Axle is H30, the longitudinal axis be H17 coordinate system in indicate the related datas of these 7 existing automobiles respectively, obtain data point A,
Data point B, data point C, data point D, data point E, data point F and data point G.Then, based on these data
Point A, data point B, data point C, data point D, data point E, data point F and data point G, simulate Linear Quasi
Zygonema, it expresses function (the i.e. first relation formula) is H17=(A2 × H30+B2) ± C2；Wherein, A2, B2 and
C2 is the constant that the Fitting Calculation goes out.In implementing, the grand instrument write can utilized, extract the design ginseng in data base
Number utilizes method of least square, and the optimum linear function found in statistical data by the quadratic sum minimizing error is mated.
After in data base, the capacity of data is enriched constantly and accumulated, due to the passage in age time, the new design style caused, new skill
Art application, new legislation require and the renewal (overall height lifting etc.) of crowd's physiology size statistic data, this empirical equation
Need interim being updated according to latest data storehouse state.
Exemplary, the first relation formula is: H17=(A2 × H30+B2) ± C2.Wherein, A2, B2 and C2 are for intending
Add up to the constant calculated.
It is enumerated above the instantiation of fitting algorithm and separation vehicle, it will be appreciated by those of skill in the art that the present invention is also
