Definitions
- the invention relates to a method for coupling a trailer coupling attached to a vehicle to a counterpart attached to a trailer.
- Coupling a trailer to a vehicle is usually cumbersome and often problematic.
- conventional vehicles there is no direct view of the trailer coupling attached to the vehicle, which makes it difficult to place the trailer coupling attached to the vehicle near the counterpart attached to the trailer if there are no other assistants present except the driver.
- a driving support system is known from EP 1 249 365 B1 which is intended to remedy the above-mentioned problem.
- the driving support system described there has a display of an image from a reversing camera on a display device, the determined automatically generated auxiliary lines can be overlaid when a given instruction input is received. These auxiliary lines enable the driver to see on the display device how he must steer the vehicle in order to place the trailer coupling attached to the vehicle in the vicinity of the counterpart attached to the trailer.
- the two coupling parts can be brought together with the aid of a threaded support which can lift the trailer-side part of the coupling with the help of a human muscle force and can be lowered onto the vehicle-side part of the coupling.
- the object of the invention is to provide a driver assistance system which enables simple and quick coupling of a trailer to a vehicle without great effort and without the help of other people.
- the driver assistance system for coupling a trailer coupling attached to a vehicle to a counterpart attached to a trailer is characterized in that a Control unit is provided in the vehicle, which controls at least one actuator of a vehicle level control in the presence of a predetermined first condition in such a way that at least the rear part of the vehicle is lowered and / or at least one actuator one when a predetermined second condition is present
- Such a driver assistance system offers the advantage of coupling a trailer to a motor vehicle without great effort.
- Trailers can be, for example, mobile homes or trailers that are used to transport heavy or bulky goods or to transport animals.
- the control device that controls the actuators of the vehicle level control can be combined with a control device that is already in the vehicle or can be implemented as a pure software function in one or more existing control devices (possibly also retrospectively). Since vehicle level regulation is already present in many vehicles, there are no additional costs for these actuators for the driver assistance system according to the invention.
- the actuators of the vehicle level regulation or the vehicle level regulation itself are designed, either the rear part of the vehicle alone or the entire vehicle is lowered or raised when the specified first or second condition is present.
- the reduction or increase takes place by an appropriate amount.
- the vehicle level control system can also be understood as an adjustable air suspension system or a stabilization system for cornering.
- the predefined first condition is met if the distance between the trailer coupling attached to the vehicle and the counterpart attached to the trailer, measured by means of a sensor unit, falls below a predetermined distance value and / or if the trailer coupling attached to the vehicle can be moved together with the counterpart attached to the trailer without maneuvering and / or if a vehicle level control operating element provided for this purpose is actuated.
- the sensor unit is advantageously used for automatic detection of at least the counterpart attached to the trailer for determining its relative position and / or the distance to the vehicle-side coupling.
- Said sensor unit can be based on an optical, ultrasound-based, capacitive, inductive, sensor, contain a combination of these sensors or be based on a RADAR or LIDAR device.
- the determination of the relative position and / or the distance between the two parts of the trailer coupling as the condition for lowering the at least rear vehicle part is advantageous in so far as to ensure with a high probability that the driver intends to couple the trailer.
- the sensor unit also includes the corresponding data evaluation. This can be implemented spatially separated from the sensors in a separate or other existing control unit.
- the coupling parts can, for example, have a special marking.
- the marking can have a special color, texture or wave rip reflection properties.
- a single vehicle level control operating element provided for this purpose can also be actuated to activate the coupling process.
- an already existing button or switch can be assigned a double function. The vehicle is therefore lowered with absolute certainty only if the driver so requests.
- the sensor unit is advantageously designed as a development of an environment-recognizing or image-reproducing assistance system.
- This can advantageously be a reversing camera system and / or a park distance control system (PDC).
- PDC park distance control system
- the image evaluation in an already existing rear-view camera system can be designed, for example, in such a way that in a first step, using an automatic object recognition unit, it detects the trailer coupling attached to the vehicle and the counterpart attached to the trailer and their relative position or only the distance between them automatically calculated from the image data.
- the automatic object recognition unit can be designed in such a way that even when the trailer coupling attached to the vehicle is changed, it is clearly recognized.
