Description
Summary:Vehicle drivability is defined as the smoothness of a vehicle’s operation at the will of a driver under all driving conditions. Currently, drivability evaluation is conducted through a subjective ratings-based test standard which is derived from established procedures. Human subjective rating can be inconsistent due to physical health conditions and individual preferences. This study is conducted to determine the possibility of using longitudinal acceleration to arrange an objective drivability assessment. Vehicle evaluation is conducted to determine the subjective vehicle drivability ratings of four drivability expert evaluators. A test vehicle was evaluated under different acceleration conditions to determine a subjective drivability rating. Vehicle low speed passing acceleration during pedal tip in is measured. A relationship between low speed passing acceleration and subjective drivability rating is established. An objective drivability assessment tool is successfully arranged using this relationship. A drivability rating can be generated using the tools, without the need for subjective evaluation by expert evaluators.
