Controls for flexible multi functional driver information module

Abstract: The number of diverse and innovative technologies in the vehicles isincreasing. Along with them the risk for driver distraction and inattentionincrease, and the development of good user interface assume progressivelygreater importance. The purpose of this study was to examine where thecontrols for adaptive cruise control (ACC) and flexible trip computer/driverinformation should be placed and how the controls should be designed in orderto achieve good user interface. The work was done as an assignment for VolvoCar Corporation in Göteborg, Sweden.An information gathering phase started the study. Based on the collectedtheories and knowledge concepts were generated in order to evaluate drivers'attitudes towards different placements and designs of controls.The evaluation results show that the most preferred placement for ACCcontrols is a lever, and steering wheel for trip computer/driver informationcontrols. According to the movement expectations of the driver'sparticipating in the evaluation, the ACC should be activated, cancelled,resumed, and deactivated with a press on the top of the lever, towards thesteering wheel column. A movement of the lever upward should increase thespeed and a movement downward decrease the speed. The adjustment of time gapshould be completed with movements forward and towards the driver or with athumbwheel. If lever movements are applied, then movement forward should leadto a decrease of gap and towards the driver should increase it. Rotation of athumbwheel upwards should increase the time gap, and rotation downwardsshould decrease the gap.
