The modular steering wheel multi-function unit made by RAFI GmbH & Co. KG is an innovative solution providing enhanced convenience and reliability of operation when driving. With up to 14 freely assignable functions you can handle nearly all vehicle functions without having to take the hands off the steering wheel or the eye off the road. The steering wheel multi-function unit excels by an ergonomic, logical and intuitively understandable arrangement of the controls.
Using the multi-function unit provides an “i-Pod feeling” at the steering wheel. The central element is a rotary wheel or rotary roll about which a closed ring with a rocking function (about the x and z axes) or 4 segmented single buttons are arranged. In the basic version, convenience systems such as automatic air conditioner, handsfree set or radio can be addressed directly via the steering wheel multi-function unit. RAFI offers an integrated or separate modular E-box for the integration of the multi-function unit into the data bus system of the vehicle (e.g. LIN, CAN, FlexRay), depending on the space available or the scope of functions implemented.
The RAFI steering wheel multi-function unit has an overall height of only about 12 mm including the necessary mechanical and electronic elements for the basic functions and thus offers maximum flexibility in steering wheel design. The system has a consistent modular structure and can therefore be used across several model series and equipment variants: Interfacing with various automotive data bus systems via the E-box, optional day/night design, variable number of detents of rotary wheel and roll, selectable key click, customer-specific materials for the controls as well as suitability for horn operation and steering wheel heating.
Hence, the new RAFI steering wheel multi-function unit fulfils all ergonomic, electronic and quality requirements of the automotive industry.
