Description

Technical Field

[0001] The present disclosure generally relates to a parking assist system for a vehicle, a method for operating a parking assist system, and a vehicle. Background Art

[0002] Many vehicles today have parking assistance systems, which for example include parking sensors, in order to assist the driver with a parking maneuver or to allow a parking maneuver to be performed independently (autonomously). However, such parking assistance systems, and in particular the parking sensors connected thereto, are not yet a matter of course. A large proportion of vehicles do not have such sensors. This means that even if a vehicle with the described parking assistance system is equipped to assist with a parking maneuver of said vehicle, a parking maneuver performed by another vehicle without such a parking assistance system may still result in a potentially critical situation even for the vehicle with the parking assistance system. Furthermore, despite the fact that a considerable proportion of vehicles already have parking assistance systems installed, a parking maneuver of a vehicle without a parking assistance system is still "unassisted".

[0003] US 9514646 B2, US 10882521 B2 and US 7498954 B2 disclose methods for operating a parking assistance system for a parked stationary vehicle, wherein sensor data of the stationary vehicle or other sensor data is wirelessly transmitted to the vehicle being parked to assist the parking maneuver. However, these methods require complex communication infrastructure and protocols. Therefore, these methods are complex and disadvantageous.

[0004] Therefore, there is a need to overcome or at least reduce the disadvantages of known parking assistance systems or methods of operation thereof. In particular, there is a need to provide a parking assistance system and method of operation thereof and a vehicle that allow parking maneuvers without complex and expensive communication infrastructure. Summary of the invention

[0005] This object is achieved by the subject matter of the independent claims. Advantageous embodiments are indicated in the dependent claims and in the following description, each of which can represent aspects of the disclosure independently or in (sub)combination. Some aspects are described for the device, others for the method. However, these aspects are transferable to one another.

[0006] According to one aspect, some embodiments relate to a parking assistance system for a vehicle, in particular a host vehicle. The parking assistance system has at least one sensor and a feedback control device connected to the at least one sensor. The parking assistance system is at least designed to detect a parking maneuver of a second vehicle into a parking space adjacent to the host vehicle by means of the at least one sensor. The parking assistance system is also designed to provide maneuver information about the parking maneuver that can be perceived by the second vehicle by means of at least one signal transmitter of the host vehicle.

[0007] A parking assistance system is thus provided which is advantageously managed without a complex communication structure and which is nevertheless able to assist a parking maneuver of a vehicle which itself does not have a parking assistance system. This increases the reliability of the parking maneuver of a vehicle which itself does not have a parking assistance system. The maneuver information can advantageously be made known to the second vehicle in an intuitive manner via at least one signal transmitter of the host vehicle, without the need for complex equipment.

[0008] In the present case, a parking assistance system is understood to be a system which assists the parking maneuver, for example by providing the driver with certain sensor data or even taking over certain driving functions, such as specifying the steering angle. Alternatively, the parking assistance system can also be designed to be able to perform the parking maneuver independently (autonomously). The parking assistance system also takes over the speed control.

[0009] In the present case, the host vehicle is understood to be a vehicle including a parking assistance system.

[0010] In the present case, the second vehicle is understood to be a vehicle other than the host vehicle. In particular, the second vehicle does not need to have a parking assistance system or corresponding sensors, nor does it need to have any communication infrastructure.

[0011] A parking space is understood to be an empty space adjacent to a host vehicle, into which the vehicle can be driven and in which it appears suitable or suitable to be parked.

[0012] In the present case, a parking maneuver is understood to be a trajectory or a movement path of the second vehicle for moving the second vehicle into the parking space.

[0013] The feedback control device receives sensor data detected by at least one sensor respectively, and provides manipulation information for the signal transmitter based on the sensor data. Generally, the feedback control device includes at least one data processing device.

[0014] In the present case, the maneuvering information is understood to be information related to the parking maneuver of the second vehicle. For example, the maneuvering information may include a notification of the presence of the host vehicle or distance information, etc.

[0015] Preferably, the feedback control of the parking assistance system can be designed to communicate with the feedback control of the host vehicle and prompt the control to provide maneuvering information via at least one signal transmitter of the host vehicle. This means that the signal transmitter does not have to be part of the parking assistance system, but can only be part of the host vehicle as a whole. The control of the signal transmitter can be assumed by the control of the host vehicle as a whole. For providing the maneuvering information, the feedback control of the parking assistance system can additionally communicate with the control of the host vehicle accordingly. This means that the feedback control only outputs signals indirectly via the signal transmitter.

