Description

The invention relates to a computer-implemented method and a device for determining a control command for controlling a vehicle based on route information from a variety of information sources, a computer-implemented method for managing information sources and corresponding computer program products, an information source management device and a vehicle .

Vehicles can have systems for supporting the driver and/or for at least partially autonomous driving. These systems can issue control commands to control the vehicle, with the system determining the control commands based on appropriate information. The control commands can control the vehicle directly, for example in autonomous vehicles, or can be issued to the driver in order to instruct and/or inform him.

This information can be stored in a memory of the system and can include or be supplemented by information recorded by sensors of the system or the vehicle. Furthermore, traffic information can be received from one or more providers/sources using a network connection. Based on the information and traffic information provided, the system determines the control command.

In particular, information that cannot be detected using the vehicle's sensors, for example because the corresponding objects to be detected are too far away for the sensors, can be requested from the sources in order to enable the system to look ahead at an expected route. Information can also be requested that can be used to supplement and/or check the information that has already been stored and/or recorded.

Since the control commands are based at least in part on the information provided, it is relevant for security reasons to examine this information, evaluate the information and/or evaluate the units, sources and providers themselves in order to identify better and worse information, units, sources and /or to separate providers. Furthermore, it is necessary to limit an amount of information in order to save computing resources.

Computer-implemented methods for determining a control command for controlling a vehicle based on route information provided by a variety of information sources are out DE 10 2008 053 531 A1 , DE 10 2020 215 684 A1 and DE 10 2019 216 734 A1 known.

It is therefore an object of the present invention to provide a computer-implemented method and apparatus for determining a control command for controlling a vehicle based on route information from a variety of information sources that overcome one or more of the aforementioned disadvantages.

According to a first aspect, the task is solved by a computer-implemented method for determining a control command for controlling a vehicle based on route information from a plurality of information sources. The method includes determining a current vehicle position of a vehicle and/or an expected route of the vehicle and receiving route information from a plurality of information sources that characterize a route description of the current vehicle position and/or the expected route. The method further comprises determining an assessment of the route information received from at least one of the information sources and/or at least one of the information sources based on at least one quality criterion, and determining at least one control command for controlling the vehicle based on the assessment, the assessed route information and/or the at least one evaluated source of information. At least one of determining the evaluation and determining the control command can be done using a route algorithm.

Using the proposed method, provided route information and information sources can be evaluated and the control command can be issued based on the evaluation. The evaluation of the route information and/or information sources is based on quality criteria that make it possible to classify/evaluate the quality of the route information and/or the information sources. Accordingly, route information can be assessed as credible and/or current. Other route information can, for example, be classified as outdated and therefore not be included in determining the control command. Furthermore, incorrect route information can be identified in comparison with other route information and possible incorrect assessments of the driving situation can be reduced, in particular eliminated. Particularly with regard to autonomously driving vehicles, a high quality of the route information used is necessary in order to achieve this to enable the highest possible level of safety and accurate assessment of the driving situation and to enable a driving style that is as precise as possible.

The plurality of information sources may include two, three, four or more information sources.

The route information may include information relevant to controlling the vehicle. The route information can in particular include traffic information, map information, weather information and/or status information regarding the condition of the roads. The condition of the road may describe the road as cracked, uneven, having potholes, having oil slicks and/or icy and/or having aquaplaning. Additionally or alternatively, the route information may include publicly available information, in particular that which is relevant for controlling the vehicle.

The route information and/or information sources to be evaluated can be those route information or information sources which characterize the route description of the current vehicle position and/or the expected route.

The route description can include assigning objects, geometries and sizes to coordinates. Furthermore, the route description can include further information relating to the current vehicle position and/or the route, which is particularly relevant for controlling the vehicle.

