Description

[0001] The invention relates to a method for outputting a starting area for a parking process of a motor vehicle, an electronic computing device for a motor vehicle and a motor vehicle.

[0002] From DE 11 2016 005 614 T5, a parking assistance device is already known, comprising an image sensor that captures an image of the surroundings of the vehicle, and a display unit that presents a guidance image for directing the vehicle from a starting parking position to a destination parking position. Furthermore, the parking assistance device includes a parking aid generation unit that generates parking guidance information showing a parking route based on basic information containing an image from the sensor, the starting parking position, and the destination parking position. The parking assistance device also includes a driving area determination unit that determines a driving area within which the vehicle can travel based on the parking information.Furthermore, the parking assistance device includes a display control that generates an image on the display unit showing the driving area together with the guide image based on the parking guidance information.

[0003] Furthermore, DE 10 2019 208 788 A1 discloses a motor vehicle with a tracking module for determining the vehicle's position. The vehicle includes a communication interface for reading parking space information, wherein the parking space information includes the position of the parking space and advantageously its size. The vehicle includes a tracking module for determining the position of the parking space relative to the vehicle's position, as well as an image generator for determining the position of a virtual image element representing a parking space on a see-through display, depending on the parking space's position relative to the vehicle's position.

[0004] German patent DE 10 2017 111 880 A1 relates to a method for assisting a driver of a motor vehicle with parking, in which a parking space is measured by means of at least one detection device of the motor vehicle and a starting position of the motor vehicle for the parking maneuver into the parking space is determined depending on the measurement of the parking space. The starting position represents the starting point of a trajectory along which the vehicle can be parked in the parking space. The starting position can be displayed by means of a display unit (such as a head-up display).

[0005] Furthermore, DE 10 2009 040 372 A1 discloses a method for carrying out at least a semi-autonomous parking maneuver of a motor vehicle using a driver assistance device. In this process, a control unit calculates an area for a starting position of the passenger car, such that if a reference point of the passenger car is located within this area, the passenger car can be parked in the parking space in one smooth operation.

[0006] The object of the present invention is to provide a solution which makes it possible to guide a driver to a particularly advantageous starting position for a parking maneuver in a particularly simple way.

[0007] This problem is solved according to the invention by the subject matter of the independent claim. Further possible embodiments of the invention are disclosed in the dependent claims, the description, and the figures.

[0008] The invention relates to a method for displaying a starting area for a parking maneuver of a motor vehicle. The method provides that, for at least one identified parking space, the starting area for the motor vehicle is determined on a roadway, from which a single-move parking maneuver into the parking space is possible. This means that the starting area for the motor vehicle is determined by an electronic computing device based on sensor data, and the motor vehicle can park in the parking space in a single move when positioned within the starting area. Furthermore, the method provides that the starting area is displayed superimposed on the roadway within the driver's field of vision. This means that the starting area is displayed on the actual roadway. The driver's field of vision is therefore not represented on a map of the roadway on a display device.For a driver, the starting area appears to be clearly marked on the roadway directly in the vicinity of the vehicle. This makes it particularly easy for the driver to estimate the distance the vehicle needs to travel to reach the starting area. The method makes it especially clear to the driver where the starting area is located in relation to the vehicle. This effectively assists the driver when approaching and parking the vehicle within the starting area.

[0009] Furthermore, the invention provides that individual starting areas are determined for different parking spaces, and all determined starting areas are displayed as a summed total area. Thus, a starting area can be displayed as the total area for the multiple parking spaces, whereby, if the vehicle is positioned within the starting area, parking in one of the parking spaces is possible in a single maneuver. This makes it particularly easy for the driver to be informed where the vehicle should be positioned on the roadway, especially within the total area, to enable particularly easy parking in one of the parking spaces, and in particular, parking in one of the parking spaces in a single maneuver.

[0010] In a further embodiment of the invention, the starting area is projected onto the windshield of the vehicle using augmented reality and displayed within the driver's field of vision. This allows the starting area to be integrated into the driver's field of vision via augmented reality. The driver can thus clearly see the starting area while keeping their eyes on the road ahead. This prevents the driver's attention from being diverted from the road on which the vehicle is traveling.

