Description

The invention relates to a motor vehicle comprising a projection system having at least one first and at least one second projection device, wherein the at least first projection device has at least one first light source and the at least second projection device has at least one second light source.Modern motor vehicles frequently have parking assistance systems. These parking assist systems usually comprise functions and devices which allow the user to operate the motor vehicle more easily and to handle it more easily when parking. These include, for example, backup cameras, lateral parking aids, automatic parking and backup assistants or else remote parking by means of an external operator control unit.DE 10 2018 220 325 A1 discloses a projection apparatus with the aid of which a parking maneuver can be carried out. A user controlling the vehicle receives a visible representation of the vehicle trajectory, with the aid of which the user can identify potential collisions. For use of the projection device, an indicator, which is arrows or a path line, can be projected onto the ground in order to realize a visible representation of the destination route.DE 10 2017 210 221 A1 describes a method for the longitudinal and transverse guidance of a motor vehicle. In this case, environment data relating to the motor vehicle are ascertained and a plurality of possible trajectories are output as a function of these. The user can select a trajectory via an operating unit, as a result of which the motor vehicle is guided at least partially automatically along at least one section of the selected trajectory.DE 10 2018 202 526 A1 discloses a method for operating a driver assistance system of a motor vehicle, which method provides a parking aid. For this purpose, a marking is projected onto an adjacent ground area by means of a navigation target specification device, for example in the form of an image. This defines the area in which the motor vehicle is intended to stand after the following automatic navigation of the motor vehicle. The navigation path is determined by a control device depending on the given marking, which is detected via a detection device.DE 10 2006 050 550 A1 describes a method for controlling an at least partially automatic driving maneuver in order to move the vehicle from an actual position into a desired position. For this purpose, a virtual target object is generated in the environment of the motor vehicle by projection by means of projection means provided on the motor vehicle at a target position for the motor vehicle in the environment of the motor vehicle, after which the target position is changed as a function of operating actions of an operator of the motor vehicle, as a result of which the target object is also displaced in the environment of the motor vehicle, The changed target position is selected by a selection action of the operator and is adopted as the target position of the subsequent driving maneuver.The object of the invention is to specify an improved motor vehicle.To solve this problem, a motor vehicle of the type mentioned at the beginning is provided, in which at least one first light projection into the surroundings of the motor vehicle can be projected by the at least first projection device, wherein the at least first light projection defines an actual position of the stationary motor vehicle, and at least one second light projection into the surroundings of the motor vehicle can be projected by the at least second projection device, wherein the at least second light projection defines a setpoint position defining a parking position of the motor vehicle, wherein the at least second projection device can be adjusted by the user in order to change the setpoint position, wherein a deviation between the actual position and the setpoint position can be determined by a detection device, wherein control parameters for carrying out an autonomous driving maneuver can be determined by a control device as a function of the determined deviation, In the context of which the motor vehicle can be autonomously maneuvered into the parking position can be determined.The motor vehicle according to the invention thus has a projection system which outputs both a setpoint position with which a specific end position of the vehicle is to be displayed after a maneuvering operation and an actual position which defines the present position of the stationary motor vehicle. This offers the advantage that an accurate visualization of the actual and the target position of the motor vehicle is made possible via this system, whereby the deviation between the actual and the target position is calculated via a detection device and an autonomous driving maneuver is initiated via a control device. This is because, on the one hand, the control device can use the actual desired data to exactly record the starting and the end position of the intended driving maneuver, and on the other hand, based on these position details or position deviations, it is possible to determine a trajectory along which the vehicle can be maneuvered from the actual position into the desired position in an autonomous driving maneuver. A further advantage of this device is that the user of the motor vehicle is permitted optimum visibility of the two positions. Since the user can set the at least one second projection device automatically, a very high flexibility with respect to the adaptation of the desired position to the desired position is made possible. The user can consequently define the desired parking position via the adjustable desired position, such that the vehicle is positioned as desired after carrying out the automatic driving maneuver. Parking in narrow or poorly visible