The invention belongs to the technical field of hybrid power vehicles, and particularly relates to a hybrid power vehicle parameter calibration method and device. The method comprises the steps of firstly, establishing a whole vehicle simulation model comprising an energy consumption model according to the actual situation of a whole vehicle, the energy consumption model comprises a theoretical oil consumption model and a theoretical power consumption model, and power consumption or oil consumption is adopted for characterization, then obtaining whole vehicle working condition data and a feasible region of to-be-calibrated parameters, inputting the whole vehicle working condition data into the whole vehicle simulation model, traversing in the feasible region of the to-be-calibrated parameter, and finding the value of the to-be-calibrated parameter corresponding to the result of the lowest energy consumption value of the energy consumption model as the optimal calibration parameter under the whole vehicle working condition. According to the method, the physical quantities with two different dimensions are processed into the physical quantity with one dimension, so that the specific energy consumption is clearly and clearly judged, the energy consumption values corresponding to the to-be-calibrated parameters with different values can be accurately judged, and the calibration effect is improved.

    本发明属于混合动力车辆技术领域,具体涉及一种混合动力车辆参数标定方法及装置。该方法首先根据整车实际情况搭建包括能耗模型的整车仿真模型,能耗模型包括理论油耗模型和理论电耗模型,采用电耗或者油耗表征:然后获取整车工况数据和待标定参数的可行域,将整车工况数据输入至整车仿真模型中,在待标定参数的可行域内进行遍历,找到能耗模型的能耗值最低的结果对应的待标定参数的取值作为该整车工况下的最佳标定参数。本发明将两个不同量纲的物理量处理为一种量纲的物理量,从而对具体能耗的多少有了清楚明确的判断,可准确判断不同取值的待标定参数对应的能耗值大小,提高了标定效果。