The control command can be a direct control command or include one by means of which the vehicle is controlled without the driver's intervention and/or which overrides a manual control by the driver. Direct control commands can be used in particular for at least partially autonomous vehicles. Alternatively or additionally, the control command can be or include an indirect control command. The indirect control command can output control information for controlling the vehicle to the driver acoustically, visually and/or haptically. Consequently, the driver can be informed about possible control options. Additionally or alternatively, the control command, in particular the indirect control command, can be sent to one or more units of the vehicle, for example to an Advanced Driver Assistance System.

The route algorithm may be or include a machine learning algorithm. Furthermore, the route algorithm can be or have been trained on training data, the training data comprising a test vehicle position and/or a test route of the vehicle and/or a test vehicle. The training data may further include test route information from test information sources that characterize a route description of the test vehicle position and/or the test route. Furthermore, the training data can include test quality criteria and a test evaluation of the test route information and/or test information sources. Based on the training data, the route algorithm can be trained in such a way that it can evaluate route information and/or information sources based on test quality criteria or quality criteria.

Two, three or more quality criteria can be used to evaluate the route information and/or the information sources.

Furthermore, at least some of the received route information and/or (requested) information sources can be evaluated. Evaluating the received route information and/or information sources may be based on a previously determined and/or received assessment of the route information and/or information sources. Alternatively or additionally, the received route information and/or information sources can be evaluated if they do not have a previous evaluation.

The at least one quality criterion can indicate at least one of a completeness, a credibility, a creation time, a last update time, a responsiveness, an update rate, an availability, a relevance, a correctness and an accuracy of the route information and / or the information sources.

The completeness of the route information may be determined based on comparing a route information request for requesting the route information and the received route information, and/or comparing the route information received from the plurality of information sources. The route information request may be sent to at least one of the plurality of information sources to request the route information.

The credibility of the route information can be determined by comparing the route ckinformation of the information sources, determining a degree of agreement of the compared route information, and determining one of the information sources as unreliable if the degree of agreement is below a predetermined credibility threshold. Alternatively or additionally, the route information can be determined to be unreliable. In particular, the route information from two, three or more information sources of the plurality of information sources can be compared. Alternatively or additionally, predetermined parts of the route information from the information sources can be compared with one another. Alternatively, the entire route information from the information sources can be compared with one another. The route information from the unreliable information source can be at least partially excluded when determining the at least one control command. In particular, parts of the route information from the unreliable information sources can be excluded which do not match the route information from the other information sources.

The creation time can characterize a timestamp of the route information at which the route information was first or initially created by the information source and/or another unit.

The last updated time may indicate a timestamp of the route information when the route information was last updated. The last update time can correspond to the creation time.

The responsiveness may include at least one of a response time and an indication capability of the information sources. The indication capability can indicate whether one of the information sources is set up to output a change in the route information between a point in time when the route information was last requested and a current point in time. For example, route information for the route may have been requested from one of the information sources, whereby there are no traffic-obstructing objects on the route at the time of the request. After the request time, the information source receives an update that there is now a fallen tree on the route. Accordingly, the information source can respond to this request and notify the unit that requested the route information of the change in the route information. The response time can indicate how long there is between the receipt of this update of the route information (here the fallen tree) at the information source(s) and the notification being issued to the unit.

The update rate can indicate the time intervals at which the route information from the information sources is updated.

The availability of the route information is determined according to the invention based on at least one of accessibility, a transmission time for sending the route information request to one or more information sources, a processing time for processing the route information request and a transmission time of the requested information sources. The accessibility can include temporal and/or spatial accessibility, in particular by means of a network or one or more communication networks. The transmission duration is the time period between a transmission time of the route information request to one or more of the information sources and a reception time at the information source or sources. The route information request may be sent by the vehicle and/or a corresponding device in the vehicle. The transmission duration is the time period between sending the route information from the information source(s) to a route information receiver, in particular to the vehicle or the device. The processing time may be a period of time between receiving the route information request and/or updated route information and outputting the route information.

