Automobile inner chamber operating force comfort degree evaluating system and evaluating method

Abstract

An evaluation system and an evaluation method for comfort level of internal operating force of a vehicle are disclosed, characterized in that the system composition includes a vehicle-mounted data acquisition device composed of input / output devices including an analog-digital conversion data acquisition card, an acquisition channel, a vehicle-mounted computer motherboard, a keyboard and a display; for the operating devices, a displacement amount sensor for real-time measurement of an action force and an action force that is applied by a driver to internal operating devices of the vehicle is arranged, a parallel interface data transmission path of the computer is set based on the signal acquired by an external sensor as a data acquisition source of the data acquisition system, a plurality of data acquisition interfaces are utilized to data acquisition for different sensors simultaneously. The evaluation method is the evaluation for comfort level of degree of correlation of curves by comparing a standard curve of comfort level of the corresponding vehicle type with a real-time curve measured by the system and reflecting displacement amount variation characteristics of the action force and the action force that is applied by a driver to internal operating devices of the vehicle. The invention can evaluate comfort level of vehicle in accordance with practical requirement of carmaker.

Description

technical field [0001] The invention relates to a quality inspection system applied in automobile production sites, more specifically to an evaluation system and an evaluation method for the comfort degree of control force in an automobile interior for evaluating the quality of automobiles. Background technique [0002] At present, in the production of automobile manufacturers, the requirements of humanization have gradually become indispensable. For various operating devices in the interior of automobiles that have a direct relationship with the human body, they are required to meet the comfort requirements of the human body, especially those that are closely related to the human body. The comfort requirements of mechanical characteristics that are closely related to fatigue and labor injuries, such as the setting of the steering gear's rotational resistance, the design of the pressure value of the hydraulic transmission of the clutch pedal, etc., all need to meet the requir...
