In the event of a detected fatigue, the driver assistance system can prompt the driver, for example, to take a break by means of a visual display and / or a haptic or acoustic signal. In the event of a detected collapse, the driver assistance system can stop the vehicle and initiate first safety measures in road traffic, for example by activating the hazard warning light system.EP 1 726 513 A1 discloses a driver assistance system having a lane keeping function, a lane change module, a driver state monitoring system and a decision module, wherein the decision module can generate warning signals and actively intervene in the movement of the vehicle.

The air vent contains an outflow nozzle, air flow guiding elements, for example slats and / or flaps, and at least one electrically controllable actuator, for example a servomotor, a direct current motor with a gear mechanism or a stepper motor. Each actuator is operatively connected to one or more airflow directing elements to change the position of these airflow directing elements when the actuator is actuated such that the airflow is deflected in a selectable direction or airflow is prevented from exiting. With the air vent it is possible to adjust the outlet direction of the air flow remotely and without manual intervention or to close the air vent as required.DE 101 21 909 A1 shows a ventilation device for vehicles, in particular in conjunction with a heating or air conditioning system, having air flow channels and at least one air vent having devices for controlling the air direction and the air quantity. This is intended to provide a ventilation device for a motor vehicle which has an electrical actuation of the elementary functions of the air vents. For this purpose, it is provided that at least the devices for controlling the air quantity and for controlling the air direction of the air vent can be electrically actuated. It is the object of the invention to provide a method and a technical unit with which the driver can be acted upon if a concentration deficit is detected or assumed in the latter.These objects are achieved by the method having the features of claim 1 and the technical unit having the features of claim 9. Claims dependent on claim 1 or 9 relate to advantageous further developments.A first aspect of the invention relates to a method for improving or cancelling a deficiency in attention of a driver when moving an ego vehicle having a technical system for automatic or partially automatic driving, in which the technical system establishes that a first route section in which automatic or partially automatic driving is possible in a level X transitions into a second route section in which automatic or partially automatic driving is no longer possible safely in the level X, with the result that the driver has to actively take more control of the vehicle again within a predefined return time, the end of the first route section is indicated to the driver by a first signal, for example optical signal, after a predefined or predefinable time after the start of the output of the first signal via an interface, in which the technical system is connected to an automatic climate control system of the ego vehicle, the automatic climate control system is activated and / or preset, and the driver, if he does not react or does not react appropriately after expiration or partial expiration of the predefined return time, is actively blown by the automatic climate control system.In automatic driving or partially automatic driving, the driver is relieved by corresponding automation during driving. Automatic driving is also referred to as autonomous driving, and partially automatic driving may be referred to as partially autonomous driving, respectively. In order to make the application easier to read, the term automated driving is usually referred to below, wherein the automated driving also comprises partially automated driving.The activation of the climate control system can comprise in particular a preparation of the climate control system or of parts of an climate control device, which can be set by the climate control system, for focusing the climate control system or an air flow from the climate control device onto the driver. The activation of the air conditioning system can prepare an adjustment of parts of the air conditioning unit, for example set a motor for adjusting an air vent from "off" to "standby", so that the air conditioning unit can react without delay in the event of an activation. The fact that the automatic climate control system is prepared means, in other words, that the automatic climate control system is placed in a type of standby mode and can therefore react substantially without delay if the driver has not reacted or has not reacted sufficiently after expiration or partial expiration of the return time.In the context of this application, stand-by mode is understood to mean that the technical system for automatic or autonomous driving can be connected to the climate control system via an interface, such as a control unit of the technical system, for example, so that the climate control system or parts of the climate control system can be activated depending on predefined events and optionally further specifications.The technical system can comprise a plurality of mutually distinguishable warning levels which are activated at different time intervals with respect to the triggering event, for example a change in the level of automated driving. These warning levels can comprise, for example, an initial brake jerk in order to gain the attention of the driver.The initial warning stage or further warning stages can be, for example, a vibration of the steering wheel, an acoustic signal, such as a warning tone, an optical output, such as a color change of the vehicle