positions, for example on or between pillars, walls or parked cars, can thus be facilitated for the user. Furthermore, the display of the two positions allows the user to intuitively operate the projection system in order to get into the desired parking position.According to the invention, the at least one first projection device and the at least one second projection device can be designed to generate at least one first and at least one second light projection, which define an actual position and target position located laterally and / or in front of and / or behind the vehicle. In a preferred configuration of the invention, the at least one first and the at least one second projection device are located laterally on the motor vehicle, whereby at least one representation of the actual and the desired position can be made possible laterally with respect to the motor vehicle. The position parallel to the vehicle longitudinal axis can be defined thereby. In addition, the actual and the desired position can also be represented at least partially in front of and / or behind the vehicle, whereby the position in the direction of the vehicle longitudinal axis can be defined. Thus, two positions defining the end position, one laterally, the other forwardly and / or rearwardly, can be displayed simultaneously via a light projection. In addition, the angle of the desired position relative to the vehicle longitudinal axis or to the actual position, which defines the present position of the vehicle and is thus stationary, can also be set by the user in order to achieve the setting of the desired parking position. This may be necessary above all when the vehicle is to be maneuvered into a parking position obliquely to its present position. Furthermore, the at least one first and the at least one second light projection can be output with the smallest possible lateral offset with respect to the vehicle longitudinal side of the motor vehicle. As a result, the most precise possible representation of the position of the motor vehicle or of its outer side can be output. This makes it possible for the user to be better able to assess whether the desired position selected by him is suitable in order to reach the desired parking position without collision.According to a further development of the invention, the at least one first projection device and the at least one second projection device can be designed to generate at least one first and at least one second light projection in the form of lines. The advantage here is that the line representations virtually show the course of the elongate side of the vehicle or of the front or of the rear, with the result that an output of these lines can offer the user the most illustrative form of the representation of the vehicle image in the actual position and also the desired position. In addition, however, further configurations are also conceivable. Thus, it may also be possible to output the light projections in the form of dots, a line-line or geometric shapes. Further user-specific representations such as color, intensity or line strength can also be set.Furthermore, the detection device can be a sensor, in particular an optical sensor, or a camera. In one embodiment with the first alternative, sensors are possible which can detect the light projections, in particular in the form of the lines. Examples include photoelectric sensors which can detect differences in brightness or color, for example. In the second alternative, the camera can preferably be configured for image analysis. Thus, for example, the actual and target position represented in the form of lines can be captured by the camera and evaluated via software provided for this purpose. On the basis of the detected positions and distances between these, the software can calculate and output a sensor detection result in the form of position data, on the basis of which the control device can in turn calculate its control parameters.Furthermore, the at least one first light source and the at least one second light source of the projection system can each have at least one laser diode and / or at least one LED. An embodiment with a laser diode is preferred here. While both laser diodes and the LEDs have a very long life, the laser diode has the advantage over the LED that the laser diode does not lose light intensity even with increasing age. Since lasers operate in a very narrow wavelength range, unlike LEDs, lasers produce a high intensity light and can also present it with a higher precision than LEDs. In this case, any desired geometries can also be produced by means of lasers. Finally, ambient air containing many suspended particles, such as in a poorly ventilated parking garage, can adversely affect the light intensity of LEDs. The light intensity of lasers is not impaired thereby. Optionally, the at least one first and the at least one second light source can have both a laser diode and an LED. This would be advantageous in particular in the presence of a defect in one of the diodes, since then at least the respective other diode is capable of outputting the light projection.Furthermore, according to the invention, at least one first and at least one second projection device and at least one detection device can be provided on both sides of the motor vehicle. In a further preferred configuration of the invention, the at least one first and the at least one second projection device and / or the detection device can be arranged on a side mirror, a roof rail, a sill or a bumper in the front and / or rear region. In the latter alternative, the projection devices are preferably attached to the outer third of the bumper in order to enable the greatest possible lateral deflections