Samenvatting
Objective open and closed loop test procedures and subjective rating procedures on vehicle handling properties were developed and used in two experiments. A visual occlusion technique with a fixed looking time of 0.5 s was used to find a relation between the number of looks needed and driver workload was related to vehicle properties. Results indicate that occlusion time varies consistently with workload and handling properties. Special interest was given to the spectral analysis of driver steering inputs.
