2011 BMW X3 Denver- Active Steering & Active Roll Stabilization

BMW has pioneered many safety features over the years and Gebhardt BMW would like to explain how they work.  The 2011 BMW X3 Denver is equipped with Active Steering. It works to provide you stability as you travel and actively engages when a change in terrain occurs to attempt to keep your vehicle from oversteering or from rolling.  Let’s begin by watching a Youtube video explaining Active Steering by dubrananc.

Active Steering

2011 BMW X3 Denver Active Steering

BMW introduced Active Steering to the market in 2003 and in addition to impressing BMW drivers everywhere; it was awarded the Innovation Award of Germany. Active Steering in the 2011 BMW X3 Denver combines conventional rack and pinion gear with a planetary gear and an electric motor. It can modify the driver steering input though there is still a mechanical link between the steering wheel and front axle. In case of a steering failure the electric motor in the 2011 BMW X3 Denver will immediately be locked which keeps the link between steering wheel and front axle fully operational.

Part of the Active Steering system is a conventional hydraulic power steering system that limits the steering wheel torque to a reasonable value. The continuously variable servotronic power steering system can adjust the actual steering support to virtually every driving situation.  Additionally there is a separate ECU and transducers measuring the 2011 BMW X3 Denver yaw rate and lateral acceleration.  Active Steering intensely communicates with other in car systems particularly with the DSC controller unit.  The most important part of Active Steering in the 2011 BMW X3 Denver is the variable steering ratio. The technology allows for a variable steering ratio based on your speed. At low speeds, steering in the 2011 BMW X3 Denver is nimble (10:1) for easy navigation in tight spaces. At high speeds, greater movement of the steering wheel is required to turn the front wheels the same amount (18:1), for increased stability. Most car companies split the difference with a constant 14:1 ratio because this is the ratio that is required at high speeds.  This constant ratio is not optimal for low or mid speeds however. The Active steering in the 2011 BMW X3 Denver enables a different ratio for any given speed thereby optimizing stability.
