Definitions
- the present invention relates to a method for avoiding a collision of a vehicle with an object.
- the present invention also relates to a control device which is set up to carry out such a method, and to a vehicle with such a control device.
- the present invention relates to a method for avoiding a collision of a vehicle with a potential collision object.
- the vehicle can in principle be any non-rail vehicle.
- the vehicle can be designed as a vehicle that can be operated at least predominantly away from the roads or as a so-called “off-highway” vehicle or as a road vehicle. It can also be an articulated vehicle or an articulated vehicle.
- the vehicle may have a trailer.
- such a vehicle with a trailer can be designed as a vehicle combination, truck or articulated truck.
- the vehicle can be, for example, an agricultural machine with a trailer.
- the vehicle can be a dump truck, a tractor, a truck, a bus or a passenger car.
- the potential collision object can in principle be any object that can be located in the vicinity of the vehicle, and which is with it the vehicle may collide, that is, collisions.
- the potential collision object can be, for example, another vehicle, a person or an object.
- the vehicle In the event of a potential collision with the vehicle, the vehicle, the person or the object can itself be damaged and / or cause damage to the vehicle.
- the collision object and the vehicle In the event of a potential collision, the collision object and the vehicle can move towards one another and meet.
- the potential collision object can also be immobile, in which case the vehicle then encounters the immovable potential collision object.
- the vehicle can also be motionless, in which case the potential collision object then encounters the motionless vehicle. In other words, there is a risk of a collision when the relative distance between the potential collision object and the vehicle decreases to such an extent that it approaches zero.
- the method has, as a step, the definition of a safety area around the potential collision object.
- the safety area can be defined as a function of a potential collision object recognized or recorded by the vehicle on the basis of sensors. In other words, the safety area can only be defined when a potential collision object has been detected.
- the potential collision object can be recognized or recorded with a surroundings detection sensor system arranged on the vehicle.
- the safety area can be defined in an environment around the potential collision object.
- the vehicle is outside the safety area of the potential collision object.
- the safety area can define a safe zone in which the collision object can move safely without a current threat of a collision with the vehicle.
- the safety area of the collision object is also located outside a danger area around the vehicle.
- the two areas thus define areas that are spatially separated from one another.
- the safety area of the collision object and the danger area of the vehicle cannot therefore overlap.
- the safety area of the collision object can border the danger area of the vehicle at least in sections.
- Under the Danger area can be understood as an area in which the vehicle can present a current danger to a potential collision object.
- the danger area can be defined as a function of the current position of the vehicle or of vehicle parts, for example a trailer or a work tool, in the vicinity of the vehicle.
- the method has a prediction of a trajectory corridor which the vehicle will sweep along a future trajectory and during a certain period of time.
- Predicting a trajectory corridor can include predicting a future trajectory corridor.
- Predicting the trajectory corridor can also include calculating or mathematically estimating a future trajectory corridor.
- a trajectory corridor can thus be predicted with a certain probability.
- a trajectory corridor can be predicted, for example, based on an extrapolation of a previous trajectory of the vehicle. For example, a higher order polynomial, for example a second or third order polynomial, can jointly describe the previous vehicle trajectory and a section of a future vehicle trajectory.
- the future trajectory corridor can then be determined on the basis of an extrapolated vehicle trajectory.
- the trajectory corridor can be a corridor of a towing curve of the vehicle that the vehicle travels straight ahead and / or traverses while cornering.
- the trajectory corridor can be a space or driving area that the vehicle will occupy dynamically along its future trajectory.
- the trajectory corridor can also be referred to as the towing corridor of the vehicle.
- the trajectory corridor can be limited by a movement curve of a vehicle area on the outside of the bend.
- the vehicle area on the outside of the curve can be, for example, a front area or side area of the vehicle on the outside of the curve.
- the trajectory corridor can also be limited to the inside of the curve by a movement curve of a part of the vehicle on the inside of the curve.
- the vehicle area on the inside of the curve can be, for example, a wheel of the vehicle on the inside of the curve or a trailer wheel on the inside of the curve.
- the time span of the predicted trajectory corridor can have a prediction interval which defines the future time frame in which the trajectory corridor is predicted.
- the period of time can for example be determined as a function of or based on a reaction time of the vehicle to a detected potential collision object, a braking duration of the vehicle to avoid a collision with the potential collision object and / or a current vehicle speed.
- the method has the implementation of a safety measure on the vehicle in order to avoid a collision of the vehicle with the potential collision object.
- the safety measure can be a reaction to a potential collision object detected by the vehicle in order to avoid an impending collision.
