20140292502 | DRIVING SUPPORT SYSTEM - A driving support system detects a target area ahead of the vehicle, a position or a moving direction, etc. of an object such as a pedestrian or another vehicle by using a camera or radar, as well as determines a probability of collision between the own vehicle and the object based on the position, etc. of the object, and performs a driving support for avoiding the collision when the probability of the collision is high. Further, a sensitivity of determination is set high when the object remains in the target area, or when the object is moving towards the target area, while the sensitivity is set low when the object is not present in the target area, or the object is moving away from the target area. | 10-02-2014 |
20140297134 | ON-BOARD APPARATUS - An on-board apparatus includes a measuring unit, a filtering unit, a predicting unit, an executing unit, a detecting unit, and an adjusting unit. The measuring unit periodically measures a state of an own vehicle. The filtering unit performs a low-pass filter process on measurement results from the measuring unit. The predicting unit predicts behavior of the own vehicle based on the measurement results on which the low-pass filter process has been performed. The executing unit performs processes based on the behavior of the own vehicle predicted by the predicting unit. The detecting unit detects a traveling environment of the own vehicle. The adjusting unit adjusts a time constant for the low-pass filter process based on the traveling environment detected by the detecting unit. | 10-02-2014 |
20140297170 | DRIVING SUPPORT SYSTEM - A driving support system detects a position of an object ahead of an own vehicle as well as predicts a course of the own vehicle. Then, a collision probability between the own vehicle and the object is determined based on the predicted course and the position of the object, and performs the driving support for avoiding collision when the collision probability is high. Further, the driving support to system measures a curvature of a target road, and when a change in the curvature is small and an accurate course prediction is possible, a determination sensitivity of the collision probability is set high so that the driving support is easy to start, otherwise the determination sensitivity of the collision probability is set low so that the driving support is difficult to start. | 10-02-2014 |
20150063648 | METHOD AND APPARATUS FOR RECOGNIZING ROAD SHAPE - A method and an apparatus are provided to recognize a shape of a road on which a vehicle is traveling. Road edge shapes on a left side and a right side of the vehicle are recognized, from positions of roadside objects detected based on detection information from an on-board radar. Lane shapes that are shapes of lane boundary lines on the left side and the right side of the vehicle are recognized, from positions of lane boundary lines detected based on an image captured by an on-board camera. For each of the left side and the right side, such that the recognized road edge shape and the recognized lane shape are compared with each other, and the road shape is identified based on the comparison results. | 03-05-2015 |
20150175166 | COURSE ESTIMATOR - A course estimator has a first estimating means, a second estimating means and a determining means. The first estimating means obtains first information and estimating a first radius of a first forward traveling path on the basis of the obtained first information, the first forward traveling path being a part of a forward traveling path to which a vehicle is going to travel. The second estimating means obtains second information and estimating a second radius of a second forward traveling path on the basis of the obtained second information, the second forward traveling path being a part of the forward traveling path to which a vehicle is going to travel, the second forward traveling path being farther from the vehicle than the first traveling being. The determining means determines whether or not there is a changing point where road shapes change between the first forward traveling path and the second forward traveling path on the basis of comparison of the estimated first radius and the estimated second radius. | 06-25-2015 |
20150175167 | COURSE ESTIMATOR - This disclosure provides as an aspect a course estimator having a curvature radius estimator, a calculator and a determination section. The curvature radius estimator obtains first information on a forward traveling path ahead of a vehicle in a traveling direction of the vehicle at different time points and estimating, on the basis of the first information obtained repeatedly, each curvature radius of the forward traveling path at a respective time. The calculator calculates change information indicating magnitude of time change in curvature radius of the forward traveling path on the basis of the estimated curvature radiuses of the forward traveling paths. The determination section determines whether or not there is a changing point where a road shape of the forward traveling paths changes on the basis of the calculated change information. | 06-25-2015 |
20150197249 | APPARATUS AND COMPUTER PROGRAM FOR CONTROLLING VEHICLE TRACKING TARGET VEHICLE - In an apparatus for controlling a vehicle to track another vehicle, a controller causes the controlled vehicle to track one of other vehicles as a target vehicle if one of the other vehicles meets a target-vehicle selecting condition. The target-vehicle selecting condition is required for selecting one of the other vehicles as the target vehicle. The controller recognizes an environment of a predicted travel road on which the controlled vehicle is predicted to travel using conditions of the predicted travel lane. The controller determines whether the predicted travel road allows lane changes based on the recognized environment of the predicted travel road. The controller adjusts the target-vehicle selecting condition based on a result of the determination. | 07-16-2015 |
20150298692 | VEHICLE DRIVING SUPPORT APPARATUS FOR EXECUTING COLLISION AVOIDANCE OPERATIONS BASED ON POSITION AND MOTION CONDITION OF TARGET OBJECT - A driving support apparatus installed in a host vehicle calculates an overlap ratio relating to a target object positioned ahead of the host vehicle within the same traffic lane, as the ratio of the width of the target object to its lateral distance from a lane marker line of the traffic lane, and also detects the motion condition of the object (i.e., stationary, moving towards, or in the same direction as the host vehicle, or moving laterally with respect to the forward direction of the host vehicle). An amount of compensation for retarding or advancing the commencement of a collision avoidance operation by the driving support apparatus is determined based on the overlap ratio and/or the motion condition of the target object. | 10-22-2015 |
