Claims18
A hybrid vehicle drive control apparatus, comprising:
- an electric generator mechanically connected to an engine so as to have a differential rotation with respect to the engine;
- a generator brake for mechanically stopping a rotation of the generator;
- and
- a controller that gradually decreases a generator torque while engaging the generator brake.
A method of operating a hybrid vehicle, comprising:
- engaging a generator brake;
- mechanically stopping rotation of a generator that is mechanically connected to an engine so as to have a differential rotation with respect to the engine, via the generator brake;
- and
- gradually decreasing a generator torque concurrently with the mechanically stopping.
