Description

The invention relates to a method, a system and a corresponding computer program for operating a vehicle that can be driven at least partially in an automated and / or remote-controlled manner.

Various vehicle systems, for example those that include power steering, brake boosters, etc., are operated in motor vehicles in a very wide range with very different operating conditions and in combinations of such conditions. This brings with it considerable challenges to design and manufacture safety-relevant components of the vehicle for a very long operating period and various combinations of operating conditions and to monitor and maintain them during the service life of the vehicle. In the event of unavailability, failure, malfunction or poor performance of such systems, the driver of the vehicle is usually responsible, e.g. with his driving skills, to avert possible undesirable consequences. With the market launch of vehicles that are automated, remote-controlled or driverless to a high degree, these challenges can become more acute. A critical change to the vehicle in the course of its life cycle (even with frequent maintenance intervals) can also go unnoticed.

The object of this invention is to provide an improved method, system and a corresponding computer program for operating an at least partially automated, remote-controlled and / or driverless vehicle. In particular, it is the object of the invention to increase the operational readiness and / or performance of an at least partially automated and / or remote-controlled operation of a vehicle. Furthermore, it is the object of the invention to provide an improved automated and / or at least partially remote-controlled functionality of the vehicle.

These objects are achieved by the features of the independent patent claim. Advantageous embodiments are characterized in the dependent claims. It is pointed out that additional features of a patent claim dependent on an independent patent claim without the features of the independent patent claim or only in combination with a subset of the features of the independent patent claim can form a separate invention independent of the combination of all features of the independent patent claim, which can be made the subject of an independent claim, a divisional application or a subsequent application. This applies equally to technical teachings described in the description, which can form an invention that is independent of the features of the independent patent claims.

The following statements on the method according to the invention also apply in a corresponding manner to the system according to the invention and the corresponding computer program. Further features and advantages of the invention emerge from the following description of exemplary embodiments of the invention, with reference to the figure which shows details according to the invention, and from the claims. The individual features can each be implemented individually or collectively in any combination in a variant of the invention.

According to a first aspect of the invention, a method for operating an at least partially automated and / or remotely controlled vehicle is provided, the method comprising: determining a degree of automation and / or a degree of remote control with which the vehicle is in a current and / or subsequent time interval is operated, and then initiating at least one test procedure with respect to a system of the vehicle. The initiation of the at least one test procedure, e.g. the point in time and / or a parameter of the test procedure can be determined (e.g. selected, adapted) depending on the determined degree of automation and / or a degree of remote control. One or more results of the test procedures can then be provided to the vehicle (e.g. to a system of the vehicle) and / or to one or more other vehicles. The vehicle or the one or more further vehicles can be operated depending on the provided results of the one or more test procedures. The one or more further (second) vehicles differ in particular from the (first) vehicle.

The test procedure in relation to a system of the vehicle can be initiated and carried out within the vehicle. This can be initiated by a device of the vehicle provided for this purpose, in particular that deviates from the system of the vehicle (in relation to the system of the vehicle). Alternatively, the test procedure can be initiated from outside the vehicle, for example from a computing unit located outside the vehicle. The test procedure can be carried out with regard to the operational readiness, failure probability and / or performance of the (specific) system of the vehicle become. The system of the vehicle can include an actuator of the vehicle. The result of the test procedure can directly or indirectly identify the current or expected operational readiness, failure probability and / or performance of the vehicle system. Furthermore, the test procedure can relate to two or more systems of the vehicle, which are at least potentially activated during an automated and / or remote-controlled operation of the vehicle that is currently being carried out or is imminent.

The provision of a result of the test procedure (this also means data characterizing the result of the test procedure) for the vehicle (the same vehicle in which the test procedure was carried out) can be done by means of storage (at least partially in the vehicle and / or at least partially outside of the vehicle) and a later reading out (and consideration) of the result of the test procedure. For example, the result of the test procedure can be stored together with further information identifying position information, an operating parameter, a driving situation of the vehicle, and / or data identifying the surroundings of the vehicle. The result of the test procedure (this means that further processed data on the basis of the test procedure can also be understood) can then, in particular depending on further information (applicable at the given time interval), e.g. characterizing position information, an operating parameter, a driving situation of the vehicle, and / or data characterizing the surroundings of the vehicle can be read out and taken into account in the operation of the vehicle. The result of the test procedure can preferably be assigned to a digital map (e.g. to one or more corresponding position information items) and provided from the map.

In particular, the method comprises the operation of the vehicle and / or the one or more further vehicles depending on the one or more provided results of the test procedure or test procedures. For example, several test procedures, in particular with two or more different degrees of automation and / or degrees of remote control, are initiated in the vehicle and made available to the one or more further vehicles. An automated and / or remote-controlled operation of the one or more other vehicles can then be carried out, e.g. at least to a certain extent permitted and / or restricted.

In particular, the said degree of automation or the degree of remote control relates to driving (read: performing or supporting a driving task). Alternatively or additionally, the degree of automation or the degree of remote control can relate to a functionality of the vehicle that does not relate to driving or functionalities that are largely independent of a driving task. For example, the degree of automation or the degree of remote control can relate to a functionality that can (also) be executed when the (stationary, parked, parked) vehicle is at a standstill, e.g. at least partially automated and / or at least partially remote-controlled. For example, it can be a functionality comprising a light function, actuation of a flap, roof, window, convertible top of the vehicle. At least partially remote-controlled driving can in turn be or include at least temporarily remote-controlled driving. The control of the movement of the vehicle (even if a driver who is ready to take action or who is not ready to take action is in the vehicle) can be remotely controlled at least temporarily, e.g. for a certain period of time, so to speak "on demand".

In the context of this description, the variable representing the degree of automation can be a current degree of automation or a degree of automation determined for the near future (1-30 seconds) or a corresponding variable.

For example, the variable representing the degree of automation can be assumed to be high if the degree of automation increases and has exceeded a certain level and / or can be assumed to be low if the level of automation falls and has fallen below a predetermined level. A measure of the degree of automation accumulated over time can particularly preferably be taken into account.

The degree of automation can be defined as dimensions or category values according to VDA (Association of the Automotive Industry) or BASt, for example. For example, these can be classes or category values for manage levels. In addition, the invention includes that the degree of automation or degree of remote control is (also) applied individually, selectively or in certain combinations to certain (selected) aspects of an automation or remote control. For example, a degree of automation (a variable representing the degree of automation or the degree of remote control) can also be selective in relation to at least two different aspects of the automation of the movement of the vehicle and / or for two or more different driver assistance functions of the vehicle in the control unit, e.g. Reference to a: longitudinal guidance of the vehicle and / or lateral guidance of the Vehicle and / or implementation of a lane change and / or implementation of an overtaking maneuver and / or driver information, in particular in connection with driving the vehicle and / or performing certain driving maneuvers (e.g. lane change, overtaking maneuver, turning maneuver, cutting-in maneuver, evasive maneuver) or a specific parking or maneuvering maneuver.

Particularly preferably, one or more of the features, parameters or steps of the method discussed in this document are varied, depending on whether the vehicle is at least partially automated, at least partially remote-controlled, and / or at least temporarily operated without a driver, or whether an intention is recognized for the vehicle at least partially automated, at least partially remote-controlled, and / or at least temporarily to move without a driver. For example, the method is only carried out in a certain variant, at least predominantly only, if an automated and / or remote-controlled one is operated in the vehicle without occupants or without a driver, e.g. only with passengers (who are not drivers).

The at least one test procedure can be a test procedure with regard to (or pertaining to) operational readiness, a failure probability and / or the performance of a system or of the actuator of the vehicle. The at least one test procedure can include an actuation (at least as a test) of at least one actuator of the vehicle. This actuation can in turn be related to an automated and / or at least partially remote-controlled functionality of the vehicle, e.g. to move the vehicle.

For example, the result of the test procedure can relate to a system or actuator of the vehicle that will be required or will be actuated for the execution of an automated or remote-controlled drive of the vehicle. The test procedure can, for example, also relate to a system or an actuator of the vehicle that can be required or used (only or at least) with a certain probability or only in a specific, possibly rarely occurring, case, for example in In the event of a so-called fail safe, a risk avoidance maneuver, and / or alternative scenarios in the event of an automated or remote-controlled operation of the vehicle.

Alternatively or additionally, the result of the test procedure can be indicative of how or how successfully a transition to a certain degree of automation and / or degree of remote control of the vehicle has been made. For example, depending on the result of the test procedure, it can be decided whether and / or with what level and / or in what degree of automation or remote control the operation of the one or more further vehicles, in particular at the same (or in the vicinity) position, at an otherwise similar operating parameter in a similar driving situation and / or data characterize the surroundings of the vehicle. For example, depending on the one or more results of the test procedure, it can be determined which values the degree of automation or the degree of remote control of the one or more further vehicles may or should assume.

The one or more results of the test procedures can be handled in the method (as corresponding data or identifiers) as card information. For example, the digital map (e.g. a so-called map layer provided for this purpose) is described with the data characterizing the results of the test procedures in relation to one or more systems of the vehicle. The vehicle and / or one or more (also: multitude) other vehicles can read out the corresponding data from the map on the basis of the results of the test procedures, e.g. before or during driving on the corresponding lane sections.

The term “then” can be understood as initiating a test procedure immediately or within a certain period of time, in particular in the same clamping cycle of the vehicle. For example, a test procedure can be initiated, in particular a point in time for initiating the test procedure can be selected, in a predetermined dependence on the prediction of an at least probable need for an automated and / or at least partially remote-controlled actuation of a system or an actuator of the vehicle, in particular depending on one Probability value, time value or a value characterizing an intensity of the at least one predicted activity. The result of the at least one test procedure can (also) only be taken into account in a later terminal cycle when the vehicle is later driven.

The initiation of at least one test procedure can include a selection of at least one of a plurality of test procedures. For example, depending on an identifier, the prediction of an at least probable need for an automated and / or at least partially remote-controlled actuation of an actuator of the vehicle, for example depending on a probability value, time value or a Value characterizing an intensity of the predicted actuation, one of several (possibly differently complex or differently safe) test procedures can be selected and initiated.

The initiation, in particular the selection of the test procedure, can take place depending on whether the actuator is at least likely to be a manual action, e.g. the driver actuates a pedal, steering wheel or control element of the vehicle, or at least predominantly automated and / or at least partially remote-controlled will be operated. For example, if only a need for manual actuation of the actuator is recognized, no test procedure or a (reduced) test procedure provided for this is carried out.

If a probable need for an automated and / or at least partially remote-controlled actuation of an actuator of the vehicle in connection with an automated and / or at least partially remote-controlled functionality of the vehicle is recognized, one or more test procedures (specific, appropriately dimensioned) are selected and initiated.

It should be expressly mentioned that the method, the system and the computer product are not limited to the term “test” in a technical sense. The terms “test” or “test procedure” were used in the context of this document (also in the absence of special technical terms). These terms can in particular represent a sequence described in this document for determining information on the operation and / or the state of at least part of a vehicle, in particular characterizing operational readiness, failure probability and / or performance of an actuator of the vehicle.

It should be expressly mentioned that automated and / or at least partial actuation of the actuator in the context of this document does not necessarily have to relate to an actuator for moving the vehicle (or not necessarily a movement of the vehicle as a whole). The at least partially remote-controlled actuation of the actuator means in particular that at least one signal, e.g. a signal that is dependent on an operator action by a user outside the vehicle, is taken into account when controlling the actuator. In the method, one or more different identifiers for the operational readiness, failure probability and / or performance of the actuator can be determined. These can include one or more (possibly mutually orthogonal) quantitative measures. These can identify information about an expected operation of the actuator.

Said test procedure can include an (active) influencing of at least a part of the vehicle or a variable within the vehicle (e.g. in turn relating to a component of the system of the vehicle). For example, the at least one test procedure can include that a specific action is initiated on a component of the vehicle (actively as part of the test procedure or in order to determine a result of the test procedure). Furthermore, the test procedure can include determining an indicator, characterizing an effect of one or more influences on the vehicle from outside the vehicle and / or the said (initiated) effect. Furthermore, the test procedure can include determining a result of the test procedure. A determined indicator can be compared with a predetermined condition.

For example, the at least one test procedure can include a rule for executing a specific influence on at least part of the vehicle and / or a rule for determining the result of the test procedure. The result of the at least one test procedure can be determined as a function of a change in the vehicle that was recognized when the test procedure was initiated, e.g. a comparison of a determined change in the vehicle with a predetermined condition. The test procedure or a rule, e.g. adapted to an application, for executing the test procedure can be stored or generated in a device of the vehicle or in a mobile user device (e.g. in a user device of the user of the vehicle). A feature of the test procedure, e.g. a result of the test procedure, can be verified or verifiably processed by means of a so-called blockchain technology known per se to the person skilled in the art. A (verifiable) association between a parameter of the test procedure, an identifier of the situation in which the test procedure was carried out, information identifying the vehicle and an operating parameter of the vehicle can be determined, stored and, if necessary, used in the method.

