An evaluation method for man-machine interface in vehicle cab

Abstract

The invention discloses an evaluation method for a vehicle cab man-machine operation interface. The evaluation method comprises the following steps: 1. selecting seat entity points related to a human body as an evaluation reference coordinate system and constructing a geometric model between a human and element contact points in the vehicle cab man-machine operation interface; 2. constructing a dimension geometric model between the human and the element contact points during operation in the evaluation coordinate system, solving the angles of each human joint when the human is operating elements through a single-variate triangular model which is obtained by solving the geometric model based on Newton iteration numerical algorithm; and 3. comparing the angles of each human joint when the human is operating the elements to a human comfortable joint angle scope and evaluating the comfortableness of the cab man-machine operation interface. The evaluation method provided by the invention helps to solve problems of evaluation difference caused by different human body data due to sole dependence on international standard specified installation area data; and besides, the evaluation method also has the advantages of accurate evaluation result, quite high reliability, high practicality and high popularization and application value values.

Description

technical field [0001] The invention belongs to the technical field of human-machine manipulation interface evaluation, and in particular relates to a method for evaluating the man-machine manipulation interface of a vehicle cab. Background technique [0002] The human-machine interface refers to the area where people and machines connect and interact. For example, the steering wheel, pedals, joysticks and various instruments in the cab of a car form a driving human-machine interface. The cab of a motor vehicle is a Class more complex man-machine interface. [0003] Among the human-machine interface factors, the geometric position of the components plays an important role in the system design. Improper geometric position design will put the operator in a state of static and continuous tension, resulting in reduced blood supply to local soft tissues, muscle tissue ischemia, Anaerobic metabolism increases, leading to the occurrence of various occupational diseases.
