20090192710 | METHOD AND SYSTEM FOR COLLISION COURSE PREDICTION AND COLLISION AVOIDANCE AND MITIGATION - A system for collision course prediction includes a host vehicle sensor system detecting information relating to a target object including a position and a velocity relative to the host vehicle; a time-to-collision estimator control block calculating an estimated time-to-collision based on a longitudinal distance, longitudinal velocity and longitudinal acceleration of the target object relative to the host vehicle; a lateral distance estimator control block, which estimates the lateral distance between the centers of the host vehicle and target object at the estimated time-to-collision; and a collision course condition determination unit determining, at a determination instant prior to the estimated time-to-collision, a probability that the host vehicle will collide with the target object dependent at least in part upon whether the lateral distance is within a first interval, the first interval based on at least a lateral width of the host vehicle and a lateral width of the target object. | 07-30-2009 |
20110071731 | METHOD AND SYSTEM FOR COLLISION AVOIDANCE - A method for collision avoidance for a host vehicle includes the following steps; receiving input data relating to a set of objects external to the host vehicle, wherein an object position (r,Φ), and an object velocity ({dot over (r)}) are associated with each object by a sensor system arranged on the host vehicle, then estimating future trajectories of each external object, while considering influence by the future trajectories of the other external objects. | 03-24-2011 |

20100076685 | SYSTEM AND METHOD FOR ASSESSING VEHICLE PATHS IN A ROAD ENVIRONMENT - A method and system for assessing vehicle paths in a road environment including a vehicle and external objects includes: determining a position and a dynamic state of the host vehicle and of each of the external objects; generating a plurality of paths that may be followed by the vehicle as it moves toward the external objects; and evaluating a cost associated with each of the paths, the cost based on a lateral acceleration experienced by the vehicle. Each path is made up of path segments, including: an initial path segment corresponding to the vehicle continuing along a selected route without consideration of the external objects, and a maneuver pair for each external object, each maneuver pair including a path segment passing to the left of the external object and a path segment passing to the right of the external object. | 03-25-2010 |
20110178710 | COLLISION MITIGATION SYSTEM AND METHOD FOR BRAKING A VEHICLE - A collision mitigation system for a vehicle may include a forward sensing system and at least one controller in communication with the forward sensing system. The forward sensing system may be configured to detect objects in front of the vehicle. The at least one controller may be configured to determine whether the vehicle can be steered into a path along side of the vehicle to avoid a collision with detected objects in front of the vehicle and to issue a command to brake the vehicle if the vehicle cannot be steered into the path along side of the vehicle. | 07-21-2011 |
20110288774 | FORWARD COLLISION RISK REDUCTION - A method for determining a safety zone of a foreign object for a forward collision risk reduction system. The method may include determining the type of the foreign object; setting the safety zone to a predetermined value corresponding to the type of the foreign object; determining the traffic behavior of the foreign object; determining if the traffic behavior corresponds to a species of a predetermined group of traffic behaviors; and if the traffic behavior corresponds to a species of a predetermined group of traffic behaviors, modifying the safety zone in accordance with a predetermined species function corresponding to the species. | 11-24-2011 |

20140207364 | METHOD AND ARRANGEMENT FOR DETERMINING A TRAJECTORY - 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. | 07-24-2014 |
