Description

The invention relates to a method for individually adapting interior-related settings of a vehicle, with an interior, at least one driver located in it and a condition of the driver being detected using detected signals from an interior sensor system.

From the WO 2007011060 A1 a device for changing a mental state of a driver of a vehicle, which corresponds to an operating state of an assistance system, is known. The device controls aroma emission by air conditioner control, 1/f dither sound output by audio control, and decorative color change by display control and lighting control, to thereby regulate a driving atmosphere in the vehicle. During a driving operation, the driving atmosphere in the vehicle is controlled to an environment for waking up the driver, and during an automatic driving operation, the driving environment in the vehicle is controlled to an environment for relaxing the driver easily.

In addition, the CN 112141026A an intelligent system for adjusting a driving atmosphere. The system includes a first data acquisition module, a second data acquisition module, an analysis and processing module and an execution module, wherein the first data acquisition module is designed to obtain body data of a driver, i.e. a breathing rate, a heart rate, a body posture and a facial expression. The second data acquisition module is designed to receive vehicle data, ie vehicle movement data and/or vehicle posture data and/or driving atmosphere data. The analysis and processing module is designed to determine a driver's mental state and a vehicle state based on the driver's body data and the vehicle data and to generate a control signal for triggering a driving atmosphere adjustment based on the driver's mental state, and the execution module is designed to adjust the driving atmosphere based on the control signal.

The invention is based on the object of specifying a method for the individual adjustment of interior-related settings of a vehicle.

The object is achieved according to the invention by a method which has the features specified in claim 1.

Advantageous configurations of the invention are the subject matter of the dependent claims.

A method for individually adapting interior-related settings of a vehicle provides that an interior, at least one driver located in it, and a driver's condition are detected using detected signals from an interior sensor system. According to the invention, the detected signals are combined as a set of information. A vehicle signal unit determines information from on-board measuring instruments and other information from at least one data processing unit of the driver coupled to the vehicle, and the amount of information, the information determined and the additional information determined are fed to a detection unit, with it then being determined which form of work the driver is doing. Depending on this ascertained form of work of the driver, actuators for adjusting the interior-related settings are controlled by means of a vehicle-side regulation/control unit.

In particular, a driver of the vehicle, which is operated in automated, in particular autonomous driving mode, is automatically supported mentally during his employment, ie his productive work, when using the method. By using the method, the settings in the vehicle are optimally adjusted in relation to the driver's activity, so that an increase in productivity of the activity carried out is possible.

Exemplary embodiments of the invention are explained in more detail below with reference to drawings.

show:

• 1 schematically a vehicle with a device for carrying out a method for the individual adjustment of interior-related settings,
• 2 schematically the device for carrying out the method and
• 3 a schematic of the procedure.

Corresponding parts are provided with the same reference symbols in all figures.

1 shows a vehicle 1 with a driver 2 and with a device for carrying out a method for the individual adjustment of interior-related settings, the device in 2 shown without vehicle 1 and without driver 2.

The device has an interior sensor system 3, at least one physiological sensor not shown in detail, which can be part of the interior sensor system 3, a vehicle signal unit 4, a detection unit 5, a regulation/control unit 6 and a number of actuators 7.1 to 7.n.

The vehicle 1 has an assistance system (not shown) for automated driving. The higher an SAE level 3, 4, 5 of the automated, in particular autonomous, driving operation, the greater the possibilities for the driver 2 of the vehicle 1 to pursue other activities during the autonomous driving operation. For example, the driver 2 has the opportunity to carry out productive work during the autonomous driving operation, since the vehicle 1 takes over a driving task of the vehicle 1 in its entirety.

However, an interior of the vehicle 1 does not necessarily provide an environment conducive to performing productive work.

The method described below provides a way of adapting the interior in a targeted and automated manner to the needs of the driver 2 during his productive work, in particular with regard to an increase in productivity. The driver 2 of the vehicle 1 is mentally supported.

The device for carrying out the method has the interior sensor system 3 with a plurality of sensors 3.1 to 3.n which are designed as camera sensors and/or acoustic sensors.

Visual features in the interior of vehicle 1 can be detected on the basis of detected signals from sensors 3.1 to 3.n designed as camera sensors. For example, existing and visually automatically detectable objects and their properties, lighting conditions in the vehicle 1 and optically detectable properties of the driver 2, for example his line of sight, posture, movements, etc. are detected using the signals detected by the camera sensors.

Acoustic signals from sensors 3.1 to 3.n of interior sensor system 3 designed as acoustic sensors include, for example, noises from objects in vehicle 1, noises caused by driver 2, such as clearing his throat, yawning, sighing, spoken utterances, etc.

Signals in the form of so-called bio-signals are recorded by means of the physiological sensors, which are not shown in detail, and can be used to determine a pulse, a body temperature, brain waves, a skin resistance, among other things.

