    • In a particular species of the preferred embodiment, the invention contemplates a land traveller such as a farm tractor pulling a passive load such as a plough, disc or the like. A control device for directing or controlling the path of travel of the vehicle over a field, and also regulating or controlling the depth of penetration of the plough or disc into the surface of the ground according to a predetermined depth irrespective of the terrain profile. The path control system consists of locating in a predetermined way, a track whose position is sensed by an electromagnet, and the relative position of the magnet is sensed by appropriate devices such as resistence measuring devices (strain gauges or variable resistors or reostats), photoelectric devices whose values are decoded through a microprocessor whereby steering of the prime mover along the predetermined path is maintained.
    • 在优选实施例的特定种类中,本发明设想了一个陆上旅行者,例如拉动诸如犁,盘等的被动负载的农用拖拉机。 用于引导或控制车辆在场上的行进路径的控制装置,并且还根据预定的深度调节或控制犁或盘进入地面的深度,而与地形轮廓无关。 路径控制系统包括以预定的方式定位其位置由电磁体感测的轨道,并且磁体的相对位置由诸如电阻测量装置(应变仪或可变电阻器或再稳定器)之类的适当装置感测,光电 其装置的值通过微处理器解码,从而维持原动机沿预定路径的转向。