[0016] Optionally, the parking assistance system is also designed to detect an intended parking maneuver of a second vehicle. This can occur, for example, by identifying a second vehicle parked near or in the immediate vicinity of the respective parking space via at least one sensor. The second vehicle can be identified, for example, because the second vehicle has been parked in a position that serves as a starting point for a forward or reverse parking maneuver, respectively. This enables assistance to be provided via the parking assistance system throughout the entire parking maneuver of the second vehicle. For example, the second vehicle can thus also be aware of the assistance provided by the parking assistance system of the host vehicle during the parking maneuver.

[0017] In some embodiments, the parking assistance system is further designed to activate further sensors of the parking assistance system after a parking maneuver or an expected parking maneuver of a second vehicle is detected. In other words, the parking assistance system can be switched from a monitoring state to an awake state, in which the full functionality of the parking assistance system is implemented by using all or at least a plurality of sensors included in or connected to the host vehicle. This reduces energy consumption in the monitoring state, while the full functionality of the parking assistance system is used once a parking maneuver or an expected parking maneuver of a second vehicle is detected.

[0018] Optionally, the parking assistance system is also designed to determine at least one dimension of the parking space by means of at least one sensor. A robust decision basis is thereby established in order to be able to assess whether the parking maneuver of the second vehicle is successful.

[0019] Preferably, the parking assistance system is also designed to determine at least one dimension of the second vehicle by means of at least one sensor. This further increases the robustness of the decision basis in order to be able to assess whether a parking maneuver of the second vehicle is successful. In particular, the dimensions of the second vehicle can be compared with the dimensions of the parking space in order to be able to assess whether the parking maneuver is successful. Alternatively, it can be assessed how the parking maneuver should be carried out in order to be successful.

[0020] In some embodiments, the parking assistance system is designed to provide varying maneuvering information based on the distance information about the second vehicle by means of at least one signal transmitter. For this purpose, for example, the pulse frequency of the signal transmitter for providing the maneuvering information can be varied. Alternatively, the intensity of the signal provided by the signal transmitter can also be varied. In another alternative, the signal transmitter can also have a plurality of separate output devices so that varying maneuvering information can be provided via a signal sequence or a series of signals, which is ensured by separate output devices.

[0021] In some embodiments, the manipulation information is provided visually or acoustically by the signal transmitter. Thus, manipulation information with different meanings can be provided in a simple and intuitive manner.

[0022] Preferably, the maneuver information may indicate whether the size of the parking space is sufficient for a successful parking maneuver of the second vehicle. Thus, the driver of the second vehicle may be made directly aware of whether the parking maneuver is feasible.

[0023] Alternatively, the maneuver information may indicate whether a minimum distance between the host vehicle and the second vehicle has not been reached.

[0024] In an alternative, the maneuver information may also indicate whether a minimum distance between the second vehicle and the third vehicle has not been reached.

[0025] The maneuvering information can therefore provide, in particular, information about the possibility of contact between the second vehicle and the host vehicle or the third vehicle.

[0026] Optionally, the manipulation information can also be changed so that the signal output by the signal transmitter has different components. For example, the signal can be output essentially visually by means of the output device of the signal transmitter. If the minimum distance is not reached, the signal can be additionally changed so that it also has an acoustic component. Thus, the variability of the meaning of the signal output by means of the signal transmitter can be advantageously increased, for example to include additional information content.

[0027] In this case, the third vehicle is understood to be another vehicle different from the main vehicle and the second vehicle. For example, the third vehicle can be positioned near a parking space.

[0028] In some embodiments, at least one sensor includes at least one of a front environment detection device of the main vehicle, a rear environment detection device of the main vehicle, a front parking sensor, and a rear parking sensor. For example, the environment detection device and / or parking sensor herein may include a camera, a radar device, a LiDAR device, an ultrasonic device, an infrared device, etc. Therefore, the environment of the main vehicle can be detected in a variety of ways. In the monitoring state of the parking assistance system, only a single sensor or only a part of all sensors needs to be activated. In the awake state, a larger number of sensors (especially all sensors) can be used to detect and evaluate the environment and especially the parking maneuver of the second vehicle.

