Energy conservation control method and system in vehicle slope rushing travel

Abstract

The invention provides an energy conservation control method and system in vehicle slope rushing travel and belongs to the technical field of vehicle energy conservation. The method includes the stepsthat geographic information related to slope rushing travel is acquired; a slope rushing operation physical model is established; based on the current working state of a vehicle engine, the geographic information and vehicle parameters, the slope bottom working state and the slope top working state of the engine are calculated, and the slope rushing situation type to which a vehicle belongs is confirmed; based on the slope rushing operation physical model, the slope bottom vehicle speed allowing the vehicle to travel to the slope top from the slope bottom without downshifting is calculated; adriver is reminded of the slope bottom vehicle speed obtained through calculation in a voice mode; and based on a received slope bottom vehicle speed reminder, the driver adjusts the speed used whenthe vehicle reaches the slope bottom to the slope bottom vehicle speed. In addition, the invention provides the energy conservation control system in vehicle slope rushing travel. By the adoption of the technical scheme, on the premise that it is guaranteed that the vehicle smoothly climbs a slope, fuel consumption is reduced, and the effects of energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention belongs to the technical field of vehicle energy saving, and in particular relates to an energy-saving control method and system for a vehicle running uphill. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] Vehicles often encounter slope climbing situations during driving. How to accurately and timely prompt the driver to make reasonable operations to reduce fuel consumption during the slope climbing process is one of the problems that need to be solved in energy-saving driving. In the prior art: On the one hand, the speed at the bottom of the slope cannot be accurately controlled during the climbing process of the vehicle, and the speed at the bottom of the slope is often too large or insufficient. Excessive speed at the bottom of the slope will inevitably lead to large fuel consumption, large gas emissions, and easy pollution , ...

Problems solved by technology

In the prior art: On the one hand, the speed at the bottom of the slope cannot be accurately controlled during the climbing process of the vehicle, and the speed at the bottom of the slope is often too large or insufficient. Excessive speed at the bottom of the slope will inevitably lead to large fuel consumption, large gas emissions, and easy pollution Insufficient speed at the bottom of the slope will lead to difficult climbing and other safety risks; on the other hand, the process of vehicle climbing often involves gear shifting, the control process is cumbersome, not convenient enough, and prone to various accidents
