Itinerary following device for a vehicle
First Claim
1. An itinerary following device for a vehicle with a driving station and having wheels for contacting the ground, and in particular an automotive vehicle such as an agricultural machine, adapted to permit the vehicle to follow with fidelity in the course of a passage of the vehicle over a given surface, a previously recorded path, said device comprising:
- recording means for recording the path to be followed and means for comparing the position of the vehicle in the course of its passage with the recorded path for the purpose of actuating steering means for steering the vehicle, and causing the vehicle to be made to travel in the opposite direction relative to the direction of the recorded path, and indicating means for indicating successive directions taken by said vehicle, including a graduated magnetic element, the magnetic element being mounted on the vehicle by a support made from a non-magnetic material and located at a sufficient distance from the metallic mass of the vehicle to ensure that the magnetic influence of the metallic mass is negligible, said indicating means further comprising a viewing means for viewing from said driving station, including a magnifying optical system disposed in front of the graduated magnetic element and at least one viewing element disposed at the driving station.

Abstract
The invention concerns a device for recording and reading the itinerary travelled through by a vehicle and in particular an automobile vehicle such as an agricultural machine. The device is adapted to reproduce on an indicator band a trace of the path followed by the vehicle over a given surface so as to enable the operator to follow, with fidelity, in the course of a second passage of the vehicle, the trace of the preceding passage which permits, for example in the case of spraying, a rational treatment of the surface to be treated in strictly parallel strips with no omission or overlapping of zones. The device comprises a programmer constituted by the indicator band which travels at a speed which is proportional to the speed of the vehicle in front of a movable recording element which is controlled by the steering of the vehicle and reacts in accordance with the variations in the steering. The device further comprises a device for reading the recorded program and a device for indicating and displaying the successive directions assumed by the vehicle.
