| 摘 要： | 为了满足混合动力发动机扭矩管理控制策略的需要,建立了基于平均值模型和A/N—Te模型的发动机在线扭矩估算算法。在试验过程中,针对进气歧管压力响应滞后于节气门快速变化的问题,提出了预估算进气歧管压力估计进气流量的方法,消除了进气歧管内压力滞后的影响,完善了原始算法。通过台架试验得到发动机输出扭矩实测值,将实测扭矩与估算扭矩相比较,验证了算法的准确性。

| Abstract: | Based on the mean value model and-model,the estimation algorithm of on-board engine torque was developed in order to meet the requirement of HEV engine torque management strategy.For the problem of intake manifold pressure response lagging behind throttle fast changing,the pre-estimation algorithm of manifold absolute pressure was put forward.Comparing the estimated torque and the measured torque,the accuracy of algorithm was further verified. |
