PURPOSE: A system for controlling the distance between cars is provided to accurately measure whether a driving car changes a lane or not by measuring a position angle of the driving car and comparing the position angle of the driving car with the position angle of a preceding car. CONSTITUTION: A system for controlling the distance between cars comprises: a radar unit(100) monitoring a preceding car; a position angle sensor(200) measuring the position angle of a driving car; a controller(400) which measures the position angles of the preceding car and the driving car and deciding the lane change of the driving car when the position angle of the preceding car is same as the position angle of the driving car; a steering wheel sensor measuring a steering wheel angle of the driving car; and a yaw rate sensor measuring a rotation angular speed. The position angle of the driving car is measured using the steering wheel angle and the rotation angular speed. |
