Description

The invention relates to a method for controlling the body movement of a vehicle according to the preamble of patent claim 1.

In vehicles, a variety of systems are available that increase the comfort and safety of the driver. So far, known systems are designed to ensure that the vehicle is in a quiet and stable condition and there remains independent of external influences. This means that any noise, movements, vibrations, etc. that the driver perceives as disturbing caused by the vehicle or systems in the vehicle are avoided or compensated. In order to avoid or compensate for such potential driver disturbances, systems are known which compensate for or eliminate as much as possible noise or motion, e.g. Systems for avoiding partial chattering in internal combustion engines. Other systems for suppressing disturbances, both comfort and safety, are chassis stabilization systems, such as those disclosed in U.S. Pat. Systems for roll stabilization or roll stabilization, systems for level control for example via air springs, systems for electronic damper control, active suspension, active steering systems for balancing or inducing yaw movements etc.

It is an object of this invention to provide a method of controlling the body motion of a vehicle using systems in the vehicle to increase ride comfort and driving enjoyment. This object is achieved by the features of the independent claims. Advantageous embodiments are the subject of the dependent claims.

Proposed is a method for controlling the body movement of a vehicle, wherein in a first step, an evaluation of media information takes place, and in a second step based on the evaluation, the corresponding vehicle system is controlled, so that a longitudinal and / or transverse and / or Vertical and / or roll and / or pitch and / or yaw movement of the body of the vehicle is generated.

Furthermore, it is provided that media information comprises: audio information comprising music played and / or film noise, and / or visual information and / or kinesthetic data that can be determined from audio-visual data and / or kinesthetic data provided in a corresponding channel. Data provided via the kinaesthetic channel are e.g. Information about which movements / accelerations around which or along which axes should take place to which extent and at what time.

It is known, for example, that head banging and / or rocking can improve the enjoyment of music and possibly also the shared experience, depending on the preferred music style. For example, visual data is a change in the camera perspective in a movie, with the corresponding data being provided for the execution of the method, either through a corresponding channel or through analysis of captured audio or visual data. Further, the LFE channel known from surround sound systems can enhance sound effects when watching movies, so that when using this information, an improvement in audio perception can be achieved. Thus, by the method, the media enjoyment, e.g. So the music and or movie enjoyment increased and a show effect can be achieved by the movement of the body.

Furthermore, it is provided that recorded media information is played music and that the music is evaluated by analyzing the beats per minute and the phase of the music. Advantageously, the movement or movements of the vehicle are generated in time with the recorded music. By adjusting the body movement to the beat of the music, enjoyment of music and show effect are increased.

It is further contemplated that captured media information is audio information provided over an LFE channel. Thus, for example, very low frequencies, including frequencies that are inaccessible to a subwoofer, transmitted as shocks to the body, so that a movie experience is enhanced.

Furthermore, it is provided that captured media information is audio-visual information that is stored in a kinaesthetic channel and made available as movement information of the medium. Thus, the movie enjoyment can also be increased by realistic (re) imitation of movements.

Furthermore, it is provided that the activation of the method is performed manually by a user or automatically based on a detection of the user and stored data and / or detected external influences. Thus, even with an empty vehicle, which will then be traveling autonomously in the rule, an effect for persons outside the vehicle can be generated.

Furthermore, it is provided that the longitudinal and / or transverse and / or vertical and / or roll and / or pitch and / or yaw movement of the body of the vehicle in a predetermined intensity and / or phase is generated.

Advantageously, the intensity and / or the phase of movement of the body independently or in combination is selected stepwise or in predetermined steps manually by the user or automatically based on a detection of the user and stored data and / or detected external influences. Thus, an individual adjustment depending on the situation and needs is possible.

Furthermore, it is provided that the intensity and / or the phase of the movement of the body depending on the detected state of the vehicle, comprising at least the vehicle, detecting a low existing lateral dynamics, and / or the detection of environmental conditions, comprising at least one detecting less Traffic density and / or sufficient space for the planned body movement, limited to a predetermined value. Advantageously, it is provided that the intensity and / or the phase of the movement of the body depending on the vehicle occupancy and / or depending on the condition of the vehicle occupant, is limited to a predetermined value.

By limiting the intensity and / or the phase of the movement of the body depending on the detected state of the vehicle, a risk to other road users and also the driver and the occupants can be avoided.

Furthermore, it is provided that the method only in a predetermined state of the vehicle, comprising at least the vehicle, detecting a low existing lateral dynamics, and / or the detection of environmental conditions, comprising at least detecting low traffic density and / or sufficient space for the planned Body movement, is activatable. Advantageously, it is provided that the method can be activated only in a predetermined state of the vehicle occupancy, comprising at least the "unoccupied" state, and / or depending on the state of the vehicle occupants.

By activating the method in only certain states, a risk to other road users and also of the driver and the occupants can be avoided.

Further, a control unit is proposed, set up for the evaluation of media information, and based on the evaluation for controlling the corresponding vehicle system, to a longitudinal and / or transverse and / or vertical and / or roll and / or pitch and / or To generate greed movement of the body of the vehicle.