[0029] Optionally, at least one signal transmitter includes at least one light output device and a sound output device. For example, the light output device and the sound output device are already components of the host vehicle, which are originally used for normal driving functions. This means that the parking assistance system does not necessarily require a separate signal transmitter. Instead, the existing signal transmitter of the host vehicle can be used to provide manipulation information. Specifically, the signal transmitter may include, for example, headlights, taillights, sidelights, indicators, etc. For example, the horn of the host vehicle that exists in any case can be used as a sound output device. The varying manipulation information can be provided by changing the intensity or pulse frequency, or by changing the output sequence of the signal output by the signal transmitter, or by using a plurality of separate output devices of the signal transmitter.

[0030] Preferably, the sound output device can be an internal sound output device of the vehicle or an external sound output device of the vehicle. For example, optionally, an electric vehicle comprises an external sound output device to intentionally output noise, because the electric motor forming the basis of the vehicle itself leads to lower noise emissions than an internal combustion engine. The additional intentional noise emission makes the vehicle more perceptible to the surroundings of the vehicle. In the present case, the maneuvering information can therefore also be provided with the aid of the external sound output device of the vehicle. In this context, the external sound output devices can already be provided for usual vehicle functions, or alternatively, they can be provided in particular for a parking assistance system. Furthermore, the external sound output devices can also be used for both functions.

[0031] For example, the taillights may include a plurality of lights in the form of a light bar. Maneuvering information corresponding to a greater or lesser distance between the second vehicle and the host vehicle or the third vehicle may additionally be provided by a corresponding number of lights.

[0032] Alternatively, a greater or lesser distance may be indicated by the frequency of the signal.

[0033] Preferably, the parking assistance system also has at least one storage device connected to the feedback control device. The parking assistance system is further designed to store a record of the parking maneuver of the second vehicle in the storage device based on sensor data detected by the at least one sensor. In other words, a data set can be stored in the storage device, based on which the parking maneuver of the second vehicle can be reconstructed and tracked (e.g. reproduced). Thus, for example, a tracking mechanism can be provided in the event of a contact between the second vehicle and another vehicle.

[0034] Preferably, the parking assistance system also has at least one communication device. The feedback control device is connected to the communication device. In the event of contact between the second vehicle and another vehicle (e.g. the host vehicle), the parking assistance system is designed to output an alarm via the communication device. For example, the alarm can be transmitted to the owner or owner of the host vehicle.

[0035] Alternatively, the parking assistance system can also be designed to send an alert to the emergency services, for example in the event of a serious contact. Thus, it can be ensured that assistance is provided within a relatively short time.

[0036] In some embodiments, the parking assistance system can also be designed to recognize whether the second vehicle has a parking assistance system, an automatic parking device, a parking assistance device (e.g., a parking sensor), etc. If the second vehicle has a corresponding system or a corresponding device, the parking assistance system of the host vehicle can be designed to avoid providing maneuvering information related to the parking maneuver or to prevent providing the information. Thus, contradictions between different maneuvering information from independent systems of the host vehicle and the second vehicle can be eliminated. In addition, energy of the host vehicle can be saved.

[0037] Preferably, the parking assistance system can be designed to detect the parking assistance system, automatic parking device, parking assistance device, etc. of the second vehicle based on at least one sensor of the host vehicle. For example, at least one sensor of the host vehicle can detect the corresponding system of the second vehicle based on the sound waves or radar waves emitted by the second vehicle.

[0038] Alternatively or additionally, the parking assistance system can also be designed to identify the parking assistance system of the second vehicle, the automatic parking device, the parking assistance device, etc. based on the vehicle-to-vehicle communication. For example, a corresponding communication device of the parking assistance system of the host vehicle can be used for this purpose.

[0039] Despite detecting or identifying the parking assistance system, automatic parking device or parking assistance device, etc. of the second vehicle and thus preventing the output of maneuver information, the parking assistance system of the host vehicle can still be designed to monitor the parking process of the second vehicle and store a record of the parking maneuver of the second vehicle based on sensor data detected by at least one sensor, for example in a storage device. Thus, for example, contact between the host vehicle and the second vehicle can be tracked.

[0040] According to another aspect, some embodiments of the present disclosure also relate to a method for operating a parking assistance system of a host vehicle, the parking assistance system having at least one sensor and a feedback control device connected to the at least one sensor. The method comprises at least the following steps: A parking maneuver (or an anticipated parking maneuver) of a second vehicle into a parking space adjacent to the host vehicle is detected by means of at least one sensor.

[0041] Maneuver information relating to the parking maneuver is provided by means of at least one signal transmitter of the host vehicle, which maneuver information can be perceived by the second vehicle.

