[0002] Driver assistance system and driver assistance procedures for a vehicle

[0003] The present disclosure relates to a driver assistance system for a vehicle, a vehicle with such a driver assistance system, a driver assistance procedure for a vehicle, and a storage medium for executing the driver assistance procedure. The present disclosure relates in particular to a situation-based switching between different sets of functions.

[0004] State of the art

[0005] Driver assistance systems for automated driving are steadily gaining in importance. Automated driving can be implemented with varying degrees of automation. Examples of these levels include assisted, partially automated, conditionally automated, highly automated, and fully automated driving. The five automation levels mentioned above correspond to SAE Levels 1 to 5 of the SAE J3016 standard (SAE - Society of Automotive Engineering) as of April 30, 2021. In fully automated driving (SAE Level 5), the system can perform all aspects of the dynamic driving task (24-0985) under any road and environmental conditions, tasks that a human driver can also handle.

[0006] Driving functions for automated driving are continuously evolving at the aforementioned levels, and new functions are constantly being added. This can lead to complications, especially if certain functions are unfamiliar to the driver or cannot be used in accordance with regulations in certain situations.

[0007] Disclosure of the invention

[0008] The purpose of this disclosure is to specify a driver assistance system for a vehicle, a vehicle with such a driver assistance system, a driver assistance procedure for a vehicle, and a storage medium for executing the driver assistance procedure, all of which enable optimal use of automated driving functions. In particular, the purpose of this disclosure is to maximize the service life of the driver assistance system and thereby increase road safety.

[0009] This problem is solved by the subject matter of the independent claims. Advantageous embodiments are specified in the dependent claims.

[0010] According to an independent aspect of the present disclosure, a driver assistance system for a vehicle, in particular a motor vehicle, is specified.The driver assistance system comprises: a driving module configured for automated driving, wherein the driving module is configured to implement a first set of automated driving functions and a second set of automated driving functions, wherein the first set of automated driving functions and the second set of automated driving functions differ at least partially with respect to a functional aspect of the automated driving functions and / or with respect to a type of automated driving functions; and 24-0985 a selection module configured to select, based on user input and / or based on at least one circumstance parameter, either the first set of automated driving functions or the second set of automated driving functions for automated driving.

[0011] According to the invention, an entire package of driving functions is replaced or reconfigured, for example, by adding new functions, instead of adding or removing individual driving functions. For example, an "old" package of driving functions can be replaced by a "new" package, where the old and new packages comply with different regulations (e.g., ECE-R171, ECE-R13H, ECE-R79, etc.). Unlike adding or removing individual driving functions, this changes the vehicle's fundamental behavior, for example, with regard to speed limits and specific driving behavior, such as during lane changes. Depending on the situation, either the "old" package (e.g., the classic package) or the "new" package (e.g., a newly approved or purchased package) can now be used for automated driving. The result is optimal use of automated driving functions.

[0012] The driving module and the selection module may include software components / algorithms that are set up to run on at least one processor and thereby perform the functionalities of the respective module.

[0013] The driving module and the selection module can be implemented in a single software and / or hardware module. Alternatively, the driving module and the selection module can each be implemented in separate software and / or hardware modules.

[0014] The term “set of automated driving functions,” as used in this disclosure, refers to a defined combination of several (e.g., two or more) automated driving functions that can be designed as a unified package and integrated into a vehicle. This package is predefined and standardized so that, for example, all the included functions can be provided, activated, and used together. 24-0985

[0015] Preferably, the automated driving functions of the first set of automated driving functions and / or the automated driving functions of the second set of automated driving functions include, or relate to, automated longitudinal control. The term "automated longitudinal control" refers to a technology that enables the vehicle to regulate its speed autonomously. This is often achieved through adaptive cruise control (ACC) systems and other driver assistance systems. Such driver assistance systems use various sensors, such as radar, lidar, ultrasound, and / or cameras, to gather information about the vehicle's surroundings. Based on this data, the vehicle can then accelerate and decelerate autonomously without driver intervention.

[0016] Preferably, the automated driving functions of the first set of automated driving functions and / or the automated driving functions of the second set of automated driving functions include, or relate to, automated lateral control. The term "automated lateral control" refers to a technology that enables the vehicle to automatically control and adjust its position within a lane. Automated lateral control typically includes steering the vehicle to keep it centered in the lane, as well as adjusting the lane position as needed, for example, when changing lanes or navigating curves. Such driver assistance systems use various sensors, such as radar, lidar, ultrasound, and / or cameras, to gather information about the vehicle's surroundings, particularly lane markings. Based on this data, the vehicle can then steer autonomously without driver intervention.

