Description

The invention relates to a method for assisting a vehicle user of a vehicle in maneuvering and parking the vehicle, the surroundings of the vehicle being displayed therein.

From the DE 10 2010 030 463 A1 a method for assisting a driver of a motor vehicle in a driving maneuver is known. In a first step of the method, the surroundings of the motor vehicle are recorded and a two-dimensional representation of the surroundings of the motor vehicle is displayed. In a second step, a desired end position of the motor vehicle is entered by the driver, the end position being marked in the two-dimensional representation. In a final step, a trajectory for reaching the end position is determined and instructions are issued to the driver to follow the trajectory, or an automatic driving maneuver is carried out in which the motor vehicle is maneuvered into the end position.

The invention is based on the object of specifying a method for supporting a vehicle user of a vehicle.

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

Advantageous embodiments of the invention are the subject of the subclaims.

A method for assisting a vehicle user of a vehicle in maneuvering and parking the vehicle, with the surroundings of the vehicle being displayed therein, provides, according to the invention, that possible parking spaces in the surroundings of the vehicle and trajectories with a number of necessary maneuvering moves to reach a respective parking space are displayed, with a number of parking spaces being highlighted with a respective associated trajectory that is rated as suitable for a vehicle user. In addition, the method provides that as soon as an assistance function detects an impending turning maneuver of the vehicle, possible and optimal turning trains are displayed. In addition, warnings about static and dynamic objects in the vehicle's path are output, maneuvering points and parking end positions of the vehicle are displayed using a semitransparent vehicle contour and the vehicle user is given steering instructions when a need is recognized.

By using the method, the vehicle user can be supported in maneuvering and parking the vehicle, the trajectories being planned by a corresponding assistance system, the planned trajectories being presented without explicit input from the vehicle user.

Since this assistance system does not itself control the vehicle transversely and longitudinally, the vehicle user can influence and also correct the driving maneuvers proposed by the assistance system comparatively quickly and according to human perception of the surroundings.

The vehicle user can immediately see after an augmentation whether there is a single option to maneuver or park the vehicle, or whether it is necessary to change gear.

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

Show:

• 1 schematically a display of different trajectories for parking end positions of a vehicle,

• 3 schematically a display of different trajectories for maneuvering the vehicle with a trailer.

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

1 shows an ad A. different trajectories T1 to T8 for different possible parking space end positions P1 to P5 of a vehicle 1 . For example, the ad is A. Part of a head-up display unit and / or another suitable display unit located in the field of vision of a vehicle user.

Automated maneuvering and parking are comparatively slow in terms of their characteristics and series execution and, depending on a scene, ie an environment, are of no benefit to the vehicle user. For this reason, the vehicle user often resorts to manual operation of the vehicle 1 back though the vehicle 1 a parking assistant, a bottleneck assistant, a reversing assistant and / or a trailer assistant.

In particular, longitudinal and lateral guidance of the vehicle 1 during manual maneuvering, e.g. B. in trailer operation, so how individual maneuvering trains are ideally carried out, can overwhelm the vehicle user depending on the scenery and driving ability of the vehicle user.

In particular for a vehicle user who, at least at his own discretion, is better, i.e. faster and more precise, in an end result than longitudinal and / or transverse control assistance functions of the vehicle 1 and this is not activated because of the automated, uncooperative behavior, in particular since the corresponding assistance function is aborted in the event of a vehicle user intervention, a method described below is suitable.

In addition, the method described below is aimed at a vehicle user for whom an operating chain of a respective assistance function is not intuitive, familiar or entirely comprehensible in which situations the parking assistant, the bottleneck assistant, the reversing assistant and / or the trailer assistant can provide assistance to the vehicle user .

In particular, by means of the method, the vehicle user of a vehicle 1 when maneuvering and parking the vehicle 1 supported, being an environment of the vehicle 1 is displayed in this.

By means of the method, an extension of the assistance functions is made available to support the vehicle user, which trajectory planning options for maneuvering and reaching a parking space end position P1 to P5 determined. A number of trajectories that are not necessarily entered by the vehicle user are thereby used T1 to T8 considered.

Depending on a scene, ie the surroundings of the vehicle 1 , become parking lot end positions P1 to P5 and / or maneuvering positions, e.g. B. driveways, bays, intersections, curves, etc., for a vehicle 1 with an in 3 shown trailer 2 , recognized.

All determined and planned trajectories T1 to T8 will be on the display A. displayed, with the trajectories T1 to T8 are continuously updated depending on the vehicle movements carried out. So it can be that there are further ideal trajectories T1 to T8 due to the vehicle movement, whereas other trajectories T1 to T8 may be omitted.