The term “remote-controlled operation” is to be understood in the context of the present document in particular that at least one functionality of the vehicle, in particular the movement (travel) of the vehicle, at least partially or also temporarily from outside the vehicle, for example at a distance of a few meters or from a greater distance, with or without visual contact with the vehicle, is influenced, initiated and / or controlled. The movement can preferably be controlled at least partially by the user (for example depending on at least one operating action by the user) and / or by a computing unit located outside the vehicle. For example, the at least partially automated and / or at least partially remote-controlled operation of the vehicle can be associated with parking, unparking and / or maneuvering the vehicle, e.g. a parameter of a parking, unparking or maneuvering is carried out in an automated and / or remote-controlled manner.

The automated and / or remote-controlled operation of the vehicle can in particular be (at least partially or temporarily) driverless operation. This is to be understood in such a way that in the case of an at least partially automated and / or remote-controlled execution of the functionality of the vehicle, at least temporarily no presence of the driver in the interior of the vehicle, or a presence that is limited to a certain extent, is required. For example, to carry out an automated and / or remote-controlled operation, in particular to carry out a movement of the vehicle, the driver does not need to be present in the interior of the vehicle and / or in the vicinity of the vehicle.

In particular, it can be an operation of the vehicle in which the user of the vehicle, in particular the driver, at least temporarily, e.g. during the execution of a certain part of a movement of the vehicle, or for a certain time interval, in connection with the actuation of the actuator of the The vehicle is not active (e.g. not ready to drive or asleep), is not present in the interior of the vehicle, is outside a certain distance from the vehicle and / or has no visual contact with the vehicle. The vehicle can also be at least partially remote-controlled, in particular by a further user. For example, the vehicle or another vehicle can be operated depending on the information provided for automated and / or remote-controlled parking, maneuvering out of parking spaces or maneuvering, in which the user is outside the vehicle in the vicinity of the vehicle and the vehicle is moving with a mobile user device , e.g. smartphone, Smart-Close, or controls with the vehicle key.

In a further example that can be combined with all further features and examples, the user, in particular the “driver” of the vehicle, is a technical device located at a distance from the vehicle. In other words, the user can be a not human, but a technically realized “user”. Such a user or “driver” can in particular be a being, dispatcher or client based on an artificial intelligence, for example. In this example, the user, in particular the “driver”, can also be software (from the mobile user device and / or from the backend) or a “person” implemented as software who uses the at least partially remote-controlled driving functionality of the vehicle. In particular, one or more movement parameters of the vehicle can be controlled, in particular regulated, at least partially (to a certain extent) from a distance by the software.

In this example, the remote-controlled movement of the vehicle can be a movement of the vehicle initiated from a distance by a human user, for example with regard to a feature of the movement. For example, the movement of the vehicle can be a movement by a human user, in particular a parameter of the movement trajectory and / or a maneuver pattern specified by the driver (at least in an abstract form). For example, (only) a comparatively abstract specification for a movement of the vehicle to be carried out or aimed at by a human user can be required or taken into account, e.g. a selection of one or more symbols on the mobile user device made by a user. One or more of the corresponding movement parameters can thereupon (again by a virtual “user” or “driver”) be executed at least partially remotely.

Preferably, the determination of the degree of automation or the degree of remote control is or comprises a prediction of a degree of automation or the degree of remote control or an increase in a degree of automation and / or a degree of remote control. Such a prediction can relate to a specific route section and / or a time interval and / or one or more changes, tendencies, an at least partial change between remote-controlled operation and / or automated operation of at least one functionality of the vehicle, in particular driving or parking , and the like. For example, the determined (predicted) degree of automation and / or degree of remote control can identify one or more of the degrees of automation or degrees of remote control (as certain dimensions, gradations, identifiers) for certain future route sections and / or time intervals. For example, a (certain) transition from an automated Trip to a remote-controlled trip or vice versa, in particular from a certain degree of automation to a certain level of remote control, are predicted. Such predicted information on the degree of automation and / or the degree of remote control can (at least primarily) be taken into account if it exceeds a certain degree of probability of occurrence.

A prediction of the degree of automation and / or degree of remote control can be determined as a function of map data, e.g. a section or a so-called layer of a digital map of the surroundings of the vehicle, in particular by means of a suitable algorithm and / or by means of artificial intelligence (active). The result of the prediction can include information which is indicative of how the desired or required degree of automation and / or degree of remote control will be at a time interval in the near future or how this will change. It can also be determined and taken into account which system and / or which actuator of the vehicle is operated and / or ready for operation within a (comparatively short) time interval (at least with a certain probability) within the framework of the (respective) automated or remote-controlled operation, in particular must be within a certain range of values with regard to the probability of failure, availability and / or performance.

Furthermore, the prediction can identify an identifier for the probability of an actuation, an operating parameter of an actuation and / or a time interval of an actuation (or the specific actuation). For example, the test procedure can be selected, parameterized or adapted, depending on which system or which actuator of the vehicle, with which probability and / or with which operating parameters (e.g. in the context of a current or upcoming automated and / or remote-controlled operation) are operated is or should be ready for operation.

Preferably, the prediction of an at least probable need for actuation of an actuator of the vehicle can be made depending on one or more signals and / or events that are associated with, in particular subsequent, actuation of the at least one (specific) actuator in a causal, temporal or correlative context stand. For example, an at least probable need to actuate an actuator of the vehicle can be determined as a function of a statistical relationship from the history, e.g. with regard to one or more frequencies of occurrence, in connection with one or more signals or events. An event can, for example, identify the surroundings of the vehicle, e.g. an interaction or a probable or threatening interaction with another road user. For example, a test procedure, in particular a specific test procedure provided or adapted to it, can be initiated if it is determined that the vehicle is overtaken by another road user, pushed by a road user or requested or requested by a road user to perform an action, a maneuver, etc. . is required.

In particular, a certain combination or a certain pattern of at least two signals or events is recognized and it is then concluded that there is likely to be a need to actuate an actuator of the vehicle, in particular at least with a certain degree of probability.

Merely by way of example, it is stated here that a certain combination of actuation of a (signal) light of the vehicle, a door or flap, e.g. a door contact of the vehicle, a certain operating pattern, maneuver and / or position information of the vehicle is triggered anticipated need for an (imminent) actuation of a specific actuator of the vehicle can be closed. In other words, the at least one test procedure can be initiated with regard to the operational readiness, failure probability and / or performance of the actuator of the vehicle if it is recognized that one or more signals, events or patterns of the signals or events are determined or recognized which occur at least particularly frequently with an actuation of a specific actuator (the actuator) in the vehicle or in (the) other vehicles. In this sense, in one example of the method, the prediction of an at least probable need to actuate an actuator of the vehicle in connection with an automated and / or at least partially remote-controlled movement of the vehicle can be equated with the determination of one or more signals and / or events, which have a causal, temporal or correlative connection with an, in particular subsequent, actuation of the actuator.

Depending on the determined, in particular predicted, degree of automation and / or a degree of remote control, in particular a specific increase in a degree of automation and / or a degree of remote control with which the vehicle is operated in a current or subsequent time interval a (suitable, expedient) test procedure, which requires a certain amount of time and / or resources, e.g. lasts several seconds and can possibly be time-consuming, can be carried out (as far as possible) in good time, ie before the start of the actual actuation and be evaluated. Thus, a test procedure does not have to be carried out unnecessarily or too often or to the detriment of energy consumption, functionality or disruptive for the user. A currently (in the current situation) valid (and thus more precise) result of the test procedure can also be determined and taken into account.

Then, e.g. on the evaluation of the result of the at least one test procedure in the vehicle, a transition from a current degree of automation or remote control to a higher degree of automation or remote control of the vehicle or one or more other vehicles can be initiated, enabled (not prevented or restricted ) or at least partially prevented.

For example, given a comparatively positive result of the test procedure, an increase in the degree of automation and / or the degree of remote control can be initiated or enabled (not prevented or restricted). In the event of a comparatively negative result of the test procedure (recognized or classified as negative), an increase in the degree of automation and / or the degree of remote control can at least partially be prevented and / or a condition for executing the increased degree of automation can be checked and (only) if the condition is met ( for example with regard to a readiness to drive the user of the vehicle) an increase in the degree of automation or the degree of remote control can be carried out.

In the method, a prediction can also be made and taken into account that there is no need, or with a high probability, no need to actuate an actuator of the vehicle, e.g. in connection with a functionality, in particular in the case of an automated and / or at least partially remote-controlled movement of the vehicle becomes. Thereupon, for example, either no test procedure or a significantly reduced test procedure can be carried out. For example, in certain applications and / or for certain functionalities of the vehicle, a decision can be made that no test procedure or that this only has to be carried out in rare cases, e.g. in rare time intervals or after a few usage cycles.

The prediction of an at least probable need for actuation of a specific actuator of the vehicle can refer to a direct or indirect activation of a relevant functionality, e.g. a function that is dependent on the actuator. For example, the prediction that an automated and / or at least partially remote-controlled movement of the vehicle will soon be carried out (e.g. automatically) if it is recognized that this is not being prevented by the user or for some other reason.

In general, one or more specific actuators, e.g. drive, braking system, steering, a vertical dynamic actuator, etc., can also be determined, which are actuated with (each) a specific probability and / or with a specific operating parameter or within a specific operating parameter range.

In one example, it can first be predicted with a certain probability measure that a functionality, including at least partially remote-controlled parking or maneuvering for parking in a parallel parking space, perpendicular parking space, inclined parking space or for a corresponding parking space, will be used. Such a prediction can, for example, determine depending on the actuation of the door contacts, seat occupancy sensors, the position of the vehicle, a corresponding signal from a user device (e.g. smartphone) of the user, the detection of position information on which parking is frequent, and / or comparable criteria. Furthermore, a need to actuate an actuator of the vehicle in connection with a specific functionality can be determined. Particularly preferably, a parameter can be predicted, e.g. as an order of magnitude of an operating parameter, with which an actuation (in each case with a certain degree of probability) will take place.

A test procedure tailored to one or more upcoming pieces of determined information can then be planned, initiated and carried out. The at least one test procedure, in particular one or more parameters of the at least one test procedure, can be determined or adapted depending on the degree of automation, degree of remote control and / or other information described in this document according to a predetermined mathematical relationship. In a further embodiment, depending on the result of the at least one test procedure in the vehicle, one or more Test procedures, in particular certain test procedures, are initiated, preferably planned, in the one or more further vehicles. For example, if a result of the at least one test procedure in the vehicle has delivered a result that is comparatively poor or marginal according to predetermined criteria), several or more precise, more frequent test procedures are initiated in the one or more further vehicles.

In a simplified case, the test procedure can be an evaluation of the data relating to a first operating parameter of the actuator and / or a first operating parameter of the vehicle, e.g. finding certain patterns in the data of the vehicle and / or a comparison with other, for example, statistically determined data and / or so-called error memory data or information memory data.

The at least one test procedure can be a test procedure that is not necessary and / or expediently executable in the form of manual operation of the vehicle or not for operating the vehicle with a driver in the driver's seat, ie automated and / or or at least partially remotely executable.

In particular, the test procedure comprises a sequence or sequence of specific processes.

The at least one test procedure preferably comprises one or more physical processes, e.g. a movement of at least part of the vehicle, a chemical process, and / or one or more data processing processes. In particular, the test procedure comprises one or more processes which, per se or in the form in which they are provided in the test procedure, have no direct essential functional effect on the user.

Depending on the execution of a test procedure, a certain influencing of the at least one functionality can take place, in particular in a forward-looking manner, which at least probably requires an automated and / or at least partially remote-controlled movement of the vehicle or will require it with a certain probability.

In a further example that can be combined with all the features of the method, a signal dependent on the result of the test procedure can be sent to a user device (corresponding or belonging to the user of the vehicle), e.g. a smartphone, a smart watch and / or a vehicle key of the user, be sent. The mobile user device can be the same mobile user device by means of which an automated, driverless and / or at least partially remote-controlled movement of the vehicle is monitored and / or controlled.

The test procedure can be carried out in relation to part of the braking system, steering system, battery, (drive) motor and / or drive system (eg also a transmission, etc.) of a vertical dynamics system of the vehicle. The at least one test procedure can, for example, be carried out during (essentially or largely) manual driving of the vehicle, for example before an increase in the degree of automation and / or the degree of remote control. In particular, the at least one test procedure comprises a change in the operating parameters of such a system, in particular an actuation of an actuator and then a recording of the data characterizing a reaction that occurs to the change in the operating parameter. For example, a test procedure can include (very slight) actuation of the steering system of the vehicle, slight tilting, rolling, lifting or lowering of the vehicle.
For example, a test procedure can include an, in particular non-functional, comparatively weak or imperceptible or non-disruptive actuation of the system for the user of the vehicle. This can only or mainly be carried out to generate the result of the test procedure (eg not to change the movement of the vehicle).

