HYBRID DRIVE AND METHOD OF ITS CONTROL Russian patent published in 2011 - IPC B60L11/14 B60W20/00 

FIELD: transport.

SUBSTANCE: invention relates to hybrid drives. In compliance with first, second and third versions, hybrid drive comprises internal combustion engine, electric machine assembly, transmission, and control unit. Transport facility comprises one of proposed versions of hybrid drive. In compliance with first, second and third versions, method of control comprises adjusting said drive to allow ICE to select between idle and operating conditions. In compliance with first version, method comprises steps whereat feedback signals and control signals are received to generate output signals. In compliance with second version, it comprises steps whereat gearbox is engaged to transmit torque to engine, and engine starting torque is defined to compensate for sharp variations of torque. In compliance with third version, it comprises steps whereat torque at electric machine output is reduced to change the gears and start ICE by electric machine and to transmit additional torque to electric machine. Proposed control units effects control in compliance with one of above described versions.

EFFECT: better equalising of abrupt torque variations.
