Patent ID: 8352139

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 providing a power transmission path between an 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 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 of an input-side-connection state, an output-side-connection state, and a non-connection state as an essential state, said input-side-connection state being a state in which a power transmission path is provided between said output shaft of said electric motor and said input shaft of said transmission, said output-side-connection state being a 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 said non-connection state being a 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; means for determining whether or not a kick-down-condition is satisfied based on an increase in an operation amount of an acceleration operating member operated by a driver of said vehicle, said kick-down-condition being a condition for increasing said transmission reduction ratio; and means for controlling, when and after said kick-down-condition is satisfied, firstly said changeover mechanism so as to perform a changeover operation for changing said connection state of said output shaft of said electric motor, and secondly said transmission so as to perform a gear position shifting operation for increasing said transmission reduction ratio after said changeover operation is completed.
