Patent application number | Description | Published |
20080303696 | Host vehicle moving area acquisition device and acquisition method - A movable area acquisition ECU 1 compares a possible path for a host vehicle and a predicted path of another vehicle in a travel area of the host vehicle with each other to obtain a possibility of collision between the two vehicles, thus computing a degree of danger to the host vehicle. If the degree of danger to the host vehicle exceeds a predetermined threshold, the travel area is extended and then a degree of danger to the host vehicle is computed and acquired. | 12-11-2008 |

20100063735 | METHOD, APPARATUS AND PROGRAM OF PREDICTING OBSTACLE COURSE - A method, an apparatus, and a program of predicting an obstacle course, capable of appropriately predicting a course of an obstacle even under a complicated traffic environment, are provided. For this purpose, the course, which the obstacle may take, is predicted based on the position and the internal state of the obstacle, and at the time of the prediction, a plurality of courses are probabilistically predicted for at least one obstacle. When there are a plurality of obstacles, the course in which different obstacles interfere with each other is obtained from the predicted courses, which a plurality of obstacles may take, and the predictive probability of the course for which the probabilistic prediction is performed from the courses in which they interfere with each other is lowered. Probability of realizing each of a plurality of courses including the course of which predicted probability is lowered is calculated. | 03-11-2010 |
20100106418 | VEHICLE TRAVEL TRACK ESTIMATOR - A vehicle risk level acquiring ECU calculates and acquires a plurality of courses of other vehicles around a driver's own vehicle, and acquires the predicted course of the driver's own vehicle. The vehicle risk level acquiring ECU calculates the collision probability of the driver's own vehicle as collision possibility on the basis of the predicted course of the driver's own vehicle and the plurality of courses of other vehicles. | 04-29-2010 |
20100121576 | HOST-VEHICLE RISK ACQUISITION - A host-vehicle risk acquisition device includes a host-vehicle path acquisition portion that acquires a path of a host-vehicle, and an obstacle path acquisition portion that acquires a plurality of paths of an obstacle existing around the host-vehicle. A collision risk acquisition portion acquires an actual collision risk, which is a collision risk between the host-vehicle and the obstacle when the host-vehicle is in a travel state based on the path of the host-vehicle and the plurality of paths of the obstacle. An offset risk acquisition portion acquires an offset risk, which is a collision risk between the host-vehicle and the obstacle in an offset travel state, which is offset from the travel state of the host-vehicle. | 05-13-2010 |
20100318240 | COURSE EVALUATION APPARATUS AND COURSE EVALUATION METHOD - A course evaluation that evaluates a course of a mobile unit includes: generating a predetermined first course of the mobile unit; generating, for the first course, a second course for which a controlled amount of the mobile unit after a predetermined driving condition is satisfied is increased as compared with a controlled amount of the mobile unit on the first course; estimating another object course, which is a course of another object; determining whether the second course interferes with the other object course; and evaluating a degree of safety of the first course on the basis of a result of determination as to whether the second course interferes with the other object course. | 12-16-2010 |
20110054793 | ENVIRONMENT PREDICTION DEVICE - An environment prediction device can acquire sufficient information regarding the behavior of an object in the vicinity of a host-vehicle for appropriate traveling assistance. An environment prediction device | 03-03-2011 |
20130261952 | COLLISION DETERMINATION DEVICE - A collision determination device determines the possibility of collision between a host vehicle and the other object on the basis of a shortest arrival time calculated by a shortest arrival time calculation unit and a passage time at each point of the host vehicle acquired by a vehicle route candidate acquisition unit. In this way, even if a locus to be taken by the other object is not generated, the shortest arrival time at which the other object can arrive at each point of the route candidate of the host vehicle with a predetermined first displacement is calculated, thereby determining the possibility of collision between the host vehicle and the other object. Therefore, it is possible to reduce a computational load for determining collision and to accurately determine collision between the host vehicle and the other object. | 10-03-2013 |
20130289868 | HOST-VEHICLE RISK ACQUISITION DEVICE AND METHOD - A host-vehicle risk acquisition device includes a host-vehicle path acquisition portion that acquires a path of a host-vehicle, and an obstacle path acquisition portion that acquires a plurality of paths of an obstacle existing around the host-vehicle. A collision risk acquisition portion acquires an actual collision risk, which is a collision risk between the host-vehicle and the obstacle when the host-vehicle is in a travel state based on the path of the host-vehicle and the plurality of paths of the obstacle. An offset risk acquisition portion acquires an offset risk, which is a collision risk between the host-vehicle and the obstacle in an offset travel state, which is offset from the travel state of the host-vehicle. | 10-31-2013 |
