Publication number: 20160288781Abstract: 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.Type: ApplicationFiled: November 4, 2015Publication date: October 6, 2016Inventors: Jae-Yun Shim, Tae-Young Chung, Chun-Hyuk Lee, Yong-Hoon Lee, Kyung-Taek Lee, Jang-Hyo Lee, Dong-Su Ha, Young-Kwan Ko, Keum-Jin Park, Byung-Hoon Yang
