Description

The invention relates to a method for operating an electronic vehicle guidance system for an at least partially autonomously operable motor vehicle, wherein at least one motor vehicle component for autonomously moving the motor vehicle is controlled by the electronic vehicle guidance system, at least during a sleep phase of a user of the motor vehicle. Furthermore, the invention relates to an electronic vehicle guidance system.

Many solutions for autonomous motor vehicles are known from the prior art. In particular, in a fully autonomous motor vehicle driver interventions are no longer necessary. In particular, during these movement phases of the motor vehicle, in other words during the autonomous driving operation of the motor vehicle, a user can then recover, whereby corresponding recovery phases differ from user to user. In particular, such recovery phases can be described by sleep phases in which the user sleeps. Both the duration of sleep and the intensity of sleep phases vary from user to user.

The DE 10 2013 012 750 A1 discloses a method for operating a driver assistance system adapted for automatic driving by intervention in the engine control, a transmission and a brake system of a motor vehicle, wherein a sleep mode is activated by a driver by controlling at least one vehicle component so as to control one comfortable rest or sleep break the driver allows.

Object of the present invention is to provide a method and an electronic vehicle guidance system, by means of which a need for a better recovery of the user can be addressed.

This object is achieved by a method and by an electronic vehicle guidance system according to the independent patent claims. Advantageous embodiments are specified in the subclaims.

One aspect of the invention relates to a method for operating an electronic vehicle guidance system for an at least partially autonomously operable motor vehicle. In the method, at least one motor vehicle component for autonomously moving the motor vehicle is controlled by means of the electronic vehicle guidance system, at least during a sleep phase of a user of the motor vehicle.

It is provided that the sleep phase is detected by means of a detection device and an actual type of sleep phase is determined by means of an electronic computing device and the at least one motor vehicle component is controlled depending on the particular type of sleep phase.

This can be addressed in an improved way to the recreational needs of the user.

In particular, for this purpose, the electronic vehicle guidance system may have an electronic computing device, by means of which a detection and determination of the sleep phase and the type of sleep phase can be performed.

As a motor vehicle component, which can be used in particular for partially autonomous operation, for example, a navigation device, brake system, an engine control or a transmission can be considered. In other words, a corresponding control or movement of the motor vehicle can be carried out by means of the electronic vehicle guidance system.

The invention is based on the knowledge that in particular different types of sleep phases exist in a user. In particular, it can then be provided that, depending on the different types of sleep phases, a different activation of the respective motor vehicle component is carried out. For example, a steering device as a motor vehicle component can be correspondingly controlled gently, should a user be in the falling asleep phase. Stronger steering can then be performed, for example, if the user is in a deep sleep phase.

According to an advantageous embodiment, a travel route of the motor vehicle is adapted to the particular type of sleep phase depending on the particular type of sleep phase. In particular, it can thus be provided that, for example, a navigation device is actuated correspondingly as a motor vehicle component. In particular, depending on the particular type of sleep phase, the travel route, for example routes with increased cornering, can be bypassed in order not to wake the user in a fall asleep. This can be addressed in an improved way to the recreational needs of the user.

Furthermore, it has proven to be advantageous if by means of the detection device at least one deep sleep phase as a type of sleep phase and / or a light sleep phase as the type of Sleeping phase is detected. In particular, for example, an eye movement observation can be carried out for this purpose so that the deep sleep phase and / or the light sleep phase can be reliably detected by means of the detection device. The detection device can be designed for example as a camera, by means of which then the deep sleep phase and / or the light sleep phase can be detected.

It has also proved to be advantageous if the detection device is an internal-vehicle detection device of the electronic vehicle guidance system and / or a mobile terminal of the user is used as detection device. As motor vehicle internal detection device, for example, a camera may be arranged in the interior of the motor vehicle, which recognizes the user or a plurality of users in the motor vehicle and monitors their sleep phase and type of sleep phase. As a mobile terminal, for example, a mobile phone or a smart watch can be used, which can also determine the sleep and the sleep of the user via appropriate sensors. In particular, a corresponding connection between the electronic vehicle guidance system and the mobile terminal can then be set up at the mobile terminal, so that the information relating to the sleep phase of the user can be transmitted. For example, this can be done by means of Bluetooth.

In a further advantageous embodiment, the recognized sleep phase and / or the specific type of sleep phase are stored in a memory device of the electronic vehicle guidance system and / or in a memory device external to the vehicle for evaluation. In particular, thus, a sleep profile can be created, so that a corresponding sleep behavior of the user can be predicted. In particular, depending on this prediction, a corresponding planning of the route, in other words a route guidance, can be carried out. Thus, the recreational needs of the user can be improved.

