    摘要： A warning system for a vehicle obtains image data by three-dimensionally recognizing a road extending ahead of the vehicle and traffic conditions, decides that driver's wakefulness is on a high level when there is any one of psychological stimuli to the driver or that driver's wakefulness is on a low level when there is not psychological stimulus to the driver, estimates the possibilities of collision and off-lane travel, and gives the driver a warning against collision or off-lane travel when there is the high possibility of collision or off-lane travel. Another warning system for a vehicle obtains image data by three-dimensionally recognizing a road extending ahead of the vehicle and traffic conditions, discriminates between automobile roads and open roads on the basis of the image data and a traveling mode in which the vehicle is traveling, determines patterns of driving operations and traveling motions in a given time at the initial stage of travel on the road when the road is identified to be an automobile road, repeats the determination of patterns at given time intervals, detects dozed driving through the comparison of a reference value and a measured value and gives the driver a warning against dozing when the driver's wakefulness declines.

    摘要： In a drive assist system of a vehicle having a function of detecting an inter-vehicle distance between vehicles and a warning is given to a driver for preventing a collision, disclosed are an apparatus for detecting a deceleration of a preceding vehicle based on a vehicle speed of the preceding vehicle, an apparatus for establishing a safe inter-vehicle distance between the vehicle and the preceding vehicle based on the deceleration of the preceding vehicle, and an apparatus for comparing the inter-vehicle distance with the safe inter-vehicle distance and for outputting a warning signal when the inter-vehicle distance is smaller than the safe inter-vehicle distance. Thus, when the deceleration of the preceding vehicle is small, the warning is not issued until the inter-vehicle distance becomes small, whereby the driver's intention can be reflected on the drive assist system.

    摘要： A warning system estimates the possibility of the off-course travel of a vehicle while traveling through a curve before the vehicle enters the curve and gives the driver a warning properly. The warning system comprises an image recognizing means for obtaining three-dimensional image data on the road extending ahead of the vehicle and the traffic environment lying ahead of the same by recognizing conditions of the road and the traffic, a curve detecting means for detecting a curve on the basis of the image data before the vehicle enters the curve, a turning speed calculating means for calculating a reference turning speed at which average drivers will drive the vehicle traveling the curve on the basis of the radius of curvature of the curve and the width of the lane represented by the image data, a relative curve sharpness detecting means for deciding whether or not the relative sharpness of the curve is critical by comparing the reference turning speed with the actual traveling speed of the vehicle, and an off-course travel estimating means for deciding, when the relative sharpness detecting means decides that the relative sharpness of the curve is critical, whether or not the driver has carried out danger avoiding operations from signals indicating decelerating operations, and, if any danger avoiding operation is not executed, deciding that off-course travel is possible and giving a warning.

    摘要： A vehicle navigation control system has primary prediction error width calculating means for calculating a primary near-distance error width between a forward extending line of the vehicle and a target path at a predetermined near-distance observing location and for calculating a primary far-distance error width between the forward extending line and the target path at a predetermined far-distance observing location. A secondary near-distance error width between a predicted path and the target path at the predetermined near-distance observing location, and a secondary far-distance error width between the predicted path and the target path at the predetermined far-distance observing location, are calculated by a secondary prediction error width calculation means. Steering angle calculating formula selecting means determines whether the target path is a straight path or a curved path with a large curvature, a constantly curved path, or other curved path in accordance with the error widths calculated by the primary and secondary prediction error width calculating means and selects an optimum formula from predetermined model formulas. Steering angle determining means substitutes the corresponding error widths into the selected model formula so as to determine a steering angle.
