Definitions
- the present invention relates, inter alia, to a method for operating an automated vehicle as a function of the precise position or as a function of a signal which represents a failure to determine this precise position.
- the method according to the invention for operating an automated vehicle comprises a step of determining a rough position, a step of detecting an operating state of the automated vehicle and a step of checking whether an exact position can be determined based on the rough position, depending on the operating state.
- the method further comprises a step of determining the precise position if the precise position can be determined, or a step of providing a signal which represents failure to determine the precise position if the precise position cannot be determined, and a step of operating of the vehicle, depending on the exact position or depending on the signal.
- An automated vehicle is understood to mean a vehicle which is designed in accordance with one of SAE levels 1 to 5 (see standard SAE J3016).
- a coarse position is to be understood as a position which has a certain blurring. This is, for example, a few meters and can be up to a few hundred meters, depending on the surroundings of the automated vehicle (high buildings, tunnels, etc.).
- a rough position is to be understood in particular as a position which is so imprecise that the automated vehicle is not automated (according to one of SAE levels 1 to 5) can be operated, although this is intended and / or desired, for example, by an occupant of the automated vehicle.
- An exact position is to be understood as a position which is so precise within a specified coordinate system, for example WGS84 coordinates, that this position does not exceed a maximum permissible uncertainty.
- the maximum blurring can depend on the surroundings, for example.
- the maximum uncertainty can depend, for example, on whether the automated vehicle is operated manually or partially, highly or fully automated (corresponding to one of SAE levels 1 to 5).
- the maximum fuzziness is so small that, in particular, safe operation of the automated vehicle is guaranteed.
- the maximum fuzziness is, for example, of the order of about 10 centimeters.
- An operating state of the automated vehicle is, for example, an automation level (according to one of SAE levels 1 to 5) of the automated vehicle and / or a current speed of the automated vehicle and / or a current lateral and / or longitudinal acceleration and / or an activated or .
- deactivated driving function such as an (adaptive)
- Cruise control system etc.
- Detecting the operating state is to be understood, for example, as reading out one or more control devices which provide a corresponding signal (for example high beam is activated).
- Operating the automated vehicle includes, for example, executing safety-related functions ("arming" or triggering an airbag, tightening a seat belt, executing an emergency stopping process, etc.) and / or executing so-called driver assistance functions (here, for example: executing a lane departure warning, etc.) .) and / or an automated transverse and / or longitudinal control and / or determining and / or following a trajectory for the automated vehicle, etc. to understand.
- safety-related functions "arming" or triggering an airbag, tightening a seat belt, executing an emergency stopping process, etc.) and / or executing so-called driver assistance functions (here, for example: executing a lane departure warning, etc.) .) and / or an automated transverse and / or longitudinal control and / or determining and / or following a trajectory for the automated vehicle, etc. to understand.
- the method according to the invention advantageously achieves the object of providing a method for operating a vehicle.
- This object is achieved by means of the method according to the invention by making the operation of the vehicle dependent on the exact position or as a function of the signal, it being checked in advance whether an exact position can be determined based on the rough position and as a function of the operating state.
- the exact position is only determined as precisely as is necessary depending on the operating state. This also leads to a faster and more efficient determination of the exact position.
- the method thus overall reduces the consumption of resources for determining the exact position and enables the automated vehicle to be operated more safely, since the corresponding information is available more quickly.
- Another advantage of the method according to the invention is an improved assessability of the so-called “map matching performance”. Parameters (such as limit values for similarity metrics) can be statistically determined and applied from the fleet data available on the cloud side.
- the coarse position is preferably determined by means of an environment sensor system and / or by means of a location system.
- An environment sensor system is to be understood as at least one video and / or at least one radar and / or at least one lidar and / or at least one ultrasound and / or at least one further sensor which is designed to detect an environment of an (automated) Vehicle, this environment in particular comprising localization features, in the form of environment data values.
- a localization feature is to be understood, for example, as an object (traffic sign, infrastructure features [guardrail, curve course, tunnel, bridges, etc.], building, etc.) which can be detected and / or classified or assigned by means of a vehicle environment sensor system.
- the environment sensor system includes, for example, a computing unit (processor, main memory, hard disk) with suitable software and / or is connected to such a computing unit.
- a localization feature is additionally or alternatively, for example, a road course (number of lanes, curve radius, etc.) and / or a pattern of several - for example repeating - objects (for example a characteristic sequence of traffic signs, etc.).
