A method for assisting the reversal of an articulated vehicle includes recording a predefined number of positions for a first articulated vehicle for a specified path, recording the articulation angle of each articulation joint of the articulated vehicle at the predefined number of positions, recording the heading for the first articulated vehicle at the predefined number of positions, saving the recorded values for the specified path in a memory, calculating the swept area of the first vehicle for the specified path by using the recorded values and size information of the articulated vehicle, and using the swept area to control the steering of the articulated vehicle when reversing the articulated vehicle along the specified path, such that the articulated vehicle does not extend outwards of the swept area during the reversal. The area covered by the articulated vehicle when traveling forwards can be used to control the steering of the vehicle when reversing along the same path, such that the articulated vehicle substantially does not extend outward the swept area when reversing. In this way, an assisted reversing functionality can be used, which allows for a faster and more efficient reversing of the articulated vehicle, and at the same time allows for an improved comfort for the driver.
