Method for predicting eye positions of driver of high-power wheeled tractor

Abstract

The invention discloses a method for predicting eye positions of a driver of a high-power wheeled tractor, and belongs to the technical field of ergonomics application. The method comprises steps of firstly, quantitatively describing eye position distribution of a tractor driver through an eye position determination experiment; analyzing and processing the experimental data, and drawing an eye position scatter diagram; then determining candidate predictive factors of cab layout parameters and driver human body measurement parameters; then establishing a tractor driver eye position prediction model based on the anthropometric parameters and the tractor driving layout by adopting a multiple linear regression method; and finally, testing the prediction effect of the model. The prediction method provided by the invention can accurately establish the eye position prediction model of the high-power wheeled tractor driver, and has the advantages of strong applicability and good prediction effect, thereby effectively solving the problems that the visual field of the tractor cab is inconvenient to design, the visual field of the driver is difficult to check and the like.

Description

technical field [0001] The invention belongs to the application technical field of ergonomics, and in particular relates to a method for predicting the eye position of a driver of a high-power wheeled tractor. Background technique [0002] The field of view is of great significance to the safe driving of the driver, and the eye ellipse is the main tool for the cab field of view and the layout design related to the field of view. The so-called ocular ellipse refers to the statistical distribution pattern of the eye position of drivers of different sizes sitting in the car in a normal posture. It is named for its oval shape. At present, as the main tool of field of view and human-machine design related to field of view, the eye ellipse has been widely used in the field of view design of cars and commercial trucks. In contrast, in the field of view design of tractors, ergonomics is less applied, and there is currently no eye ellipse model for tractors. However, on the one han...