Then, depending on the result of the test procedure, an at least partially automated and / or at least partially remote-controlled or remotely controllable functionality for controlling a lateral guidance parameter of the vehicle or one or more other vehicles can be operated. For example, an at least partially automated and / or at least partially remote-controlled or remotely controllable functionality of the vehicle can relate to steering the vehicle at the front wheels and / or rear wheels and / or a longitudinal guidance parameter, e.g. acceleration, deceleration, etc. Furthermore, a control of a vertical dynamic parameter of the vehicle, for example tilting, rolling, lifting or lowering of the vehicle, can be carried out as a function of the result of the test procedure. The remote control of the movement can also be understood, for example, as a change or correction of a movement of the vehicle caused from a certain distance. For example, said functionality can be in this way be pronounced that depending on an operating action by the user on the user device, a change, in particular a correction of a movement of the vehicle, for example at least automated and / or initiated by a vehicle occupant, is controlled (remotely).

Depending on the execution of the at least one test procedure, a measure of an at least probable operational readiness, failure probability and / or performance of the actuator of the vehicle can be determined and taken into account. Such a measure for the operational readiness, failure probability and / or a performance of the actuator of the vehicle can, for example, relate to an actuation of the actuator immediately or within a short time interval after the test procedure, in particular correspond to an expected value. One or more identifiers for the respective categories of dimensions, e.g. 2 - 8 gradations (instead of absolute values) can be determined and taken into account.

For example, depending on the result of the test procedure, a measure of the current operational readiness, failure probability and / or a performance of the actuator of the vehicle and / or preferably a measure of the operational readiness, failure probability and / or performance of the actuator of the vehicle related to a subsequent time interval, in particular an expected measure be determined. The expected operational readiness, failure probability and / or performance of the actuator of the vehicle can in turn be determined, estimated or extrapolated from an operational readiness, failure probability and / or performance of the actuator of the vehicle (applicable to the time interval of the execution of the test procedure). The actuator of the vehicle can also include one or more devices set up to operate the actuator, e.g. a corresponding power supply, connection to the data system of the vehicle, control unit, etc.

• - eine zumindest potentiell abrufbare Leistung des Aktors, beispielsweise eine mit dem Aktor ausführbare Bewegung, eine Amplitude, Kraft, Moment, oder mechanische Energie, oder
• - eine mit dem Aktor wandelbare Energie und/oder Energieeffizienz, oder
• - eine Belastbarkeit des Aktors, z.B. auch in Bezug auf ein mechanisches Entgegenwirken, oder
• - eine Präzision des Aktors, insbesondere eine Abweichung von einer Kennlinie, oder
• - eine Antwortzeit, Totzeit, Folgezeit und/oder ein Aufstartverhalten.

Beispielsweise kann die voraussichtliche, zu erwartende Performance in Form der jeweils zu erwartenden Maße ausgedrückt werden. Beispielsweise kann eine Performance ermittelt werden, die gekennzeichnet ist durch einen oder mehrere Mindestmaße (etwa als quantitative Werte) oder durch die Erreichbarkeit eines oder mehrerer vorausbestimmter Mindestmaße (etwa als digitale Werte).The said (e.g. current and / or expected) performance of an actuator (of the vehicle's system) can display an identifier, preferably a measure of one or more entries from the following list:

• an at least potentially retrievable power of the actuator, for example a movement that can be carried out with the actuator, an amplitude, force, moment, or mechanical energy, or
• - an energy and / or energy efficiency convertible with the actuator, or
• - a load capacity of the actuator, for example also in relation to a mechanical counteraction, or
• a precision of the actuator, in particular a deviation from a characteristic curve, or
• - a response time, dead time, follow-up time and / or a start-up behavior.

For example, the expected, expected performance can be expressed in the form of the respective expected dimensions. For example, a performance can be determined that is characterized by one or more minimum dimensions (e.g. as quantitative values) or by the attainability of one or more predetermined minimum dimensions (e.g. as digital values).

Furthermore, the method can include: determining a change in a vehicle operating parameter, a boundary condition and / or the degree of presence of the user after a first execution of at least one test procedure, and then initiating at least one test procedure, in particular a repetition of the at least one test procedure as an essentially identical or modified (adapted) test procedure, or initiation of a different or modified test procedure. It can be assumed or predicted that a measure of a probable operational readiness, failure probability and / or a performance of the vehicle actuator due to the change in a vehicle operating parameter, a boundary condition and / or the extent of the user's presence will not be unfavorable or not to an undesirable extent has changed.

In the method, one or more features and / or threshold values discussed in the present document can be used depending on a degree of the presence of the user of the vehicle, in particular the driver of the vehicle (in relation to a time interval for executing the at least one vehicle functionality and / or the actuation of the at least one Actuator) can be varied.
With a comparatively low level of presence of the user, for example, a more extensive, more complex and / or more precise test procedure can be initiated and / or a more extensive, more complex and / or more precise measure can be carried out and / or a greater restriction of the at least one functionality can be carried out than for example, if the user is present to a high degree. The degree of presence of the user can be determined and taken into account in several, for example 3 - 5 graduated, dimensions.

A graduated measure, for example qualitative and / or quantitative measure of operational readiness, failure probability and / or expected performance of the actuator is preferably determined in the test procedure. If necessary, a certain risk for a certain application of the corresponding functionality (which applies under the given boundary conditions) can also be determined and taken into account. Particularly preferably, the degree of operational readiness, failure probability and / or the expected performance of the actuator can relate to one or more specific operating modes, loads on the actuator, for example in a specific mode or value ranges of an operating parameter.

Alternatively or additionally, a specific reason, e.g. an identifier for a retrievable energy, an on-board network fault, wear, etc., for possibly insufficient operational readiness or for an increased probability of failure and / or for possibly insufficient performance of the Actuator are determined and taken into account. For example, it is estimated that an at least partially remote-controlled functionality for parking, exiting or maneuvering will be requested in the near future, i.e. within a few seconds or minutes. From this data as well as from other data in the vehicle, e.g. also depending on the determined application, it can be determined that an actuator of the chassis, e.g. the brake system, will (at least probably) be used within certain operating parameters.

For example, several probability measures can be determined for different modes or value ranges of a speed reduction or a steering, which can (at least probably) be used in the case of an automated or remote-controlled braking or steering. Such identifiers are illustrated in the following tables (which can be extended accordingly): Operating parameters for a possible actuation of a braking system No actuation Dismantling <5 km / h Reduction of between 5 km / h - 15 km / h Dismantling> 15 km / h Probability measure that an operation will take place 40% 50% 5% 5% Operating parameters for a possible actuation of a steering system No actuation Wheel setting angle <10 ° Wheel setting angle 11 ° -30 ° Wheel setting angle> 30 ° Probability measure that an operation will take place 90% 5% 3% 2%

In addition, it can be determined for one or more identified cases whether or which alternative actuator can be actuated alternatively or additionally in a certain case, e.g. if the brake system fails. For example, a probability measure for the operational readiness, failure probability and / or expected performance of an alternative actuator or emergency system can be determined and taken into account.

The test procedure for the (first) vehicle can in particular be carried out in a utility operation or customer operation of the vehicle. The information that is dependent on the result of the test procedure can then be made available (only or predominantly) to further (second) vehicles and / or taken into account in the operation of the vehicles that are in a commercial operation or customer operation. A commercial operation or customer operation can be recognized by a predetermined criterion, e.g. relating to the type of use and / or a so-called coding of the vehicle or vehicles.

Depending on the result of the at least one test procedure in the (“first”) vehicle, a measure can be carried out in the vehicle or in one or more additional (“second”) vehicles or in the same (“first”) vehicle at a later time interval, be initiated. The measure in the vehicle or one of the one or more additional vehicles can relate to a system of the same type or a system of a different type. In other words, a measure can be initiated in one or more further vehicles that relates to a system of a different type than the system to which the test procedure in the vehicle related.

Carrying out a measure can include determining (for example, selecting) or adapting a measure and / or a parameter of a measure. For example, depending on the result of the at least one test procedure, a measure, in particular a parameter of a measure in relation to the system of the vehicle can be initiated. The measure can preferably (only, only) be initiated in connection with a possible, in particular anticipated, actuation of the actuator. In particular, the result of the comparison with regard to the selection, the initiation of the measure and / or a parameter of a measure is taken into account.

In particular, the measure can be a so-called fail-safe measure (putting the vehicle or a system of the vehicle in a comparatively safe state) and / or a measure to reduce a disadvantage (e.g. damage) of an (at least most likely) inevitable event , e.g. a breakdown in operation, an accident, etc.

• - Beeinflussen einer Funktionalität umfassend eine automatisierte, fahrerlose und/oder oder zumindest teilweise ferngesteuerte Bewegung (z.B. Fahren, Einparken, Ausparken, Rangieren, Manövrieren) des Fahrzeugs,
• - Beeinflussen - insbesondere Ansteuerung - des Aktors oder einer für den Betrieb des Aktors maßgeblichen Komponente des Fahrzeugs, z.B. des Energiebordnetzes, beispielsweise ein Anpassen der Steuersignale zur Steuerung des zumindest einen Aktors,
• - Übermitteln eines Signals zu einer Recheneinheit außerhalb des Fahrzeugs, beispielsweise mit einer an den Fahrer gerichteten Entscheidungsaufforderung und/oder Entscheidungsempfehlung,
• - Veranlassen oder Verändern einer Außenwirkung des Fahrzeugs, insbesondere einer Signalisierung des Fahrzeugs nach außen.

Depending on the result of the at least one test procedure, a measure (to be understood alternatively or additionally as “action”), in particular a parameter of a measure, is preferably determined in connection with the at least probable actuation of the actuator. Information characterizing the result of the test procedure can be provided in the vehicle and / or in a computing unit located outside the vehicle. Depending on the result of the test procedure, one or more of the following actions can be performed on it (as a measure):

• - Influencing a functionality including an automated, driverless and / or at least partially remote-controlled movement (e.g. driving, parking, exiting, maneuvering, maneuvering) of the vehicle,
• Influencing - in particular controlling - the actuator or a component of the vehicle that is decisive for the operation of the actuator, e.g. the on-board power supply system, for example adapting the control signals to control the at least one actuator,
• - Transmission of a signal to a processing unit outside the vehicle, for example with a decision request and / or decision recommendation directed to the driver,
• - Initiating or changing an external effect of the vehicle, in particular signaling the vehicle to the outside world.

The measure in the one or more second vehicles can relate to one or more devices, in particular a state of a device, of the respective vehicle. For example, the measure can include preparation for a possible use, a change in an operating mode of a device, in particular in a predictive manner. In a simplified example, a measure can include starting, booting, collecting or determining data, etc. with a device, for example a specific system of the second vehicle.

The at least one measure can relate to a device for automated driving. Alternatively or additionally, the measure can relate to a device of the vehicle that deviates from the device of the vehicle for automated driving and / or a device outside the respective second vehicle. For example, the measure for operating the further vehicle can be carried out in relation to a device that is set up to carry out an at least partially redundant functionality or replacement functionality (e.g. emergency functionality) for the actual device for automated driving. The at least one measure for operating the vehicle can also relate to a device of the vehicle that has an at least partially redundant (second) means, for example a further processing unit, a further actuator, etc. for automated driving or for achieving a safe state (" Fail Safe ”), e.g. for the execution of a holding process, safety process, emergency maneuver or the like. Furthermore, the measure can relate to an active or passive safety device for the respective vehicle.

Alternatively or additionally, the measure can include a so-called degradation of a functionality, restriction or blocking of at least one device or functionality of the (second) vehicle. The at least one measure can be prompted to be carried out as immediately as possible, e.g. almost in real time, or to be carried out later. For example, the measure for operating the vehicle can relate to the behavior of the vehicle in relation to its surroundings. In particular, the measure for operating the vehicle relates to the operation of the vehicle with a certain limit value exceeding and / or a certain limit value or a certain degree of automation and / or degree of remote control.

Initiating the measure can include determining, adapting a measure and / or carrying out a measure. The initiation of the measure can provide the data for Include control and / or to carry out the measure. As an alternative or in addition, initiating the measure can comprise determining or adapting a condition for carrying out a measure. A measure can be linked to a condition, the execution of the measure taking place depending on the checking of the condition (possibly only at a later point in time). For example, a condition is determined which should trigger the measure when it (later) applies. The condition for executing the measure can relate to an identifier of the state of the vehicle, the current or expected driving situation of the vehicle, certain environmental data of the vehicle, and / or a traffic rule, etc., in which the at least one measure is carried out or not carried out may or should.

