Abstract:
A hydrostatic transmission with which a braking operation is realized in which at least one traction motor which acts as a pump is supported via a closed circuit on an adjustable axial piston pump which acts as a motor, and which in turn is supported on an internal combustion engine. Since overspeeding of the latter should be avoided, pilot control is performed with a rotational speed that is subcritical for the internal combustion engine, and thereafter closed-loop control is performed with a closed-loop controller which outputs a corrective value in a manner dependent on the rotational speed deviation between the present rotational speed and the maximum and thus ideal rotational speed of the internal combustion engine.

Claim (Index 12):
A method for the closed-loop control of a braking operation with a hydrostatic transmission for a traction drive of a mobile working machine, comprising:\n pivoting a primary unit back; performing pilot control of the pivot angle or of the swept volume; and performing closed-loop control of the pivot angle or of the swept volume by adding a corrective value to a pilot-controlled pivot angle or to a pilot-controlled swept volume, wherein the hydrostatic transmission includes\n the primary unit including a driveshaft coupled to an internal combustion engine of the traction drive, \n a secondary unit coupled to an output of the traction drive, \n two working lines of a closed circuit each configured to fluidically connect the primary unit and the secondary unit, \n an electrical control unit configured to control the pivot angle and the swept volume of the primary unit during the braking operation of the hydrostatic transmission, and \n a closed-loop controller configured to output the corrective value.
