Research on auto shift information acquisition system based on MCU C8051F120

摘要

A new set of self-made car shifting information acquisition system is introduced. By means of acquisition of multi-sensors, and with the improved recursive average filter method, a test platform including a mechanical device, information collection module and the host computer that was setted up in this paper. The system can realize real-time data acquisition for shift force, shift route, choosing grade route, pedal force and pedal route, meanwhile, using MATLAB to carry on the data analysis, with the image and the curve showing the spatial position of the shift lever, the movement trajectory of the clutch pedal and the situation of the certain components under the shifting force in the process of shifting. Real vehicle test proves that the automobile gear shifting information acquisition system is accurate and reliable, and it has important significance for the objective evaluation of the shift operation quality.
