The invention provides a method and
system for acquiring and estimating road conditions based on vehicle-to-vehicle communication.
Road condition information of vehicles is acquired through a positioning unit, the
road condition information is transmitted to other vehicles through a vehicle-to-vehicle
communication unit,
road condition information of other vehicles is received, the
road condition information is processed through an
information processing control unit, road condition congestion degrees are acquired and displayed on an
electronic map through different colors, and
information sharing between the vehicles can be quickly achieved. The quantity of the acquired road condition information is large, the detailed
road congestion condition in a certain region surrounding the vehicles can be acquired, all roads in the region can be covered, consumed time in the whole process is short, road conditions can be updated in real time, and road condition services can be provided for specific persons and positions. Positions and time needing road condition
estimation are determined, matched road condition information is acquired from stored road condition information and output, the congestion conditions of the roads at a certain moment can be predicted in advance, and users can conveniently conduct path planning in advance.
