DEVELOPMENT OF AN INTELLIGENT CRUISE CONTROL SYSTEM

An intelligent cruise control system has been developed. The system consists of cruise control and headway distance warning functions. This paper describes the sensing system, the control algorithm, and the system effectiveness evaluated by various vehicle tests. The system consists of vehicle sensors, a laser radar and video camera that recognizes preceding vehicles, a controller, a throttle actuator, and automatic transmission, etc. The scanning type laser radar detects the distance and direction to the target object by measuring the elapsed time between emission of pulse beam and reception of reflected beam. The video camera is used to recognize the current traveling lane. The forward view road image obtained with the camera is processed and the lane boundaries are extracted with the edge extraction technique. When the vehicle is running on cruise control mode, the system adjusts engine output or transmission shift so as to maintain the headway distance, and issues a warning when approaching too close to a preceding vehicle. The operation switches for intelligent cruise control are the same as those for the conventional cruise control system. The center message display provides system operation status, such as set speed, headway distance, control status, and warning. The effectiveness of the intelligent cruise control in providing safe and comfortable driving was verified by various field tests.
