The present invention relates to a predictive EGR control method and terminal device, and a storage medium. The method includes: determining, according to electronic horizon data ahead of a vehicle, whether there is a slowdown section ahead of the vehicle, and if so, calculating an engine output torque to be reduced for travelling from a current position of the vehicle to a start position of the slowdown section and/or an engine output torque to be increased for travelling from the start position of the slowdown section to an end position of the slowdown section, and thereby adjusting an EGR rate of the vehicle at the current position of the vehicle according to the engine output torque to be reduced and/or adjusting the EGR rate of the vehicle at the start position of the slowdown section according to the engine output torque to be increased. By making full use of the information of the terrain ahead provided in the electronic horizon, before the vehicle running at a high load enters the slowdown section, an EGR valve can be opened in advance to increase the EGR rate, thereby reducing harmful gas emissions.
