Patent number: 10435017Abstract: A method is for providing an object prediction representation. In an embodiment, the method includes simulating movement of a host vehicle and an object in a longitudinal-lateral coordinate system based on their initial positions at the starting time and a movement of the host vehicle and determined movement of the object. Points in time when at least one reference point of the host vehicle and an object reference point of a plurality of object reference points have the same longitudinal position are detected. Further, for each detected point in time, an associated lateral position of the object reference point at the detected point in time is detected.Type: GrantFiled: May 7, 2015Date of Patent: October 8, 2019Assignees: VOLVO CAR CORPORATION, VOLVO TRUCK CORPORATIONInventors: David Madas, Jonatan Silvlin, Andreas Eidehall, Peter Sundstrom

Patent number: 9489847Abstract: A method and an arrangement are provided for determining a trajectory for a host vehicle H in order to as smoothly as possible avoid or mitigate a collision. The arrangement may include a processor and at least one of a sensor system or a communication system. The method may include identifying positions of one or more external objects in relation to the host vehicle H within a predefined distance, generating a plurality of trajectories that are valid for enabling the host vehicle H to pass any desired number of external objects, removing any trajectories intersecting with any one of the external objects, estimating lateral position, lateral velocity, lateral acceleration and the lateral jerk that will act on the host vehicle H driving along any one of the trajectories, and selecting the trajectory for which the lateral jerk acting on the host vehicle H is minimized.Type: GrantFiled: January 13, 2014Date of Patent: November 8, 2016Assignee: Volvo Car CorporationInventors: Andreas Eidehall, David Madas
