摘要： A reversing assistant system for a vehicle comprising a first path memory for storing a continuously recorded current forward segment, and a second path memory for storing a recorded preceding forward segment. The system is configured to transfer the content of the first path memory to the second path memory when the vehicle resumes forward motion after reversing, and it further comprises a path merger observer configured to repeatedly assess whether the current forward segment is mergeable with the preceding forward segment and, if so, to trigger a path merging operation. The system further comprises a path merger configured to execute a path merging operation and to substitute its output into the first path memory and a drive assistance unit configured to determine drive actions causing the vehicle to reverse along a recorded forward segment or a merged segment.

摘要： A maneuvering assistant system for a vehicle combination comprising an interface configured to receive measurements from a camera, processing circuitry implementing a Kalman filter configured to observe an articulation angle of the vehicle combination on the basis of the measurements from the camera, a signal analyzer configured to repeatedly estimate a signal noise of the camera measurement and to adjust the Kalman filter on the basis of statistics derived from the estimated signal noise, and an assistance unit configured to receive an estimate of the articulation angle from the Kalman filter and provide drive actions based on the estimate.

摘要： The invention relates to a method for guiding a vehicle (1) during reversing along a desired travelling path (TP), wherein the guiding is based on a lateral offset (y) between a preview point (P) located at a preview distance (Pd) behind the vehicle (1) and the desired travelling path (TP), the method comprising: determining (S1) a curvature of the desired travelling path (TP) behind the vehicle (1); adaptively adjusting (S2) the preview distance (Pd) in dependence on the determined curvature, thereby adaptively adjusting the preview point (P); and guiding (S3) the vehicle (1) along the desired travelling path (TP) by use of the lateral offset (y) between the adjusted preview point (P) and the desired travelling path (TP). The present invention further relates to a control unit (100), to a vehicle (1), to a computer program and to a computer readable medium.
