摘要： A gear shifting control method for an electric vehicle includes an operation range determination step of determining, by a controller, whether a current revolutions per minute (RPM) of a motor falls within a constant torque range or a constant power range when gear shifting is initiated between a first shift gear and a second shift gear. A variable control step controls an operating power of a cone clutch by adjusting an operating tilt if it is determined that the RPM of the motor falls within the constant torque range in the operation range determination step. A constant control step controls the operating power of the cone clutch to be constant if it is determined that the RPM of the motor falls within the constant power range in the operation range determination step.

摘要： A neutral controlling method of a synchronizer includes: a primary moving step of moving a sleeve in one direction by a shift mechanism until the sleeve contacts a first stopper of a first clutch gear; a secondary moving step of moving the sleeve in the other direction by the shift mechanism until the sleeve contacts a second stopper of a second clutch gear; and a neutral position moving step of moving the sleeve to a neutral position between the two clutch gears. In particular, in the neutral position moving step, the sleeve moves in one direction as much as a half of a stroke and the stroke of the sleeve is a summed value of a straight distance between the first stopper and the second stopper with an invalid stroke formed due to a clearance between parts of the shift mechanism and the synchronizer.
