The evaluations of ride comfort in gear shifting have been known as one of the dominant factors for vehicle quality assessment. However, those factors have not been assessed and analyzed objectively in-depth in conjunction and integration with general ride and handling parameters. In recent, the criteria set by customer have changed on account of heightened expectations, resulting in a growing demand for enhanced ride comfort. the quality of gear shifting experienced by a customer is evaluated subjectively on road leads to difficulty in arriving inferences and taking decisions due to variation in responses of people on the same situation.
This study is involved the process of conversion from subjective to objective assessment on gear shifting quality by identifying the objective parameters for contributing the quality of gear shifting feel.
Measuring and analyzing those parameters like lever travel, lever effort, and noise while shifting during dynamic condition at vehicle level on road with the use of digital data capturing by data acquisition from the sensors like Strain gauge, Accelerometer and potentiometers. The captured data has been analyzed and corelated to subjective ratings between intended vehicles.
The same experiment has done at lab with the use of dynamometer and robotic arms, data are captured and correlated with on road dynamic measurement. As a result, the comparative report and experimental results are discussed in terms of gear shifting quality by triangular approach as follows: subjective evaluation - objective evaluation @ on road – Objective evaluation @ lab.