- An assistance system that recognizes the environment can also be understood to mean, for example, an optical or RADAR or LIDAR-based lane guidance assistance system or a pre-crash sensor unit.
- the sensor unit is advantageously connected to a display device, which is attached at a location that can be seen from a driver's seat and shows the position of the trailer coupling attached to the vehicle relative to the position of the counterpart attached to the trailer as a geometrically transformed video image or in symbolic form ,
- the driver has the possibility, by means of the display device, of simply placing the trailer coupling attached to the vehicle directly at the counterpart attached to the trailer. If both coupling parts are positioned sufficiently cheaply relative to one another, the driver can be informed automatically that at least the rear part of the vehicle should be lowered automatically by actuating an operating element.
- the control element can also be designed as part of a multifunctional control element or a speech or gesture recognition.
- the display device can be designed as a head-up display.
- the representation can either be a symbolic representation of the two coupling parts and / or a representation of a geometrically transformed camera image. A geometric transformation of the image can be understood as a virtual change of the camera perspective and / or electronic equalization and / or an enlargement or deformation of certain image areas.
- the representation can also be such that it gives the driver a three-dimensional impression of the scene.
- maneuvering lines and / or auxiliary symbols and / or a soft key are shown as vehicle level control operating elements on the display device.
- the vehicle level regulation indicator appears on the display device .
- control element as soft key. This informs the driver that he should now initiate or confirm at least the lowering of the rear part of his vehicle by actuating said control element in order to place the trailer coupling attached to the vehicle under the counterpart attached to the trailer.
- Symbols can represent at least one recommended steering direction for bringing the two coupling parts together and / or a numerical display of the distance between the two coupling parts. If, for example, the sensor unit automatically detects the trailer coupling attached to the vehicle and the counterpart attached to the trailer, the relative position of the two components (trailer coupling and counterpart) can be shown schematically on the display device, which should make it easier for the driver to attach the trailer to the vehicle Place the towbar as conveniently and precisely as possible at or below the trailer's counterpart. Shunting symbols can also be lines that are shown, for example, as the optimally calculated driving line and symbolically represented recommended steering processes.
- the control unit advantageously controls a steering system and / or a drive unit and / or a brake unit of the vehicle in such a way that the steering system and / or a drive unit and / or a brake unit of the vehicle controls the position of the trailer coupling attached to the trailer, as determined by the sensor unit Trailer coupling attached to the vehicle under that on the trailer attached counterpart is placed.
- the control unit advantageously controls a steering system and / or a drive unit and / or a brake unit of the vehicle in such a way that the steering system and / or a drive unit and / or a brake unit of the vehicle controls the position of the trailer coupling attached to the trailer, as determined by the sensor unit Trailer coupling attached to the vehicle under that on the trailer attached counterpart is placed.
- it can make sense to have the automatic execution of the described automatic actions confirmed, for example in several steps, for example by actuating an operating element. It is therefore possible to place the trailer coupling attached to the vehicle partially or fully automatically directly under the counterpart attached to the trailer.
- the predetermined second condition is advantageously present when the trailer coupling present on the vehicle, which is detected by means of the sensor unit, is placed under a counterpart present on the trailer and / or when a vehicle leveling control element is actuated. This eliminates the need to manually lower the trailer clutch onto the vehicle clutch, as is currently common.
- the vehicle level control operating element for lifting can be the same operating element as for lowering.
- the rear part of the vehicle is raised such that the counterpart attached to the trailer is such is also raised that a device that supports the trailer when parked is automatically folded.
- the supporting device can be equipped, for example, with a spring which is in a tensioned position when it supports the trailer. If the weight of the trailer is shifted so that there is no longer any weight on the supporting device, the spring contracts and the supporting device is automatically folded up.
- Fig. 1 shows a vehicle with a trailer coupling attached to the vehicle and a trailer with a counterpart attached to the trailer and
- Fig. 2 shows an embodiment of the driver assistance system according to the invention.
- FIG. 1 shows a vehicle 1 on which a reversing camera 5 as an optical sensor, an ultrasonic sensor 6 and a trailer coupling 3 are attached.
