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. 本发明公开了一种行车舒适度评价方法，所述方法包括以下步骤，S1、确定振动的方向；S2、确定各个振动方向上的振动的强度：振动的强度以加速度均方根值来表示，单位为m/s2，S3、采用1/3倍频程法，对1/3倍频程中心频率的振动信号进行了频谱分析，得出评判指标；S4、按照不同的振动的时间，给出不同的振动极限值。本发明将加速度均方根值从时域转化到频域进行频谱
