The VDC(Vehicle Dynamics Control) is a control system that tries to improve stability of a vehicle under lateral motion. The system is getting much attention in the field of research since it can be implemented with little extra cost in a vehicle equipped with the ABS/TCS system. A lateral vehicle motion especially on a slippery road can lead to a hazardous situation such as plough or spin, and the situation can even worsen by the driver's inappropriate response. In this paper, a fuzzy control system has been developed that yields a direct yaw moment signal by which the vehicle can gain stability during cornering. The controller takes the rear wheel slip angle and the yaw rate as input. A simulation has been conducted to evaluate the performance of the designed VDC and the results indicated that the controller can successfully improve vehicle stability under potentially dangerous driving conditions.

Present automotive maker is admitted the technology-power by developing unique technique. It is a dangerous that we make a certain of a vehicle in the blind spot at the high speed. To avoid this dangerous situation, Equipment making a alarm, when a detection vehicle in the blind spot is necessary. Driver has a Jot of concerning for vehicle safety. Especially, Alarm system in the safety system will be constructed in the near future.<br/> BCWA system include high level techniques for sensor application, object detection algorithm, and ECU design<br/>

In this paper, an ECU-in-the-loop simulation system is const겨cted in order to verify the performance of a semi-active suspension controller for tracked vehicles. This system consists of a real-time vehicle simulation model based on multi-body dynamics formulation, semi-active in-arm suspension unit model, real-time simulation hardware where the simulation model is downloaded, and prototype ECU hardware and software which adopt the skyhook control algorithm to improve the vehicle motion especially in cross-country driving. Real-time hardware-in-the-loop simulation results show the control functions in ECU has a proper performance.<br/> <br/>

In this paper, an ECU-in-the-loop simulation system is constructed in order to design semi-active suspension controller and verify the performance of that. This system consists of a real-time vehicle simulation model based on multi-body dynamic formulation, in arm type suspension unit model, real-time simulation hardware where the simulation model is downloaded, and prototype ECU hardware and software which adopt the skyhook control algorithm to improve the vehicle motion especially in driving. Real-time hardware-in-the-loop simulation results show the control functions in ECU has a proper performance.<br/>
