Back-up Collision Prevention Technology Debuted

Nissan's 'All-Around Collision Free' Prototype Unveiled in NYC

Recently, Nissan Motor Company debuted its advanced "All-Around Collision Free" prototype vehicle - equipped with two innovative accident avoidance technologies - at the 15th World Congress on Intelligent Transport Systems (ITS).

The ITS World Congress was held at New York City's Jacob K. Javits Center, from Nov. 16 - 20, and showcased future vehicle-to-vehicle and vehicle-to-infrastructure communications systems.

This event was the world premiere Nissan's 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).

By helping protect the vehicle and its occupants from potential risks coming from multiple directions, the "All-Around Collision Free" prototype vehicle further enhances Nissan's "Safety Shield" concept. Here is a brief overview of its key systems:

• Side Collision Prevention: When the vehicle begins to change lanes, side-mounted sensors activate a warning if another vehicle is detected in the new lane. Then the brake control of the individual wheels activates a yaw mechanism on the opposite side of the vehicle, helping prevent a potential crash by moving the vehicle toward the center of the original lane of travel.

• Back-up Collision Prevention: When performing a backing move, such as backing out of a parking space, objects in the path of the vehicle are detected by rear and side-mounted sensors, an alarm rings, then the brakes are employed to help avoid a collision.

• Distance Control Assist and Lane Departure Prevention: Distance Control Assist (DCA) determines the distance to objects in front of the vehicle. If the vehicle is nearing an object, DCA will display a warning symbol, ring 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) helps maintain lane position by detecting lane markers and determining the vehicle’s position relative to them. If the vehicle nears the lane markers, a warning illuminates and an alarm sounds. If the vehicle continues to approach the lane markers, LDP activates the yaw mechanism to assist the vehicle in moving toward the center of the lane.

In the "All-Around Collision Free" prototype, all warning systems and preventive safety features are designed to help intuitively support the driver, with minimal intervention.

Nissan's "Safety Shield" pre-crash and crash protection technologies are an advanced, proactive approach to auto safety, helping the driver avoid dangerous circumstances that vehicle can’t avoid.
