Definitions
- the present invention relates to a method for controlling a front collision assistance system for a motor vehicle.
- the invention further relates to a corresponding front collision assistance system and a motor vehicle equipped therewith.
- a possible method is described, for example, in US 2019/0 143 967 A1.
- a first vehicle is operated based on a sensor data set of the first vehicle.
- this sensor data set it is determined in the first vehicle that a second vehicle is covering part of a field of view of a corresponding sensor of the first vehicle.
- a corresponding partial data record is then requested from the second vehicle for this part.
- the sensor data set of the first vehicle is updated with this partial data set.
- US 3021/0 116 931 A1 describes a travel assistance system.
- This includes a receiving unit for receiving vehicle information about parked or stopped vehicles.
- This vehicle information indicates detection of a parked or stopped vehicle on a travel road. That includes further Travel support system a prediction unit that predicts the length of stay of the parked or stopped vehicle based on the vehicle information and a duration prediction model.
- US 2015/0253 772 A1 describes a method in which a limit for the availability of an autonomous driving function of a vehicle is continuously calculated based on a planned route. Vehicle surroundings information, vehicle dynamics parameters, map data with associated speed limit and infrastructure information, real-time traffic information or real-time weather information associated with the planned route are also taken into account. Information regarding any changes in the calculated limit for the availability of the autonomous driving function along the planned route is then output via a human-machine interface in a passenger compartment of the vehicle.
- the object of the present invention is to enable particularly convenient use of a front collision assistance system in the motor vehicle.
- the method according to the invention is used and can therefore be used to control a front collision assistance system for a motor vehicle.
- This front collision assistance system is set up to recognize obstacles ahead in the direction of travel of the motor vehicle based on environmental data recorded by an environmental sensor system of the respective motor vehicle and to automatically initiate at least one specified safety measure when a corresponding risk of collision with such a recognized obstacle is recognized. This can include, for example, issuing a warning as well as intervention in the longitudinal and/or lateral guidance of the motor vehicle.
- Such front collision assistance systems are known, for example, under the designations “Front Assist” or “Emergency Stop Assistant”.
- the environment sensor system can in particular be or include a radar device, a lidar device and/or a camera.
- the environmental data can be or include, in particular, radar data, lidar data and/or camera images.
- swarm data are automatically recorded.
- a first drivable path and a second drivable path are determined from this recorded swarm data.
- These passable paths can, for example, be specified directly by the swarm data, ie they can be taken from the swarm data.
- the first passable path and the second passable path can be calculated, for example, using the swarm data.
- the first drivable path runs in the direction of travel of the motor vehicle in a lane currently traveled by the motor vehicle, which can also be referred to here as the ego lane.
- the second drivable path runs in a neighboring lane adjacent to this ego lane.
- the lane used by the motor vehicle and the adjacent lane can be intended for opposite directions of travel or for the same direction of travel.
- the swarm data can be recorded by the respective motor vehicle, in particular its front collision assistance system. This can mean or include, for example, that the swarm data is transmitted via an X2Car data connection, a mobile phone connection or the like by the motor vehicle or its front collision assistance system, for example from swarm vehicles or from a server device external to the vehicle, for example a backend server, a cloud server, a data center or the like , to be retrieved.
- the swarm data may have been recorded by one or more swarm vehicles when they previously traveled in the driver's lane and the neighboring lane.
- the swarm data can, for example, include or indicate at least one trajectory and/or position data of the respective swarm vehicle along the respective lane or a respective section of the lane. These can be specified, for example, in a global coordinate system and/or relative to respective local features, such as a road marking, a lane boundary, a traffic sign, other road equipment and/or other objects.
- the swarm data can also
- first drivable path and/or the second drivable path can be synthesized, that is to say, for example, based on multiple trajectories or sets of position data piecewise composed or calculated by averaging multiple trajectories.
- the first passable path can also be referred to here as the first swarm path and the second passable path as the second swarm path.
- a swarm vehicle can be an external vehicle that is different from the motor vehicle and is equipped with a sensor system in order to record the swarm data or the sensor data on which it is based.
- the swarm data can have been recorded by a fleet, ie a large number of such swarm vehicles.
- the respective motor vehicle itself can function as a swarm vehicle, for example if it has traveled at least one of the lanes at an earlier point in time and has recorded corresponding swarm data or sensor data on which this is based.
- the corresponding data can be sent from the swarm vehicles to other vehicles, a traffic control infrastructure and/or the mentioned vehicle-external server device, for example.
- the latter can in particular be set up to aggregate data recorded by different swarm vehicles and to make them available in the form of swarm data.
