Due to the more demanding quality requirements for the vehicle manipulating comfort imposed by the market in recent years, the driver's feeling during gear shifting has become very important in the design stage of the shifting systems. This paper combines the ergonomics theory with the vehicle shifting device, and expounds the application and practice of the ergonomics in the innovative design of the vehicle shifting device. Firstly, GSA analysis system is used to pre-evaluate the static and dynamic shifting performance of the whole vehicle, and analyzes the shifting device of the vehicle transmission according to ergonomics theory. And then the corresponding improvement measures are put forward for the existing defects in the shifting device. Finally, the post-test analysis is carried out to verify the effectiveness in improving the driving experience of the whole vehicle, and ultimately enhance the competitiveness of the studied shifting device in the vehicle industry.
