The invention belongs to the technical field of wireless distance measurement and positioning and particularly relates to a vehicle wireless distance measurement method based on standard deviation iteration. The vehicle wireless distance measurement method mainly comprises four steps: A, performing correlation calculation and normalization processing on IEEE802.11p protocol receipt signals; B, performing grouping summation on the statistical result to obtain a summation sequence S; C, judging the normalized standard deviation stdS of the group comprising 16 samples in at least 160 samples in front of the maximum value of the current summation sequence S, if stdS [1] greater than 0.9 and stdS [10] smaller than 0.1 are not met, assigning the maximum value of the summation sequence S as 0 and continuing loop iteration, otherwise, returning to the subscript PeakIndex of the maximum value in the summation sequence S; D, calculating to obtain the distance according to the PeakIndex. According to the invention, correlation, summation and standard deviation iteration are used in wireless positioning of the IEEE802.11p protocol for the first time and can improve the vehicle distance measurement accuracy under the multipath, non-orthoptic and high Doppler shift environment.
