Driving comfort evaluation method

Abstract

The invention discloses a driving comfort evaluation method, and the method comprises the following steps: S1, determining a vibration direction; S2, determining the intensity of the vibration in eachvibration direction: wherein the vibration intensity is expressed by an acceleration root-mean-square value, and the unit is m / s2, S3, adopting a 1 / 3 octave method to carry out spectral analysis on the vibration signal with the 1 / 3 octave center frequency, and obtaining an evaluation index; and S4, giving different vibration limit values according to different vibration time. According to the invention, the acceleration root-mean-square value is converted from the time domain to the frequency domain for spectral analysis so that the acceleration amplitude is associated with the frequency, andthe evaluation result is more real and reliable.

Description

technical field [0001] The invention relates to the technical field of evaluation methods, in particular to a method for evaluating driving comfort. Background technique [0002] A large number of facts show that when the car is running, if the body vibrates relatively strongly, it will cause discomfort such as nausea and vomiting to the occupants of the car, and research has further shown that even if the vibration is not strong, if the human body is exposed to vibration for a long time Also can feel tired, weak, this undoubtedly is uncomfortable, even unsafe for the driver. The proposed concept of driving comfort is an index to judge whether the occupants feel discomfort or fatigue due to body vibration when the car is running, and how much discomfort is caused, also known as ride comfort. There are many factors that affect ride comfort, including objective factors such as external vibrations, as well as people's own subjective feelings. Therefore, in the research process...
