ABSTRACT:
A system for automatically guiding a vehicle provided with pneumatically tired wheels comprises first and second rollers 7, 7' which follow a rail 8 extending in the path of movement of the vehicle. The first roller is supported by a fork-shaft 9, 10 extending in the direction of movement of the vehicle and capable of oscillating vertically about a horizontal axis 11. It is fastened to a turret 12 connected to at least one coupling bar 17 hinged to a steering lever 6. The second roller is supported by a second support arm extending in the opposite direction, which may also oscillate vertically about a horizontal axis and pivot horizontally independently of the turret, to a limited extent. The vehicle can be guided alternately either by a mechanical type of automatic system, used when the vehicle moves on an appropriate infrastructure, or manually by the driver, when the vehicle moves autonomously.
