The invention discloses a method and a device for determining a vertical distance between a steering wheel center and a heel point. The method comprises the following steps: determining the design reference point and the heel point of an automobile type to be developed; calculating a vertical distance value of the design reference point and the heel point, and determining the reference value of the front and back distance of the steering wheel center and the heel point on the basis of the vertical distance value of the design reference point and the heel point; on the basis of the reference value, determining a screening condition for reference automobile types, determining a plurality of reference automobile types which conform to the screening condition for reference automobile types, and fitting the vertical distance values of the design reference points and the heel points of the plurality of reference automobile types with the vertical distance values of the steering wheel centers and the heel points of the plurality of reference automobile types to obtain a first relation formula between the vertical distance parameter of the steering wheel center and the heel point and the vertical distance parameter of the design parameter point and the heel point; and on the basis of the vertical distance value of the design reference point and the heel point and the first relation formula, determining the vertical distance value of the steering wheel center and the heel point of the automobile type to be developed.
Description
technical field [0001] The invention relates to the technical field of automobile design, in particular to a method and a device for determining the vertical distance between the steering wheel center and the heel point. Background technique [0002] The latest national standard "Terms and Definitions of Vehicle and Trailer Types" (GB / T 3730.1-2001) has the following definition for a vehicle: a non-rail-mounted vehicle driven by power with 4 or more wheels, mainly used for : Carrying people and (or) goods; towing vehicles carrying people and (or) goods; special purpose. [0003] The theory of automobile design is used to guide the practice of automobile design, and the long-term accumulation of practical experience in automobile design and the development and progress of automobile production technology have continuously developed and improved the theory of automobile design. Automobile design technology is the method and means of automobile design, and it is the software a...
