Description

The invention relates to a method for outputting a signal status of at least one traffic signal device, in particular a traffic signal device such as a traffic light.

Corresponding methods for outputting a signal state of a traffic light detected via a detection device on the vehicle are basically known from the prior art. For example, traffic signs are recorded on the vehicle side and a symbol representing the traffic sign is output in the form of a graphic reproducing the traffic sign in a head-up display or a vehicle-side screen.

The invention is based on the object of specifying a method which improves the perceptibility of a signal state of a traffic signal device for a vehicle occupant, in particular with regard to a measure that can be perceived simply and quickly. Furthermore, the support measure for the vehicle occupant should take place without the information being overloaded or the vehicle occupant being overwhelmed by the information supplied.

The object is achieved by a method for outputting a signal status of at least one traffic signal device, in particular a traffic light, according to claim 1 and by a vehicle, in particular a motor vehicle, according to claim 12. The dependent claims relate to possible embodiments of the method.

The invention relates to a method for outputting a signal status of at least one traffic signal device, in particular a traffic light, with the following steps: a) requesting output information that can be output or output via an output device by a person on or in a vehicle, b) detecting the signal status of the traffic signal device by means of a detection device, c) generating signal state-dependent output information based on the detected signal state, d) outputting the signal state-dependent output information to the output device, the signal state-dependent output information being output at least in time and / or in sections, in particular completely, in such a way that this output information is for a color-blind or partially color-defective person is clearly perceptible.

A traffic signal device may, for example, be a traffic light such. B. concern a traffic light directed to motorists and / or a tram traffic light and / or a bicycle traffic light and / or a pedestrian traffic light. Alternatively or additionally, a traffic signal device can comprise a barrier and / or a sign indicating a barrier or a traffic light indicating a barrier. Alternatively or additionally, a traffic signal device can relate to a garage entrance and / or exit traffic light. In the case of a barrier, the position of the barrier can output its signal status. Optionally, street lighting and / or a traffic sign, in particular specific to a route section, can be viewed as a traffic signal device in the present sense. In this case, street lighting can include, for example, active lighting and / or passive or reflective lighting, in particular provided with its own or associated lighting means. Such street lighting can include, for example, direct or indirect lighting of a pedestrian crossing, which differs from street lighting of a route section not provided with a pedestrian crossing,

In general, a signal state can include any state of a traffic signal device; in the case of a traffic light, this can relate to the switch positions green, yellow and red. Alternatively or additionally, for example, a signal state of the traffic signal device can comprise an in-operation state and a non-in-operation state of the traffic signal device. Here, in the case of a traffic signal device designed as a traffic light, the not-in-operation state z. B. be signaled by flashing, ie that in the not-in-operation state, the traffic light is in operation, but does not output any traffic regulating or controlling information for road users. Only the information that the traffic light is not being observed or that it is required to observe any traffic signs or subordinate traffic rules (e.g. right-before-left) can be obtained by recognizing the deactivated traffic light. Alternatively or additionally, for example, a bar arranged temporarily on a traffic sign by means of a cover and / or a bar can mean that the signaling function of the traffic sign is overridden, this information being able to be output as output information. In the case of a traffic signal device designed as a traffic light, for example, at least the following signal states can be recorded and possibly output in the form of output information: a) green, b) yellow, c) red, d) flashing at least one signal color, e) out of operation, f) notice on active switching ends (e.g. as Traffic light device) or static (e.g. sign) right-turn arrow, g) traffic light deformed (e.g. deformed in the course of a collision). For the recorded out-of-service scenario, different sub-states can be recorded and, if necessary, also output using the output information; this would be, for example, a reference to a traffic sign that must be observed in the case of the deactivated traffic light, or an indication that the traffic light is deactivated and there are no traffic signs influences the right of way rules so that the right to left rule applies.

Depending on navigation information, it can be provided, for example, that the output information is only output for a route-relevant traffic signal device and / or takes place in a highlighted or highlighted manner for route-relevant traffic signal devices.

The output information is output at least in response to a request or to a request for this output information by at least one person on or in a vehicle. Because the at least one output information item occurs in response to the request, at least this output information item cannot surprise the at least one person in or on the vehicle or cause at least this person no major distraction. This increases safety in road traffic, since the potential for distraction for the person in or on the vehicle, in particular for the driver, is reduced.

