Abstract: The comfort of a clutch can not be measured by now, theres no proper test method or product. Aiming at this problem, “a couple compare” method was used in the test plane. Two same type clutches were fixed on the plane, which were tested by professional drivers. The objective parameters were measured by some sensors, and there were compared with the drivers subjective scores. The corresponding relationship between objective parameters and subjective feelings was built with curve fitting. The error between computed score and subjective score is less than 10%. The results indicate that the important influence parameters for clutches are the maximum, minimum and final pedal force.
Key words: clutch; comfort; subjective test; curve fitting