- a distance and/or a change in distance between the first passable path and the second passable path is determined on the basis of the swarm data. If the distance and/or the change in the distance, for example over a predefined distance, is less than a predefined distance threshold value, a triggering sensitivity for the front collision assistance system is automatically reduced in a predefined manner in a further method step of the method according to the invention. This can mean in particular that with a correspondingly reduced triggering sensitivity, the front collision assistance system only reacts, for example, when the distance from the motor vehicle to a detected obstacle is smaller, ie it initiates or executes at least one predetermined safety measure.
- the distance threshold value can, for example, be a fixed value for the distance and/or specify or define a maximum permissible change in the distance.
- the present invention is based on the knowledge that there are always situations in which obstacles, in particular stationary obstacles such as parked vehicles, are present in the ego lane and have to be avoided. This can be cumulative in certain locations, such as on certain sections of a street in a Residential area or the like occur. In this way, avoiding such obstacles, in particular stationary obstacles, at the respective point is also represented in the swarm data, in particular in the course of the first swarm path. Driving around a stationary obstacle in this way typically means that the first swarm path gets closer to the middle of the neighboring lane or runs closer to the middle of the neighboring lane than would be expected or desired without an obstacle in the ego lane. However, such obstacles are often not unexpected, since they can usually, i.e.
- triggering the front collision assistance system as early as possible would often be felt by the driver of the motor vehicle as unnecessary and annoying or as a false triggering, or false triggering can occur when a maneuver to avoid of the obstacle has already been initiated or the motor vehicle would be guided relatively close to the obstacle along its current trajectory.
- the convenience of use of the front collision assistance system or of the motor vehicle can thus be increased.
- safety is maintained because the triggering sensitivity is only reduced and the front collision assistance system is not completely deactivated.
- the present invention can thus even contribute to improved safety, since the acceptance of the front collision assistance system can be improved, which in turn can lead to it being used more frequently or with a greater probability.
- the swarm data or the course of the first swarm path can be automatically analyzed or evaluated to determine whether it is consistent with a driver's planned avoidance of an obstacle, in particular a stationary one, at the side of the road is.
- a planned detour can typically lead to a smoother or flatter course, that is to say less sharp or short-term changes in direction or steering interventions, than, for example, an unplanned one Emergency evasive maneuvers to avoid a collision with a sudden obstacle.
- the triggering sensitivity can be automatically increased again, for example set to a predefined standard value or a manually set user value.
- the present invention can therefore also provide for a correspondingly dynamic, situation-dependent adjustment of the triggering sensitivity when a specific standard or user value for the triggering sensitivity is specified or set for other situations.
- the automatic reduction of the triggering sensitivity can be maintained, for example, for a specified period of time or for a specified distance or for example until the distance or the change in distance has again reached or exceeded the specified distance threshold value.
- the triggering sensitivity can automatically be reset to the previous value or to the specified, in particular larger, standard or user value.
- one or more further or other conditions can be specified.
- the triggering sensitivity can be increased again or set to the standard or user value when the motor vehicle changes lanes or the road, ie, for example, turns or the like, and thus enters a new traffic situation.
- the current position of the motor vehicle can be determined or monitored, for example by means of a navigation satellite system and/or by comparing features detected by means of the environmental sensors of the motor vehicle with corresponding features specified in the swarm data or a given map.
- At least one predetermined criterion is used to determine whether the course of the first drivable path is consistent with driving around a stationary obstacle at the edge of the vehicle traffic lane is. Only if this is the case is the trigger sensitivity automatically reduced as described.
- the specified criterion can be, for example, a distance of the first swarm path from an outer lane edge of the ego lane, an angle of the first swarm path to a lane boundary, a consistency or variance of individual trajectories of the swarm vehicles with each other and/or with the first passable path, especially if this was generated by averaging or combining several such individual trajectories, and/or the like.
- the individual trajectories deviate from one another and/or from the first swarm path, for example a variance above a predetermined threshold value, it can be assumed that frequently changing situations or circumstances are present at the respective location. Reducing the triggering sensitivity of the front collision assistance system can then be dispensed with. In this way, a reduction in safety or ease of use in situations or areas in which obstacles are only irregularly present in the ego lane or in which several significantly different trajectories are possible can be avoided.
- the distance threshold value and/or the reduced triggering sensitivity to be set or the reduction in triggering sensitivity to be carried out in each case is specified by a corresponding multidimensional characteristic diagram.
- the distance and/or the change in distance between the first drivable path and the second drivable path can be taken into account for reducing the triggering sensitivity, but also one or more other variables or parameters. This can enable a particularly precise adjustment of the control of the front collision assistance system for different situations. A further improved safety and a further improved user comfort can thus be achieved.