Advantageously, the control unit is further configured to receive and evaluate data via acquired media information and to output signals for controlling actuators based on the evaluation. The controller may be both physically a unit, as well as divided into a plurality of units that communicate with each other and control the actuators. Advantageously, the or are used in the vehicle control units for implementing the method, since they already take over a large part of the functionality even without application or activation of the method.

The above statements on the method according to the invention according to the first aspect of the invention also apply correspondingly to the control device according to the invention according to the second aspect of the invention. At this point and in the claims not explicitly described advantageous embodiments of the control device according to the invention correspond to the above-described or described in the claims advantageous embodiments of the method according to the invention.

Preferred embodiments of the invention are explained below with reference to the accompanying drawings.

• 1 shows a schematic representation of important components for performing the method in a vehicle according to an embodiment of the present invention.
• 2 FIG. 3 shows a flowchart of the method according to an embodiment of the present invention.

The invention is based on the finding that, in principle, all technologies present in the vehicle, especially assistance systems, individually or in combination are also able or would actively cause and / or increase body movements, for example in a stationary or slowly moving vehicle with and without inmates. This insight can be used for the effect of enhancing the enjoyment of music, the enjoyment of movies and also for a show effect.

1 shows a schematic representation of important components for performing the method in a vehicle 100 , The procedure of the procedure is schematically in 2 shown.

The method and system described below is based on an application in the vehicle 100 , so for example, a car or a truck described with appropriate equipment. If the term control is used below, this may also include a regulation. The control or regulation can be effected by one or more interventions in a corresponding vehicle system, for example a driver assistance system, or individual components of the vehicle are controlled directly. The method is applicable both to in-vehicle and out-of-vehicle media information. The evaluation of the media information can include both an analysis in which captured data is converted into movement information via appropriate methods, as well as a pure evaluation in which already existing motion information is recorded and used for control.

According to one embodiment of the invention may be on the control or regulation of the longitudinal dynamics 10 , ie via drive 101 or brake 102 after activation of the function according to the invention, ie of the method, by a user 40 by the driver or an occupant based on an evaluation of captured media information 30 (Step S1) a longitudinal and / or transverse and / or vertical and / or roll and / or pitch and / or yaw movement of the body of the vehicle 100 depending on the recorded media information 30 , eg in time with the vehicle 100 played music or a film being played and kinaesthetic data determined from audio-visual information or transmitted via a corresponding channel (step S2).

It is also possible outside the vehicle 100 existing and from the vehicle 100 recorded media information 30 such as using music to customize the body movement. This can advantageously be used when the vehicle is traveling autonomously and empty, ie there are no occupants, which corresponds to the state "unloaded". Then, a show effect for off-vehicle persons may be generated by off-vehicle music, audio-visual information, or other media information adapted body movements.

In order to produce a suitably adapted body movement, in the event that as a media information 30 a recorded music is detected, the rhythm of the music played in a corresponding device 11 evaluated or analyzed (step S1), wherein preferably the so-called beats-per-minute bpm, so the beats per minute, and the phase are used. The analysis of the rhythm of the music is similar to that of known light organs. In this case, the fed-in sound signal is split into frequency bands and the time-dependent signal profile is examined, for which purpose, for example, Fourier transformations can be used. Based on the analysis of the music, the drive train and / or the braking function are controlled so that, for example, a common-mode longitudinal jolting or a longitudinal movement of the vehicle 100 in phase with the beat or rhythm of the music.

In doing so, users can 40 For example, the driver or other occupants of the vehicle after appropriate release, for example by the driver, manually select the strength or intensity and / or the phase of the body movement. In the case of music as media information 30 is present, the clock and thus the effect, ie the longitudinal movement or the longitudinal pressure and / or roll and / or pitch and / or yaw movements and / or vertical movements of the vehicle can be adjusted. Alternatively, the movements can be set via default settings, eg when the vehicle 100 autonomously driving without occupants, ie traveling in the "unloaded" state, eg to carry out delivery trips or trips to pick up people. The same applies to other media information such as in the case of a movie being played and kinesthetic data being provided via an appropriate channel or being determined from audio and / or visual information. It is also possible that movement information is provided via a channel, ie that no analysis has to take place, but already existing data can be evaluated, ie taken over, can be.

For example, as the strength of the selected effect, ie the intensity, in the case of played music, a selection between slight rocking "sway" via "headbanger" towards extreme longitudinal movement, for example referred to as "rodeo", take place. In addition, the LFE channel known from surround sound systems (low frequency effect or low frequency enhancement) also as media information 30 provided or appropriate information can be determined and transmitted in body movement, for example, to enhance sound effects when watching movies. For example, in a representation of an earthquake, the sound effect could be enhanced by transmitting the tremors to the bodywork caused by an earthquake. Visual information, such as horizontal pans could, for example, be enhanced by a supportive yaw motion of the body. In general, a change in the camera perspective, such as zoom, pan, change the depth of focus or focus, etc., and / or associated with motion change of the object shown, for example, the actor just pictured, the pictured mode of transport, etc., instead, then Accordingly, with the kinematic degrees of freedom of the body, a movement can be carried out which supports or optionally also contrasts the perception of the user or the viewer from the outside.

