Abstract

The present invention relates to a method for assisting a driver of a vehicle during the process of coupling a vehicle with a trailer parked parallel to a roadway, the method comprising the step of receiving ambient environment data from one or more ambient environment sensors. Additionally, the method comprises the step of detecting a trailer parked parallel to the roadway using the ambient environment data. Furthermore, the method comprises the step of determining one or more coupling locations describing possible positions of a vehicle for coupling a trailer parked parallel to the roadway. Finally, the method comprises the step of submitting one or more coupling location proposals to the driver, wherein the coupling location proposals are based on one or more coupling locations. In the method, an open space representing an area in front of the trailer in the towing direction is also determined using the ambient environment data. Additionally, the open space is characterized according to the length of the open space determined in the towing direction of the trailer. Furthermore, one or more coupling locations are determined according to the characterized length of the open space.

Description

Method, computing device, and vehicle support system for supporting the process of combining with a trailer The present invention relates to a method for assisting a vehicle driver during the process of combining a vehicle with a trailer parked parallel to a roadway. Additionally, the present invention relates to a vehicle assistance system for assisting a vehicle driver during the process of combining a vehicle with a trailer parked parallel to a roadway. Finally, the present invention also relates to a computing device for a vehicle assistance system. Methods and systems for assisting a vehicle driver during the coupling process in which a trailer is attached to a vehicle have long been known. Such systems are often referred to as trailer coupling aids. In this case, the trailer coupling is mostly detected by the vehicle's existing sensor systems, such as ultrasonic sensors or cameras. Subsequently, the driver receives assistance when maneuvering the vehicle to a possible coupling position, and as a result, the trailer can then be coupled to the vehicle. Publication DE 10 2009 045 284 A1 relates to a method for assisting a driver of a vehicle during driving maneuvers for coupling an object to be coupled having a coupling point to the hitch of the vehicle, wherein the object to be coupled is fixed and the vehicle moves toward the object to be coupled, wherein the distance and direction of the coupling point to the hitch of the vehicle are first detected by one or more distance sensors and the distance and direction between the coupling point and the hitch are displayed to the driver. Publication DE 10 2010 004 920 A1 relates to an apparatus for supporting the coupling of a trailer to a trailer coupling of a vehicle and a method for coupling a trailer to a vehicle. In this case, an apparatus is provided for determining the relative position of the trailer coupling of a trailer to the trailer coupling of a vehicle and for controlling the relative movement of the trailer coupling of a vehicle to the vehicle and/or the movement of the vehicle based on the relative position determined by a sensor method. Publication DE 10 2018 202 613 A1 relates to a method for supporting the coupling process of a vehicle to a trailer, wherein the position of a trailer-side coupling element is recognized using a trailer coupling assist device, and based on this, the vehicle is steered at least partially autonomously to a target position where the vehicle’s trailer coupling is aligned with a preset coupling position for the trailer-side coupling element. In this case, during the steering process, the rear monitoring area of the vehicle is monitored using a parking-in assist device. At this time, when the trailer coupling assist device is deactivated, the parking-in assist device operates in standard mode. Additionally, when the trailer coupling assist device is activated, the parking-in assist device operates in coupling mode, in which, unlike in standard mode, a relevant obstacle warning in the rear area is output using the parking-in assist device. The objective of the present invention is to provide a solution for how a vehicle driver can receive support beyond conventional technology during the process of coupling with a trailer. The above problem is solved by a method having features according to independent claims in accordance with the present invention, by a computing device, and by a vehicle support system. Preferred improvements of the present invention are specified in dependent claims. A method according to the present invention for assisting a driver of a vehicle during the process of coupling a trailer parked parallel to a roadway and a vehicle comprises the step of receiving ambient environment data from one or more ambient environment sensors. Additionally, the method comprises the step of detecting a trailer parked parallel to a roadway using the ambient environment data. Furthermore, the method comprises the step of determining one or more coupling locations describing possible positions of a vehicle for coupling a trailer parked parallel to a roadway. Finally, the method comprises the step of submitting one or more coupling location proposals to the driver, wherein the coupling location proposals are based on one or more coupling locations. In this method, an open space representing an area in front of the trailer in the towing direction is also determined using the ambient environment data. Additionally, the open space is characterized according to the length of the open space determined in the towing direction of the trailer. Furthermore, one or more coupling locations are determined according to the characterized length of the open space. The vehicle can be designed, for example, as a passenger car. Additionally, the vehicle may be a truck, a commercial vehicle, a mobile home, etc. The trailer can be designed, for example, as a simple passenger car trailer equipped with an overrun brake as well as a self-op
