Smart cruise control system and control method therefor

Abstract

The invention relates to a smart cruise control system and a control method therefor. A selecting mode or a learning mode of learning driving habits of a driver is achieved according to changes of target accelerated speed with time of a vehicle. The smart cruise control system comprises a distance error calculating portion used for calculating a distance error by utilizing distance and target distance between a self vehicle and a front vehicle measured by a sensor, a relative speed calculating portion used for calculating relative speed by speed of the self vehicle and the front vehicle measured by a speed measuring portion, a driving mode selecting portion via which the driver can select driving modes, and a target accelerated speed calculating portion used for calculating target accelerated speed by utilizing first accelerated speed calculated by the distance error and a first medium variate and utilizing second accelerated speed calculated by speed of the self vehicle and a second medium variate and utilizing third accelerated speed calculated by relative speed and a third medium variate according to the selected driving modes.

Description

technical field [0001] The invention relates to an intelligent cruise control system and a control method thereof. More specifically, the present invention relates to an intelligent cruise control system and a control method thereof including implementing a learning mode according to a driver's selection mode or learning a driver's driving habit according to a change in a vehicle's temporal target acceleration. Background technique [0002] Generally speaking, the intelligent cruise control system of the vehicle is to make the driver track the set target speed, and execute the cruise control through the acceleration control of the vehicle. Then, in order to maintain an appropriate distance from the preceding vehicle, in cruise control, deceleration and acceleration control is performed using a front sensor that can recognize the vehicle in front or the environment of objects. [0003] On the other hand, the cruise control system of this kind of vehicle uses the front radar ...

AI Technical Summary

Problems solved by technology

[0004] However, the traditional cruise control system uses the set longitudinal speed of the vehicle and the set acceleration limit value to perform adaptive cruise control, which has the problem of failing to reflect the driver's diverse driving tendencies

That is to say, in the case of a driver who wants to accelerate and decelerate faster, or a driver who wants to accelerate and decelerate more smoothly, the degree of acceleration and deceleration of the traditional cruise control system cannot satisfy the driver.