- the reaction can be a reaction actively carried out by the vehicle itself or by an operator of the vehicle, for example an intervention in the dynamics of the vehicle.
- the safety measure can thus be an active change in the movement behavior of the vehicle or the automatic selection of a new route.
- the reaction can be the output of a warning to warn of the potential collision. The operator of the vehicle can then decide for himself which measure is required to avoid a collision.
- the implementation of the safety measure is based on a geometric comparison of the predicted trajectory corridor or its spatial position with the defined safety area or its spatial position. It may be necessary to carry out the safety measure if the predicted trajectory corridor comes too close to the safety area.
- the geometric comparison can include determining a distance between the safety area and the trajectory corridor.
- the geometrical comparison can comprise a mere determination of the presence of an overlay. In the cases described, safe movement of the potential collision object in its safety area can be impaired or spatially restricted by the current movement behavior of the vehicle.
- Steps of the process can be carried out continuously.
- the steps can be performed in a loop. If the vehicle and / or the potential collision object is in motion, the safety area of the potential collision object can be set continuously at different times and the trajectory corridor can be continuously predicted at these times. Continuously defined safety areas can be continuously compared with the continuously predicted trajectories.
- a safe movement space for the at least one object can be maintained, taking into account the movement behavior of the vehicle.
- a corridor that the vehicle will traverse in the future is predicted for this.
- a measure is taken to eliminate the impairment.
- a vehicle can be navigated in such a way that a future risk of collision with potential collision objects is constantly minimized.
- the safety area around the potential collision object is located within a detection area of a surroundings detection sensor system arranged on the vehicle.
- the surroundings detection sensor system can have at least one camera, at least one laser scanner (lidar), at least one radar sensor and / or at least one ultrasonic sensor, with which a potential collision object can be detected individually or in any combination.
- the at least one camera can detect a potential collision object, for example in stereo mode or mono mode.
- the detection area can thus cover an area around the vehicle depending on a detection include the range of the surroundings detection sensor system, in which a potential collision object can be reliably detected by the surroundings detection sensor system.
- the step of determining the safety area around the potential collision object is carried out taking into account a shading area.
- the shading area can be an area lying within the detection area, which is shaded by the vehicle and cannot be detected by means of the surroundings detection sensors.
- a vehicle part that causes shading can be, for example, a trailer or a work tool of the vehicle. If the surroundings detection sensor system has at least two different sensors, which can be arranged at different positions on the vehicle, that surroundings detection sensor can be selected for object detection which has the largest detection area and / or the smallest current shading area. Depending on the current position of a vehicle part, which can result in different shading areas for the different sensors, that sensor can also be selected for detecting the surroundings whose detection area is currently the least shaded.
- the surroundings detection sensor system has at least two different sensors, which can be arranged at different positions on the vehicle, at least two sensors can also be merged.
- a merged detection area can thus be enlarged in comparison to a single detection area.
- the safety area can thus be enlarged and / or the shading area can be reduced.
- the method can include a detection of a relative position of the potential collision object with respect to the vehicle with the environment detection sensor system.
- the step of determining the safety area is then carried out taking into account the relative position of the potential collision object around the potential collision object.
- the safety area around the potential collision object can thus be defined in an area which does not completely surround the vehicle. Rather, the safety area can be an area that is spanned around the potential collision object. For example, the safety area can extend radially around the po- potential collision object.
- the safety area can be an area which is limited by a partial detection area of the surrounding area detection sensors. For example, the safety area can be limited sectorally based on the vehicle's surroundings detection sensor system by a detection angle area.
- One embodiment of the method has, as a step, predicting at least two trajectory corridors which the vehicle can sweep along at least two future trajectories.
- the at least two future trajectories can be determined based on different future travel routes of the vehicle.
- the various future travel routes can have different routes that can be traveled in the future.
- the at least two future trajectories can for example have a left turn or a left-curved cornering and a right turn or a right-curved cornering along a respective future route.
- One of the at least two future trajectories can, for example, also have straight-ahead travel or a straight route.
- the embodiment can have a selection of one of the at least two predicted trajectory corridors based on a detected vehicle behavior or based on a vehicle operator behavior.
- the applicable or the more likely future trajectory can be determined and selected.
- the safety measure on the vehicle to avoid the collision of the vehicle with the collision object can take place as a function of a geometric comparison of the selected trajectory corridor with the defined safety area.
- the step of predicting the trajectory corridor or the at least two trajectory corridors is carried out based on a sensor system arranged on the vehicle.
- the sensors arranged on the vehicle can be used to determine a current trajectory of the Vehicle be trained.
- the sensor system can be a position and / or direction-determining sensor system for determining the current position of the vehicle or a two-dimensional movement of the vehicle.
