The invention relates to a train control method, a storage medium and a vehicle-mounted controller. The problems that the train speed grading control precision is low, and the limit performance of a train motor cannot be used are solved. The method comprises the following steps: acquiring a command speed of a train and a current speed of the train; according to a preset elliptic curve algorithm, on the basis of a difference value between the command speed and the current speed, a major semi-axis and a minor semi-axis representing an ellipse are determined, so that a target elliptic curve in a preset coordinate system is obtained, a first axis perpendicular to the major semi-axis in the preset coordinate system represents acceleration, and a second axis perpendicular to the minor semi-axis in the preset coordinate system represents acceleration; a second axis perpendicular to the short half axis represents the speed change time, and the area of an area defined by the target elliptic curve, the first axis and the second axis is equal to the absolute value of the difference value of the command speed and the current speed; and according to the target elliptic curve, representing a mapping relation between the speed change time and the acceleration of the train, and controlling the train to run at a variable speed.
