Abstract

The embodiment of the invention provides an intelligent vehicle cruise control method and device based on a real-time road condition to solve the problem that in the prior art, an oil saving effect is not ideal when a vehicle cruises under a slope road condition. The method includes the steps that for the vehicle in a cruise mode, position information of the vehicle and road condition information are obtained, wherein the road condition information comprises slope information; a travel mode of the vehicle is confirmed according to the obtained position information and road condition information, wherein the travel mode is a before-uphill mode or a before-downhill mode; and when it is confirmed that the vehicle is in the before-uphill mode or the before-downhill mode, the target cruise speed of the vehicle is correspondingly increased or decreased.

Description

technical field [0001] The invention relates to the technical field of vehicle cruise control, in particular to a vehicle intelligent cruise control method and device based on real-time road conditions. Background technique [0002] As a technology for automatic driving vehicles, vehicle cruise control technology has been widely used in passenger cars. According to its functions, it can be divided into constant speed cruise and adaptive cruise. The so-called constant speed cruise can refer to controlling the engine to stabilize the vehicle speed at the set speed The so-called adaptive cruise can refer to controlling the engine to stabilize the vehicle speed at the set cruising speed, and at the same time, by measuring the distance to the vehicle in front, the vehicle speed is controlled based on the distance so that the vehicle maintains the same distance as the vehicle in front. Cruise at a safe distance. [0003] In the existing vehicle cruise control technology, the crui...
