The invention belongs to the technical field of vehicles, and discloses a vehicle state prediction method and device, equipment and a storage medium. The method comprises the following steps: establishing a target dynamic model of a to-be-predicted commercial vehicle according to vehicle speed information, vehicle total mass, distance information and tire stress information of the to-be-predicted commercial vehicle; establishing a target kinematics model according to the acceleration information and the speed information; obtaining a vehicle state model according to the target dynamic model, the target kinematic model and a preset forward Euler integral mode; inputting sensor data collected by a vehicle-mounted sensor to the vehicle state model to obtain an initial state vector; and performing state prediction according to the initial state vector to obtain state prediction information of the commercial vehicle to be predicted. The vehicle state model is obtained through the dynamical model and the kinematic model, the initial state vector is obtained by inputting the sensor data, and finally the state prediction information is obtained through prediction, so that state prediction of the commercial vehicle is realized, and the accuracy of the state prediction result is improved.