The relevance of the route information can be determined based on the route information relevant to the vehicle position and/or the route. Not all route information is relevant at all times. In particular, route information can be requested by means of the route information request and the one or more information sources send route information in response to the request, which includes more than the requested route information. Alternatively or additionally, less route information may be included. Furthermore, the route information can be provided in various file formats by the information sources, with only certain file formats being processable for the vehicle and/or the device. Consequently, route information that cannot be processed is of less relevance than route information that can be processed are shareable. The relevant route information can be determined in advance.

According to the invention, the accuracy of the route information is determined based on evaluations of units, networks and/or users using the route information and/or the information sources. The devices (such as other vehicles and smartphones), networks and users can evaluate route information and/or information sources. This evaluation can indicate the quality of the route information and/or the information source(s). Alternatively or additionally, the accuracy of the route information can be determined based on a comparison with sensor data from sensors of the vehicle and the route information.

The accuracy of the route information can be determined based on an association of route information with location coordinates. For example, an accident may have been reported. If the location coordinate only corresponds to a town or a street, only a specific area can be estimated where the accident is. On the other hand, more precise location coordinates, which limit the area to a few meters, can describe the accident site more precisely. Depending on the driving situation, a higher degree of precision of the route information and the location coordinates may be necessary.

The route information and/or the information sources with an evaluation below a predetermined evaluation threshold can be at least partially excluded when determining the at least one control command. Accordingly, a distinction can be made as to whether, for example, an information source generally has a rating below the rating threshold and is therefore generally excluded, or whether only the most recently requested route information is below the rating threshold, but previous route information was above the rating threshold. Consequently, route information and/or information sources can be at least partially excluded.

The method can further comprise requesting route information from the plurality of information sources, in particular after determining the control command based on the evaluation, the evaluated route information and/or information sources. The query may be based on the rating, the rated route information and/or information sources. In particular, the request can be a request for those route information and/or information sources whose evaluation is equal to and/or above the predetermined evaluation threshold. Accordingly, future requests for route information can be determined based on experience with past requests. If a first source of information provides inadequate or poorly rated route information in a first request and/or more often, this source of information can generally be excluded from further inquiries in order not to have to process and/or take into account the poorly rated route information in the future.

The information sources can be accessible via a network and/or can be designed as cloud providers. Alternatively or additionally, the information sources can include other vehicles, smartphones, providers and the like that provide route information.

The route information can include at least one of traffic information, map information, weather information and traffic obstruction information, the traffic obstruction information in particular characterizing objects obstructing traffic. The route information may include route description information that is freely and/or publicly available. The traffic obstructing objects can be objects that pose a safety risk to the driver and/or the vehicle. The objects obstructing traffic can be fallen trees, branches, tires, stones, animals and the like.

The route information can characterize information regarding the route description that is located outside of a detection range of the vehicle and/or of at least one sensor of the vehicle. Vehicles may have sensors to detect various parameters and/or objects inside and outside the vehicle. These sensors have a predetermined range, so it can happen that not the entire surrounding area is detected, for example because the view is blocked by other vehicles or the further course of the route is out of range. Consequently, using such route information, an improved predictive view of the route can be made possible.

The task is solved according to a second aspect by a computer-implemented method for managing information sources, comprising receiving route information from a plurality of information sources, which characterize a route description of a position and/or a route, evaluating the route information received from at least one of the information sources and/or at least one of the information sources based on at least one quality criterion, and providing an assessment based on the assessed information sources. The step of evaluating and/or providing the evaluation can be carried out using a route algorithm.

Previously described features relating to the method according to the first aspect can also be implemented as features of the method according to the second aspect. Likewise, features of the second aspect can be implemented as features of the method of the first aspect.

In particular, the position and/or the route can be a vehicle position and/or route of a vehicle.

The object is further solved according to a third aspect by a computer program product comprising program code sections for executing a computer-implemented method according to the first and/or the second aspect when the computer program is executed by at least one processor.