The vehicle, in particular the single-lane or multi-lane motor vehicle, can be designed, for example, as a car or two-wheeled vehicle or a utility vehicle. The vehicle can also comprise, for example, a rail-bound vehicle. It is possible that the vehicle comprises a watercraft and / or an aircraft. In the case of a watercraft, the traffic signal device can for example comprise a lighthouse signal lamp and / or a bridge marking. The bridge marking can include status information for the passage of fixed or mobile bridges, for example. In the case of an aircraft, the traffic signal device can for example comprise a taxiway signal light.

The signal state-dependent output information output via the output device is carried out in such a way that the output information can be perceived in a simple and therefore easily understandable and unambiguous manner by a person with color deficiency or partial color deficiency. This increases the safety of road traffic or rail and / or water and / or air traffic. The invention thus works in two ways to increase safety, since there is no distraction by unexpected or "spontaneously" information and at the same time the expected - as requested - information requires a low level of attention for a defective person or a color or partially color defective person to “read” or perceive and classify this information. Since the stimuli of the environment and / or traffic events and / or the information or feedback from the technical vehicle system that can be perceived in or on the vehicle increase in particular for people with color or partial color vision deficiencies Demanding attention, the method according to the invention can make a contribution to increasing safety by relieving the load on the vehicle occupant, in particular the driver.

Ametropia: in addition to nearsightedness, I am not far sighted.

A color defective or partially color defective person means here, for example, a person who suffers from red-green visual impairment or red-green blindness. In essence, this is a disruption of color perception, with those affected being less able to distinguish between the colors red and / or green than people with normal vision. An at least partial ametropia or difficulty in a quick and / or unambiguous detection of other color spectra can also be understood in the present case as a person with color deficiency or partially color defective vision.

It is possible that the output information is output or can be output optically and / or acoustically and / or haptically via the output device. Because the output information that is dependent on the signal state is output acoustically, it can be clearly and unmistakably understood by a person suffering from color blindness or partial color blindness. An optical output of output information that is dependent on the signal state can take place, for example, in a color or in a color spectrum which can be easily recognized by a person with ametropia or red-green weakness. The output can take place, for example, in the colors purple or orange, which can be easily perceived by the person who has a red-green weakness. A haptic or tactile output can include, for example, an at least section-wise vibration of a seat surface of a vehicle occupant and / or a vibration of a steering wheel and / or a vehicle pedal.

In a preferred embodiment it can be provided that the output information is output as a displayed geometric body and / or as an alphanumeric character and / or as at least one word and / or as a symbol, the respective output elements being designed differently depending on the detected signal state are. The geometric body output as output information preferably comprises, for example, the shape of a triangle and / or a square and / or a cross and / or a square and / or an n-corner and / or a circle and / or an oval. The geometric shapes mentioned can be understood, at least in sections, as the basic shape of the respective shapes, so that, in particular, slight deviations from the basic shape are still included. For example, the geometrical shapes mentioned can be present in spite of rounded corners. Alternatively or additionally, a visually perceptible signal state-dependent output information item can include the display or output of geometric bodies and / or alphanumeric and / or at least one word and / or symbols as symbols. The different geometric shapes depending on the signal state can optionally be displayed in different colors. A light intensity and / or a contrast and / or a light rhythm can also be output or displayed in a changed manner as a function of the signal state.

The output information can include, for example, a colored element, in particular a monochrome or multicolored element, which is output at least in sections, in particular completely, in different color spectra or in different colors, depending on the detected signal state. A first signal state is preferably displayed in a first color spectrum and a further signal state different from the first signal state is displayed in a further color spectrum different from the first color spectrum.

