Direct Adaptive Steering™ (DAS) is the world's first production steer-by-wire system, providing new levels of control, precision and adaptability. The system uses advanced electronics to streamline the steering mechanism for a more precise feeling behind the wheel.
Developed after more than 10 years of research, Direct Adaptive Steering™ allows independent control of the Q50's tire angle and steering inputs, transmitting the driver's intentions to the wheels faster than a mechanical system. This increases the direct driving performance feel by quickly and intelligently communicating road surface feedback to the driver. Over uneven roads, for example, this moderates the need for constant, subtle adjustment, imparting a commanding feeling while helping shield the driver from excessive road vibrations.
While systems such as Direct Adaptive Steering™ will be critical in future autonomous vehicle designs, Infiniti Q50 owners are realizing a real benefit today in the system's ability to customize steering settings according the driver preference and road conditions. The system allows the driver to change both steering effort and the steering gear ratio.
