Abstract: A vehicle driving assist apparatus for guiding a vehicle to a target position is provided. A basic path that changes the deflection angle ? to 0 is determined, and is subjected to similarity transformation. On the basis of the similarity-transformed path, a path factoring in transition from the initial steering angle is set. Then, a correction is made such that the area in the running distance-curvature graph regarding this path becomes equal to a corresponding area regarding the basic path, thereby setting a corrected path. The corrected path is similarity-transformed, and then is re-corrected in accordance with transition from the initial steering angle. Thus, a final target path is obtained.

Abstract: A driving assist apparatus for a vehicle which calculates a path by an algorithm suitable for real-time path calculation in a vehicle-installed computing device is provided. A basic path that changes the deflection angle of the vehicle to 0 is computed from an initial vehicle position. From the basic path, a target path is computed, for example, by adding straight-line paths to the two opposite ends of the basic path. On the basis of the target path, a driving assist is performed. During the driving assist, a basic path is re-calculated. If it is determined that a similarity-enlarged path obtained through similarity enlargement of the basic path can be used to reach the target position point, a target path is re-set on the basis of the similarity-enlarged path. Then a driving assist is performed on the basis of the re-set target path.

Abstract: A driving assist apparatus and method for a vehicle capable of guiding the vehicle at appropriate vehicle speed in accordance with the path is provided. The alarm vehicle speed for informing a driver of overspeed during driving assist is set lower for a changing steer region than for a fixed steer region. The lower alarm vehicle speed is set before the changing steer region is entered. Therefore, in the changing steer region, the vehicle speed can be sufficiently reduced, so that a set amount of steering can be accomplished. In the fixed steer region, the vehicle speed can be increased so as to reduce the time of travel.