The object is further solved according to a fourth aspect by an information source management device, comprising at least one processor which is set up to: receive route information from a plurality of information sources that characterize a route description of a position and / or a route, determine an evaluation of at least one route information received from the information sources and/or at least one of the information sources based on at least one quality criterion, and providing the evaluation of the route information and/or the information sources and/or the evaluated route information. The processor can carry out the evaluation and/or the provision of the evaluation using a route algorithm.

The information source management device may be further configured to request route information from the plurality of information sources based on a route information request and to evaluate the route information received from the information sources in response to the route information request. The route information request may be received by a vehicle. Based on the determined assessment of the route information, the information source management device can be set up to provide the assessment and/or the route information, in particular to the vehicle according to the sixth aspect and/or a device for determining according to the fifth aspect. In particular, the information source management device can be set up to provide route information whose evaluation is equal to and/or greater than a predetermined evaluation threshold. The rating(s) may be pre-saved and/or determined.

Previously described features of the first and second aspects can be designed as features of the third and fourth aspects. Likewise, features of the third and fourth aspects can be designed as features of the first and second aspects.

At least one or more of the information sources and/or the information source management device may be configured to provide the route information via a network. In particular, the one or more of the information sources and/or the information source management device can be set up to additionally or alternatively provide the route information via near-field communication. Near-field communication can be used in particular when the connection quality with a network used is below a predetermined value and/or there is a network error. Consequently, the route information can be provided despite poor connection quality and/or a network error.

The object is achieved according to a fifth aspect by a device for determining a control command for controlling a vehicle based on traffic information from a plurality of information sources. The device includes a position sensor, which is set up to detect a current vehicle position of the vehicle, and a transceiver. The transceiver is for receiving route information from a plurality of information sources that characterize a route description of the current vehicle position and/or an expected route of the vehicle, and/or receiving an assessment from an information source management device that contains at least one of the route information received from the information sources and/or or at least one of the sources of information evaluated, set up. The device further comprises a processor which is set up to evaluate at least one of the pieces of information route information received from sources and/or at least one of the information sources based on at least one quality criterion, and determining at least one control command for controlling the vehicle based on the evaluated route information and/or the at least one evaluated information source. The information source management device may be an information source management device according to the fourth aspect. The processor can carry out the evaluation using a route algorithm.

The object is further solved according to a sixth aspect by a vehicle comprising a device according to the fifth aspect and / or a processor for executing a method according to the first aspect and / or a computer program product according to claim according to the third aspect is set up.

The 1 shows a device 100 comprising a memory 110, a transceiver 120, a processor 130 and a position sensor 140. The memory 110 is set up to store information and/or computer program products. The transceiver 120 is set up to send and receive data. The position sensor 140 is set up to determine a current vehicle position of the vehicle 300. For this purpose, the position sensor 140 can be a GPS sensor and/or receive position information. Furthermore, the processor 130 is set up to access and communicate with the various units of the device 100. In particular, the processor 130 is configured to execute a stored computer program product stored on the memory 110. The device 100 can be included in a vehicle 300.

The 2 shows first to third information sources 220, 220, 230 and the vehicle 300. The information sources 210, 220, 230 can be designed as cloud providers, servers, vehicles and / or other devices that are designed to provide route information. Furthermore, the information sources 210, 220, 230 can be set up to communicate with one another and/or other units, in particular the vehicle 300, via a network.

The route information may include information relevant to controlling the vehicle 300. The route information further characterizes a route description of a current vehicle position and/or an expected route of the vehicle 300.

The route information can in particular include traffic information, map information, weather information and/or status information regarding a condition of the roads, the current vehicle position and/or the expected route. The condition of the road may describe the road as cracked, uneven, having potholes, having oil slicks and/or icy and/or having aquaplaning. Additionally or alternatively, the route information may include publicly available information, particularly that relevant to controlling the vehicle 300.

The device 100 included in the vehicle 300 is designed to determine a control command for controlling the vehicle 300 based on route information from a variety of information sources, in particular the first to third information sources 210, 220, 230.

