Vehicle steering control system

摘要

A steering probe for controlling the steering of an agricultural vehicle along a path corresponding to a crop row includes a yoke pivotally mounted to the vehicle and having arms extending downwardly on opposite sides of the crop row. The yoke is pivotally mounted adjacent its upper end for pivotal movement about a horizontal axis. A sensor is connected to the probe adjacent its pivotal mounting to the vehicle, and senses the rotational position of the yoke. The lower ends of the yoke engage the opposite sides of the crop row, and the yoke pivots from its neutral position about the pivotal axis whenever the vehicle becomes misaligned with the crop row. The sensor senses the rotation of the yoke and causes the vehicle to be steered to compensate for the misalignment with the crop row.