[0011] In a further embodiment of the invention, the field of view is determined based on the driver's eye level and gaze direction. In other words, the system determines the driver's eye orientation, their perspective of the vehicle's surroundings, and / or the driver's head and / or eye position relative to the starting area. The starting area is then defined within the field of view based on the determined eye level and gaze direction. This allows for particularly good visibility of the starting area for the driver.

[0012] In a further embodiment of the invention, it is provided that the starting area is displayed in the driver's field of vision by means of laser beams projected onto the roadway.

[0013] In other words, the vehicle can be equipped with a laser device that illuminates the roadway within the determined starting area with laser beams. These laser beams mark the starting area on the roadway. Using this laser-marked starting area, the driver can accurately estimate the vehicle's relative position to the starting area, thus guiding the vehicle into the starting area with particular ease and precision.

[0014] In a further embodiment of the invention, the starting area is displayed as a flat, clearly defined area of ​​the roadway. This makes it particularly easy for the driver to see how far the starting area extends on the roadway and how the vehicle must be positioned to be completely within the starting area. This provides the driver with particularly good support when maneuvering the vehicle into the starting area.

[0015] In a further embodiment of the invention, it is provided that, in addition to the starting area, an area to be traversed by the vehicle during the parking maneuver, starting from the starting area and entering the parking space, is displayed. This area can be represented by a trajectory to be followed by the vehicle from the starting area into the parking space. Based on this displayed area to be traversed, the driver can assess whether a collision with an object is likely to occur when parking the vehicle from the starting area into the parking space. In particular, the starting area can be determined by means of an electronic computing device in the vehicle in such a way that a collision with an object is avoided when parking the vehicle in a single maneuver within the area to be traversed.This can significantly reduce the risk of accidents when parking the vehicle.

[0016] In a further embodiment of the invention, a symbol is displayed superimposed on the parking space in the driver's field of vision. For parking the vehicle from the starting area into the parking space in one maneuver, the symbol represents a determined, anticipated orientation of the vehicle within the parking space. The symbol can represent and depict the vehicle in its anticipated, parked state. For example, the symbol can be an image of the vehicle in the parking space. The symbol allows the driver to clearly see how the vehicle is oriented within the parking space after the parking maneuver, starting from the starting area.Additionally, the driver of the motor vehicle can use the symbol to determine whether the vehicle is to be parked in the parking space in a forward parking maneuver or in a reverse parking maneuver, starting from the starting area.

[0017] In this context, it may be particularly suitable for the symbol to be displayed as a hologram superimposed on the parking space in the driver's field of vision. This allows the driver of the vehicle to better estimate the three-dimensional dimensions of the vehicle when parked in the space, provided the hologram represents an image of the vehicle.

[0018] In this context, it can also be provided that the symbol representing the vehicle's orientation in a parking space is adjusted based on user input, and that the determined starting area is adjusted based on the adjusted orientation represented by the adapted symbol. In other words, the driver can adjust the intended orientation of the vehicle in the parking space via user input, for example, by changing the orientation of the symbol displayed in the parking space, particularly by rotating it. This allows the driver, for instance, to indicate that they wish to park the vehicle forwards instead of reversing into the parking space. Thus, the driver can adjust the vehicle's position in the parking space to reflect the planned orientation of the vehicle.The determined starting area is adjusted to the vehicle's orientation within the parking space, enabling a single-pass parking maneuver in which the vehicle is positioned in the space according to the user's input. By adjusting the symbol's orientation, the driver can set the final position of the vehicle after parking. This allows the parking process to be precisely tailored to the driver's preferences.

[0019] In a further embodiment of the invention, the starting area is determined based on at least one identified obstacle in the vicinity of the parking space and / or the width and / or length of the parking space and / or the orientation of the parking space. By determining the starting area based on the at least one identified obstacle in the vicinity of the parking space, it can be ensured that the risk of collision between the vehicle and the obstacle is minimized when parking the vehicle in a single maneuver from the identified starting area into the parking space.Determining the starting area based on the width and / or length of the parking space and / or its orientation (e.g., parallel or perpendicular) allows for a high probability of parking the vehicle in the space in a single maneuver from its position within the starting area. This results in a particularly simple parking maneuver.