- the characteristics map has as a dimension at least the speed of the motor vehicle, the road type of the road comprising the lane in which the motor vehicle is driving and the adjacent lane, a local road width and/or a local lane width.
- the map can then specify or specify, for example, that the distance threshold value is greater and/or the triggering sensitivity is reduced the more, the wider the road is according to its road type or the local road or lane width and/or the lower the speed of the motor vehicle.
- the triggering sensitivity is reduced to different extents for the cases in which the neighboring lane is intended for the same direction of travel or for the opposite direction of travel as the lane in which the motor vehicle is driving, all other conditions being the same.
- two different distance threshold values can be specified for these two cases, that is to say the same or opposite driving directions of the driver's lane and the neighboring lane.
- at least two different versions of the characteristics map mentioned elsewhere can be specified for the two possible directions of travel of the adjacent lane relative to the direction of travel of the driver's lane. It can thereby be taken into account, for example, that an approach of the motor vehicle to the center of the adjacent lane associated with driving around an obstacle can be associated with different safety risks when the adjacent lane is traveling in the same direction and in the opposite direction.
- the triggering sensitivity can be reduced more and/or the distance threshold value greater than if the ego lane and the adjacent lane are intended for opposite directions of travel.
- the method is only used, i.e., for example, the reduction in triggering sensitivity is only enabled or considered if the the lane traveled by the motor vehicle in right-hand traffic, viewed in the direction of travel, is on the right or in left-hand traffic, viewed in the direction of travel, on the left of the neighboring lane.
- the—local—curvature of the lane is determined, for example for the area or section for which the navigable paths are also known or have been determined from the swarm data.
- the triggering sensitivity is then only reduced if the curvature is less than a specified maximum curvature, ie less than a specified threshold value of the curvature.
- a specified maximum curvature ie less than a specified threshold value of the curvature.
- This can be implemented, for example, via a separate query or check, or the curvilinearity can be provided or specified or contained as a further dimension in the characteristics map mentioned elsewhere.
- the embodiment of the present invention proposed here makes it possible to take into account that an obstacle in the ego lane is concealed for longer if the curves are correspondingly large due to the course of the road, i.e.
- driver data are recorded which characterize a willingness of the driver of the motor vehicle to drive the motor vehicle manually as appropriate to the situation, ie a willingness of the driver to drive the vehicle.
- the triggering sensitivity is then only reduced if this readiness corresponds to at least a predetermined minimum readiness, that is, for example, is greater than a corresponding predetermined readiness threshold value.
- attention, a direction of view, a grip on the steering wheel, a foot position, a recent history of steering interventions and/or lateral drift of the motor vehicle and/or the like can be recorded or evaluated, for example.
- the driver's willingness to drive the vehicle can be reduced if the driver is distracted or tired and the driver's line of sight is not forward in the direction of travel points, the driver has no or only one hand on the steering wheel or does not grip it securely, for example only with the fingertips or with relatively little force, the driver's legs are crossed and/or the feet are below the pedals or relatively far from the pedals are removed, a lateral drift of the motor vehicle has been corrected by jerky steering interventions and/or the like.
- Corresponding driver data can be recorded, for example, by means of a driver observation camera, by means of a touch sensor in the steering wheel of the motor vehicle and/or the like.
- the reduction in the triggering sensitivity provided according to the invention may only lead to improved user comfort without significantly reducing safety if the driver is attentive and wide enough to be ahead in the ego lane in the direction of travel to recognize lying obstacles in good time and to drive around them safely. If, on the other hand, this is not the case, improved safety can be achieved by triggering the front collision assistance system as early as possible, ie not reducing the triggering sensitivity.
- the front collision assistance system according to the invention has a processor device, ie for example a microchip, microprocessor or microcontroller, and a computer-readable data memory coupled thereto.
- the front collision assistance system according to the invention is set up to carry out the method according to the invention, in particular automatically.
- a corresponding operating or computer program that encodes or implements the method steps, measures or sequences described in connection with the method according to the invention or corresponding control interventions can be stored on the computer-readable data memory.
- This operating or computer program can then be executable by the processor device in order to carry out the corresponding method or to cause or effect its execution.
- the front collision assistance system according to the invention can in particular be the front collision assistance system mentioned in connection with the method according to the invention or correspond to it and accordingly have some or all of the properties and/or features mentioned there.
- the front collision assistance system according to the invention can have an input interface for acquiring the swarm data or also the environmental data.
- the front collision assistance system according to the invention can include, for example, the environmental sensors mentioned, or an interface for direct or indirect connections to the environmental sensors, for example via an on-board network of the respective motor vehicle, and/or the like.