[0017] The first set of automated driving functions and the second set of automated driving functions differ at least partially with regard to a functional aspect of the automated driving functions and / or with regard to a type of automated driving function. 24-0985

[0018] The term “type of automated driving functions”, as used in this disclosure, refers to the different categories of systems used to automate various aspects or specific tasks of driving. Examples include, but are not limited to, lane keeping assist, lane change assist, overtaking assist, adaptive cruise control, emergency braking assist, automated parking, etc.

[0019] The term “functional characteristics of the automated driving functions,” as used in this disclosure, refers to the specific properties of the driving functions and the extent to which these driving functions provide assistance to the driver. The functional characteristics encompass both the technical features and the degree of automation of the respective driving function. In particular, the functional characteristics relate to control tasks, i.e., which specific control tasks the automated driving function performs, such as accelerating, braking, steering, and / or lane keeping.

[0020] Preferably, at least one similar driving function of the first set of automated driving functions and the second set of automated driving functions has a different functional configuration for automated driving. For example, an adaptive cruise control can use different maximum speeds, accelerations, decelerations, etc.

[0021] Preferably, the functional characteristics of the automated driving functions relate to their availability. The availability of the automated driving functions refers to the condition under which the automated driving functions are ready for use, usable, and / or permitted to be used.

[0022] Preferably, at least one similar driving function of the first set of automated driving functions and the second set of automated driving functions exhibits different availability under the same conditions. For example, a specific automated driving function, such as an automated 24-0985

[0023] Longitudinal guidance and / or automated lateral guidance may be available at a specific speed in the case of the first sentence, and may not be available at the same speed in the case of the second sentence. In particular, speed thresholds for the availability / usability of the driving function may differ (e.g., a maximum speed up to which the driving function can be used or a minimum speed from which the driving function can be used).

[0024] Preferably, the functional configuration of the automated driving functions relates to a vehicle speed during automated driving. For example, the functional configuration of the automated driving function can relate to a maximum vehicle speed for automated driving and / or an offset (e.g., adjustable by a user) for a vehicle speed above a speed limit.

[0025] Preferably, at least one similar driving function of the first set of automated driving functions and of the second set of automated driving functions has a different maximum vehicle speed for automated driving.

[0026] Preferably, the functional configuration of the automated driving functions relates to vehicle acceleration during automated driving. For example, the functional configuration of the automated driving function can relate to maximum vehicle acceleration for automated driving. This vehicle acceleration can be positive (accelerating) or negative (decelerating or braking).

[0027] Preferably, at least one similar driving function of the first set of automated driving functions and the second set of automated driving functions has a different maximum (negative and / or positive) vehicle acceleration for automated driving. 24-0985

[0028] Preferably, the functional configuration of the automated driving functions relates to at least one driving maneuver. This driving maneuver could, for example, be a lane change, but the present disclosure is not limited to this. For instance, a specific driving maneuver, such as a lane change on a road without lane markings, might be available in the case of the first sentence and might not be available in the case of the second sentence.

[0029] Preferably, the first set of automated driving functions complies with at least one first regulation, and the second set of automated driving functions complies with at least one second regulation. In this context, the term "regulation" refers to the established legal and normative requirements that automated driving functions must meet to be used safely, reliably, and legally in vehicles. This regulation is carried out by national and international authorities as well as by organizations such as the UNECE (United Nations Economic Commission for Europe), which develop specific regulations and standards for vehicle technologies.

[0030] Preferably, at least one functional embodiment of at least one automated driving function is compliant with the first regulation and not compliant with the at least one second regulation (or can be not compliant with the first regulation and compliant with the at least one second regulation). Additionally or alternatively, at least one type of automated driving function can be compliant with the first regulation and not compliant with the at least one second regulation (or can be not compliant with the first regulation and compliant with the at least one second regulation).

[0031] For example, the following driving functions may be eligible for approval under a first regulation (e.g. ECE-R13H / ECE-R79), but not under a second regulation (e.g. ECE-R171): automated driving up to very high speeds

[0032] Offset to the speed limit 24-0985

[0033] Furthermore, the following driving functions may be eligible for approval under the second regulation (e.g. ECE-R171), but not under the first regulation (e.g. ECE-R13H / ECE-R79):

[0034] Lateral guidance on roads without lane markings

[0035] Crossing lines, e.g., in an emergency lane

[0036] Lane changes even on roads without physical separation; higher lateral acceleration, e.g., in turning situations; SAE Level 2 hands-free driving.

