Steering control system for moving vehicle

摘要

A steering control system for a moving vehicle causes the vehicle to travel along a predetermined traveling course in a region in which a predetermined working operation, such as grass cutting or the like, is to be performed by the vehicle as it moves along the traveling course. An obstacle sensor is mounted on the vehicle, and when the sensor detects presence of an obstacle on the predetermined traveling course, the steering control system operates to cause the vehicle to leave the predetermined traveling course and to detour around the obstacle while maintaining a substantially constant distance between the obstacle and the moving vehicle. The control system is also operative to determine whether the obstacle is stationary or movable and, upon completion of the vehicle travel along the predetermined course, is operative to determine whether a movable obstacle has been removed from the predetermined course and, if so, causes the vehicle to perform its working operation in that portion of the region in which the working operation was not previously performed due to its detour around the obstacle.
