Abstract
The application provides a vehicle control method, device and vehicle. The vehicle control method comprises the following steps: determining the position relationship between the vehicle and a target road; the target road comprises a closed road or a semi-closed road; in the case that the target distance between the position relationship and the target position of the vehicle and the target road is less than or equal to a preset distance, determining the second target torque of the engine based on the first target torque of the engine of the vehicle and the first correction coefficient; and determining the second target rotating speed of the generator based on the first target rotating speed of the generator of the vehicle and the second correction coefficient; controlling the engine based on the second target torque and controlling the generator based on the second target rotating speed; wherein the first correction coefficient is determined based on the power difference of the vehicle, the real-time vehicle speed and the first mapping relationship; the second correction coefficient is determined based on the power difference of the vehicle, the real-time vehicle speed and the second mapping relationship; and the power difference refers to the difference between the real-time power of the vehicle and the target power.
