摘要： A method of controlling a continuously variable electric drivetrain (CVED) including a high ratio traction drive transmission and at least one of a first motor-generator and a second motor-generator is disclosed. The method includes the steps of receiving a an output speed, determining a kinematic output speed, and determining a slip state of the high ratio traction drive transmission based on a comparison of the output speed to the kinematic output speed.

摘要： An electric drive axle of a vehicle includes an electric motor having an output shaft. An idler assembly is drivingly coupled to the electric motor and a differential. The idler assembly includes a first gear-clutch assembly to facilitate a first gear ratio and a second gear-clutch assembly to facilitate a second gear ratio.
