During the early phase of vehicle development, one of the key design attributes to consider is the inner comfort for occupants. Internal spaciousness is the pillar that is responsible for user's comfort and make into customer comfort needs in engineer metrics. Therefore, it is one of the key requirements to be considered during the vehicle design.
Certain internal vehicle characteristics such as the size of shoulder room and the knee clearance are engineer metrics that influence the perception of comfort for occupants. One specific characteristic influencing satisfaction is the headroom, which is the subject of this paper.
The objective of this project is to analyze the relationship between the vehicle headroom with the driver satisfaction under real world driving conditions, based on research, statistical data analysis and dynamic clinics. Other influences, such as the position of the driver in the seat was also studied and captured in this paper.
