参数样条函数 meaning in Chinese

parametric spline function

In the designing of priority for the transmission ratio , the usage of gear ' s attest on transmission ration should be considered ; the average value is set as the evolution aim of the loss of driving power and the useful effectiveness . a simplified fuel - consumed economically model is used to simulate the fuel consumption while the automobile is in motion
在变速器传动比优化设计中考虑档位使用率对变速器传动比的影响，采用驱动功率损失率和有效效率利用率的加权平均值作为评价指标，用参数样条函数模拟车速状态下的燃油消耗量，提出了按变速器传动比的使用率来确定汽车的加速和等速的比例，并将其作为实际工况来确定汽车的实际燃油消耗率。
