Development of a Vehicle Laboratory to Investigate Driver Comfort from Physical Measurements

A vehicle laboratory has been developed in which the vehicle operator's posture, pressure distribution, muscle activity, and comfort can be measured while driving on the highway. This instrumented vehicle uses video camera, pressure mats, electromyography, and questionnaires to make these measurements. There is an on-board PC486 to record the data fro later off-line analysis. These data are useful for developing design criteria for seating comfort as well as investigating the real-life position that the operator sits in the vehicle package while driving the vehicle on the highway.
