| Summary: | 碩士 === 國立中央大學 === 機械工程研究所 === 95 === The purpose of this research is to understand the effect of unbalanced roads on driving performance of spinal cord injury (SCI) drivers. The author built a driving simulator, then proceeded several experiments. The uniaxial barometrical plate on which the driving simulator was settled could simulate the long-axial orientation of the simulated car when driving on inclination and braking. And a gravitation measuring plate settled on driving seat could measure the change of gravitation of subjects. Subjects were 10 normals and 3 SCIs with able upper limbs whose damage range was T12 to T4. Experiments included balance ability measuring, learning and virtual road events. The subjects'' driving behaviors were recorded during the experimental process, then analyzed statistically. The results show that SCI drivers still lost balance under larger fore inclination when they didn’t have hand supports even though the safe protection was applied. SCI''s stably car-control ability was inferior to Normal''s. In virtual road events experiment, there were significant interactions to gravitation position of subjects by up-down-grade, inclinations and groups.
