Abstract
Recently the Advanced Driver Assistance (ADAS), which helps mitigate car accidents has been developed using environmental detection sensors , such as long and short range radars , wide dynamic range cameras, ultrasonic sensors and laser scanners, Among these detection sensors , radars can quickly provide drivers with reliable weather conditions , in Adaptive Cruise Control System (ACCS), these radars can detect object in-path and in the adjacent lane and is proposed for use in (ACCS) using radar components , such as an antenna , transceiver module , transceiver control, target detection . According to the perspective and issues in the future development of the ACCS radars are described.
Keywords: Automotive Radar, Collision Mitigation, Adaptive Cruise Control, Acceleration and Deceleration, 77 GHz & 24 GHz.
1.INTRODUCTION
The system uses a three-beam radar sensor. This electronic eye monitors the road ahead of the car - up to 120 meters. When a car appears in the lane ahead - as in the above picture - the system calculates its location, movement and relative speed, using the reflected radar waves. The system is able to recognize whether a particular vehicle is occupying the lane ahead. As soon as the car ahead changes lanes again, your vehicle picks up speed again, accelerating to the same constant speed as before. ACC adjusts your car 's speed to the changing flow of the surrounding traffic.If a vehicle is detected in the lane ahead, the ACC system adjusts the speed of the vehicle by slowing the engine or by gently applying the brakes, and then holds the appropriate constant distance. These beams reflect off the vehicles ahead.