[0042] The advantages achieved by the above-described parking assistance system are also achieved in a corresponding manner by the method outlined herein. In particular, a parking maneuver of a second vehicle can be performed and assisted even if the second vehicle itself does not have a parking assistance system. The probability of a successful parking maneuver is thereby increased while the probability of contact between the second vehicle and another vehicle is reduced.

[0043] According to another aspect, some embodiments of the present disclosure also relate to a vehicle having a parking assistance system as described above or a parking assistance system that can be operated according to the method as described above. The advantages achieved by the above parking assistance system are also achieved in a corresponding manner by the vehicle described herein.

[0044] In the context of the present disclosure, vehicles may include in particular land vehicles; i.e. off-road vehicles and road vehicles, such as cars, buses, trucks and other utility vehicles. Vehicles may be manned or unmanned. In addition to pure electric vehicles (BEVs), they may also include hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs) and vehicles with internal combustion engines.

[0045] All features described for each aspect may be combined with other aspects alone or in (sub)combinations. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the described embodiments are not limited to the embodiments shown, but have the maximum possible scope of application compatible with the principles and features disclosed herein.

[0048] All features disclosed with respect to the exemplary embodiments and / or figures may be combined with features of various aspects of the present disclosure (including features of the preferred embodiment) alone or in any sub-combination, provided that the resulting feature combination makes sense to a person skilled in the art.

[0049] For the purposes of the present disclosure, the expression “at least one of A, B, and C” means, for example, (A), (B), (C), (A and B), (A and C), (B and C), or (A, B, and C), including all further possible combinations when more than three elements are listed. In other words, the phrase “at least one of A and B” generally means “A and / or B”, i.e., only “A”, only “B”, or “A and B”.

[0050] Figure 1 A simplified schematic diagram of a vehicle 10 having a parking assist system 12 is shown in accordance with an embodiment of the present disclosure.

[0051] The vehicle 10 includes a parking assistance system 12, which in this case has a plurality of front sensors 14A and rear sensors 14B. The environment of the host vehicle 10 can be detected via the front sensors 14A and rear sensors 14B. The parking assistance system 12 may also optionally have other sensors, such as side sensors.

[0052] The sensor 14 is connected to a control device 16 of the host vehicle 10 . According to this embodiment, a feedback control device 18 of the parking assistance system 12 is designed as a part of the control device 16 . The feedback control device 18 comprises at least one data processing device 20 .

[0053] Alternatively, the control device 16 and the feedback control device 18 may also be separate components.

[0054] Furthermore, a plurality of signal transmitters 22A to 22E are connected to the control device 16. For example, the signal transmitters 22A, 22B are designed as headlights. In contrast, the signal transmitters 22C, 22D are designed as taillights of the host vehicle 10. The signal transmitter 22E mirrors the sound output device, for example to enable the output of a horn signal.

[0055] In the present case, the feedback control device 18 is also connected to at least a storage device 24. The storage device 24 is designed to store data therein.

[0056] Furthermore, the feedback control device 18 of the parking assistance system 12 is connected to a communication device 26 which ensures external communication with a remote receiver.

[0057] As an alternative to the connection described herein, the feedback control device 18 may also be connected directly to the various components, ie, to the sensors 14 and the signal transmitters 22 , via the control device 16 of the host vehicle 10 .

[0058] The sensors 14 need not be dedicated sensors for the parking assistance system 12. They may also be common components of the host vehicle 10 to which the parking assistance system 12 at least indirectly accesses.

[0059] Alternatively or additionally, individual sensors 14 of the parking assistance system 12 may also be provided, which are not originally used for other driving functions of the host vehicle 10 .

[0060] Alternatively or additionally, the signal transmitters 22 may also be provided exclusively for the parking assistance system 12 , such that they are separated from other output devices of the host vehicle 10 .

[0061] Figure 2 A simplified schematic diagram of a method 28 for operating a parking assist system 12 is shown in accordance with an embodiment of the present disclosure. Dashed lines represent optional steps.

[0062] refer to Figures 3 to 5 Explaining method 28 in more detail, Figures 3 to 5 Shown is a simplified schematic diagram of a vehicle configuration that may occur, for example, during a method 28 for operating a parking assist system 12 according to an embodiment of the present disclosure.

[0063] According to this embodiment, the parking assistance system 12 has a monitoring state and an awake state. The monitoring state of the parking assistance system 12 is characterized in that only a single sensor 14 is activated. In this regard, Figure 3 The sensor 14 is shown detecting the environment of the host vehicle 10. A second vehicle 40 approaches the host vehicle 10 and is detected by the sensor 14. The sensor 14 also detects a parking space 42 located in the vicinity of the host vehicle 10 between the host vehicle 10 and a third vehicle 44.

