Abstract
Methods and systems are provided for a starter/generator in a vehicle drivetrain. In one example, a system may include an integrated starter/generator (ISG) rotationally coupled to an engine crankshaft via a belt drive system, the belt drive system including a first decoupler configured to engage a shaft of the ISG in a first torque transfer direction only and a second decoupler configured to engage the shaft of the ISG in a second torque transfer direction only, the second torque transfer direction opposite the first torque transfer direction. In this way, hubloads that occur while transitioning the ISG between driving the belt drive system and being driven by the belt drive system may be reduced while a response time of the transitioning may also be reduced.
