Abstract
A diagnosis management system for a hydrostatic displacement unit, including a control unit for controlling a drive motor, a hybrid control unit for controlling the motor control unit on the basis of at least one desired acceleration signal and one desired deceleration signal for the drive motor, a gear control unit for controlling the motor control unit on the basis of at least signals derived from a continuously variable gear, and a control unit for a digital displacement unit, for controlling at least one pump motor as the digital displacement unit is disclosed. The control unit for a digital displacement unit has at least one diagnostic interface, which detects operating values and/or operating states in order to detect system errors in the pump motor, a sensor unit portion associated with the pump motor, and/or a power electronics portion associated with the pump motor; and at least one calculation portion, which preprocesses the operating values and/or operating states detected by the diagnostic interface. The at least one diagnostic interface and the at least one calculation portion are disposed for operating in a first system direction for diagnosis and for determining a correction of incident system errors, and in a second system direction for diagnosis and/or for performing the correction of incident system errors. A diagnosis management method can be performed by the diagnosis management system.
