Embodiment Construction

[0036] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0037] See figure 2 , the relationship between the various parts of the steering wheel steering system is as follows: the steering wheel steering system 12 (steering wheel and steering column) root connector 10 is fixed together, the connector 10 and the guide sleeve 8 are fixed by bolts 11, and the screw 9 fixes the guide sleeve 8 With the shaft 6, the shaft 6 is connected with the T-shaped guide rail 3 by a bent plate 5.

[0038] X-direction degree of freedom: loosen the T-shaped bolt 2, and use the T-shaped bolt 2 to slide along the T-shaped guide rail 1 to realize the freedom of front and rear X-direction movement; when fixing, only need to tighten the T-shaped bolt.

[0039] Z-direction degree of freedom: loosen the T-shaped bolt 4, and use the T-shaped bolt 4 to slide along the T...

Abstract

The invention relates to a system for evaluating a steering system of a multiple-degree-of-freedom steering wheel. A test platform for the steering system of the steering wheel for man-machine subjective evaluation uses the steering system of the multiple-degree-of-freedom steering wheel by a test based on man-machine engineering and sets related parameters according to practical situations so as to adapt to a plurality of groups for an experiment and verification. The platform for the steering system of the steering wheel comprises: (1) a basic platform, which is used for arranging a sub-platform for the steering system of the steering wheel so as to realize X-direction movement and Z-direction movement of the steering system, and (2) the sub-platform for the steering system of the steering wheel, which is used for arranging an instrument crossbeam, a steering column and the steering wheel so as to realize Y-direction movement of the steering system for the steering wheel and angular parameterization of the steering wheel.

Description

technical field [0001] The invention relates to a multi-degree-of-freedom steering wheel steering system for human-machine subjective evaluation, in particular to an evaluation system and an evaluation method for a multi-degree-of-freedom steering wheel steering system. Background technique [0002] With the development of the global automobile market and increasingly fierce competition, vehicle ergonomics performance is becoming an important factor affecting user purchase behavior and user satisfaction, and human-machine comfort has attracted more and more attention from major automobile manufacturers. At present, when vehicles are being developed in the direction of ergonomics, the layout of the steering wheel and steering system is based on some empirical data or data layout obtained from measurements on competing models. This traditional method, which mainly relies on experience and reverse layout, cannot be evaluated subjectively, and deviations often occur, and it is a...