For example, data for initiating the measure are initially determined depending on the evaluation described in this document and the corresponding information is provided in the vehicle (e.g. to a computer unit of the vehicle or to the vehicle from the backend). Alternatively or in addition, the at least one measure can be a measure that can be carried out by a further device, e.g. by a backend or by a traffic infrastructure device in relation to the second vehicle. In particular, the execution of the measure or the measure itself is also part of the procedure.

A probability measure is preferably initially determined as to whether a vehicle function will be actuated in the near future, the vehicle function comprising an automated and / or at least partially remote-controlled movement of the vehicle. In particular, one or more probability measures of several specific types, modes or alternative variants of the use of the functionality can be determined.

Furthermore, the method can include a measure, in particular a change in the vehicle, which is carried out as a function of the result of the at least one test procedure.
For example, an at least partially automated and / or at least partially remote-controlled measure, for example a specific maintenance process in the vehicle or for the vehicle, for example in relation to the actuator of the vehicle or a vehicle functionality, can be carried out. For example, information that is dependent on the result of a test procedure from the vehicle can be transmitted, for example to a backend. For example, if it is determined that a result of a test procedure fulfills or does not fulfill a predetermined condition, information is sent from the vehicle to a backend or another vehicle. Also, depending on the at least one result of a test procedure, remote-controlled access to the vehicle can be requested and / or carried out from a backend, a user device of the user.

The method can include a large number of diverse measures or vehicle functions that are carried out as a function of a result of a test procedure. For example, depending on at least one (comparatively negative) result of the test procedure, remote control of the vehicle, e.g. with regard to controlling the movement of the vehicle, can be requested and / or carried out, which at least temporarily replace an automated (e.g. driverless) movement of the vehicle, to support or supplement. Such remote control itself can, for example, be carried out by a user via a mobile user device and / or by a dispatcher.

The method can also be applied to a parked (e.g. parked) vehicle, in particular if a further predetermined condition is met. For example, at least one step of the method can be carried out if it is determined that a parked vehicle is soon to be or will be moved at least partially in an automated and / or remote-controlled manner.

In particular, a test procedure can be carried out in a (at least predominantly) manually driven vehicle and, depending on the result of the test procedure, a measure relating to one or more other (at the time) automated and / or remotely operated vehicles can be carried out. In a further example, the test procedure can be carried out in a moving, in particular at least partially automated and / or remote-controlled vehicle, and depending on the result of the test procedure, a measure can be taken regarding one or more other parked, stationary or non-automated and / or non-remote-controlled vehicles. e.g. manually driving vehicles are executed.

The at least one test procedure can also be carried out depending on the detection of an activity by the user of the vehicle, in particular the driver of the vehicle, at the driver's seat. For example, if it is recognized that part of the attention of the The user, in particular the driver, is not facing the vehicle or the vehicle guidance system, a test procedure can be initiated, for example. In this case, it can be ensured with an increased probability that the system or an actuator of the system (if necessary) can also be operated sufficiently reliably or safely (even without a possibly necessary intervention by the user of the vehicle). For example, the at least one test procedure can be initiated or carried out when it is recognized that the user of the vehicle is operating a mobile user device at the driver's seat, e.g. carrying out a certain type of activity (speaking, video telephony, playing, writing) with the latter and / or using it a certain amount of attention and / or the direction in which the user is looking are directed at the user device.

• - das mobile Anwendergerät im Fahrzeug während der Fahrt genutzt wird und/oder ein erheblicher Anteil der Aufmerksamkeit des Nutzer dem Nutzergerät zugewendet ist, und/oder
• - das Testergebnis eine bestimmte erste Bedingung und/oder eine zweite Bedingung erfüllt. Beispielsweise kann die erste Bedingung anzeigen, dass die Information für die aktuelle Fahrt mit dem Fahrzeug wichtig ist. Die zweite Bedingung kann anzeigen, dass ein Zustand und/oder Betriebszustand, insbesondere Betriebsbereitschaft eines Teils des Fahrzeugs unterhalb einer gewissen Schwelle ist. Somit kann eine verbesserte, insbesondere eine sicherere, Nutzung eines (des) mobilen Anwendergeräts im Fahrzeug erreicht werden.

The method can include outputting information, for example in the vehicle, to the user's mobile user device or at a dispatcher, the at least one item of information being dependent on one or more results of one or more test procedures and / or being output. Such information can preferably be output on the mobile user device if it is recognized that:

• - the mobile user device in the vehicle is used while driving and / or a significant proportion of the user's attention is directed to the user device, and / or
• - the test result fulfills a certain first condition and / or a second condition. For example, the first condition can indicate that the information is important for the current journey with the vehicle. The second condition can indicate that a state and / or operating state, in particular the operational readiness of a part of the vehicle, is below a certain threshold. Improved, in particular safer, use of (the) mobile user device in the vehicle can thus be achieved.

For example, depending on a result of the test procedure, a functionality of the vehicle or the further vehicle can be influenced, at least including an automated and / or at least partially remote-controlled movement of the vehicle, a release and / or restriction, and / or change and / or blocking at least a performance feature of the functionality.

For example, depending on a result of the at least one test procedure, the corresponding functionality can be released, an appropriate restriction, or at least one feature of the functionality can be changed or blocked. However, two or more test procedures can also be carried out or repeated, for example, as required. A graduated distinction can be made, which can be made in fine steps. In other words, if there is a slight increase in the risk or in the case of the smallest suspected case, the entire functionality does not have to be deactivated. Rather, a step-by-step adaptation of the functionality to the result of one or more test procedures can be carried out in the method. The release, restriction, change or blocking of the corresponding functionality can relate to certain route sections, which are characterized in particular by a (structural) feature, a parameter of a digital map, and / or to certain time intervals. In other words, one or no change in the operation of a further vehicle can be carried out depending on the section of the roadway or the operating state in which it is located.

Preferably, depending on the result of the test procedure, an appropriate, e.g. the cheapest or best possible combination of performance features that can be carried out as perfectly as possible can be selected. This can be carried out according to a predetermined mathematical relationship. There is the advantage that, for example, the best possible functionality can be offered in relation to the user's point of view, which can or would be executable in the given case or under the applicable boundary conditions.

For example, depending on the result of the test procedure in the vehicle, an adaptation or limitation of an (executable) degree of automation and / or degree of remote control of the vehicle or of one or more further vehicles takes place. For example, depending on the result of a test procedure in a vehicle, an admissible and / or impermissible value range for a degree of automation and / or a degree of remote control for the operation of at least a part or a functionality of the vehicle or one or more other vehicles can be determined or adapted.

For example, vehicle settings can be used or it can be assumed that the highest possible degree of automation is desired for an automated and / or at least partially remote-controlled movement of the vehicle. Then said Functionality can be influenced in such a way that the highest possible degree of automation is set, which is possible, for example, with regard to functional reliability or operational safety.

The degree of automation is to be understood in particular as a proportion of the intervention or the influencing of the movement of the vehicle by means of the vehicle, e.g. external sensors (sensors that detect the surroundings) of the vehicle. In other words, the degree of automation can be referred to as the proportion of the driving tasks of a driver that can at least potentially be taken over by the vehicle and that are typically required for said movement of the vehicle. In the context of this document, the term degree of remote control is in particular the proportion of interventions or influencing of the control, in particular movement of the vehicle, from outside the vehicle, e.g. by a computing unit outside the vehicle, for example by means of remote control by a user or dispatcher outside the Vehicle and / or by means of a (central) computer to understand.

For example, it can be taken from vehicle settings or it can be assumed that the highest possible degree of automation is desired for an automated and / or at least partially remote-controlled movement of the vehicle. The said driving functionality can then be influenced in such a way that the highest possible degree of automation is set, which is possible, for example, with regard to functional reliability or operational safety. The adaptation of the degree of automation can relate in particular to a specific automated and / or remote-controlled movement of the vehicle (from the entire set). For example, a portion of the movement of the vehicle that would otherwise have been controlled automatically can then be reduced as a measure. Alternatively or additionally, part of the movement of the vehicle can be explicitly initiated or controlled by the user.

For example, the method includes determining at least one operating parameter with which an actuation of the actuator, in particular with a certain probability measure, is requested. One or more test procedures are then selected and / or a parameter of the at least one test procedure is determined as a function of the at least one determined operating parameter. One or more probability measures can be determined and taken into account that an actuator is stressed, e.g. within a certain value range of an operating parameter of the actuator itself or of the vehicle. For example, depending on the information determined, a suitable combination or a suitable scope of one or more test procedures can be determined.

Furthermore, the at least one test procedure, in particular a parameter of the test procedure, can be determined as a function of age, usage parameters of the vehicle, other usage parameters, e.g. wear of the actuator or a relevant component of the vehicle. For example, the required sequences of processes and / or the interpretation of the result of the test procedure are tightened with the increasing usage parameters of the vehicle.

One or more probability measures can be determined and taken into account, e.g. that an actuator is stressed within a certain value range of an operating parameter of the actuator itself, or an operating parameter of the vehicle. For example, an expedient test procedure can be initiated or carried out in each case. For example, a test procedure can comprise a combination of several test measures. For example, depending on the information determined, a suitable combination or a suitable scope of one or more test procedures can be determined. Furthermore, the at least one test procedure, in particular a parameter of the test procedure, can be determined depending on the age, wear of the actuator or a relevant component of the vehicle. For example, the required sequences of processes and / or interpretation of the result of the test procedure are tightened with increasing use or wear and tear of the vehicle.

For example, the method includes determining a time parameter which is characteristic of a remaining time until the actuation of the at least one system or an actuator, in particular with a corresponding operating parameter and / or probability measure. One or more test procedures are then selected and / or a parameter of the at least one test procedure is determined as a function of the time parameter determined.

A time remaining up to the at least probable actuation of the actuator can also be determined and taken into account. For example, a test procedure, in particular one or more parameters of the test procedure, can be determined as a function of the at least probable, expected time remaining until actuation of the actuator.

In a simple example, if there is a low degree of probability, for example that a braking system of the vehicle has to dismantle more than 5 km / h, only a test procedure can be carried out with regard to the vehicle's electrical system. If there is a medium or higher probability that the vehicle's brake system can or must break down more than 5 km / h, a test procedure can be carried out with regard to the vehicle's on-board power supply system and the brake system itself and / or another actuator.

In a further variant of the method, the at least one test procedure or the result of the test procedure relates to a measure of the operational readiness of the actuator of the vehicle, a power supply for the actuator and / or part of the on-board data network and / or part of the on-board power network and / or part of a certain chain of effects. The result of the at least one test procedure can include explicit information. It can be information, in particular cryptic, processed, in particular encrypted, according to a predetermined code or coding method.

According to a further embodiment, depending on the result of the test procedure, a condition for the operation of the vehicle or one or more other vehicles with a certain degree of automation and / or remote control, in particular for an increase in the degree of automation, is determined. An edition can be understood as a condition for the beginning and / or the continuation of the execution of a certain degree of automation and / or remote control, in particular for an increase in the degree of automation. The condition can identify a condition for an operation, an operating mode, a measure of the driver's condition or (necessary) driver attention, an operating mode of the vehicle that is required or to be avoided, as well as the like, e.g. for the execution of a certain degree of automation and / or a certain degree of remote control. For example, the overlay can identify one or more value ranges or patterns of the parameters in which a degree of automation and / or degree of remote control, in particular a range of values of the degree of automation and / or degree of remote control, is recommended or not recommended and / or is made executable or not executable. An edition can be determined as a chained or chained referenceable code or blockchain code. In particular, the invention comprises checking or controlling a support for operating the vehicle in a (specific degree of automation or remote control degree by means of a cryptographically referenced, in particular chained or chained referenced code. For example, this can be used to ensure that a specific, for the vehicle or for another vehicle and / or degree of automation or degree of remote control certain conditions are met.

In one example of the method, an essentially constant or slowly or rarely changing degree of automation and / or degree of remote control is carried out, the corresponding overlay being varied, in particular adapted, depending on the information provided, in particular for certain first and / or second route sections. In this way, a sufficiently safe, automated or remote-controlled operation of the vehicles, e.g. below a certain risk level, can be ensured.

For example, the support can indicate a certain degree of a presence and / or readiness to drive on the part of the user of the vehicle. Fulfillment of the requirement or the willingness to meet the requirement can be checked (possibly also depending on the result of the at least one test procedure). Depending on the result of the test procedure, different requirements can be determined and / or checked as a condition for increasing the degree of automation or degree of remote control.

For example, a map, vehicle-internal and / or vehicle-external information can (also) contain a condition, e.g. relating to the status of the vehicle, degree of presence of the user, status (e.g. readiness to drive, attention, share of driving tasks, activity) of the vehicle user mark at which a certain degree of automation and / or degree of remote control should or may be achieved, or should not be achieved or may not be achieved.

