Abstract
A shift control method of a hybrid electric vehicle includes: determining a speed control torque based on a result of comparing a speed of an input end of a transmission with a target speed of the input end of the transmission according to a shift signal; distributing the speed control torque to a second motor connected directly to the input end of the transmission; and distributing a residual speed control torque to a first motor connected selectively to the second motor through an engine clutch based on whether the engine clutch is locked up when the speed control torque is greater than a charging limit torque of the second motor.
