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.

Braking and auxiliary driving means for an internal combustion engine

This invention relates to an electric braking and auxiliary engine mechanism for a motor vehicle including a rotary machine coupled with the crank shaft of the internal combustion engine which drives the axle of the vehicle. This mechanism is characterized in that squirrel-cage polyphase induction machine is used as the rotary machine which is fixedly connected to the crank shaft, and the squirrel-cage polyphase induction mechanism is fed with a revolving magnetic field which is variable either positive or negative direction by an invertor, so that the squirrel-cage polyphase induction machine may be utilized either as a power generator or a motor.
