摘　　要：当前航路段是船舶计划航线自动监控的关键参数,是计算偏航距、到下一转向点的方位和距离等计划航线监控参数的基础。论文针对基于电子海图的数字化航海作业过程,在构建一定的航路段解算规则基础上,提出一种船舶计划航线航路段自动解算算法,实现了复杂计划航线航路段的自动解算。The current route leg is a key parameter during the ship automatic monitoring, and which is the basic feature for calculating cross track distance, the distance and bearing to the next waypoint. This paper presents a current route leg computing algorithm based on the method using perpendicular lines to waypoints （including route terminal）. It is an effective and efficient solution to calculate route monitoring parameters in anfractuous routes by constructing computational rules.
