The BMW active steering system utilises a double planetary gear system located at the base of the steering column to facilitate driver independent steering of the front wheels. The system is intended to offer two principal benefits; a variable steering ratio and stability enhancing corrective steering actions.

The double planetary gear system incorporates an input sun gear connected to the driver’s steering wheel, two planetary gears, an output sun gear connected to the steering pinion, and a rotating housing. If the housing is held still, the driver’s steer inputs are translated from the input sun gear, through the planetary gears (sharing a common lay shaft) to the output sun gear with a net 1:1 ratio.