Furthermore, the phase of interventions in the longitudinal movement of the vehicle can additionally or separately be determined. Here again, different scenarios of a common-sense experience or generating the longitudinal acceleration and in the case of played music of the beat ("straight") or a temporally slightly offset (sooner or later) experience or generating the longitudinal acceleration and the beat up to the counteractive experience or generating longitudinal acceleration and beat, are selected via different intermediate stages. The same effect is, as mentioned above, transferable to other media information. This means that even in the case of existing or determined kinesthetic data and / or audio and / or visual information, the phase of interventions in the longitudinal movement can be adjusted.

In a further embodiment, rolling and / or pitching and / or yawing movements and / or vertical movements of the body are generated when corresponding systems in the vehicle 100 are present and have been selected to create the effect. Depending on the setting, which movements are to be performed to the beat of the music, to amplify the audio or kinaesthetic effect, etc., thereby the desired effect for the user 40 , especially the driver and the occupants, or people outside are still significantly strengthened.

These fluctuations can be generated while stationary or while driving. For safety reasons, the limitation of the method is, for example, low speed or standing of the vehicle 100 , low lateral dynamics, low traffic density, etc. possible. Also, an additional limitation on the intensity and / or phase of movement of the body is dependent on the condition of the vehicle 100 or the detection of environmental conditions such as traffic density and existing and required space for performing the method possible.

Specifically, a longitudinal acceleration, for example, only be done if enough space in front of the vehicle 100 is available. In contrast, a yawing moment can only be generated if cornering is possible, safely executable and permitted at this moment. Corresponding information is preferred by those in the vehicle 100 existing assistance systems and provided by the control unit 10 . 11 taken into account in the execution of the procedure.

Also, a limitation of the activation possibility or a limitation of the adjustability of the phase and / or intensity depending on the vehicle occupancy, comprising at least the state may be unoccupied and / or from a detected state of the vehicle occupants. A state of the vehicle occupants may be, for example, that an occupant is sick and therefore should not take place any movements of the body, or that the occupant is in a good mood and therefore stronger movements are desired or could be. The restrictions basically serve the safety of all road users, but should not unnecessarily restrict their comfort.

There are various ways to restrict the movements of the body. In principle, a restriction of the kinematic degrees of freedom can be made to the extent that can be used safely or to a degree that can be used safely for the respective degree of freedom. For example, if the visual file requires forward acceleration with a detected value over a period of time, the traffic situation will not allow it, e.g. due to the too short distance to the vehicle ahead, then the forward acceleration can alternatively be done with a fraction of the determined value and / or end sooner. A special case of the restriction described above would be the use in the state. In this no linear accelerations are possible. In part, these can be replaced by the setting of certain inclinations; thus, the impression of forward acceleration by a rearward vehicle tilt, i. the body is raised at the front and lowered at the back, to be replaced. This is used in a similar form in driving simulators. Another way to ensure traffic safety is to use large open areas in which the individual vehicles play when playing e.g. Move video data fully automatically and autonomously. By vehicle-to-vehicle communication and other sensors for detecting the vehicle environment can be ensured that the vehicles move without dangerous approaches to each other. These open spaces could be used commercially for this application and could become the home cinema of the future.

In addition to manually selecting which movements the body should perform, a selection can also be made by the system if a particular user 40 , in particular a driver and / or occupant has been detected, for whom data relating to preferred use of the effect have already been stored or known or, for example, detected by a mobile device when boarding. Also, an automatic selection can be made depending on detected external influences when the vehicle 100 is traveling without occupants. External influences are outside the vehicle 100 existing persons and / or played and from the vehicle 100 recorded media information 30 like music.

The method can be used both in internal combustion engines and in electric motors, provided that the corresponding systems and actuators are available.

The control of the body movement may be shared with a facility 11 for the evaluation of the media information 30 , So for example, the music and / or audio and / or visual information and / or kinesthetic data on a single controller 10 . 11 carried out, which is also also set up, the corresponding actuators, eg drive 101 and brake 102 to control or regulate. The device 11 for the evaluation of the media information 30 In addition, it can be set up to analyze or evaluate kinesthetic data transmitted via a corresponding channel, ie to record and to output corresponding signals to the corresponding vehicle system for controlling the body movement or to transfer there already existing movement data. Additionally, in the controller 10 . 11 Other functions are realized, for example, the detection and evaluation of driver or occupant data and / or for detecting the external influences for the automatic implementation of the method, ie for the automatic selection of the effect, which movements the vehicle 100 based on the evaluation of the media information 30 should perform. In particular, in the vehicle 100 existing assistance and / or stabilization systems for causing the above-mentioned movements of the vehicle 100 be used so that both an amplification of the music enjoyment and / or the movie enjoyment done, as well as a show effect can be generated. This show effect is visible to both the driver and the occupants as well as to outsiders, so that there is the opportunity to experience otherwise not externally actively perceptible special equipment in action or to demonstrate this in sales situations. By using existing hardware and coupling via bus systems or software, little or no additional costs are required to implement the method.