[0020] In a further embodiment of the invention, it is provided that, when the motor vehicle is positioned in the starting area, it is moved into the parking space by means of assisted parking or manual parking. With assisted parking, the motor vehicle can be steered laterally, at least by means of a control unit, and optionally also longitudinally by the control unit during the parking maneuver from the starting area into the parking space. Alternatively, the driver can manually park the motor vehicle from the starting area into the parking space, particularly in one maneuver. Assisted parking provides the driver with particularly good support when parking the motor vehicle into the parking space.When manually parking a vehicle, the driver can be particularly well supported in a single-pull parking maneuver by displaying the starting area.

[0021] In a further embodiment of the invention, it is provided that, depending on a user input received, a parking space is selected from several available spaces, and the starting area for the selected parking space is determined and displayed. In other words, an electronic computing device in the vehicle can identify several parking spaces in the vicinity of the vehicle. These identified parking spaces can be displayed to the driver, thus providing the driver with particularly good information about the available spaces. Using the user input, the driver can then select the parking space in which the vehicle is to be parked from among the identified spaces.For this selected parking space, the starting area can be determined using the electronic computing device, and then the output of the starting area can be triggered. This provides particularly good support to the driver when parking the vehicle in one of several parking spaces.

[0022] The invention further relates to an electronic computing device for a motor vehicle, which is configured to perform a method as already described in connection with the inventive method for displaying the starting area for the parking process of the motor vehicle. For this purpose, the electronic computing device can be configured to determine a starting area for the motor vehicle on a roadway for at least one identified parking space, from which a single-move parking maneuver into the parking space is possible. Furthermore, the electronic computing device can be configured to trigger the display of the starting area superimposed on the roadway within the driver's field of vision.

[0023] Furthermore, the invention relates to a motor vehicle with an electronic computing device, as already described in connection with the electronic computing device according to the invention. Advantages and advantageous further developments of the method according to the invention are to be regarded as advantages and advantageous further developments of the electronic computing device and the motor vehicle, and vice versa.

[0024] Further features of the invention may become apparent from the following description of the figures and from the drawings. The features and combinations of features mentioned above in the description, as well as the features and combinations of features shown below in the description of the figures and / or in the figures themselves, can be used not only in the combinations specified, but also in other combinations or individually, without departing from the scope of the invention.

[0025] The drawing shows in: Fig. 1. A schematic view from the driver's area of ​​a motor vehicle into the surroundings of the motor vehicle in which several parking spaces are available for the motor vehicle, wherein a starting area for initiating a parking maneuver of the motor vehicle is shown superimposed on the roadway within the driver's field of vision; and Fig. 2 a procedural scheme for a procedure for outputting the starting area for the parking process of the motor vehicle.

[0026] Identical or functionally equivalent elements are marked with the same reference symbols in the figures.

[0027] In Fig. Figure 1 shows a view from the cockpit of a motor vehicle 1 into its surroundings 2. The view is directed specifically from the driver's area towards a roadway 3 located in front of the motor vehicle 1 in its surroundings 2. On the roadway 3, a starting area 4 is marked within the driver's field of vision. From this starting area, the motor vehicle 1 can maneuver into a parking space 5 associated with the starting area 4 in a single step. This starting area 4 is projected into the driver's field of vision via augmented reality through the windshield of the motor vehicle 1. Furthermore, an area 6 on the roadway 3, which the motor vehicle 1 must drive over, is marked within the driver's field of vision. The motor vehicle 1 drives over this area when maneuvering from the starting area 4 into the parking space 5.

[0028] In Fig. Figure 2 shows a process diagram for a procedure for displaying a starting area for a parking maneuver of motor vehicle 1. This procedure can be carried out using an electronic computing device in motor vehicle 1. In the procedure, in a first step V1, the starting area 4 for motor vehicle 1 is determined on the roadway 3 for at least one identified parking space 5. From this starting area 4, motor vehicle 1 can park in the parking space 5 in a single maneuver. In a second step V2, this determined starting area 4 is displayed superimposed on the roadway 3 within the driver's field of vision of motor vehicle 1. Alternatively, instead of being displayed via augmented reality using a laser device, the field of vision can be marked directly on the roadway 3 using laser beams.The starting area 4 is presented here as a flat, delimited area on the roadway 3 within the field of vision of the driver of motor vehicle 1. As in . Fig. In addition to the starting area 4, the area 6 to be driven over by the motor vehicle 1 during the parking process, starting from the starting area 4 into the parking space 5, can be displayed superimposed on the roadway 3 and placed in the driver's field of vision.

