Modern steering systems take over a variety of vehicle safety and comfort functions. In addition to the basic requirements for functionality and steering behavior subjective quality characteristics such as noise and vibration and the haptic feedback to the driver have a major impact on the perceived quality of the steering system.
Our extremely quiet and low vibration actuators and testing systems enable reproducible simulation of driver functions and road & vehicle inputs acting on a steering system to experimentally develop, evaluate and validate NVH metrics and to experimentally verify EPS functions in order to achieve performance goals over the customer-equivalent useful life of a steering system.
