The utility model provides an engine low-pressure EGR control system and a vehicle, and relates to the technical field of vehicles. The low-pressure EGR control system of the engine comprises an engine system, an EGR control system and an EGR control system, wherein the engine system comprises an air inlet pipeline, an exhaust pipeline and a supercharger pressing wheel; wherein the air inlet pipeline is arranged on the air inlet side of the engine system, and air flows into the engine system through the air inlet pipeline. And the EGR system communicates with the gas inlet pipeline and the gas outlet pipeline and is used for introducing EGR gas of the gas outlet pipeline into the gas inlet pipeline. A heating device is arranged at the air inlet pipeline, air and EGR gas form mixed gas in front of the heating device and then flow into the heating device, and the mixed gas is heated by the heating device to the temperature higher than the dew point temperature of the mixed gas and then flows through a superchar
