual sunlight, then in turn can be generated depending on more precise and more personal behavioral information.

It is preferably provided that individual behavioral information is determined for at least two persons and, in particular, is output at the same time. The behavioral information is then individually tailored and allows for the respective person, including a group of people who is in the vehicle and / or is located at a short distance to the motor vehicle, individually adapted recommendations for further behavior.

It can be provided that these individual behavioral information are also preferably output simultaneously. It may also be in the context of the output to a single output unit. The output unit may be arranged in the motor vehicle itself, but it may also be a portable and thus mobile communication terminal. For such output to a single output unit, it is then also possible for a first person perceiving the behavioral information, for example, to communicate the behavioral information to a second person, who currently has no possibility of being aware of the behavioral information assigned to him or her gain.

It can also be provided that the output of a plurality of behavioral information for each different person at a single output unit for certain people can be individually enabled or disabled. Thus, for example, behavioral information can be prevented from becoming known to a person for whom it is not intended.

It may be provided that the sensor arranged on the motor vehicle for detecting the solar radiation is also embodied in the UV spectral range, in particular in the UV-A spectral range and / or in the UV-B spectral range. In such an embodiment, the solar radiation of these spectral regions can be detected directly by the sensor and the radiation intensity can be determined as a function thereof. From this, an individual behavioral information for a person can be generated again.

Just when a sensor which is already installed on the motor vehicle, in particular a rain-light sensor, is used to determine the radiation intensity in the UV spectral range of the solar radiation depending on its measurement information, the solar radiation is detected in the UV-A and / or UV-B spectral range indirectly. Usually, such a rain-light sensor is sensitive in the infrared spectral range, whereas it is not sensitive or insensitive in the UV-A spectral range and in the UV-B spectral range.

In such a configuration, a radiation intensity of a spectral range of the solar radiation outside the UV spectral range is then measured with the sensor, in particular the rain-light sensor, and depending on this, the radiation intensity of the UV spectral range of the solar radiation currently incident on the motor vehicle is determined. Therefore, a conventional sensor present on the motor vehicle, namely the rain-light sensor, can be used without adaptation, as a result of which a very cost-effective implementation of the method is ensured.

In particular, it is provided that this radiation intensity of the UV spectral range of the solar radiation currently incident on the motor vehicle is estimated as a function of the radiation intensity of the spectral range outside the UV spectral range. For this purpose, a device of the motor vehicle, which also comprises this at least one sensor, an evaluation unit, which can perform such an estimate. In particular, it is provided that the estimation is carried out depending on the known and, in particular in the evaluation, stored intensity distribution of the electromagnetic spectrum of solar radiation. This electromagnetic spectrum The solar radiation is known and has the highest intensity in the range of visible light.

The behavior information is preferably visually displayed in the motor vehicle via an output unit, in particular on a display unit such as a display. For example, this may be the display unit of a navigation system or infotainment system of the motor vehicle.

It may additionally or alternatively also be provided that the behavioral information is output to a portable communication terminal, for example a smartphone or a so-called tablet. The behavior information can be visually displayed in particular via a display unit, such as a display, of the communication terminal. For example, the behavioral information can be transmitted from the motor vehicle to the communication terminal, for example via a radio link. It can be done here a visual display with symbols and / or text and / or numbers. In addition, an output of an acoustic signal can also take place.

It can preferably be provided that the behavior information is transmitted wirelessly to an output unit or a portable communication terminal.

Furthermore, the invention also relates to a driver assistance system having at least one sensor for detecting solar radiation, and to an evaluation unit for evaluating the information of the sensor, and to an output unit for outputting behavior information, wherein the driver assistance system is designed to carry out a method according to the invention or an advantageous embodiment thereof is. Furthermore, the invention also relates to a motor vehicle with a driver assistance system according to the invention or an advantageous embodiment thereof.