[0037] Preferably, the vehicle, and in particular the driver assistance system, comprises a communication module configured to receive the first set of automated driving functions and / or the second set of automated driving functions from an external source (e.g., a server or backend). In some embodiments, the first set of automated driving functions may be a set originally present in the vehicle, and the second set may be subsequently installed or otherwise provided. For example, certain driving functions may be newly authorized and / or purchased by the user, so that a new set with these driving functions can be made available for use in the vehicle in addition to the set already present.

[0038] Additionally or alternatively, the communication module can be configured to receive configuration data for the first set of automated driving functions and / or the second set of automated driving functions from an external source (e.g., a server or backend). In some embodiments, both the first and second sets may already be present in the vehicle, although only the first set is usable. The configuration data can then be used to enable the second set. For example, certain driving functions can be purchased by the user, so that a new set containing these driving functions can be added to or configured in the vehicle for use, in addition to the existing set. 24-0985

[0039] Preferably, the driver assistance system further comprises a user interface module that is configured to receive user input for selecting the first set of automated driving functions or the second set of automated driving functions for automated driving.

[0040] The user interface module can comprise at least one output device (for displaying information related to the selection of the set of automated driving functions) and at least one input device (for selecting the set of automated driving functions). The user interface module can, for example, be a central information output and input device of an infotainment system, such as a head unit or a pillar-to-pillar display. Preferably, the user interface module is permanently installed in the vehicle.

[0041] Preferably, the user interface module comprises, or is, a touchscreen that provides at least one output device and at least one input device.

[0042] Preferably, the selection module is configured to automatically select either the first set of automated driving functions or the second set of automated driving functions based on at least one circumstance parameter.

[0043] Preferably, at least one circumstance parameter relates to a road type (e.g., city street, country road or motorway) and / or a vehicle position (e.g., urban or rural), but the present disclosure is not limited to this.

[0044] According to another independent aspect of the present disclosure, a vehicle, in particular a motor vehicle, is specified. The vehicle comprises the driver assistance system according to the embodiments of the present disclosure. 24-0985

[0045] The term "vehicle" includes cars, trucks, vans, buses, motorhomes, motorcycles, etc., used for the transport of people, goods, etc. In particular, the term includes motor vehicles for passenger transport.

[0046] The driver assistance system is configured for automated driving. For the purposes of this document, "automated driving" refers to driving with automated longitudinal and / or automated lateral control. Automated driving can, for example, involve extended periods of driving on the highway or time-limited driving during parking maneuvers. The term "automated driving" encompasses automated driving at any level of automation. Examples of automation levels include assisted, partially automated, conditionally automated, highly automated, and fully automated driving (each with an increasing degree of automation). The five automation levels mentioned above correspond to SAE Levels 1 to 5 of the SAE J3016 standard (SAE - Society of Automotive Engineering) as of April 30, 2021.

[0047] In assisted driving (SAE Level 1), the system performs longitudinal or lateral control in certain driving situations. In partially automated driving (SAE Level 2), the system takes over longitudinal and lateral control in certain driving situations, although the driver must continuously monitor the system, as with assisted driving. In conditionally automated driving (SAE Level 3), the system takes over longitudinal and lateral control in certain driving situations without the driver needing to continuously monitor the system; however, the driver must be able to take over vehicle control within a certain timeframe if requested by the system. In highly automated driving (SAE Level 4), the system takes over vehicle control in certain driving situations, even if the driver does not respond to a request to intervene, thus eliminating the driver as a fallback option.In fully automated driving (SAE Level 5), the system can perform all aspects of the dynamic driving task under any road and environmental conditions that a human driver can also perform. 24-0985.

[0048] Furthermore, the term "at least partially automated driving or maneuvering" within this document is understood to encompass partially automated, conditionally automated, highly automated, and fully automated driving. In other words, the term "at least partially automated driving" refers to a level of automation from SAE Level 2 onwards.

[0049] According to another independent aspect of the present disclosure, a driver assistance system for a vehicle, in particular a motor vehicle, is specified. The driver assistance system comprises:

[0050] Performing automated driving, through a driving module, using a first set of automated driving functions;

[0054] According to another independent aspect of the present disclosure, a software (SW) program is specified. The SW program can be configured to run on one or more processors and thereby execute the driver assistance procedure described in this document.

[0055] According to another independent aspect of the present disclosure, a storage medium is specified.

[0056] According to another independent aspect of the present disclosure, software with program code is specified. The software is configured to perform the driver assistance procedure described in this document when the software runs on one or more software-controlled devices.

[0057] According to another independent aspect of the present disclosure, a system is specified.

