Patent number: 10927515Abstract: A self-propelled milling machine includes a controller which continuously locates an alterable position of a loading surface and of a slewable transport conveyor relative to a machine frame, or the position of the loading surface relative to the transport conveyor, and automatically controls one or more of the slewing angle, the elevation angle and the conveying speed of the transport conveyor, wherein discharged milling material impinges on pre-calculated points of impingement within the loading surface. The controller determines correction factors for the control parameter(s) as a function of a transverse inclination about the longitudinal central axis of the loading surface, a position angle between the longitudinal central axis of the loading surface and the longitudinal central axis of the transport conveyor or that of the machine frame, and/or the position of the pre-calculated point of impingement relative to an end of the loading surface lying on the longitudinal central axis.Type: GrantFiled: November 15, 2018Date of Patent: February 23, 2021Inventors: Cyrus Barimani, Christian Berning, Tobias Krista, Bernd Walterscheid
