Nissan Motor Co., Ltd. today announced an enhanced automotive navigation system design that utilizes intelligent transportation system (ITS) infrastructure and other advanced technology to promote safer and greener driving. The new navigation system – the world’s first to incorporate ITS information in a production vehicle – will debut on the next generation Nissan Fuga, which goes on sale in Japan in fall 2009.
The navigation system includes four advanced features in addition to the standard navigation functions:
* Intersection / signal warning
* Elementary School-zone alerts
* Navigation-linked speed control
* Enhanced route search and calculation
The goal of the enhanced navigation system is to provide safety-related information to drivers to help prevent accidents at intersections and raise awareness for safer driving. The system also incorporates a green-driving feature already introduced on select Nissan models.
* Intersection and Signal Warning
Using information transmitted from the Driving Safety Support System (DSSS) on-road systems, drivers can receive audible and display warnings when approaching some low-visibility intersections. The driver can decide whether the information is necessary to act on or not, depending on driving conditions. This is the first system of its kind utilized in a production automotive navigation system.
School Zone Alerts
The new navigation system’s mapping database now includes school zones. When the vehicle enters an elementary school zone and the system determines that a safety warning is appropriate, based on real-time vehicle information (speed, acceleration, braking, etc.), it provides audible and display warnings to direct driver attention. This feature is available in the new Nissan Skyline Crossover, which was released in July.
Navigation-linked Speed Control
Using navigation system information such as the sharpness of a curve or the distance to a tollgate, the system can control the vehicle’s engine and transmission, optimize engine braking and reduce fuel flow to help make driving more fuel-efficient. This feature is currently in use on the Nissan Eco (“NECO”) series, a line of greener cars released in Japan in April.
