Abstract
A motor speed control method and system for improving the performance of a running resistance evaluation of a hybrid electric vehicle are provided. The method includes determining whether a vehicle satisfies a running resistance evaluation start condition. When the vehicle satisfies the running resistance evaluation start condition, the speed of a motor is adjusted, which adjusts an input speed of a transmission to be equal to an output speed of the transmission. A speed adjustment of the motor is then completed using the speed of the motor and the output speed of the transmission.