There is a so called park view on the display A. activated by the activated assistance function, for example by actuating a corresponding control element, by means of voice input by the vehicle user, based on a global localization of the vehicle 1 , due to a current driving speed and / or due to the driving behavior of the vehicle 1 , are available parking spaces P recorded and displayed on the vehicle side.

In addition to the parking spaces P the trajectories are dependent on a current vehicle position T1 to T8 with a number of maneuvering trains required to reach a respective parking space end position P1 to P5 on the display A. shown.

In 1 are different trajectories T1 to T8 shown, in this case, for example, between cross-forward parking, cross-rear parking and longitudinal rear-parking by means of different types of lines used to represent the different trajectories T1 to T8 is distinguished.

The procedure to support the vehicle user of the vehicle 1 uses a so-called cloud connection, a connection to a vehicle-mounted navigation system and artificial intelligence, in particular a classifier and scene interpretation, so that based on the surroundings of the vehicle 1 it is recognized whether the vehicle 1 z. B. at a home address, a shopping address and / or a work address, so that a self-activation of the ad A. can be optimized to support the vehicle user.

Furthermore, it is provided that the trajectory planning options are adapted to a maneuvering behavior usually carried out by the vehicle user.

With regard to the determined trajectories T1 to T8 to a respective parking space P become the trajectories T1 , T2 highlighted, which can be followed most easily and / or which correspond to an individual behavior of the vehicle user, ie which are intuitively suitable based on the individual behavior of the vehicle user.

Other trajectories, not shown, that the vehicle user uses to park the vehicle 1 would not choose can remain hidden from the start.

Maneuvering points M. as in 3 end positions shown P1 , P2, P3 of the vehicle 1 are by means of a semi-transparent vehicle contour F. shown.

As soon as an in 2 shown intended turning maneuver of the vehicle 1 is recognized, for example because the vehicle 1 unforeseen, e.g. B. on a roadway with no parking spaces P the vehicle user activates a direction indicator, the wrong route is indicated on the basis of navigation data and / or the vehicle user calls up the function to support the turning maneuver, possible and optimal trajectories become possible T1 to T3 with the corresponding number of maneuvering moves on the display A. shown.

Here, too, it is provided that the trajectory that is easiest to travel on T1 highlighted on the display A. is shown.

By using the method, the vehicle user already knows before the turning maneuver whether there is a train to turn the vehicle 1 is sufficient.

Regardless of whether the vehicle 1 If you intend to park or maneuver, static and dynamic objects become warning signs in the vehicle 1 output, whereby the vehicle user is made aware of the respective object.

For example, a warning z. B. at bottlenecks, such as a toll station, a gas station, a garage, a parking garage, as static objects and in oncoming traffic, pedestrians and / or cyclists as dynamic objects.

Becomes a parking end position P1 to P5 of the vehicle 1 on the display A. shown, the vehicle contour F. with the vehicle doors open, in addition to the output of the warning notice with regard to objects in the vicinity of the vehicle 1 an augmented impression of a free space around the vehicle 1 offering around. It can thus be shown how far the respective vehicle door is in the corresponding parking space end position P1 to P5 can be opened.

Is the vehicle 1 , as in 3 is shown with a trailer 2 coupled, the vehicle user is given steering instructions when towing the trailer, which the vehicle user can use when maneuvering the trailer 2 support.

In the course of the method, the vehicle user can make a selection as to which trajectory T1 to T8 it is preferred, with the vehicle alternatively recognizing which trajectory T1 to T8 the vehicle 1 follows. Is one of the trajectories T1 to T8 selected or recognized by the vehicle, then the other trajectories T2 to T8 shown paler.

Furthermore, a smooth transition from one or into one of the function longitudinal and / or transverse maneuvers, z. B. for parking, for example, by the vehicle user taking his hands off the steering wheel, by issuing a voice command and / or by actuating a corresponding control element.

To make the display clearer A. as a user interface to increase the assistance functions mentioned above, can be used for the multi-section trajectories T1 to T8 and in particular the trajectories T2 bis not followed by the vehicle user T8 also only a first train and / or a first comparatively short section of the trajectories T2 bis not used T8 being represented.

The method therefore not only produces a trajectory T1 to T8 planned, offered and augmented when the respective assistance function is activated, with the trajectories T1 to T8 can be updated as a function of vehicle movement. The ad A. shows the possible trajectories T1 to T8 both when handing over a driving task to the respective assistance function and when the vehicle user takes over the driving task.

A selection of the trajectories T1 to T8 makes use of all available information, for example an environmental sensor system, a navigation system, a cloud, in particular a maneuvering behavior of the vehicle user determined and / or learned using artificial intelligence, a scene interpretation and / or a localization of the vehicle 1 .

There are also several trajectories T1 to T3 shown for selection if the vehicle 1 with a trailer 2 is coupled.

The vehicle user has the option of activating and deactivating the function shown using the method described.
