The invention discloses an empirical speed and empirical speed limit acquisition method and device, a vehicle, a medium and equipment, and belongs to the field of data processing. The method comprises the following steps: acquiring a plurality of speed values of a plurality of tracks passing through a road center point in a section of road; performing clustering and Gaussian distribution fitting on the plurality of speed values to obtain a preset number of Gaussian fitting speed distribution curves, and dividing the speed at the road center point into a low-speed interval, a normal interval and a high-speed interval according to the Gaussian fitting speed distribution curves, the preset number of Gaussian fitting speed distribution curves are in one-to-one correspondence with the low-speed interval, the normal interval and the high-speed interval; using the speed values of the normal interval and the high-speed interval to obtain an empirical speed at the road center point; and obtaining the empirical speed limit at the center point of the road by using the speed value of the high-speed interval. According to the method, the low-speed interval is effectively recognized, intuition is achieved, calculation of the empirical speed and the empirical speed limit is optimized, and the result is more accurate.