[0029] The driver's field of vision in vehicle 1 can be determined, in particular, based on the driver's eye level and direction of gaze. For this purpose, the driver's area can be monitored using a driver observation camera to determine the driver's eye level and direction of gaze from the image data recorded by the camera. To prevent a collision between vehicle 1 and an obstacle during the parking maneuver, the starting zone 4 can be determined based on at least one detected obstacle in the vicinity 2 of vehicle 1 or in the vicinity of the parking space 5. Alternatively or additionally, the starting zone 4 can be determined based on the length and / or width of the parking space 5 and / or its orientation.

[0030] If several possible parking spaces 5 are identified for the vehicle 1, particularly by means of the vehicle 1's electronic computing unit, then, depending on user input received from the driver indicating the selection of one of the identified parking spaces 5, the parking space 5 designated as the target parking space for the vehicle 1 can be selected. Depending on the target parking space identified from the multiple parking spaces 5, the starting area 4 for this selected target parking space can be determined and displayed. Alternatively or additionally, the respective starting area 4 can be determined for all parking spaces 5 identified in the vicinity 2, and each of the starting areas 4 can be displayed superimposed on the roadway 3 within the driver's field of vision. For this purpose, all identified starting areas 4 for the identified parking spaces 5 can be displayed as a summed total area.

[0031] Once the motor vehicle 1 is positioned in the starting area 4, the motor vehicle 1 can be parked in the parking space 5 assigned to the starting area 4 in a single maneuver using assisted or manual parking.

[0032] To inform the driver of vehicle 1 about the expected orientation of the vehicle 1 after the single-stage parking maneuver from the starting area 4 into parking space 5, a symbol can be displayed superimposed on parking space 5 in the driver's field of vision. This symbol represents the expected orientation of vehicle 1 in parking space 5. In particular, this symbol can be a hologram in the shape of vehicle 1. A further user input from the driver of vehicle 1, indicating a change in the desired orientation of vehicle 1 in parking space 5, can be received via an input device in vehicle 1 or a mobile electronic device.As a result of receiving further user input, the symbol representing the orientation of vehicle 1 in parking space 5 can be adjusted depending on this input. Furthermore, the starting area 4 assigned to parking space 5 is adjusted based on the anticipated orientation of vehicle 1 in parking space 5. Thus, the starting area 4, intended for the orientation of vehicle 1 in parking space 5 as desired by the driver, can be displayed. From this starting area, vehicle 1 can be parked in parking space 5 in a single maneuver, with the final orientation of vehicle 1 in parking space 5 determined by the driver's further input.

[0033] The motor vehicle 1 can include an augmented reality output device by means of which the starting area 4 can be projected into the windshield of the motor vehicle 1 in the driver's field of vision using so-called augmented reality.

[0034] The described procedure is based on the understanding that the performance of assisted parking systems is significantly dependent on the starting position from which the vehicle enters the respective parking space 5. The longitudinal and lateral distances of the vehicle 1 to the parking space 5, as well as the lateral distance to stationary objects such as other parked vehicles, can be crucial. Under ideal conditions, a parking assistant can perform a single-stage parking maneuver from the starting position without any corrective movements or repositioning of the vehicle 1, thus ensuring that the vehicle 1 is parked quickly and precisely in the designated parking space 5.

[0035] The process involves projecting an optimal starting area for vehicle 1 onto a ground plane in front of the potential parking space 5, specifically via augmented reality in the windshield of vehicle 1, or by laser projection onto the road ahead. Within the driver's field of vision, the starting area 4, from which parking space 5 can be accessed in a single maneuver, and the calculated area 6 to be traversed by vehicle 1 on its way from starting area 4 to parking space 5 are displayed, thus visualizing a planned trajectory and a planned target position for vehicle 1. Furthermore, a three-dimensional hologram of vehicle 1 in parking space 5 can be displayed, so that it appears to the driver of vehicle 1 as if their vehicle 1 is already parked in parking space 5.This allows the driver to see particularly well what orientation the vehicle 1 is likely to have in parking space 5 after the parking procedure.

[0036] Overall, the invention demonstrates how the starting area 4 for the motor vehicle 1 can be displayed using augmented reality. Reference symbol list 1 motor vehicle 2 Environment 3 lanes 4 Starting area 5 parking spaces 6 areas to be driven over V1 to V2 respective process steps