interior lighting and / or, for example, a flashing warning sign on a head-up display, and / or another known warning signal, such as a warning tone. The prepared automatic climate control system is advantageously activated finally only when the driver does not react, or does not react sufficiently, to the first warning level within the predefined or predefinable return time. As a sufficient reaction, it can be regarded, for example, that the driver changes the position of his seat, places a book or a smartphone, etc. away, places the coffee cup off, opens closed eyes or grasps the steering wheel again with his hands.The preparation or a preparation time of the climate control system and / or the predefined return time can depend on the change between stages of automated driving.Thus, the preparation time and the recovery time can be shorter or longer when changing from level 2 to level 1 than when changing from level 3 to level 2 or from level 3 to level 1. X can stand for example for the numbers 1 to 5, including intermediate values, such as 2.2 or 2.22, etc., Y can stand for example for the numbers 0 to 4, including intermediate values. As a rule, X is always greater than Y, that is to say X stands for a higher level of automated driving than Y.The climate control system or air conditioning system can be activated to change a direction, intensity and / or temperature of an air flow that is currently blown from the air conditioning system into an interior or passenger compartment of the ego vehicle. In particular, the climate control system can focus the air flow onto the driver. For this purpose, for example, all air vents that are not directed or can be adjusted to the driver can be closed. As a result, the air flow of the air conditioning system is exclusively and directly directed onto the driver. The air blown onto the driver can be, in particular, cooled air, so that the air flow can also be referred to as a cooling flow.A target value of the air flow or cooling flow, which is to be blown by the air conditioning system into the interior of the ego vehicle or directly onto the driver in response to the data recorded by the sensor system, can be calculated by a control unit, for example a control unit for the air conditioning system. In order to calculate the time requirement from a current initial value until the target value is reached, the control unit can comprise a computer unit which can calculate an optimum air or cold flow, an optimum temperature of the air or a target temperature for the air on the basis of known data, such as the predefined return time for the driver, and received data, such as, for example, a temperature in the ego vehicle, an external temperature, a humidity, etc. However, the control unit can also comprise an internal memory or be connected to an external memory, such as a cloud, in which a characteristic map is stored, from which the computer unit uses the measured temperature values to determine the target values, such as the air mass flow and / or air temperature for the air flow of the air blown onto the driver, by interpolation.The climate control system comprises at least one electronically controlled air vent. At least one parameter of the air flow blown from the air vent or air inlet into the interior of the ego vehicle can be adjusted by the climate control system, so that the desired air flow is blown to the driver at the predefined time.The parameter or parameters can be, for example, the direction of the air flow, the duration of the air flow, the intensity of the air flow and a setting of a pulsation of the air flow blown from the air vent onto the driver according to pulse duration, pulse intensity, etc.The method defines a new interface in which the technical system for automated driving can be coupled to an automatic climate control system in order to selectively inflate the driver by the automatic climate control system in connection with a change of automated driving.In order to address the driver in a targeted manner, an air flow of the climate control system is directed directly onto the face or the eye section of the driver. If the sensor system establishes that the driver is a spectacle wearer, regardless of whether temporarily using sunglasses or due to a lack of vision, a direction and / or intensity of the air flow to the eye portion of the spectacle wearer can differ from the direction and / or intensity of the air flow for the eye portion of the non-spectacle wearer.The method according to the first aspect can advantageously also be used to alert the driver of an ego vehicle with ADAS level 3, 4 or higher in good time that the ego vehicle is briefly changing from an operational design domain (ODD) for which the ego vehicle is permitted to a lower ODD or leaves the ODD and the driver has to take over more control or control of the ego vehicle again. The driver can thus be blown via the air conditioning system in order to signal the end of the ODD to him. In this case, the driver can be blown with continuously increasing intensity in order to signal that the time until the control over the ego vehicle is taken over becomes ever shorter.In addition, the technical system for automated driving can comprise a driver assistance system having a sensor system for observing the driver. The sensor system can be used to continuously record the current position of the driver's head, for example. The position of the head can be taken into account in the preparation and activation of the climate control system.The sensor system makes it possible to ascertain, independently of automated driving, that the driver has health problems, is distracted, is drowsy or is encumbered. The climate control system can also then be activated in order to wake up the driver or to put it fit again. If