VEHICULAR CONTROL DEVICE AND METHOD OF CONTROLLING A VEHICLE
First Claim
1. A vehicular control device for a vehicle with an internal combustion engine and a rotating electric machine serving as driving sources, said vehicle including a first rotating electric machine coupled with an output shaft of said internal combustion engine and generating electric power based on motive power of said internal combustion engine, and a power split device transmitting the motive power of said internal combustion engine to a wheel shaft of said vehicle, said power split device splitting the motive power received from said internal combustion engine into one of driving force for said wheel shaft and motive power for said first rotating electric machine, between said power split device and said wheel shaft a second rotating electric machine being provided to provide said wheel shaft with driving force, the vehicular control device comprising:
- a detection unit detecting a state of an operation member operated to select a shift position of a plurality of shift positions corresponding to a plurality of stages, respectively, each with a lower limit value for a rotation speed of said internal combustion engine; and
an operation unit connected to said detection unit, said operation unit;
determining from said state as detected whether said shift position has been changed;
setting a rate of change applied to the rotation speed of said internal combustion engine in accordance with an elapsed period of time elapsing after said shift position was previously changed before said shift position is currently changed; and
controlling said first rotating electric machine in accordance with said rate of change, as set, to allow said internal combustion engine to have the rotation speed set at least said lower limit value corresponding to said shift position.

Abstract
An ECU executes a program including the steps of: calculating a period of time elapsing after a stage was immediately previously shifted before the stage is currently shifted; if the elapsed period of time is at most a predetermined period of time, performing a process to advance an elevation rate applied to the rotation speed of an engine; determining an elevation rate applied to the rotation speed of the engine; and performing a process to control elevating the rotation speed of the engine.