In one example of the method, information on a certain degree of automation and / or degree of remote control and on at least one requirement for reaching, exceeding or possibly falling below the degree of automation and / or degree of remote control is determined as a function of the information provided.

For example, the availability, activatability and / or activation of a certain degree of automation and / or a certain degree of remote control, depending on the degree of fulfillment of the at least one condition (to be fulfilled in the vehicle or in a further vehicle) can be influenced, in particular controlled.

Depending on the result of the test procedure, information, in particular a request, characterizing a condition for the user of the vehicle, can be output. For example, depending on the result of the test procedure in the vehicle, a request can be issued in the vehicle or in one or more other vehicles to touch one or more operating elements, to hold them, to perform an operating action, for example to touch a pedal of the vehicle with one foot to touch a steering wheel or steering device or a certain control element or combination of control elements, or to operate it in a certain way (possibly only to check the support or control), e.g. touch the steering wheel rim or the steering wheel rim with a torsional force to undergo.

For example, it can be determined whether the user of the vehicle, e.g. within a certain time, e.g. B. 1, 2, 5 10 seconds, the condition met or not met. Thereupon, depending on the fulfillment of the condition, e.g. depending on a condition fulfilled at least to a certain degree, a functionality of the vehicle or the further vehicle can be executed (started, continued) or not executed or limited. For example, a degree of automation and / or a degree of remote control can be restricted, released from a restriction, changed or essentially maintained.

According to a further embodiment, the degree of automation and / or degree of remote control is or comprises a change, in particular change information relating to the degree of automation and / or the degree of remote control. In particular, the change, in particular change information, can identify a change between at least partially or predominantly automated and at least partially or predominantly remote-controlled operation of the vehicle.

The degree of automation and / or the degree of remote control (or a determined identifier for the degree of automation and / or the degree of remote control) can be an increase, a degree of automation or a degree of remote control, an at least partial transition from an at least partially automated trip to an at least partially remote-controlled trip, and / or from an at least partially remote-controlled trip to an at least partially automated trip. In particular, the term “the degree of automation and / or the degree of remote control” can denote a certain increase in the degree of automation and / or the degree of remote control or information relating to the transition between the automation and / or the remote control. This can but does not have to include the respective (absolute) dimensions.

A certain degree of automation and / or degree of remote control can characterize a limit value of the respective degree which should or may at least and / or at most be achieved.

In the method it can be determined, in particular predicted, that an increase in the degree of automation and / or the degree of remote control is imminent, desired or necessary. For example, it can be determined on the basis of a map, vehicle-internal information and / or vehicle-external information that a certain degree of automation and / or degree of remote control (or a certain increase in the degree of automation and / or degree of remote control) is possible, sensible or desired or prescribed.

For example, it is determined, in particular predicted, that a certain degree of automation and / or degree of remote control and / or an increase in the degree of automation and / or degree of remote control exceeding a certain amount in a preceding time interval, e.g. of 1, 5, 15, 30 seconds, is at least likely desired ( aimed at). At least one (selected, specific) test procedure can then be carried out, preferably before the degree of automation and / or degree of remote control and / or before the degree of automation and / or degree of remote control is increased, and the result of the test procedure can be taken into account. One or more measures relating to the operation of the vehicle can then be taken.

According to a further embodiment, the determined degree of automation and / or a degree of remote control, in particular a desired or required increase in the degree of automation or the degree of remote control, is compared with a predetermined condition and, depending on the result of the comparison, one of at least two different test procedures is carried out.

In particular, it is an increase in the degree of automation to at least level 3, 4 or 5 according to BASt, eg from level 0 to level 3, 4, 5; or from level 1 to level 3, 4, 5; or from level 2 to level 3, 4, 5. For example, the test procedure is initiated in one (“first”) vehicle before the degree of automation is increased to level 3. Depending on the result of the test procedure, a measure can be determined for the same vehicle and / or for a further (“second”) vehicle that relates to the transition to degree of automation 3 and / or operation to degree of automation 3. In a simplified case, the measure can include a change in the functional scope, driver information, etc. Preferably, a certain degree of automation of at least one further ("second") vehicle is activated and in particular only when a predetermined result of the at least one test procedure or the comparison in the same ("second") vehicle and / or in another ( "First") vehicle is available.

In particular, a degree of automation and / or degree of remote control of a part of the functionality can be adapted, which may require a possible, at least partially automated and / or remote-controlled actuation of the actuator of the vehicle (at least when corresponding criteria apply).

For example, vehicle settings, settings for a certain functionality of the vehicle, data on the behavior of the vehicle user and / or history data can be determined or, for example, if no contradicting information is available, it can be assumed that the highest possible degree of automation in an automated and / or remote controlled movement of the at least one second vehicle is desired. The said functionality can then be influenced in such a way that the highest possible degree of automation is set, which is possible with a still permissible risk (e.g. with regard to functional reliability or operational safety). E.g. in the case of a risk that fulfills a predetermined condition with regard to a measure of the risk, e.g. a probability of occurrence and / or consequence. The adaptation of the degree of automation can relate in particular to a specific automated and / or remote-controlled movement of the second vehicle.

In one example of the method, a desired degree of automation or desired degree of remote control, e.g. as a certain tendency and / or possible desired restrictions, can be determined. This can be determined depending on a limitation by the traffic situation, type of road, position information, settings for operating the vehicle, an expression of will by the user of information received from the vehicle. Furthermore, a release information characterizing a release of a first route section and / or a second route section for an at least partially automated and / or at least partially remote-controlled driving operation of a vehicle, in particular with or without a specific condition, can be determined. Depending on the desired degree of automation or degree of remote control and the release information (based on the information provided), a certain value of the degree of automation or degree of remote control can be determined, in particular adapted, for the at least one first and / or second route section. For example, depending on the information provided, it can be determined that it is possible or necessary to increase or decrease the degree of automation and / or a degree of remote control at least for a specific route section.

In other words, the degree of automation and / or a degree of remote control, at least one limit value and / or condition for executing a specific value for this, depending on the information provided, in particular for specific first and / or second route sections, can be controlled. A requirement for a degree of automation and / or a degree of remote control can for example be that a certain minimum level of readiness for action, attention, state of a user is required in order to carry out a certain degree of automation and / or a degree of remote control. Such a support can also be controlled as a function of the information provided, in particular for certain first and / or second route sections.

According to a further embodiment, the at least one measure includes influencing the system of the vehicle and / or determining or adapting the current or planned degree of automation or remote control and / or a condition for executing a certain degree of automation or remote control.

In particular, at least one limit value, in particular an adaptation of a predetermined, e.g. last valid limit value, for the degree of automation and / or the degree of remote control can be determined, in particular adapted.

The determination or adjustment of the degree of automation and / or a degree of remote control and / or a limit value for the degree of automation and / or degree of remote control can relate to a future time interval, for example 1, 5, 15 seconds in the near future. In other words, a predictive adaptation of the degree of automation and / or a degree of remote control and / or a corresponding edition can be carried out. This also provides an acceptable lead time (possibly for the user), for example to meet the requirement.

In the method, in particular in the last-described case, the current or planned degree of automation or remote control and / or a condition for executing a certain degree of automation or remote control can also be carried out during operation.

According to a further embodiment, the at least one test procedure relates to the operational readiness, failure probability and / or performance of a possible actuation of a system or an actuator of the vehicle.

According to a further embodiment, the system of the vehicle is a braking system, a steering system, a sensor system and / or a computer system for carrying out an automated and / or remote-controlled operation.

In the case of the at least one test procedure, a measure of the operational readiness, failure probability and / or performance of an actuator of the system can be determined that would be necessary in the event of a possible (during the at least partially automated and / or remote-controlled operation of the vehicle and / or by this operation conditional) actuation of the system and / or actuator of the vehicle, in particular of a specific actuator or a combination of the actuators of a system of the vehicle, occurs or will occur.

According to a further embodiment, the method comprises a comparison of the result of the test procedure with information based on one or more results of the test procedures from the past and the consideration of the result of the comparison in the method.

The results of the test procedures from the past can be results from the test procedures in the vehicle and / or in one or more structurally identical vehicles.

According to a further embodiment, depending on a result of the test procedure, an influencing of a functionality, comprising an at least automated and / or at least partially remote-controlled movement of the vehicle, a release and / or restriction and / or change and / or blocking of at least one performance feature of the functionality, in particular for a certain route or a type of route.

According to a further embodiment, depending on the result of the at least one test procedure, a minimum and / or maximum executable degree of automation, degree of remote control and / or a condition for executing the degree of automation or the degree of remote control for the movement of the vehicle is determined.

The minimum and / or maximum degree of automation that can be carried out, the degree of remote control and / or the at least one condition for executing the degree of automation or the degree of remote control for the movement of the vehicle, in particular for a specific route and / or a specific time interval, e.g. in the preceding time interval in the near future.

According to a further embodiment, the operation of the one or more further vehicles with a certain degree of automation and / or degree of remote control, in particular an execution of a certain change in the degree of automation and / or degree of remote control of one or more further vehicles is dependent on the result of the test procedure (of the system of the Vehicle) determined or adapted. The operation of the one or more other vehicles with a certain degree of automation and / or remote control can be determined or adapted in a certain lane section depending on the result of the test procedure of the vehicle system (e.g. in the past) in the same or a similar lane section.

According to a further embodiment, the method includes determining at least one operating parameter of the system of the vehicle, which in particular has a certain probability measure will be requested, and thereupon a selection of one or more test procedures and / or determination of a parameter of the at least one test procedure as a function of the at least one determined operating parameter.

The at least one operating parameter for operating the system can be an operating mode for operating the system. For example, the operating parameter can indicate that the system of the vehicle is being used (with a certain probability) to carry out a certain type of driving maneuver, parking maneuver and / or maneuvering. For example, the operating parameter for operating the system of the vehicle can be a parameter for controlling the actuator.

According to a further embodiment, the method comprises determining a time parameter which is characteristic of a time remaining until the system of the vehicle is activated, in particular with a corresponding operating parameter and / or probability measure, and then determining a selection of one or more test procedures and / or determining a parameter of the at least one test procedure depending on the determined time parameter.

According to a further embodiment, the at least one test procedure in relation to the system of the vehicle relates to an energy supply of the at least part of the system of the vehicle, to a sensor of the system of the vehicle, to a part of the on-board power supply to which part of the system is connected , and / or an actuator of the vehicle's system.

According to a further embodiment, the at least one test procedure includes causing a specific physical effect, the result of the test procedure being determined as a function of a reaction to the at least one physical effect.

According to a further embodiment, an operating parameter or a range of values of an operating parameter for operating the system of the vehicle or one or more further vehicles is determined or adapted as a function of the result of the at least one test procedure.

For example, depending on the at least one result of a test procedure in the (at least one) vehicle, at least one measure will be carried out in one or more of the further vehicles. The measure in another vehicle can relate to the same system or a system of the same type to which the test procedure in the vehicle has related. For example, at least one measure can be carried out that relates to: an energy supply of at least part of the system of the vehicle or one or more additional vehicles, a sensor of the system of the vehicle or one or more additional vehicles, part of the on-board power supply system on which one part the system of the vehicle or one or more other vehicles is connected, an actuator of the system of the vehicle or one or more other vehicles.

The value range of an operating parameter can be, for example, a minimum value and / or a maximum value. In particular, the value range of the operating parameter can be specified as a mathematical dependency (e.g. as a function of an operating parameter of the vehicle or a further operating parameter).

According to a further embodiment, depending on the result of the at least one test procedure, driver information or information for a user who controls the vehicle or the further vehicle at least partially from outside the vehicle is generated or transmitted. Said information, which is dependent on the result of the at least one test procedure, can be transmitted to a vehicle key and / or a mobile user device of a user of the vehicle.

According to a further embodiment, the method comprises: a detection and evaluation of a driving context and / or a state of the driver of a further vehicle in connection with an automated and / or at least partially remote-controlled movement of the vehicle, and / or a prediction of a probable need to actuate a System of a further vehicle, in particular a determination of at least one probability measure and / or an operating parameter with regard to a possible actuation of the system of the vehicle, and then: reading in and / or taking into account the data characterizing one or more results of the test procedures with regard to the system of the vehicle. For example, one or more results of the appropriate test procedures, e.g. carried out in a comparable driving context in the vehicle (10), can be selected or taken into account.

For example, the at least one test procedure relates to the operational readiness of a (or the) system or an (or the) actuator of the vehicle, a power supply for the actuator and / or part of the on-board data network and / or part of the on-board power network and / or part of a certain chain of effects.

