Distance control assist technology

  • 13-Mar-2009 08:26 EDT

The distance control assist (DCA) system from Nissan North America determines a driver’s following distance as well as the relative speed of both vehicles using a radar sensor installed in the front bumper. When a vehicle approaches close to the front vehicle and the accelerator is not engaged, the system activates the brakes to decelerate smoothly. If the accelerator is engaged, the acceleration actuator is activated through a push back mechanism to help the driver release the pedal. When the vehicle ahead slows down or brakes, requiring the driver behind to brake, the system alerts the driver through message and audio warnings and pushes back the accelerator to help the driver switch to the brakes. The DCA debuted on the 2009 Infiniti FX.
