Method, device and system for evaluating characteristic curve of train transmission control unit and medium

The embodiment of the invention discloses a method, device and system for evaluating a characteristic curve of a train transmission control unit and a medium, and the method comprises the steps: obtaining an actual characteristic point of the train transmission control unit in a testing process, and drawing an actual characteristic curve based on the actual characteristic point; determining a smoothness parameter based on the actual characteristic point and the actual characteristic curve; determining a difference degree parameter based on the actual characteristic point and a preset standard characteristic curve; and determining the quality of the actual characteristic curve based on the smoothness parameter and the difference parameter, the smaller the quality is, the more the corresponding actual characteristic curve meets the preset design requirement. According to the scheme, the advantages and disadvantages of the actual characteristic curve can be judged from multiple angles. 本发明实施例公开了一种列车传动控制单元特性曲线评估方