These signals from the interior sensor system 3 and the physiological sensors are combined as information set A.

In addition, the device has on-board measuring instruments, not shown in detail, which are arranged in the vehicle 1 as detection units and/or interfaces, for example an infotainment system.

For example, a carbon dioxide content of the air in the interior of vehicle 1 is determined using detected signals from an air sensor system, and an interior temperature of vehicle 1 is detected using an interior thermometer.

Signals detected by the measuring instruments are summarized as information 11 .

Using a data processing unit connected to the vehicle 1 via an interface, for example a smartphone, a tablet, a laptop, a wearable, etc., data is recorded as further information 12, for example calendar entries by the driver 2 for saved appointments in a respective period.

Likewise, an activity in relation to a telephone call made and possibly data determined using a stored telephone book about the telephone call made and the participants in the telephone call are determined as further information 12 .

Furthermore, as further information 12, it is determined which interactions and functions are currently being carried out and used by the driver 2. This includes, for example, the use of work-related function modules, such as software products in the form of spreadsheets, creativity-enhancing whiteboard brainstorming application programs, etc.

In one possible embodiment, a frequency, a duration and/or a frequency of inputs by the driver 2 such as controls, touch inputs, voice inputs, for example on a tablet and/or keyboard inputs and mouse clicks on a laptop, either by tapping input signals via a respective interface, acoustically by recognizing a vibration during touch interactions, so-called touch interactions, mouse clicks and/or keyboard operations and/or voice inputs and/or based on detected signals of the interior sensor system 3 in relation to observations Gene a hand movement of the driver 2 and input elements determined.

In a further possible embodiment, it is provided that data on the work of the driver 2 is determined as further information 12 by application programs and/or services by other equipment of the driver 2, in particular a data processing unit, for example another smartphone, smart glasses and/or wearables.

It is also conceivable that the driver 2 makes an input, for example whether he is currently working more analytically, creatively or analytically and creatively.

In addition, speech information can be analyzed, for example conducting a business telephone call or conversation in the vehicle 1 being analyzed using computer linguistics (CL) methods and/or linguistic data processing (LDV).

The ascertained information 11 and the ascertained further information 12 are fed to the vehicle signal unit 4 and combined.

The signals recorded using interior sensor system 3 and the physiological sensors and combined as information set A, the information 11 determined using the measuring instruments and, in particular, additional information 12 determined using the at least one data processing unit are combined in a detection unit 5 of vehicle 1.

An assignment is carried out by means of the detection unit 5, with it being determined which type of work is involved in the activity carried out by the driver 2.

For this purpose, a total of the information set A, the information 11 and the further information 12 can be used to validate whether the recognized work form corresponds to a “work style” or work mode desired by the driver 2 .

A number of actuators 7.1 to 7.n for individual adjustment of interior-related settings are controlled by means of regulation/control unit 6 coupled to detection unit 5 and actuators 7.1 to 7.n, based on the type of work of driver 2 determined by detection unit 5. The settings assigned to the respective form of work are divided into at least two blocks B1, B2 in order to optimize, ie to increase, work productivity.

For example, actuators 7.1 to 7.n are activated to control the lighting conditions in the interior of vehicle 1. Here, in particular, a brightness, a lumen intensity, etc. is adjusted according to the working form determined.

In addition, air conditioning in vehicle 1 is adjusted by actuating actuators 7.1 to 7.n. For example, a temperature value is reduced or increased, a carbon dioxide content is changed, etc.

In a development of the method, a representation of an interior roof is controlled by means of physical conditions, for example by opening or closing a convertible top. A simulation can also be started, with a display unit simulating a change in the height of the interior sky, for example.

A further embodiment provides that pedals of a vehicle pedal set and/or a steering wheel are controlled by a driving function in such a way that motor activities of the driver 2 are activated.

Seat settings can be changed by controlling appropriate actuators 7.1 to 7.n, for example to enable a change between a seated activity and an approximately upright/standing activity for the driver 2 doing his job.

Furthermore, acoustic signals are controlled in order to play back 40 Hz acoustic binaural signals, for example, and/or to simulate background noise that may be stimulating.

The following example situation is intended to illustrate the procedure. The consequences for the working method listed are based on findings from neurobiology.

Using detected signals from a sensor 3.1 of the interior sensor system 3, it is recognized that the driver 2 is currently interacting with his hands and is focused on a comparatively small area in his field of vision.

Based on the use of the data processing unit of the driver 2, it is determined that he is currently working, for example with spreadsheet software, in which mathematical character strings in particular are present.

The detection unit 5 then assigns a relatively strong analytical work form to this present situation. Based on this assignment, the regulation/control unit 6 controls actuators 7.1 to 7.n so that a panoramic roof of the vehicle 1 is darkened, in particular for a visual reduction in the ceiling height of the interior sky for the neurological benefit of analytical work.