- Such a sensor system can, for example, have a steering angle sensor, a yaw rate sensor, an inertial measuring unit (IMU), a satellite positioning system (GNSS), a wheel speed sensor and / or a radar sensor for determining an above-ground speed. If the vehicle is an articulated vehicle, the sensor system can also have an articulation angle sensor.
- the sensor system arranged on the vehicle can alternatively or additionally be designed to determine a state parameter of a drive train of the vehicle.
- the status parameter can for example be a current engine speed, gear ratio or gear output speed.
- a vehicle outline can be taken into account, wherein the vehicle outline can be an area spanned horizontally by the vehicle.
- the vehicle outline can change as a function of vehicle-specific kinematics or a turning behavior.
- a current vehicle outline can also be measured and / or modeled.
- an intervention in the transverse dynamics of the vehicle to avoid a collision of the vehicle with the collision object is carried out as a safety measure.
- an intervention in the longitudinal dynamics of the vehicle can be carried out as a safety measure in order to avoid the collision of the vehicle with the collision object.
- the intervention in the transverse dynamics of the vehicle can include, for example, a change in a driving direction or a change in a steering angle of the vehicle.
- the intervention in the longitudinal dynamics of the vehicle can include, for example, changing the driving speed of the vehicle. This can be the acceleration or deceleration of the vehicle. Braking can be slowing down until the vehicle comes to a standstill. Alternatively or additionally, a gear ratio can also be changed as a safety measure.
- a visual, acoustic or haptic warning of an operator of the vehicle is used as a safety measure and / or the collision object is carried out to avoid the collision of the vehicle with the collision object.
- the operator of the vehicle can be a driver present on the vehicle.
- the operator can also control the vehicle remotely.
- the operator can then choose an alternative route to avoid the collision himself.
- a “bystander” outside the vehicle can also be warned. It is also conceivable that an operator of the vehicle can be warned by haptic feedback from the steering wheel, for example by a citing.
- the geometric comparison of the predicted or selected trajectory corridor with the established security area includes a determination of a distance between them.
- the safety measure can thus be initiated as a function of how close the vehicle will move to the safety area in the observed time span for the trajectory corridor.
- a limit value for a distance between the predicted or selected trajectory corridor and the defined safety area can be set.
- the limit value can be a safety distance between the trajectory corridor and the safety area.
- the determined distance can be the smallest distance between the trajectory corridor and the defined safety area.
- the step of performing the safety measure on the vehicle can also be carried out in order to maintain a current distance between the trajectory corridor and the defined safety area or to increase it again if the specific smallest distance falls below the defined limit value.
- the current distance can be increased again by the safety measure directly, for example by selecting an alternative route or indirectly, for example by means of a warning, as described above.
- the present invention also relates to a control device which is set up to carry out the method according to one of the described embodiments.
- the control device can have various interfaces for receiving and outputting the corresponding signals.
- a specific preparation, for example programming, of the control device for executing the function can be understood.
- the present invention also relates to a vehicle which has such a control device.
- the vehicle can be designed as a vehicle that can be operated off-road.
- the vehicle can also be designed as a vehicle that can be operated autonomously or as a driverless vehicle.
- Figure 1 shows a vehicle with a control device according to an embodiment of the present invention to explain a method for collision avoidance according to an embodiment of the present invention.
- a ring-like safety area is shown which surrounds the potential collision object and encloses the vehicle.
- FIG. 2 shows the vehicle from FIG. 1 to further explain the method for collision avoidance.

- FIG. 1 shows a vehicle 10 with a control device 40 and a potential collision object 20 in the vicinity of the vehicle 10.
- various areas relevant to the method for avoiding a collision of the vehicle 10 with the potential collision object 20 are shown schematically, which will be discussed in more detail below.
- a safety area 22 around the potential collision object 20 is limited, on the one hand, by a detection area 32 of an environment detection sensor system 30 arranged on the vehicle 10.
- the detection area 32 thus represents an outer delimitation of the safety area 22.
- the safety area 22 is delimited by a shading area 34 of the area detection sensor system 30 arranged on the vehicle 10.
- the shading area 34 thus represents an inner delimitation of the safety area 22.
- the surroundings detection sensor system 30 cannot detect a potential collision object 20 which is located in the shading area 34.
- the safety area 22 is also located outside of a danger area 12 around the vehicle 10, in which there is an immediate danger from moving vehicle parts.
- a future trajectory 16 is calculated in advance by extrapolating the trajectory of the vehicle 10 that has already been driven.
- the length of the future trajectory 16 is determined as a function of a journey time and a future vehicle speed.