[0063] Figure 3 shows a flowchart of a driver assistance system according to embodiments of the present disclosure. 24-0985

[0064] Implementations of the revelation

[0065] Unless otherwise noted, the same reference symbols are used for identical and equivalent elements in the following.

[0066] Figure 1 schematically shows a vehicle 10 with a driver assistance system 100 for automated driving according to embodiments of the present disclosure.

[0067] In automated driving, the longitudinal and / or lateral control of the vehicle 10 is automatic. The driver assistance system 100 therefore takes over vehicle control. For this purpose, the driver assistance system 100 controls the drive 20, the steering 22, the optional transmission 24 and the (e.g. hydraulic) service brake 26 via intermediate units not shown.

[0068] For the planning and execution of automated driving, environmental information from sensors that monitor the vehicle's surroundings is received by the driver assistance system 100. In particular, the vehicle 10 can include at least one environmental sensor 12, which is configured to record environmental data specifying the vehicle's surroundings. The at least one environmental sensor 12 can, for example, include one or more LiDAR systems, one or more radar systems, one or more ultrasonic sensors, and / or one or more cameras.

[0069] Figure 2 schematically shows a driver assistance system 200 according to embodiments of the present disclosure.

[0070] The driver assistance system 200 may include or be the driver assistance system 100, which is described with reference to Figure 1.

[0071] The driver assistance system 200 comprises a driving module 210 configured for automated driving, wherein the driving module 210 is configured to provide a first set S1 of automated driving functions and a second set S2 of automated 24-0985

[0072] to implement driving functions, wherein the first set S1 of automated driving functions and the second set S2 of automated driving functions differ at least partially with regard to a functional aspect of the automated driving functions and / or with regard to a type of automated driving functions.

[0073] The driver assistance system 200 further includes a selection module 220, which is configured to select either the first set S1 of automated driving functions or the second set S2 of automated driving functions for automated driving based on user input and / or based on at least one circumstance parameter.

[0074] In some embodiments, the automated driving functions of the first set S1 of automated driving functions and / or the automated driving functions of the second set S2 of automated driving functions include, or relate to, automated longitudinal control and / or automated lateral control of the vehicle 10.

[0075] The first set S1 of automated driving functions and the second set S2 of automated driving functions may differ, at least partially, with respect to the type of automated driving function. Examples of types of automated driving functions include, but are not limited to, lane keeping assist, lane change assist, overtaking assist, adaptive cruise control, emergency braking assist, automated parking, etc.

[0076] Additionally or alternatively, the first set S1 of automated driving functions and the second set S2 of automated driving functions may differ, at least partially, with regard to a functional characteristic of the automated driving functions. This functional characteristic relates, for example, to control tasks, i.e., which specific control tasks the automated driving function performs and in what form, such as accelerating, braking, steering, and / or lane keeping. 24-0985

[0077] In some embodiments, at least one similar driving function of the first set S1 of automated driving functions and of the second set S2 of automated driving functions has a different functional configuration for automated driving. For example, an adaptive cruise control can use different maximum speeds, accelerations, decelerations, etc.

[0078] In some embodiments, the functional characteristics of the automated driving functions relate to their availability. For example, a specific automated driving function, such as automated longitudinal control and / or automated lateral control, may be available at a certain speed in the first case, but may not be available at the same speed in the second case. In particular, speed thresholds for the availability / usability of the driving function may differ (e.g., a maximum speed up to which the driving function can be used or a minimum speed from which the driving function can be used).

[0079] In some embodiments, the functional configuration of the automated driving functions relates to a vehicle speed during automated driving. For example, the functional configuration of the automated driving function can relate to a maximum vehicle speed for automated driving and / or an offset (e.g., adjustable by a user) for a vehicle speed above a speed limit.

[0080] In some embodiments, the functional configuration of the automated driving functions relates to vehicle acceleration during automated driving. For example, the functional configuration of the automated driving function may relate to maximum vehicle acceleration for automated driving. This vehicle acceleration can be positive (accelerating) or negative (decelerating or braking). 24-0985

[0081] In some embodiments, the functional configuration of the automated driving functions relates to at least one driving maneuver. This driving maneuver could, for example, be a lane change. For instance, a specific driving maneuver, such as a lane change on a road without lane markings, might be available in the case of the first sentence S1, and might not be available in the case of the second sentence S2.

[0082] In some embodiments, the first set S1 of automated driving functions corresponds to at least one first regulation, and the second set S2 of automated driving functions corresponds to at least one second regulation. For example, at least one functional instance of at least one automated driving function is compliant with the first regulation and not compliant with the at least one second regulation (or may be not compliant with the first regulation and compliant with the at least one second regulation). Additionally or alternatively, at least one type of automated driving function may be compliant with the first regulation and not compliant with the at least one second regulation (or may be not compliant with the first regulation and compliant with the at least one second regulation).

