To cope with the quest to improve the fuel economy and vehicle performance, Continuously VariaTransmission with changing the speed ratio between minimum and maximum ratio by infinite step, is more efficient than conventional multi-ratio transmission.<br/>
In this paper, to investigate a specific CVT shift ratio diagram and CVT shift characteristics, CVT vehicle was tested on the proving ground and chassis dynamometer. The test results are as follows; CVT can obtain the excellent vehicle performance and fuel economy by changing the shift ratio by infinite step, without rapid change of engine revolution and driving force. And CVT can set up a special shift range that obtains not only the engine brake effect but also the maximum speed driving.<br/>
