Ergonomic Considerations of Clutch Pedal Design for a Heavy Commercial Vehicle

This paper gives focus on the ergonomic design of the clutch pedal. The parameters considered includes height of clutch actuation point (CAP) from cabin floor mat, lateral position from steering column and engine tunnel, size and angle of foot pad, texture design of rubber cover, maximum pedal travel packaging considering variants, force, and modulation requirements. Development of clutch pedal assembly is carried out by considering collected anthropometric data for large population range. With a set of questionnaire asked to number of drivers on their habit of keeping foot on the clutch pedal which causes fatigue and phenomena of clutch riding (results in wear of clutch disc).
