Hybrid Vehicle Engine Electronic Control Unit Detection System Based on Dynamic Simulation Technology
The electronic control unit(ECU)is an important part of the hybrid vehicle engine,which has a direct impact on the driving performance of the engine and hybrid vehicle.In order to ensure the normal operation of the ECU,the dynamic simulation technology is used to optimize the design of the ECU detection system of the hybrid vehicle engine.Modify the temperature,speed and other sensor equipment and signal processor equipment,adjust the connection mode of the system circuit,and achieve the optimization of the hardware system.The dynamic simulation technology is used to simulate the electric control process of the hybrid vehicle en-gine,and the test standard of the system is set according to the operation characteristics of the electronic control unit under different fault types.The output signal of the ECU is collected,the signal features are extracted from the time domain and frequency domain,and the status,fault type and fault location of the ECU are determined by the feature matching to realize the ECU detection function of the system.Based on three operating scenarios of the hybrid vehicle engine,the system test results show that compared with the traditional detection system,the missed and false detection rates of the optimized design system are reduced by 2.59％and 2.05％re-spectively,which proves that the optimized design system has good detection function.
