Preferred embodiments of the present invention are shown in the drawings and are further set forth in the description below with reference to the drawings. Thereby illustrating further advantages of the present invention. Like reference numbers, even among different figures, refer to identical, similar, or functionally identical components. Corresponding or similar features and advantages are achieved even when not repeatedly stated or referred to herein. The drawings are not, or at least not always, to scale. In the drawings, the scale or spacing is exaggerated in order to clearly highlight features of the embodiments.

Schematically, there are:

figures 1a to 1g show the flow of the pull-out procedure of the method according to the invention,

figure 2 shows a separate view of a motor vehicle adapted to perform the method together with the resulting light appearance image,

figure 3 shows a view of the motor vehicle about to undergo a lateral parking out process,

fig. 4 shows a separate view of the motor vehicle according to fig. 3 together with the resulting light appearance image.

Reference is first made to fig. 1. In these figures, a motor vehicle K1 can be seen, which is located in parking space P. The parking space P is one of a plurality of parking spaces P, which is arranged side by side with the street road F1. F2 represents an oncoming road of a street.

Parking space P is arranged with its longitudinal extension obliquely with respect to road F1. In contrast to this exemplary embodiment, the method can also be carried out if the parking space P is oriented with its longitudinal extent perpendicularly with respect to the road F1.

Such traffic situations often arise. For motor vehicle K2 approaching at speed V2, it is often difficult to recognize the willingness to park of such parked vehicle in good time due to the parked vehicle in front of vehicle K1. This is also the case if the motor vehicle switches on the steering indicator, engages the reverse gear and switches on the reverse light in this way before the planned parking process.

This disadvantage is compensated in the present exemplary embodiment by the fact that the light appearance image 1 is produced on the road surface F1 during the parking maneuver by the vehicle's own lighting device (not shown here) of the vehicle K1.

The light appearance image 1 is clearly visible by the motor vehicle K2 or by the driver thereof. The detailed design is described in more detail below.

It is to be mentioned that the light appearance image 1 was already produced by the motor vehicle K1 when the reverse gear was engaged. Thus, approaching traffic participants are indicated in advance that the motor vehicle K1 intends to park out (see fig. 1 a).

Due to the design of the light appearance image 1, the intended parking of the motor vehicle K1 is known in advance by the motor vehicle K2, so that the motor vehicle K2 stops at a sufficient maneuvering distance on the imaginary stop line H2 (see fig. 1 b).

The driver of vehicle K1 now notices himself that his desire to park has already been recorded by vehicle K2. Subsequently, the motor vehicle K1 exits from the parking space P at a very low speed v1 (see fig. 1c and 1 d).

Finally, the parking process of vehicle K1 is ended, and vehicle K1 stops at imaginary stop line H1 at a small distance from vehicle K2 (fig. 1 e).

Note that the orientation of the light appearance image 1 and the spacing from the vehicle K1 remain unchanged throughout the parking process. Therefore, the light appearance image 1 moves together with the bullet train K1 (see fig. 1a to 1 e).

After the parking process, the driver of the motor vehicle K1 again engages the forward gear and first travels in the normal driving direction at a lower speed v 1. The light appearance image 1 is extinguished, preferably when the forward gear is engaged. Due to the goodness and forgiveness of the waiting motor vehicle K2, which the driver of the motor vehicle K1 wishes to thank, a further light appearance image 1' is then generated briefly on the road F1. The light appearance image 1' is used to transmit thank you information to the vehicle K2. In this embodiment, it is a friendly face blinking towards the vehicle K2 (see fig. 1 f).

In contrast to the present exemplary embodiment, other light-oriented images are naturally also conceivable, with which a corresponding thank you can be transmitted to the motor vehicle K2. For example, by a graphic showing the thumb pointing upwards or a "thank you! "is realized by the character information.

The generation of the motor vehicle K1 and the light appearance image 1 will now be explained in more detail with reference to fig. 2. For this purpose, motor vehicle K1 has a lighting device 2 and a lighting device 2' arranged in the rear roof region of the vehicle. Furthermore, on the left, in the middle roof region, there are a light 2 and a light 2'. The lighting device 2 is a light projection device with which a fully illuminated light section S can be projected onto the road F1.

It is alternatively conceivable that one or more linear contours K, which delimit the defined surface, can be formed on the road F1 by means of the light-emitting device 2' embodied as a laser unit.

Which light emitting device (2 or 2') is used depends on the light conditions of the environment. Which is measured by a sensor 6 designed as a brightness sensor. The sensor 6 is connected to the evaluation and control device 7 by means of a data bus C, which is preferably designed as a CAN bus.

