An information processing method is executed by a computer and the method includes: obtaining first transported-object information that is transported-object information including a position and a weight of a transported object on a moving body; obtaining a weight of the moving body; generating information indicating a predicted steering angle center value by inputting the first transported-object information obtained and the weight of the moving body obtained into a model generated using second transported-object information, a weight of the moving body, and a steering angle center value of the moving body, the second transported-object information being older transported-object information than the first transported-object information; and outputting the information indicating the predicted steering angle center value to the moving body.
