Abstract: To ensure the safe and stable operation of electric forklifts and accurate fault diagnosis analysis, this paper focuses on the vehicle control unit (VCU) of electric forklifts and designs a comprehensive power up and down strategy alongside a hierarchical fault diagnosis system. Test results demonstrate that the power up and down strategy ensures stable system operation with control logic meeting requirements, while the fault diagnosis module achieves 100% of the targets in modelin-the-loop (MIL) testing. In real-vehicle tests, the system achieves a fault identification accuracy of over 98% with rapid response. This study effectively enhances the operational safety and maintenance efficiency of electric forklifts, providing a valuable reference for the optimization of industrial vehicle systems.
