The invention relates to the technical field of intelligent driving, in particular to a lateral motion control method and device for a vehicle, and the method comprises the steps: calculating a current control output prediction sequence of a current work period based on the target lateral acceleration of the vehicle, and detecting whether the current control output prediction sequence meets a preset target criterion condition or not, if the current control output prediction sequence meets the preset target criterion condition, the vehicle is controlled to perform lateral movement according to the current control output prediction sequence, and otherwise, updating is performed based on a pre-constructed target learning algorithm until the control output prediction sequence meets the preset target criterion condition. According to the embodiment of the invention, iterative learning solution can be carried out on the steering wheel angle control quantity of the vehicle based on the target lateral acceleration of the vehicle, so that the efficient control of the lateral movement of the vehicle is realized, the adaptability and accuracy of the lateral control of the vehicle under various working conditions are improved, and the control precision of the lateral movement of the vehicle is higher.
