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 invention proposes an apparatus and method for controlling the velocity of a vehicle, and the apparatus and method are used for judging whether a driving road is inclined or not. According to the judgment results, the velocity of the vehicle is controlled on the basis of information received by a vehicle sensor. The apparatus comprises a monitoring part which is used for monitoring the acceleration of the lateral direction of the vehicle; a lateral acceleration judgment part which is used for judging whether the lateral acceleration is greater than a reference value or not; an inclined road judgment part which is used for judging whether the driving road is inclined or not if the lateral acceleration is greater than the reference value; and a velocity control part which is used for maintaining the current velocity of the vehicle if the driving road is inclined.

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 (bank 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 acceleration value is above a certain value, then it limits the target acceleratio...
