英文摘要： Automobile dynamic properties are evaluated for symbolic parameters of automobile comprehensive performance, directly related to environmental protection and energy use and so on. The mesuring key for power performance and fuel economy of automobile is how to measure the automobile engine output power and get accurate measurement data quickly and effectively. At present, bottleneck problems of automobile engine power are faced with poor reliability of measurement data, poor accurately of road resistance, measuring complex, low efficiency and so on. In this project, single roller without disassembly measuring system is built. Jiangling baodian 2007 as the automotive model, the acquisition and measurment methods for signal of the automobile chassis output power by single roller without disassembly measuring system are studied. The measurment methods of power consumption by single roller without disassembly measuring system are studied.The signal acquisition methods of automobile transmission loss power by single roller without disassembly measuring system is studied. On this basis and according to theoretical analysis, the engine output power mathematical model by single roller without disassembly measuring system is established. The accuracy and validity of model is validated by output power engine bench experime
