【Abstract】 About the powertrain of a series hybrid electric transit bus, one simulation model and its real time methodology were presented. Based on MATLAB/Simulink, the dSPACE controller and xPC target were integrated by the CAN technology. The former emulated the system control unit, and the latter personal computer ran the system model. At the same time, another personal computer monitored both of them and logged. On the novel real time platform, the model and its system controller of the SHEV powertrain system were simulated. The results testify that the real time simulation makes the system operation clearer, validates the real time control algorithm, and builds up the quick prototype of the vehicle control unit.更多还原
