SMART CRUISE CONTROL SYSTEM USING RADAR amp; SPEED SENSOR AND THE CONTROL METHOD

摘要

PURPOSE: An adaptive cruise control system using a radar and a speed sensor and a method thereof are provided to improve the pause control precision of a following vehicle, thereby increasing ride comfort and stability. CONSTITUTION: An adaptive cruise control system using a radar (100) and a speed sensor (200) includes the radar which senses a relative velocity and relative distance of a preceding vehicle and a control unit (300) which controls distance between the preceding vehicle and a running vehicle which is a control target based on the sensed data of the radar. An adaptive cruise control system using a radar and a speed sensor comprises: a step of checking the stop of a preceding vehicle; a step of using a relative velocity and relative distance data of the preceding vehicle received from the radar of a running vehicle which is a control target in order to control a distance between vehicles; a step of calculating the relative velocity and relative distance of the preceding vehicle by using the sensed data received from the radar of the running vehicle when the stop of the preceding vehicle is checked; and a step of using the calculated relative velocity and relative distance data as adaptive cruise control data.
