Abstract
Remarkable advances have taken place in chassis control technology, such as antilock brake systems (ABS), vehicle stability control(VSC) systems and so on. In addidtion ,the Pre-crash safety system (PCS) in order to reduce collision damage had been introduced. This system judges the collision probability based on output data from the Millimeter-wave Radar and helps driver brake operation. This paper describes a new assist system that incorporate a dynamic control system with forward monitoring technology. This new system helps drivers steer operation during the emergency collision avoidance, which was developed based on analysis of driver behavior in accidents.
