Abstract
The present application relates to the technical field of vehicle controlling technology, and provides a method and a device for gradient calculating. The method for gradient calculating includes: acquiring current operating parameters of the vehicle, wherein the current operating parameters include a current longitudinal acceleration, a current lateral acceleration, a current vehicle acceleration, and a current vehicle speed; determining a first influence value of the current lateral acceleration on the current longitudinal acceleration according to the current lateral acceleration and the current vehicle speed; determining a second influence value of the current vehicle acceleration on the current longitudinal acceleration according to the current vehicle acceleration and the current vehicle speed; correcting the current longitudinal acceleration according to the first influence value and the second influence value; and determining the gradient value based on the corrected current longitudinal acceleration.