the behavior or posture of the driver does not change within a predetermined time, the method can automatically stop and secure the vehicle, e.g., hazard warning light, horn, flashing driving light, and automatically issue an emergency call.A second aspect of the invention relates to a technical unit for a vehicle having a technical system for automated driving of the vehicle, a driver assistance system which monitors at least the driver of the vehicle by means of a sensor system, sensors for detecting an internal temperature in the vehicle and an external temperature, a warning signal generator, an automatic climate control system for controlling the temperature of an interior of the vehicle and a control unit, characterized in that the control unit forms an interface via which the technical system can be connected to the automatic climate control system.The fact that the driver has a deficiency in concentration can mean that the driver shows signs of fatigue, makes unusual movements due to pain or cramps, does not grip the steering wheel over a predefined period of time, directs the gaze not to the traffic but, for example, to a monitor of a mobile telephone, laptop or reads a book during automated driving. The concentration deficiency may be that the vehicle travels automatically at ADAS level 3 or higher without the driver assistance and approaches the end of the operational design domain (ODD) for which it is permitted, and the driver cannot recognize that he is aware of the near end of the ODD. By means of the technical unit, the driver can be made aware that he is to prepare himself to take over control of his vehicle again at the next time.If the technical system is connected to the climate control system via the interface and the driver does not react to a level change announced by the technical system, the climate control system can be focused on the driver. This can mean, for example, that only the driver is blown with air from the climate control system.The climate control system of the technical unit can comprise at least one electronically controlled air vent via which air can be blown into the interior of the vehicle. With the aid of the at least one air vent, at least one direction of the outflowing air flow can be determined. For example, the air can be directed directly onto the face of the driver, the neck thereof or the eye portion thereof in order to achieve the best possible effect. The duration of the air discharge can be regulated via the air inlet. The air output via the at least one air vent can be continuous or clocked or pulsating. The cycle sequence and / or the air mass flow and / or the air temperature can be varied.The sensor system of the technical unit may include a camera for observing the driver and for determining the position of the head thereof, a radar sensor for detecting body movements of the driver, contact sensors in the steering wheel and / or in the seat, sensors for detecting the body temperature of the driver and further sensors which may contribute to the assessment of the vital state of the driver. The sensor system can comprise a cloud in which, for example, the data of current ODDs are stored.The control unit, which forms the interface of the technical unit with the climate control system and preferably also between the driver assistance system and the climate control system, can comprise at least one computer unit, at least one internal and / or external memory, such as a cloud, a receiving unit for receiving the signals, at least the sensor system and a transmitting unit for transmitting signals to the climate control system. The control unit may be a central control unit of the technical unit.All features described in relation to the first aspect also apply to the second aspect, provided this yields the effect, et vice versa.A further aspect relates to a vehicle having a technical unit according to the second aspect, having a sensor system which monitors at least the driver of the vehicle, sensors for detecting an internal temperature in the vehicle and an external temperature, a warning signal generator, an automatic air conditioning system for controlling the temperature of an interior of the vehicle, and a control unit, wherein the control unit forms an interface with the automatic air conditioning system, with the result that the automatic air conditioning system automatically changes an air or cold flow if the sensor system recognizes that the driver has a concentration deficit or has fallen into sleep or is exhausted and does not react within a predefined or predefinable reaction time in the event of a level change in the case of automated driving. The technical unit is configured to execute the method according to the first aspect.An exemplary embodiment of the method and of the technical unit is explained in more detail below with reference to a respective figure. The figures show in detail: FIG. 1 shows a sketch of the method; FIG. 2 : shows a schematic illustration of the technical unit; FIG. 3 : shows a method profile over time beam.FIG. 1 shows an exemplary embodiment of the method according to the first aspect on the basis of a sketch. The reference numerals used in the description for better understanding, which do not directly relate to the method, are taken from FIGS. 2 and 3. The air or cold flow of the air blown into a vehicle interior of an ego vehicle, not shown, is focused on the driver in the exemplary embodiment, and the air temperature is additionally modified to clarify the concept of the invention. However, it is clear that the air flow can also be influenced by other parameters, such as air mass flow, injection angle, etc. The control unit 90 can be the control unit 90 of a technical system TS for automated driving, an automatic climate control system 