Vehicle hybrid drive system has intermediate DC voltage circuit between electrical generator and electrical drive divided into 2 partial circuits each coupled to respective drive motor

摘要

The hybrid drive system has an electrical generator (2) coupled to an IC engine (1) and connected via a rectifier, an intermediate DC voltage circuit coupled to an electrical energy store (7) and a DC/AC converter to an electric drive motor (5,6). The intermediate DC voltage circuit is divided by a switch (8) into 2 partial circuits (3,4), each connected to at least one drive motor via a respective DC/AC converter. An independent claim for a regulation method for a vehicle hybrid drive system is also included.
