Patent number: 11776392Abstract: The present invention relates to methods and arrangements for assigning a vehicle to a lane in a road for a vehicle. The proposed solution obtains an estimated pose for the vehicle, projects the pose to nearby lanes, obtains uncertainty values for the pose and lanes, creates a distribution by combining the pose and lane uncertainties, creates a momentary likelihood for the vehicle being in each lane, adjusts the momentary likelihoods with prior values obtained in a previous iteration, and determines the most likely lane.Type: GrantFiled: October 14, 2019Date of Patent: October 3, 2023Assignee: Zenuity ABInventors: Viktor Runemalm, Markus Hammarsten, Jonatan Silvlin, Albin Manhof

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: 10410521Abstract: The present invention relates to a method for determining an evasive path for a host vehicle (10), the method i.a. comprising: establishing (S1) a predicted traffic environment (12) of the host vehicle in a time-lateral position domain, the predicted traffic environment comprising an object prediction representation (16) of a traffic object; determining (S2) a start node (24) for the host vehicle; defining (S3) an end node (26) for the host vehicle; placing (S4) several boundary nodes (28) relative to the object prediction representation; setting (S5) node connections (30, 32, 34a-b, 36a-b, 38, 40, 42) between the start node, the boundary nodes, and the end node; and traversing (S6) the nodes using a graph-search algorithm in order to find a path from the start node to the end time with a lowest cost.Type: GrantFiled: May 7, 2015Date of Patent: September 10, 2019Assignees: Volvo Car Corporation, Volvo Truck CorporationInventors: David Madas, Jonatan Silvlin, Andreas Eidehall, Peter Sundstrom

Patent number: 10108195Abstract: A gap selection method performed by a gap selection system for a vehicle. The vehicle travels on a road having a first lane and a second lane adjacent to the first. The vehicle travels in the first lane, a first surrounding vehicle travels in the second lane, a second surrounding vehicle travels in the second lane ahead of the first surrounding vehicle with a first gap between the first and second surrounding vehicles. The method includes determining a first minimum safety margin between the first surrounding vehicle and the vehicle, determining a second minimum safety margin between the second surrounding vehicle and the vehicle, evaluating the first gap by determining a minimum limit for a longitudinal position of the vehicle, determining a maximum limit for a longitudinal position of the vehicle, and determining a lane change appropriateness value of the first gap utilizing the minimum limit and the maximum limit.Type: GrantFiled: October 6, 2016Date of Patent: October 23, 2018Assignee: Volvo Car CorporationInventors: Jonatan Silvlin, Mattias Erik Brannstrom, Julia Nilsson, Mohammad Ali

Publication number: 20180001927Abstract: Disclosed herein is a method and arrangement for safe limiting of torque overlay intervention in a power assisted steering system of a road vehicle having an autonomous steering function arranged to selectively apply a steering wheel overlay torque to a normal steering assistance torque. A wheel self-aligning torque (ƒR) of the road vehicle is modelled for a current vehicle velocity (?) and pinion angle (?w). A steering wheel overlay torque request (?R) is received. Based on the received steering wheel overlay torque request (?R) is provided a steering wheel overlay torque (?A) in hands-off applications limited to a safe set interval that is symmetrical around the modeled wheel self-aligning torque (ƒR).Type: ApplicationFiled: June 27, 2017Publication date: January 4, 2018Applicant: VOLVO CAR CORPORATIONInventors: Mats HOWING, Lars Johannesson MARDH, Malin HAGLUND, Jonatan SILVLIN

Patent number: 9764735Abstract: A method is disclosed for suppressing or deactivating a lane keeping assist (LKA) system in a host vehicle. The method may include retrieving environmental data from a data gathering system, determining a current lane width based on the environmental data retrieved from the data gathering system, and comparing the current lane width with a pre-set lane width. The method may also include determining that the current lane width is smaller than the pre-set lane width, detecting the presence of an obstacle on the traveling path which obstacle will be passed by the host vehicle or which obstacle will pass the host vehicle within a pre-determined time period, and deactivating or suppressing the lane keeping assist (LKA) system.Type: GrantFiled: May 19, 2015Date of Patent: September 19, 2017Assignee: Volvo Car CorporationInventor: Jonatan Silvlin

Publication number: 20160339910Abstract: A method performed by an evasive maneuver system for providing a driver behavior adapted evasive maneuver to a vehicle at risk of an impending or probable collision. The evasive maneuver system detects a driving environment, determines that the vehicle is at risk of colliding with an obstacle, determines a drivable zone considered safe driving for the vehicle, detects a driver initiated collision avoidance maneuver, and intervenes in control of the vehicle, such that the vehicle is maintained within the drivable zone.Type: ApplicationFiled: May 10, 2016Publication date: November 24, 2016Inventors: Mats JONASSON, Derong YANG, Jonatan SILVLIN