• - eine Testprozedur in Bezug auf die Betriebsbereitschaft eines Teils des Aktors des Fahrzeugs als solches, und/oder
• - eine Testprozedur in Bezug auf eine (zumindest potentiell erforderliche) Energieversorgung des Aktors, und/oder
• - eine Testprozedur in Bezug auf einen Teil des Datenbordnetzes und/oder Energiebordnetzes des Fahrzeugs, der im Zusammenhang mit dem Aktor steht, und/oder
• - eine Testprozedur in Bezug auf einen Teil einer Wirkkette, des Aktors, insbesondere eines Sensors des Fahrzeugs, der bei der (möglichen) Betätigung des Aktors eine relevante Information liefert, und/oder
• - eine Testprozedur, umfassend eine Auswirkung auf die Bewegung des Fahrzeugs, z.B. eine kurze Testbremsung, insbesondere mit einer Auswertung einer Auswirkung.

For example, depending on the at least one operating parameter with which the actuator is actuated and / or depending on a determined probability measure, one of the following test procedures can be requested:

• - A test procedure with regard to the operational readiness of a part of the actuator of the vehicle as such, and / or
• - A test procedure with regard to an (at least potentially required) energy supply for the actuator, and / or
• - A test procedure in relation to a part of the on-board data network and / or on-board energy network of the vehicle, which is connected to the actuator, and / or
• a test procedure in relation to a part of a functional chain, the actuator, in particular a sensor of the vehicle, which delivers relevant information when the actuator is (possibly) actuated, and / or
• a test procedure comprising an effect on the movement of the vehicle, for example a short test braking, in particular with an evaluation of an effect.

Three test procedures or types of test procedures according to advantageous developments are presented below.

The first test procedure comprises recording a first operating parameter, in particular a first data pattern in the vehicle, and comparing the first operating parameter, in particular the first data pattern, with information based on one or more second operating parameters, in particular one or more second data patterns.

For example, a section of temporarily stored data with the relevant first operating parameters, e.g. from a ring memory, can be determined. Such a section of the data can at least partially comprise the data from the past. A section of the temporarily stored data can then be selected when a certain probability of the impending at least partially remote-controlled and / or automated actuation of the at least one actuator is established.

For example, if it is determined that a probability measure for an actuation of an actuator of the vehicle with an operating parameter within certain value limits fulfills a predetermined condition, e.g. is higher than a static or dynamic limit value, the section of the data on the first operating parameters, in particular from a previous time interval, can be called up and evaluated. For example, pattern recognition can then be carried out in the data. The comparison can be carried out with the second operating parameters. These can, for example, be stored reference values, limit values or certain indicators. The second operating parameters can preferably be determined or established on the basis of the multiple first operating parameters from the past. These can be determined, for example, from a statistical evaluation based on roughly identical vehicles and / or one or more actuations of the actuator or a comparable actuator with comparable operating parameters and / or under comparable boundary conditions.

The second test procedure includes driving the actuator with a test control signal, and determining one or more parameters characterizing an effect of the actuator on the test control signal, and comparing at least one parameter characterizing an effect of the actuator on the test control signal with a predetermined condition.

A test control signal can include, for example, a predefined sequence of different control signals. These can be chosen, for example, in such a way that a resulting effect on the movement of the vehicle or side effects (if at all) is limited.

• - eine hydraulischen Größe, insbesondere eine Sequenz oder ein Muster der Druckveränderung in dem Bremssystem, Lenksystem bzw. in einem vertikaldynamischen Aktor. Daraufhin kann ein Abgleich des ermittelten bzw. gemessenen Druckfolgemusters mit einem oder mehreren vorausbestimmten Mustern erfolgen.
• - einen Parameter kennzeichnend eine Bewegung der Bremsbeläge, beispielsweise eine Sequenz oder Muster der Annäherung, Entfernung oder des Anliegens der Bremsklötze an die entsprechende Bremsscheibe. Daraufhin kann ein Abgleich des ermittelten bzw. gemessenen Musters mit einem oder mehreren vorausbestimmten Mustern erfolgen.
• - einen Schall und/oder Körperschall, der auf die Ansteuerung mit dem Test-Steuersignal gemessen wird. Daraufhin kann ein Abgleich des ermittelten bzw. gemessenen Druckfolgemusters mit einem oder mehreren vorausbestimmten Mustern erfolgen.

In a simplified example, a test control signal can be used to initiate a specific (functionally meaningless) pumping back and forth with the brake pump. The effect can then be compared with predetermined conditions, for example with values and patterns based on statistical data. The one or more parameters which are characteristic of the effect of the actuator in the case of a test control signal can be characteristic of:

• a hydraulic variable, in particular a sequence or a pattern of the pressure change in the braking system, steering system or in a vertical dynamic actuator. The determined or measured print sequence pattern can then be compared with one or more predetermined patterns.
• a parameter characterizing a movement of the brake linings, for example a sequence or pattern of the approach, removal or contact of the brake pads with the corresponding brake disc. The determined or measured pattern can then be compared with one or more predetermined patterns.
• - A sound and / or structure-borne sound that is measured in response to the activation with the test control signal. The determined or measured print sequence pattern can then be compared with one or more predetermined patterns.

For example, a comparison of several determined parameters, characterizing an action of the actuator, can be carried out in the case of one or more test control signals.

A comparison of the determined parameters of the effect of the actuator, in particular of a pattern recognized therein such as a time characteristic, mathematical relationships between at least two parameters, quantities, etc. in relation to the effect of the actuator, with specific limit values and / or specific patterns can be carried out .

The comparison can take place with a first limit value or a first data pattern, which is carried out to detect a sufficiently high operational readiness and / or a sufficiently low probability of failure or a sufficiently high expected performance.

The comparison can take place with a second limit value or a second data pattern, which is carried out to detect an inadequate operational readiness and / or an excessively high probability of failure or an excessively low expected performance.

The comparison of the determined parameters of the effect of the actuator can include, for example, a determination of one or more excessively non-linear effects and / or delays.

The comparison itself can be carried out inside the vehicle and / or outside the vehicle, e.g. in the smartphone or a backend, e.g. using the data transmitted for this purpose.

The third test procedure comprises generating a specific changing load and / or a changing voltage at a first point of an on-board power supply system of the vehicle, preferably in the vicinity of the actuator, as well as detecting a reaction of the on-board power supply or of the devices connected to the on-board power supply, preferably at one or more second locations in the vehicle, and an evaluation of the reaction, in particular a comparison with a predetermined condition. The said reaction can also include two or more different, e.g. staggered changes in the vehicle.

It should be noted that the test procedures described (both per se and with regard to their execution in connection with the at least partially automated and / or remote-controlled actuation of the actuator) belong to the scope of the invention. One or more of the test procedures can furthermore be combined with further test procedures or measures not described in detail in this document and can also be carried out without a connection with an actuation of the actuator.

In the method, features or patterns can be recognized which indicate a probability measure for sufficient operational readiness and / or failure probability in relation to the actuator of the vehicle. For example, a probability measure higher or lower than a (first) predetermined threshold and / or an increase or decrease in a probability measure can be recognized as a (second) predetermined threshold. A relevant part of the said distributed system can be, for example, an (at least potentially activatable or potentially required) actuator of the vehicle.

In a simplest case, at least one proportional parameter or a time parameter of how a reaction, which in the simplest case is a measure of the voltage drop, fails at one or more points in the on-board power supply system can be recorded.

• - geringfügig einbricht und sich schnell erholt: OK,
• - stark einbricht und sich schnell erholt: nicht OK,
• - geringfügig einbricht und sich langsam erholt: nicht OK.

For example, the following can be determined when the voltage

• - collapses slightly and recovers quickly: OK,
• - falls sharply and recovers quickly: not OK,
• - collapses slightly and slowly recovers: not OK.

One or more parameters of the reaction with a certain follow-up time, e.g. several seconds after the generation of the said changing load and / or a changing voltage, can also be recorded and evaluated in an area of the vehicle's on-board power supply.

For example, a parameter for operating a system or for controlling the actuator and / or the energy supply of the actuator in the vehicle or in the further vehicle is determined or adapted as a function of the result of the at least one test procedure.

The (again, functionally desired) control of the system or of the actuator can be determined or adapted in connection with the corresponding at least partially remote-controlled functionality of the vehicle if this occurs as expected.

• - eine Betätigung des Aktors, z.B. eine automatisierte oder unmittelbar oder mittelbar ferngesteuerte Bremsung vorgezogen werden, z.B. früher als sonst ausgeführt bzw. geplant, und/oder
• - die Betätigung des Aktors stärker oder schwächer angesteuert werden als dies sonst geschehen würde.

This variant of the invention can also be used alternatively or additionally for improvement, for example for more precise control or for a further increase in safety. For example:

• an actuation of the actuator, for example an automated or directly or indirectly remote-controlled braking, can be brought forward, for example earlier than otherwise planned or carried out, and / or
• - the actuation of the actuator is controlled more or less than it would otherwise.

For example, depending on the prediction of the at least probable need to actuate the actuator of the vehicle and / or depending on the result of the at least one test procedure, a further measure, in particular a parameter of a further measure, is determined in connection with the one at least probable actuation of the actuator.

In one example, the at least one measure can be to control one or more energy stores and / or energy consumers in the vehicle's on-board power supply, in particular in the same strand of the on-board power supply, as well as the at least one actuator for a relevant time interval. For example, an energy store can be temporarily deactivated or made non-activatable and / or storage of energy in an energy buffer store can be initiated.

In another example, the at least one further measure can consist in transmitting or outputting information to the user inside or outside the vehicle.

For example, another measure that can be perceived by the user is carried out at least partially in the same time interval with the execution of the at least one test procedure.

The said further measure perceptible to the user can in particular be a non-functional measure or a measure that is not directly related to the at least likely at least partially remote-controlled or automated movement of the vehicle. For example, the at least one second measure can be a staging measure or a psychologically effective measure, e.g. a distraction measure. In other words, the further measure can be determined in such a way that a time (possibly exceeding a few seconds) for executing a selected test procedure is bridged in the perception of the user. For example, the user is meanwhile occupied with an output, an input, a confirmation of any message, etc. The further measure can also include, for example, a sound output, so that the user's perception distracts from carrying out the test procedure. For example, depending on the result of the at least one test procedure, information is transmitted to a vehicle key and / or a mobile user device of a user of the vehicle.

For example, a change in a display and / or a control element of the vehicle, the vehicle key and / or the user's mobile user device can also take place, which is related to the execution of a remote control functionality of the vehicle. In particular, depending on the result of the one or more test procedures, a map or map view (visible to the user) can be generated or visualized. For example, a map can be generated indicative of the operability of the vehicle in an automated and / or remote-controlled operating mode, in particular indicative of an availability or recommendation (or similarly non-availability or non-recommendation) for operating the vehicle in an automated and / or remote-controlled operating mode. For example, lane sections with certain conditions and / or (permissible, impermissible, recommended, not recommended) degrees of automation and / or degrees of remote control can be identified in the generated map. For example, depending on several results of several test procedures that relate to certain route sections, one or more requirements and / or degrees of automation (e.g. according to BASt or comparable) and / or degrees of remote control on the corresponding road sections of the map (visible, by colors, numbers, etc.) ) are marked.

The information can consist, for example, in signaling a condition and / or warning to the driver and / or indicating an alternative procedure or indicating a condition for further use of an automated or remotely controllable vehicle functionality.

In a further example, the user can be prompted or instructed to carry out a test action (e.g. to be carried out in part by the user). For example, the user can be requested, e.g. via his smartphone, to operate a pedal and / or steering wheel of the vehicle (in a certain way). For example, an extended test procedure with or without a change in the parameters, in particular a calibration of the actuator and / or a specific chain of effects, can thereby be initiated, e.g. at certain time intervals of a few months or depending on the use of the vehicle. For example, certain parameters in connection with the operation of the corresponding functionality of the vehicle can be stored in a non-volatile memory.

For example, the method includes a detection and evaluation of a driving context and / or one or more operating actions or an intention of a driver of the vehicle, and then a prediction of an at least probable need for actuation of an actuator of the vehicle in connection with an automated and / or at least partially remote-controlled one Movement of the vehicle, in particular a determination of at least one probability measure as a function of the recorded driving context, the recorded operating actions and / or the recorded intention of the driver. Such a probability measure can, for example, indicate the probability with which the at least one actuator is actuated, in particular in a certain value range of the intensity and / or in a certain time interval.

For example, based on the recorded driving context, the operator actions and / or the driver's intention, it can be concluded with a (well calculable) probability whether and which at least partially remote-controlled functionality for parking or maneuvering in the near future, i.e. within a few seconds or minutes. From this data as well as from other data in the vehicle, e.g. also depending on the determined application, it can be determined that a certain actuator of the chassis, e.g. the brake system, is (at least likely) actuated within a value range of the operating parameters. A parameter of the inclination of the roadway on which the vehicle is located or on which the vehicle is at least likely to be driven on can also be determined and taken into account. A test procedure can be initiated as a function of a value of the inclination of the roadway on which the vehicle is located or which the vehicle is at least likely to be driven on.

