Braking and auxiliary driving means for an internal combustion engine
First Claim
1. A braking and auxiliary driving mechanism for an internal combustion engine in a motor vehicle, comprising:
- a squirrel-cage polyphase induction machine coupled to a rotary shaft of the internal combustion engine, said squirrel-cage polyphase induction machine including a polyphase AC circuit;
an electrostatic capacitive circuit serving as an electricity storage means, said electrostatic capacitive circuit including a DC circuit comprised of a plurality lines connected between common terminals, wherein each line includes a plurality of capacitors connected in series, said plurality of capacitors being distributed in disbursed fashion around said motor vehicle, and wherein each line in said electrostatic capacitive circuit comprises a plurality of resistors connected in series and a node point between each of said plurality of capacitors being connected to an associated node point between each of said plurality of resistors, each of said plurality of resistors having substantially a same resistance value;
an inverter circuit which couples said polyphase AC circuit of said squirrel-cage polyphase induction machine and said DC circuit of said electrostatic capacitive circuit and provides electrical energy between said polyphase AC circuit and said DC circuit; and
a control circuit which controls said inverter circuit.

Abstract
A braking and auxiliary driving unit for an internal combustion engine which produces braking and auxiliary motive power by converting electrical energy in both directions between a polyphase AC circuit of a squirrel-cage polyphase induction machine linked to the rotary shaft of the internal combustion engine and the DC circuit of an electricity storage means, the electricity storage means comprises an electrostatic capacitive circuit. A low-voltage storage battery is provided in addition to this electrostatic capacitive circuit, and this can be coupled to the electrostatic capacitive circuit by a bidirectional DC-to-DC converter.
