MATHEMATICS, SIMULATION AND MODELLING
19 January 2011
IPG Automotive has announced its latest version of CarMaker 3.5, an open integration and testing platform designed to deliver more efficiency to the development process and open up new applications in the field of virtual test driving. The ‘SensoWheel’ steering simulator is the result of the integration of the precision-steering model by Pfeffer into the CarMaker simulation platform, and a realistic steering sensation comes from the steering torque in the driver-vehicle-road interface. This also makes changes in suspension kinematics and control interventions identifiable and perceptible.
The interaction between the mechanical model and the steering support unit ensures detailed modelling of steering characteristics, and the new steering model can be used for the evaluation of steering characteristics and effort, non-linear stationary performance, transient transmission performance, and closed-loop drive tests. It also aids the development of driver-assistance systems with active steering recommendation like lane keeping or parking. The user can select, configure and parameterise both the mechanical model and the steering assistance unit via the CarMaker 3.5 GUI.
