The assessment of a vehicle’s dynamical properties is related to three essential motions:
longitudinal motion (driving and braking),
lateral motion (guidance and steering),
vertical motion (suspension and damping).
These three motions of a vehicle are more or less decoupled, so that the assessment criteria can be formulated separately for each motion. Of course, coupled criteria can be developed if necessary. But the more sophisticated criteria have to meet also the vehicle’s rating by test drivers. Thus, the question of a mathematical formulation of assessment criteria is more difficult and can often be answered empirically only. Sometimes an interdisciplinary approach is helpful taking into account ergonomical knowledge.
