Abstract: The electric drive armored vehicle simulation system was built based on distributed simulation technology, according to the difference of simulation step size, the simulation system was set to three parts: week real-time simulation part, strong real-time simulation part and strict real-time simulation part. In week real-time simulation part, the communication between driver operation and vehicle dynamic simulation was connected by CAN bus; In strong real-time simulation part, engine, generator and battery were modeled and simulated by two sets of RT-LAB software, and the communication was connected by FlexRay bus; In strict real-time simulation part, motor model and inverter model were simulated in FPGA and DSP hardware, and the communication was connected by parallel data bus. The real-time characteristic of the simulation system was analyzed according to computation real-time performance, communication real-time performance and scheduler real-time performance. The simulation results show that this simulation system has a good performance at the simulation of vehicle capability, electric drive system and part capability, as well as the real-time demand is needed.
