    Abstract: A system and method for providing target selection and threat assessment for vehicle collision avoidance purposes that employ probability analysis of radar scan returns. The system determines a travel path of a host vehicle and provides a radar signal transmitted from a sensor on the host vehicle. The system receives multiple scan return points from detected objects, processes the scan return points to generate a distribution signal defining a contour of each detected object, and processes the scan return points to provide a position, a translation velocity and an angular velocity of each detected object. The system selects the objects that may enter the travel path of the host vehicle, and makes a threat assessment of those objects by comparing a number of scan return points that indicate that the object may enter the travel path to the number of the scan points that are received for that object.

  • Patent number: 8248295
    Abstract: A pre-crash safety system, which is not influenced by a false recognition that another vehicle is approaching and which causes the vehicle to conduct a safety measure operation when the possibility of a collision exists, is disclosed. The pre-crash safety system includes a collision prediction unit that makes the prediction of a collision between the vehicle and the another vehicle that has entered a monitoring area of the radar device; and a control unit that causes the own-vehicle to conduct the safety measure operation based on a result of the prediction of a collision by the collision prediction unit. The vehicle does not conduct the safety measure operation if, after the another vehicle has entered the monitoring area, a reflection point coordinate which represents a reflection point of a radar wave on the another vehicle is positioned within a predefined direction range when viewed from the vehicle.

  • Patent number: 8244458
    Abstract: A method of quantifying a host vehicle's collision risk with a foreign object includes the steps of collecting and preserving a short-term history of range and azimuth data on the object and identifying leading edges of the foreign object. The leading edges are linked to previous detected leading edges in the short term history storage data to define a trajectory for the object, and to calculate range and azimuth velocities and accelerations of leading edges of the foreign object based on the leading edge trajectory. A collision risk P is then calculated for the foreign object using the range and azimuth velocities and accelerations according to a predetermined formula. If the collision risk P falls below a pre-set value, the methods of the present invention calculate an evasive maneuver for the host vehicle based on a vector sum of high risk leading edge risks and locations.

  • Patent number: 8190330
    Abstract: A system and method for providing steering control for lane changing and lane centering purposes in an autonomous or semi-autonomous vehicle system. A vehicle vision system calculates roadway lane marking information, such as lateral offset, yaw angle and roadway curvature with respect to the vehicle's centered coordinate system. The roadway is then modeled as a second order polynomial equation. The method then predicts roadway lateral position and yaw angle over a pre-defined lane change completion time using a vehicle dynamic model. The method then compares a predicted vehicle path with a desired vehicle path to generate an error value, and calculates a steering angle command to minimize the error value, where the steering angle command is calculated as a function of vehicle lateral position, vehicle lateral speed, vehicle yaw rate and vehicle yaw angle. The steering angle command is then sent to the vehicle steering system.

  • Patent number: 8130138
    Abstract: A ghost target candidate judging device judges that one target of two targets is a candidate for a ghost target where the distances of the two targets from a subject vehicle are equal to each other and where the difference between receiving levels of the two targets is not less than a predetermined value. A running-abreast target judging device judges that one target is the target running abreast of the other target based on changes in an angle difference and in a left-right positional difference between the two targets in accordance with the change in the distances of the two targets from the subject vehicle. The ghost target judging device judges, as the ghost target, a target obtained by removing the running-abreast target data from the candidates for the ghost target. The running-abreast target is prevented from being erroneously recognized as the ghost target while judging which target is the ghost target.

  • Patent number: 8115668
    Abstract: An object candidate position detecting apparatus which detects a position of an object candidate includes a unifying mechanism which unifies a plurality of object candidates detected within a predetermined unified range into a single group. Where the relative positions of the object candidates stored in a unified information storage device changes such that the single group splits into a plurality of groups, a tracking mechanism judges whether any object candidate forming the group before the split continuously remains to be detected in a running lane in which a subject vehicle runs and which is estimated by a running lane estimator. Where any object candidate forming the group before the split is determined as continuously remaining to be detected in the running lane, the tracking mechanism determines that there is continuity between a group after the split including the thus-determined object candidate and the group before the split.