of the light projections. While it is possible for the projection devices to be arranged on only one side of the motor vehicle, a configuration in which a further pair of projection devices consisting of a first and a second projection device is additionally arranged on the other side of the motor vehicle is favored. In this embodiment, a pair of projection devices would thus be present on each side of the motor vehicle. In such an arrangement, depending on whether the potential parking position is located to the left or right of the motor vehicle, the user can select the at least one first and the at least one second projection device on one of the two sides in order to output the at least one first and the at least one second light projection and to set the desired position accordingly.In addition, a surroundings detection device may be provided which is designed to detect obstacles in the surroundings of the motor vehicle and to output surroundings detection information, the control device being set up in such a way that the control parameters are ascertained on the basis of the surroundings detection information. These may preferably be distance or proximity sensors such as, for example, ultrasonic, radar or lidar sensors. Depending on the surroundings detection information, the control device can then determine control parameters so that a possible obstacle can be bypassed. After the determination of these control parameters, the autonomous driving maneuver can be carried out. The detection of an obstacle via the environment detection device has a protective function. The environment detection device can carry out a current obstacle detection, the results of which are transmitted to the control device. As a result, both fixed obstacles such as, for example, walls, pillars, vehicles, etc. and also movable obstacles can be detected. If an unpredictable situation occurs, in which, for example, a person is running in front of the vehicle as a movable obstacle, this can be detected by the environment detection device, transmitted to the control device and the driving maneuver can then be terminated and, if the obstacle is no longer in the travel path, resumed. Subsequently, a new setting of the desired position can be requested by the user. However, it is also conceivable that in such a situation, in which a driving maneuver has to be aborted due to an unpredictable obstacle, the projection devices defining the setpoint position automatically define a preferred setpoint position and output the corresponding light projections. On the basis of the newly set setpoint position and the environment detection information, the control device can calculate new control parameters on the basis of which a new driving maneuver can be carried out. If a driving maneuver is interrupted or if it is impossible to carry out this driving maneuver at all, an acoustic warning signal can be output via loudspeakers or an optical warning signal can be output via the headlights or the projection devices of the motor vehicle. In addition, a notification can also be sent to the user to his desired external operating unit.According to the invention, an environment detection device can be provided which is designed to determine the environment of the motor vehicle and to output an environment detection information item, wherein the at least one first and the at least one second projection device are configured to control the at least one first and the at least one second light projection on the basis of the environment detection information item. It is possible here for the environment detection device to ascertain an environment detection information item, for example relating to the brightness of the environment or the dryness or the nature of the underlying surface serving as a roadway. Depending on the information determined, parameters can be changed via the projection devices, which parameters serve for better visualization of the light projections. For example, in the case of strong sunny and thus high brightness, the color intensity of the light projections can be reduced and / or a darker color can be selected, so that the light projections are more clearly evident. Furthermore, on uneven ground, for example in a ballast road, the strength of the lines shown can be increased in order to make them more clearly visible. In addition to the line strength and the intensity, an adjustment of the color and brightness of the individual light projections is also conceivable. These settings can also be individually adjusted by the individual user.In a further configuration of the invention, the at least one second projection device for setting the desired position can be controlled by the user via an external and / or internal operating unit. The external operating unit can be a tablet, a laptop or a mobile telephone, and the internal operating unit can be a touch display installed in the vehicle. If the user sets the desired position via an external operating unit, the user is preferably located outside the motor vehicle. For this purpose, a corresponding application can be loaded onto the external operating unit of the user, via which the setting of the desired position can be realized. In addition to the setting of the line of the desired position, which is located parallel to the vehicle longitudinal axis, the lines of the desired position, which are located in front of and / or behind the vehicle and which define the positions in the direction of the vehicle longitudinal axis, can additionally also be set by the user via the external operating unit separately from the latter. Within the application, at least in a simplified representation, the motor vehicle, its environment and the actual and