Abstract:
A driving control apparatus mounted on a present vehicle used for tracking a preceding vehicle includes: control module for controlling the present vehicle to accelerate or decelerate; vehicle detecting module for detecting the preceding vehicle; region detecting module for detecting a lateral region existing on an adjacent lane being adjacent to a present lane where the present vehicle exists, the lateral region being laterally to the present vehicle; and region determining module for determining whether or not the lateral region is an avoidance region that has a predetermined area.The control module performs an avoidance standby operation that allows the present vehicle to accelerate or decelerate based on a result of determining by the region determining module, when the vehicle detecting module detects the preceding vehicle existing on the present lane.
Abstract:
A vehicle control apparatus that for automatic steering control that reduces occupant discomfort and stress is provided. A lane width of a subject lane and a current in-lane ratio are detected. If an off-lane obstacle which may place stress on the occupant is present within a prescribed area, a relative position between each off-lane obstacle and the vehicle is determined. A target in-lane ratio is determined based on the relative position. Specifically, when the off-lane obstacles are present on both the left and right sides of the subject lane, the target in-lane ratio is such that lateral distances to both off-lane obstacles are equal. When the off-lane obstacle is present on only one of either the left or right of the subject lane, the target in-lane ratio is set such that a lateral position away from the off-lane obstacle by a lateral distance set in advance is the target lateral position.
Abstract:
When a travel path is to be generated for a vehicle, road surface lines (white lines, etc.) delimiting the traffic lane of the vehicle, and also external objects in the vehicle environment, are detected and registered as respective obstacles. Specific points are defined at appropriate locations on each obstacle, and the travel path is generated by connecting respective mid-point positions between opposed pairs of specific points, each pair defined on respective ones of an opposed (left-side, right-side) pair of the registered obstacles.
Abstract:
In a vehicle travel assisting device, a vehicle speed, a yaw rate, a traveling lane of an own vehicle, and a position of a leading vehicle are detected. Target travel coordinates of the own vehicle are calculated, based on the traveling lane and the position of the leading vehicle A travel path curvature of a target travel coordinate group is estimated, based on information related to the target travel coordinate group. A steering quantity to be steered in advance by the own vehicle is calculated, based on the currently estimated travel path curvature. A weight for each of the target travel coordinates for estimating the travel path curvature is adjusted based on the vehicle speed, the yaw rate and the previously estimated travel path curvature. Steering control is performed such that the own vehicle travels so as to follow the estimated travel path curvature, based on the calculated steering quantity.
Abstract:
In a vehicle control device, a basic steering amount calculation section calculates a basic steering amount to drive an own vehicle on a basic route along a driving lave. A posture detection section detects a vehicle posture state indicated by a lateral position and an angle of yaw. An offset distance detection section detects an offset distance between the basis route and the lateral position. A correction steering amount calculation section calculates a correction steering amount as a steering control amount to drive the own vehicle along a virtual correction route. The posture of the own vehicle is alien with a predetermined target posture at a predetermined virtual target point by using the virtual correction route. An instruction steering amount calculation section calculates an instruction steering amount on the basis of the basic steering amount and the correction steering amount.

Abstract:
The driving support system detects an object existing around an own vehicle. The driving support system 1 predicts a position of a movement destination of the detected object. The driving support system sets a region having a predetermined width at each of an X coordinate and a Y coordinate as a tracking region to be set for tracking the object, based on an XY coordinate of the position of the predicted movement destination of the object. The driving support system limits the tracking region, based on a tracking exclusion region where objects unsuitable as tracking targets may be detected with high probability. At that time, the driving support system limits the tracking region by excluding the tracking exclusion region from the tracking region.

Abstract:
A travel lane marking probability calculating unit calculates a travel lane marking probability of each of travel lane marking candidates based on a calculation condition. A travel lane marking recognizing unit recognizes, as a travel lane marking, a travel lane marking candidate having a travel lane marking probability that is a threshold value or higher, among the travel lane marking candidates. A lane change detecting unit detects that an own vehicle is in the midst of a lane change. When the own vehicle is in the midst of a lane change, a condition changing unit changes the calculation condition to allow the travel lane marking probability to be more easily increased compared to when the own vehicle is not in the midst of a lane change, or changes the threshold value to be lower than that when the own vehicle is not in the midst of a lane change.
Abstract:
A vehicle driving assistance apparatus mounted in a vehicle. In the apparatus, a drivable route detection unit detects a drivable route, a vehicle state quantity detection unit detects state quantities of the vehicle, and a steering control unit controls steering of the vehicle. Further, in the apparatus, an allowable region estimation unit estimates a driving allowable region on the basis of the detected state quantities and a predetermined allowable range of behavior of the vehicle. A deviation determination unit determines that the vehicle will deviate from the drivable route when a minimum width of an overlap region of the drivable route and the driving allowable region is less than a predetermined threshold. An intervention instruction unit then outputs to the steering control unit an intervention control signal to control steering of the vehicle.