[0083] For example, the following driving functions may be eligible for approval under a first regulation (e.g. ECE-R13H / ECE-R79), but not under a second regulation (e.g. ECE-R171): automated driving up to very high speeds

[0084] Offset to the speed limit

[0085] Furthermore, the following driving functions may be eligible for approval under the second regulation (e.g. ECE-R171), but not under the first regulation (e.g. ECE-R13H / ECE-R79):

[0086] Lateral guidance on roads without lane markings

[0087] Crossing lines, e.g., in an emergency lane

[0088] Lane changes even on roads without physical separation; higher lateral acceleration, e.g., in turning situations; SAE Level 2 hands-free driving (24-0985)

[0089] In some embodiments, the vehicle, in particular the driver assistance system 200, includes a communication module 230 configured to receive the first set S1 of automated driving functions and / or the second set S2 of automated driving functions from an external source (e.g., a server or backend). In some embodiments, the first set S1 of automated driving functions may be a set originally present in the vehicle, and the second set S2 may be subsequently installed or otherwise provided. For example, certain driving functions may be newly authorized and / or purchased by the user, so that a new set with these driving functions can be made available for use in the vehicle in addition to the set already present.

[0090] Additionally or alternatively, the communication module 230 can be configured to receive configuration data for the first set S1 of automated driving functions and / or the second set S2 of automated driving functions from an external source (e.g., a server or backend). In some embodiments, both the first set S1 and the second set S2 may already be present in the vehicle, although only the first set S1 is usable. The configuration data then enables the second set S2 to be used as well. For example, certain driving functions can be purchased by the user, so that a new set containing these driving functions can be added to or configured for use in the vehicle, in addition to the existing set.

[0091] In some embodiments, the driver assistance system 200 further includes a user interface module that is set up to receive user input for selecting the first set S1 of automated driving functions or the second set S2 of automated driving functions for automated driving.

[0092] In other embodiments, the selection module 220 can be configured to automatically select either the first set S1 of automated driving functions or the second set S2 of automated driving functions based on at least one circumstance parameter. The at least one circumstance parameter can, for example, relate to a road type (e.g., urban road, rural road, or highway) and / or a vehicle position (e.g., urban or rural), but the present disclosure is not limited to this.

[0093] Figure 3 schematically shows a flowchart of a driver assistance system 300 for a vehicle according to embodiments of the present disclosure. The driver assistance system 300 can be implemented by corresponding software that can be executed by one or more processors (e.g., a CPU).

[0094] The driver assistance procedure 300 comprises, in block 310, the execution, by a driving module, of automated driving using a first set of automated driving functions; in block 320, the selection, by a selection module, of a second set of automated driving functions for automated driving based on user input and / or based on at least one circumstance parameter, wherein the first set of automated driving functions and the second set of automated driving functions differ at least partially with respect to a functional aspect of the automated driving functions and / or with respect to a type of automated driving functions; and in block 330, the execution, by the driving module, of automated driving using the second set of automated driving functions.

[0095] According to the invention, an entire package of driving functions is replaced or reconfigured by adding new functions, rather than adding or removing individual functions. For example, an "old" package of driving functions can be replaced by a "new" package, where the old and new packages comply with different regulations (e.g., ECE-R171, ECE-R13H, ECE-R79, etc.). Unlike adding or removing individual driving functions, this changes the vehicle's fundamental behavior, for example, with regard to speed limits and specific driving behavior, such as during lane changes. Depending on the situation, either the "old" package (e.g., the classic package) or the "new" package (e.g., a newly approved or purchased package) can now be used for automated driving. The result is optimal use of automated driving functions.

[0096] Although the invention has been further illustrated and explained in detail by means of preferred embodiments, the invention is not limited by the disclosed examples, and other variations can be derived from them by a person skilled in the art without departing from the scope of protection of the invention. It is therefore clear that a multitude of possible variations exist. It is also clear that the embodiments mentioned as examples are truly only examples and are not to be understood in any way as limiting, for example, the scope of protection, the possible applications, or the configuration of the invention.Rather, the preceding description and the description of the figures enable the person skilled in the art to implement the exemplary embodiments in concrete terms, whereby the person skilled in the art, with knowledge of the disclosed invention concept, can make various changes, for example with regard to the function or the arrangement of individual elements mentioned in an exemplary embodiment, without leaving the scope of protection defined by the claims and their legal equivalents, such as further explanations in the description.