For example, the current driving context is determined, for example, by determining whether the vehicle is in a parking lot or is driving to a parking lot or property. The driver's intention can also be determined, for example, by determining whether the driver uses or will use at least partially automated parking from outside the vehicle, or parks himself. After comparing the information about the driving context, the operator action and / or intent of the driver, it can be assumed (relatively safely) that readiness to brake for automatic braking (even without the driver at his seat) must be guaranteed. One or more test procedures can then be executed at a suitable point in time, in particular before the at least partially remote-controlled functionality is initiated.

The method can preferably be used in connection with the functionality for at least partially remote-controlled parking, maneuvering out of parking spaces or maneuvering, in which the user is outside the vehicle in the vicinity of the vehicle and the vehicle is moved with a mobile user device, e.g. smartphone, smart Close or with the vehicle key, controls.

However, the method also relates to such an automated and / or at least partially remote-controlled actuation of the actuator, with or without the presence and / or readiness for action of a driver inside the vehicle from a great distance, e.g. by a dispatcher and / or outside the vehicle located algorithm, is at least partially remote-controlled.

The automated and / or at least partially remote-controlled actuation of the actuator can be initiated, released or provided from outside the vehicle. The actuation of the actuator can take place more or less immediately, ie with a corresponding control command that is interpreted in the vehicle as a command for the actuation of the actuator, or only indirectly, for example with a control command that, in combination with a further condition, results in a Actuation of the at least one actuator leads.

According to a further aspect, the invention is characterized by a system for operating one or preferably several at least partially automated and / or remote-controlled vehicles, having at least one device provided in one or more vehicles and a computing unit outside the vehicle, the device being in the vehicle and the computing unit is set up to execute an operative connection, and wherein the system is designed to execute the method according to one of the preceding claims. The arithmetic unit outside the vehicle also belongs to the scope of the invention. The computing unit can be configured to initiate a test procedure in the at least one vehicle, preferably be configured to receive and / or determine the result of the test procedure, furthermore to be configured to carry out a measure in the vehicle and / or in another vehicle, preferably in one Large number of other vehicles, depending on the result of the test procedure. The term system in this context refers to a large number, e.g.> 100, 1000, 100000 of vehicles. This is to be distinguished from the term “system of the vehicle”. In particular, the system is or comprises a correspondingly configured information processing system (also) outside the vehicles and / or a digital map (determined or managed outside the vehicles).

According to a further aspect, the invention is characterized by a mobile application device which is designed to operate a (one-sided or two-sided) operative connection with a vehicle, in particular with the vehicle or with the further vehicle, and thereby carry out part of the method. The mobile user device can be designed to carry out at least some of the steps of the method according to the first aspect. Advantageous refinements of the first aspect also apply here to further aspects. In particular, the mobile application device can be designed to determine and / or handle the corresponding data. For this purpose, the mobile application device can have a correspondingly configured wired or wireless interface. The (mobile) user device can comprise a smartphone, a tablet PC, an item of clothing with a suitable electronic device, a smart watch and / or a portable navigation device and so on. A transmitting part and / or a sensor system and / or computing resources and / or a transmitting / receiving unit and / or authentication or authentication method of the mobile user device can advantageously be used or co-used.

According to a further aspect, the invention is characterized by a computer program, the computer program being designed to carry out the method according to the first aspect or an advantageous embodiment of the method according to one or more further features of the method. In particular, the computer program is a software program which, for example, can run as an app (= “application”) for one or more types of computing units outside of the vehicle or vehicles. It can preferably be a brand-specific software program, in particular also designed for handling or with further data for the use of the vehicle, vehicle data or billing data, and / or for comparing or aggregating the further data determined in the method. The computer program product can be designed as an update of a previous computer program which, for example, includes parts of the computer program or the corresponding program code as part of a function expansion, for example as part of a so-called “remote software update”.

According to a further aspect, the invention is characterized by a computer program product which comprises executable program code, the program code executing the method according to the first aspect or an advantageous embodiment of the method according to the first aspect when executed by a data processing device. The computer program product comprises, in particular, a medium that can be read by the data processing device and on which the program code is stored, or at least an encrypted file. According to a further aspect, the invention is characterized by a program product which includes an authorized access right to stored data of the computer program product.

The vehicle is preferably a motor vehicle. This results in several advantages that are explicitly described in the context of this document and several other advantages that are comprehensible to the person skilled in the art. As an exception, the vehicle can also be an agricultural vehicle and / or a combination. Furthermore, the vehicle can be a rail-bound vehicle (e.g. a train). In this case, the invention can also be applied in such a way that “the vehicle” is a car of the train and the “further vehicle” is another car of the train or another train. Furthermore, the vehicle can be an airplane, a helicopter and the like, a watercraft. The vehicle can also be a construction machine and / or a system, e.g. a drilling system for extracting minerals, crude oil, etc. The system or the actuator of the vehicle can correspond to one of the actuators of such a device (not described in detail here).

The invention further comprises all functionalities of the vehicle and / or of the mobile user device that are operated or can be operated appropriately depending on or on the basis of the information determined in the method. Such a functionality of the vehicle can be, for example, a functionality for at least partially automated, at least partially remote-controlled and / or at least temporarily driverless driving, parking, parking, maneuvering. The delivery or use of the functionality can require one or more features or steps of the method. Thus, for example, general or country-specific legal requirements for the operation of an at least partially automated or at least partially remote-controlled functionality of the vehicle can be met.

Preferred embodiments of the invention are explained in more detail below with reference to the accompanying drawings, without restricting the generality. The features of the examples can be combined with any other features described in this document.

The only 1 shows a schematic representation of exemplary constituent parts proposed for carrying out the method. Additionally shows 1 a flowchart of the method according to an embodiment of the present invention. The steps of the method defined by way of example are symbolically assigned to the components of the method (only by way of example).

In the following description of the figures, the same elements or functions are provided with the same reference symbols.

One or more embodiments of the method considered here by way of example relate to at least partially automated and / or remote-controlled driving. However, these can also be based on an at least partially automated and / or at least partially remote-controlled actuation of a system or an actuator of the vehicle which, with or without the presence and / or readiness for action of a driver within the vehicle 10 from a great distance, e.g. by a dispatcher and / or an algorithm located outside the vehicle 10 is at least partially influenced, in particular controlled (remotely controlled).

The automated and / or at least partially remote-controlled actuation of the system or of the actuator can therefore be initiated, released, controlled or regulated from outside the vehicle 10. The actuation of the actuator can take place more or less immediately, ie with a corresponding control command that is interpreted in the vehicle 10 as a command for the actuation of the actuator, or only indirectly, for example with a control command that is combined with a further condition an actuation of the at least one actuator leads. Furthermore, all the features of the method can also be applied to an automated movement of the vehicle 10 - even in the absence of the user or in the presence of the driver. The features of the method can be varied depending on whether or not at least a certain amount of user or driver attention is directed to the vehicle and / or to a driving task.

The system according to the invention optionally comprises at least one computing unit BE arranged at a distance, in particular a backend or what is known as a cloud. In this example, the computing unit BE is designed to carry out a one-way or reciprocal operative connection with the vehicle 10 and / or with further vehicles 20, 30, 40 and / or with the mobile user device MA, MA 'of the vehicle user. The computing unit BE is set up to carry out part of the method together with the vehicle 10 and / or the one or more further vehicles 20, 30, 40. For example, a determination and / or processing, in particular a comparison, of the data can be carried out at least partially by means of the computing unit BE.

A description of the in 1 Schematic procedure illustrated using an example in individual steps. The steps are defined by way of example and can be combined as desired with one another and with all other features of the method.

In a first step S1, a degree of automation and / or a degree of remote control with which the vehicle is operated in a current and / or subsequent time interval is determined.

In this example, the degree of automation or the degree of remote control relates to driving (performing a driving task). Alternatively or additionally, the degree of automation or the degree of remote control can relate to a functionality of the vehicle that does not relate to driving or to functionalities that are largely independent of the perception of a driving task. This means that the degree of automation and / or the degree of remote control also includes the information that it has been changed in a certain way, e.g. changed from a first certain level to a second certain level.

It can also be predicted or determined, based on an operating action, a driving context, vehicle data, position information of the vehicle, that a change, in particular a certain increase in the degree of automation and / or the degree of remote control, is at least likely (e.g. with at least one probability that exceeds a certain limit value) is imminent.

In an optional further step, probability measures for different modes of use of a corresponding functionality and / or a range of values of the operating parameters, characterizing a probable stress on the actuator, are determined in advance.

In an optional further step, a required measure of the probability of failure can be determined and taken into account that a specific actuator must have in the present application so that a specific application can (overall) be carried out with sufficient reliability. For example, a risk in connection with the present application can be determined and then current safety requirements for the actuation of the actuator in the present application can be derived.

In an optional further step, a time interval is determined or estimated which remains until the actuator is actuated. Depending on the remaining time interval, longer or shorter test procedures (without any disadvantage for the user) can be planned and executed.

In a second step S2, depending on the information ascertained, it is determined whether and which of the test procedures are necessary or expedient in the present case. For example, one of several possible test procedures is selected. A parameter for executing the test procedure is determined depending on the information determined. For example, a more extensive test procedure can be determined for a comparatively old and / or comparatively new vehicle than, for example, for a middle-aged vehicle.

In an optional further step, the at least one test procedure is selected and / or parameters of the test procedure are determined in such a way that the test procedure can be used to test (prove) an overall adequate operational readiness, failure probability and / or performance. For example, when other risks in connection with the relevant vehicle functionality decrease, a more stringent test procedure can be determined for the at least one actuator. In doing so, the overall resulting risk can be appropriately reduced.

The at least one test procedure can be a test procedure that relates to the operational readiness, failure probability and / or performance of at least part of the system, the entire system or a further part of the vehicle when the system of the vehicle is operating, relates. Here (as a result of the test procedure) a measure of the operational readiness, failure probability and / or performance of a part of the system, the entire system or another part of the vehicle when operating the system of the vehicle at its possible (at least partially by the automated and / or remote-controlled operation of the vehicle) actuation of the system of the vehicle is determined, in particular predicted.

• - Abweichung von einem statischen oder dynamischen Sollwert oder Kriterium,
• - eine, ein vorausbestimmtes Maß überschreitende oder unerwartet schnelle Veränderung im Vergleich zu einer oder mehreren Testprozeduren aus der Vergangenheit oder aus anderen Fahrzeugen.

In a third step S3 it is recognized within the scope of the test procedure in this example whether a result of the test procedure exceeds a certain threshold listed below:

• - Deviation from a static or dynamic setpoint or criterion,
• - a change that exceeds a predetermined level or is unexpectedly rapid compared to one or more test procedures from the past or from other vehicles.

For example, a first test procedure based on data processing can be carried out first, and if this delivers a result in a suboptimal range, a second test procedure, e.g. a test actuation of the actuator, e.g. a test actuation of the brake system using a test control signal (with or without any actual deceleration of the vehicle).

In a fourth step S4, data in connection with the test procedure, in particular the result of the test procedure, are received and / or determined by a computing unit BE, MA, MA 'outside the vehicle or the vehicles. In particular, a decision can be made in step S4 to which vehicle or vehicles (20, 30, 40) the data characterizing the one or more results of the test procedures are provided or from which vehicle or vehicles (20, 30, 40) they are read in or must be taken into account.

In particular, these data, characterizing the result of the test procedure, can be checked by means of a verification method or processed by means of a so-called blockchain method. In this case, data can be determined for a one-to-one assignment of the results of the test procedures to specific vehicles or to the conditions prevailing during the execution of the test procedure. In step S4 of the method, the data can be offset or aggregated in connection with a plurality of test procedures (in one or more vehicles 10, 10 ′, 10 ″). The data characterizing the result of the at least one procedure are shown directly or indirectly further vehicles 20, 30, 40 (which differ from vehicle 10) are provided and / or linked (linked, assigned) with a digital map, for example with a map layer provided for this purpose.

• - eine Funktionalität, insbesondere ein Starten oder Fortführen einer zumindest teilweise automatisierten und/oder ferngesteuerten Bewegung des Fahrzeugs, freigegeben, eingeschränkt, verändert, mehr oder minder automatisiert ausgeführt, und/oder
• - eine Signalisierung des Fahrzeugs nach außen, z.B. Warnblinker, Licht, angesteuert, und/oder
• - eine Nutzerinformation ermittelt und ausgegeben, und/oder
• - ein Parameter zur bevorstehenden Ansteuerung des Aktors und/oder zum weiteren Betrieb des Aktors (auch für weitere Funktionalitäten) bestimmt oder angepasst.

