HYBRID VEHICLE CONTROL DEVICE

摘要

A hybrid vehicle (10) comprises: an engine (12); an electric motor (MG) functioning as a driving source; and a multistage automatic transmission (18) for selectively establishing a plurality of gear stages from predetermined speed change lines on the basis of vehicle traveling states. In a control device for the hybrid vehicle (10), at least part of a switching line and at least part of the speed change lines are shared with each other, the switching line being used for determining the switching between an EHV travel mode in which both the engine (12) and the electric motor (MG) are used as driving sources and an EV travel mode in which the electric motor (MG) is exclusively used as a driving source. The stop control and speed change control of the engine (12) are thereby synchronously executed, so that the occurrence of shock can be suppressed and the controls can be preferably prevented from becoming complicated.
