Software simulation, the advantage is that it can be implemented in the forward design stage. Through software simulation, it is verified whether the wiring harness assembly is reasonable, whether the topology structure of the vehicle wiring harness is suitable, whether the power distribution principle design and electrical device layout are reasonable, etc. However, the software simulation is simulated by the calculated parameters, which cannot realize the test and verification of the actual vehicle conditions and various operating conditions of the actual vehicle.
The bench test is generally carried out at the stage of electrical device C sample. At this time, the function of the electrical device is complete, the state is close to the mass production sample, the performance is relatively stable, and the test result is highly reliable. On the electrical bench, the bench simulates the working conditions of the actual vehicle electrical appliances to test the actual parts, which has the advantages of high reliability of the test results and close to the actual vehicle working conditions, but the wiring harness layout cannot be completed on the bench. Check, some real vehicle conditions cannot be simulated (such as the current distribution of the grounding point of the whole vehicle).
