Description

The invention relates to a method for operating an at least partially autonomously operable motor vehicle. A characteristic characterizing an occupant of the motor vehicle is detected by means of at least one detection device of an electronic vehicle guidance system of the motor vehicle. An occupant condition based on the detected characterizing property of the occupant is evaluated by means of an electronic computing device of the electronic vehicle guidance system. Furthermore, the invention relates to a motor vehicle.

The following interest is directed in particular to the field of navigation / kinematics in motor vehicle construction and in particular to an autonomous driving operation for motor vehicles. In particular, it may happen in the prior art that the ride for the occupant is perceived as unpleasant and stressful, as for example, the driver puts on a different driving behavior than the occupant himself would do. In particular, in an autonomous driving of the motor vehicle, this could also interfere. Likewise, the own individual condition of the occupant can lead to a different driving style when driving himself.

The DE 10 2016 215 251 A1 relates to a method for operating a navigation device of a motor vehicle. A travel route of the motor vehicle described by a travel plan is provided. User-specific status data correlating with a physical condition of the user is received, and an index value is determined from the user-specific status data, wherein the index value describes a comparison value of a physical well-being of the user. It is performed by a processing unit providing and operating a digital model based on the index value or based on multiple index values a future index value of the user depending on the course of the route and the surrounding data, the at least one current property of an environment of the motor vehicle and / or at least describe an expected property of a future environment of the motor vehicle in a course of the driving route predicts. Depending on the predicted, future index value, a change of the travel plan and in accordance with the changed travel plan a control of the navigation device is performed.

The object of the present invention is to provide a method and a motor vehicle by means of which an individual operation of the motor vehicle tailored to the occupants is made possible.

This object is achieved by a method and by a motor vehicle 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 at least partially autonomously operable motor vehicle. A characteristic characterizing an occupant of the motor vehicle is detected by means of at least one detection device of an electronic vehicle guidance system of the motor vehicle. An occupant condition based on the detected characterizing property of the occupant is evaluated by means of an electronic computing device of the electronic vehicle guidance system.

It is provided that at least one operating parameter of the electronic vehicle guidance system of the motor vehicle is adapted for the fully autonomous operation of the motor vehicle as a function of the evaluated occupant condition by means of the electronic computing device. The motor vehicle is operated fully autonomously as a function of the at least one adapted operating parameter of the electronic vehicle guidance system.

This makes it possible in particular for an occupant to be able to distinguish a pleasant one from an unpleasant trip. In particular, it can thus be adapted to the occupants, depending on the situation as well as on the character of the characteristic, as it is perceived to be pleasant for the occupant. In particular, this may be Tageszeit- / Gemüts- / traffic and health-related.

In particular, this makes it possible to provide a fully autonomous driving operation of the motor vehicle perceived as pleasant for the occupant. Thus, the fully autonomous operation of the motor vehicle can be provided individually adapted to the occupants.

In particular, a method for driver-state-dependent automatic driving is thus generated. For example, the motor vehicle may have location information, for example via a position detection device, for example via a global navigation positioning system (GPS), and a communication device, and a corresponding navigation system. In particular, the detection of the characterizing property of the occupant, in particular the occupant condition, can then be carried out by means of the detection device. In particular, then depending on the characterizing property of autonomous driving be performed. In particular, in each autonomous drive of the motor vehicle, the respective driver state / occupant state is taken into account. For example, a fatigue expert can provide, for example, a leisurely, slow way of driving if positively recognized. It can also be provided that the age, gender and driving experience of the driver / occupant are recognized and taken into account. Furthermore, it can be provided that a health expert (Fit and Healthy) recognizes certain parameters of the driver and derives therefrom a manner of automatic driving operation. For this purpose, for example, a body temperature and / or a pulse of the occupant can be taken into account. For example, an anxiety of the driver / occupant can be determined or specified, thereby preventing, for example, an autonomous drive through bottlenecks / tunnels.

Thus, various combinations of driver state and traffic condition-dependent operating parameters of the autonomous driving operation are made possible. For example, depending on the characterizing characteristic of the occupant, an overtaking maneuver in the synchronized traffic can be prevented with careful driving. Likewise, for example, a dense opening in free traffic with careful driving can also be prevented. In particular, an exploitation of the legally permitted framework in case of haste and target dates can be carried out. It is also possible that, for example, a longer route with avoidance of deceleration / acceleration operations against a city route with many traffic lights is selected in the goal of a leisurely drive. Furthermore, it can be provided, for example, that a lane change for a turning operation is carried out as an operating parameter at an early stage and / or only shortly before the turning maneuver.

