– Nissan will test its “slip-hazard warning system” in Hokkaido, Northern Japan, between November 2007 and March 2008, according to Telematics Update
. The system uses real-time road condition data collected from probe cars. Nissan expects about 100 vehicles equipped with the Carwings navigation system to provide the necessary real-world driving sample data for this project.
The system combines data from its ITS and in-vehicle ABS to issue real-time voice alerts as the vehicle approaches a slippery point in the road. Nissan hopes to examine the accuracy, effectiveness, and feasibility of the system using various probe data, for future commercial application.
In addition to the slip-hazard warning system, the newly improved Carwings system offers:Real-time map of slippery points relative to current vehicle position based on data received via its Carwings communications system and probe information.
Statistical data based on historical records of the slippery points.
Cumulative data on accident points.
Location of reported skid accidents in the most recent years and from past years.
