The invention discloses a method of reducing emission of exhaust pollutants and a vehicle. The vehicle comprises an accelerating pedal location sensor, an engine controlling module, an automobile OBD connector, an accelerator location intelligent controller and a pollutant controlling module. The accelerating pedal location sensor, the accelerator location intelligent controller and the engine controlling module are connected through signals. Output signals of the accelerator location intelligent controller are changed in real time by the pollutant controlling module. Controlling signals are output to the engine controlling module by the accelerator location intelligent controller. According to the method of reducing emission of exhaust pollutants and the vehicle, not only is the emission of exhaust pollutants reduced, but also a good driving habit of a driver is developed, and driving economy and safety are enhanced.
