Electric Drive Armored Vehicle Real-time Simulation Research

In this paper the electric drive armored vehicle simulation system is build based on distributed simulation technology. The simulation system is set to three parts- week real-time part, strong real-time part and strict real-time part according to the difference of simulation step size. In weak real-time part, driver operation and vehicle dynamic real-time simulation is connected by CAN bus; In strong real-time part, engine, generator and battery are modeled and simulated by two sets of RT-LAB software, and connected by FlexRay bus; In strict real-time part, motor model and inverter model are simulated in FPGA and DSP hardware, and connected by parallel data bus.. The simulation results shows 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.
