The invention provides a vehicle track prediction method and device, equipment, a storage medium and a product, and the method comprises the steps: collecting the motion state information of a target vehicle, and determining a first system noise variance and a first measurement noise variance of a first fuzzy controller based on a preset first fuzzy controller algorithm and the motion state information; and determining a predicted orientation angle and a predicted angular velocity of the target vehicle according to the variance and the motion state information, and determining a second system noise variance and a second measurement noise variance of a second fuzzy controller based on a preset second fuzzy controller algorithm, the predicted orientation angle, the predicted angular velocity and the motion state information. And according to a preset vehicle trajectory prediction model, the second system noise variance, the second measurement noise variance and the motion state information, predicting the motion trajectory of the target vehicle. The predicted motion trail of the target vehicle is more accurate, and the prediction precision is improved.
