Intelligent cruise control system and its control method

Abstract

The present invention relates to an intelligent cruise control system and a control method thereof including, according to the change of the vehicle's time target acceleration, realizing a learning mode according to a driver's selection mode or learning the driver's driving habits. According to the intelligent cruise control system of the present invention, it includes: a distance error calculation part, which uses the distance between the own vehicle and the preceding vehicle measured by the sensor and the target distance to calculate the distance error; a relative speed calculation part, which uses the distance measured by the speed measurement part The speed of the host vehicle and the preceding vehicle is used to calculate the relative speed; the driving mode selection unit is used to select the driving mode by the driver; the target acceleration calculation unit is used to calculate the first acceleration using the distance error and the first medium variable according to the selected driving mode, A target acceleration is calculated using the second acceleration calculated using the own vehicle speed and the second medium variable, and the third acceleration calculated using the relative speed and the third medium variable.

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.
