Embodiment Construction

[0030] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, reference symbols are attached to components in each drawing, and care should be taken to assign the same symbols as much as possible to the same components even though they are shown in other drawings. In addition, when it is judged that a detailed description of a related well-known configuration or function makes the gist of the present invention unclear based on the description of the present invention, the detailed description will be omitted. In addition, preferred embodiments of the present invention will be described below, but the technical idea of ​​the present invention is not limited thereto, and of course can be variously modified by those skilled in the art.

[0031] figure 1 It is a block diagram schematically illustrating a vehicle speed control device according to a preferred embodiment of the present invention.

Abstract

The present invention proposes a vehicle speed control device and method that judges whether a traveling road is a sloped road, and controls the vehicle speed based on information received from a vehicle sensor based on the judgment result. A vehicle speed control device according to the present invention includes: a monitoring unit that monitors the lateral acceleration of the own vehicle; a lateral acceleration judging unit that judges whether the lateral acceleration is equal to or greater than a reference value; an inclined road judging unit that judges whether the lateral acceleration If it is above the reference value, it judges whether the road on which the own vehicle is traveling is an inclined road; and the speed control unit maintains the current speed of the own vehicle if it determines that the road on which the own vehicle is traveling is an inclined road.

Description

technical field [0001] The present invention relates to an apparatus and method for controlling the speed of a vehicle. More specifically, it relates to an apparatus and method for controlling velocity of vehicle considering slope of road (Apparatus and method for controlling velocity of vehicle considering slope of road). Background technique [0002] When there is no preceding vehicle in the Smart Cruise Control system, the driver maintains the set speed while driving in FCC (Free Cruise Control) mode. [0003] However, when entering a curve while driving in FCC mode, the vehicle will receive lateral acceleration according to the speed. At this time, if the vehicle is driven above the speed limit, the vehicle will leave the lane due to the influence of the lateral acceleration. [0004] In order to prevent the same phenomenon, control logic that limits the target acceleration has recently been installed in the vehicle. Its control logic, if the measured lateral accelerat...
