CONTROL DEVICE FOR HYBRID VEHICLE

摘要

Provided is a control device that allows gear shifting to be performed efficiently and an increase in fuel consumption to be minimized in a hybrid vehicle having an electric continuously variable transmission and a step transmission. When displacement of the operating point of an engine (12) and shift control of a step transmission (20) occur at the same time, the occurrence of shift shock or the like is minimized while the energy balance is kept at the desired level because the energy balance of the entire gearshift mechanism comprising the electric continuously variable transmission (19) and the step transmission (20) is controlled by controlling the rotational change of at least one of the following: a sun gear (S0) corresponding to a "g" axis, a carrier C0 corresponding to an "e" axis, and a ring gear R0 corresponding to an "m" axis.
