Active steering (AL) and rear axle slip angle control (HSR)

The combination of active steering (AL) and rear axle slip angle control (HSR) is referred to as INTEGRAL ACTIVE STEERING: OPTIONAL EQUIPMENT 2VH .

Integral Active Steering can influence the steering angle set by the driver without affecting the steering wheel angle. This means that for the first time the steering angle is specified at the front and rear axle independently of the driver. This leads to the following advantages:

• The variable steering gear ratio optimized for every driving speed means that on the whole the vehicle can be driven with a more sport-oriented style and more accurately. The amount of effort required by the driver is reduced, thus making an additional contribution to active safety.
• At lower driving speed, very agile driving characteristics set in. The turning circle of the vehicle is reduced.
• At higher driving speed, effortless, comfortable driving characteristics set in. The vehicle seems to be directly "linked".

This document describes the function of the Integral Active Steering with rear axle slip angle control. The active steering function on the front axle is described in detail in the vehicle engineering diagnosis 320103001.