Actuators 7.1 to 7.n of the vehicle pedals are activated so that the pedals can be used for motor activity in order to increase driver 2's concentration.

In addition, a lumen intensity in the interior of the vehicle 1 is increased by means of a corresponding control in order to increase concentration. Furthermore, possible interference signals are reduced.

The following additional example situation is intended to illustrate the procedure.

Using detected signals from at least one sensor 3.1 to 3.n of the interior sensor system 3, it is determined that the driver 2 of the vehicle 1 looks around comparatively a lot, moves a lot and his line of sight is often directed upwards.

A signal captured via an interface signals that the driver 2 is currently using software for creative brainstorming, is not on the phone or using other available media.

A current time in relation to a wake-up time of the driver 2 is also determined via the interface using transmitted values from his wearable fitness device with a sleep monitoring function.

The detection unit 5 then assigns a creative form of work to the present situation and reinforces it, since there is a suitable time for creative activities according to a 24-hour circadian rhythm. By appropriate activation, the regulation/control unit 6 causes a temperature in the interior of the vehicle 1 to be reduced by a predetermined value and, by activation of a display unit arranged on the interior ceiling of the vehicle 1, simulates a comparatively high ceiling height in order to simulate a so-called cathedral effect. These individual settings serve to promote the driver's 2 creativity when carrying out his current occupation.

An output of a suggestion to take a break is also prompted by the regulation/control unit 6 in order not to interrupt a so-called creativity flow of the driver 2 because of the circadian rhythm.

The following additional example situation is intended to illustrate the procedure.

If it is determined on the basis of detected signals from at least one sensor 3.1 to 3.n of the interior sensor system 3 of the vehicle 1 that the driver 2 is holding a notebook in his hands and a signal from an interface in the vehicle 1 indicates that the driver 2 is making an active telephone call and that a work-related appointment has been entered in the driver's 2 calendar, the detection unit 5 assigns a language-focused form of work to the current situation. The regulation/control unit 6 then reduces an activity of the actuators 7.1 to 7.n, which carry out a motor activity, since these can have a negative neurological effect on the speech ability of the driver 2.

If it is determined on the basis of detected signals from the interior sensor system 3 that the driver 2 is interacting with a handheld game console, the detection unit 5 does not assign any form of work to this activity by the driver 2, so that it is not necessary to activate actuators 7.1 to 7.n intended to increase productivity .

Another possible embodiment of the method provides that the device for carrying out the method can be personalized. This makes it possible for the regulation/control unit 6 to be able to be specified using determined data from the detection unit 5 and to control the actuators 7.1 to 7.n on the basis of a driver-specific behavior.

It is also conceivable that the method can also be used for other occupants of the vehicle 1, with the controlled actuators 7.1 to 7.n being assigned individually as required.

Furthermore, it can be provided that a moment when the driving task is handed over to the driver 2 of the vehicle 1 is optimized if it is recognized or determined that the driver 2 is currently in a highly productive phase with regard to his work.

a in 3 The sequence of the method shown begins with Start S and ends with Stop St, with decisions to be made being marked with an N and a Yes with a J.

In a first step S1, the driver 2 and/or another occupant of the Vehicle 1 related signals of the interior sensors 3 and the vehicle signal unit 4 tapped.

In a second method step S2, these signals are used to identify whether the driver 2 and/or the other occupant are working productively.

If it is not recognized in the second method step S2 that the driver 2 and/or the other occupant is/are working, the method jumps to Stop St.

If, on the other hand, it is recognized that the driver 2 and/or the other occupant are working in the autonomous driving mode of the vehicle 1, in a third method step S3 the detection unit 5 is used to assign which form of work the driver 2 and/or the other occupant is pursuing or is pursuing . A distinction is made here, for example, between creative, linguistic and analytical-cognitive.

Depending on the assignment of the type of work, in a fourth method step S4, a block B1, B2 of two blocks of different settings to increase productivity with regard to the work carried out by the driver 2 and/or the other occupants is selected and corresponding actuators 7.1 are activated by means of the regulation/control unit 6 driven to 7.n.

A block B1 provides, for example, increasing the ceiling height of the interior sky by opening a convertible top or sliding roof or by simulating it on a display unit etc. as a possible setting.

Another block B2 contains the settings for reducing the ceiling height by closing the convertible top or sunroof or by simulating it on a display unit. In addition, as a setting, 40 Hz acoustic binaural signals are played in order to increase the work productivity of the driver 2 and/or the other occupants.

After the end of the work or after a specified period of time has elapsed, the method jumps to Stop St and is ended for the time being, for example because the driving task has been handed over or the vehicle 1 has reached its destination.
