Vehicle Dynamics Control
 Driving Guidance is the area of automotive ICT. Electronics are put to use for information, entertainment and driver support and will eventually take over driving tasks. The goal is to improve traffic flow, safety and the environment.
Today, advanced chassis control systems use motion based sensing of the vehicle body and wheels as input to counteract undesirable vehicle motions. Directly measuring the forces between the tire and the road has not yet been possible. New sensing techniques, including virtual sensors, allow these forces to be measured directly, so that preventive actions can be taken earlier and more accurately to improve vehicle handling and stability. New integral chassis control strategies will be developed for a range of situations and vehicles.

Ioniqa
MagnethoRheological Fluids
MagnethoRheological Fluids (MRFs) are suspensions of very small magnetic particles in a fluid. The viscosity of MRFs can be changed by applying a magnetic field.
This can a.o. be used to adjust the properties of shock absorbers, or the energy absorption of a crashworthiness system.
Ioniqa has developed a new and patented technology to use liquid salts as a solvent base. This lowers the cost and creates a far bigger range to tune the properties. From now on MRFs are suited for a broad field of applications.

TNO Vehicle State Estimator
TNO created a comprehensive vehicle model using input from standard ESP sensors in the car. Their information is fused to build new ‘virtual’ sensors to complete the vehicle model with signals that cannot be measured. The system has been tested to match reality in a large variety of drive situations. The Vehicle State Estimator brings chassis control to a new level that will have great value for new and improved active safety systems.

Actiflow
The Actiflow System
The thin layer of air bet ween the car and the surrounding air has a big influence on aerodynamics. Actiflow found a way to influence this layer of air by using a pump to exctract air from under the car.
Actiflow tactically feeds this air into the wake of the car to reduce turbulences and hence CO2 emission. The air can also be used for extra cooling on specific places or, in the ‘sport’ mode, to increase the downforce. The system has been adopted by Ferrari.
