Abstract:
A method of controlling a vehicle including a driving force source for generating the driving force, a cogwheel type transmission provided with a plurality of cogwheel rows, and a plurality of torque transfer means provided between an input shaft and an output shaft of said transmission, at least one above torque transfer means being a friction transfer means, comprising the Steps of controlling said friction transfer means when shifting from one cogwheel row to the other cogwheel row, setting a target synchronous rotation speed based on an output rotation speed of said transmission and at least one of parameters indicative of the state of said driving force source or said transmission, and setting an command value to said friction transfer means so that an input rotation speed of said transmission may be synchronized with said target synchronous rotation speed, further comprising the Steps of:setting a target required shift time based on at least one of parameters indicative of the state of said driving force source or said transmission, and correcting the command value to said friction transfer means so that a required shift time from a shifting start to a shifting end may approach at said target required shift time.
