Drivers’ Assessment of Driving a 32 Meter A-double with and without full automation in a moving base simulator

Peter Nilsson

In situations where LongCombination Vehicles can be challenging to maneuver, drivers could be supportedthrough automated driving systems. A safe way to assess prototypes of suchsystems is to take advantage of driving simulators. This study assessed therealism of driving a 32m and 80 ton A-double in an advanced moving-base drivingsimulator, with and without full automation. The conclusions were that the realism of the roadenvironment, vehicle suspension, vibrations, steering-wheel feeling and themaneuverability/drivability was on adequate levels but would benefit of moretuning. More urgent were adjustments of braking, acceleration, level of enginesound and improved view in the right-hand side mirror. Two tested automateddriving systems were appreciated for their lane positioning and drivingperformance, with a slight preference of the more advanced system for lateralcontrol. Negative comments referred to harsh decelerations before curves. Thesubjective assessment was much in correlation with the objective data from thesame simulator experiment.