[0064] In step 30, a parking maneuver (or an anticipated parking maneuver) of a second vehicle into a parking space adjacent to the host vehicle 10 is detected by means of at least one sensor 14. Figure 4 The sensor 14 detects the second vehicle 40 based on a position which clearly indicates that the second vehicle 40 intends to perform a parking maneuver into the parking space 42 .

[0065] In step 32, maneuver information related to the parking maneuver is provided by means of at least one signal transmitter 22 of the host vehicle 10, which can be perceived by the second vehicle 40. Figure 4 This is explained by way of example. Figure 4 The signal transmitter 22 is used to assist the second vehicle 40 in performing a parking maneuver. In this case, the distance information of the second vehicle 40 is provided by the changing frequency of the signal output by the signal transmitter 22.

[0066] The method 28 may optionally be developed so that, after step 30, an awake state of the parking assistance system 12 is triggered in an optional step 34. In the awake state, the parking assistance system 12 may be designed to more accurately monitor the environment of the host vehicle 10 using the additional sensors 14 and to assist in the parking maneuver of the second vehicle 40. Thus, a more accurate detection of the parking maneuver may be achieved.

[0067] Switching to the awake state can also be associated, for example, with outputting a signal via the signal transmitter 22, on the basis of which the parking assistance system 12 of the host vehicle 10 makes itself known to the second vehicle 40. Thus, it can be indicated to the second vehicle 40 that the parking assistance system 12 is designed to assist in parking maneuvers. This is also the case in Figure 4 This is explained in the form of examples.

[0068] The method 28 can also be developed so that, in an optional step 36, a record of the parking maneuver of the second vehicle 40 is stored in the storage device 24 of the parking assistance system 12. As a result, for example, the parking maneuver of the second vehicle 40 can also be tracked after the event.

[0069] In some embodiments, the method 28 may also be developed so that, in an optional step 38, a warning is output by the feedback control device 18 of the parking assistance system 12. For example, in the event of a contact between the second vehicle 40 and another vehicle, such as the third vehicle 44, a warning may be output. Purely by way of example, the warning may be transmitted to the owner or owners of the host vehicle 10. For example, the communication device 26 may be used to output the warning. Alternatively or additionally, in the event of a serious contact from the second vehicle 40, an emergency service center may also be alerted.

[0070] Certain embodiments disclosed herein, particularly control device 16, feedback control device 18, sensor 14, storage device 24, and communication device 26, use switching circuits (e.g., one or more switching circuits) to implement the standards, protocols, methods, or techniques disclosed herein, functionally connect two or more components, generate information, process information, analyze information, generate signals, encode / decode signals, convert signals, send and / or receive signals, control other devices, etc. Any type of circuit may be used.

[0071] In one embodiment, the circuit (e.g., feedback control device 18) includes, among other things, one or more data processing devices, such as a processor (e.g., a microprocessor), a central processing unit (CPU), a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), a system on a chip (SoC), etc., or any combination thereof, and may include discrete digital or analog circuit elements or electronic devices or combinations thereof. In one embodiment, the circuit includes a hardware circuit implementation (e.g., an implementation in an analog circuit, an implementation in a digital circuit, etc., and a combination thereof).

[0072] In one embodiment, the switching circuit comprises a combination of a switching circuit and a computer program product with software or firmware commands stored on one or more computer readable memories and cooperating to prompt the device to perform one or more of the protocols, methods, or techniques described herein. In one embodiment, the circuit technology comprises a switching circuit, such as a microprocessor or a component of a microprocessor, which requires software, firmware, etc. to operate. In one embodiment, the switching circuit comprises one or more processors or components thereof and associated software, firmware, hardware, etc.

[0073] In this application, quantities and numbers are mentioned. Unless expressly stated, these quantities and numbers should not be considered restrictive, but should be considered as examples of possible quantities or numbers for the present application. In this regard, in this application, the term "plurality" may also be used to refer to quantities or numbers. In this regard, the term "plurality" refers to any number greater than one, such as two, three, four, five, etc. The terms "for example," "approximately," "close to," etc. refer to plus or minus 5% of a particular value.

[0074] Although the disclosure has been illustrated and described with respect to one or more embodiments, equivalent changes and modifications will occur to others skilled in the art upon the reading and understanding of this specification and the annexed drawings.
