Abstract

A method of controlling a secondary drivetrain of an electrically powered vehicle includes receiving a connect request for a disconnect mechanism, which includes a first and second clutch member. The second clutch member is biased to a disconnected state from the first clutch member and axially moveable into a connected state to transfer torque from an electric motor to the wheels. An initial current is applied to an actuator of the second clutch member, but the initial current does not overcome the bias on the second clutch member. The electric motor rotates the first clutch member such that a speed difference relative to the second clutch member is reduced below a threshold level. The method applies an additional current to the actuator, which overcomes the bias and connects the clutch members to transfer torque. The time to connect the clutch members is reduced because the initial current was already applied.