Yet another aspect of the invention relates to an electronic vehicle guidance system for an at least partially autonomously operable motor vehicle, wherein the electronic vehicle guidance system is designed for carrying out a method according to the preceding aspect. In particular, the method is carried out by means of the electronic vehicle guidance system.

Yet another aspect of the invention relates to a motor vehicle having an electronic vehicle guidance system. The motor vehicle is designed in particular as a passenger car.

Advantageous embodiments of the method are to be regarded as advantageous embodiments of the electronic vehicle guidance system and of the motor vehicle. For this purpose, the electronic vehicle guidance system and the motor vehicle have representational features which make it possible to carry out the method or advantageous embodiments thereof.

Further advantages, features and details of the invention will become apparent from the following description of a preferred embodiment and from the drawing. The features and feature combinations mentioned above in the description as well as the features and feature combinations mentioned below in the figure description and / or alone in the single figure can be used not only in the respectively indicated combination but also in other combinations or alone, without the frame to leave the invention.

The single FIGURE shows a schematic side view of a motor vehicle with an embodiment of an electronic vehicle guidance system. In the figure, identical or functionally identical elements are provided with the same reference numerals.

The FIGURE shows a schematic side view of a motor vehicle 10 with an embodiment of an electronic vehicle guidance system 12 , The car 10 is designed for at least partially autonomous operation. In particular, the motor vehicle 10 trained as a passenger car. It is during a sleep phase of a user 14 . 16 of the motor vehicle 10 at least one motor vehicle component eighteen . 20 for autonomously moving the motor vehicle 10 by means of the electronic vehicle guidance system 12 controlled.

It is provided that by means of a detection device 22 . 24 the sleeping phase is detected and by means of an electronic computing device 26 . 28 a current type of sleep phase is determined and depending on the particular type of sleep phase the at least one motor vehicle component eighteen . 20 controlled.

The figure shows in particular that in the motor vehicle 10 two users 14 . 16 sit. A first user 14 and a second user 16 are in the vehicle 10 , By means of a first detection device 22 which are in an interior 30 of the motor vehicle 10 can be arranged, the sleeping phase of the first user 14 and the second user 16 be recognized. Furthermore, can be provided that in this embodiment, the first user 14 a second detection device 24 which can be designed in particular as a mobile terminal, for example as a mobile phone or smart watch. In particular, the sleeping phase can likewise be determined by means of the mobile telephone or by means of the intelligent clock via, for example, the detection of a pulse beat. The first detection device 22 is designed in particular as a camera and can in particular eye movements of the user 14 . 16 capture, thereby affecting the sleep phase of the user 14 . 16 can be closed.

A first electronic computing device 26 may be formed inside the vehicle and a second electronic computing device 28 may be formed outside the vehicle. In particular, for this purpose, the vehicle-internal electronic computing device 26 an in-vehicle storage device 32 have, by means of which the recognized sleep phase and / or the particular type of sleep phase can be stored. The vehicle-external electronic computing device 28 can also have a storage device 34 have, which is designed outside the vehicle and also store the sleep phase and / or the specific type of sleep phase.

Furthermore, it can be provided, in particular, that depending on the particular type of sleep phase, a driving route 36 of the motor vehicle 10 adapted to the particular type of sleep phase.

Furthermore, it can be provided that by means of the detection device 22 . 24 at least one deep sleep phase is recognized as the type of sleep phase and / or a light sleep phase as the type of sleep phase.

By means of the autonomous motor vehicle 10 can respond to the recreational needs of users 14 . 16 be better track-and traffic-dependent received by the respective properties in the motor vehicle 10 and / or on, for example, an Internet backend, which in the present embodiment as a motor vehicle external electronic computing device 28 is formed, are known. When sleeping in the vehicle 10 It should be noted that the driving operation of the motor vehicle 10 should be dependent on the individual sleep phases, for example, cautious driving in a fall asleep, offensive driving depending on deep sleep phases. In addition to the driving operation are also the route selection and the route 36 a navigation system 20 influences what goes beyond the stated rest mode.

It may be provided for this purpose that a recovery and traffic phase-dependent route choice of the autonomous motor vehicle 10 is carried out, wherein the motor vehicle 10 is in autonomous driving and the detection device 22 . 24 the stages of individual users 14 . 16 can measure or they are known. For this purpose, further, the motor vehicle 10 even with the motor vehicle external electronic computing device 28 be coupled.