target position output by the projection devices can be represented, for example, in the form of lines. The user can then individually adjust the desired position via the application by displacing the line representing the desired position with the finger. The displacement of the desired position can be tracked via the application and optionally readjusted. At the same time, however, the displacement of the setpoint position can also be tracked in real time on the real motor vehicle. This offers the user a simple and convenient way of checking the setting of the desired position directly on the vehicle. For the use of an internal operating unit, the user can remain in the vehicle and does not have to exit the vehicle in order to set the desired position. A software designed for setting the desired position can be preinstalled on the internal operating unit by the manufacturer. In order that the user can take the environment into account during the setting, at least one camera capturing the environment is additionally provided, preferably a camera which is rotatable through 360°, such that the entire environment can be captured. With the aid of this camera, the light projections of the at least one first projection unit and of the at least one second production unit can be captured, so that the display of both the environment and of the vehicle and the light projections can be displayed in the form of lines on the display of the internal operating unit. As also when using the external operating unit, when using the internal operating unit, in addition to setting the line of the desired position which is parallel to the vehicle longitudinal axis, the lines of the desired position which are located in front of and / or behind the vehicle and which define the positions in the direction of the vehicle longitudinal axis can also be set by the user. The user can individually adjust the target position by sliding the line defining the target position with the finger. Here too, the displacement of the desired position can be tracked via the display and optionally readjusted. At the same time, the displacement of the desired position can take place in real time on the real motor vehicle. If the setting of the desired position by the user is completed, the autonomous driving maneuver is preferably executed only when the user has left the motor vehicle. Although these examples are used to explain situations in which an autonomous driving maneuver can be used for parking with the aid of the projection system, the motor vehicle can of course also be removed from the parking space again autonomously via the same steps explained.In a development, a release command for carrying out the autonomous driving maneuver can be issued on the user side via the external operating unit and / or internal operating unit. This offers the advantage that the user retains the final control over the autonomous driving maneuver and it can be certain that the vehicle does not start without confirmation. Here too, different alternatives are possible again. The user can give both the setting of the desired position and the release command either via the external or the internal operating unit. However, it is also possible for the user to set the desired position, for example, via the internal operating unit, but to output the release command for carrying out the autonomous driving maneuver via the external operating unit.In addition, the autonomous driving maneuver can be carried out as a function of information relating to an occupancy state of the motor vehicle and / or a closing state of the motor vehicle and / or an adjustable time specification. These alternatives allow for individual adaptation to the user's needs. For example, it is possible to set whether persons may or may not be located within the motor vehicle during the driving maneuver, wherein the driving maneuver is preferably carried out when there are no persons in the vehicle. In addition, it can be set by the user whether the driving maneuver is to be carried out in the case of an open or closed state of the vehicle, a closed state being preferred. This offers the advantage that during the parking process the vehicle is already locked and the user does not forget to close his vehicle. Furthermore, it is possible that a time specification within which the driving maneuver is to be carried out is freely adjustable or is adjustable at specific time intervals, for example in 5 minute steps. For example, the driving maneuver can be carried out only 5 minutes after the release command when the user desires, wherein a timer starts, for example, when it is detected that the vehicle is locked or no longer there are persons in the vehicle. After completion of the driving maneuver, but also when the driving maneuver is interrupted due to an unpredictable circumstance, a notification to its desired external operating unit can be sent to the user.The invention also relates to a method for automatically manoeuvring a motor vehicle into a parking position, wherein the motor vehicle has a projection system comprising at least one first and at least one second projection device, a detection device and a control device, having the following steps:projecting at least one first light projection, which defines an actual position of the stationary motor vehicle, by means of the at least first projection device into the environment of the motor vehicle,projecting at least one second light projection, which defines a setpoint position, which defines the parking position of the motor vehicle, by means of the at least second, adjustable projection device into the environment of the motor vehicle,controlling the at least second, adjustable projection device by a