Nissan Develops Turn Assistant for Curvy Roads (July 28, 2009) — Nissan has developed a new system that combines real-time GPS navigation with existing radar safety tech to help a driver decelerate, brake or make smooth turns on curvy roads.

nissanThe Navigation-Cooperative Intelligent Pedal uses GPS mapping data to detect an oncoming bend, then strategically decelerates or applies the brakes.

When the navigation system indicates a curve is looming, the accelerator pedal physically moves upward. Then the system activates the brakes. The point is to reduce a driver’s workload on winding roads, such as Japan’s notoriously curvy mountain highways.

The Navigation-Cooperative Intelligent Pedal works along with Nissan’s new Active Stability Assist system, which synchronizes braking, steering and engine responses.

The system monitors a driver’s steering and acceleration/braking patterns, and steps in with either braking or the application of engine torque to each of the four wheels to help smooth vehicle responses.

During braking, the system judges the distribution of force to each of the four wheels depending on the radius of a curve.

Nissan says both systems will be introduced on the new Fuga, a car US buyers know as the Infiniti M, in Japan in fall 2009.
