PERFORMANCE OF THE DRIVER-VEHICLE SYSTEM IN CONNECTION WITH DEGRADATION IN STEERING AND WHEEL SUSPENSION COMPONENTS

PRESTANDA HOS SYSTEMET FAERARE-FORDON I SAMBAND MED SLITAGE AV STYR-OCH HJULUPPHAENGNINGSKOMPONENTER

A literature survey and experimental study were carried out in which the effects of degradation in steering and wheel suspension on driver-vehicle performance were studied. Twelve subjects drove nine passenger cars with degraded steering and wheel suspension components. The cars were driven at a speed of 70 km/h on a test track for nearly two hours. The track was relatively difficult and was composed of three parts; a straight course section, a double lane change manoeuvre section, and a serpentine manoeuvre section. The subjects were also asked to compare the vehicles from a traffic safety point of view. The results showed that although the driver-vehicle performance was not influenced by the degradation, this was often due to a great amount of compensation for the degradation on the part of the drivers. Normal degradation thus has no influence on traffic safety, even if the subjects have driven for a considerable period of time. The results are only valid, however, in situations in which the subjects are able to prepare themselves for the required driving tasks, not in situations where no such time is allowed. /TRRL/
