Innovative Solutions

The TSMaster development platform assists you with analysis, simulation, testing, calibration, diagnostics, and brushing services. Many free and convenient features are available.


Quick Response

Our team is dynamic and open to discussion. We can assist users in solving engineering problems, building customized services, and streamlining complex and time-consuming project processes.

Technology Case

HIL Real-Time Simulation

Using TSMaster to build vehicle controller HIL real-time simulation from scratch, with the TOSUN hardware interface module can achieve the highest performance. Based on the real-time nature of HIL simulation, we can then perform real-time simulation by manipulating the bus data sending method.

CCP / XCP Calibration

CCP/XCP Calibration with TSMaster. It is an indispensable process in the development of the vehicle and ECU, and plays a vital role in optimizing the performance of the vehicle and ECU.

UDS Diagnostic Services

The diagnostic feature allow user to build  their own request and response according to their needs. The diagnostic transport layer type supports CAN/CANFD/LIN, and in the future will support automotive Ethernet and FlexRay, as well as multiple diagnostic modules at the same time.