- Another aspect of the present invention is a motor vehicle that has an environment sensor for recording environment data, a communication device for wirelessly receiving swarm data, in particular from other vehicles and/or from a vehicle-external server device, and a front collision assistance system according to the invention.
- the motor vehicle according to the invention can in particular be or correspond to the motor vehicle mentioned in connection with the method according to the invention and/or in connection with the front collision assistance system according to the invention and accordingly have some or all of the properties and/or features mentioned in these connections.
- the motor vehicle according to the invention can also be set up to carry out the method according to the invention, in particular automatically.
- FIG. 1 shows a fragmentary schematic representation of a traffic scene in which there is an obstacle in the path of a motor vehicle that is equipped with a front collision assistance system
- FIG. 2 shows a schematic overview representation to illustrate a method for controlling the front collision assistance system of the motor vehicle.
- Fig. 1 shows a schematic, not to scale overview of a
- a vehicle-external server device 6 is also indicated.
- a motor vehicle 7 is driving in lane 2 in the direction of obstacle 5 .
- the motor vehicle 7 is equipped with an environment sensor system, which can include a camera 8 and a radar device 9 here, for example.
- the camera detection area 10 for the camera 8 and the radar detection area 11 for the radar device 9 are indicated schematically.
- the camera 8 can have an effective range for detecting obstacles of around 50 m to 60 m
- the radar device 9 can have an effective detection range for obstacles of around 200 m, for example.
- the obstacle 5 is still outside of these detection ranges, ie outside of the camera detection area 10 and the radar detection area 11, so that the environmental sensors of the motor vehicle 7 have not yet detected the obstacle 5 themselves.
- the motor vehicle 7 is equipped with a front collision assistance system 12 which includes a processor 13 and a data memory 14 , indicated here schematically.
- a front collision assistance system 12 which includes a processor 13 and a data memory 14 , indicated here schematically.
- environmental data recorded by the environmental sensors driver data that characterizes the driver of motor vehicle 7, vehicle data that characterizes the operation or state of motor vehicle 7, and swarm data 19 (see Fig. 2) that indicate a movement of swarm vehicles along the illustrated section of the Characterize road 1 at earlier points in time are processed.
- the swarm data 19 can be retrieved from the server device 6 by the motor vehicle 7 or the front collision assistance system 12, for example.
- a swarm path 15 along the lane 2 and a neighboring swarm path 16 along the neighboring lane 3 are determined from the collected swarm data 19 .
- the swarm data 19 is retrieved from the server device 6 in the present case, for example by the Front collision assistance system 12. This can be done, for example, before or at the start of the journey or while the motor vehicle 7 is driving. Likewise, while the motor vehicle 7 is driving along the road 1, local data is recorded, for example the aforementioned environmental data, vehicle data, driver data and/or the like.
- the swarm path 15 and the neighboring swarm path 16 are determined from the swarm data 19 . Based on this, a criteria check 20 can then be carried out. One or more predetermined criteria can be evaluated. In particular, it can be determined here whether the directions of travel 4 for the lane 2 and the neighboring lane 3 are the same or opposite to one another. Depending on this, a corresponding map 21 predefined for the respective situation can then be selected or evaluated. The local data recorded in the motor vehicle 7 itself are also taken into account here. The characteristics map 21 can thus specify or output a distance threshold value for the respective situation or the respective conditions.
- a distance evaluation 22 can then be carried out. In this way, it can be determined whether the distance 17 or its change is smaller than the distance threshold value determined using the characteristics map 21 . Corresponding location or position data or information about the swarm path 15 and the neighboring swarm path 16 can be evaluated for this purpose.
- a triggering sensitivity adjustment 23 can then be carried out automatically.
- the triggering sensitivity of the front collision assistance system 12 can be reduced in a predetermined manner if the distance falls below the threshold value.
- a minimum distance value can be specified. This minimum distance value can be approximately 2 m or a typical motor vehicle width, for example. If the result is that the distance 17 falls below this minimum distance value, a reduction in the triggering sensitivity of the front collision assistance system 12 can be provided completely or partially independently of the characteristics map 21 .
- the swarm data 19 can store or specify the historical behavior of other vehicles, namely swarm vehicles, along the road 1 and thus make it possible to determine that the obstacle 5 is likely to be, for example, a parked third-party vehicle that the swarm vehicles are driving around became.
- the swarm data 19 can be specified and taken into account for a larger spatial area, ie beyond the end of the radar detection area 11 remote from the vehicle. This can enable a correspondingly early and consistent adjustment of the triggering sensitivity of the front collision assistance system 12 .
- the examples described show how a method for optimizing a triggering behavior of an assistance system, in particular with regard to an output of warnings and/or interventions in the longitudinal and/or lateral vehicle guidance, can be implemented.
