Abstract |
Adaptive Cruise Control System (ACC) is one of the safety critical embedded systems. This is an automotive sector driver assistance system which can help to prevent accidents by reducing the workload on the driver. Adaptive Cruise Control (ACC) is an advanced automotive feature that allows a vehicle’s cruise control system to adapt the vehicle’s speed to the traffic environment. A radar system attached to the front of the vehicle below bumper of vehicle is used to detect whether slower moving vehicles are in the ACC vehicle's path. If a slower moving vehicle is detected front of it, the ACC system will slow the vehicle down and control the time gap, between the ACC vehicle and the forward vehicle. If the system detects that the forward vehicle is no longer in the ACC vehicle's path, the ACC system will accelerate the vehicle back to its set cruise control speed. This basic functionality and working of this Adaptive Cruise Control System (ACCS) was simulated using MATLAB-Simulink software. In this paper we showed results i.e, speed of opposite vehicle and controlled speed of the vehicle. Both software and hardware safety analysis methods such as FMEA and FTA have also discussed. |
