Abstract: A method and apparatus (10) for providing navigation guidance via a land vehicle by providing a navigation route planner (24) having a road network database (12) for planning a navigation route along the road network, determining a current estimated position of the land vehicle, communicating maneuver instructions to a driver of the land vehicle at a predetermined maneuver distance base value before the land vehicle reaches a required maneuver along the planned navigation route, and detecting and quantifying current environmental travel conditions for assisting a navigation device in guiding the land vehicle along the planned navigation route.

Abstract: An improved land vehicle navigation apparatus (10) and method for automatically planning a recovery route upon detection of a route departure. The land vehicle navigation apparatus (10) comprises a route planner (22) for planning an original route (88) for a land vehicle (2), via fixed road paths, wherein the original route includes multiple route segments, a start location, and at least one destination, including an original destination, and a position determiner (14) for determining an estimated current position of the land vehicle (2) and route storage for storing the original route segments into memory (24). The improvement comprises an automatic recovery route planner (56) for automatically planning a recovery route to the original route (88) upon detecting a route departure using recovery route planning criteria including designating at least some of the stored original route segments as a destination thereby eliminating the need for planning a completely new route and reducing recovery route planning time.

Abstract translation: 一种改进的陆上车辆导航装置（10）以及在检测到路线离开时自动规划恢复路线的方法。 地面车辆导航装置（10）包括路径规划器（22），用于通过固定道路规划陆地车辆（2）的原始路线（88），其中原始路线包括多个路线段，起始位置和 至少一个目的地，包括原始目的地，以及用于确定陆上车辆（2）的估计当前位置的位置确定器（14）和用于将原始路线段存储到存储器（24）中的路线存储器。 该改进包括自动恢复路由规划器（56），用于在使用恢复路由规划标准检测到路由离开时自动规划到原始路由（88）的恢复路由，包括将至少一些所存储的原始路由段指定为目的地，从而消除 需要规划一条全新的路线，减少路线规划时间。
