摘要
分析了并联式混合动力汽车的能量流动情况,建立了便于进行扭矩分配计算的驱动系统简化模型。将电池充放电过程中消耗的能量等效为一定的油耗,以最少等效油耗为目标函数,建立了实时控制策略。针对FUDS驾驶循环,计算得到了最少油耗的实时扭矩分配方案,结果表明,该实时控制策略能有效的降低车辆的燃油消耗,优化发动机的工作点。
Based on the analyzing of the energy flow principles of parallel hybrid electric vehicles (PHEV),a simplified power train model is proposed in this paper.With this model,it is convenient to deal with the torque split.In this paper,the charge/discharge process of the battery is considered equivalent to fuel consumption process.The proposed optimal control strategy is targeted for the minimal equivalent fuel consumption.The torque split scheme for the FUDS drive cycle with minimal equivalent fuel consumption is obtained and the results indicate that the optimal real-time control strategy could improve the fuel economy and optimize the operation points of engine.
