Test Bench Development Of Hybrid Electric Automatic Speed Regulation System

With the environment and energy crisis becoming more and more severe, energy conserving and environmental friendly automobile become our ultimate goal. Power system as the key spare parts becomes the hot point Now the largely used power systems among hybrid electric vehicles are THS of Toyota and IMA of Honda but due to several reasons they are not adopted in China. Electric Controlled Speed-Adjusting System is an especially designed system for HE V.Also the thesis introduces the construction, the selection and matching of hardware and software. The control system adopts the strong anti-interference, easy to learn and User-fiiendly PLC system. As to the DAQ, it adopts a special data-acquisition card and the bottom programs are compiled by LabVIEW to do the DAQ. The Display interface is made by FameVIEW, which displays the test procedure vividly.Through the test, the test board accomplishes the expected goals. After the analysis of the acquired data, it shows that the clutch in a low ratio can complete the shift swiftly and smoothly but when the ratio is high, the shifting is not that perfect Based on the analysis of the shifting process, it can conclude that the motor control technology become the most serious issue constraining the transmission. Though there are still some problems, after solving the ratio and motor control problem, the system will get a further optimization.