It is possible that the signal state-dependent output information can be or is modified at least for one signal state, in particular for at least two or for all signal states, by a vehicle occupant and / or by a higher-level central device. This modification or determination of the type and manner of the output information relating to a definable signal state of a traffic signal device enables an increase in safety in road traffic or in the use of a vehicle comprising the method described herein. Because the output information that is dependent on the signal state can be individualized, in particular by a vehicle occupant, a manner of presentation that is familiar to the vehicle occupant, in particular to the driver of the vehicle, can be output. The distraction potential and / or the interpretation of the output information provided to a vehicle occupant, in particular a driver, and requested by this or another vehicle occupant is thus low or simplified. An assignment of a defined signal state to a defined or definable type of output information can be filed and / or stored in a data memory, in particular arranged on the vehicle side. Alternatively or additionally, the data memory with the assignment information regarding defined signal states and a manner of output information defined for this purpose can be stored in a mobile terminal device, in particular a smartphone, preferably a vehicle occupant, and possibly transmitted to the vehicle and / or to the output device . The mobile terminal can be designed, for example, as a portable electronic terminal or as an electronic mobile device. In particular, a smartphone and / or a tablet computer and / or a portable computer (e.g. laptop) can be used as the electronic terminal. For example, it is possible for the color and / or the geometric shape of a signal state-specific output information item to be adjustable or configurable for defined signal states.

For example, in the case of an exclusive ametropia with respect to. A certain color and / or a certain color spectrum, z. B. the color red, only for this color relevant signal states of the traffic signal devices are output in an output information such that they can be easily recognized by people with a corresponding color ametropia. Thus, for a person who only has an ametropia for the color red, the method can be carried out in such a way that only red-specific or red-critical signal states of traffic signal devices are output as output information in accordance with the method. In this example, the color green can be output unchanged or without a process-specific measure.

Preferably, at least one output information item that is dependent on the signal state, at least for one signal state, in particular all signal states, is configured differently or can be configured differently for specific vehicle occupants. In this way, the manner and / or the duration of output information can be set up individually for a vehicle occupant, in particular for a driver, so that the perception of this output information can be output to this vehicle occupant in a quick and clearly detectable manner.

The request for the signal state-dependent output information can be initiated or can be initiated, for example, by means of at least one acoustically perceptible and / or optically perceptible and / or tactilely perceptible event carried out by a vehicle occupant, in particular a driver. A vehicle occupant, in particular the driver, of the vehicle can transmit the request, for example, by sending out an acoustic and / or optically perceptible and / or tactilely detectable signal. It is thus possible, for example, for a driver or a front passenger to initiate a request regarding the signal status of a traffic signal device that can be detected in the surroundings or by the detection device through a verbally expressed question. Alternatively or additionally, the person can carry out a gesture and / or carry out a facial expression and / or press a key and / or touch a touchscreen, the respective action of the person being recorded by a corresponding recording means. The request for the signal state-dependent output information can alternatively or additionally be initiated, for example, by touching an input unit and / or by recognizing a gesture by a person and / or by recognizing a direction in which a vehicle occupant is looking and / or by recognizing a sound or speech signal from a person will or can be initiated.

It is possible that, in the course of the request, the signal status of a certain traffic signal device from a group of possible traffic signal devices can be specified, so that the request relates to a certain traffic signal device and its signal status is output separately or exclusively and / or in a highlighted manner .

It is possible that the way in which the signal state-dependent output information is requested can be modified or specified. Preferably, the manner in which the signal state-dependent output information is requested can be set and / or specified in a vehicle occupant-specific manner. In other words, the type and manner of the request or the command for initiating signal state-dependent output information can be set and / or specified in a user-specific or individual manner for a vehicle occupant, in particular a driver. This can be done automatically, for example, so that a user-specific way of requesting at least one request type is stored or can be saved from a data memory. So that the driver-occupant-specific, in particular driver-specific, type of request is taken into account by reading out the data memory and a corresponding type of request transmission or command input of the output unit or the means controlling the output unit are taken into account. Analogously to this, the type and manner of person-specific output information can also be stored or can be stored in a data memory, in particular in the same data memory as the type and manner of the request or the request command. For example, it is possible for a sensor device to identify a vehicle occupant, in particular a driver, and either directly or after confirmation by a vehicle occupant, in particular by a driver, the information stored in the data memory about the manner in which the request is executed or the output information and / or the request or the request command are taken into account for the method.

