Nissan Motor Co., Ltd. today announced it will demonstrate its advanced "All-Around Collision Free" prototype vehicle - complete with two all-new accident avoidance technologies- at the 15th World Congress on Intelligent Transport Systems (ITS). The ITS World Congress, to be held at New York City's Jacob K. Javits Center, from Nov. 16 - 20, showcases future vehicle-to-vehicle and vehicle-to-infrastructure communications systems. This is the first time the "All-Around Collision Free" prototype will be displayed in the United States and the world's first demonstration of Back-up Collision Prevention (BCP). The prototype also incorporates Side Collision Prevention (SCP) and two current production technologies, Distance Control Assist (DCA) and Lane Departure Prevention (LDP).

System Functions

System Configuration of Side Collision Prevention / Back-up Collision Prevention The "All-Around Collision Free" prototype vehicle further extends Nissan's "Safety Shield" concept to help protect the vehicle and its occupants from potential risks coming from multiple directions. Following is a brief overview of the key systems:

Side Collision Prevention: As the vehicle begins to change lanes, side-mounted sensors activate a warning if another vehicle is detected in the intended lane. A yaw mechanism is then activated through brake control of individual wheels on the opposite side of the vehicle, to help prevent a potential collision by moving the vehicle toward the center of the original lane of travel.

Back-up Collision Prevention: During a backing maneuver, such as backing out of a parking space, rear and side-mounted sensors detect objects in the path of the vehicle. If an object is detected, an alarm sounds and then the brakes are activated to help avoid a collision.

Distance Control Assist and Lane Departure Prevention: Distance Control Assist (DCA) detects the distance to objects in front of the vehicle. When the vehicle is approaching an object, DCA will display a warning symbol, sound an alarm, and move the accelerator pedal up against the driver's foot. If the throttle is not being applied, DCA will gently apply the brakes to help encourage deceleration.

Lane Departure Prevention (LDP) assists with maintaining lane position by detecting lane markers and calculating position relative to them. If the vehicle approaches the lane markers, a warning illuminates and an alarm sounds. If the vehicle continues to travel toward the lane markers, the system activates the yaw mechanism (described in SCP above) to help move the vehicle toward the center of the lane.

Both the DCA and LDP systems complement the SCP and BCP to move toward an "All-Around Collision Free" prototype. These warning systems and preventive safety features are designed to help support the driver in an intuitive manner with minimal intervention.