The current vehicle position of the vehicle 300 is determined using the position sensor 140. The transceiver 120 further sends a route information request to at least one of the first to third information sources 210, 220, 230. The route information request may include position information that characterizes the current vehicle position and/or an expected route. The expected route can be determined by the processor 130 based on the current vehicle position, a destination input by a driver of the vehicle 300 and/or a forward-looking view of the vehicle 300.

The requested first to third information sources 210, 220, 230 receive the route information request, process it and in response send corresponding route information to the device 100, in particular the transceiver 120. The transceiver 120 can alternatively request only one, two, four or more information sources regarding route information .

Alternatively and/or additionally, the transceiver 120 is set up to receive an evaluation from an information source management device 400 (see 3 and 4 ), which evaluates at least one of the route information received from the information sources 210, 220, 230 and/or at least one of the information sources 210, 220, 230 and/or provides a corresponding evaluation.

The processor 130 is set up to evaluate the route information received from at least one of the information sources 210, 220, 230 and/or at least one of the information sources 210, 220, 230 based on at least one quality criterion. Furthermore, the processor 130 is set up to determine at least one control command for controlling the vehicle 300 based on the evaluation, the evaluated route information and/or the evaluated information sources 210, 220, 230.

The control command can include a direct and/or indirect control command. The direct control command is a control command by which the vehicle 300 is controlled directly. In particular, the direct control command can override control by the driver of the vehicle 300 and thus incapacitate the driver. The direct control command can be used in particular in at least partially autonomous vehicles. The vehicle 300 can be a car, bus, scooter, motorcycle and/or at least partially autonomous vehicle. The indirect control command can be a control command that can be used by other units, for example an Advanced Driver Assistance System. Additionally or alternatively, the indirect control command may include control information for controlling the vehicle 300, which is output to the driver acoustically, visually and/or haptically in order to inform the driver about possible driving maneuvers and/or a driving situation.

The at least one quality criterion can be based on at least one of a completeness, a credibility, a creation time, a last update time, a responsiveness, an update rate, an availability, a relevance, a correctness and an accuracy of the route information and / or the information sources 210, 220, 230 point out. In particular, the quality criteria can be used to evaluate the quality of the route information received and/or the requested information sources 210, 220, 230.

The processor 130 is set up to carry out the evaluation of the route information, the information sources 210, 220, 230 and/or the determination of the control command using a route algorithm. The route algorithm may include and/or be a machine learning algorithm (artificial intelligence, AI). Furthermore, the route algorithm can be trained based on training data, such that the route algorithm can carry out the aforementioned steps of determining the evaluation and/or the control command.

The vehicle 300, in particular the device 100, is set up to communicate directly with the first to third information sources 210, 220, 230. Alternatively or additionally, the vehicle 300, in particular the device 100, can be set up to communicate with the information source management device 400.

The 3 shows the information sources 210, 220, 230, the vehicle 300 and the information source management device 400. Unlike in the 2 is the information source management device 400 in communication with the first to third information sources 210, 220, 230, evaluates the received route information and / or the information sources based on at least one quality criterion and provides a corresponding evaluation, in particular to the vehicle 300 and / or the device 100 Previously described features of the units of the device 100 may be embodied as features of the information source management device 400 and are therefore not repeated here. Advantageously, the vehicle 300, in particular the device 100 according to 3 communicate with the information source management device 400 and receive the evaluation and/or the evaluated route information from it. Alternatively or additionally, the information source management device 400 can be set up to provide, based on the route information request of the vehicle 300, in particular the device 100, those assessments and/or evaluated route information which has an assessment equal to and/or greater than an assessment threshold sen. Consequently, a preselection of the route information and/or information sources already takes place by means of the information source management device 400. Accordingly, only part of the route information is sent and/or provided by the information source management device 400 to the vehicle 300, in particular the device 100.

The 4 shows a schematic structure of the information management device 400 with a memory 410, a transceiver 420 and a processor 430. The memory 410 is set up to store information, in particular route information and/or evaluations of the route information and/or the information sources 210, 220, 230. The transceiver 420 is set up to communicate with other external units and networks, in particular with the vehicle 300 and/or the device 100. The processor 430 is configured to carry out the following method for managing the plurality of information sources. Furthermore, the processor 430 is set up to execute a computer program product stored in the memory 410.

