摘要:
A controlling method of vehicle exhaust gas recirculation, an apparatus and an electronic device are provided in vehicle field. Before the GPF/DPF starts to work, controlling the EGR to cool the temperature of the recycled gas at a lowest gas temperature required being entranced into the engine; and after the GPF/DPF starts to work, according to a gas temperature change and an intake flow change of an air intake of the EGR, adjusting an opening of a valve arranged in a vent of the EGR and a working power of a pump arranged in a liquid duct of the EGR, for making the EGR to cool the gas recycled by the EGR in a safe temperature range required by the engine. The controlling method is associated controlled with a cooling system of the EGR, for ensuring the recycled exhaust gas temperature and the EGR rate in a suitable range.
