4WD 차량의 변속기 동력계를 이용한 동력 성능시험

The evaluation of a powertrain system is one of the major issues to represent the overall vehicle performance. The test can be performed either as a part unit in a laboratory or as a vehicle on the proving ground. However, many disadvantages exist in the actual vehicle test - cost, danger, environment, etc. In this paper, a reliable test environment in a laboratory for the evaluation of the powertrain system is suggested. All parts related to the vehicle running performance are modularized and configured with 4 wheel drive transmission dynamometer. Then, the accelerating test, based on the actual vehicle test, is performed with the transmission dynamometer. The test results are compared to the actual vehicle test data. The test environment suggested in this research represents the performance of powertrain system well.
