Nissan's new nav system focuses on safer, 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 will be available in Japan in the fall of 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 enhanced navigation system provides 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.

Nissan began large-scale intelligent transportation system tests of advanced vehicle-to-infrastructure communications in October 2006.

Nissan's system employs an optical beacon receiver, developed in the SKY project, which works in sync with infrastructure. It was adopted recently by the National Police Agency and the Universal Traffic Management Society of Japan (UTMS) for their Driving Safety Support System (DSSS).

This year, with the government's revamp of the road infrastructure, Nissan will incorporate a new feature that uses information on traffic and the status of nearby vehicles from optical beacons to warn drivers about situations that are difficult to see.

Intersection and Signal Warning: Using information transmitted from the DSSS on-road systems, the system will send audible and visual warnings when drivers approach some low-visibility intersections.

School Zone Alerts: 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. This feature is already 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, optimise engine braking and reduce fuel flow to increase fuel-efficiency. This feature is currently in use on the Nissan Eco series, a line of greener cars released in Japan in April.

Faster Route Searches: Using probe data sent to the Carwings Centre, this system supplies information for all roads (except alleys) in addition to that previously available via the Vehicle Information & Communication System (VICS). The centre also collects waiting-time data (e.g. when turning at an intersection) from vehicles at traffic signals and delivers it to other vehicles in the area.
