Abstract:
1. 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, 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.
