Abstract

1364479 Automatic vehicle control ROBERT BOSCH GmbH 6 Oct 1971 [7 Oct 1970] 46375/71 Addition to 1342633 Heading B7H [Also in Division G3] The automatically controlled vehicle of the parent Specification 1,342,633 includes a monitoring device for continuously monitoring the position of the vehicle relative to a boundary of the surface to be travelled by the vehicle, the monitoring device including at least one trans-- mitter for emitting signals and at least one receiver for receiving signals reflected from the boundary, the monitoring device being adapted to exert an influence upon the steering device for the vehicle so as to maintain the vehicle on a desired path of travel. As described the vehicle 1 has a transmitter 4 which emits electromagnetic or mechanical oscillations towards a boundary 3 which is parallel to the desired path of travel. The reflected signal is detected by one or more receivers 5, 6, 7, 8, 9 and the signals from the receivers 5 to 9 are passed to a digitalanalogue converter 10. The output from the converter 10 is passed, via a variable resistance 11, to an amplifier 12, the output of which controls a steering motor 14 to maintain the vehicle on the desired path of travel. The movable tap of the variable resistance 11 is mechanically connected to a servomotor 13 which moves the tap in accordance with the distance of the vehicle from the boundary 3, the result being that the total amplification of the control circuit remains constant. In a modification the signals from the transmitter may be directed towards an end wall of the room, as opposed to a side wall, and the monitoring device may be rotated through 180 degrees. Alternatively two monitoring devices may be provided.