50 or a driver assistance system FAS for observing the driver by means of the sensor system S 1, S 2, S 3.In a first method step I, the technical system TS for automated driving establishes that a change in the level at which the ego vehicle is currently moving in an automated manner is imminent. This generally means that the technical system TS changes from a current level to a lower level. At the lower level, the driver has to take more control over the ego vehicle than was required at the current or higher level. In order to safely perform this, the technical system TS specifies a return time t R within which the driver must be ready to take over the now required additional tasks, for example to control the steering wheel again manually.In order to inform the driver of the imminent level change, a warning signal is generated by the technical system TS or a technical unit 100, which can comprise the technical system TS, in a second method step II and is output in a manner perceptible to the driver in the ego vehicle. The output of the warning signal begins at the latest at a time which corresponds to the time of the level change minus the predefined return time t R for the driver. The warning signal preferably starts earlier, for example 2 seconds, 5 seconds or any other time before the said time.If the technical system TS establishes in a third method step III that the driver of the ego vehicle does not show any reaction or does not show a sufficient reaction within or after the expiration or predefined partial expiration of the predefined return time t R the automatic climate control system 50 is activated and / or preset for a later task via an interface in which the technical system TS is connected to an automatic climate control system 50 of the ego vehicle. The fact that the driver does not react or does not react appropriately can be determined, for example, by a driver assistance system FAS of the technical unit 100.If the driver responds to the first warning signal within the predefined return time t R the method ends.If the driver does not react or does not react appropriately within the predefined return time t R of the ego vehicle, the driver is actively blown by the climate control system 50 in a fourth method step IV after expiration or at least predefined partial expiration of the predefined return time t R. In order to maximize the effect of the blowing, the climate control system 50 can be focused on the driver of the ego vehicle in the fourth method step IV.If the driver of the ego vehicle now reacts in a manner expected by the technical system TS, for example, it again assumes control over the steering wheel, the method ends in a fifth method step V. That is, the blowing on of the driver and the focusing of the automatic climate control system 50 on the driver are returned. The climate control system 50 is no longer connected to the technical system TS in the interface. If this goal is not reached, in the fifth method step V the ego vehicle is stopped and possibly secured by the or a driver assistance system FAS. Furthermore, an emergency call can be sent automatically.FIG. 2 shows a diagrammatic illustration of a technical unit 100 which substantially comprises a technical system TS, a driver assistance system FAS, an automatic climate control system 50 and a control unit 90. The control unit 90 can be comprised by the technical system TS, the driver assistance system FAS or the climate control system 50. In the exemplary embodiment, this is a separate control unit 90, which is connected via a line L 1 to the technical system TS and via a line L 2 to the climate control system 50. The technical system TS can have its own control unit or be connected to the control unit 90 via a line L 3 (dash-dot line).The control unit 90 forms an interface in which the technical system TS and the climate control system 50 can be connected to one another when the technical system TS is active, which means that the ego vehicle is driving in an automated manner.The driver assistance system FAS is connected to the sensors S 1, S 2 and S 3 with which the driver of the ego vehicle can be observed. The driver's observation may be used to determine whether the driver is fit and sufficiently concentrated, or conscious, health-related, or not sufficiently comfortable or distracted due to stress or fatigue.The climate control system 50 is connected to a sensor 4 that measures a temperature in the passenger compartment of the ego vehicle and a sensor 5 that measures an external temperature. The climate control system 50 can be connected to further sensors, for example for determining the air humidity inside and / or outside the ego vehicle.The control unit 90 shown in the exemplary embodiment comprises a receiving unit 20 for receiving the signals of the sensors S 1, S 2, S 3; S 4, S 5, a computer unit 40 for the driver assistance system FAS and / or the technical system TS and the automatic climate control system 50, an internal memory 30 and a transmitting unit 10, respectively. The receiving unit 20 can also receive signals of the technical system TS, the automatic climate control system 50 and the driver assistance system FAS. The computer unit 40 for processing the signals of the technical system TS and the computer unit 40 for processing the signals of the automatic climate control system 50 are connected to one another, for example, via a data bus and together form the computer unit 40 for the technical unit 100.The sensors S 1, S 2, S 3 can comprise, for example, a camera, a radar sensor, a vitality sensor, such as a pulse meter or a fever detection sensor, or a contact sensor, for example in the steering wheel. The data recorded by the sensors S 1, S 2, S 3 are transmitted to a computer unit 40 of the control unit 90. A program