Abstract:
A driving intention estimation, driver assistance and vehicle with the driver assistance for providing a stable estimation of a driver's driving intention even if detection of a relationship between an own vehicle and lane markers is lost. A plurality of imaginary drivers of a first type and a second type, each being given a respective driving intention, are provided. When detection of lane markers is reliably kept, a driving intention by a real driver is estimated based on a comparison between an operation of the real driver to operations of the imaginary drivers of the first type that are calculated based on the relative positional relationship of the own vehicle to the detected lane marker. When the detection of lane markers is lost, operations of the plurality of imaginary drivers are calculated based on the relative positional relationship of the own vehicle to a preceding vehicle. In response to the status of detection of the lane marker, either the imaginary drivers of the first type or the second type are selected.
Abstract:
An imaging system for a vehicle includes an imaging sensor and a control. The imaging sensor is operable to capture an image of a scene occurring exteriorly of the vehicle. The control is responsive to the imaging sensor. The imaging system may be associated with a side object detection system, a lane change assist system, a lane departure warning system, a monitoring system, a passive steering system and/or the like. The control may be operable to process a reduced image data set more than other image data, which are representative of areas of the captured image outside of a target zone, to detect objects present within the target zone.
Abstract:
Disclosed herein is an apparatus and method for controlling the travel speed of a vehicle using information about a road or at least one portion thereof ahead of the vehicle. The apparatus includes a forward image sensor for photographing a forward road or portion(s) thereof, acquiring image data, and extracting information about the forward road or portion(s) from the image data using a Kalman filter. A control unit calculates a target speed required for the vehicle to travel using the forward road information. With the apparatuses and methods, vehicle safety and driving comfort can be improved.
Abstract:
A vehicle lane change aid system includes a detector that is operative to detect the presence of an other vehicle adjacent the vehicle, an indicator for providing an indication that a lane change maneuver of the vehicle may affect the other vehicle and a control receiving movement information of the vehicle. The control develops a position history of the vehicle at least as a function of the movement information. The control compares the detected presence of the other vehicle with the position history and provides an indication when a lane change maneuver may affect the other vehicle.
Abstract:
The present invention discloses a lane departure warning method, which functions to choose the data acquiring source according to brightness of the environment surrounding a vehicle and weather status so as to reduce the erroneous judgment of lane departure during image processing and analyzing. In addition, the present invention also presents a lane departure warning apparatus using the foregoing method, which comprises at least a first information acquisition unit, at least a second information acquisition and a information processing/information processing/controlling unit. The first information acquisition unit disposed on the vehicle is capable of capturing the image around the vehicle while the second information acquisition unit disposed on the bottom of the vehicle is capable of capturing image under the bottom of the vehicle. The image acquired from the first information acquisition unit and the second information acquisition unit is then sent to the processing and information processing/controlling unit for data processing. The processing and information processing/controlling unit functions to choose the first information acquisition unit or the second information acquisition unit as the data source according to brightness of the environment surrounding the vehicle so as to prevent the erroneous judgment due to the influence of surroundings and improve the accuracy of image analyzing. When the lane departure is occurred, the processing and information processing/controlling unit can operate an alarm unit to generate an alert signal to remind the driver.
Abstract:
A lane departure prevention system comprises a traveling status detecting unit for detecting current lateral displacement and current yaw angle of a vehicle relative to a lane of travel, a departure detecting unit for detecting whether the vehicle is tending to depart from the lane of travel on the basis of current lateral displacement of the vehicle relative to the lane of travel as detected by the traveling status detecting unit; and a departure avoidance control unit for controlling the vehicle to avoid lane departure when the departure detecting unit detects that the vehicle is tending to depart from the lane of travel. The departure avoidance control unit calculating the extent of control necessary to avoid lane departure on the basis of current yaw angle of the vehicle detected by the traveling status detecting unit. Provision is made for preventing lane departure on a curving as well as a straight road.
Abstract:
An imaging system for a vehicle includes an imaging sensor and a control. The imaging sensor is operable to capture an image of a scene occurring exteriorly of the vehicle. The control receives the captured image, which comprises an image data set representative of the exterior scene. The control may apply an edge detection algorithm to a reduced image data set of the image data set. The reduced image data set is representative of a target zone of the captured image. The control may be operable to process the reduced image data set more than other image data, which are representative of areas of the captured image outside of the target zone, to detect objects present within the target zone. The imaging system may be associated with a side object detection system, a lane change assist system, a lane departure warning system and/or the like.
Abstract:
A lane recognition apparatus for a vehicle is comprised of an image picking-up section which picks up a road image in front of the vehicle, a lane-marker candidate-point detecting section which detects coordinate values of a plurality of lane marker candidate points from the road image, and a road model parameter calculating section which estimates a road model parameter representative of a road shape in front of the vehicle and a vehicle state quantity of the vehicle using an extended Kalman filter, on the basis of the coordinate values of the lane marker candidate points.
Abstract:
An image processing apparatus is provided with: an image taking device (19) for taking an image in a forward direction of a movable body and outputting an image signal corresponding to the taken image; a movement vector detecting device (18, 24) for detecting a movement vector for each area of the image taken by the image taking device, on the basis of the image signal while the movable body is moving; and a distance calculating device (18, 25) for setting a standard line at a predetermined image position crossing a road edge with respect to the image taken by the image taking device, and calculating the distance to the road edge on the basis of a distribution of the movement vector on the standard line.
