Abstract
The disclosure relates to a predictive EGR control method and terminal device, and a storage medium. The method includes: calculating, if there is a slowdown section ahead of a vehicle, an engine output torque to be reduced for travelling from a current position 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 according to the engine output torque to be reduced or increased. 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.
