【Abstract】 Methods of simulation of vehicle powertrain’s performance are studied. Three simulation strategies are put forward and discussed in detail, viz the back-facing approach, forward-facing approach and bidirectional-facing approach. Their calculation flow charts are shown respectively. A simplified vehicle powertrain model, the powertrain components’ model and driver model are put forward accordingly. The performance of BJD6100-EV transit bus is simulated by different simulation methods, the calculation results are found to be close to the experimental results. The simulation methods can be used to simulate the energy economy, power performance and driving characteristics of vehicle powertrains.更多还原