- a positioning system is to be understood as meaning, for example, a global navigation satellite system (GNSS), this system being designed for position determination and navigation on earth and / or in the air - by receiving signals from navigation satellites and pseudolites.
- GNSS global navigation satellite system
- the coarse position is preferably determined relative to a first map.
- Determining the coarse position by means of environment sensors is to be understood, for example, that localization features (for example signs with street or city names) detected by means of the environment sensor system are used with a map that shows the corresponding localization features (see above: the corresponding street and / or city names; Buildings, etc.) can be compared.
- the map corresponds to the first map, a first map being understood to mean, for example, a digital map which is present in the form of (map) data values on a storage medium.
- the map is designed, for example, in such a way that one or more map layers are included, one map layer showing, for example, a map from a bird's eye view (course and position of roads, buildings, landscape features, etc.).
- Another map layer comprises, for example, a radar map, the localization features which are included in the radar map being stored with a radar signature.
- Another map layer comprises, for example, a lidar map, the localization features which are included in the lidar map being stored with a lidar signature.
- the map is designed in particular in such a way that it is suitable for navigating a vehicle, in particular an automated vehicle.
- Determining the coarse position relative to the first map is to be understood, for example, as mapping the coarse position in the first map, this position being determined, for example, with a blurring in the form of an area covered.
- the rough position is determined by means of an environment sensor system and by means of a location system, for example by determining a first rough position by means of the location system and then checking it for plausibility using detected location features (for example by comparing a background color of traffic signs if the first rough position - relative to the first map - driving on a motorway suggests, etc.). The first rough position is then determined as the rough position if the plausibility check is successful.
- the operating state preferably includes a predetermined safety requirement, the exact position being determined as a function of the predetermined safety requirement.
- a predetermined safety requirement is to be understood as meaning, for example, the specification of a maximum uncertainty of a position determination.
- the security requirement is provided as a signal (when activating a corresponding function, etc.), for example.
- the exact position is preferably determined by means of a second map, the second map being selected as a function of the rough position and / or as a function of the operating state.
- a second map is to be understood as meaning, for example, a section of the first map, only this section being used to determine the exact position.
- the second card is to be understood as a card that is independent of the first card.
- the second map is designed in particular in such a way that it is suitable for navigating an automated vehicle.
- the individual map layers include, for example, localization features with a GPS position, this position being precisely known (in the sense of an above-mentioned exact position).
- the device according to the invention is set up to carry out all steps of the method according to one of the method claims for operating an automated vehicle.
- the device is designed, for example, as a control unit of the automated vehicle and comprises a computing unit (processor, main memory, hard disk) and suitable software to carry out the method according to one of the method claims.
- the device comprises a transmitting and / or receiving unit which is designed to exchange data values, in particular with an external server or a cloud.
- the device additionally or alternatively comprises, for example, a data interface to exchange data values with a transmitting and / or receiving unit of the automated vehicle.
- the device is designed, for example, as a computing unit (server, cloud, etc.) arranged externally relative to the automated vehicle.
- the coarse position is determined, for example, by receiving localization features from this automated vehicle detected by means of an environment sensor system of the automated vehicle and comparing them with a map which includes the corresponding localization features.
- the operating state of the automated vehicle is recorded, for example, by receiving the operating state as data values from the automated vehicle.
- Operating the automated vehicle is to be understood here, for example, as providing a signal in such a way that the automated vehicle can call up and / or receive this signal from the device, the signal comprising or representing a rule for operating the automated vehicle.
- a computer program comprising instructions which, when the computer program is executed by a computer, cause the computer to execute a method according to one of the method claims for operating an automated vehicle.
- the computer program corresponds to the software comprised by the device.
- FIG. 1 shows an exemplary embodiment of the method according to the invention for operating a vehicle in the form of a flowchart.
- FIG. 1 shows an exemplary embodiment of a method 300 for operating 340 an automated vehicle.
- the method 300 starts in step 301.
- step 310 a coarse position is determined.
- step 320 an operating state of the automated vehicle is recorded.
- step 330 it is checked whether an exact position, starting from the rough position, can be determined as a function of the operating state. This is followed by step 332 if the exact position can be determined, or step 334 if the exact position cannot be determined.
- step 332 the exact position is determined.
- step 334 a signal representing failure to determine the exact position is provided.
- step 340 the vehicle is operated depending on the exact position or depending on the signal.
- the method 300 ends in step 350.
