Vehicle dynamics testing

With complete systems for exact measurements of longitudinal and transverse dynamics

Intensive vehicle dynamics tests play an essential part in vehicle development. Whether the focus is on sports performance or comfort: tuning of the chassis and control systems is a decisive factor in achieving the desired characteristics for the vehicle. In this way, automobile manufacturers can exploit unrivaled opportunities to stand out radically from their competitors. 

However, this must always go hand in hand with safety. Passing the ISO standard tests for stable driving behavior is the fundamental requirement for developing a unique driving experience and a feeling of safety while driving – for passenger vehicles on normal roads as well as racing cars in motorsport. 

Control systems such as ABS and ESC must be correctly tuned to ensure stable driving behavior if the vehicle suddenly changes direction. Vehicle-specific design requires precise characterization of longitudinal and transverse dynamics based on measurements of the sideslip and drift angles. Especially in motorsport, measurements of these motion parameters for vehicle dynamics can be the key to critical competitive edge.
