In order to enhance the operational reliability of an electric drive unit of a vehicle comprising a generator (G), which is operated by an internal combustion engine (V), and drive motors (M1, M2), which are connected to said generator via a d.c. link, the generator and drive motors are subdivided into partial units (TG1, TG2; TM11-TM22), and power electronics units (TGLE1, TGLE2; TM1LE1, TM1LE2...) are assigned to these partial units. The partial units, which correspond to one another and which consist of the generator, motors and of power electronics units, each form a separate drive circuit (AK1, AK2) whose components are supplied with control signals by a specifically assigned system control unit (1, 2). The system control units (1, 2) that are interconnected via an information exchange channel (IAK) can undertake compensation measures in their drive circuit or in the other drive circuits in the event of a complete or partial failure of a drive circuit (AK1, AK2). Alternatively to the assignment of one system control unit (1, 2) at a time to a drive circuit, several system control units can also be connected to the individual drive circuits via bus connections or via multiple single channels. |
