Exceptional road-condition warning device, system and method for a vehicle

摘要

An exceptional road-condition warning device, system and method for a vehicle are provided. The system includes an information processing device and a display device. The display device provides real-time and advance warning information to a driver of the vehicle. The system may notice the driver and passenger in advance to respond to an exceptional road condition before the vehicle approaches the occurring place of the road condition through a back-end cooperative self-learning mechanism. The back-end cooperative self-learning mechanism may collect the exceptional road conditions from different vehicles and update the database automatically to maintain the accuracy. The back-end cooperative self-learning mechanism further shares the information stored in the database with the databases installed in the vehicles by a bidirectional communication manner to update the information inside the database of the vehicles for the information processing device.
