Abstract

The invention discloses an identification method for a ramp gradient. The method comprises the following steps: according to a vehicle driving force formula, calculating by using parameters and a speed of a vehicle, to obtain a driving force, a rolling resistance, an accelerating resistance and an air resistance of the vehicle, acquiring a final gradient resistance, and according to the gradient resistance, calculating to obtain a final value of slope. The above technical scheme is used, the vehicle is capable of accurately identifying the ramp gradient by itself, and according to the gradient, judging whether to open an electronic parking function and an electronic parking automatic release function, while the vehicle is started in a half-ramp, effectively preventing a vehicle sliding phenomenon, improving product quality, and providing maximum guarantee for travelling safety of a user.

Description

technical field [0001] The invention belongs to the technical field of vehicle running control. More specifically, the present invention relates to a method for identifying the gradient of a ramp. Background technique [0002] Facing the dual pressure of energy conservation and environmental protection, the automobile industry must vigorously develop new energy vehicles if it wants to develop sustainably. Among new energy vehicles, plug-in hybrid vehicles are a transitional product from traditional fuel vehicles to pure electric vehicles. Due to technical reasons, new energy vehicles are always difficult to control when starting on a half slope. In the prior art, the phenomenon of driving force shaking and jumping occurs on a slope. [0003] Therefore, people hope that the vehicle itself can identify the slope of the slope, and then judge whether to turn on the electronic parking function and the automatic release function of the electronic parking according to the slope,...