In addition to the signal state-dependent output information output on the basis of a request, for example at least one piece of information about the signal state of at least one traffic signal device independent of the request can be provided on the output device and / or on an output device separate from the output device. In addition to the requested output information, further or additional information information relating to at least one traffic signal device can thus be output. It is thus possible that the information information, in particular unsolicited and / or permanently output, outputs basic information about several potentially relevant traffic signal devices and the output information to be requested outputs the signal state-dependent output information in a different way than the information information, in particular in a highlighted and / or parent way that issues. For example, the information information can output a permanent display of the signal states as symbols for all traffic signal devices or only for a fraction of the traffic signal devices as optical elements, with the output information of a specific traffic signal device or a subgroup of the traffic signal devices output via the information function also being able to be output in the event of a request is.

In a further advantageous embodiment it can be provided that time information on at least one time aspect of the traffic signal device relating to the signal state is output or can be output. In particular, the time information is output at the same time as the output information and / or integrated in the output information. For example, the at least one time aspect of the traffic signal device and / or the signal state-dependent Time information relating to output information relates to a prediction of when a signal state changes from a first to a further signal state. In this case, for example, information from the observation of the traffic signal device, in particular a traffic light, by historical data, e.g. B. observation data by repeatedly driving the route and / or from observation information from other vehicles that have passed and / or observed the traffic signal device and / or originate from a higher-level information device or this observation information can be accessed.

In a further embodiment, the time information relating to a time aspect of the traffic signal device can optionally include the duration of a, in particular currently, present signal state and / or the remaining duration of an, in particular currently, present signal state and / or a probability of a time aspect output via the time information, in particular a duration or the remaining duration. The time information can be generated and / or influenced, for example, based on information from the detection device of the vehicle outputting the specific time information or output information and / or based on information from detection devices of other or further vehicles. By outputting time information, the output information outputting the signal status can be upgraded, since the at least one vehicle occupant, in particular the driver, can decide or filter for themselves whether the originally requested output information is outputted in connection with the signal status-dependent output information Output information is (still) of interest to him based on the time information with the output time component. Finally, this aspect also enables a reduction in the level of attention required by the vehicle occupants, in particular the driver, so that a further increase in road safety is made possible. For example, the detection device of the vehicle or of a further vehicle can detect a signal lamp of the traffic signal device that outputs a time aspect as information and output this information as time information.

It is possible that a request for signal state-dependent output information from a defined traffic signal device from a group of at least two traffic signal devices is made on the basis of suggestion information output by the vehicle. In other words, the suggestion information offers a vehicle occupant, in particular the driver, the output of output information relating to a specific traffic signal device from a group of possible traffic signal devices, the output information only finally being given at the request of the vehicle occupant, in particular the driver. Preferred is the proposal of a request for a defined traffic signal device in the course of the proposal information from at least one vehicle occupant and / or from the person of the driver and / or from historical route data and / or from the signal status of the traffic signal device and / or from a time aspect of the signal status of the traffic signal device and / or on a current route guidance of a navigation system and / or on an activated direction indicator of the vehicle and / or on a driving speed of the vehicle and / or on an acceleration of the vehicle and / or on historical request data of the vehicle occupant, in particular the driver. An optional dependency of the suggestion information for a request for signal state-dependent output information from the driver can include, for example, that, depending on the person of the driver, suggestion information that is different in type and / or scope and / or time is output. As an alternative or in addition, the suggestion information can be provided as a function of a further vehicle occupant. Alternatively or additionally, the dependency on a vehicle occupant, in particular on the driver, a detection and / or assessment of their state of health and / or wakefulness, a change in the manner and / or time aspects (e.g. display duration) can take place. Another alternative or additional dependency of suggested information can include, for example, a predicted or existing critical or difficult traffic situation. For example, a journey along a construction site section can be recognized and, in comparison to other driving situations, suggestion information and / or a different, in particular clearer and / or larger and / or highlighted output of the suggestion information can take place earlier. The suggestion information that has a supporting effect can thus intervene in scenarios, for example, when an impairment or behavior that is untypical for a vehicle occupant, in particular a driver, is detected.

In addition to the method, the invention also relates to a vehicle, in particular a motor vehicle, comprising an output device and a detection device for carrying out a method according to one of the preceding claims described herein.

All advantages, details, designs and / or features of the method according to the invention can be transferred or applied to the vehicle according to the invention.
