The invention discloses a vehicle track determination method and device and a storage medium, and the method comprises the steps: obtaining a preset track curve of a target vehicle, and the preset track curve comprises a plurality of to-be-determined coefficients; obtaining real-time operation parameters of the target vehicle, and determining each to-be-determined coefficient based on the real-time operation parameters of the target vehicle to obtain a plurality of target coefficients; and obtaining a target trajectory curve based on the preset trajectory curve and the plurality of target coefficients. According to the technical scheme, after the target preset trajectory curve is obtained, the target vehicle in front of the vehicle is followed in real time in the congestion scene, and the algorithm is simple and easy to operate; and meanwhile, the control of the automatic driving system on the vehicle is optimized, so that the vehicle following safety is improved.