The autonomous motor vehicle 10 , in particular the electronic vehicle guidance system 12 , then can route guidance of the route 36 and adjust a route selection to the sleep stages, ie the type of sleep phase. Furthermore, the electronic vehicle guidance system 12 the route 36 be taken into account in the expected traffic phases, such as the free traffic, synchronized traffic or moving wide traffic jam. For this purpose, for example, a synchronized traffic on a highway can be classified as particularly favorable in weaker sleep phases in order to prevent awakening. Respectively, in a fall asleep a moving wide jam may be unfavorable due to many deceleration and acceleration events from the vehicle standstill. Free traffic or speed limit are rather unfavorable for the Einschlafphase due to the lane change operations and an irregular driving operation.

In the in-vehicle electronic computing device 26 and / or in the motor vehicle external electronic computing device 28 can be knowledgeable about the individual sleep cycles and sleep stages of the users 14 . 16 be collected and forecasted. Furthermore, the current traffic phases can also be available there and predicted. It can then be provided that a route guidance takes into account the static properties of the roads in connection with the expected sleep stages. The route guidance should be the least overlap between winding routes with awake or light sleep times of all users 14 . 16 enable. Furthermore, the route guidance should allow the greatest possible overlap between winding roads and deep sleep REM sleep phases. Furthermore, the route guidance should be improved in such a way that the slightest overlap between the user's wake-up or light sleep times 14 . 16 arise with moving wide traffic jams, since the constant starting and braking could be distracting.

Furthermore, the route guidance could be improved in such a way that the greatest overlaps between the deep sleep REM sleep phases and the traffic phase are more moving result in a wide traffic jam. Accidents or closures, so-called Megajams, should be as strong as possible with waking phases or light sleep times of the users 14 . 16 overlap, since the motor vehicle 10 usually resting frequently with many short start-up and braking maneuvers.

Furthermore, it can be provided that route selection avoids routes with changes of illumination, for example towns or cities, depending on the sleep phases in order to be able to achieve maximum uniformity with light and noise as well. The routes may also be adapted to avoid areas with traffic lights, particularly urban areas, and, for example, left turns with frequent stopping and braking maneuvers. In particular, this can also be the knowledge of the individual sleep cycles and sleep needs of the user 14 . 16 stored.

It is also possible that learning or input of requirements for healthy sleep with a high degree of inter-individual, but also intra-individual variability between users 14 . 16 is possible. It can also be the input of parameters, such as the duration of sleep, earliest awakening, watching the sleep phases of the user 14 . 16 , be performed.

The route selection can also be aligned to the maximum recovery time of arrival, for example, possibly a route change, or possibly slow driving in a fall asleep and speedy driving in a deep sleep phase, while curvy sections are selected only in a deep sleep phase. The route selection may also be subject to a uniform as possible to be traveled route to prevent waking up by, for example, curvy stretches, gradients and bad roads.

Furthermore, when driving a avoidance of stronger acceleration and braking during certain recovery phases can be considered. Furthermore, the awakening can be carried out in a favorable phase during sleep with maximum recovery, which can be done, for example, by accepting a longer distance. Furthermore, tank or loading operations during the recovery phase can be avoided as possible and tailored to the recreational needs. Furthermore, a tank or charging process should be unavoidable during the recovery periods, so a user can 14 . 16 be awakened in dependence in a sleep phase for this most favorable. Furthermore, before the start of a recovery phase, the user 14 . 16 be asked to refuel or to charge, if refueling or loading would be necessary during the recovery phase. As a result, tank and loading processes can be tuned to predictable, in particular cyclical, sleep phases.

Furthermore, it can be provided that the vehicle-external electronic computing device 28 the respective recovery requirements of the users 14 . 16 can save and evaluate. These can then be used as individual sleep profiles in the motor vehicle 10 be displayed and processed. Furthermore, users can 14 . 16 the respective journey and proposed route 36 Select and confirm with the desired recovery phase. Furthermore, the user can 14 . 16 after a recovery period from the motor vehicle 10 be asked to provide a rating to indicate how restorative sleep was. Furthermore, it can be provided that the evaluations to the vehicle-external electronic computing device 28 be transferred and evaluated and can lead to future trips to optimize the autonomous driving behavior or the route choice, in which case the motor vehicle 10 the fatigue of the users 14 . 16 and accordingly recommendations for resting periods including their duration vis-à-vis the users 14 . 16 can pronounce. In other words, thus, a kind of individual idle-phase recommendation service can be provided. Furthermore, the navigation system can also 20 various recovery and traffic phase optimized routes to the user 14 . 16 to suggest for selection.

Overall, the invention shows a method for recovery and traffic phase dependent route selection autonomous vehicles 10 ,
