    Abstract: Apparatus provides a signal to an operator of a following vehicle when it is necessary to take appropriate action to avoid coming within a predetermined distance of a lead vehicle proceeding in the same direction. From initial predicted forward velocities and distances of the lead and following vehicles, the signal apparatus (1) derives subsequent predicted velocities and positions of the lead and following vehicles and a subsequent predicted distance D(t) between the lead vehicle and the following vehicle after a projected short time interval while assuming a predetermined braking action of the following vehicle (2), derives and compares the subsequent predicted distance D(t) between the lead vehicle and the following vehicle with a least distance D.sub.LEAST, and (3) sets the least distance D.sub.LEAST equal to the subsequent predicted distance D(t) between the lead vehicle and the following vehicle if the latter is smaller. The signal apparatus iteratively applies the calculating means, beginning with forward velocities and positions derived from sensor signals as the initial predicted forward velocities and distances in the first iteration and generates a signal if and when the least distance becomes smaller than a minimum allowable distance D.sub.MIN.

    Abstract translation: 当需要采取适当的动作以避免进入在相同方向前进的牵引车辆的预定距离内时，装置向后续车辆的操作者提供信号。 信号装置（1）从初始预测的前进速度和前进车辆的行驶距离和后续车辆的距离得出后续车辆和后续车辆的预测速度和位置以及随后的前车辆与后续车辆之间的预测距离D（t） 在假设后续车辆（2）的预定制动动作的情况下的预定的短时间间隔，以最小距离DLEAST导出并比较引导车辆与后续车辆之间的后续预测距离D（t），以及（3） 最小距离DLEAST等于引导车辆和后续车辆之间的后续预测距离D（t），如果后者较小。 信号装置迭代地应用计算装置，从前向速度和从传感器信号导出的位置开始，作为初始预测的前进速度和第一次迭代中的距离，并且如果和当最小距离变得小于最小允许距离DMIN时产生信号。
