The bidirectional converter performs regenerative control to convert an inertial force of a rotor of the motor-generator to power and charge the electric power storage device when it decelerates the motor-generator from a standard revolution speed to the idle revolution speed.

In an apparatus for controlling an unmanned autonomous operating vehicle having an electric motor supplied with power from a battery for operating an operating machine, and magnetic sensors for detecting intensity of a magnetic field of an area wire and controlled to run about in an operating area defined by the area wire through wheels driven by the prime movers to perform an operation using the operating machine and to return to a charging device installed on the area wire so as to charge the battery, there is provided with a turn-back portion formed by bending the area wire at an appropriate position and again bending the area wire to return in a same direction with a predetermined space so as to divide the operating area into a plurality of parts and vehicle running is controlled to be prohibited from going across the turn-back portion.



Automatic roll-back and return-to-position for header tilt on an agricultural machine

Tue, 03 Mar 2015 08:00:00 EST

A windrower with a harvesting header with a crop cutting assembly for severing crop from the ground windrower has a header pitch sensor for measuring a fore/aft pitch angle and a hydraulic system. The hydraulic system moves the header between an operating height and a raised position, and also controls a fore/aft pitch angle. An electronics control module provides an output to activate solenoid valves in the hydraulic system to move the header between the operating height and the raised position and to select a desired pitch angle. When the header moves from the operating height to the raised position, the electronics control module operates the header hydraulic system to move the header to the zero-tilt condition, and upon lowering the header back the operating height, the electronics control module automatically returns the header to the selected pitch angle it was in at the start of the cycle.