Furthermore, it can be provided that the present driver / occupant states or the characterizing properties of the driver or of the occupant are stored and evaluated by means of the electronic vehicle guidance system, which states have occurred and at which locations at which times. These stored states can then be stored on the vehicle side and / or in a corresponding backend (motor vehicle external storage device) or a cloud. Based on this, suggestions for the respective autonomous driving style or for autonomous driving operation can be given. It may further be provided that, for example, an average profile over a plurality of rides / drivers / occupants is determined on the server side as a driving style that is appropriate for the driver on average.

In particular, it can be provided that the autonomous driving operation can also be managed in personalized manner as a chauffeur driving style and can be stored in the sense of individual "avatar" occupants. For example, the corresponding chauffeur driving style can then be exchanged with other drivers via a corresponding mobile radio application or via a website.

Preferably, it can be provided that the driver / occupant can deliver a rating during and / or after an autonomous drive of the motor vehicle and this together with the driver state and the traffic condition can lead to an adaptation of the driving style parameters in a future journey.

According to an advantageous embodiment, an acceleration setting of a longitudinal acceleration device of the electronic vehicle guidance system and / or a lateral acceleration device of the electronic vehicle guidance system can be adapted as an operating parameter. In particular, corresponding acceleration parameters for the longitudinal acceleration device and / or for the transverse acceleration device can then be set. The transverse acceleration device may in particular be a steering device. In other words, cornering can be adapted by means of the lateral acceleration device. In particular, this makes it possible that depending on the characterizing property of the occupant or depending on the occupant condition corresponding acceleration and braking parameters can be set individually. This allows an individual autonomous driving operation of the motor vehicle.

It has furthermore proven to be advantageous if the characterizing property of the occupant is detected by means of an optical detection device, in particular by means of a camera, of the motor vehicle. In addition to the camera, other sensors for monitoring the occupant are possible. In particular, it is made possible by the optical detection device that the characterizing property of the occupant or the occupant state can be reliably detected. By way of example, the state of the occupant can then be reliably determined by means of image processing. Depending on the evaluation of the occupant condition, the autonomous driving operation of the motor vehicle can then be adapted accordingly.

In a further advantageous embodiment, by means of an input device of the motor vehicle, a further characterizing property of the occupant can be detected by entering the occupant. In particular, then the occupant the possibility of entering the individual occupant condition. In other words, it may be an active occupant input. For example, the occupant can enter, should he / she have an alcoholized state, enter this, and so, for example, a defensive driving style is desired. Furthermore, it can be provided that, after the entry of a corresponding degree of alcoholization, a correspondingly cautious, fully autonomous ride is provided, with, for example, a low speed in the curves. Furthermore, a predetermined driving style, in particular a chauffeur driving style, can be selected via the input device. It can also be provided that the preset chauffeur driving styles can be recorded and modified by the driver / occupant and can be adapted individually with regard to, for example, acceleration and braking behavior, lane change behavior, behavior during turning and at traffic lights. Furthermore, it can be provided that the driver / occupant can also inform the autonomous vehicle via acoustic input in which way the drive should be carried out. For example, the acoustic input of the input device can then be carried out via corresponding voice commands. Furthermore, the acoustic input can be linked to certain driving styles.

It is likewise advantageous if a navigation device of the electronic vehicle guidance system detects a current position of the motor vehicle by means of a position detection device and adopts a driving route of the motor vehicle as operating parameter of the electronic vehicle guidance system depending on the current position and on the evaluated occupant state. For example, if the inmate wants to avoid city traffic, then the route can be planned accordingly extra-urban. Also, for example, it can be prevented that no highways are used, should the occupant want to avoid high speeds. In particular, this makes it possible for the driving route to be determined or adapted accordingly, depending on the current position and on the characterizing property of the occupant. Thus, the driving route for the autonomous driving operation of the motor vehicle can be determined individually adapted to the needs of the occupant.

A further aspect of the invention relates to a motor vehicle having an electronic vehicle guidance system, which has at least one detection device and one electronic computing device, wherein the electronic vehicle guidance system is designed to carry out the method according to the preceding aspect. The motor vehicle is designed in particular as a passenger car.

The desire of the inmate 26 It could be as in his particular situation to be driven as it each as pleasant for the occupant 26 is perceived. In particular, this may be Tageszeit- / Gemüts- / traffic and health-related. In particular, then a successful autonomous driving operation of the motor vehicle 10 certainly depend on the fact that the autonomous ride is perceived as pleasant.
