Filed: 2001-12-28
Abstract: PROBLEM TO BE SOLVED: To provide a control method for preventing an automobile from deviating from a lane, by which an unmanned traveling vehicle does not erroneously issue alarm even in a safe traveling state on a curved road. SOLUTION: By the control method of the present invention, curvature information of a forward curved road and information concerning the width of the lane are transmitted before the vehicle enters the curved road through the use of a DSRC which is a communication system between the vehicle and road side equipment, a lane deviation determination standard angle to be applied in curved sections is set by using transmitted road information and information from a camera which is arranged in the vehicle and, then, a difference between the standard angle and a center value of left and right lane marker angles is compared with a critical value to determine whether the vehicle is deviating from the lane or not. Thus, deviation from the lane in the curved section of the road is correctly alarmed and, then, safety is secured in traveling by correct information.

Abstract: An overrunning coupling assembly includes a notch plate and an annular coupling pocket plate positioned in face-to-face relationship with respect to each other along a common axis. The pocket plate includes strut pockets disposed at angularly spaced positions about the axis. The notch plate includes notch recesses at angularly spaced positions about the common axis and positioned in juxtaposed relationship with respect to the strut pockets. The notch plate includes an inner circumferential rail at a radially inward side of the notch recesses and an outer circumferential rail at a radially outward side of the notch recesses. Torque-transmitting struts are positioned in the strut pockets. Each strut has first and second ears at one edge thereof for enabling pivotal motion of the struts about an ear axis intersecting the ears. The opposite edge of each strut is engageable with one of the notch recesses whereby one-way torque transfer may occur between the plates. Each opposite edge has first and second corners. Each strut pocket is sufficiently enlarged to allow pivotal movement of each strut about a strut axis which is parallel with the common axis, thereby enabling one of the first and second corners to be selectively supported by one of the inner and outer circumferential rails to prevent the struts from slapping against the notch recesses as the notch plate and pocket plate are respectively counterrotated.
