Definitions
- the invention relates to a method for operating a motor vehicle, in particular a motor vehicle having a head-up display and an adaptive damper system.
- the invention also relates to a motor vehicle set up to carry out the method.
- head-up displays As an extension of classic display systems, so-called head-up displays, HUD, are used in motor vehicles.
- the term head-up display is derived from
- HUDs are based on the projection of display content onto a transparent screen lying in front of the user, such as the windshield of a vehicle. This creates the impression that the contents of the display are floating freely over the hood in the driver's field of vision at a distance of around two and a half meters.
- the driver therefore does not have to adjust his head position or his line of sight, for example lowering (“head-down”), in order to perceive the display contents.
- conventional display means such as in
- the user cannot briefly perceive the events occurring in front of the vehicle when looking at the display means.
- kHUDs which with the help of augmented reality, AR, technology enable the transparent overlay of the driver's distant field of vision and, in particular, the display of virtual information overlaying a relevant object in the street scene. For example, an indicator for warning people can be displayed superimposed on the person in the far field of vision of the driver.
- kHUDs spatial and temporal discrepancies between the superimposed representation of the virtual display over the real object have a particularly negative effect on the impression of the superimposition and, accordingly, on the functionality of the system. Starting from a representation of a real object with virtual content that is initially superimposed at the correct location and time, movements of the vehicle body in particular lead to such spatial and temporal discrepancies.
- the movements of the vehicle body are usually induced by the roadway being driven on or by the vehicle's acceleration and steering processes.
- a compensation of the body movements by adapted representation of the virtual content is conceivable, but requires precise knowledge of the movements of the vehicle body.
- the known sensors and methods for predicting vehicle body movements are disadvantageous in not being able to provide information on these movements with high accuracy and at the same time low latency.
- One aspect of the present invention relates to a method for operating a motor vehicle, the motor vehicle having at least one contactless head-up display, kHUD, and a semi-active damper system.
- the kHUD is set up to display at least one virtual content overlaid with at least one real object.
- the real object is, for example, a person in front of the vehicle, and the virtual content is, for example, a person warning indicator.
- the real object is a traffic sign and the virtual content is a traffic sign indicator.
- the real object can be a bend in the street and the virtual content can be a navigation instruction. Further configuration options for an augmented display are known to those skilled in the art.
- the semi-active damper system of the vehicle is a damper system which is set up to be operated selectively with one of a plurality of damper characteristics.
- Damper systems can essentially be divided into three groups, namely passive, active and semi-active damper systems. Passive damper systems can only be adapted once by selecting the components of the damper system, in particular springs and dampers, to an anticipated roadway or route profile. In active damper systems, components such as springs and dampers are replaced by actuators, which generate the forces otherwise exerted by these passive components.
- Semi-active damper systems Semi-active
- Damper characteristics can be changed over a wide range by means of suitable control.
- the motor vehicle of the method according to the invention has a semi-active damper system.
- the semi-active damper system is preferably set up so that a flow of the im
- Damper used fluids is adjusted. This takes place particularly preferably in that the flow resistance experienced by the fluid is adapted by means of (proportional) adjustment valves.
- the rheological properties of the fluid used are also preferably adapted. In the case of magneto- or electrorheological fluids, this is preferably done by applying a suitable electromagnetic field.
- the semi-active damper system is particularly preferably set up to adapt the flow resistance experienced and to adapt the rheological properties of the fluid (fluid viscosity).
- the damper characteristic of the semi-active damper system defines the response (reaction such as
- the characteristic damper curve can be stored as such and / or describe the real behavior of the damper, which can be continuously adjusted, for example, via a valve value.
- the motor vehicle used in the method according to the invention also has further components, as will be explained in greater detail below.
- the motor vehicle used in the method according to the invention has a control unit which is set up to carry out the method according to the invention.
- the method according to the invention has at least the following method steps.
- Detection of the real object usually precedes the detection of the real object. This detection is preferably carried out by means of at least one first sensor designed to detect environmental information.
- the first sensor is preferably a camera, an ultrasound-based detector or a detector based on laser light (LIDAR).
- the detection of the real object is usually followed by an automated recognition of the object using signal processing methods, for example algorithmic ones
- the method according to the invention provides information about a real object located in the direction of travel of the motor vehicle, this information being a specification of the object (for example category: traffic sign, type:
- the position information includes in particular a distance and a relative orientation to the vehicle.
- the position information is preferably recorded directly from the vehicle (for example by means of LI DAR) and / or derived from the computerized image information recorded (for example based on known dimensions of objects).
- a virtual content for augmenting the recognized real object is also determined.
- different indicators are preferably used for augmenting different classes of real objects. These indicators differ, for example, in color, shape, size and the like.
- the navigation instruction may also depend on a planned route guidance of the motor vehicle.
- the selection of the virtual content is also preferably dependent on user preferences and / or user settings.
- the virtual content is also displayed superimposed on the real object by means of the kHUD.
