Abstract

The speed of a vehicle is automatically controlled in a speed bump area located in the vicinity of a speed bump. Information about a speed bump is received from a navigation device, and a distance between the vehicle and the speed bump is calculated. If the calculated is less than a preset reference distance, it is determined that the vehicle is entering or has entered an area of the speed bump. Upon determining that the vehicle is in the speed bump area, a speed difference between a safe speed bump crossing speed and a current speed of the vehicle is computed, a required acceleration value is calculated based on the calculated distance to the speed bump and the speed difference, and the speed of the vehicle is controlled so that the vehicle decelerates or accelerates in accordance with the required acceleration value.

Description

technical field [0001] The present invention relates generally to automatic speed control technology for vehicles, and more particularly, to methods and apparatus for automatic speed control in the vicinity of speed bumps. By combining the speed bump information input from the navigation device with the automatic speed control system, the method and apparatus can, for example, automatically control the speed of the vehicle to accelerate or decelerate the vehicle in the speed bump area. Background technique [0002] Intelligent cruise control system refers to a system for implementing speed control so that the speed of a vehicle is maintained at the speed set by the driver when there is no vehicle in front of it. Intelligent cruise control system is also a system for A system that implements remote control so that when a vehicle in front appears, the distance to the vehicle in front is maintained at least a predetermined distance, thereby providing convenience and safety to t...
