The invention discloses an auxiliary driving method and device, electronic equipment and a storage medium, and aims to accurately obtain visibility representing different weather conditions in an external environment and ensure that a vehicle can adopt a proper driving strategy, so that the reliability of automatic driving is improved. The auxiliary driving method comprises the following steps: acquiring a dark channel image of an external environment; inputting the dark channel image into an atmospheric physical scattering model to obtain an actual transmissivity corresponding to the external environment; determining actual visibility corresponding to the actual transmissivity based on a pre-stored corresponding relationship between the transmissivity and the visibility; determining a target driving strategy corresponding to an actual visibility interval where the actual visibility is located based on a pre-stored corresponding relationship between the visibility interval and the driving strategy; and driving based on the target driving strategy.
