This release of the VehicleDynamics Library provides considerable enhancements compared to earlier versions:

• Improved library structure with enhanced set of experiment templates and components.

• The UsersGuide is improved and distributed printed and as pdf.

• The examples are extended with steer-by-wire application, control of active chassis systems and more.

• The driver models are improved and contain perception, planning and tracking tasks as well as physical driver-vehicle interfaces.

• A PowerTrain level is introduced for easier inclusion of non-conventional drives such as hybrids.

• A new tyre model with physical extrapolation of pure slip data is included.

• Dashboard model allow for driver-vehicle information exchange.

Welcome to visit our exhibition booth at the 5^th International Modelica Conference at Arsenal Research in Vienna, Austria on September 4 - 5, 2006, where our staff will present our model library products and consulting services.
