| description | The invention discloses a vehicle exhaust gas recirculation control method and device, a terminal and a motor vehicle. The method comprises the steps that first air humidity is obtained based on weather service software of the vehicle; light data and rainfall data of the vehicle are collected and input into a pre-established humidity model, and the humidity model outputs second air humidity; based on the Internet of Vehicles technology, third air humidity is obtained through a weather service provider; the first air humidity, the second air humidity and the third air humidity are subjected to effectiveness and reasonability judgment, and judgment results are obtained; determining the final target air humidity in combination with the judgment result and a preset priority; and controlling the opening degree of exhaust gas recirculation of the vehicle by using the target air humidity. On the basis that material cost is not increased, vehicle exhaust gas recirculation opening degree control is achieved through a |