user for adjusting the desired position,detecting a deviation between the actual position and the desired position via a detection device,determining control parameters via a control device on the basis of the deviation determined by the detection device,automatically maneuvering the motor vehicle on the basis of the control parameters.All method- and device-specific features disclosed for the motor vehicle according to the invention naturally also apply to the motor vehicle disclosed in the method. This applies equally to all alternative embodiments described and to all combinations thereof, as long as they are not incompatible.Further advantages and details of the present invention are evident from the exemplary embodiments described below, and on the basis of the drawings. The individual method steps will also be discussed in more detail here. The following are shown: FIG. 1 shows a schematic schematic schematic illustration of a motor vehicle according to the invention, in which an exemplary embodiment of a method according to the invention is carried out, wherein the setpoint position is not set and the motor vehicle is not in the parking position, FIG. 2 shows the motor vehicle and the exemplary embodiment according to FIG. 1, wherein the setpoint position has been adjusted by the user, FIG. 3 shows the motor vehicle and the exemplary embodiment according to FIGS. 1 and 2, wherein the motor vehicle which has carried out the autonomous driving maneuver and is located in the parking position, FIG. 4 shows a block diagram of the method sequence.FIG. 1 shows a motor vehicle 1 according to the invention, configured to carry out method 2 according to the invention, motor vehicle 1 being in a starting position and not yet in parking position 4 desired by user 3. In this exemplary embodiment, the user 3 would like to approach his motor vehicle 1 towards the wall 5 and park it perpendicularly thereto, so that the bumper in the front region of the motor vehicle 1 is substantially parallel to the wall 5. In order to make this possible, the projection system 6 is activated in order to project the at least one first light projection 7 which defines the actual position 8 by means of the at least one first projection device 22, and to project the at least one second light projection 9 which defines the desired position 10 into the environment of the motor vehicle 1 by means of the at least one second projection device 23.The at least one first projection device 22 and the at least one second projection device 23 are preferably located in at least one side mirror 11 of the motor vehicle 1. in FIG. 1, both projection devices 22, 23 are located in each case in both side mirrors 11. If, for example, the user 3 wishes to maneuver the motor vehicle 1 to the left relative to the vehicle longitudinal axis, as shown in FIG. 1, in order to enter a parking position 4 between the walls 5, the user 3 can activate the projection devices 22, 23 on the left side mirror 11. The two light projections 7, 9 are preferably output in the form of lines 20 with the smallest possible lateral offset with respect to the vehicle longitudinal side of the motor vehicle 1. If the user 3 has not yet set the at least one second light projection 9 of the desired position 10, it is located, as can be seen in FIG. 1, in a starting position next to the at least one first light projection 7 of the actual position 8.During this sequence, the user 3 is preferably located outside the motor vehicle 1 in order to set the setpoint position 10 or to give the release command for the autonomous driving maneuver via the external operating unit 12. However, it is also possible for the user 3 to be located within the motor vehicle 1 for this purpose and to give the corresponding settings or commands via an internal operating unit. If the user 3 is located outside the motor vehicle 1, an application which is designed for controlling the light projection 9 which defines the setpoint position 10 can be loaded onto the external operator control unit 12 desired by the user 3. In the case where the user 3 performs the setting via the internal operating unit, the corresponding software can already be preinstalled on the internal operating unit by the manufacturer. In both cases, the motor vehicle 1, its environment and both the actual position 8 and the desired position 10 can be represented in the form of lines in at least simplified form within the application or the preinstalled software. The user 3 can then move the line representing the desired position 10 on the display into the desired position with the finger. The displacement of the line can be tracked by the user via the application or the preinstalled software and optionally readjusted. At the same time, the displacement also takes place in real time, so that the line 20 representing the setpoint position 10 can also be tracked by the user 3 on the real motor vehicle 1. In addition, the line 30 of the desired position 10, which is oriented parallel to the vehicle front, and the line 31 of the desired position 10, which is oriented parallel to the vehicle rear, and define the positions in the direction of the vehicle longitudinal axis, can also be displayed via the external operating unit 12 or internal operating unit and can be individually set by the user 3.FIG. 2 shows the next step of method 2. In this case, the user 3 has set the at least one second light projection 9, which defines the desired position 10, via the external operating unit 12. An environment detection device 19 can determine environment detection information, on the basis of which the light projections 7, 9 can be adapted to the given circumstances. In the case of a strong sunny and thus high brightness, for