  • Patent number: 7100721
    Abstract: A hybrid vehicle drive control apparatus including 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.
    Type: Grant
    Filed: August 5, 2003
    Date of Patent: September 5, 2006

  • Patent number: 6994652
    Abstract: A hybrid type vehicle drive control device for preventing an engine from being stalled as a generator fixing mechanism is released. The hybrid type vehicle drive control device includes a generator connected differentially rotatably and mechanically to the engine, a generator fixing mechanism for mechanically stopping the rotation of the generator, a braking state decision device for deciding a braking state by a braking brake and a release control device for releasing the generator fixing mechanism when it is decided that an abrupt braking has been performed. When the abrupt braking is performed, the generator fixing mechanism can be released to prevent the engine speed from lowering and the engine from being stalled.