- the virtual content is projected onto a projection surface in such a way that the projection is perceived by a driver of the motor vehicle superimposed on the real object.
- the positioning of the virtual content depends not only on the relative position of the real object to the motor vehicle but also on the relative position of the driver, in particular his eyes, to the projection surface.
- the relative position of the real object to the motor vehicle is derived from the position information and the relative position of the driver to the
- Motor vehicle is preferably stored in a control unit of the motor vehicle and is particularly preferably based on an initial configuration and / or a user profile of the driver.
- the projection surface is preferably the entire surface of a transparent screen or the windshield of the motor vehicle, in which, in principle, the virtual content can be displayed by means of a HUD.
- the virtual content is also preferably projected by means of the HUD over the projection surface into a field of view of the driver.
- the main purpose of the projection surface is to reflect the projected virtual content into the driver's field of vision. Due to the transparency of the screen or the
- Windshield this reflection takes place like on a semi-transparent mirror. So takes the driver compares the virtual content projected by the HUD with that behind the
- Windshield located environment (or lane) superimposed true.
- one of the plurality of is also selected
- Damping characteristics of the semi-active damper system in preparation for the presentation of the virtual content in particular in preparation for the presentation of the virtual content in
- the augmented display of the virtual content does not take place permanently but only temporarily, for example for the situational augmentation of real objects temporarily located in the direction of travel of the vehicle.
- the augmented display of the virtual content takes place only at a specific point in time or only for a specific period of time.
- a selection of one of the plurality of damper characteristics of the semi-active damper system in preparation for the display of the virtual content thus designates a selection of such a damper characteristic in advance and with regard to the
- the selection is not only made beforehand but also correlated in time with, i.e. in preparation, the display.
- the selection takes place within a predetermined period of time before the display and / or within a predetermined period of time after the determination of a virtual content for augmenting the recognized real object.
- the method step of determining a virtual content for augmenting the recognized real object in the method according to the invention thus solves this
- the characteristic damper curve is selected in such a way that an expected vehicle body movement is minimized. It is known from the prior art that different settings of a semi-active damper system can be performed with the same force acting on the vehicle
- a specific setting or a specific damper characteristic of a semi-active damper system can be specific mean vehicle response to a defined force can be assigned. This also allows the identification of at least one characteristic damper curve which, with constant action on the motor vehicle, results in a movement of the
- such a damper characteristic is preferably selected in preparation for the augmented display of the virtual content.
- this also has the method step of operating the semi-active damper system with the one selected damper characteristic at the moment the virtual content is displayed. Since the selected damper characteristic has preferably been selected in such a way that an expected vehicle body movement is minimized, the movement of the vehicle body is actually minimized at the moment the virtual content is displayed. Thus, in the method according to the invention, the development of discrepancies between the position of the displayed virtual content and the real object is advantageously counteracted by reducing the probability and / or amplitude of vehicle body movements.
- the augmented display generally only takes place for a short time, so that the operation of the semi-active damper system with the one selected damper characteristic is preferably only for a short time, for example within a predetermined interval around the augmented one
- the semi-active damper system is set up for operation with continuously variable damper properties.
- different operating modes of a semi-active damper system i. different
- Damper characteristics have an enormous influence on vehicle body movements.
- a large number of known semi-active damper systems do not work with such
- Damper behavior any current can be applied to continuously open or close a valve built into the damper strut.
- the degree of opening of the valve and thus the damper characteristic changes continuously or in any number of stages.
- one of the plurality of damper characteristics is nevertheless selected.
- the one selected damper characteristic is preferably a predefined damper characteristic of the semi-active damper system and preferably corresponds to a defined one Operating modes.
- the selection of a certain characteristic damper curve advantageously enables a clear characterization of the semi-active damper system even with a continuously adjustable damper system. This is advantageous both for the operation of the damper system and for the simulation of the motor vehicle during the augmentation. In this way, it is preferably ensured during operation that movement of the vehicle body is minimized.
- Simulation of the motor vehicle with a clearly characterized damper characteristic advantageously enables the determination of precise display corrections for the augmented display.
- an expected vehicle body movement of the motor vehicle is also determined based on the selected one damper characteristic. Regardless of the original cause of the vehicle body movement, the damper characteristic always goes into
- the representation of the virtual content is also adapted in overlay with the real object to compensate for the expected vehicle body movement of the motor vehicle.
- the adaptation of the display of the virtual content takes place by shifting a projection position of the virtual content in a direction opposite to the expected vehicle body movement. If, for example, it is determined that an upward pitching movement of the front of the vehicle body is to be expected, the projection position is shifted downward. Likewise, in response to an expected clockwise rolling movement, the projection position is rolling in a counter-clockwise direction. In response to any yawing of the vehicle body to the left, it is possible to react by shifting the projection position to the right. All shifts in the projection position relate to the projection surface (windshield) from the driver's point of view.
