The invention provides a vehicle cruise control method and device and a storage medium. According to the method, preprocessing is carried out based on platform cruise data, a road condition model is obtained through training of a clustering algorithm, vehicle information after coordination is obtained according to a target congestion level and a cruise control vehicle speed obtained by the road condition model, and predicted cruise optimization information is obtained according to the vehicle information after coordination based on a preset planning optimization algorithm. Initial cruise demand information is obtained according to the initial cruise state information, cruise advancing and retreating times are reduced on the congested road condition, predicted braking information is obtained according to the braking state information, and predicted cruise control information is obtained according to predicted cruise optimization information, the initial cruise demand information and the predicted braking information, so that brake stepping and gear shifting times are reduced; and the cruise control torque is calculated and obtained based on the predicted cruise control information, and vehicle cruise is realized by outputting the cruise control torque, so that high oil consumption is reduced during cruise under the congested road condition, and the operation cost of the commercial vehicle is further reduced.