If the ambient brightness exceeds a certain stored limit value, for example in daylight, the light appearance image 1 is generated by means of the lighting device 2', i.e. by means of laser light, and the aforementioned contour K with a correspondingly high optical density is formed on the road surface F1. If the threshold value is undershot, for example at night or at dusk, it is sufficient to use the lighting device 2 and to generate the light section S.

As mentioned above, the light appearance image 1 may have only one or even a plurality of such light segments S or contours K. In any case, the light appearance image 1 is generated such that an imaginary envelope surface F is generated at a distance a behind the motor vehicle K1.

Here, the envelope surface F is formed in this embodiment by a rectangular bounding box of lines or corners of the exterior of the light-look image 1. The envelope surface F is thus the product of the width b and the length l of the bounding box.

In contrast, the motor vehicle K1 has an envelope surface F_KThe envelope surface is formed by the width b of a flat-shaped frame surrounding the motor vehicle K1_KAnd length lk.

In order to fulfill the function of the method according to the invention and to bring the light appearance image 1 to the attention of other traffic participants, the envelope surface F of the light appearance image 1 generated behind the motor vehicle K1 is at least the envelope surface F_KAbout one third of such a size scale.

To further increase the effect of the light appearance image 1, the light appearance image 1 is produced with a spacing a behind the motor vehicle K1, which is in the range of about one-seventh up to about one-fourth of the length lk, i.e. of the motor vehicle K1.

The motor vehicle K1 also has a sensor 3 arranged at the rear of the motor vehicle, which is preferably designed as an ultrasonic sensor of the parking aid. By means of the sensor 3, the motor vehicle 1 can detect whether an obstacle is present behind the motor vehicle K1 at the time of engaging the reverse gear. It can be detected by the shift monitoring device 9 whether reverse or forward gear is engaged.

However, alternatively and/or additionally to the sensor 3, it is also conceivable to use at least one sensor 8, which may be designed, for example, as a camera. Such a sensor can be arranged, for example, on the roof of a motor vehicle K1.

If a static obstacle behind vehicle K1 is detected when the reverse gear is engaged, which therefore does not change during the cycle measurement (but does change when a vehicle passes by), vehicle K1 is not assumed to be located in a parking space that is inclined or vertical with respect to the lane. It is conversely possible for the vehicle K1 to be parked, for example, in a parking space oriented parallel to the road and between two other vehicles. In order to save energy, the light appearance image 1 is therefore not produced when the reverse gear is engaged in this case.

It is furthermore noted that the width b of the envelope surface F is preferably equal to or smaller than the envelope surface F_KWidth b of_KI.e. the width of the motor vehicle K1. It can furthermore be seen that the light appearance image 1 contains a direction indication R. The direction indicator R points backwards, i.e. opposite to the general direction of travel. In the present exemplary embodiment, the direction indication R is implemented in such a way that the light section S or the contour K is designed to point backwards in the form of an arrow. Furthermore, the thickness d of the light section S or contour K decreases as the distance from the motor vehicle K1 increases. Thereby also increasing the intelligibility of the visual information.

As already mentioned, the generation of the light appearance image 1' (see fig. 1f) serves to transmit thank you information briefly to the other traffic participants, in this case to the driver of the motor vehicle K2. The generation of the light appearance image 1' can be generated manually by the driver of the motor vehicle K1 by means of the switch 5. However, it is also conceivable to automate this via the input and display device 4, which input and display device 4 can be designed, for example, as a screen of a vehicle computer. It can be provided, for example, by the input and display device 4 that after the light appearance image 1 is generated, the light appearance image 1' is generated substantially in a short time when the forward gear is again engaged.

Fig. 3 shows how the motor vehicle K1, similarly to the method described above, moves in the face of a lateral parking action from a parking space P arranged parallel to the road F1. In this case, the light appearance image 1 is generated laterally on the road F1 at the motor vehicle K1, preferably after the driver has actuated the left steering indicator FA and/or the steering deflection angle to the left has reached a certain limit value. These triggers are monitored by a steering angle sensor 10 and by a steering indicator monitoring device 11 (see fig. 2 or 4). In other respects similar to the backward park out process. After the lateral parking process, a further light appearance image 1' (see fig. 1f, not shown here) is generated again, preferably with the steering wheel being set (steering angle equal to zero).

Figure 4 again shows the important dimensional relationships. Even in the case of a lateral pull-out, the envelope surface F of the light representation 1 at least approximately corresponds to the planar envelope surface F of the motor vehicle K1_KOne third of the total is consistent. The lateral distance a of the light appearance image 1 from the motor vehicle K1 is at the width b of the motor vehicle K1_KIn the range of about one-fifth up to about one-half. With this distance a, it is achieved that the light appearance image 1 is generated on the road F1 not too far in the direction of the oncoming road F2.
