Patent ID: 8210985

Claim:
A vehicular power transmission control apparatus applied to a vehicle comprising an internal combustion engine and an electric motor as power sources, comprising: a transmission including an input shaft to provide a power transmission path between said input shaft of said transmission and an output shaft of said internal combustion engine, and an output shaft to provide a power transmission path between said output shaft of said transmission and drive wheels of said vehicle, wherein said transmission is capable of adjusting a transmission reduction ratio which is a ratio of a rotational speed of said input shaft of said transmission to a rotational speed of said output shaft of said transmission; a changeover mechanism which is capable of changing a connection state of an output shaft of said electric motor to any one from two or more states comprising, an input-side-connection state in which a power transmission path is provided between said output shaft of said electric motor and said input shaft of the transmission, an output-side-connection state in which a power transmission path is provided between said output shaft of said electric motor and said output shaft of said transmission without involving said transmission, and a non-connection state in which neither a power transmission path between said output shaft of said electric motor and said input shaft of said transmission, nor a power transmission path between said output shaft of said electric motor and said output shaft of said transmission is provided; and control means for selecting one of said connection states based on a parameter correlating with a vehicle speed and a parameter correlating with a required driving torque obtained based on an operation applied to an acceleration operating member by a driver of said vehicle, and for controlling said changeover mechanism in such a manner that an actual connection state of said output shaft of said electric motor coincides with said selected connection state.
