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: An automotive lane deviation prevention (LDP) apparatus includes a control unit connected to a yawing-motion control actuator for LDP control purposes. The control unit determines, based on information regarding a lane marking line detected based on a picture image in front of a host vehicle, whether the host vehicle is in a state FLDnull0 where there is an increased tendency for the host vehicle to deviate from the driving lane. The control unit executes, based on a state Fdwnull0 where the host vehicle is traveling on predetermined irregularities formed on or close to the lane marking line and the information regarding the lane marking line, vehicle yawing motion control by which the host vehicle returns to a central position of the driving lane, in a lane-marking non-detecting state Fcamreadynull0 where the lane marking line is out of an image pick-up enabling area.

Abstract: A method for detecting the position of a vehicle in a predetermined area includes: detecting the magnitude and the angle of incremental motion vectors relating to the movement of the vehicle by means of a first sensor device; automatically fixing the vehicle at predetermined points within the predetermined area whenever the vehicle passes a corresponding point; and detecting the current position of the vehicle in the predetermined area by vectorial summation of the detected incremental motion vectors with respect to the position vector to the current reference position. The automatic fixing of a respective reference position of the vehicle at predetermined points is carried out by means of a second sensor device, which interacts in a non-contacting manner with a respective reference marking at the corresponding point within the predetermined area. The respective reference marking has reflective and non-reflective areas which the second sensor device simultaneously scans by means of at least two signals, with the coordinates of the reference position of the vehicle relative to a reference position of the reference marking and, optionally, the through-movement angle being determined by evaluating the time profile of the reflected intensity of the signals.

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: An image pick-up means mounted in the motor vehicle picks up a side direction of a driver's own vehicle. An approaching object detecting means detects an approaching degree of an approaching object which approaches his own vehicle from a side direction road crossing his own vehicle on the basis of two images picked up at two timings apart by a prescribed interval by the image pick-up means. A danger decision means decides a danger on the basis of the approaching degree. In such a configuration, a side-monitoring apparatus for a motor vehicle can accurately know the danger of collision with the object approaching from the side direction road.

Abstract: A camera unit 10 is mounted on a vehicle 3. When an attempt is made to park the vehicle 3 in a parking lot, a predicted path 5a and guidelines 5b are displayed on an information display 4 together with an image. Data to be used for displaying the predicted path 5a and the guidelines 5b are stored beforehand in internal memory of an image processing circuit 19 provided in a parking assist ECU 6 so that the data can be selected in accordance with specifications, such as the type of the vehicle 3. The predicted path 5a is computed on the basis of a steering angle detected by a steering angle sensor provided in an exposed portion of the steering shaft 11. The length or color of the predicted path 5a is changed in accordance with the speed of the vehicle 3. Further, a vehicle driving support system is provided with a back sonar 17, and hence the length or color of the predicted path 5a is also changed in accordance with the result of detection of an obstacle.

Abstract: In an environment monitoring system for a vehicle, when a detecting means decides that an approaching vehicle cannot be detected by an image processing means, a waning means gives warning of this fact. Thus, the environment monitoring system permits one's own vehicle to run with safety even when the approaching vehicle cannot be detected.
