Key Words : High-Performance Vehicle (고성능 차량), Affective Satisfaction (감성 만족도), Subjective Evaluation (주관적

In the automotive industry, emotional quality in vehicle development is an important development
factor that determines vehicle quality along with basic performance. Emotional quality can be divided
into dynamic and static items depending on whether they are driven or not. Driving emotion is included
in the dynamic category. Driving emotion has a comprehensive effect on various factors, including the
vehicle's powertrain characteristics, handling, ride comfort, braking, and noise vibration. In this study, a
subjective evaluation was conducted to derive a major factor in emotional satisfaction during sports
driving under racetrack conditions. The assessment has been performed on Korea International Circuit,
using three cars with four skilled drivers for D-segment sports sedans. The assessment items
consisted of powertrain, R&H, and NVH categories, and each item and overall satisfaction were
assessed using the rating method. Fig. 1 represents the evaluation track and the evaluation scene.
T1~T9 shown on the track indicates the position of each assessment item. First, the characteristics of
powertrain were evaluated for driveaway acceleration performance and gear shift quality. And from the
R&H aspect, steering response, maneuverability, etc. were evaluated. Finally, from the NVH
perspective, the main NVH items that can occur during racetrack driving were evaluated, such as the
engine sound at acceleration and deceleration, gear shift sounds, and the tire friction sound during the
drift. The results of the evaluation showed that affective satisfaction was more affected by sound than
by the handling characteristics.
