Even if the sales of electric vehicles were increasing to solve environmental problems, short driving distances and inconvenient battery charging are the most important issues. Most car makers are trying to increase battery efficiency or extend the driving distance with new technic. DAS is one of the driveline systems used to increase the efficiency by disengaging the driving friction force from wheels to reducer and motor in a 4WD electric vehicle. But when the DAS disengage the driveline, the side and pinion gears in differential gear system rotate at a high speed and make gear noise severely. In this paper, through the developing a backlash measurement device for differential gear system, analyzing the operating condition and the noise generating mechanism, the differential gear noise are improved and backlash specifications and test methods related to the noise are set up successfully.