with an algorithm runs on the computer unit 40, which can determine an acute illness, wake-up, depletion or distraction of the driver from the transmitted data.If, for example, a failure of the driver is determined by the computer unit 40, the technical system TS or the driver assistance system FAS or the control unit 90 can activate a warning signal generator 60, which generates at least one warning signal or a sequence of warning signals in order to wake up the driver or to increase the attention level thereof. The sequence of warning signals can comprise, for example, an acoustic signal 61, such as a warning tone or a warning tone sequence with a changing volume, a haptic signal 62, such as a brake jerk, a sudden tensioning of the seat belt or a vibration of the steering wheel, and / or an optical signal 63, such as a one-time or repeated (disco effect) change in the color of the interior lighting or a flashing warning sign on an optical output device, such as the head-up display.If the driver responds to the warning signal or signals until a predefined time t 1( all reference signs for temperature and time from FIG. 3 ), the method stops. If the driver does not react or at least does not react sufficiently until the time t 1 the output of the warning signals is continued and at the same time the technical system TS activates the air conditioning system 50 via the control unit 90 or initiates a presetting of the air conditioning system 50. From the "standby mode", the air conditioning system 50 can be activated at a later time in order to blow on the driver of the ego vehicle. For this purpose, the climate control system can be focused on the driver by closing, for example, all air vents 51, 52, 53 of the climate control system that are not directed at the driver of the ego vehicle. In addition, a current temperature T a of the air blown to the driver of the subject vehicle may be tempered to a calculated target temperature T z. The target temperature T z can be calculated, for example, by the computer unit 40, on which a program runs using a corresponding algorithm, from an internal temperature in the passenger compartment of the ego vehicle measured using the sensor S 4 and an external temperature measured using the sensor S 5, or can be determined on the basis of the measured temperature values on the basis of a characteristic map stored in the memory 30 of the control unit 90 or an external memory 35, such as a cloud. The time required for the air conditioning system 50 to cool the air to the target temperature T z can likewise be calculated or taken from a characteristic diagram which is stored, for example, in the memory 30 of the control unit 90 or in the external memory 35, for example a cloud to which the control unit 90 has access.The technical system TS stores a time t 2 at which the automatic climate control system 50 is switched to the warning signals when it is reached and begins to blow the air, which is temperature-controlled to the target temperature T z to the driver via air vents 51, 52, 53. By simple subtraction of the determined time which the climate control system 50 requires to reach the target temperature T z from the time t 2, it is possible to determine the time t 1.1 at which the climate control system 50 has to be activated, for example, by the control unit 90 so that it can act on the driver at the time t 2 immediately in addition to the other warning signals with the temperature-controlled air with the target temperature T z. The direction, the air quantity and the flow speed of the air can be adjusted via the air vents 51, 52, 53 such that the air strikes the face, the neck or the eye portion of the driver directly.FIG. 3 shows the course of the temperature T in ° C. over time t. The starting point is an initial temperature T a, for example 20° C., which is to be tempered to the target temperature T z, for example 10° C. The time t 1 is drawn on the time arrow until the driver has to have reacted in order to stop the method. Furthermore, the time t 2 is indicated, at which the air is temperature-controlled by the climate control system 50 to the target temperature T z in order to be able to be blown into the passenger compartment or onto the driver at the target temperature t Z respectively. The determined time required by the air conditioning system 50 to correspondingly temperature control the air is denoted by tΔ50. As can be seen in the example of FIG. 3, a time difference Δt dif. exists between the time t 1 and the time t 1.1, at which the climate control system 50 is activated. The point in time at which the driver assistance system FAS stops and secures the ego vehicle is designated by t 3 since the driver has shown no or at least no adequate reaction to the different warning signals. In addition, the return time t R is drawn in, in the example the time period from the start of the method at the time t 0 to the time t 2, in which the air conditioning system 50 is prepared.The return time t R can, however, also be the time period from the start of the method at the time t 0 to the time t 1 or another time period.List of reference charactersI method step II method step III method step IV method step V method step 100 technical unit 10 transmitting unit 20 receiving unit 30 memory 35 external memory 40 computer unit 50 climate control system 51 air outlet 52 air outlet 53 air outlet 60 warning signal generator 61 warning signal generator 62 warning signal generator 63 warning signal generator 90 control unit FAS driver assistance system L 1 line L 2 line L 3 line S 1 sensor S 2 sensor S 3 sensor S 4 sensor S 5 sensor T temperature T a output temperature, Temperature T z target temperature t time t 0 time t 1 time t 2 time t 3 time t 1.1 time tΔ50Zeitdifferenz tΔdifZeitdifferenz t R recovery time
