The ZC.XuanWu Calibration Tool is a general-purpose measurement and calibration protocol tool based on ASAM standards, supporting multiple communication protocols (such as CAN, CANFD, Ethernet, etc.). It is specifically designed for online calibration, data collection, and debugging of automotive electronic control units (ECUs). Its core functions include:

Real-time Data Collection: Supports both Polling (cyclic query) and DAQ (data acquisition) modes.Online Parameter Calibration: Dynamically adjusts ECU parameters that take effect in real-time, supporting block calibration and 2D array calibration.Flash Programming: Generates hex files from calibrated parameters, which can be programmed and stored into the ECU's Flash memory to ensure persistent effectiveness.Multi-Protocol Compatibility: Supports transport layers such as XCP-on-CAN, XCP-on-CANFD, and XCP-on-Ethernet, adapting to different vehicle network environments.

With the acceleration of automotive electrification and intelligentization, the functional complexity of Electronic Control Units (ECUs) has grown exponentially. In the early 21st century, traditional automotive calibration gradually revealed the following limitations:

Bandwidth Bottleneck: Supported only CAN bus with a maximum theoretical bandwidth of 1 Mbps, failing to meet high-frequency data acquisition requirements (e.g., motor speed, battery cell voltage).

Protocol Rigidity: Incompatible with emerging in-vehicle networks like CAN FD and Ethernet, constraining the development of multi-domain controllers (e.g., domain controllers, central computing platforms).

High Resource Consumption: Required pre-allocated fixed memory blocks (DAQ List) in ECUs, resulting in low memory utilization, particularly problematic for small-memory MCUs.

Limited Functionality: Lacked advanced features such as dynamic calibration and secure access, making it difficult to comply with ISO 26262 functional safety and cybersecurity requirements.

ZC.XuanWu Calibration Tool addresses these challenges by:Multi-bus compatibility: Adapting to various bus types (CAN/CAN FD/Ethernet).Mainstream hardware support: Seamless integration with industry-standard devices.Comprehensive measurement & calibration: Supporting diverse calibration types.User-friendly GUI: Featuring intuitive graphical interfaces for simplified operations.Customized solutions: Fully meeting customer requirements across scenarios.
