Technology for monitoring a charging current line of a drive train connected to a power generator

摘要

A technique for monitoring a charging current line (208) of a drive train of a motor vehicle that is electrically connected on the output side to at least one current generator (202) is described. A device aspect of the technology comprises an engine controller (102) which sends a specification of at least one output variable of the at least one power generator (202) of the motor vehicle via a data bus (204) to a controller (206) of the at least one power generator (202) and a feedback from the controller (206) of the at least one power generator (202) via the data bus (204). A determination unit (102; 206) of the device is designed to determine a short circuit (302) in the charging current line (208) as a function of the specification, a measured value of the at least one output variable and / or the feedback.
