Asia News:  Nissan debuts world’s first distance control assist and nav-enabled intelligent cruise control

Nissan Motor Co introduced the world's first Distance Control Assist and navigation-enabled Intelligent Cruise Control systems in the new Fuga, released in Japan in December.

The Distance Control Assist system helps control the distance between two vehicles under various traffic conditions, from congested urban roads to high-speed expressways.

The system determines the following distance of the driver's vehicle as well as the relative speed of both vehicles, using a radar sensor installed in the front bumper.

When a vehicle closes in on the vehicle ahead, the system activates the brakes to decelerate smoothly if the accelerator is not engaged. If the accelerator is engaged, the acceleration actuator is activated through a ‘push back’ mechanism to help the driver to release the pedal.If

the vehicle ahead slows down or brakes, requiring the driver to respond by braking, the system instantly alerts the driver through message and audio warnings, and simultaneously pushes back the accelerator to assist the driver to switch to the brakes.

The improved Intelligent Cruise Control system integrates route-information via the on-board navigation system to monitor the vehicle's cruising speed to match actual road conditions, e.g. the sharpness of the next curve on the road.

The system operates using information from a radar sensor installed in the front bumper. When following a vehicle ahead, the system controls following distance appropriately, using the driver's preset speed is the maximum limit. With no vehicle ahead, the vehicle cruises at the constant driver preset speed.

The new system features several pioneering technologies –

  • Full-speed range following function: Previous systems functioned only within the range of approximately 5–100 km/h, whereas the new system functions across the full-speed range, starting from zero.
  • World's first use of navigation map data: Using route-information fed through the on-board navigation system, the Intelligent Cruise Control system can modulate the vehicle-speed in anticipation of the next curve on the road. When approaching a curve, the system gradually decelerates, and as it clears the turn onto a straight road, the system seamlessly resumes to its original speed.