Depending on the result of the at least one test procedure (this also includes data that characterize these results), one or more of the measures described below are initiated in the vehicle 10 and / or in one or more of the further vehicles 20, 30, 40:

• a functionality, in particular starting or continuing an at least partially automated and / or remote-controlled movement of the vehicle, released, restricted, changed, executed more or less automatically, and / or
• - A signaling of the vehicle to the outside, eg hazard warning lights, lights, activated, and / or
• - a user information is determined and output, and / or
• - A parameter for the upcoming control of the actuator and / or for further operation of the actuator (also for further functionalities) determined or adapted.

In an optional step S5, a measure in the vehicle 10 or in a further vehicle 20, 30, 40 is determined or adapted as a function of the data which characterize the result of the test procedure. Depending on an operating parameter, the driving situation of the at least one further vehicle 20, 30, 40, different measures S6, S7, S8 can be selected and initiated.

For example, the comparison of the result of the test procedure and / or further information in connection with the vehicle 10 can be one or more results of the test procedure in the one or more further vehicles and / or further information in connection with the further vehicles 20, 30, 40, for example, can be executed and taken into account with respective statistical or aggregated values

The one or more steps of the method or data for executing the method can be determined with the mobile user device, for example by means of the app for remote control. For example, a decision can also be made about the execution of the at least one or more test procedures and / or the determination of the parameters of the test procedure in the mobile user device MA, MA 'and / or depending on the data of a mobile user device MA, MA'.

• Bereitstellen der Daten einer Vielzahl der mathematischen Zusammenhänge oder auf Basis der Daten aus einer Vielzahl der ferngesteuerten Bewegung aus einer Anzahl der Fahrzeuge. Dabei kann ein

Dabei kann eine Information auf Basis der Vielzahl der besagten mathematischen Zusammenhänge untereinander und/oder mit weiteren Daten im Zusammenhang mit dem jeweiligen Fahrzeug, Fahrer, Kunde, Randbedingungen der Nutzung der Fahrzeuge abgeglichen werden. Abhängig von dem Ergebnis des Abgleichs kann zumindest ein Merkmal, insbesondere ein Gestaltungsmerkmal, ein Applikationsmerkmal, ein Parameter oder Codiermerkmal eines zweiten weiteren Fahrzeugs und/oder oder eines Computerprogramms für ein zweites Fahrzeug bereitgestellt, verändert, insbesondere zweckmäßig angepasst werden.

Alternatively or additionally, the method in this example can include:

• Providing the data from a large number of the mathematical relationships or on the basis of the data from a large number of the remote-controlled movements from a number of the vehicles. One can
• Comparison can be carried out on the basis of the data from a large number of mathematical relationships. Information can be compared on the basis of the multitude of said mathematical relationships with one another and / or with further data in connection with the respective vehicle, driver, customer, boundary conditions for the use of the vehicles. Depending on the result of the comparison, at least one feature, in particular a design feature, an application feature, a parameter or coding feature of a second further vehicle and / or a computer program for a second vehicle can be provided, changed, in particular suitably adapted.

In the method, for example, depending on the collected data, a corresponding software update for executing a functionality adapted depending on the data can be uploaded to the vehicles and / or mobile user devices that are already in use. A so-called maintenance interval can also be determined or adjusted, a plan for maintenance or replacement can be determined or adjusted and / or a check of a vehicle component (for example by the user or a dealer) can be proposed.

In an optional further step, depending on the result of the test procedure, information can be transmitted to a computing unit outside the vehicle 10, 20, 30, 40, for example the mobile user device MA, MA ', and / or backend BE and taken into account there.
The mobile user device MA, MA 'can be a terminal for (at least partial or temporary) remote control of the vehicle or one or more other vehicles.

Advantages of the present invention are, inter alia, that a functional advantage is provided because the best possible functionality in the specific case can be offered to the user. Furthermore, an appropriate, suitable test procedure can be selected in each case. This can take place as required and not in a disruptive manner, possibly imperceptible to the user, quasi "in the background" or accompanied or covered over with a staging measure.

The method can also provide current results that take into account the currently valid combination of prevailing conditions, condition, e.g. aging condition, wear condition of the vehicle, etc. A change in the vehicle in the course of its life cycle, e.g. due to wear and tear, or due to a software update for various electronic components, repairs or so-called tuning can be recognized by means of the test procedure or the result of the test procedure. A possibly undesirable effect of a change on the automated or remote-controlled operation of the vehicle or another vehicle can be avoided. The vehicle or another vehicle can also be repaired or serviced at a suitable point in time. For example, there is also the advantage that safeguarding highly automated driving as part of vehicle development, e.g. to achieve degree of automation 3 or 4, does not have to take into account "all" theoretically conceivable (or currently not yet conceivable) boundary conditions or aging conditions of the vehicles. In this way, if necessary, a backup run line (in total) can be reduced or used in a more targeted manner.

The at least one selected test procedure is preferably carried out proactively, possibly even before an activation or execution of at least part of the functionality of the vehicle. The driving functionality of the vehicle can be a functionality in which the user or driver at least temporarily, e.g. during the execution of a certain part of a movement of the vehicle, or e.g. for a certain time interval in connection with the execution of a maneuver of the vehicle , cannot be active, e.g. not ready to drive or asleep, is not present in the interior of the vehicle, is outside a certain distance from the vehicle and / or has no visual contact with the vehicle.

The test procedure can relate to a specific actuator itself and / or one or more components that are required for an automated or at least partially remote-controlled actuation of the actuator. These one or more test procedures can be selected as alternatives, situation-adaptive or in addition to one another. A suitable or expedient test procedure can be selected for the expected use of the functionality, for example for a specific time interval in which the at least one automated and / or partially remote-controlled actuation of the actuator of the vehicle is to be expected. A combination (eg of many possible combinations) can also be selected from at least two of the test procedures identified in this document. For example, an identifier can be determined for the time interval at which automated and / or partially remote-controlled actuation of the actuator of the vehicle is to be expected and then a test procedure, in particular one of several possible test procedures, e.g. a first test procedure, a second test procedure or a third Test procedure, can be selected. A test procedure can be selected or executed in such a way that the corresponding result of the test procedure can be taken into account before the (at least potentially necessary) actuation.

In a further example that can be combined with all the features described in this document, the actuator or the actuation of the actuator can relate to a door, a flap, a convertible top (e.g. convertible top), a roof or any extendable device of the vehicle. In a further example that can be combined with all of the features described in this document, the actuator can be a device for energy conversion. Furthermore, the actuator can relate to part of the drive system of the vehicle. For example, the actuator can comprise part of a motor, electric drive, combustion unit and / or a traction battery of the vehicle. Such an actuator can, for example, relate to an energy conversion while driving and / or while the vehicle is stationary. For example, depending on a prediction of an at least partially automated and / or at least partially remote-controlled functionality of the vehicle, a test procedure can be applied to part of an energy conversion system and / or drive system of the vehicle. The ability to activate or an operating parameter of the at least partially automated and / or at least partially remote-controlled functionality of the vehicle can be controlled as a function of the result of the test procedure.

In a further example that can be freely combined with all the features of the invention, the initiation of a test procedure is initiated as a function of a boundary condition for operating the vehicle and / or the result of the test procedure is further processed.

• - State of the vehicle, in particular a (current or expected) performance of at least one component of the vehicle. Such an identifier can be determined and taken into account as a function of the so-called diagnostic data.

In a further example that can be freely combined with all the features of the invention, depending on an execution of the at least one test procedure, a measure is initiated and carried out that includes signaling the vehicle to the outside, in particular in a specific direction or to a specific road user. For example, the said signaling to the outside can include: a light signal in a certain spatial direction, a sound signal in a certain spatial direction, displays, in particular projecting, a two-dimensional or three-dimensional graphic, display of a movable representation, for example an animation, image sequence, causing a display of a Section of a virtual reality for at least one road user.

Dabei kann ein Wahrscheinlichkeitsmaß (z.B. 2 - 8 oder mehrere Abstufungen) geschätzt werden, mit dem eine bestimmte (ferngesteuerte und/oder automatisierte) Ansteuerung eines oder mehrerer bestimmter Aktoren, z.B. des Antriebs, der Vorderradlenkung, Hinterradlenkung, und/oder der Bremsanlage, oder der Vertikaldynamik erforderlich sein wird. Es kann auch ermittelt werden, dass eine bestimmte Beanspruchung des Aktors, z.B. eine bestimmte Bremskraft, bestimmte Beschleunigung und/oder ein bestimmter Lenkeinschlag mit einem bestimmten Wahrscheinlichkeitsmaß benötigt werden wird.

In another example, which can be freely combined with all the features of the invention, a sequence of an exemplary method is explained:

• First, it is predicted that a functionality of the vehicle that includes an at least partially automated and / or remote-controlled movement of the vehicle (e.g. with a certain degree of automation and / or remote control) will (at least probably) be activated in a few seconds or minutes. A probability measure (e.g. 2 - 8 or more gradations) can be estimated with which a specific (remote-controlled and / or automated) control of one or more specific actuators, e.g. the drive, the front wheel steering, rear wheel steering, and / or the brake system, or the vertical dynamics will be required. It can also be determined that a certain load on the actuator, for example a certain braking force, certain acceleration and / or a certain steering angle will be required with a certain degree of probability.

In an optional step, at least one test procedure is selected and / or configured as a function of the information determined. For example, a parameter of the test procedure, e.g. time, number of repetitions, etc. can be determined.

In an optional step, the result of the test procedure initiated is interpreted as a function of which operating parameters of the one or more actuators are at least likely to be required with a certain degree of probability. For example, if a control of the actuator (e.g. the brake system) is imminent with a high degree of probability and / or if it is likely to be a heavy load, the result of the test procedure can be interpreted in different ways, e.g. with different threshold values or conditions are compared.

Depending on the result of the test procedure, e.g. if at least one first predetermined condition is not met or another second predetermined condition applies, said functionality can be appropriately influenced. The functionality is preferably restricted only to the necessary extent and / or imperceptibly for the user. In such a case, a second or renewed test procedure can also be carried out. Alternatively or additionally, depending on the result of the test procedure, a measure can be carried out which increases the operational readiness of the actuator or the probability of failure can be reduced to the appropriate extent. For example, depending on the result of a test procedure, certain energy sources (e.g. a buffer) and / or energy consumers, which are connected to the same energy supply line as the actuator, for example, can be controlled in order to obtain energy (at the appropriate time) and thus the security of the availability of the To increase the actuator. For example, if an increase in the degree of automation of the movement of the vehicle is imminent, at least with a certain probability, one or more suitable test procedures can be planned or initiated.

A prediction of an at least probable need for an automated and / or at least partially remote-controlled actuation of an actuator of the vehicle in connection with an automated and / or at least partially remote-controlled functionality of the vehicle can relate to certain locations, geometric areas, road types (motorways, country roads, urban roads ), Parking spaces or multi-storey car parks.

For example, the initiation of at least one test procedure with regard to the operational readiness, failure probability and / or performance of an actuator of a vehicle, which in particular can be actuated automatically and / or at least partially remotely controlled, in the process depending on what is currently taking place or is imminent, e.g. at least with a certain Probability predicted, driving in a certain place, for example by certain coordinates marked area, certain types of roads, are carried out. For example, a test procedure with regard to the operational readiness, failure probability and / or performance of an actuator of a vehicle can be checked before driving into or for driving into certain locations, areas, types of streets, parking lots, parking garages, etc. In particular, this can take place when the vehicle is driven or is to be driven at least partially in an automated and / or remote-controlled manner.

Alternatively or additionally, driving in a certain location, e.g. area marked by certain coordinates, certain types of streets, parking lots, parking garages, etc. or exceeding certain coordinates with the vehicle, in particular in an at least partially automated and / or at least partially remote-controlled operating mode, depending on the execution of a test procedure with regard to the operational readiness, failure probability and / or performance of an actuator of a vehicle, in particular depending on such a test procedure, allowed (eg enabled) or prevented (eg blocked). The execution of the test procedure and / or an operation of the one or more further vehicles take place depending on the one or more results of the test procedures in certain locations, geometric areas, street types, street types, parking lots, multi-storey car parks. A solution for achieving and / or ensuring the necessary functional reliability or operational safety of at least partially automated or remote-controlled vehicles in certain locations, geometric areas, street types, street types, parking lots, parking garages, etc., etc. can be provided.

The method can be used to meet criteria relating to operational safety, functional safety and / or other known or future homologation criteria for vehicles (better or without extreme effort). A result of the at least one test procedure can also be verified or verifiably processed using what is known as blockchain technology. In this way (e.g. for the user, manufacturer or operator of the vehicles), increased security with regard to the operation of the vehicle and, if necessary, corresponding legal certainty can be achieved.