example, the color intensity and / or also the color of the lines 20 could be automatically adjusted for better visibility for the user 3. As can be seen in FIG. 2, the new desired position 10 has been set in such a way that it leads close to the wall 5 and marks the parking position 4 desired by the user 3. In this case, the angle of the second light projection 9, starting from the same second light projection 9 of FIG. 1, was also changed. The at least one first light projection 7, which defines the actual position 8, remains unchanged with a slight lateral offset parallel to the vehicle longitudinal side of the motor vehicle 1. The user-side setting of the setpoint position 10 thus leads to a deviation between the actual position 8 and the new setpoint position 10, which marks a parking position 4. This deviation can be determined by the detection device 15, which is preferably optical sensors, a camera or a camera system comprising a plurality of individual cameras. At the same time, a surroundings detection device 16 can detect surroundings information relating to an obstacle in the surroundings of the motor vehicle 1. This environment detection device 16 can be, for example, distance or proximity sensors such as ultrasonic, radar or lidar sensors.In the example shown in FIG. 2, the environment detection device 16 detects the wall 5 as an obstacle 17. a control device 18 is in turn configured in such a way that, as a function of the information which it receives from the detection device 15 and the environment detection device 16, it can ascertain control parameters for the autonomous manoeuvring of the motor vehicle 1 into the parking position 4, via which the motor vehicle can manoeuvre within the scope of the manoeuvre, wherein in this case a multiple forward and backward movement is possible in order to reach the end position.FIG. 3 shows the motor vehicle 1 according to the invention, wherein the motor vehicle 1 has carried out the autonomous driving maneuver and is located in the parking position 4. After the user 3 has set the setpoint position 10 via the external operating unit 12 and the control device 18 has determined the control parameters, the user 3 can issue a release command for the autonomous driving maneuver via the external operating unit 12. In addition, the user 3 can set under what conditions the autonomous driving maneuver should take place. For example, it can be set by the user whether the motor vehicle 1 is open or closed during the driving maneuver, wherein a closed state is preferred. Furthermore, it can also be set whether persons may be located within the motor vehicle 1 during the driving maneuver, provided that the driver assistance system is not designed from the home in such a way that the maneuver can only take place if there are no persons in the vehicle, or in which time period the driving maneuver is to take place. If the user desires this, he can set, for example, that the autonomous driving maneuver takes place at a certain point in time after the output of the release command. As soon as the user 3 has issued the release command and starts the autonomous driving maneuver, a permanent comparison takes place during the entire driving maneuver between the depicted setpoint position 10, which was set by the user 3 via the external operating unit 12 and on the basis of which the control device 18 has calculated the control parameters, and the position in which the motor vehicle 1 is located at any point in time of the driving maneuver. In addition, it is also possible for the setpoint position 10 to be defined and localized using GPS data, so that the control device 18 can additionally check, using these data, whether the motor vehicle 1 is in the desired parking position 4. However, when a driving maneuver is carried out, even when the driving maneuver is interrupted due to unpredictable circumstances, the user 3 can have a notification sent to his desired external operating unit 12.FIG. 4 shows a block diagram 21 of the method sequence according to the invention. In a first step 24, after activation of the projection system 6, the at least one first projection device 22 projects the at least one first light projection 7 defining the actual position 8 into the environment of the motor vehicle 1. the actual position 8 marks the stationary motor vehicle 1 in this case. in the second step 25, the at least one second projection device 23 projects the at least one second light projection 9 defining the desired position 10 into the environment of the motor vehicle 1. as long as the user 3 has not yet set the at least one second light projection 9 via an external operating unit 12 or an internal operating unit, the latter is located in the immediate vicinity of the at least one first light projection 7. in the third step 26, the user 3 can adjust the at least one second light projection 9 such that a desired position 10 results which marks a parking position 4, for example. In fourth step 27, the deviation between actual position 8 and setpoint position 10 may be ascertained via a detection device 15. At the same time, a surroundings detection device 16 can ascertain surroundings detection information relating to obstacles 17 in the surroundings of the motor vehicle 1. In the fifth step 28, a control device 18 can determine control parameters for carrying out the autonomous driving maneuver of the motor vehicle 1 on the basis of the information determined by the detection device 15 and the environment detection device 16. In the sixth and last step 29, after a release command by the user 3, the autonomous driving maneuver of the motor vehicle 1 can be carried out via the external operating unit 12 or the internal operating unit.
