How to quickly diagnose has always been a difficulty of chassis engineers when optimizing automobile driveline. In order to make the main direction of optimization work more clearly, it is required to determine exactly the power loss distribution of automobile driveline. In this study, a method used for measuring power loss distribution of mini-car driveline was proposed based on detailed research of the structure and working principle of mini-car driveline. Through measuring the internal resistance of mini-car driveline on a chassis dynamometer in different conditions, the power loss of each driveline component can be quantified combined with mathematical model proposed by us for power loss and the complete feature of the whole driveline can be obtained with this method. And best of all, the components that have potential to improve become evident which has very important theoretical and practical significance to optimization work for mini-car driveline. The research we have done suggests that this method used in our study is simple and effective and can greatly enhance the efficiency of optimization work for mini-car driveline.