- a trajectory corridor 14 is then calculated in advance, which the vehicle 10 sweeps along the future trajectory 16.
- a distance 18 between the safety area 22 and the predicted trajectory corridor 14 is calculated. If the distance 18 exceeds a safety distance (not shown) between the safety area 22 and the predicted trajectory corridor 14, a collision is not to be expected. If the distance 18 falls below the safety distance between the safety area 22 and the predicted trajectory corridor 14, the predicted trajectory corridor 14 touches the safety area 22 or the predicted trajectory corridor 14 and the safety area 22 overlap in an overlap area (not shown). In this case a collision is to be expected.
- the situation shown in FIG. 2 differs from the situation shown in FIG. 1 in that the safety area 22 of a collision object 20 does not completely surround the vehicle 10 as shown in FIG. Instead, the safety area 22 is designed as a partial area of the ring-like area defined between the detection area 32 and the shading area 34. Another potential collision object 20 is shown for further clarification.
- a border 23 of the security area 22 can thus have lateral boundaries in addition to the detection area 32 as an outer boundary and the shading area 34 as an inner boundary, based on the position of the potential collision object 20.
- the lateral boundaries are defined by a sectoral area in the detection area 32 in which the potential collision object 20 is located.
- the safety area 22 then has two corresponding areas defined around the two potential collision objects 20 with their borders 23. If there is only one potential collision object 20 in the vehicle environment, the safety area 22 consists of only one area defined in this way.
- a safety measure for avoiding a collision of the vehicle 10 with the collision object 20 then consists in a warning to an operator of the vehicle 10 or in the selection of an alternative trajectory that deviates from the predicted trajectory 16.
- the alternative trajectory has a shorter length or a different course, by a distance between the safety area 22 and a trajectory corridor of the alternative trajectory compared to the distance 18 to enlarge.
- the vehicle 10 is designed as a semitrailer with a towing vehicle and a semitrailer or semitrailer.
- the vehicle 10 turns at an intersection 11.
- the vehicle 10 sweeps over different trajectory corridors 14 as a function of a turn to the left shown in FIG. 3 or a turn to the right shown in FIG. 4, the difference being not merely a symmetrical reflection, but the geometric shape.
- a potential collision object 20 is shown in FIGS. 3 and 4.
- a safety area 22 is schematically shown around the potential collision object 20, which is formed in accordance with the above explanations in connection with FIGS. 1 and 2.
- a distance 18 is present between a trajectory corridor 14 when the vehicle 10 turns left and the safety area 22 around the potential collision object 20 at a certain point in time, which does not fall below a safety distance (not shown).
- a safety measure to avoid a collision between the vehicle 10 and the potential collision object 20 located at the intersection 11 is therefore not required while the vehicle 10 is driving in the situation shown.
- a trajectory corridor 14 when the vehicle 10 turns right and the safety area 22 around the potential collision object 20 overlap at a specific point in time.
- a safety measure to avoid a collision between the vehicle 10 and the potential collision object 20 located at the intersection 11 is therefore required while the vehicle 10 is in motion. In one case, this consists of a warning to the operator of vehicle 10 before vehicle 10 has entered intersection 11.
- FIG. 5 shows a diagram with steps of a method for avoiding a collision between a vehicle 10 and a potential collision object 20.
- a first step U1 one or more potential collision objects 20 are detected with the surroundings detection sensor system 30 arranged on the vehicle 10 and the relative ve position of the potential collision object 20 to the vehicle 1 0 is determined.
- the at least one potential collision object 20 is detected using a number of surrounding area detection sensors. Based on the potential collision object 20 detected redundantly in this way, the signals detected by the surroundings detection sensors are merged in a further step U2.
- the merging of the detected signals includes a superimposition or selection of detection areas and shading areas of the surroundings detection sensors of the surroundings detection sensor system 30 for detecting the potential collision object 20.
- step S1 the safety area 22 around the at least one detected potential collision object 20 is determined as described above.
- a single trajectory corridor 14 is predicted in step S2.
- step A the minimum distance 18 between the safety area 22 established in step S1 and the trajectory corridor 14 predicted in step S2 is calculated.
- a distance comparison V it is considered whether the calculated distance 18 is smaller than a permitted safety distance as a comparison threshold. If this is the case, one of the previously described safety measures for avoiding a vehicle-object collision is carried out in step S3. If during the distance comparison V it is found that the calculated distance 18 is greater than or equal to the Is the permitted safety distance, none of the safety measures described to avoid a vehicle-object collision are carried out in the subsequent step S3 '.
- step S3 or S3 ' the procedural steps described are carried out again, starting with steps T1 and U1.