The following example describes requesting the route information, evaluating the route information and/or information sources and determining at least one control command.

The vehicle 300 is on a road and has received a destination input from the driver of the vehicle 300. The vehicle 300 determines a route based on the destination input. Furthermore, a route information request is sent to the first to third information sources 210, 220, 230 and/or the information source management device 400 by means of the transceiver 120. The route information request includes the current vehicle position, the specific route and specifications regarding the information required for autonomous driving of the vehicle 300. The route information can be specified in such a way that information that is already available (for example information stored in the memory 110 and/or information recorded by one or more sensors of the vehicle 300), which is used by the vehicle 300 to control the vehicle, is replaced by the route information is at least partially supplemented and/or checked.

In the present example, weather information along the route is requested from the first to third information sources 210, 220, 230 using the route information request. The route information request may be sent to at least one of the first to third information sources 210, 220, 230 and/or all. Additionally or alternatively, the received route information can be used at least partially or completely to determine the control command.

The weather information describes rain and aquaplaning in an area ahead of the route at a current time T1 along the route. Accordingly, the autonomously driving vehicle 300 can provide a lower travel speed in the area of aquaplaning to increase safety. However, route information may change over time. The vehicle 300 needs a predetermined time to reach the aquaplaning area, so that at the time the area is reached, the route information is or can no longer be up-to-date and/or needs to be checked.

To evaluate one of the first to third information sources 210, 220, 230, the quality criterion of responsiveness can be used to evaluate a quality of the route information and/or the corresponding information source. The first to third information sources 210, 220, 230 can receive new information, in particular route information, at regular and/or irregular time intervals, for example from other vehicles, networks, smartphones and/or other providers of corresponding information. If one of the first to third information sources 210, 220, 230 determines that existing route information is changed due to new information, the first to third information sources 210, 220, 230 can be set up to send updated route information to one or more vehicles have previously requested the route information to be updated. This corresponds to the responsiveness of the first to third information sources 210, 220, 230. Alternatively or additionally, the responsiveness may further include a response time that characterizes a period of time. This period begins with receiving the new information for updating the route information at the first to third information sources 210, 220, 230 and ends with receiving the updated vehicle information at the one or more vehicles.

At a later time T2, the first to third information sources 210, 220, 230 receive updated weather information based thereon point out that there is no longer any aquaplaning in the area. The first information source 210 sends the updated route information to the vehicle 300 in order to inform the vehicle 300, in particular the device 100, that aquaplaning is no longer present. On the other hand, the second to third information sources 220, 230 do not send updated route information or send the updated route information at a time T3. However, the time T3 is a time at which the vehicle 300 has already entered or left the area. Consequently, the updated route information from the second and third information sources 220, 230 was received too late to enable the vehicle 300 to drive proactively.

Based on the different responsiveness of the first to third information sources 210, 220, 230, the processor 130 determines that the first information source 210 receives a better rating than the second to third information sources 220, 230. A better or worse rating can be expressed in the form of a rating score. Additionally or alternatively, the rating can be compared with a rating value. The processor 130 is set up to exclude those route information when determining the control command whose evaluation is below a predetermined evaluation threshold. Accordingly, only part of the received route information is taken into account for determining the control command and computer resources can be saved. Furthermore, a possible misinterpretation and/or incorrect prediction of the route is reduced, in particular eliminated, thereby improving the safety of the vehicle 300 and the driver.

The 4 shows a schematic method 500 for determining a control command for controlling a vehicle based on route information from a variety of information sources. The method 500 includes determining 510 a current vehicle position of a vehicle 300 and/or an expected route of the vehicle 300, and receiving 520 route information from a plurality of information sources 210, 220, 230 that provide a route description of the current vehicle position and/or the characterize the expected route.
