BSD(Blind Spot Detection) System: BSD warn the driver against collisions that may occur due to a lane change manoeuvre. BSD are intended to supplement the vehicle's interior and exterior rear-view mirrors. BSD are intended to detect vehicles to the rear and sides of the subject vehicle (see Figure). When the subject vehicle driver indicates the desire to make a lane change, the system evaluates the situation and warns the driver if a lane change is not recommended. The system will not take any automatic action to prevent possible collisions. Responsibility for the safe operation of the vehicle remains with the driver.
