Fig. 4 is the exemplary schematic representation being fitted according to H30 and H17 of the present invention to multiple existing automotive types.
As shown in figure 4, acquiring the H30 numerical value and H17 numerical value of the existing automobile of 7 a variety of models first, and it is in horizontal axis
Indicate the related datas of this 7 existing automobiles respectively in H30, the coordinate system that the longitudinal axis is H17, obtain data point A, data point B,
Data point C, data point D, data point E, data point F and data point G.Then, point A, data point B, data point based on these data
C, data point D, data point E, data point F and data point G, fit Linear Quasi zygonema, and expression function is H17=(A1 × H30
+B1)+C1；Wherein, A1, B1 and C1 are the constant that the Fitting Calculation goes out, which is the second relation formula.Specific real
, can be using the macro tool write in existing, the design parameter extracted in database utilizes least square method, is missed by minimizing
The optimum linear function that the quadratic sum of difference is found in statistical data is matched.The capacity of data is enriched constantly product in the database
After tired, due to the passage in age time, caused new design style, New technical use, new legislation requires and crowd's physiology ruler
The update (whole height promotion etc.) of very little statistical data, this empirical equation needs interim foundation latest data storehouse state to carry out
It updates.
Then, the H30 determined in step 101 is substituted into the second relation formula, obtains the reference value of H17.
Preferably, H17=687.36+C1；It is highly preferred that finally the reference value of determining H17 is 666.6.

With reference to automotive type steering wheel hub with heel point a longitudinal separation value be fitted, with obtain steering wheel hub and heel point front and back away from
From the first relation formula between parameter and reference point for the design and the vertical range parameter of heel point.
In one embodiment, with reference to automotive type screening conditions, comprising: the reference automotive type filtered out, side
It is less than predetermined threshold to the difference of the vertical range and reference value of disk center and heel point.
For example, when determining the reference value of vertical range of steering wheel hub and heel point in a step 102 is 666.6, it is false
Determining predetermined threshold can be 30.At this point, the reference automotive type filtered out, the vertical range of steering wheel hub and heel point is answered
It should be located within range [636.6,696.6].
For another example, when determining the reference value of vertical range of steering wheel hub and heel point in a step 102 is 666.6,
It is assumed that predetermined threshold can be 40.At this point, the reference automotive type filtered out, the vertical range of steering wheel hub and heel point
It should be located within range [626.6,706.6].
Preferably, multiple to belong to identical separation vehicle with reference to automotive type and automotive type to be developed.Separation vehicle packet
It includes at least one of following: orthodox car, hybrid vehicle, electric car, minicar, compact car, compact sedan, medium-sized
Vehicle, medium-and-large-sized vehicle, luxurious car, multipurpose automobile MPV, sport utility vehicle or sport car, etc..
The schematic diagram for referring to automotive type is determined according to Fig. 5 the present invention is based on the reference value of H17.
As shown in figure 5, when the reference value of the vertical range of steering wheel hub and heel point is 666.6, it is assumed that predetermined threshold
It can be 30.So, the reference automotive type filtered out, steering wheel hub and heel point vertical distance range be [636.6,
696.6].Preferably, further constraint item of the threshold value of H30 to refer to automotive type as screening can also be further set
Part.For example, the threshold value of H30 is 350, it is meant that the H30 of the reference automotive type filtered out is not greater than 350.It can by Fig. 5
See, automotive type D and automotive type E are located at the range intervals, therefore can be used as with reference to automotive type；Automotive type A, automobile
Vehicle B and automotive type C is not located at the range intervals, therefore cannot be as with reference to automotive type.
After determining with reference to automotive type, to the vertical range of multiple reference point for the design with reference to automotive type and heel point
Value is fitted with multiple steering wheel hubs with reference to automotive type and heel point longitudinal separation value, to obtain steering wheel hub and heel
The first relation formula between point longitudinal separation parameter and reference point for the design and the vertical range parameter of heel point, specifically includes:
Vertical range value to multiple reference point for the design with reference to automotive type and heel point and multiple with reference to automotive type
Steering wheel hub and heel point longitudinal separation value carry out linear least square fitting；Or

Steering wheel hub and heel point longitudinal separation value carry out nonlinear least square fitting.
Fig. 6 is according to the present invention to the fit procedure exemplary schematic representation of multiple H30 and L11 with reference to automotive type.
As shown in fig. 6, acquiring the H30 numerical value and L11 numerical value of 7 existing automobiles with reference to automotive type first, and in cross
Axis is H30, the longitudinal axis is the related data for indicating this 7 existing automobiles in the coordinate system of L11 respectively, obtains data point A, data
Point B, data point C, data point D, data point E, data point F and data point G.Then, point A, data point B, number based on these data
Strong point C, data point D, data point E, data point F and data point G, fit Linear Quasi zygonema, and expression function is L11=(A2
× H30+B2)+C2, as the first relation formula；Wherein, A2, B2 and C2 are the constant that the Fitting Calculation goes out.In the specific implementation, can
With using the macro tool write, the design parameter extracted in database utilizes least square method, by minimizing the flat of error
Side and the optimum linear function found in statistical data are matched.The capacity of data is enriched constantly after accumulation in the database,
Due to the passage in age time, caused new design style, New technical use, new legislation requires and crowd's physiology size statistic
The update (whole height promotion etc.) of data, this empirical equation needs interim foundation latest data storehouse state to be updated.
It is exemplary, the first relation formula are as follows: L11=(A2 × H30+B2)+C2.Wherein, A2, B2 and C2 are the Fitting Calculation
Constant out.
The specific example of fitting algorithm and separation vehicle is enumerated above, it will be appreciated by those of skill in the art that this hair
Bright to use other fitting algorithms, embodiment of the present invention is to this and is not limited.
Step 104: vertical range value and the first relation formula based on reference point for the design and heel point determine automobile to be developed
The steering wheel hub of vehicle and heel point longitudinal separation value.
Herein, the vertical range value of the reference point for the design determined in step 101 and heel point is substituted into the first relation formula,
So that it is determined that going out the steering wheel hub and heel point longitudinal separation value of exploitation automotive type.Preferably, L11=396.624+C2；More
Preferably, L11=364.
As it can be seen that embodiment of the present invention fits the second relation formula, and root based on the data of a large amount of existing automotive types
Determine H17 value then to recycle the reference value to screen from existing automotive type as reference value according to the second relation formula
Automotive type is referred to out, to be used for subsequent further fitting operation, so that the present invention can more accurately utilize available data,
The screening conditions of quadratic fit are determined by once fitting result, can reduce the complexity of fit operation, improve design
Efficiency, and ensure that data precision.
