Whole vehicle acceleration maximum transverse jitter evaluation method

The invention discloses a whole vehicle acceleration maximum transverse jitter evaluation method, which comprises the following steps of: determining the maximum included angle of a transmission shaft of a tested vehicle through the dispersion difference of vehicle postures between different vehicles, and ensuring the included angle lt of the transmission shaft of 99.7% of vehicles; a maximum angle; the axial derived force of the transmission shaft is maximized by adjusting the phase difference of the left and right transmission shafts. Due to the wide application of a constant velocity universal joint driving shaft, a vehicle is easy to transversely shake during accelerated driving, and the transverse shake of the whole vehicle is related to the section type selection of transmission shafts, the size of the included angle of the transmission shafts, the change of the working states of the left and right transmission shafts and the parameters of the whole vehicle. Parameters related to transverse jittering ar
