Patent number: 11485216Abstract: A transmission system includes an input shaft, a transmission housing, and a planetary gear system rotatably coupled to the input shaft. The planetary gear system has a first and second gear ratio. The transmission system additionally includes an output shaft, a first electric machine, a second electric machine, and a shifting assembly. The shifting assembly includes a first stationary clutch element and a second stationary clutch element. The first electric machine is configured to apply rotational torque to the planetary gear system to synchronize rotational speed of the planetary gear system when moving between the first and second gear ratios, and the second electric machine is configured to provide rotational torque to the output shaft when the first electric machine applies rotational torque to the planetary gear system to synchronize rotational speed of the planetary gear system when moving between the first and second gear ratio.Type: GrantFiled: June 24, 2021Date of Patent: November 1, 2022Assignee: BorgWarner Inc.Inventors: Keith Van Maanen, Joel Maguire
