Abstract: In order to simplify the configuration process of the transmission control unit (TCU) and provide a flexible way to manage and modify TCU parameters. This paper presents a heavy-duty hydraulic automatic TCU configuration tool based on Python and Kvaser Leaf. By using Python programming language and Kvaser Leaf interface, TCU can be directly controlled and configured through controller area network (CAN) calibration protocol (CCP). The tool configues user-friendly profiles so that users can easily browse and modify TCU parameters. The experimental results show that the tool has high efficiency and reliability in configuring TCU, can greatly improve the efficiency of configuration work, and is easy to expand and low cost.
